Title: Manufacture of conductive binding agent and application top various kinds of batteries
Inventor: OZAWA AKIHISA
IPC: H01M4/62
Filed: 1991-10-31
Abstract: PURPOSE:To provide an electrode for a cell and a battery, which is excellent in charge/discharge performance by uniformly dispersing fluorine resin and carbon material in solution, removing the solution so as to allow composite material to be produced thereafter, and thereby binding electrode active material using the aforesaid composite material as binding agent. CONSTITUTION:Fluorine resin powder and carbon material such as Ketien black whose grain size is less than 0.1mum are dispersed in the class of alcohol such as methanol and the like and the class of halide alkyl such as acetonitrile and the like, are mechanically stirred and dispersed uniformly so as to be formed into composite material, so that the solution is removed thereafter. The composite material thus produced has two properties of binding performance and conductivity, so that electrode active material can be bound without lowering conductivity. The carbon material is high in oxygen over potential, a battery with nickel oxide electrodes can sufficiently be charged with less self-discharge and with performance scarcely deteriorated. The carbon material is therefore effective in particular as the binding material for the positive electrode when aqueous solution is used as electrolytic solution.

Title: Coupler mounting mechanism of motorcycle
Inventor: KATAYAMA MUTSUMI
IPC: B60R16/02
Filed: 1993-12-28
Abstract: PURPOSE:To see that electrolytic corrosion does not occur by attaching a coupler to the car body so that the terminal always maintained at positive potential may not be lower at all times than those of other plural terminals arranged on the coupling face of a coupler. CONSTITUTION:A regulator rectifier 30 is attached, aslant to the vertical axis A-A' of the body, to a bracket 20, and when the car body is in vertical posture, the regulator rectifier 30 is slant at angle shown by the center line B-B' (the direction of coupling of a coupler) Accordingly by this tilt of the regulator rectifier 30, the terminal maintained at positive potential is in the position equal to or higher than other terminal arranged at the coupling face between the coupler on the regulator rectifier 30 side and the coupler on the opposite side. Therefore, the water collected at the terminal part stays on the terminal on lower side. Hereby, the terminal at positive potential is hardly soaked in water, therefore corrosion does not occur.

Title: Reciprocating optical amplifier
Inventor: YAMAMOTO SHUHEI
IPC: H01S3/16
Filed: 1998-12-09
Abstract: PROBLEM TO BE SOLVED: To enhance the amplification factor while stabilizing the output light by employing two concave lenses of identical focal length disposed on the outside of two optical amplifying means as a heat lens compensating means, thereby suppressing the wave aberration or astigmatism of laser light. SOLUTION: Since solid-state laser rods (optical amplifying means) 2-1, 2-2 generate heat by absorbing pumping light, in general, they are cooled from the side face side. Consequently, the temperature at the side face side decreases but the temperature increases in the cross-sectional central part of the solid laser rods 2-1, 2-2. Thus when the solid-state laser rods 2-1, 2-2 are composed of an isotropic medium, e.g. Nd:YAG, the solid-state laser rods 2-1, 2-2 serve as convex lens for laser light and heat lens effect is obtained. Spread of laser light is thereby compensated by arranging a concave lens 7, as a heat lens compensating means, on the optical axis.
