Title: Low-temperature sputtering unit
Inventor: MANABE KATSUHIDE
IPC: C23C14/36
Filed: 1978-11-15
Abstract: PURPOSE: To form a uniform metal film on a substrate product having vertical portion such as recesses or holes, by attaching a magnetic field-producing material to the substrate product cradle of a low-temp. sputtering unit, and by generating a magnetic field of a strength not lower than that desired strength at the desired position of the substrate product.  
     CONSTITUTION: A substrate product 12 having many holes 12a is placed on a substrate product cradle 8, and the vacuum tank 1 is evacuated, then Ar gas is introduced from a bombe 3 into the vacuum tank 1 in order to keep the tank at a suitable vacuum. A voltage is applied across the target 6 and an anode 7 so as to produce discharge. In the region where the electric field and the magnetic field generated by a magnet 10 cross each other, the electrons ionized by the discharge are in  magnetron and form plasma. The target metal sputtered by the Ar +  contained in the plasma advances nearly straight to the substrate product 12. Because a magnetic field is formed by a magnitic field generating material 11, the metal atoms diffract due to the effect of the magnetic field and form films on the hole sections 12a, which are hardly metallized essentially, to a thickness similar to that of the film formed on the other section.

Title: Cooling device mounted on vehicle
Inventor: FURUSE HIDEKAZU
IPC: F25D11/00
Filed: 1989-06-02
Abstract: PURPOSE:To prevent the occurrence of an overstroke and the generation of flash gas in a refrigerant piping by a method wherein a temperature detecting means is electrically connected to the control circuit of a drive device for a damper to prevent overcooling of a refrigerant in a condenser. CONSTITUTION:A control circuit 9 inputs an output signal from a thermistor 9a mounted in the vicinity of a condenser 12, and outputs a base voltage to a transistor 84. During normal operation, through running of a drive motor 83, a damper 8 holds an opening part 61 at a full opening state, and an air flow produced by a cooling fan 17 flows through a hollow cylinder body 6. Since, when the atmospheric temperature of the condenser 12 is decreased, a voltage applied on the transistor 84 is reduced by means of a signal from the thermistor 9a, the drive force of the drive motor 83 is reduced, and the damper 8 is operated in a closing direction by means of a restoring means. As a result, an amount of an air flow in the hollow cylinder body 6 is decreased to prevent a refrigerant in the condenser 12 from being overcooled, and the occurrence of the overstroke of a compressor 11 and/or the generation of flash gas in a refrigerant piping can be prevented.

Title: Sealed lead-acid battery
Inventor: OMAE TAKAO
IPC: H01M10/10
Filed: 1991-05-15
Abstract: PURPOSE:To manufacture a sealed lead-acid battery at a low cost by using a positive electrode lattice made of a lead-antimony alloy, filling and arranging the silica fine powder between a positive electrode plate and a negative electrode plate, and impregnating and holding a sulfuric acid electrolyte in the fine powder and the positive and negative electrode plates. CONSTITUTION:When a lead-antimony alloy is used for a positive electrode lattice, antimony makes a corrosion layer generated on the interface between the positive electrode lattice and an active material porous, and the binding among grains is made firm. The early reduction of the capacity and the dropping of the active material can be prevented, and the short circuit caused by the extension of the lattice can be reduced. The eutectic section of the positive electrode lattice is eliminated, thus the antimony elution quantity from the positive electrode lattice can be reduced, the silica fine powder arranged between the positive electrode plate and the negative electrode plate absorbs antimony, and the movement of antimony from the positive electrode to the negative electrode is blocked. The silica fine powder is an inexpensive industrial material and has an excellent holding capability of sulfuric acid, thus a sealed lead-acid battery can be manufactured at a low cost.
