Inventories [Abstract]
Inventories	2. Inventories: With the sale of the DRIE product line, the Company no longer has inventory or inventory provisions. Until February 9, 2011, inventories were stated at the lower of cost or market. Cost is computed using standard cost, which approximates actual cost on a first-in, first-out basis and includes material, labor and manufacturing overhead costs. Any excess and obsolete provision is only released if and when the related inventory is sold or scrapped.

The entire disclosure for inventory. This may include, but is not limited to, the basis of stating inventory, the method of determining inventory cost, the major classes of inventory, and the nature of the cost elements included in inventory. If inventory is stated above cost, accrued net losses on firm purchase commitments for inventory and losses resulting from valuing inventory at the lower-of-cost-or-market may also be included. For LIFO inventory, may disclose the amount and basis for determining the excess of replacement or current cost over stated LIFO value and the effects of a LIFO quantities liquidation that impacts net income.
