Title: Differential gear
Inventor: EDA TADASHI
IPC: F16H48/30
Filed: 1993-12-28
Abstract: PURPOSE:To prevent the rising delay of differential limiting torque and the generation of unnecessary differential limiting torque by providing a controller for releasing a pilot clutch by a fastening means only for the specified time upon detecting the turning of a body through a sensor. CONSTITUTION:A lateral G sensor 95 fitted to a body detects lateral G generated at the turning time or the like of a vehicle and sends a detection signal to a controller 89. The controller 89 recognizes the turning of the vehicle by this signal and cuts off the coil current of an electromagnet 87, a fastening means, for the specified time to release a pilot clutch at the time of starting to return a steering wheel to the right from the counterclockwise turning state or to the left from the clockwise turning state in slalom travel. The rising delay of differential limiting torque and the generation of unnecessary differential limiting torque can be thereby prevented, and the maneuvering stability of the body can be improved.

Title: Nonvolatile semiconductor memory device
Inventor: MIYAGAWA TADASHI
IPC: H01L29/788
Filed: 1989-12-27
Abstract: PURPOSE:To improve reliability by providing an erasing circuit, which supplys a high potential to an erasing gate at the time of erasing, and a source potential generating circuit, which sets a cell source potential to the prescribed potential. CONSTITUTION:An erasing signal ER is supplied to an erasing circuit EC and a source potential generating circuit VG, and the operations of the circuits are controlled. Further in a mode, a prescribed bias voltage is impressed to a source area 203 by the source potential generating circuit VG, and the potential difference between an erasing gate 207 and the source area 203 is decreased. Consequently in the erasing mode, an electric field impressed to the oxide film of the intersection part between the erasing gate 207 and the source area 203 is reduced. Thus the insulation of the oxide film is hardly destroyed, and a nonvolatile semiconductor memory device whose reliability is improved is obtained. In addition, since the electric field impressed on the oxide film at the intersection part between the erasing gate electrode 207 and the source area 203 is reduced, the thickness of the oxide film can be thin, and thus without forming the thick oxide film at the intersection part between the erasing gate electrode 207 and the source area 203, the dielectric breakdown strength at the intersection part can be improved.

Title: Method for preventing flow-out of slag at the time of discharging molten steel
Inventor: HIGUCHI YOSHIHIKO
IPC: C21C5/46
Filed: 1996-12-18
Abstract: PROBLEM TO BE SOLVED: To prevent the flow-out of slag together with molten steel discharged from a discharging hole of a vessel into a ladle and to improve the cleanliness of the steel by blowing high pressure gas with specific angle and specific gas flowing speed against the slag on the molten steel surface during discharging present just above the discharging hole of the vessel. SOLUTION: A converter 1 is tilted and the blown molten steel 2a is discharged into the ladle 13 from a steel tapping hole 8. At the time of tapping the molten steel, a blowing lance 10 is inserted from the opening hole of the converter 1 and the high pressure gas such as argon, nitrogen is blown to the slag 3 on the molten steel surface present just above the steel tapping hole 8 from a nozzle 10a at the tip part of the lance. This blowing lance 10 is e.g. incliningly loaded so as to be elevatable/lowerable through an elevating device 17 on a shifting truck 18 arranged on a working floor 21. The blowing of the high pressure gas is executed by setting the angle α of nozzle 10a to the slag surface to 20-90 deg. and the gas flowing speed to 100-1000m/sec.  By this method, the slag 3 is blown out without damaging the refractory in the furnace and without spouting the slag and the molten steel, etc., from the furnace, and the contamination of the molten steel 14 in the ladle is prevented.
