Accounting Policies [Abstract]
Business Description	NOTE 1: BUSINESS DESCRIPTION The Company was incorporated in New York on March 21, 1975 for the purpose of engaging in the development, manufacture, and sale of ultrasonic liquid atomizing nozzles, which are sold world-wide. Ultrasonic nozzle systems atomize low to medium viscosity liquids by converting electrical energy into mechanical motion in the form of high frequency ultrasonic vibrations that break liquids into minute drops that can be applied to surfaces at low velocity. Based on its core technology of ultrasonic liquid atomizing nozzles, the Company has developed intellectual property in the area of precision spray coating of liquids. The Company is presently engaged in the development, manufacture, sales, installation and servicing of diverse ultrasonic coating equipment for various manufacturing industries worldwide.

Significant Accounting Policies	NOTE 2: SIGNIFICANT ACCOUNTING POLICIES Available-For-Sale Investments – Cash and Cash Equivalents - Consolidation Earnings Per Share - Equipment, Furnishings and Leasehold Improvements Fair Value of Financial Instruments - Level 1: Quoted prices in active markets. Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data. Level 3: Unobservable inputs for which there is little or no market data, which require the use of the reporting entity’s own assumptions. The fair values of financial assets of the Company were determined using the following categories at November 30, 2016 and February 29, 2016, respectively: Quoted Prices in Active Markets (Level 1) November 30, February 29, Marketable Securities $ 2,067,874 $ 1,695,689 Marketable Securities include mutual funds of $2,067,874 and $1,695,689 that are considered to be highly liquid and easily tradeable as of November 30, 2016 and February 29, 2016, respectively. These securities are valued using inputs observable in active markets for identical securities and are therefore classified as Level 1 within the Company’s fair value hierarchy. The Company’s marketable securities are considered to be available-for-sale investments as defined under ASC 320 “Investments – Debt and Equity Securities.” Income Taxes Intangible Assets - Interim Reporting The financial information reflects all adjustments, normal and recurring, which, in the opinion of management, are necessary for a fair presentation of the results for the interim periods presented. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The results for such interim periods are not necessarily indicative of the results to be expected for the year.

Stock Options and Warrants	NOTE 4: STOCK OPTIONS AND WARRANTS Stock Options Under the 2003 Stock Incentive Plan, as amended ("2003 Plan"), until May 2013, options were available to be granted to officers, directors, consultants and employees of the Company and its subsidiaries to purchase up to 1,500,000 shares of the Company's common stock. As of November 30, 2016, there were 198,000 options outstanding under the 2003 Plan, under which no additional options may be granted.

Stock Based Compensation

Stock Based Compensation	9 Months Ended

Stock Based Compensation	NOTE 5: STOCK BASED COMPENSATION The weighted-average fair value of options are estimated on the date of grant using the Black-Scholes options-pricing model. In computing the impact, the fair value of each option is estimated on the date of grant based on the Black-Scholes options-pricing model utilizing certain assumptions for a risk free interest rate; volatility; and expected remaining lives of the awards. The assumptions used in calculating the fair value of share-based payment awards represent management’s best estimates, but these estimates involve inherent uncertainties and the application of management judgment. As a result, if factors change and the Company uses different assumptions, the Company’s stock-based compensation expense could be materially different in the future. In addition, the Company is required to estimate the expected forfeiture rate and only recognize expense for those shares expected to vest. In estimating the Company’s forfeiture rate, the Company analyzed its historical forfeiture rate, the remaining lives of unvested options, and the number of vested options as a percentage of total options outstanding. If the Company’s actual forfeiture rate is materially different from its estimate, or if the Company reevaluates the forfeiture rate in the future, the stock-based compensation expense could be significantly different from what the Company has recorded in the current period. For the nine months ended November 30, 2016 and 2015, net income and earnings per share reflect the actual deduction for stock-based compensation expense. The impact of applying ASC 718 approximated $34,000 in additional compensation expense during each of the nine month periods ended November 30, 2016 and 2015. Such amounts are included in general and administrative expenses on the statement of operations. The expense for stock-based compensation is a non-cash expense item.

Other Comprehensive Income (Loss)	NOTE 7: OTHER COMPREHENSIVE INCOME (LOSS) As of November 30, 2016, certain of the Company’s marketable securities were in an unrealized loss position. Unrealized gains and losses are principally due to changes in fair value of the investments held as available-for-sale. The Company has the ability and intent to hold the securities until maturity, or for the foreseeable future as classified as available-for-sale. The Company does not deem these unrealized gains or losses to be other than temporary. As of November 30, 2016, the unrealized loss on available-for-sale securities was $9,043. The following table sets forth the changes in Accumulated Other Comprehensive Gain (Loss) for the nine months ended November 30, 2016: Unrealized Gain (Loss) on Available for Sale Securities Beginning Balance February 29, 2016 $ (70,140 ) Current Period Unrealized Gains 61,097 Ending Balance November 30, 2016 $ (9,043 )
