Title: Button-type air zinc battery
Inventor: YOKOYAMA TAKAO
IPC: H01M12/06
Filed: 1983-06-16
Abstract: PURPOSE:To obtain a button-type air zinc battery of high reliability by improving its capacity, liquid leakage resistance and preservation characteristic by using oxygen as a positive active material, amalgamated zinc as a negative active material and caustic alkali solution as electrolyte. CONSTITUTION:An air intake hole 2 is provided in a positive case 1. A cellulose- system porous paper 3 installed in an air chamber diffuses air and absorbs electrolyte discharged from an air electrode 5. The air electrode 5 is prepared by applying a catalyst composed of manganese dioxide, active carbon and a conductive member to a current collector consisting of a porous nickel body. In a sealing plate 9 coupled with a gasket 8 made of nylon, amalgamated zinc powder and caustic alkali electrolyte are packed. Here, the amount of the electrolyte per 1mAh of zinc is adjusted of 0.24-0.28mul. If it is smaller than 0.24mul, the utilization rate of zinc is low and battery capacity decreases. In contrast, if it is larger than 0.78mul, although the utilization rate of a negative electrode 10 improves, liquid leakage occurs during storage or in the last stage of electric discharge. In order to prevent such a phenomenon, it is preferred that the packing rate in the sealing plate 9 and the concentration of the electrolyte be adjusted to 75-85% and 28-32% respectively.

Title: Slant pole of magnetic recording and reproducing device
Inventor: IKEDA YOSHIAKI
IPC: G11B15/60
Filed: 1984-05-31
Abstract: PURPOSE:To hold the normal run of a magnetic tape so as to reduce the frictional force, by constituting a rotary section which is smaller than the width of the magnetic tape and a fixed section which controls the movement of the tape so that the tape cannot be moved in undesired directions by the rotary section at the section where the magnetic tape is wound. CONSTITUTION:A slant pole 4 is equipped with a rotary section 4a having a width S smaller than the width A of a magnetic tape 1. The rotation of the rotary section 4a is made around the axis of the slant pole 4 and its rotating direction is not normal to the running direction of the magnetic tape 1. This is because the slant plate 4 is standed under an inclined condition. Therefore, when force being applied to a minor area of the magnetic tape 1 is considered, the force in the running direction of the magnetic tape 1 and the force in the rotating direction of the rotary section 4a are applied to the area and the upward force of the slant pole 4 acts on the magnetic tape 1. Therefore, the width B of the rotary section 4a is made smaller than that A of the magnetic tape 1 to prevent the upward movement of the magnetic tape 1.

Abstract: PROBLEM TO BE SOLVED: To enable draining materials to rapidly and smoothly drain water to the outside of an embankment by holding a bandle of strands aligned with each other with a binding material so as not to disentangle and so as to make the external face water-permeable when embedding the bundle in the ground. SOLUTION: A bundle 14 is held by a binding member 16 so as not to disentangle and to make the external face water-permeable when embedding the bundle in the ground, to form a draining material 12. The draining materials are longitudinally and laterally arranged at every specified height to form a shape such as meshes of a net in turn, and an embankment is formed in sequence. The longitudinal draining materials 12B are put on the lateral draining materials 12A and at least tooth lateral ends are protruded from the slope face 12a of the embankment 22 to form drain outlets 13.  Rainwater collected in the longitudinal draining materials 12B transfers to the lateral draining materials 12A through the intersections with the lateral draining materials 12A and is discharged to the outside of the embankment 22 through the drain outlets of the draining materials 12A, even if the longitudinal draining materials have not drain outlets. Accordingly, rainwater collected in the draining materials can be rapidly and smoothly drained to the outside of the embankment.
