Filed: 1991-04-23
Abstract: PURPOSE:To form an electrode of hydrogen storage alloy very excellent in performance of cycle life, capacity value, etc., by adhesively sticking silver plating or a silver alloy to the hydrogen storage alloy. CONSTITUTION:Silver is plated, for instance, by a method of electroless plating to a hydrogen storage alloy crushed, for instance, under 100mesh. In this silver plating, the silver is plated by mixing silver liquid, consisting of silver nitrate, aqueous ammonia and sodium hydroxide, with reducing liquid, consisting of a methanol-base water solution mainly composed of glucose, by a predetermined proportion while stirred. Hydrogen storage alloy powder, thus obtained by applying silver plating, is fixed to a conductive supporter to form an electrode. As a fixing method, the powder is fixed by using an electrolyte resisting binder and press-attached to this supporter. In this way, electronic conductivity of a negative pole itself is improved to increase a cycle life and a capacity value by improving catalytic assistance at the time of storing/releasing hydrogen gas in a surface and reducing power of the hydrogen gas to water, and so on.

Title: Magnetic encoder
Inventor: UESUGI NORIHIKO
IPC: G01D5/245
Filed: 1988-05-19
Abstract: PURPOSE:To reduce the disorder of a detection waveform to a misalignment in the direction vertical to the moving direction of a sensor by shifting the magnetizing directions of adjacent magnetic zones by 90 degrees each other. CONSTITUTION:On a magnetic body 1, a magnetic zone 3a whose pitch and magnetization angle are l and 45 degrees, respectively, and a magnetic zone 3b whose pitch and magnetization angle are l' and -45 degrees, respectively are formed, respectively. In such a state, a relative moving distance in the (x) direction of the magnetic body 1 and a sensor 2 is detected by an anisotropic magneto-resistance element 4a of a magnetic detection use pattern pitch l/2 whose pitch is l and a magnetic detection use element 4b whose pitch is l'. In such a way, such a misalignment in the (y) direction of the magnetic body 1 and the sensor 2 as shown in a figure (b) is generated, and even when an overlap part 5 of the magnetic zone 3a and the element 4b is generated, since the element 4b has only sensitivity against a magnetic field in the x' direction, a magnetic field in the y' direction by the magnetic field 3a does not exert the influence on the element 4b. Accordingly, the title encoder can be strengthened against the misalignment in the direction vertical to the moving direction of the sensor by shifting the magnetizing directions of adjacent magnetic zones by 90 degrees each other.
