Title: Method for driving brushless motor
Inventor: NAKAI MITSUHISA
IPC: H02P6/06
Filed: 1997-08-21
Abstract: PROBLEM TO BE SOLVED: To smoothly switch the operation mode of a brushless motor to a rotor position detecting operation mode from a synchronous operation mode, by setting the relation between the rotating speed of the motor in the synchronous operation mode and that of the rotor position detecting operation mode, so that the latter can become equal to or lower than the former. SOLUTION: A start command signal 151, a switching signal 152, and a duty ratio command signal 153 are simultaneously outputted from a microcomputer 15. Upon receiving the command signal 151, a synchronizing signal generating circuit 10 outputs a synchronizing signal 100 and a rotating magnetic field generating circuit 11 outputs signals 111-113 based on the signal 100. In the course of the above-mentioned operations, the synchronizing signal 100 and the duty radio command signal 153 in the synchronous operation mode and rotor position detecting operation mode of a brushless motor are set so that the rotating speed of the motor can become equal to or lower than that of the motor in the synchronous operation mode, when the operation mode of the motor is switched to the rotor position detecting operation mode from the synchronous operation mode.

IPC: F02M51/06
Filed: 1991-08-09
Abstract: PURPOSE:To reduce discharge of nitrogen oxide by performing proper auxiliary injection and main injection through simple structure without increasing the generation of noise. CONSTITUTION:A needle valve 17 is forced into pressure contact with a sheet surface 12a of a nozzle body 12 through a pressure pin 24 by means of the force of a pressure spring 26 and fuel fed with a pressure by the aid of a fuel injection pump is stored in a fuel reservoir chamber 18 on the periphery of a valve. When a pressure in the fuel reservoir chamber exceeds the press down force of a spring, the valve is separated away from a sheet surface to inject fuel to an engine. A free piston 27 brought into pressure contact with the upper end of the spring is vertically slidably located. A lamination type piezoelectric element 28 is brought into contact with the upper surface of the piston and further, by applying a voltage between terminals 28e and 28f of the piezoelectric element, the piezoelectric element is vertically expanded and contracted to change the elastic force of the spring. Based on detected outputs from sensors 31-33 to detect the running state of the engine, a controller 34 controls the piezoelectric element.
