Title: Acoustic signal processing circuit
Inventor: AKAGIRI KENZO
IPC: H04R25/00
Filed: 1987-12-04
Abstract: PURPOSE:To satisfactorily suppress an unnecessary signal with a simple constitution by detecting the time change component of an input acoustic signal and controlling the input acoustic signal when such a detecting value goes to an arbitrary comparing level or above. CONSTITUTION:An acoustic signal from an input terminal 1 is extracted through a delaying circuit 2 and a multiplier 3 to an output terminal 4. The acoustic signal from the terminal 1 is supplied to an envelope detecting circuit 5, such a detecting signal is supplied to a difference circuit 6, and the time change component is obtained. The time change component is supplied to a comparator circuit 7, and it is compared with the arbitrary comparing level from a terminal 8. Thus, when the time change component is larger than the comparing level, an impulse is generated from the comparator circuit 7. The impulse is supplied to a time constant circuit 9, a waveform is smoothed, the smoothed signal is polarity-inverted and offset by a converting circuit 10, and it is supplied to the multiplier 3. Thus, the level of the input signal is lowered, and the external noise can be suppressed.

Title: Controller for pwm control inverter
Inventor: SATO SHINJI
IPC: H02M7/537
Filed: 1995-11-27
Abstract: PROBLEM TO BE SOLVED: To suppress the distortion of output waveform at the time of two- phase modulation and to ensure the minimum pulse width of PWM signal. SOLUTION: When a voltage reference generator 1 generates a three-phase voltage reference VU*, VV* and VW* and a switching pause command generator 4 generates commands AU, AV, AW, AX, AY and AZ for temporarily stopping the switching of an inverter depending on the voltage reference, a voltage reference corrector 8 stops the switching in the relevant section of a phase having the switching pause command. Furthermore, a voltage reference inputted during the relevant section of other phase is corrected and the three-phase voltage reference from the voltage reference generator is outputted, as it is, for a section where the switching pause command is not present to produce a corrected voltage reference VU***, VU*** and VW***. A comparator 3 compares the corrected voltage reference with a carrier (h) to produce a PWM control signal.

Title: Method for driving liquid crystal optical element
Inventor: FUJIMURA HIROSHI
IPC: G02F1/133
Filed: 1986-12-26
Abstract: PURPOSE:To sufficiently illuminate a liquid crystal optical element and to obtain excellent temperature characteristics by repeatedly impressing a high frequency electric field to a liquid crystal material during a writing period and impressing a low frequency electric field during one period in the repeated high frequency field impressing period. CONSTITUTION:A selecting period T1 consists of periods T3-T6, and in the case of an ON signal, a high frequency field fHL is impressed to the periods T3, T5, a low frequency field fL for temporarily turning off a shutter is impressed to the period T4 and a superposed electric field fHL for holding the ON state is impressed to the period T5. When the high frequency field is repeatedly impressed and the low frequency field is impressed during the period, a liquid crystal shutter is repeatedly turned on and off. Consequently, the total ON period is prolonged and the quantity of light is increased, and since the low frequency field is impressed in a short period, the influence of a hysteresis effect based upon the high frequency field is reduced and the temperature characteristics can be improved.
