Title: Hydrogen storage alloy electrode
Inventor: KATO HITOSHI
IPC: H01M4/24
Filed: 1997-10-08
Abstract: PROBLEM TO BE SOLVED: To provide a negative electrode which satisfies a demand for rapid high efficiency charge/discharge and by which battery performance and the service life can be improved by arranging a nickel coating film between a conductive coating film and a hydrogen storage allay particle surface. SOLUTION: This electrode is coated with conductive metal after backing nickel covering is performed on at least a hydrogen storage allay particle surface. Silver, copper, gold and cobalt having electric conductivity higher than nickel are desirable as the conductive metal. It is desirable to perform the backing nickel covering by forming the hydrogen storage alloy powder surface in a recess-projection shape so as to exhibit an anchor effect further by soaking hydrogen storage alloy powder in, for example, an alkaline aqueous solution not less than 60 deg.C. Powder having the particle size of 1 to 200 μm such as MmNi5 (Mm is misch metal), TiNi, ZrNi2 and ZrV2 , is desirably used as hydrogen storage allay. Evaporation, ion plating and aqueous solution utilizing plating are performed on the nickel covering.  Therefore, a storage battery which hardly dissolves in an alkaline solution and is excellent in the cycle service life and internal pressure resistance, can be obtained.

Title: Pulse laser device
Inventor: ROBAATO JIEI ROODEN
IPC: H01S3/097
Filed: 1990-10-26
Abstract: PURPOSE: To generate a pulsating laser output beam where the amplitude, shape and duration of the pulse satisfy preselected parameters by providing means for modulating power being supplied to a laser. CONSTITUTION: An output beam 3 is emitted when power is fed to an apparatus comprising a ceramic/tungsten argon laser tube 2. When a controller 6 is positioned in the passage of the beam 3, a filter 41 passes the longer (green) waveform and blocks the majority of shorter (blue) waveform. A DC laser power supply 4 supplies the laser tube 2 with a high voltage power in response to an electric control signal from the controller 6. In response to each control signal, the power supply 4 supplies the tube 2 with a power for a time sufficient to emit a pulse having a desired duration from the tube 2. The tube 2 is driven into ionized state in response to a control pulse being fed to an MOSFET passing bank in the power supply 4. No tube current flows during the duration of that pulse and generation of heat is suppressed.
