Title: Four-wheel-drive type working vehicle
Inventor: TAKAHASHI SEIICHI
IPC: B60K23/08
Filed: 1987-02-09
Abstract: PURPOSE:To reduce impact in turning by cutting the power transmission to front wheels only during a set time when a steering wheel for steering the front wheels is operated by a set steering angle or more and operating a front wheel speed change gear to the acceleration side after the set time. CONSTITUTION:A knuckle arm 21 of front wheels 1 steered by a steering wheel 20 is provided with a steering angle detecting sensor 22 for sending the detecting signal to the input of a controller 23. And while the steering angle of front wheels 1 is between a straight travelling position theta0 and a set steering angle theta1, a controlling valve 24 for respective first and second hydraulic clutches 18, 19 of a front wheel speed change gear 10 is operated to the pressurized oil supply side for the first hydraulic clutch 18 to be maintained under the reference drive condition 4WD-I. On the other hand, when the steering angle of front wheels 1 exceeds the set steering angle theta1 in quick turning, the operational signal for the controlling valve 24 is interrupted only during the set time. Thus, the respective hydraulic clutches 18, 19 are turned off and only rear wheels 2 are maintained under the two-wheel drive condition.

Title: Velocity controller for magnetic tape
Inventor: IKEDA HIROSHI
IPC: G11B15/54
Filed: 1989-02-08
Abstract: PURPOSE:To reduce fluctuation in the tape speed by providing a first and a second error amplifiers, and a torque commandor to add the output voltages of the first and second error amplifiers and to control the current of a motor which drives a magnetic tape. CONSTITUTION:Any frequency component of speed fluctuation generated on the magnetic tape is amplified as voltage fluctuation uniformly by the error amplifier 17, and converted to the driving torque of a reel motor 6S(6T) in a direction to cancel the speed fluctuation by the torque commandor 7S(7T). However, constant tape speed fluctuation remains due to resonance by the elasticity of the magnetic tape and the inertia of a tape feed system only by using the error amplifier 17. Then, a guide roller component in a tape speed fluctuation component can be reduced by adding the output voltage of the error amplifier 18 on the output of the error amplifier 17. In such a manner it is possible to reduce the guide roller component in a tape cassette in which the tape is feeding and to reduce the speed fluctuation of the magnetic tape.
