Significant Accounting Policies (Policies)	6 Months Ended
Significant Accounting Policies (Policies)	Jun. 30, 2019
Accounting Policies [Abstract]
Revenue from Contract with Customer [Policy Text Block]	Revenue Recognition On January 1, 2018, we adopted accounting standard ASC 606, Revenue from Contracts with Customers and all the related amendments using the modified retrospective method for all customer contracts not yet completed as of the adoption date. Results for reporting periods beginning January 1, 2018 are presented under ASC 606, while prior period amounts were not adjusted. The adoption of ASC 606 did not have a significant impact on our Consolidated Financial Statements as of and for the three and six month periods ended June 30, 2018 and, as a result, comparisons of revenues and operating profits performance between periods are not affected by the adoption of this ASU. The Company designs, manufactures and sells custom chemical vapor deposition equipment through contractual agreements. These system sales require the Company to deliver functioning equipment that is generally completed within three to eighteen months from commencement of order acceptance. The Company recognizes revenue over time by using an input method based on costs incurred as it depicts the Company’s progress toward satisfaction of the performance obligation. Under this method, revenue arising from fixed price contracts is recognized as work is performed based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligations. Incurred costs include all direct material and labor costs and those indirect costs related to contract performance, such as indirect labor, supplies, tools, repairs and depreciation costs. Contract material costs are included in incurred costs when the project materials have been purchased or moved to work in process as required by the project’s engineering design. Cost based input methods of revenue recognition require the Company to make estimates of costs to complete the projects. In making such estimates, significant judgment is required to evaluate assumptions related to the costs to complete the projects, including materials, labor and other system costs. If the estimated total costs on any contract are greater than the net contract revenues, the Company recognizes the entire estimated loss in the period the loss becomes known and can be reasonably estimated. “Contract assets,” include unbilled amounts typically resulting from sales under contracts when revenue recognition is utilized and revenue recognized exceeds the amount billed to the customer. The amount may not exceed their estimated net realizable value. Contract assets are classified as current based on our contract operating cycle. “Contract liabilities,” include advance payments and billings in excess of revenue recognized. Contract liabilities are classified as current based on our contract operating cycle and reported on a contract-by-contract basis, net of revenue recognized, at the end of each reporting period. For outright sales of products, revenue is recognized when control of the promised products or services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those products or services (the transaction price). A performance obligation is a promise in a contract to transfer a distinct product or service to a customer and is the unit of account under ASC 606.
Research and Development Expense, Policy [Policy Text Block]	Research and Development Research and development costs are expensed as incurred. Due to the highly technical nature of our projects, we use our technical staff in a dual role, and based on their contribution to the customer or research and development projects, their costs are charged accordingly to either cost of goods sold or research and development.
New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Pronouncements In June 2016, the FASB issued ASU 2016 - 13, F inancial Instruments – Credit Losses (Topic 326 ) , which require that financial assets measured at amortized cost be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset to present the net carrying value at the amount expected to be collected. The income statement reflects the measurement of credit losses for newly recognized financial assets, as well as the increase or decreases of expected credit losses that have taken place during the period. The measurement of expected credit losses is based upon historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. The amendments in this update are effective for fiscal years beginning after December 15, 2019 and interim periods within those annual periods. Early adoption for fiscal years beginning after December 15, 2018 is permitted. We are currently evaluating the effect of this update on our consolidated financial statements. Recently Adopted Accounting Pronouncements In February 2016 the FASB issued ASU No. 2016 - 02, "Leases (Topic 842 )" (ASU 2016 - 02 ). The primary difference between previous GAAP and ASU 2016 - 02 is the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous GAAP. The guidance requires a lessee to recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. When measuring assets and liabilities arising from a lease, a lessee (and a lessor) should include payments to be made in optional periods only if the lessee is reasonably certain to exercise an option to extend the lease or not to exercise an option to terminate the lease. Similarly, optional payments to purchase the underlying asset should be included in the measurement of lease assets and lease liabilities only if the lessee is reasonably certain to exercise that purchase option. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. If a lessee makes this election, it should recognize lease expense for such leases generally on a straight-line basis over the lease term. ASU 2016 - 02 is effective for fiscal years beginning after December 15, 2018. Lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The modified retrospective approach includes a number of optional practical expedients that entities may elect to apply. An entity that elects to apply the practical expedients will, in effect, continue to account for leases that commence before the effective date in accordance with previous GAAP unless the lease is modified, except that lessees are required to recognize a right-of-use asset and a lease liability for all operating leases at each reporting date based on the present value of the remaining minimum rental payments that were tracked and disclosed under previous GAAP. In addition, FASB has amended Topic 842 prior to it becoming effective. The effective date and transition requirements for these amendments to Topic 842 are the same as ASU 2016 - 02. The Company has one lease at its Denmark facility which currently expires at December 31, 2020 and has recognized a lease liability and a right-of-use asset representing its right to use the underlying asset for the lease term in the amount of $129,000 . We believe there is no additional new accounting guidance adopted, but not yet effective that is relevant to the readers of our financial statements. However, there are numerous new proposals under development which, if and when enacted, may have a significant impact on our financial reporting.
