Patent JP-S62261739-A (JP)
Title: Power transmitting device
Inventor: KITANO KOJI
IPC: F16D43/284
Filed: 1986-05-06
Abstract: PURPOSE:To make automatic on-off switching of torque possible and improve responsiveness by combining an oil pump driven by relative rotation between input and output shafts and a slip type clutch which makes engagement between the input and output shafts by means of discharge pressures of the pump. CONSTITUTION:When slip occurs at a rear wheel, a difference in rpm is produced between an input shaft 13 and a 2nd output shaft 18, and an oil pump 60 is driven by this relative rpm. And since the discharge oil pressure of the pump 60 increases with the relative rpm, the oil pressure in an oil pressure chamber 45 becomes higher, and clutch plates 41 and 42 increase engagement force while they are slipping to distribute torque of an input shaft 13 to the 2nd output shaft 18. As a result, the rpm of the output shaft 18 increases and approaches the rpm of an output shaft 15 to reduce or eliminate the slip at the rear wheel. Since the relative rpm between the output shafts 15 and 18 becomes smaller as the slip is reduced, the discharge pressure of the oil pump 60 is also reduced and transmitted torque is also reduced. Accordingly, tight corner braking is prevented when the relative rpm is small and, at high speeds, fuel economy is improved.

Filed: 1990-04-19
Abstract: PURPOSE:To simplify the structure of an apparatus by rotation-driving a rotor through a driving rod generating a torsional oscillation. CONSTITUTION:When respectively predetermined voltages are applied to respective electrodes 4A, 4B, 5A, 5B of a driving rod 3, one side piezoelectric material 3A stretches in the spiral direction and the other side piezoelectric material 3B shrinks in the spiral direction so that torsion is generated in the direction of the arrow A as a whole, and when the application of voltage is stopped, the driving rod returns to the original condition by its reaction force. When the voltage applied to respective electrodes 4A, 4B, 5A, 5B is gradually raised, the driving rod 3 is twisted gradually and when the application of voltage to respective electrodes 4A, 4B, 5A, 5B is stopped, the driving rod 3 abruptly turns in the direction opposite to that at the time of application of voltage (direction of recovering from torsion) by its reaction force. Thus, a rotor 10 revolves when the application and stop of voltage are repeated at a high-frequency period.

Abstract: PURPOSE:To adopt small circuit constitution for a switching circuit, to reduce the size of a semiconductor chip and to supply chips inexpensively by constitut ing a switching element of an N-channel or a P-channel transistor(TR). CONSTITUTION:When a control terminal 12 is at a VDD level (high level) and an input terminal 11 is at a VSS level (low level), an N-channel TR 14 is turned off and an output 15 reaches the VSS. Thus, an inverter comprising a P-channel TR 16 and an N-channel TR 17 outputs the VDD to an output terminal 13 because the inverter receives a VSS input. That is, a signal at the terminal 11 is sent to the terminal 13. when the VDD is supplied to the terminal 12 and the VDD is fed to the terminal 11, and when the output 15 is at a constant voltage, the TR 14 is turned on and a voltage difference between the terminal 12 and the output 15 is equal to the absolute value of the threshold voltage of the N-channel TR and the output 15 does not exceed the equivalent level, then the TR 16 is turned off and the VSS is outputted from the terminal 13. Thus, the size of the semiconductor chip is decreased and the cost is reduced.

Abstract: PURPOSE:To permit angle modulation signals corresponding to '1' and '0' exist in one bit in a specific state when a collision occurs by permitting a byphase signal corresponding to transmission data to amplitude-modulate the angle modulation signals. CONSTITUTION:A frequency switching circuit 8 switches the outputs of oscillation circuits 6 and 7 in accordance with data shown in a graphic (a), and outputs signals shown in a graphic (b). An encoding circuit 9 converts data in the graphic (a) into the byphase signals and accordingly switch-controls a switch 10 and generates a transmission signal shown in a graphic (d) from the output of the frequency switching circuit 8. The high frequency signal of fH is transmitted in the first half of one bit-period and it becomes silence in the latter half in the state of '1'. On the other hand, it becomes silent in the front half of the one bit-period and the high frequency signal of fL is transmitted in the latter half in the state of '0'. When data collide, the signal of fH exists in the front half, and the signal of fL exists in the latter half. Thus, the collision can be detected if the signal state is detected.
