Title: Battery jar of storage battery
Inventor: TOUFUN KIMIYOSHI
IPC: H01M2/02
Filed: 1979-02-17
Abstract: PURPOSE: To prevent reduction of electromotive force when environmental temperature drops, by arranging hollow portions in the wall of the storage battery jar body, thereof to provided heat insulating characteristics.  
     CONSTITUTION: In the wall material (1) of a storage battery jar, hollow portions (2) are formed which are separated and independent from each other and isolated from the interior or the exterior of the jar. Accordingly, when the temperature outside the storage battery drops, the interior of the battery is prevented from cooling down due to the adiabatic effect of the hollow portions (2) and the reduction of electromotive force can thus be prevented effectively.

Title: Electron beam vacuum evaporation
Inventor: MIZUKAMI ETSUO
IPC: H01L21/363
Filed: 1984-01-31
Abstract: PURPOSE:To maintain stable vacuum evaporation procedures by preventing charge up at the surface of sample pellets by winding a high melting point metal mesh to the sample pellets. CONSTITUTION:A belt type mesh 5 is wound around a sample pellet 1 in such a case as using a high insulation semiconductor material as the sample pellet 1 for the vacuum evaporation source. As the mesh 5, a high melting point metal material such as W, Mo, etc. is used. The sample pellet 1 wound by the mesh 5 is placed on a sample holder 2 and an acceleration voltage is applied across the sample holder 2 and a gun 3 from an acceleration voltage source 4. Thereby, the electron beam generated by the gun 3 collides with the surface of sample pellet 1 and the vacuum evaporation is carried out. Since the mesh 5 having a high conductivity is wound at the surface of sample pellet 1, the electron having collided with the sample pellet 1 is not accumulated at the surface of sample pellet 1 and is transferred to the sample holder 2 through the mesh 5. Accordingly, charge-up of sample pellet 1 is cancelled and stable vacuum evaporation procedures are maintained.

IPC: G11B21/02
Filed: 1985-01-30
Abstract: PURPOSE:To prevent runaway of pickup means beyond the extent of the recording medium by controlling the rotation of a driving motor by the operation of a detection switch. CONSTITUTION:Detection switches SW1, SW2 arranged on both end sides of guide rails 6, 7 are mechanical switches.

Title: Method for detecting ruggedness of magnetic metal plate
Inventor: WASA YASUHIRO
IPC: G01B11/30
Filed: 1990-01-26
Abstract: PURPOSE:To rapidly and easily detect the ruggedness of a metal plate from the rotational angle of a polarization face of reflected light reflected from a substance having a pole Kerr effect by making a spot-like straight polarized light incident upon the substance so as to sweep its surface. CONSTITUTION:A magnetic field is impressed in the direction parallel with the surface of the magnetic metal plate 1 by using a permanent magnet 2 and a york 3 having high magnetic permeability in order to detect a recessed part 10 on the surface of the plate 1. In the vicinity of the recessed part 10, a leaked magnetic field 11 is distributed on the surface and an iron thin film 6 is formed on a non-magnetic base 5 in the vicinity of the magnetic field 11. The thin film 6 is magnetized by the magnetic field 11 and allowed to have the pole Kerr effect. Then, straight polarized light 8 is made incident from a polarizing light source 7 to the thin film 6 and the rotational angle of the polarized face of the reflected light is detected by a photodetector 9. Consequently, the size of the leaked magnetic field, i.e. the existence and size of a rugged part, can be known. Since the incident straight polarized light is like a spot, the magnetic field can be locally measured and the wide distribution of the leaked magnetic field can be known by sweeping the spot on the thin film 6.
