Title: Clutch control device
Inventor: KOSHIZAWA TOSHIBUMI
IPC: F16D48/02
Filed: 1986-06-23
Abstract: PURPOSE:To prevent shocks from being caused by causing the velocity of clutch release to be varied taking the current position of a clutch as a parameter, and then causing the velocity of clutch release within the range of a semi- engaged clutch where the disappearance of a transmission torque takes place at the time of the clutch release operation to be reduced. CONSTITUTION:When a vehicle is in operation, signals from a clutch- engagement-quantity detecting means 7 are inputted into an electronic controller 8 so that the current positions of clutch are read. Then, according to said clutch current positions, the velocity of clutch release by means of a clutch actuator 6 is obtained from an established characteristic curve. Said velocity of clutch release is set up in such a manner that, when the clutch is in a semi-engaged state, it is kept at a low speed, while, when the clutch is in the neighborhood of its fully-engaged position and its fully-disengaged position, it is increased to a speed higher than that in the semi-engaged clutch range. And further, it is judged whether the current position of clutch is in its fully-disengaged position or not, and when judged as 'NO', the actuator 6 is controlled its operation according to the then velocity of clutch release. While, when judged as 'YES', the actuator 6 is caused to stop its operation.

Title: Method and apparatus for detecting abnormality of twisted wire
Inventor: YAMAMURA TOMOO
IPC: G01B11/30
Filed: 1987-06-13
Abstract: PURPOSE:To detect the abnormality of an outer shape due to twist inferiority not appearing as the change in an outer diameter, by making the projecting axis of a flood light projector almost parallel to the twist angle of a twisted wire and receiving a projected image by a pair of photosensors to detect the difference between the quantities of the lights received by both photosensors. CONSTITUTION:The light projecting axis of a flood light projector 25 projecting the outer shape of a twisted wire 1 is made almost parallel to the twist angle of the twisted wire 1. The projected image is received by a pair of photoreceptors 26 and the output signals thereof are transmitted to a signal processing apparatus 30 through a differential amplifier 29. When the twisted wire 1 is normal, the projected images of both photosensors 26 are almost equal and the output thereof are slight and the output of the amplifier is also small. However, when the abnormal part 2 of the twisted wire 1 passes the photosensors, the outputs of both photosensors become unbalance and the output of the differential amplifier also becomes large to detect abnormality. Therefore, the abnormality of the outer shape of the twisted wire 1 due to twist inferiority not appearing as the change in the outer diameter thereof can be detected.
