Title: Control device of dc brushless motor
Inventor: ISOBE TOMONORI
IPC: H02P6/15
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To prevent reverse current after communication, reduce fluctuation of torque in communication, and improve operation efficiency by performing there-phase conduction for communication, switching to bi-phase conduction, and switching a switching element from a continuous ON to intermittent ON, or from intermittent ON to continuous ON. SOLUTION: For example, three-phase conduction of U-phase continuous ON, V-phase PWM, and W-phase continuous ON is made between A0 and C0, while a bi-phase conduction of U-phase PWM, V-phase continuous ON, and W-phase OFF is made between B0 and C0. In this manner, by setting to the three-phase conduction within a specific electrical angle when switching from the specific bi-phase conduction to another bi-phase conduction, the torque fluctuation to a rotor can be reduced and operation efficiency can be improved. Also, after communication, conduction to coil winding of a phase at a downstream side for the rotary direction of a rotor can be made continuous conduction from PWM control, while conduction to the coil winding of a phase at a upstream side is set to PWM control.

Title: Suction air throttle controller of diesel engine
Inventor: ITOU TOSHIHIKO
IPC: B60W10/18
Filed: 1981-08-05
Abstract: PURPOSE:To eliminate the application of a vacuum pump by introducing a pressure at the lower side of a suction air throttle valve into a brake booster. CONSTITUTION:Both flow lines extending from a negative pressure take-out port 9 which opens to a suction pipe 1 at the lower side from a suction air throttle valve 2 and from a vacuum pump 10 via check valves 11 and 12, respectively, meet before running into a brake booster 13. When an engine is turned ON, a computer 5 commands a linear solenoid 3 to open the suction air throttle valve 2 by 2/10 from its fully closed condition. At idling after the start of the engine, suction air is throttled with the throttle valve opened by 2/10, thereby providing the aid for reduction in noise and vibration. Once an accelerating pedal is stepped on for driving, an acceleration switch is turned ON so that the computer 5 commands the linear solenoid 3 to fully open the suction air throttle valve 2. Hence, the vacuum pump may be excluded.

SOLUTION: After a flow feature and a nozzle hole 16 are formed of a polymeric material 18, a nozzle plate 10 is set to a semiconductor substrate 20 including an ink propeller device 22 such as a resistor heating ink in a projection chamber 14, etc. When the ink is heated by the ink propeller device 22 of a resistor type, components of the ink are evaporated rapidly to generate bubbles of steam. The bubbles formed in the projection chamber 14 press a part of the ink out from the projection chamber 14 through the nozzle hole 16. The ink collides against the semiconductor substrate 20. Since the bubbles of steam expand quickly in all directions, the bubbles extrude the ink also from a feed path 12.
