Title: Zinc alkaline primary battery
Inventor: MIURA AKIRA
IPC: H01M4/06
Filed: 1984-02-23
Abstract: PURPOSE:To greatly reduce the amalgamation rate of the negative zinc active material without deteriorating the storage performance and the liquid leakage resistance of a zinc alkaline primary battery by fixing at least one element selected from among thallium, gallium and silver to the surfaces of particles of a zinc alloy containing specified elements. CONSTITUTION:After a zinc alloy principally composed of zinc and containing at least one element selected from among lead, cadmium and tin is pulverized, the thus formed particles are coated with at least one element selected from among thallium, gallium and silver. After that, at least the element covering the surfaces of the particles is amalgamated, thereby preparing a negative active material for a zinc alkali battery. The thus prepared negative active material does not change with the passing of time and a concentration of mercury in the surfaces of the particles necessary to secure their corrosion resistance is maintained. Furthermore, the amalgamation rate of the inner areas of the zinc alloy particles is maintained at a very low level.

Filed: 1988-02-17
Abstract: PURPOSE:To enhance the heat generating efficiency of a current supply recording head, by providing a groove to the midway part of an electrode so that the midway cross-sectional area of the electrode is reduced as compared with the area of the current supply surface of a recording electrode. CONSTITUTION:Recording paper 10 and a current supply transfer sheet 9 are superposed to be held between a platen and a current supply recording head 5 and, when voltage is applied between recording electrodes 1 and a return electrode 11, a current flows to the return electrode 11 through a current supply heat generating layer 8 and conductive layer 7. In this current supply route, Joule heat is generated in the current supply heat generating layer 8 highest in resistance and the sublimable dye in a colorant layer 6 is sublimed to be transferred to the recording paper 10 to form an image. Electrode grooves 4 are simultaneously formed to all of recording electrodes at a predetermined position from the current supply surfaces 3 of the recording electrodes 1 to reduce the total cross-sectional area of the recording electrodes 1 to 1/6. By reducing the cross-sectional area to 1/6, heat transfer resistance becomes 6 times and the escape of heat from the current supply surface 3 is stopped at the groove parts and the quantity of the heat conducted to the colorant layer on the surface of the sheet increases and the recording efficiency of heat to the supply quantity of a current is enhanced. The grooves are formed to a plurality of the electrodes by simultaneous processing and the irregularity of the distance of each of the grooves from the current supply surfaces and the width and depth of each of the grooves between the electrodes can be reduced.

Abstract: PURPOSE:To improve the tone margin at low and high frequencies by using a flat circuit provided at the input side of an echo canceller so as to make the spectrum of an input signal flat and smoothing the difference between the signal at the output terminal and the input signal. CONSTITUTION:When an echo comes to an outgoing channel W in a 2/4-wire converter 2B, the echo signal is given to a half wave rectifier circuit 5B, where the frequency spectrum is made flat and the result is inputted to a transmission input terminal Sin of the echo canceller 7B. On the other hand, since a signal smoothing the spectrum is fed similarly to a reception input terminal Rin of the echo canceller 7B, the echo canceller 7B applies echo elimination over the entire frequency of the echo signal as shown in an Sout signal. The similar operation is applied as to the signal inputted from a 2-wire input terminal 1B.

Title: Production of laminate
Inventor: OGATA MASARU
IPC: C08J5/24
Filed: 1986-02-19
Abstract: PURPOSE:To obtain a phenol resin laminate controlled in silver migration and excelling in electrical properties, by performing laminate-molding after laying one prepreg formed by impregnating a base with an oil-modified phenolic resin varnish containing an epoxy resin and drying the base on the outermost surface. CONSTITUTION:In producing a laminate by laminate-molding prepregs obtained by undercoating a paper base with a water-soluble phenolic resin, impregnating the base with an oil-modified phenolic resin and drying it, said laminate molding is performed by laying one prepreg obtained by impregnating a base with a varnish obtained by adding 10-50wt% (in terms of solid matter) epoxy resin to the oil-modified phenolic resin and drying it on the outermost surface. Because the obtained laminate has a layer containing an epoxy resin on its surface, the hygroscopicity of the surface on which a conductive circuit is formed is lowered and silver migration can be controlled. When the amount of the epoxy resin added is below 10wt%, the effect of preventing silver migration is small, and when its is above 50wt%, workability is lowered because mold release in releasing the laminate from the mirror plate after the laminate molding is worsened.
