Filed: 1991-09-24
Abstract: PURPOSE:To decrease the insertion loss at a high frequency band by forming a piezoelectric layer with a laser abrasion method in a surface acoustic wave element formed by laminating a diamond and the piezoelectric layer. CONSTITUTION:A polycrystal diamond layer 2 is formed onto an Si substrate 1 with the microwave plasma CVD method by using H2 and CH4 as raw material gases, after the surface is polished to form 2 pairs of Al comb-type electrodes 3.

Title: Aluminum alloy spring retainer in valve gear mechanism of internal combustion engine
Inventor: HARA NOBUO
IPC: F01L3/10
Filed: 1999-08-30
Abstract: PROBLEM TO BE SOLVED: To eliminate the looseness of an inner shim and to reduce the mechanical noise generated from a valve gear system by preventing the abrasion of an engagement hole by fitting a guide ring made of hard metal and capable of inserting the inner shim, to the engagement hole formed on an upper surface of a central part of a retainer body. SOLUTION: A thin cylindrical guide ring 10 made of hard metal such as iron or the like is fitted in an engagement hole 5 of a spring retainer 2 in a state that it can not be rotated and vertically moved. An annular short inward flange 12 is connected to a lower edge of a cylindrical wall 11 of the guide ring 10, and contacted with a bottom of the engagement hole 5. On the other hand, an inner shim 7 is fitted in the guide ring 10 with proper clearance. Whereby the abrasion of the engagement hole 5 can be prevented even though the spring retainer 2 is made of aluminum alloy. Further the inward flange 12 is brought into contact with a lower surface of the inner shim 7 to prevent the guide ring 10 having a worn contact surface from upwardly slipping off from the engagement hole 5.

Title: Constant current circuit
Inventor: MIYAKE TOSHIHIDE
IPC: G05F3/22
Filed: 1988-09-27
Abstract: PURPOSE:To reduce the influence of the dispersion of a current amplification factor to an output current value by supplying a constant current based upon the difference of voltages generated between the base and emitter of two transistors(TRs) at the time of allowing an equal current into the collectors of two TRs respectively having different sizes of emitters. CONSTITUTION:3rd and 4th TRs Q3, Q4 for executing current mirror operation are provided. Current from a constant current source Q24 for feeding current to the 2nd TR Q2 is fed as the base current of the 2nd TR Q2 whose emitter is earthed through a resistor R1 and current is fed from a plus power source P as the base current of a 1st TR Q1 whose emitter is directly earthed. Thereby, the influence of a current amplification factor to the current flowing into the resistor R1 for setting up an output current value becomes the secondary influence of the inverse. Consequently, the influence of the dispersion of the current amplification factor to the output current value can be reduced.

Filed: 1986-10-15
Abstract: PURPOSE:To control a high frequency power source at a high speed thereby to reduce the loss of power consumption by providing a switching power source between a rectifying and smoothing circuit and a high frequency inverter. CONSTITUTION:A controller 122 of a switching power source 12 outputs a signal for turning ON or OFF a switching unit 121, and the ratio of an ON time to an OFF time is determined by an arbitrarily settable input command voltage (reference voltage). The unit 121 inputs a DC power, is controlled by an output signal from the controller 122 to output an intermittent pulse, rectified and smoothed by a rectifying and smoothing unit 123 to be output as a DC current. Here, when the frequency of the control signal is set to sufficiently high value as compared with the frequency for pulse-driving a whole laser generating high frequency power source 1, the power source 1 is pulse-driven without fail. Thus, the power source 1 can be controlled at a high speed, and the power loss in the unit 121 is reduced.
