IPC: H04B3/28
Filed: 1987-04-17
Abstract: PURPOSE:To reduce the deterioration in talking quality by connecting a high impedance means in series with a feeding loopback circuit of a feeding loopback station so as to reduce the effect of electromagnetic induction when a communication cable energized by one-way feeding system is subjected to electromagnetic induction from a high voltage power cable installed in parallel. CONSTITUTION:If a fault takes place in a 2nd feeding circuit 5 and one-way feeding is applied from a 1st feeding circuit 4, the 2nd feeding circuit having a function suppressing 50/60Hz components is disconnected and instead a current return is formed by a feeding loopback circuit 6 having no suppressing function. Since the 50/60Hz components are suppressed by the 1st feeding circuit 4 only, the suppressing effect is reduced and the talking quality is deteriorated. Then a high impedance means 7 giving a high impedance at 50/60Hz is connected in series with the feeding loopback circuit 6 to suppress the 50/60Hz components at the feeding loopback point in case of one-way feeding. Thus, the deterioration in the talking quality is improved.

IPC: H02P7/288
Filed: 1990-04-11
Abstract: PURPOSE:To prevent penetrating current by a method wherein a stable latch circuit, controlling the control signal of a pair of power elements exclusively, is formed in a bridge driver and the like for driving a motor when the conduction of current through the pair of power elements, connected in series, is controlled complementarily. CONSTITUTION:The conducting direction of current through a load RL is switched by controlling the conduction of current through transistors(Tr) Q1, Q2, connected in series to a power supply potential Vcc-GND, by a signal given to an input IN complementarily. When the input In is 'H', the control signal Vg2 of the Tr Q2 becomes 'L'. Accordingly, the output of a comparator 16 becomes 'H'. Accordingly, the control signal Vg1 of the Tr Q1 becomes 'H'. The output of the comparator 15 becomes 'L' accordingly and, therefore, the self retaining of the Tr Q2 is effected stably. When the input IN is switched from 'H' into 'L', the Tr Q1 is turned OFF at first. Subsequently, the control signal Vg2 is changed from 'L' into 'H'. Thus, Trs Q1, Q2 are prevented surely from being tuned On simultaneously.

Title: Monolithic microwave integrated circuit
Inventor: SAYANA TOMOAKI
IPC: H03F3/60
Filed: 1991-04-26
Abstract: PURPOSE:To improve the degree of integration of a semiconductor integrated circuit and to reduce a chip size by solving problems such as oscillation and deterioration in a gain flatness due to unexpected production of a feedback loop caused by coupling between lines in the case of suppressing coupling between two adjacent lines and forming especially a multi-stage amplifier and avoiding the feedback due to coupling without need for increasing the distance between wires.

Title: Horizontal synchronizing signal recovery circuit
Inventor: OIDE TAKAHIRO
IPC: G09G1/04
Filed: 1985-05-07
Abstract: PURPOSE:To recover a horizontal synchronizing signal with high accuracy even from any composite synchronizing signal by using a PLL with respect to the composite synchronizing signal thereby generating the horizontal synchronizing signal and applying free running to a VCO in the PLL around the disturbed vertical synchronizing signal period. CONSTITUTION:A horizontal synchronizing signal (HSC) recovery section consists of a PLL circuit. A composite synchronizing signal outputted by a synchronizing separator circuit 3 is used as a reference signal to the PLL. The composite synchronizing signal is the same as the HSC except the vicinity of the vertical synchronizing signal (VSC) period. Thus, the PLL outputs the HSC at the period. However, since the HSC differs depending on a personal computer or other device around the VSC period of the composite synchronizing signal, disturbance might take place. Then the vertical synchronizing separator circuit 4 stops the operation of a charge pump 7 near the period based on the VSC extracted from the composite synchronizing signal so as to make the VCO 8 run freely thereby excluding the adverse effect on the PLL near the VSC period.

Title: Photoelectric conversion circuit
IPC: H04B10/50
Filed: 1991-04-26
Abstract: PURPOSE:To extract selectively only an electric signal corresponding to a signal light from electric signals obtained by photoelectric conversion. CONSTITUTION:Electric signals obtained by photoelectric conversion by a photodiode 9 are supplied to a parallel resonance circuit 1. By setting the resonance frequency of the parallel resonance circuit 1 at the frequency of pulse modulation of a signal light beforehand, the parallel resonance circuit 1 makes a voltage drop occur only for the electric signal corresponding to the signal light, and therefore only the electric signal corresponding to the signal light is inputted to the gate of an NMOS transistor Q1. The electric signal amplified by the NMOS transistor Q1 is extracted from an output terminal 200. While AC components corresponding to lights other than the signal light are excluded, only the electric signal corresponding to the signal light can be extracted selectively. Since the amplification of the electric signal by the transistor is combined in this constitution, in addition, the extraction can be executed effectively.

Title: Power supply for electric vehicle
Inventor: KOBAYASHI MASAJI
IPC: H02M3/28
Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To reduce the capacity of a DC-to-DC converter and to prevent the charged state of sub-batteries from deteriorating by increasing the chances of fully charging them. SOLUTION: This power supply is provided with main batteries 3 for driving a drive motor 5, sub-batteries 8 for feeding power to low-voltage electric loads 9, and a DC-to-DC converter 7, which converts the voltage of the main batteries into voltages to be supplied to the sub-batteries and low-voltage electric loads. A current detector 10 detects the output current of the DCDC converter. As the output current increases, the output voltage of the DCDC converter is reduced continuously from a given maximum voltage capable of fully charging the sub-batteries to a given minimum voltage capable of operating the low- voltage electric loads. This design enables reduction in the capacity of the DCDC converter. When the output current of the DCDC converter becomes zero or small, its output voltage becomes high so that the sub-batteries are charged each time.  Thus, a situation will not occur in which sub-batteries fall into an insufficiently charged state.

Title: Method for controlling die swell of viscoelastic material in screw extruder with pin
Inventor: YANO MASASHI
IPC: B29C48/30
Filed: 1996-04-18
Abstract: PROBLEM TO BE SOLVED: To efficiently extrude a viscoelastic material under high precision die swell by setting a feedback system between the viscosity and temperature of the material detected by sensor pins attached at the end of a screw and the insertion rate of numbers of work pins. SOLUTION: Forefront pins 5a-5f closest to the end of a screw on the extrusion head 7 side are sensor pins for detecting the properties of a viscoelastic material. Hydraulic mechanisms 9-1-9-8 carry out operation to make work pins 4-1-4-8 freely movable on the inside and the outside of the radial direction of a screw 2 on the basis of the feedback command of the viscosity and temperature of the material which are detected independently by the sensor pins 5a-5f. The operation individually controls the insertion depth of the work pins 4-1-4-8 into the material by the feedback signal while the extrusion work of the material continues. The insertion depth is based on the distance between the inside wall of the cylinder and the bottom of the screw and expressed by an insertion rate.
