Title: Sealed type lead storage battery
Inventor: TANI YOSHIHITO
IPC: H01M50/437
Filed: 1987-05-26
Abstract: PURPOSE:To prevent the reduction of the reaction area due to the poor adhesion with an electrode plate by containing sodium sulfate anhydride as the binder of a retainer. CONSTITUTION:An electrode plate group grouped with electrode plates 4 covered with a retainer 3' containing sodium sulfate anhydride as a binder is used. The sodium sulfate anhydride serving as the binder of the retainer 3' covers the positive electrode plate 4, the electrode plates are grouped into the electrode plate group to assemble an enclosed type lead storage battery. When an electrolyte is injected, the sodium sulfate anhydride is melted in the electrolyte, and the retainer is converted into one made of only glass fibers. The converted retainer thereby abounds in adherence with the positive electrode plates 4 and negative electrode plates in the electrode plate group, and the falling of the active material can be suppressed.

Title: Manufacture of semiconductor device
Inventor: UCHIDA TETSUYA
IPC: H01L21/768
Filed: 1999-05-10
Abstract: PROBLEM TO BE SOLVED: To obtain a method of manufacturing a semiconductor device by which good junction reverse bias characteristics can be obtained without increasing leakage current between the N-diffusion layer forming the source and drain constituting a MOS transistor and the P well, even in a case where pattern displacement arises between contact pads and a device separation oxide film when a pattern of contact pads for contact of a diffusion layer is formed for reducing the area of memory cells such as DRAM. SOLUTION: Even if a part of an N-diffusion layer 6 is overetched and the P well 1 is exposed due to pattern displacement of contact pads, no etching damage is left on the border between the N-diffusion layer 6 and the P well 1, since the exposed surface is covered with an N-diffusion layer 11 by ion implantation or solid phase diffusion of phosphorus. Therefore, increase in leak between the N-diffusion layer and the P well can be prevented and good junction reverse bias characteristics can be maintained.

Filed: 1984-06-25
Abstract: PURPOSE:To enhance the effect of heat radiation, by placing an RTV rubber of high thermal conductivity as a filler between a heat radiating plate and a metal band wound around the faceplate of a cathode-ray tube. CONSTITUTION:An X-ray shield 7 made of metal is provided around the faceplate 1 of a cathode-ray tube in order to block X-rays. The tube is reinforced by a metal band 6 for preventing the glass of the tube from scattering away at the time of bursting and compression of the tube. An RTV rubber 8 of high thermal conductivity is placed as a filler between a heat radiating plate 4 and one or both of the metal band 6 and the X-ray shield 7 so that the plate 4, the band 6 and the shield 7 are thermally connected to each other. As a result, the band 6 and the shield 7 can function to radiate heat so that the fluorescent faceplate 1 cannot crack even if an electron beam of higher energy than with the radiation of heat only by the heat radiating plate 4 is projected to the faceplate. For that reason, a high-luminance image can be made.

IPC: D21C11/00
Filed: 1978-10-20
Abstract: PURPOSE: To reduce the amount of sludge by using effectively coagulant by the procedure in which a soluble ferrous salt is used as a coagulant in the treatment of pulp mill waste water by a coagulating sedimentation method and then recovered from formed sludge for reuse.  
     CONSTITUTION: A soluble ferrous salt, e.g., ferrous sulfate, ferrous chloride, etc., and an alkali, e.g., a hydroxide, carbonate, etc., of Na, K, Ca, etc., are added to the pulp mill waste water for a coagulating sedimentation treatemnt, and then formed sludge is separated from supernatant by a sedimenting separation method.

Title: Automatic control circuit of servo gain
Inventor: MINAMI AKIRA
IPC: G11B7/09
Filed: 1983-07-15
Abstract: PURPOSE:To obtain a stable driving output of an optical head in both reproduction and recording modes regardless of variation of the total reflected light quantity, by providing a changeover switch which switches the gains of both amplifiers with switch signals of recording and reproduction modes and a control means which stabilizes the outputs of both amplifiers approximately at the same level regardless of a recording or reproduction mode. CONSTITUTION:The servo gain is decided by amplifiers 2 and 3, and the gain of the amplifier 3 is decided from the equivalent drain-source resistance value of an FET4 as well as resistances R18 and R19. Then the gain of the amplifier is decided based on the mean value of laser power of a recording mode. Thus the servo gain is liable to have a shortage despite the gain setting of an amplifier 16 since the level of the laser power is low in a reproduction mode. In this respect, an analog switch 14 is controlled by a recording/reproduction gate to obtain the drive voltage approximately equal between recording and reproduction modes in order to compensate a track shift. For this purpose, the values of resistances R18 and R19 are properly selected. In such a way, the optimum servo gain is obtained.
