Title: Viscous fluid coupler device
Inventor: YAMAUCHI TSUNEKAZU
IPC: F16D35/02
Filed: 1998-10-29
Abstract: PROBLEM TO BE SOLVED: To prevent taken-in rotation of viscous fluid at the time of transferring from stopping of a cooling fan to rotation by making viscous fluid into first fluid and second fluid of higher specific gravity and lower viscosity than the first fluid, mixing both of the fluid at the time of rotor rotation and separating them after stopping. SOLUTION: When a drive shaft 11 is rotated from a state where viscous fluid is separated into first and second fluid 29, 30, a rotor 19 is integrally rotated, and as large quantity of fluid exists in a lower part in a working chamber 17, a housing 12 and a cover 14 are roughly integrally rotated by shearing force of fluid immediately after it, and the fluid 29, 30 is mixed and returns to a storage chamber 16 through a pump hole 18d. In this state, torque transmission to the housing 12 and the cover 14 by labyrinth grooves 20a, b is extremely small, and a cooling fan installed on the cover 14 is rotated at low speed. A communicating hole 18b opens at the time when bimetal 21 becomes higher than specified temperature, the fluid is supplied to the groove 20b, the fan is rotated at medium speed, and communicating holes 18a, b open and are rotated at high speed.  Consequently, it is possible to restrain unrequired taken-in rotation.

Title: Inversion preventing device
Inventor: HATANAKA KEIJI
IPC: H04N5/922
Filed: 1988-12-05
Abstract: PURPOSE:To reduce the circuit scale and cost of the device by selectively outputting inputted digital FM signals or the output of side-frequency wave suppressing filter in accordance with the output of a discriminator which discriminates whether or not the absolute value of the digital FM signals is lower than a prescribed value. CONSTITUTION:A discriminator 5 inputs quantized digital FM signals and discriminates whether or not their absolute value is lower than a prescribed value. A side-frequency wave suppressing filter 3 inputs the digital FM signals and suppresses upper and lower side-frequency waves or lower side-frequency waves. A selector 8 selectively outputs either the digital FM signals or the output of the filter 3 in accordance with the output of the discriminator 5. Therefore, the circuit scale and cost of this inversion preventing device can be reduced, since digital DM signals which are free from inversion can be obtained without using any divider.

Title: Working device rolling-operation structure of tractor
Inventor: FUKUMOTO TOSHIYA
IPC: A01B63/10
Filed: 1988-12-06
Abstract: PURPOSE:To improve the safety of the tractor by preventing the lateral swing of a working device when the working device is lifted in a state where a tractor is stopped. CONSTITUTION:An inclination sensor 9 detects the lateral inclination of the frame of a tractor on the horizontal surface and a computing means 10 computes the target length of a hydraulic cylinder 5 required for adjusting the position of the working device at a set angle on the horizontal surface on the basis of the detected inclination. Based on the computed result, a controlling means 12 allows the hydraulic cylinder 5 to elongate or shorten so as to give the target length. An angle sensor 11 further detects the swing angle of lift arms 3a and 3b. An adjusting means 12 adjusts the target length of the hydraulic cylinder based on the detected angle. A checking means 12 stops the operation of the adjusting means 12 while the angle sensor 11 detects the lifting state of the lift arms 3a and 3b. The working device 8 is consequently not swung laterally when the working device is subjected to a lifting operation in the stopping state of the tractor.

Filed: 1987-12-08
Abstract: PURPOSE:To enable rerecording simultaneously with erasing by laminating 1st-3rd layers successively from a light projecting surface side and specifying the Curie temps. and coercive forces of the respective magnetic layers. CONSTITUTION:This recording carrier is constituted, successively from the light projecting surface side, of a substrate 11, the 1st magnetic layer 12, the 2nd magnetic layer 13, and the 3rd magnetic layer 14. The coercive force of the 2nd magnetic layer 13 is smaller than the coercive forces of both the 1st magnetic layer 12 and the 3rd magnetic layer 14. The Curie point of the 2nd magnetic layer 13 is higher than the Curie point of the 1st magnetic layer 12. The carrier is so constituted that the magnetic field induced by the 2nd magnetic layer 13 is larger than the magnetic field induced by the 3rd magnetic layer 14 on the 1st magnetic layer 12 near the Curie temp. of the 1st magnetic layer 12. The desired recording is, therefore, executed regardless of the magnetization condition of the 1st layer. The recording is thereby executed simultaneously with erasing.

Title: Low frequency sound emphasis circuit
Inventor: KAKIHARA HISANOBU
IPC: H03G5/02
Filed: 1989-11-28
Abstract: PURPOSE:To reduce abnormal sound by providing a synchronization detection circuit detecting an amplitude of a component synchronously with a frequency of an output of a comparator of an output of a 1st low pass filter and applying an output of the synchronization detection circuit to a voltage controlled amplifier. CONSTITUTION:An input terminal is fed to a 1st LPF 1, from which only a required low frequency component is extracted. The signal is converted into a logic signal by a comparator 2 and frequency-divided by a T-FF3. Then the signal is given to a 2nd LPF 4, whose output is a sinusoidal wave. On the other hand, an output of the 1st LPF 1 is detected of its amplitude by a rectifier circuit 5 and a synchronization detection circuit 7 detects the amplitude of the component synchronously with the frequency of the output signal of the comparator 2, the output of the 2nd LPF 4 is controlled by a VCA 6 so that the amplitude is proportional to the synthesized value. Thus, the signal whose amplitude is proportional to a half of the frequency of the input signal is obtained and when it is fed to the original signal, the sound close to the original sound is obtained.
