Investments Debt And Equity Securities [Abstract]	'
Marketable Securities	'
	Note 2 – Marketable Securities
	Marketable debt and equity securities are categorized as trading securities and are thus marked to market and stated at fair value. Fair value is determined using the quoted closing or latest bid prices for Level 1 investments and market standard valuation methodologies for Level 2 investments. Realized gains and losses on investment transactions are determined by specific identification and are recognized as incurred in the statements of operations. Net unrealized gains and losses are reported in the statements of operations in the current period and represent the change in the fair value of investment holdings during the period.
	Fair Value Measurements
	The fair value of financial instruments is presented based upon a hierarchy of levels that prioritizes the inputs of valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.
	The fair value of marketable equity securities and mutual funds are substantially based on quoted market prices (Level 1). Corporate and municipal bonds are valued using market standard valuation methodologies including: discounted cash flow methodologies, matrix pricing or other similar techniques. The inputs to these market standard valuation methodologies include, but are not limited to: interest rates, credit standing of the issuer or counterparty, industry sector of the issuer, coupon rate, call provisions, maturity, estimated duration and assumptions regarding liquidity and estimated future cash flows. In addition to bond characteristics, the valuation methodologies incorporate market data, such as actual trades completed, bids and actual dealer quotes, where such information is available. Accordingly, the estimated fair values are based on available market information and judgments about financial instruments (Level 2). Fair values of the Level 2 investments are provided by the Company’s professional investment management firm.
	The following tables set forth, by level, within the fair value hierarchy, the Company’s assets measured at fair value as of December 31, 2013:
		Fair Value Measurements

There were no transfers of investments between Level 1 and Level 2 during the quarter ended December 31, 2013.

Estimated interest accrued on the corporate and municipal bond portfolio was $399,000 at September 30, 2013. There were no transfers of investments between Level 1 and Level 2 during the quarter ended December 31, 2012.
	The carrying amounts of cash and cash equivalents, accounts receivable and accounts payable approximate fair value because of the short-term nature of these items.

Inventories	'
	Note 3 – Inventories
	Inventories are valued at the lower of cost or market, with cost being determined principally by using the last-in, first-out (“LIFO”) method and market defined as replacement cost for raw materials and net realizable value for work in process and finished goods. Appropriate consideration is given to obsolescence, excessive levels, deterioration, possible alternative uses and other factors in determining net realizable value. The cost of work in process and finished goods includes materials, direct labor, variable costs and overhead. The Company evaluates the need to record inventory allowances on all inventories including raw material, work in process, finished goods, spare parts and used equipment. Used equipment acquired by the Company on trade-in from customers is carried at estimated net realizable value. Unless specific circumstances warrant different treatment regarding inventory obsolescence, the cost basis of inventories three to four years old is reduced by 50% while the cost basis of inventories four to five years old is reduced by 75% and the cost basis of inventories greater than five years old is reduced to zero. Inventory is typically reviewed for obsolescence on an annual basis computed as of September 30th, the Company’s fiscal year end. If significant known changes in trends, technology or other specific circumstances that warrant consideration occur during the year, then the impact on obsolescence is considered at that time.
	Net inventories at December 31, 2013 and September 30, 2013 consist of the following:
		December 31, 2013		September 30, 2013
	Raw materials	$	5,207,000	$	6,238,000
