Patent JP-H06245507-A (JP)
Title: Power supply circuit
Inventor: ANTONIUSU ADORIANUSU MARIA MAR
IPC: H02M3/28
Filed: 1993-12-27
Abstract: PURPOSE: To provide a power supply circuit that does not require expenses and requires only a small space on a printed circuit board. CONSTITUTION: A switch mode power supply circuit where a bipolar transistor T1 and a MOSFET T2 are used in series is publicly known and is called as a cascade circuit. In this circuit, a bipolar transistor is switched via an emitter instead of a base. Since the collector current of the bipolar transistor may greatly change, the base must be driven proportionally to prevent the bipolar transistor from deviating from a normal operation. Since a special coil winding Lb is provided in series with a cascade circuit at a transformer T, a proportional drive with less power consumption of the base of the bipolar transistor T1 is achieved. The special coil winding Lb is connected to the base via an inductance.

Inventor: SHINGU KUNIHIKO
IPC: B22D13/10
Filed: 1998-11-24
Abstract: PROBLEM TO BE SOLVED: To provide a difficult-to-wear and easy-to-repair fitting, and make molten metal difficult to enter. SOLUTION: When a cast-iron pipe is centrifugal-cast, this core fitting is installed on the core for the pouring cup of the cast-iron pipe P to support the core. The core fitting 20 is provided on its entire outer circumference with a ring 23 in close contact with the entire inner circumference of the core. If the ring 23 and core fitting 20 are formed concentrically and the core is fit in the core fitting 20, the core and the fitting 20 are made concentric and no clearance is produced. For this reason, there is not looseness, difficult to wear, and no entry of the molten metal. The ring 23 is shrink-fit and removable, and the binding force is increased, and the replacement is made easier by heating. This prolongs the service life and enhances productivity.

IPC: B60T8/1761
Filed: 1994-12-15
Abstract: PURPOSE: To improve braking in the turn of a vehicle by loosening braking to wheels and adding an additional value to a slip threshold value when the slip ratio of the wheels is larger than the slip threshold value. CONSTITUTION: In an antiskid controller 1, hydraulic pressure produced from a master cylinder 12 is applied through an ABS hydraulic unit 2 to wheel brakes of respective wheels 15-18 by brake pedal 11 stepped-on to brake the wheels. An electronic control section 3 detects the rotational speed of the wheel from a wheel speed sensor 51 to calculate the deceleration and slip ratio. When the wheel is braked and the deceleration of each wheel exceeds the threshold value of deceleration, the electronic control section 3 drives the ABS hydraulic unit 2 to perform antiskid control for the respective wheels 15-18. In the turning condition of the vehicle, the maximum frictional resistance exists in the wheel having the larger slip ratio, so that the slip threshold position is gradually increased to perform the optimum brake control.
