Filed: 1984-09-06
Abstract: PURPOSE:To keep the tape driving speed at a fixed level by setting the length of a magnetic tape for check of music interval detector at such value that gives no effect to the revolving radius decided by the radius of a large-diameter hub and the thickness of a magnetic tape. CONSTITUTION:A cassette half 5 is set to a cassette tape recorder, and this tape recorder is set under a reproduction state. Thus a magnetic tape 8 for check of music interval detector wound round a hub 6 is taken up by a hub 7 at a fixed speed. Then the cassette tape recorder is set under a fast forward mode. Thus the tape driving speed is increased up to about 20 times as high as that of a reproduction mode although the shift of the tape 8 is equal to that of a reproduction mode. When the tape recorder is set under a rewind mode, the tape 8 is shifted to the hub 6 from the hub 7.

Title: Method for controlling differential control clutch for front/rear-wheel drive vehicle
Inventor: TAKAHASHI NOBUAKI
IPC: B60K17/35
Filed: 1988-07-27
Abstract: PURPOSE:To improve durability of a differential control clutch by performing active lubrication by way of opening, for a time, the clutch at every time when a specified shift control is carried out at a specified number, and changing the number according to the running condition of a vehicle. CONSTITUTION:An electronic controller 86 switches a clutch control valve 98 to a drain side at every time when a specified shift control in an automatic transmission is carried out at a specified time, in order to lubricate a differential control clutch 82 actively, whereby the clutch 82 is opened for a time. In this case, the specified number of the opening for a time is reduced as the average speed decreases since steer turning without driving increases as the vehicle speed decreases, so that the work amount (frictional energy) of the clutch 82 increases. It is thus possible to prevent reduction in the durability of differential control clutch.
