Title: Floating-point arithmetic unit
Inventor: WATANABE TAKESHI
IPC: G06F7/508
Filed: 1985-06-10
Abstract: PURPOSE:To make the arithmetic result of zero at a high speed by providing a means which generates the zero condition of a fixed-point part in accordance with the exponent part of an intermediate result and the fixed-point part of the intermediate result independently of a means which detects the exponent underflow exception. CONSTITUTION:In a mantissa normalization arithmetic part 18, zero bits of an intermediate result register 6 are encoded by an encoder 11' to obtain a normalized counted value, and this normalized counted value is subtracted from the exponent part of an intermediate result register 8 to obtain the zero condition of the fixed-point part by a carry look ahead forecasting circuit 19. If the zero condition is satisfied, the output (zero signal) of the circuit 19 goes to '1', and the arithmetic result of the fixed-point part obtained by a normalization shift circuit 10 is made of zero by an AND circuit 14. Thus, the arithmetic result is made of zero at a high speed evenn if the exponent under-flow exception occurs.

IPC: C23C16/00
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To enable the precision reproduction of a dimensionally exact article consisting of dense material by forming the opposite surface of the article on a substrate surface and applying a peelable coating adhered to the substrate surface at the time of taking the material out of the substrate onto the substrate surface. SOLUTION: The zinc sulfide article is produced in a furnace 10. A part or the whole of the inner side surface of a square mandrel 16 consists of a zinc sulfide sheet having the surface machined to an RMS surface roughness below half of the wavelength (632.8 nm) by an He-Ne laser and is coated with an alumina layer of a thickness of about 2000 to 3000 Å. The coating is executed by sputtering, physical vapor deposition, such as evaporation, or a process utilizing a plasma. The accuracy and finish of a coated mandrel 16 are measured and, if the accuracy and finish are not in a regulated range, this coating is stripped and, if necessary, the bare mandrel 16 is polished again and is subjected to the coating again.

Title: Metal-bromine cell of static electrolyte type
Inventor: HASHIMOTO TAKASHI
IPC: H01M12/08
Filed: 1990-05-15
Abstract: PURPOSE:To prevent energy emitted from being lowered by disposing carbon cloth in a positive electrode chamber in such a manner as being opposed and joined to the reaction face of a positive electrode. CONSTITUTION:A positive electrode chamber is formed by sequentially stacking a carbon plastic electrode 1, carbon cloth 2, and a porous separator plate 3. A negative electrode chamber comprises a supporter net 5 interposed between the separator plate 3 and a carbon plastic electrode 4 disposed opposite to and at a fixed distance to the separator plate 3 and is sealed at its periphery against heat by a frame 6 of polyethylene resin together with the positive electrode chamber to form a cell main body. The positive and negative electrode chambers of the cell main body thus formed are independently filled with an electrolyte of zinc bromide (Zn Br2). Even in this zinc-bromine cell of static electrolyte type, bromine generated at the positive electrode and its complex compounds are not accumulated on the bottom of the positive electrode chamber but attached and held on the carbon cloth 2 so the reaction area of the positive electrode will not be reduced. A high-efficiency cell is thus obtained without lowering its electric energy.

Title: Semiconductor memory device
Inventor: SHIMURA HIDEYOSHI
IPC: G11C29/04
Filed: 1980-09-09
Abstract: PURPOSE:To realize the high-degree relief of defects and to increase the yield of a semiconductor memory, by selectively decoding the redundant memory region with an output of coincidence with an address that specifies the defective block of a main memory. CONSTITUTION:When a coincidence is obtained between the fixed addresses of circuits 25 and 25 that fix the address information in the main memory block region where a defective memory cell exists and a prescribed low address signal in the address signal, the outputs of coincidence circuits 22 and 22 are inverted to a high level, respectively. The outputs of coincidence of these circuits 22 and 22 are decoded, and accordingly no access is given to the defective memory and the main memory block. The block corresponding to a redundant memory receives an access to relieve even the defects of two blocks. If the number of circuits 22 is more increased, the relief is possible even for the defects of several bits in group. In such way, the high-degree relief is possible to increase the yield of a semiconductor memory.

Title: Laser beam scanning device
Inventor: WADA TOSHIYUKI
IPC: B41J2/44
Filed: 1992-05-19
Abstract: PURPOSE:To obtain a laser scanning device of which writing error is small because of being hardly affected by a noise from outside by amplifying the output of a detector detecting the scanning starting position of a laser beam. CONSTITUTION:When the laser beam is made incident, voltage outputted from a PIN photodiode 1 is amplified by a transistor 2 for next amplification. The amplified signal is inputted to a comparator 5 and waveshaped. When the scanning laser starts being incident to the PIN photodiode 1, the rising waveform of voltage is outputted in accordance with the light quantity. By amplifying the voltage signal, the rising waveform is made steep to make the error of the waveform caused by the noise to be small. Thus, when the comparator 5 wave-forms the signal to set it to be the detection signal of writing, writing error caused by the noise can be made small.
