Title: Controller for system equipped with prime mover and hydraulic pump
Inventor: IZUMI EIKI
IPC: F02D41/14
Filed: 1984-06-18
Abstract: PURPOSE:To improve fuel consumption and operation performance by using a prime mover in a low-revolution and low output range when the load applied into a hydraulic pump is small, and by increasing the number of revolutions as the load increases, and then by using the prime mover in a high revolutions and high output range. CONSTITUTION:If the load of a hydraulic pump 3 is small, when the instructed revolution-speed signal Nso for a relatively low revolution speed is instructed by a fuel throttle lever 5, the output revolution-speed signal N of a prima mover 1 and the instructed revolution-speed signal Nso are early equal. Therefore, Nso is set as an aimed revolution-speed signal No, and the fuel injection amount of a fuel injection pump 2 and the discharge amount of the hydraulic pump 3 are controlled. When the load of the hydraulic pump 3 increases in this state and the output revolution-speed signal N reduces, the revolution-speed deviation DELTAN increases, and when DELTAN exceeds a set value (a),an increased revolution-speed signal Nn is generated from an increased revolution-speed generator 12. Then, the signal Nn is added 13 into the signal Nso, and the aimed revolution-speed signal No is corrected.

IPC: G11B7/135
Filed: 1989-05-17
Abstract: PURPOSE:To prevent the lowering of the accuracy of an error detection even when a light beam for reading is widely swayed for a track access by irradiating a reference track with a light beam for control in taking a positional correspondence with an information recording track to an optical recording medium. CONSTITUTION:A light branching means to separate one part of a waveguide light from components to be diffracted and deflected by surface acoustic waves 15 and 16 and to guide it in a definite direction as a light beam L4' for control is provided, the light beam L4' for control for detecting a focus error and a tracking error is separated from a light beam L4 for reading recorded information, and the reference track is irradiated by the light beam L4' separately. Contrary to that the light beam L4 for reading is successively deflected for the track access, the light beam L4' for control is not deflected in such a way. Consequently, the light beam for control reflected at the reference track is not swayed on the light-receiving surface of a photodetector for detecting an error. Thus, the photodetector does not need to be formed especially long, and the lowering of the error detection accuracy can be prevented.

Title: Muting circuit for pulse width modulation amplifying system
Inventor: KOURIKI YOSHIROU
IPC: H03G3/34
Filed: 1980-09-08
Abstract: PURPOSE:To suppress the pop sound low with high speed operation, by providing a switching means for muting which interrupts the transmission of a pulse train signal to the next stage on an output line of a pulse width modulator. CONSTITUTION:Between an output line 21 of a pulse width modulator 2 and ground, a muting circuit consisting of switching transistors (TR) Q1-Q3 is provided. When a muting signal to the base of the TRQ1 is at a low level, the TRs Q1-Q3 are turned off, and the output pulse train signal of the modulator 2 is transmitted to a pulse width modulation amplifier. When the muting signal is at high level, the TRQ1 turns on and the emitter current flows to the base of the TRQ3 via the TRQ2 to turn on the TRQ3 and to clamp the line 21 to ground potential. Thus, no pulse train signal is supplied to the next stage pulse width modulation amplifier for muting. Since the circuit 6 consists of an electronic circuit, the speed is high, and since the muting is not made at the input side of the circuit 2, pop sound can be suppressed lower.

Abstract: PURPOSE: To cause gas-liquid contact reaction and improve the removing efficiency of furfural by causing counter-current contacting of a furfural exhaust gas with an aqueous sodium bisulfite of the specific pH.  
     CONSTITUTION: An exhuast gas contg. furfural is led into a washing tower 2 via a duct 1. On the other hand, an aqueous sodium bisulfite soln. of 4.5W6.5 pH value range stored in a circulating liquid tank 5 is sprayed from nozzles 4 through a pump 6 and a conduit 7, whereby it is caused to make countercurrent contact with the exhaust gas. The aqueous soln. is then returned into the circulating tank and is replenished with sodium bisulfite, after which it is again force-circulated by the pump 6. If necessary, the treated gas is treated in the secondary washing towar of the similar system via a duct 3 and the slightly remaining furfural is passed through an adsorption tower packed with active carbon, whereby it is completely removed. The pollution-free exhaust gas is released into the air. The reason for specifying pH is: At above the upper limit, the absorption efficiency decreases and below the lower limit, a large amount of SO 2  gas will be produced.
