Title: Buffer amplifier
Inventor: MIZUGUCHI HIROSHI
IPC: H03F3/45
Filed: 1981-02-16
Abstract: PURPOSE:To decrease the difference between input and output voltages to a very small value, by the power feeding control so that the potential difference between the potentials at input and output terminals can be zero, with the output of a differential amplifier controlled with the output of a differential amplifier connected between input and output terminals. CONSTITUTION:MOS transistors (TR)5, 6 and 8a, 10 respectively constitute the differential amplifiers, TR13 and resistor 14 constitute the constant voltage circuit and TRs 7, 12 constitute the constant current source. Further, TR8a can be controlled so that the input voltage fed between the input terminal 1 and the minus side power feeding terminal 4 (or, plus side power feeding terminal 3) and the output voltage appeared between the output terminal 2 and terminal 4 (or, terminal 3) are always equal. With a load connected between the terminals 2 and 4, when the potential at the terminal 1 is increased than that at the terminal 2, the drain current of TR5 is decreased and that of TR6 is increased. As a result, the drain current of TR8a is rapidly increased and the potential difference between the terminals 1 and 2 is kept zero. It is kept the same when the potential at the terminal 1 is dropped.

Inventor: NAKANISHI YASUHIRO
IPC: F15B11/00
Filed: 1996-02-08
Abstract: PROBLEM TO BE SOLVED: To improve the working efficiency by setting driving force (excavating force) and working speed to conditions suitable for the work of a wheel loader. SOLUTION: This device has a combining piping 18 having pumps 2, 3 driven by the same prime mover 1, which combines the discharge pressure oils of the pumps 2, 3. A wheel loader having a shift down switch 19 for shifting down a transmission gear from second speed to first speed has a selector 24 for laying one pump 3 into unload state in interlocking with the input operation of the shift down switch 19. Thus, when a operator shifts down the transmission gear from the second speed to the first speed by the input operation of the shift down switch 19, the one pump 3 is laid in the unload state, whereby a high driving force can be provided. When the unload state is released in interlocking with the operation of switching the transmission gear to neutral or backward, the following operation can be quickly performed.

IPC: H01L27/146
Filed: 1983-02-14
Abstract: PURPOSE:To improve the resolution by providing a gate electrode on the surface of a substrate between diode regions of a photo diode array via an insulation film. CONSTITUTION:In the photo diode array wherein p type regions 2 are formed in the n type substrate, windows are opened in an oxide film 3 on the surface, and electrodes 4 for leading out signal are provided, the gate electrode 13 is adhered on the surface of the substrate 1 between said regions 2 forming the diode via the gate oxide film 12.

Title: Picture signal compression coding device and picture signal companding system
Inventor: WATANABE MIKIO
IPC: H04N19/625
Filed: 1989-02-02
Abstract: PURPOSE:To normalize in response to a picture, to eliminate the need for a divider an to simplify the device by multiplying a reciprocal of a normalized coefficient in the normalization after orthogonal conversion so as to apply normalization thereby. CONSTITUTION:A reciprocal 1/alpha of normalized coefficient alpha is obtained and the reciprocal 1/alpha is multiplied with a reciprocal T<-1> of a present weighting table T to obtain 1/alphaT. Thus, a normalizing section 16 multiplies the value 1/alphaT with the conversion coefficient to attain the normalization similarly to the case with the division by the value alphaT. Since the normalizing coefficient alphais set in response to the picture, the normalizing by the normalizing coefficient in response to the frequency component of the entire picture is attained. Since the normalizing is applied by multiplying the value 1/alphaT with the conversion coefficient, it is not required to use a divider in the normalization difference from the division by alphaT. Thus, the device is formed with simple constitution.

In this case, the thicknesses A, B of the 1st and 2nd recess parts 24, 25 are adjusted respectively experimentally and the pressure is adjusted to the metallic core wire 4 of the coated metal 5. In other words, the quantity of eccentricity of the core wire 4 is measured by the state of the ununiform section obtained experimentally to set the thickness of each recess part 24, 25 according to the quantity of eccentricity. In this way, since the pressure of the coated metal 5 acting on the metallic core wire 4 can be balanced, ununiform sections are prevented from occurring on the composite line of the product.

Abstract: PURPOSE:To compensate unfavorable influences due to the delay in a signal transmission and the deterioration of a waveform by detecting the transmission delay quantity of a signal from a camera head to a signal processing part and controlling the timing of the signal processing circuit with the detecting output. CONSTITUTION:A camera head 10 and a signal processing part 12 are connected by a cable 14.

Abstract: PROBLEM TO BE SOLVED: To remove the influence of an inner charge current and get an accurate differential current in line with actual state by computing the inner charge current from the quantity of actual system input, and using the value computed here. SOLUTION: A differential current making means 103 computes a charge current influenced by leakage capacitance from the differential current of each- phase current of each terminal, on the basis of the vector of each-phase voltage, and stores this and each-phase voltage at computation of charge current described above.

IPC: F02M23/08
Filed: 1989-02-01
Abstract: PURPOSE:To make the continuation of low-speed driving performable even in case of being locked to a high-speed corresponding mode by installing an on-off valve which interrupts the interconnection of a passage in response to a means, detecting a fact that an operating state of a valve system comes to high-speed correspondence in a low-speed driving range. CONSTITUTION:When each transfer pin comes into a sticking or binding state at a high speed mode due to malfunction in a hydraulic system or nonconformity in a return spring and so on, a cam profile of a high-speed cam is set so as to make a valve operating angle relatively larger so that blow-by and spitting of intake air occur at low speed driving and thereby maintenance of this low speed driving gets difficulty. In order to maintain engine driving in a suchlike state, there is necessary to increase an air flow rate relatively. Accordingly, there is provided with an auxiliary air passage 15 to bypass a throttle valve 6, and an auxiliary air valve 14 being opened or closed in response to inlet negative pressure is installed in this passage.
