Title: Rotary magnetic head device
Inventor: NEROME KUNITAKA
IPC: G11B5/52
Filed: 1988-09-28
Abstract: PURPOSE:To reduce the vibration of a rotary drum so as to make stable recording and reproduction by suppressing the displacement of the drum in the radial direction or uniformly displacing the drum in the radial direction even when centrifugal force is applied to the cylindrical section of the rotary drum rotating at a high speed at the time of recording or reproduction. CONSTITUTION:When recording or reproduction is performed by scanning a magnetic tape 11 by means of a magnetic head 7 rotating at a high speed by rotating a rotary drum 4 at a high speed together with a shaft 3 by means of a motor, centrifugal force is applied to the drum 4 and the upper side of the cylindrical section 4b deforms. However, since the supper side of the cylindrical section 4b is formed slightly smaller in diameter than the lower side of the section 4b, the diameter of the deformed upper side becomes almost equal to the diameter of the lower side. Since the cylindrical section 4b of the rotary drum 4 deforms as shown by the dotted lines at the time of rotation, vibration of the drum can be reduced and a good head touch and tape running can be realized with the magnetic head.

Title: Car brake control device
Inventor: INOUE HIDEAKI
IPC: B60T8/24
Filed: 1989-09-18
Abstract: PURPOSE:To enhance the cornering performance of a car by furnishing a brake liquid pressure control means to make adjustment so that the brake liquid pressure supplied to either of the left and right wheels becomes smaller than the brake liquid pressure supplied to the other wheel in compliance with increasing stamp force on a brake pedal when the car is put under control. CONSTITUTION:When a car is in cornering brakes, a changeover means 20 is operated to select one of the left and right wheels, and thereupon adjustment is made by control means 13, 14 so that the brake liquid pressure supplied to the outer wheel viewed in the turning direction will become smaller than the brake liquid pressure supplied to the inner wheel. Accordingly a yaw-rate peculiar to the car body is generated on the basis of the synergism of a yaw- moment, which originates from unbalance of brake liquid pressures supplied supplied to the left and right wheels under covering, and a sideways force resulting from operation of the steering wheel. The understeer tendency of the car is offset with this yaw-rate. The steering characteristic of car is transferred temporarily to the oversteer tendency.
