Title: Production of optical element
Inventor: UMETANI MAKOTO
IPC: C03B11/00
Filed: 1987-08-25
Abstract: PURPOSE:To contrive improvement in accuracy and mass-productivity of products, by carrying out pressing in a mold having metallic tantalum formed on a pressing surface. CONSTITUTION:A pair of upper and lower pressing forces of a super hard alloy base metal 12 consisting essentially of WC are machined and mirror finishing is carried out by superfine grinding. The mirror surface is then coated with an ultrathin Ta film 11 by a sputtering method, etc., to provide a pressing mold. Alternatively, a recessed surface shape is formed by using metallic Ta 21 to form a pair of upper and lower pressing forces. These pressing forces are used as the top and bottom forces, set in a press to hot-press an optical glass in a state machined into a spherical form between both forces in nitrogen atmosphere, etc., and carry out pressing. In the process, since the metallic Ta itself or Ta metal thin film is present in the pressing surface, reaction with the glass element is prevented. Thereby accuracy and mass-productivity of the products are improved.

CONSTITUTION:A loop 34 of circulating-oil on the side of low temperature is composed of an injection pump 28, an oil-sending pipe 30, an injection nozzle 20, a cyclone 22, an oil basin 24, an oil-lowering pipe line 26 and a heat exchanger 15 for absorbing heat, and code heat by heat-absorbing action is used. A loop 35 of the circulating oil on the side of high temperature is composed of an injection pump 29, an injection nozzle 21, a cyclone 23, an oil basin 25, an oil-lowering pipe line 27, a heat exchanger 17 for radiating heat and an oil-sending pipe 31, and heat-radiating action is performed. At each of the injection pumps 28, 29, the circulating oil having such the amount as a thermal equivalent of the circulating oil injected is about 5 to 10 times as many as a thermal equivalent, per unit time, of working- gas such as high pressure helium which is sucked or exhausted in an expansion space 11 and a compression space 12, is injected. The expansion and compression of the working gas, which are performed in the expansion space 11 and the compression space 12, make slow the temperature change of the working gas since the liquid drops of the circulating oil exist. Therefore, the expansion and compression approaching to isothermal change are performed, and the working gas performs an approximate isothermal change approaching to the theory of reverse Stirling cycle.

IPC: G11C11/403
Filed: 1993-08-26
Abstract: PURPOSE:To realize an initial-stage circuit of low power consumption without lowering in a specific mode the initial-stage circuit characteristics in a regular mode and with stability, by providing two kinds of initial-stage circuits different in the characteristics and by limiting activation of each of them. CONSTITUTION:As initial-stage circuits, a current mirror type one for regular high-speed operations and a complementary logic type one of which the power consumption decreases at the time of input are used. Since low power consumption is required in a self-refresh mode, an internal operation for canceling the self-refresh mode or activating the current mirror type initial-stage circuit on the basis of a change from a CMOS level of a CKE input level brought forth on or before the cancellation of this mode to an output level on a small- amplitude interface is made to be assigned to the complementary logic type initial-stage circuit of which the power consumption is low. According to this constitution, a self-refresh operation can be executed with low power consumption even when the current mirror type circuit corresponding to the high-speed small-amplitude interface is used in an initial stage of input.
