Title: Gas discharge display driving circuit
Inventor: YAO SHINPEI
IPC: G09G3/291
Filed: 1990-09-19
Abstract: PURPOSE:To easily integrate the driving circuit even when the number of electrodes increases by providing an output buffer part which precludes mutual interference between a selective display driving part and a holding voltage driving part. CONSTITUTION:The circuit is provided with the selective display driving part 1 which applies a select pulse to a specific selected electrode of a gas discharge display panel 7 to write or erase display data, the holding voltage driving part 2 which applies a holding voltage pulse to all electrodes to store the display data, and the output buffer part. The output buffer part 3 prevents the mutual interference between the selective display driving part 1 and holding voltage driving part 2 when applying the select pulse and holding voltage pulse. Thus, a holding voltage pulse supply part which is large in power consumption in the gas discharge display driving circuit is separated from the outside, so even if the number of electrodes increases at a request for the size increase of the display panel 7, the driving circuit can easily be integrated.

Abstract: PURPOSE:To increase an electrode in width and to attain high frequency application by providing a split type interdigital electrode whose electrode width is 3/8lambda, and a reflecting electrode digital array whose electrode width is 3/4lambda and gap width is 5/4lambda where lambda is the wavelength of a surface acoustic wave with respect to a desired resonance frequency. CONSTITUTION:The split type interdigital electrode 2 whose electrode width is 3/8lambda is provided onto the piezoelectric substrate 1 and the reflection electrode digital array whose electrode width is 3/4lambda and gap width is 5/4lambda is arranged at both sides. Since split type is adopted for the electrode digit 2, the surface acoustic wave of wavelength lambda is excited efficiently by using a ternary harmonic and since the reflector is arranged at each 2lambda, the surface acoustic wave of wavelength lambda is confined. Since the fundamental wave of the electrode digit 2 has a 3lambda of wavelength, it is cancelled in the reflector and not excited. Thus, the surface acoustic wave of wavelength lambda is excited and the electrode width is increased by 1.5 time (3/8lambda in comparison with conventional 1/4lambda) and high frequency application is attained.

Title: Driving circuit
Inventor: OKANO MASAMI
IPC: H01F7/18
Filed: 1987-10-02
Abstract: PURPOSE:To attain stable power supply control to a load by forming a feedback control loop for an operational amplifier through a by-pass circuit when a driving transistor (TR) is OFF. CONSTITUTION:Since the by-pass circuit 40 is connected even when the TR 4 is OFF, the feedback control loop based upon the operational amplifier 13 is formed and the voltage Vp' of the 2nd node P' is fed back, the operational amplifier 13 is not satisfied. Since the operational amplifier 13 is not satisfied and its output voltage is not high, the TR is not satisfied when the TR 4 is turned from OFF and ON in the succeeding time, overshooting with a large supply current Ia is not generated and the overshooting can be suppressed up to a negligible level. Consequently, stable power supply control to a solenoid 1 can be attained.

Title: Ring trip circuit
Inventor: WATAI TAKAHIRO
IPC: H04M3/02
Filed: 1988-09-30
Abstract: PURPOSE:To correctly and rapidly detect the response of a called party by providing a detecting threshold value generating means and a comparing means with a calling signal and detecting the response of the called party with a comparing output. CONSTITUTION:When a called party responds to a calling, the current closed circuit of a calling signal generator 3 is completed, and the impedance of a telephone set 2 is changed. The signal waveform on an A line is divided into positive and negative parts and rectified by half wave rectifying circuits 23 and 24. The output of a rectifying circuit 23 is peak-held, level-shifted in the positive direction, made into a threshold value and compared with the signal of a half wave rectifying circuit 24 with a comparator 27. Since the central level of a signal waveform is surely lowered from a ground level to a negative side after the off-hook, the peak of the waveform is larger than the detecting threshold value only for the changed part and the comparing output can be obtained. A resetting pulse to supervise the calling is generated from a pulse generator 28, inputted to R-SFF 29 and when the called party responds, the R-SFF 29 generates an 'L' level. By the constitution, by generating the detected value in accordance with the calling signal, the response of the called party is correctly and rapidly detected without being influenced by the line condition of a subscriber.
