Title: Driving device for vibration actuator
Inventor: GONDA TSUNEMI
IPC: H02N2/00
Filed: 1997-09-01
Abstract: PROBLEM TO BE SOLVED: To finely or intermittently drive a vibration actuator with an inexpensive constitution by controlling the relative motions of a vibrator by alternatively impressing a plurality of frequency signals having different phases and a plurality of frequency signals having the same frequency upon an electromechanical conversion element for driving. SOLUTION: A phase shifter 3 outputs a signal S1 which is shaped in a rectangular wave by controlling an oscillation frequency by using an input voltage by means of a VCO 2 as two signals S2 and S3 having phases which are shifted from each other by π/2. An exclusive OR gate 4 decides the driving direction of a vibration actuator 1 by deciding the phase to be shifted. Amplifiers 5 and 6 amplify the output signal of a switching circuit 9 to the driving level of the actuator 1 and impress the amplified signals upon the piezoelectric element of the actuator 1 as A- and B-phase signals. The signal used as the B-phase signal is switched between the signals S2 and S3 by means of switching circuits 8 and 9.  Since the actuator 1 is intermittently driven by switching the phases of the A- and B-phase signals impressed upon the actuator 1 to the same phases and opposite phases at prescribed intervals, the actuator 1 can be driven finely.

Title: Analog switch
Inventor: SAIKI EISAKU
IPC: H03K17/687
Filed: 1986-10-06
Abstract: PURPOSE:To apply the titled switch to opening and closing of a signal large in amplitude, as well, by connecting in series two N-MOSs, and applying a reference voltage to its connected part through a resistance. CONSTITUTION:A P-MOS 2 and N-MOSs 3, 4 which are connected in series are connected in parallel, and a substrate potential of the P-MOS 2 and a substrate potential of the N-MOSs 3, 4 go to VDD and VSS, respectively. Subsequently, to a connecting part (a drain or a source) of the N-MOSs 3, 4 which have been connected in series, a reference voltage VREF is applied through a resistance R 10. In case of a signal potential of a gate G1 VSS, and a signal potential of G2 VDD, an analog switch turns on, on the other hand, in case of the signal potential of G1 VDD, and the signal potential of G2 VSS, the analog switch turns off. In such a case, relation of the respective potentials goes to VDD> an input voltage >VSS. In such a way, a potential difference applied between the source and the drain of one N-MOS can be reduced, therefore, the signal amplitude can be made large by enlarging a dynamic range and an S/N is improved, and also, a problem of breakdown strength (BVDS) between the drain and the source of the N-MOS can be obviated.

Title: Cmos input buffer circuit device
Inventor: KAWANO TETSUJI
IPC: H03K3/353
Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: To easily realize the selection of a conventional input buffer circuit or an input buffer with Schmitt trigger depending on the situation. SOLUTION: A signal received by an input terminal IN is fed to a selector circuit IC via a conventional input buffer circuit IA and an input buffer IB with Schmitt trigger. The selector circuit IC selects an output signal from the conventional input buffer circuit IA and provides it to an output terminal OUT when a signal of a control terminal C is at a prescribed level (e.g. L level). On the other hand, the circuit IC selects an output signal of the input buffer IB with Schmitt trigger and provides it to the output terminal OUT when the signal of the control terminal C is at a level inverse to a prescribed level (e.g. H level). Thus, both the input buffer circuits IA, IB are tused depending on the status even after a mask is generated by using the signal fed from the control terminal C.

Title: Thermosensitive head
Inventor: HIGETA KAZUYA
IPC: B41J2/335
Filed: 1984-11-12
Abstract: PURPOSE:To obtain a thermosensitive head which is highly capable of responding thermally by applying an optimum value of thickness of a glazed layer. CONSTITUTION:The thermal response of a thermosensitive head mainly depends on the thickness of a glazed layer. If the glazed layer is too thin, a peak temper ature obtained is not at high level, showing a curve A. On the contrary, if the layer is too thick, a cooling speed is low although the peak temperature is high, thus showing a temperature change as shown by a curve B. If any moderate thickness between A and B of the glazed layer is selected, an optimum condition such as shown by a curve C is obtained. If it is assumed that the temperature conductivity of the glazed layer is k(m<2>/s), the printing cycle to(s) and the energization time tp(s), the optimum thickness delta(mum) of the glazed layer will be 1.3sq. rt. ktpX10<6=delta<=1.5sq. rt. ktoX10<6> but 1X10<-8=k<=1X10<-6>, 0.0002<=to<=0.005, 0.1to<=tp<=0.4to.

Filed: 1991-09-19
Abstract: PURPOSE:To obtain the high yield of stepped wiring in a lift-off process by making the width of the whole or part of the stepped wiring, excluding that on the top of a mesa embracing a diffused region, larger than the latter. CONSTITUTION:A silicon nitride film 8 as a passivation film and a surface antireflection film is formed on the surface of an element by the plasma CVD. Then the p-side electrode 9 and the n-side electrode 10 are formed. The p-side electrode is so constructed that the contact electrode in the P<+> region 5 is connected with the pad electrode through stepped wiring. The width of this stepped wiring is 5mum on the mesa 6 embracing a light receiving part and 10mum in other parts. The width of 5mum is to reduce the parastic capacitance occurring between the wiring and n-InP 4 via the silicon nitride film 8 and the width of 10mum is to prevent the breaking of steps in a lift-off process. This improves the yield without increasing the parastic capacitance.
