Filed: 1983-02-04
Abstract: PURPOSE:To obtain an air cell having good strong-discharge and preservation characteristics by using a catalyst layer principally consisting of carbon powder and a manganese oxide which consists of both Mn5O8 and MnOOH. CONSTITUTION:MnOOH is thermally treated at 300 deg.C to obtain a manganese oxide consisting of both Mn5O8 and gammaMnOOH. Next 30pts.wt. of the thus obtained manganese oxide is combined with 20pts.wt. of active carbon, 20pts.wt. of carbon black and 30pts.wt. by the weight of the solid component of aqueous dispersion of polytetrafluoroethylene before the mixture is stirred and kneaded into a paste. The paste is then packed into a nickel screen of 40 mesh with a wire diameter of 0.1mm. to obtain a catalyst sheet of 0.4mm. thickness. The thus obtained sheet is thermaly treated at 300 deg.C to be given water-repellent property before being punched into a size of 11mm. diameter thereby obtaining a catalyst layer 1. Next a porous polytetrafluoroethylene film 2 is affixed to one surface of the catalyst layer 1 to make an air electrode 3. A button-type air cell is constituted by using the air electrode 3 as a positive electrode, zinc as a negative electrode and aqueous potassium hydroxide solution as electrolyte and by interposing a microporous resin separator 5 between the positive and the negative electrodes 3 and 4.

Title: Nickel-aluminum series super heat-resistant alloy ductile at room temperature
Inventor: IZUMI OSAMU
IPC: C22C19/03
Filed: 1979-02-16
Abstract: PURPOSE: To provide a super heat-resistant alloy having a good ductility at room temperature by adding a specific small amount of Zr or Nb to Ni-Al based alloy.  
     CONSTITUTION: To Ni 3 Al based intermetallic compound, a single or both of Zr and Nb is added in total amount of 0.01W3.0%. This addition of Zr and/or Nb nearly completely eliminates γ phase matrix whose strength at high temperature is extremely weak in Ni-Al alloy. This also eliminates brittleness inherent to Ni 3 Al having a good high temperature strength, resulting in an enhanced room temperature workability. Thus, the material is very suited to structure material that is subject to a high temperature for a long period of time, such as gas turbine blade, jet engine, and missile.

Title: Clamp circuit for video signal
Inventor: OKAMOTO NOBUYUKI
IPC: H04N5/16
Filed: 1991-01-18
Abstract: PURPOSE:To realize the clamp circuit at a low cost in which fluctuation of a pedestal level in a video signal is less. CONSTITUTION:A transistor(TR) Q3 amplifying a video signal is inserted between a clamp circuit C2 and a power supply Vcc supplying a charging current to the capacitor C2. Since the above TR Q3 is on the way of operation from an off-direction to an on-direction at a clamp point of the video signal, the impedance is equivalently low. Thus, a voltage drop due to a current charging the above capacitor C2 is less at the clamp point thereby suppressing fluctuation in the pedestal level.
