Title: Device for preventing fixture of fixture driving machine from springing-out
Inventor: KAMIYA TOMOHIDE
IPC: B25C1/00
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To prevent fixtures with different lengths from springing-out by providing a closing member to be fixed to a rotating position when a gate is in the closing position while the closing member can turn when a gate is in the opening position.

IPC: B60W30/00
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To provide the system to control an automonous operation of a vehicle. SOLUTION: The manual operation of the vehicle is conducted by the system controlling the automonous operation of the vehicle in response to a speed and steering angle request signal from a navigator. The system includes a machine control module, an engine control module and a transmission control module. An automonous/manual selection signal informs the machine control module that the operation is completely in the automonous mode or in the manual mode. In the automonous mode, the navigator sends a speed request signal and a steering angle request signal to the vehicle. The machine control module receives the speed request signal and the steering angle request signal from the navigator. The machine control module receives the speed request signal and the steering angle request signal from the navigator through the reception above.

Title: Magnetic head
Inventor: SHIMIZU KOICHI
IPC: G11B5/127
Filed: 1985-10-09
Abstract: PURPOSE:To prevent the leakage of a magnetic flux, which arises on a magnetic head, by providing the 2nd coil preventing the leakage of the magnetic flux, which arises from the 1st coil at the time of recording. CONSTITUTION:The titled head is constructed with a slider 1 made of magnetic materials such as Mn-Zn and a core 2 made of ferromagnetic materials such as Mn-Zn, and the slider 1 is magnetically linked with the core 2. The 1st recording and reproducing coil 5 is wound on a window part 3, while on a window part 4 the 2nd magnetic flux leakage preventing coil 6 is wound. When a recording current is flowed in the recording coil 5, the magnetic flux 8 occurs in a magnetic circuit 7 and flows toward the parts 7a and 7b of the magnetic circuit 7. Since both the ends of the 2nd flux leakage preventing coil 6 are short-circuited, the magnetic flux with the reverse direction arises in the 2nd coil 6 the moment the flux 8 passes through the 2nd coil 6, and the flux 8 is suppressed to flow to the part 7a of the magnetic circuit. Thus the flux 8 passing through the position of the part 7b is substantially reduced, whereby the leakage of the flux from the top of the magnetic head can be prevented.

IPC: B60T8/1755
Filed: 1997-08-20
Abstract: PROBLEM TO BE SOLVED: To reduce the cost of a vehicle yawing control device by simplifying the structure of a fluid pressure brake circuit in the device. SOLUTION: If the running condition of a vehicle is estimated to have entered a drift-out state while the vehicle is turning to the right, the torques of the right and left front wheels 10, 12 and the right rear wheel 50 which is the turning inner wheel are controlled. The torques of the right and left front wheels 10, 12 are controlled by controlling electric motors 16, 18, while the torque of the right rear wheel 50 is controlled by controlling the fluid pressure of a wheel cylinder 53. Thus, since the fluid pressures of wheel cylinders 24, 22 need not be controlled in controlling the torques of the right and left front wheels 10, 12, the structure of a fluid pressure brake circuit can be simplified correspondingly, and the cost of a vehicle yawing control device can be reduced.

Filed: 1982-12-23
Abstract: PURPOSE:To obviate generation of noise even if the tape speed of a VTR on which an FM sound signal is recorded together with a video signal is made different from the speed in the stage of recording by detecting the envelope of a reproduced FM luminance signal, detecting the decrease in the level thereof and substituting the sound signal reproduced by the same with the signal after one vertical period. CONSTITUTION:Heads A, B trace the tape pattern like bold lines when run at two times faster than in the stage of recording in a tape pattern of an azimuth recording system shown in the figure. The level of an envelope detector 22 is discriminated with a discriminating circuit 23 and the pulse shown in the figure (c) is generated in a range of a prescribed level or below and further the pulse shown in the figure (d) is generated. These pulses are impressed on an FF24. On the other hand, a pulse is generated by a head selecting pulse as shown in the figure (e) by a waveform shaping circuit 25 and is used as a reset signal for the FF24. A change-over circuit 20 wherein the FF24 is reset at the starting point of a trace b1 is changed over to a voice detector 21 side of a track B, and is changed over to a voice detector 19 side of a track A by the next (f) pulse and thereafter the same operation is repeated. The signal at a terminal 26 is therefore the signal with which the signal shown in the figure (h) is detected and substantially no noise is generated.
