Title: Anti-water slide member for internal combustion engine
Inventor: SHINADA MANABU
IPC: F16J10/04
Filed: 1990-11-30
Abstract: PURPOSE:To obtain an anti-wear slide member for an internal combustion engine which is improved in an anti-wear quality, by forming electroless nickel or cobalt-tungsten-boron or phosphoric alloy plating at a place where opposing members are relatively butted or slide-contacted. CONSTITUTION:The deposit of the alloy plating of electroless nickel-tungsten- boron, cobalt-tungsten-phosphorus or cobalt-tungsten-boron is conducted at a portion which is shown by thick lines and extends over the whole length (b) of the inner surface of a cylinder liner 1 and its top ring sliding range (a). Hardness under the deposited condition is at more than 800 micro Vickers even without heat treatment, and the film of this hardness is formed. Also, when heat treatment is conducted for an hour at 400 degrees Celsius, the hardness becomes at micro Vickers 900-1200, and the quality of anti-wear is further increased. And as electroless plating is good in uniform electrodeposition, thickness becomes uniform, and the film is formed uniformly even at a complex shape or a peak position.

Filed: 1998-11-24
Abstract: PROBLEM TO BE SOLVED: To prevent development to burnt damage of a voltage measuring line caused by accidental short-circuiting of the voltage measuring line by installing a voltage measuring terminal through a resistor. SOLUTION: A voltage measuring terminal 50 is installed separately from a terminal board 20 to which electric power is supplied, and a resistor 60 is connected between the voltage measuring terminal 50 and the terminal board 20. By this circuit constitution, even if a short circuit is produced between voltage measuring lines 41, 42, current flowing in the voltage measuring lines 41, 42 is limited by the resistor 60, and development to an accident such as burnt damage of the voltage measuring lines 41, 42 is completely prevented. In addition, since a voltage measuring device 40 is not a circuit consuming current, current flowing through the voltage measuring lines 41, 42 during measurement is very small.  Accordingly, even if the resistor 60 is inserted in series between the voltage measuring lines 41, 42, large error does not produce in a voltage value measured with the voltage measuring device 40. A voltage supply system with high safety is constituted.
