Title: Revolution speed detection method by generator
Inventor: ONO HIDETAKA
IPC: G01P3/481
Filed: 1978-10-27
Abstract: PURPOSE: To realize the high-stability speed governing by converting the output of the generator coupled directly to the engine main shaft into the pulse signal proportional to the revolution speed via the frequency converter comprising the multi- phase full wave rectifying part and the high pass filter.  
     CONSTITUTION: For example, 3-phase and 14-pole AC generator 2 is coupled directly to the main shaft of diesel engine 1 to generate the 3-phase AC power. The output of generator 2 is supplied to frequency converter 5 to undergo the 3-phase full wave rectification. Thus the DC component of the ripple waveform is eliminated, and the AC waveform proportional to the revolution speed is delivered. Frequency- voltage converter 4 supplies the AC voltage to generate the DC voltage proportional to the input frequency which is then delivered to electric governor 3. Governor 3 compares the DC voltage with the reference set voltage, and an arithmetic process is given to the difference to give the control to obtain the revolution speed of engine 1 equal to the set value.

Title: Production of thin alloy film

IPC: G11B5/851
Filed: 1982-08-02
Abstract: PURPOSE:To apply always a specified amt. of a non-essential component on a thin film at a high filming speed in a method for forming a thin alloy film on a substrate in a vacuum by directing the vapor flow of one material and the sputtering particles of the other material simultaneously toward the substrate. CONSTITUTION:Co which is an essential component is evaporated by heating on a substrate of a synthetic resin film; at the same time, a slight amt. of Cr which is a non-essential component to be incorporated is sputtered, in the production of, for example, a vertical magnetization recording medium of a non-coated type. The resulted vapor flow of Co and the sputtering particles of Cr are directed simultaneously toward the substrate film. Since the essential component is vapor-deposited by ion plating, the filming speed is high. Since the non-essential component is filmed by sputtering, always a specified amt. can be added into the thin film and the filming speed over the entire part is not affected by the low speed with the sputtering as the non-essential component is very slight in content.
