Title: Valve operating mechanism of diesel engine
Inventor: GOJIMA YUTAKA
IPC: F01L1/04
Filed: 1979-08-01
Abstract: PURPOSE: To change automatically opening/closing timing of intake exhaust valves by providing the valve operating mechanism with two cam shafts to open and close the valve, in which the relative engles to the cam shaft driving gears shall be variable.  
     CONSTITUTION: A valve opening cam shaft 3 and a valve closing cam shaft 4 are driven by cam shaft driving gears 1, 2, respectively, and their relative angles to the gears 1, 2 are variable. Torque on the cam shafts 3, 4 is transmitted to an oscillating lever 7 through rollers 9, 10, and further to a tappet 11 and a push rod 12 to open and close the intake exhaust valves of a diesel engine. Change of the relative angles of cam shafts 3, 4 to the gears 1, 2, respectively, shifts the opening/ closing timing of the intake exhaust valves automatically, which can contribute to eliminating unfavorable color of the exhausted gas due to blowback of the exhausted gas to the gas supply system at the time of low-load operation or due to drop of the compression temperature and piston temperature.

Title: Television camera
Inventor: MIYAWAKI SEIGO
IPC: H04N5/335
Filed: 1989-04-19
Abstract: PURPOSE:To send a video signal of plural camera head sections through one transmission line only by switching a video signal of the two camera head sections in one camera head for each horizontal scanning period and sending the result. CONSTITUTION:A switching circuit 8 switches an output signal of a video signal processing circuit 6 and a video signal processing circuit 12 for each horizontal scanning period with a synchronizing signal from a synchronizing signal generating circuit 7, and a detection signal addition circuit 9 adds a vertical synchronizing signal and a detection signal identifying the video signal of camera heads 1, 2 outputted from the synchronizing signal generating circuit 7 to the video signal and sends the result to a transmission line 3. A composite video signal is inputted to a detection signal separation circuit 13, a 1H delay circuit 14, and switching circuits 15, 16 in a controller 4. The switching circuits 15, 16 use the detection signal and the vertical synchronizing signal to reproduce the video signal of the camera heads 1, 2 from the composite video signal and its 1H delay signal. Thus, number of the transmission lines is halved in comparison with that of a conventional camera thereby suppressing increase in cost.

Title: Differential amplifier circuit
Inventor: NAITO HIDETOSHI
IPC: H03F3/45
Filed: 1997-04-16
Abstract: PROBLEM TO BE SOLVED: To exactly match the frequency characteristics of a pair of complementary signals by inserting inductors to the respective drain loads of a pair of FETs at a differential transistor part for comparing an input signal with a reference voltage at a differential amplifier circuit having the differential transistor part and a source follower part for outputting a pair of complementary signals corresponding to the compared result. SOLUTION: Inductors 15 and 16 are inserted to the drain loads of a pair of FET 4 and 5 consisting of a differential transistor part 3a and the values of inductors 15 and 16 are adjusted so that the frequency characteristics of a pair of complementary signals Q and XQ outputted from a source follower part 6 can be matched. Namely, by setting the value of inductor 16 on the side of A larger than the value of inductor 15 on the side of XQ, the frequency characteristics of Q are shifted to the side of high frequency without shifting the frequency characteristics of XQ to the side of low frequency and both the characteristics are matched. Thus, the amplitude of Q can be matched with that of XQ.

IPC: G11B7/09
Filed: 1987-04-24
Abstract: PURPOSE:To support a moving part without inclination by supporting the moving part including an objective lens movably and displacably to a fixed part with a wire to form a bent part arranged in a point symmetry to the gravity center of the moving part. CONSTITUTION:A moving part 20 is supported by a wire 10, and both side surfaces at the remotest position from the gravity center of the moving part 20 are supported at the section of the fixed part so that the rigidity can be made largest to the rotation of the moving part 20.

For the wire 10, the rigidity is comparatively small in a Z shaft direction and an X shaft direction and it is comparatively large in a Y shaft direction, and therefore, the moving part 20 can be displaced with the Z shaft direction and the X shaft direction as the focusing direction and the tracking direction. A supporting member is of an S-shape, arranged so as to come to be a point symmetry to the gravity center of the moving part 20, and the wire 10 is linked by an attenuating material 11 between adjoining lines in the part bent to 180 deg..
