Title: Preparation method of electrolyte for alkaline battery
Inventor: TSUZUKI SHUSUKE
IPC: H01M6/06
Filed: 1994-05-12
Abstract: PURPOSE:To enhance the electrolyte leakage resistance of an alkaline battery. CONSTITUTION:A KOH solution is stored in a stainless steel tank 1. While the KOH solution in the tank 1 is stirred with a blade 2 and a motor 3, nitrogen gas is introduced into the KOH solution from a supply pipe 4 with a pump 5 to make the inside of the tank 1 in the inert atmosphere. In this state, ZnO is heat-dissolved in the KOH solution in the tank 1. Since an electrolyte for an alkaline battery is prepared in the nitrogen gas atmosphere, oxidation reaction of stainless steel which is the material of the tank 1 is not advanced, and since nitrogen gas is introduced into the KOH solution while it is stirred, active gas such as oxygen is replaced with inert nitrogen gas. As a result, hydrogen gas generation in the alkaline battery is reduced, and electrolyte leakage of the alkaline battery caused by increase in internal pressure is prevented.

Abstract: PURPOSE:To prevent a resin bush from being displaced and falling off further to improve wearing and friction characteristics, by providing a squared type annular groove in the peripheral surface of a piston metal fixture and mounting the resin bush, which is mainly composed of polytetrafluoroethylene combining 10-25% carbon dust, to be fitted to said annular groove. CONSTITUTION:A squared type annular groove 3 is provided in a piston metal fixture 1, and a piston, in which a resin bush 2 is mounted to said annular groove, is built in a strut. Here the resin bush 2 uses a material which is mainly composed of polytetrafluoroethylene combining 10-25% carbon dust in a charging range because the material large wears for 10% or less while provides a large wearing coefficient for 25% or more. As the result, a dynamic friction coefficient is equivalent as compared with a material of 15% graphite conventionally used as a resin bush material, but the above material is excellent in wearing resistance.

Abstract: PURPOSE:To reduce a switching noise caused by the stray capacitance between the windings of the primary side and secondary side of a transformer by giving a potential for generating an electric field for canceling the switching noise to electrostatic shielding provided between the primary and secondary windings of the transformer. CONSTITUTION:A voltage divider circuit composed of the series circuit of resistors R1 and R2 is connected between both ends A, C of the secondary winding 7 of a transformer 2 and the voltage divider point of the circuit is connected with electrostatic shielding 6.

Further, the voltage divider ratio of the voltage divider circuit is determined so that a switching noise is minimized, while the voltages of the primary side and secondary side are observed. Thus, it is possible to obtain a switching power supply in which the switching noise caused by the stray capacitance between the windings of the primary side and secondary side of the transformer is reduced.

Abstract: PROBLEM TO BE SOLVED: To wholly change nonpolarized light emitted from a light source into identical linearly polarized light and to uniformly illuminate the whole objective area by using a thin plate type device having both flat front and back faces as a polarizing separating device. SOLUTION: A first cholesteric liquid crystal device 16 is a thin plate type device having both flat front and back faces. Nonpolarized light from a reflector 12 transmitted through a first lens array 14 is separated into the reflected light which is right-handed circularly polarized light and the transmitted light which is left-handed circularly polarized light. The light transmitted through the first cholesteric liquid crystal device 16 enters a second cholesteric liquid crystal device 17. The cholesteric liquid crystal device 17 is also a thin plate type and it reflects the left-handed circularly polarized light and transmits the right- handed circularly polarized light.  Therefore, the optical paths of the light reflected by the cholesteric liquid crystal device 16 and the optical paths of the light reflected by the cholesteric liquid crystal device 17 are alternately distributed at an almost equal interval.
