Title: Positioning servo-control device
Inventor: ARAKI SHIGEYUKI
IPC: G05D3/12
Filed: 1977-10-31
Abstract: PURPOSE: To prevent the erroneous operations of a servomotor by selectively generating position signals, when a differential counter is at a zero level, and by prohibiting timing signals from being fed to the counter after that.  
     CONSTITUTION: The output of a differential counter 3 is converted into a speed indicating signal F by a D-A converting circuit 4. A timing signal generating circuit 1 takes into only the B signals of the positional signals A and B, which have their phases shifted at 90 degrees, so that timing signals D may be generated, when a movable body is moved a unit length, to count down the content of the counter 3. When the content of the counter 3 is reduced to zero, the positional signals A are fed through a switch circuit 6 to a motor drive circuit, and the timing signal generating circuit 1 simultaneously prohibits the timing signals D from being generated to the counter 3.

Title: Reproducing method

IPC: G11B15/467
Filed: 1990-05-21
Abstract: PURPOSE:To excellently detect a tracking error signal by setting a section where a crosstalk quantity can be detected long regardless of a tracking format. CONSTITUTION:A frequency signal (f1) detecting the crosstalk quantity is recorded every four tracks and only on one adjacent track of tracks where a signal for detecting timing (f2) or (f3) is recorded. Then, the crosstalk quantity in one direction is detected every time respective tracks are scanned by a second head. Besides, when two tracks are scanned by the second head 2, a tracking error is detected. That means, the detection of the crosstalk quantity by the second head is executed by the scanning of one track only in one direction. Therefore, the section where the crosstalk quantity can be detected is set long regardless of the track format. Thus, the crosstalk quantity is excellently detected.

Title: Tripod-shaped equal velocity joint
Inventor: MIZUKOSHI YASUMASA
IPC: F16D3/205
Filed: 1987-05-29
Abstract: PURPOSE:To enable a crew to reduce an uncomfortable feeling, by negating resultant axial force of resistance, relating to rolling of each spherical roller, by the resultant axial force, generated by a friction material, and eliminating vibration of a car body in its lateral direction. CONSTITUTION:When a tripod-shaped equal velocity joint receives torque to rotate, a contact part of a curved surface part 64 of a friction material 6, arranged in a symmetrical position to each spherical roller R, with a cylindrical part H1 of a housing H always generates friction resistance in the reverse direction for the resistance relating to rolling of each spherical roller R. Consequently, an axial force difference is transmitted to a shaft 7 as the residual axial force by the three spherical rollers R. Accordingly, vibration of a vehicle in its lateral direction relating to the axial force generates the natural vibration frequency of a vehicle body or the like to agree with the axial force generating frequency, and an uncomfortable feeling of the crew is eliminated because the vibration in the lateral direction is eliminated.

Filed: 1979-10-11
Abstract: PURPOSE:To prevent the generation of a noise due to mechanical vibration by connecting electrodes of two diaphragms so that voltages developed by sound pressure applied to diaphragms  will be added, and by composing an acoustic phase-shifting circuit of the acoustic resistance of a  sound absorbing material and the stiffness of a cavity. CONSTITUTION:Sound pressure in the direction of arrow A is applied to diaphragms 17 and 17'  via sound holes 15 and 15'. Diaphragms 17 and 17' vibrate in the center directions or external  directions simultaneously to develop voltages between electrodes of diaphragms 17 and 17' and  those voltage are summed up to obtain an output at the output terminal. On the other hand,  sound pressure in the direction of arrow B is led into the cavity via sound hole 21, sound absorbing material 22 and sound hole 20 and applied to inside suefaces of diaphragms 17 and 17'. This  sound pressure is also applied to outside surface of diaphragms 17 and 17' via sound holes 15 and  15'. The sound pressure led into the cavity is put out of phase by the acoustic phase-shifting circuit formed of the coustic resistance of sound absorbing material 22 and the stiffness of the cavity,  and consequently the sound pressure applied to both surfaces of diaphragms 17 and 17' becomes  equal to disallow diaphragms 17 and 17' to vibrate, thereby obtaining no output at the output  terminal.

Abstract: PURPOSE:To prevent the reverse current of the signal charge to a vertical charge transfer line for the horizontal transfer by providing a switch gate to the joint part between the vertical charge transfer line and a horizontal charge transfer line independently of a vertical transfer electrode. CONSTITUTION:The gate electrodes (switch gates) 17 and 18 are provided between the vertical charge transfer electrodes 11 and 13 and a horizontal charge transfer line 21 respectively.

Abstract: PURPOSE:To prevent an engine stall by judging whether the rotation of an engine is unstable or not with a controller and prohibiting an electric power steering device from operating if the engine rotation is unstable. CONSTITUTION:With the starter motor of an engine stopped and the engine 1 being rotated, an EGI controller 2 judges the complete combustion state of the engine based on the engine rotating speed signal N and the water temperature signal T of the engine cooling water and sends the operation positive/ negative signal P of a power steering device to a signal controller 6 depending on the judgment result.
