Title: Fitting gas phase plating method
Inventor: OKAMOTO SHIGETAKA
IPC: C23C14/24
Filed: 1979-03-22
Abstract: PURPOSE: To evenly hold the clearance between both members and applying concentrical plating layers by giving the degrees of freedom being two-dimensional in the diametral direction to one of fitted bodies and relatively rotating the both members to align their centers.  
     CONSTITUTION: When rotation is given to a plunger 2, it moves always in the direction where the friction force between the fitting surfaces becomes minimum because the plunger 2 has the degrees of freedom being two-dimensional within the XY plane, whereby the center run-out and offcenter are automatically corrected. Further the forceful offcenter correction action along with the progression of plating is added and this self-centering action obviates the continual contacting of the fitting surfaces of the barrel 1 and plunger 2 or the specific portions of the plating layers 1a, 2a surfaces with themselves and causes these to make even contact with plating vapor, whereby the plating layers 1a, 2a of concentrical form and even thickness are formed and eventually the center 0 of the barrel 1 and the center 0' of the plunger 2 align.

IPC: G06F3/02
Filed: 1997-02-18
Abstract: PROBLEM TO BE SOLVED: To attain improvement in operability by setting whether a function instructing means can be used or not based on how many times respective functions are instructed. SOLUTION: The read position of command memory is defined as leading command information (S70). A value stored in the count part of command information is compared with a threshold value stored in a threshold value part (S73) and when the value stored in the count part is larger than the threshold value, a display flag is raised (S74). When the value stored in the count part is equal to the threshold value stored in the threshold value storage part or the value stored in the count part is smaller, the display flag is dropped (S75). Next, the read position of command memory is defined as the next command information (S76). The presence/absence of command information is discriminated (S77) and when there is command information, processing after S73 is repeated but when there is no command information, processing is finished.

Filed: 1981-03-10
Abstract: PURPOSE:To measure the surface temperature of a material from the electromotive force between two parts accurately, by forming at least the surface of the material whose surface temperature is to be measured by a raw material having excellent thermal electromotive force characteristics, and contacting a probe, which comprises a raw material that forms a thermcouple with the material to be measured, to said surface of the material to be measured. CONSTITUTION:The pipe of a heat exchanger of a boiler is made of carbon steel or low alloy steel, and a copper pipe is used as a model or the copper is evaporated. The copper wire is used as a lead wire and taken out of the pipe surface. Meanwhile, a thin, rod shaped probe made of Constantan is guided to the outside of the boiler and connected with the copper lead wire. When the Constantan probe is pushed to the copper part of the pipe surface, the thermocople is formed between the copper and the Constantan. Since the electromotive force is generated by the temperature difference between the pipe surface and the room temperature outside the boiler, the temperature of the pipe surface is measured by measuring said electromotive force.
