Title: Valve characteristics control device for internal combustion engine
Inventor: NIHEI HIROAKI
IPC: F01L1/34
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To enable changeover to a high lifting cam profile causing torque fluctuation, without increasing hydraulic sources nor deteriorating controllability in an internal combustion engine which has both valve lift adjusting mechanism and valve timing adjusting mechanism. SOLUTION: When an intake valve 11 is opened and closed by selecting a high lifting cam as an intake cam 15, engine performance due to variation of a valve timing is not so improved. On the other hand, it is necessary to attain delicate hydraulic balance in order to hold an intermediate position of a ring gear for determining a valve timing. The hydraulic pressure inside one hydraulic chamber should be increased simply in order to keep the most displaced position. The keeping force can be increased. When the high lifting cam is selected, the ring gear is previously kept at the most displaced position. In such a case, hydraulic pressure is supplied only to the hydraulic chamber on the side for displacing the ring gear to the most displaced position, for ascertaining the fixation of the ring gear.

Title: Electroacoustic transducer
Inventor: YONEYAMA MASAHIDE
IPC: G10K15/02
Filed: 1984-03-26
Abstract: PURPOSE:To obtain the value of an optimum parameter for obtaining high reproduced sound pressure of a secondary wave by selecting the ultrasonic wave frequency of a carrier within a specific range and setting the initial sound pressure level of an unmodulated carrier ultrasonic wave within a fixed range. CONSTITUTION:The maximum frequency of a modulated wave which is considered as to a parametric speaker is fm=20kHz, and fm=8kHz is sufficient for only a voice wave containing no instrument sound component. The range of the primary wave frequency optimum for the parametric speaker is f=25-40kHz. The optimum value of the primary wave initial sound pressure in this case is >=150dB. Cavitation, however, occurs almost at 160dB, so the propagating wave motion equation of a finite amplitude wave does not hold any more. Therefore, the optimum value of the initial sound pressure is 150-155dB. The maximum sound pressure of the secondary wave is therefore about 110-120dB.

Title: Controller for brushless motor
Inventor: NAGASE NORIYOSHI
IPC: H02P6/18
Filed: 1999-03-05
Abstract: PROBLEM TO BE SOLVED: To increase following-up capability for a phase change if a rapid change in rotational speed occurs, by detecting the discrete value of a counter from an energizing-phase switching point to a zero cross point, and switching the phases of respective commutator elements at the time when the counter counts by the discrete value from the zero cross point. SOLUTION: A counter 135 operates on the output signal of a counter- operation switching part 131 in a computing control 130. The counter 135 clears a discrete value to zero at an energizing-phase switching point, starts counting operation in a count-up mode, switches to count-down mode at a zero cross point, and outputs a flag signal when the discrete value becomes zero. As energizing switching part 131 receiving a flag signal switches the commutator elements 106-110 of a drive circuit 104, and the energizing phase of a stator 102. It is thus possible to switch the energizing phase stably regardless of rotational speed, thereby enhancing following-up capability of the phase for a change in rotational speed.
