Title: Magnetic disk device
Inventor: YANAGIHARA SHUICHI
IPC: G11B21/02
Filed: 1990-11-26
Abstract: PURPOSE:To prevent head crush during crush stop by laying out a coil in a plane which passes through the center of gravity of an arm including a magnetic head and crosses a pivot axis. CONSTITUTION:Under actuator structure, a mount section of coil 10 is positioned substantially in the center of a middle arm 5 and arranged to be symmetric vertically. When the actuator drives, the force F which acts on the actuator is gravity G. Therefore, the reactions Ra and Rb which act on an upper bearing 3 and a lower bearing 4 are equalized. As a result, excessive force is not applied to one of the bearings so that no bearing may be damaged, thereby extending the service life of bearings. Since the force F acting on the actuator acts on the center of gravity G, no bending moment M is produced on a pivot shaft 1. This construction makes it possible to prevent the generation of head crush even when excessive force acts on the actuator during crush stop time.

Title: Thin film transistor
Inventor: YANAI KENICHI
IPC: G02F1/133
Filed: 1987-12-18
Abstract: PURPOSE:To make an OFF-current sufficiently small when a gate voltage is zero by a method wherein a liquid crystal cell driving thin film transistor in a gate coupled opposition matrix system is provided, where a threshold value of a drain current of the above transistor can be shifted toward a positive direction when the transistor is not selected. CONSTITUTION:A gate insulating film 20 is constructed in a five-layered structure that an electron trapping layer 5, barrier insulating films 4 and 6 formed of a SiO2 layer, and SiN layers 3 and 7 are laminated in layer. The layer 5 is composed of an a-Si:H layer large in a local level density and makes the threshold value of a drain current shift toward a positive direction and be controlled by the negative charge (electron amount) injected into the layer 5 from an active semiconductor layer 8. The films 4 and 6 enable the electric charge induced into the layer 5 to be stable, so that the charge is made not to change in amount when a gate voltage is applied in a normally operational state. Thereby, a threshold value of a drain current can be shifted toward a positive direction when a gate insulating film of a TFT is made to be of a multilayer structure, so that a drain current can be decreased to be sufficiently low when a gate voltage is zero.
