Patent JP-S63154954-A (JP)
Title: Air/fuel ratio sensor
Inventor: SEKIDO SATOSHI
IPC: G01N27/04
Filed: 1986-12-19
Abstract: PURPOSE:To enable control with a simple construction and a high S/N ratio, by arranging first and second electrodes on both sides of an electrolyte plate while a third electrode is provided to measure electric resistance of the second electrode. CONSTITUTION:First and second electrodes 2 and 3 are built up of a mixed conductor on both sides of a porous zirconia electrolyte 1 while a third electrode 4 is provided to detect electric resistance of the second electrode 3. Now in the case of excessive fuel, a rise in the electric resistance of the electrode 3 occurs when oxygen is lower than the equivalence point and is detected with the electrode 4 to reduce the fuel. In time, the oxygen will attain the equivalence point. At this point, a sharp drop occurs in the electric resistance and is detected with the electrode 4 to increase the supply of the fuel whereby the control of the air/fuel ratio is accomplished with a high S/N ratio to match energization current. In the case of excessive oxygen, the same operation is performed thereby enabling quick control with a simple construction.

Title: Sealing agent coating method
Inventor: SHINODA KENICHI
IPC: H01M6/08
Filed: 1988-12-02
Abstract: PURPOSE:To efficiently make an accurate coating job by injecting a pressurized sealing agent from a needle-shaped nozzle and by rotating a work at high speed in a specified cycle shorter than the opening time of a valve in the nozzle to apply the sealing agent to the surface of the work so as to draw a circle. CONSTITUTION:The hole diameter of a nozzle 5b is about 0.2mm. When a valve 5a is opened with a controller 6, a sealing agent pressurized with a pump 4 is injected as shown in (y) from the nozzle 5b. A dry battery 1 is positioned so that the sealing agent (f) is injected in a specified position on the inner surface of a zinc can 1a. When the sealing agent (y) is injected to the can 1a which is rotating at high speed (injection time is 0.1 second, and the rotating cycle of the can 1a is also 0.1 second.), the sealing agent is circularly applied to the inner surface of the can 1a as shown in (z). The sealing agent (z) makes just one revolution for 0.1 second on the inner surface of the can 1a so as to draw a circle. An accurate coating job is efficiently made.

That is, an additional boiling remaining time = an additional boiling time setting heater electrical energization calculation time. The heater electrical energization allowing part 7 performs an electrical energization as long as the additional boiling remaining time is not 0. Upon energization of electricity, the temperature control part 4 controls an electrical energization for the heater 2 on the basis of the hot water temperature detected by a temperature sensing part 3, so that the hot water in the hot water storing tank 1 is boiled up at the set temperature in an amount corresponding to its used volume.

Abstract: PURPOSE:To make it possible to easily carry out stable and highly adhesive plating on a Cu-W alloy by successively subjecting the alloy to specified heat treatment, thin Ni or Cu plating and heat treatment under specified conditions. CONSTITUTION:A Cu-W alloy 1 is heat treated by holding at 900-1,000 deg.C for >=10min in a furnace filled with a reducing atmosphere or in a vacuum furnace to remove scale, etc., on the surface of the alloy 1. The cleaned alloy 1 is quickly plated with Ni or Cr 3 in <=1mum thickness and heat treated by holding at 800-1,000 deg.C for >=10min in a furnace filled with a nonoxidizing atmosphere. By this heat treatment, a diffusion layer 4 is formed to firmly adhere the Ni or Cu plating 3 to the Cu-W alloy 1. Ordinary plating 5 is then formed on the pretreated alloy 1. Thus, stable plating can easily be carried out on the Cu-W alloy 1 having extremely inferior platability with high adhesive strength.
