Title: Speed control of brushless motor
Inventor: NITTA YUJI
IPC: H02P6/06
Filed: 1989-11-29
Abstract: PURPOSE:To improve operating efficiency by a method wherein the amount of delay of a Hall sensor signal for detecting the number of rotation is con trolled to regulate a counter electromotive force and apply speed feedback when the number of rotation of a brushless motor is fluctuated from a set number of rotation. CONSTITUTION:Until a motor 1 is started and the speed of the same arrives at a set number of rotation, a Hall sensor signal 7 from a signal delay control circuit 3 is advanced to the maximum limit (EMF minimum) of the control range of the same by a PLL acceleration commanding signal 4 from a motor controller 2 of PLL control to effect the feedback of a delay Hall sensor signal 8 into the controller 2. When a set number of rotation is achieved, the Hall sensor signal 7 returns to an initial timing position (EMF maximum) by a PLL deceleration commanding signal 5 from the controller 2 whereby the motor 1 is decelerated. The amount of delay of a delay Hall sensor signal 8 is con trolled depending on whether the number of rotation of the motor is higher or lower than the set number of rotation to apply feedback. According to this method, a power consumption upon stationary operation may be saved.

Abstract: PROBLEM TO BE SOLVED: To identify a display part even upon the occurrence of a power failure, and ensure low power consumption by applying the constitution that a light source to emit light capable of exciting a phosphor having a persistence characteristic is laid at least at one position of the edge of a photoconducting board. SOLUTION: The prescribed pattern of display part is drawn on the back of a photoconducting board 1, using a phosphor 2 having a persistence characteristic. Also, a light emitting diode as a light source 3 to excite the phosphor 2 of the display part is buried in the edge of the photoconducting board 1. Furthermore, the edge of the photoconducting board 1 is coated with a white substance and a reflector 4 is thereby formed. The phosphor 2 forming the display part, when in contact with light from the light source 3, is excited and emits light. In this case, the emission of light due to photo-excitation continues over a certain time, even when the light source 3 stops emitting light.  Also, the display part continues to emit light, while gradually lowering brightness until the next lighting of the light source 3, even when the light source 3 is intermittently turned on for a short time. According to this construction, the lighting time of the light source 3 can be shortened by applying a timer function.

Title: Vehicle internal combustion engine suitable for remote starting
Inventor: TAKEMURA HIROKI
IPC: B60R16/023
Filed: 1996-11-20
Abstract: PROBLEM TO BE SOLVED: To retain the structure of a vehicle stopping device to jointly use the remote starting device of an internal combustion engine. SOLUTION: The immobilizer controlling means 23 of a vehicle electronic device 21 allows the operation of an internal combustion engine 30 only when a resonance signal from an oscillating and detecting means 28 conforms to a specific signal. When a remote starting command signal is given from a transmitter 33 outside a vehicle, a starter controlling means 31 breaks any of lead wires 43, 53, and 54 between the means 28 and 23 at first, to prohibit feeding the resonance signal to the lead wires 53 and 54. Then a starting signal from the means 23 to the means 28 is introduced to be synchronized, and successively a dummy resonance signal expressing a specific signal is created to be given to the means 23 via the lead wires 53 and 54.  When the dummy resonance signal express the specific signal, the means 23 can allow starting the engine 30, thereby jointly using vehicle stopping action and remote starting action without increasing an input and output terminal for the signal to the means 23.
