Title: Optical scanner
Inventor: KOIDE JUN
IPC: G02F1/335
Filed: 1990-06-22
Abstract: PURPOSE:To execute the optical scan at a high speed and with high resolution by deflecting simultaneously plural pieces of light beams generated from plural pieces of light sources by a surface acoustic wave. CONSTITUTION:Three pieces of incident light beams intersect at a point A by a thin film prism 6. On the other hand, in the same A spot, a surface acous tic wave SAW of a progressive wave generated by a comb line electrode IDT 7 exists, therefore, the light beam is subjected to deflection in accordance with a reflecting condition of Bragg by an interaction with SAW and emitted. In this case, when a partial charge of an SAW generation frequency band of each IDT 7 is assigned, and also, the frequency of each IDT 7 is modulated, the reflecting condition of Bragg is varied in connection with a variation of the frequency of SAW in the A point, the deflecting direction is varied and a scan of the light beam is executed, The advance direction of SAW generated from each IDT is set so that he Bragg diffraction becomes maximum by a reference frequency of each IDT. In such a way, an optical scan of a high speed and high resolution which is impossible by being restricted physically conventionally can be executed.

Title: Electromagnetic proportional type pressure control valve
Inventor: MASUDA KENJI
IPC: F16K31/06
Filed: 1980-11-21
Abstract: PURPOSE: To stabilize the posture of a poppet and improve reproduceability of a predetermined pressure by insetting in the poppet an intermediate spring seat member inset in an actuator so as to slide freely along an axial direction.  
     CONSTITUTION: Another end portion of an intermediate spring seat member 32 is inset slidably into an axial hole 36 at the rear face of an poppet 3 and a large-dia portion 34a is inset slidably into an end portion of a push pin 23. Because the poppet 3 slides on the intermediate spring seat member 32 fitted onto the push pin 23 and guided to slide forward and backward during a pressure controlling, the poppet is aligned with a seat portion 14 and the alignment posture is kept constantly along the axial direction. Consequently a repeated control of the predetermined pressure causes a reproduceability of a certain pressure to be improved.

Title: Separating method of separating phenol
Inventor: SUZUKI HIROSHI
IPC: C02F1/58
Filed: 1978-12-29
Abstract: PURPOSE: To efficiently separate phenol, by adding water containing dissolved carbon dioxide to a waste liquid containing the phenol.  
     CONSTITUTION: Water, in which much carbon dioxide is dissolved under pressure, is added to a waste liquid which is produced in a phenol resin manufacturing plant, coke chemical plant, coal gas washer or the like and contains phenol. Neutralization is thus caused. The phenol is separated. The phenol is buoyed up by carbon dioxide bubbles generated in the water. The consumption of the carbon dioxide is lower and the pH level can be more easily adjusted in this method than in another method of supplying only carbon dioxide for neutralization. As a result, a phenol separation layer of high concentration is formed. The efficiency of work is high, and even a compact and simple structure thereof is satisfactory for the purpose.

Filed: 1985-07-26
Abstract: PURPOSE:To realize an absolute value circuit having satisfactory linearity even when a small signal is inputted by constituting the input and output transistors of a signal selecting circuit to use as an emitter follower circuit. CONSTITUTION:In the circuit block consisting of transistor groups Q5-Q8, etc., the collector electric current of an output transistor Q7 flows at a resistance R5 for detecting the electric current and the collector voltage of the transistor Q7 is changed.

Title: Television receiver
Inventor: ISOBE MITSUO
IPC: H04N5/62
Filed: 1981-10-15
Abstract: PURPOSE:To reduce the occurrence of distortion due to the video signals, by forming a 4.5MHz beat wave detector with a synchronism wave detector which is set independently of a video wave detector and then actuating said beat wave detector with a phase axis which is relatively different from a video IF carrier wave by about pi/2. CONSTITUTION:The 1st output signal (fv2') of a voltage control oscillator 333 has a relative phase difference of about pi/2 to the carrier component of a video IF signal applied to an input terminal T2. The output signal of a multiplier 334 is led to an output terminal T3 via an amplifier 335. The DC component of the output signal of the amplifier 335 is applied to the oscillator 333 as the control voltage via an LPF 336. Thus a phase control loop is formed. The 4.5MHz beat signal produced at the terminal T3 is due to an integrating operation of an audio IF signal and a synchronizing carrier wave reproduced by the phase control loop. Thus a TV picture receiver receives just an extremely small degree of distortion.

IPC: F28D15/02
Filed: 1985-07-26
Abstract: PURPOSE:To reduce the heating amount in an accumulator as well as the power of a pump by reheating circulating liquid from a radiator to the accumulator with steam stream from a heat receiving section. CONSTITUTION:High-temperature vapor 3B, generated in the heat receiving section 1, flows to the radiator 2 through a pipeline 4A and a flow path 23 in a heat exchanger 21, and is condensed by cooling. Liquid 3A, whose temperature is lowered, passes through the pipeline 4B and the flow path 22 in the heat exchanger 21 while the temperature thereof is raised by heat received from the high-temperature vapor 3B in the flow path 23, thereafter, flows into the accumulator 7 through the pipeline 8D. Next, the accumulator 7 is heated when a thermoelectric element 13 is switched over and the liquid, whose temperature has been raised is changed into vapor. As a result, the internal pressure becomes higher than the pressure in the heat receiving section1 nd liquid in the accumulator 7 is discharged into the heat receiving section 1. Accordingly, the circulation of the liquid may be generated even in case the amount of input electric power of the thermoelectric element 13 is small.
