Title: Television tuner
Inventor: OISHI TAKESHI
IPC: H04N5/44
Filed: 1985-03-22
Abstract: PURPOSE:To prevent variance in characteristics of a varactor diode from exerting an adverse influence upon the performance of a television tuner by varying a control voltage impressed to the variable capacity element of a tuning circuit and also varying the gain of a high frequency amplifier so that the input signal level of the high frequency amplifier does not exceeds a saturation level. CONSTITUTION:The high frequency amplifier 3 decreases in gain by a constant extent when an input signal is too large. A host computer 27 calculates the value of an offset voltage supplied to a D/A converter 30 and either of D/A converters 31 and 32 and adds the calculated offset voltage data of data of the D/A converter 30 and either of the D/A converters 31 and 32. Then, the high frequency amplifier 3 is supplied from a control voltage from a high frequency AGC circuit 20 through an AGC controller 28 and returns to a normal operation state after tracking adjusting operation is all completed.

Title: Sheet material conveying device and image forming device
Inventor: KAWAKAMI HIDEAKI
IPC: B41J13/076
Filed: 1995-02-21
Abstract: PURPOSE: To suppress interference of a conveying roller with another member and to shorten the length of the conveying roller so as to accomplish compactification by arranging an engaging part, which is provided with an axial direction pressing face and a diametral direction pressing face, in the end part of the conveying roller and locking a spring member, which energizes the two pressing faces in the engaging part at the same time, in a fixed part of a device main body. CONSTITUTION: An end part of a conveying roller 10 is provided with a groove 30 serving as an engaging part having an axial direction pressing face 30a and a diametral direction pressing face 30b, and a non-coil type wire spring 17, which energizes the two pressing faces 30a, 30b in the groove 30 at the same time, is locked in a fixed part 39 in a device main body. In this way, a backlash in the axial direction and in the diametral direction of the conveying roller 10 can be eliminated by means of the single spring member 17, and consequently, not only a shift in the lateral direction but also a shift in the conveying direction are reduced in a recording sheet material, so that a recording position to the recording sheet material is decided, and printing precision can be improved. Therefore, the conveying roller 10 can be shortened in length, and a member projecting from the conveying roller 10 is dispensable, and as a result, compactification can be accomplished.

Title: A/d converter
Inventor: MATSUURA TAKEHISA
IPC: H03M1/38
Filed: 1987-03-13
Abstract: PURPOSE:To obtain a converter capable of measuring a voltage without lowering measuring accuracy even when the voltage exceeding the generation voltage of a D/A conversion circuit is measured, by deciding a most significant order bit by comparing a signal to be measured with the output voltage of a reference voltage, and setting a result as an offset voltage to a voltage comparison type comparator. CONSTITUTION:The voltage comparison type comparator sets decision whether an input signal Sa exceeds the reference voltage or not as the decision of the voltage of the most significant order bit by comparing the input signal Sa with the output voltage of a reference voltage generation circuit 3 via adder circuit 7, and when it is decided that the signal Sa does not exceed the reference voltage, a switching circuit 6 selects the output of the D/A conversion circuit 4, then applies a usual A/D conversion. When it is decided that the signal Sa exceeds the reference voltage, the circuit 6 remains unchanged. Therefore, the voltage in which the output voltage of the conversion circuit 4 is added on the reference voltage is supplied to the comparator 1, then, the A/D conversion is applied. For this reason, it is possible to provide a doubled measuring range without lowering the measuring accuracy on a usual device.

Title: Plasma display driving circuit
Inventor: MIMA KUNIHIRO
IPC: G09G3/296
Filed: 1999-03-05
Abstract: PROBLEM TO BE SOLVED: To suppress the increase of power consumption by connecting a diode in parallel with a low-side field effective transistor so as to prevent the destruction of a circuit element in the case of reducing time between pulses required for driving a high-definition panel. SOLUTION: A diode 51 setting a direction from first voltage to a first row electrode to be a forward direction is connected between the first voltage and a first row electrode. In addition, a diode 52 setting a direction from the first voltage to a second row electrode to be a forward direction is connected between the first voltage and the second row electrode. Namely a current flowing from the source terminal of the field effect transistor 6 to a drain terminal is caused to flow through the diode 51 and a current flowing from the source terminal of a field effect transistor 16 to a drain terminal is caused to flow through the diode 52. Thus, switching of the transistors 6 and 16 is accelerated to suppress abnormal current flowing through the transistors 6 and 16.

Title: Heat pump hot-water apparatus
Inventor: WATANABE TAKEJI
IPC: F24H1/00
Filed: 1993-03-18
Abstract: PURPOSE:To achieve high efficiency by providing a check valve for allowing refrigerant to flow in a direction opposite to a refrigerant circulation circuit between a four-way valve and refrigerant-water heat exchanger and providing an open/close valve for allowing refrigerant to flow in a direction of the refrigerant circulation circuit, by-passing the four-way valve and check valve. CONSTITUTION:Superheated refrigerant gas of high temperature and pressure delivered from a compressor 1 flows into a refrigerant-water heat exchanger 3 via an open-close valve 7, where water sent from a circulation pump 12 is heated by utilizing condensation heat of refrigerant and the water is stored in a storage tank 11. And pressure of the refrigerant condensed in the exchanger 3 is reduced at a pressure reducing device 4 and the refrigerant flows into an evaporator 5, where it absorbs heat of the atmosphere and is evaporated, which evaporated gas returns to the compressor 1 via the valve 2. When outdoor temperature falls in winter and frost attaches to the evaporator 5 and the temperature of refrigerant passing through the evaporator falls, flow direction of the valve 2 is changed over to a direction of broken line and the valve 7 is closed. As a result, the refrigerant gas delivered from the compressor 1 flows to the evaporator 5 via the valve 2, so that the frost is removed by means of condensation heat.

Title: Semiconductor logic circuit
Inventor: NOKUBO JIYOUJI
IPC: H03K17/0422
Filed: 1984-03-27
Abstract: PURPOSE:To avoid the saturation of an output transistor and to attain a high- speed switching action with an ECL type logic circuit, by adding a Schottky barrier diode. CONSTITUTION:The cathode of a Schottky barrier diode D is connected to the output of an output transistor TRQ with the anode connected to the highest potential VCC respectively. Thus the collector level of the TRQ is clamped by the diode D. This eliminates a fact that the TRQ is saturated by the noise voltage produced in a switching mode of the TRQ. This avoids the saturation of an output transistor and assures a high-speed switching action.

Abstract: PURPOSE:To decrease the average power consumption effectively and to improve the reliability, by stopping the operation of a sample circuit of a sample holder during the hold period. CONSTITUTION:The difference from a conventional sample hold circuit lies in that a samler operating pulse q(t) from a timing generating section 4 is led to a sample circuit 18.

To attain accurate sampling with a gate pulse p(t), an operating pulse q(t) having a sufficient pulse width is applied to flow the current of the current source forming the sample circuit. After the end of the sampling, the operation of the sample circuit is stopped again.
