Title: Production of cover for camera made of titanium alloy
Inventor: TSUJII HIDEKI
IPC: B21D22/26
Filed: 1995-06-27
Abstract: PURPOSE: To form a cover for camera made of titanium alloy, which is not formed in a conventional way, by forming with plural drawing processes in which each drawing ratio is increased at every process stepwise and executing solution heat treatment before each drawing process. CONSTITUTION: By forming a chemically treated film of phosphate, etc., on the sheet surface of β titanium alloy and improving lubricity of surface, galling prevention is executed. By executing drawing with a die 1 and then subjecting to solution heat treatment, the alloy structure subjected to work-hardening due to forming is returned to the original state and drawability is restored. Drawing is executed by the die 2 in which its drawing ratio is made larger than the die 1. While solution heat treatment is executed in the meantime, drawings are executed by dies with increasing its drawing ratio stepwise. After an objective shape is worked, age hardening or precipitation hardening is executed. By this method, a cover for camera, in which β titanium alloy having strength larger than pure titanium is used for stock, is formed.

Title: Multiplier circuit
Inventor: OOTA SHINGO
IPC: G06F7/00
Filed: 1984-07-30
Abstract: PURPOSE:To carry out the multiplication of 2<n> floating decimal points at a high speed by using simple hardware constitution consisting of a control signal generation means, an exponent part arithmetic means containing a normalization correcting function and a mantissa part arithmetic means containing a shift function. CONSTITUTION:When the multiplication of 2<5>, for example, is carried out, ''000000101'' is stored in a multiplication register 110. A control signal producing part 130 produces an exponent part correction signal for addition of 0 and a mantissa part shift signal for left shift by a bit from low-order two bits ''01'' of the register 110 and low-order four bits ''0010'' of the mantissa part data of a multiplicand register 120. At the same time, an exponent part adder 240 of an exponent part arithmetic means 140 adds high-order seven bits of the register 110 with seven bits of the exponent part of the register 120. Here the means 140 produces seven bits of a normalized exponent part by the correction signals. While a mantissa part shifter part 150 produces a normalized mantissa part by the maintissa part shift signal. Then the result of the 2<n> multiplication is stored in a register 160.

IPC: F16K31/68
Filed: 1981-10-12
Abstract: PURPOSE:To prevent an engine from knocking in the means for controlling the temperature at which a valve is to be opened, is accordance with the engine  load by quickly opening the valve at a specific point when the engine load is  shifted to high so as to reduce the temperature of cooling water. CONSTITUTION:Cooling water to be supplied to an engine is controlled by a thermostat valve 7, which is adjusted via a diaphragm device 11 and a negative pressure delay valve 16 on the basis of a suction negative pressure corresponding to the engine load. When the engine load is shifted to a high value, with a negative pressure at the side of a negative pressure passage 33 lower than the negative pressure in a negative pressure chamber 14, a one-way valve 30 is opened. Since the negative pressure in the negative pressure chamber 14 quickly rises close to the negative pressure at the side of the negative pressure passage 33, a timing at which the thermostat valve 7 is opened may be advanced to quickly reduce the temperature of cooling water to a low value.
