Title: Treatment of blow-out poisonous gas from safety device
Inventor: MORITA MASAHARU
IPC: B01D53/34
Filed: 1978-06-23
Abstract: PURPOSE: To make poisonous gas harmless by an exact and rapid treatment in which gas and absorption liquid are mixed by driving the absorption liquid necessary for removing poisonous gas by utilizing the pressure energy of gas stored in a high pressure gas facility and also operating safety valve.  
     CONSTITUTION: The poisonous gas of the high-pressure gas facility 1 starts to blow when its pressure becomes higher than the set pressure of the safety valve, and the blow-off poisonous gas from the valve 2 is reduced its pressure and reaches the ejector 4 while blowing out the gas staying in the releasing tube 3. And, the suction chamber 4b becomes negative pressure by the gas spouting from the driving nozzle 4a of the ejector 4 and thereby the liquid in the absorption liquid tank 6 is sucked up through the suction tube 5. When the poisonous gas reaches the ejector 4 and then absorbed in the absorption liquid with the aid of the diffuser 4c, the total volume of gas phase and liquid phase is reduced, whereby the negative pressure of the suction chamber is increased and the gas absorbing capability of the absorption liquid is increased. Thus, the exact and rapid detoxicating treatment of poisonous gas can be attained.

Title: Pll variation compensator
Inventor: TSUJI SEIZO
IPC: H03L7/087
Filed: 1988-03-29
Abstract: PURPOSE:To stabilize the output frequency and phase shifting characteristics of the title device even when the characteristics of a circuit element fluctuate due to changes in environment, such as temperature, humidity, etc., and conditions, such as power supply, etc., vary in a circuit by providing a voltage- controlled oscillator, plural phase comparators, etc. CONSTITUTION:The output of a voltage controlled oscillator(VCO) 1 is inputted to the 1st phase comparator 12 and an inverter 11 and signals having the opposite phase of the output of the VCO 1 are, supplied to the 2nd phase comparator 13. A comparator 14 takes the difference signals of the outputs of the comparators 12 and 13. Then the signals from which environment varying elements are removed of the phase comparing stage are supplied to a loop filter 7. Therefore, phase-compared outputs to which varying factors of the detecting stage related to the variation of temperature, humidity, power supply, etc., can be supplied to the VCO 1 through an adder 8 and amplifier 10. Since, by providing a sub-loop which compensates the variation of the phase comparing stage it self, influences of the varying factors at the phase comparing stage can be reduced, PLL outputs can be stabilized in frequency and phase.

Title: Multitube type heat exchanger
Inventor: KOMATSU ATSUSHI
IPC: F28F9/18
Filed: 1980-06-06
Abstract: PURPOSE: To decrease the stress remaining and stress concentration in the multitube type heat exchanger used in an atomic power plant and the like by providing an annular groove in the vicinity of the opening end of a tube hole of a tube plate at such a position as opposes the outer periphery of a heat transmission tube and welding sealingly the tube plate and heat transmission tube.  
     CONSTITUTION: The tube plate 1 is constituted by a tube plate element 11 and a tube plate battering 12 welded to the surface of the element 11 on the welding side. In the vicinity of the opening end of the tube hole 9 of the tube plate 1, there is provided the annular groove 13 the diameter of which is larger than that of the tube hole 9. The end of the tube 2 and the tube plate 1 are welded at a seal welding part 3. With such a construction, if gas in the vicinity of a root part is heated and expanded by the welding heat, the provision of the annular groove 13 prevents an increase of pressure. This is very advantageous in that any metal piece produced in the welding can be prevented from scaterring and that a generation of blow hole can be minimized.

Title: Method of controlling torque of brushless motor
Inventor: ITOU HISAYASU
IPC: H02P6/06
Filed: 1978-06-23
Abstract: PURPOSE: To simplify the control circuit of a brushless motor by controlling the torque of the motor under the control of drive currents flown through the respective phases.  
     CONSTITUTION: A brush angle γ is provided by a torque instruction 4 for an angle signal 3 detected by a position detector 2 directly coupled to the rotor of a brushless motor 1 to thereby produce a drive signal 6 indicating that the phase is displaced by γ from the signal 3. This drive signal becomes a drive current 8 by a current control power amplifier 7 to energize the windings of the respective phases of the motor 1. Thus, it does not control the absolute value of the current in the power amplifier, but control the phase of the angle signal of the rotor thus detected by the position detector. Accordingly, it does not necessitate a multiplier, but can simplify the control circuit.

Title: Optical deflection device
Inventor: SETO MASANORI
IPC: H04N1/23
Filed: 1985-04-11
Abstract: PURPOSE:To prevent a defect in picture quality from occurring by providing a sensor consisting of a light emitting part which irradiates plane mirror surfaces of a rotary polygon mirror with light and a photodetection part which photodetects reflected light. CONSTITUTION:The angle of incidence of light with which a plane mirror surface 2a of the polygon mirror is irradiated from the light emitting element of the sensor 11 varies according to the rotary movement of the plane mirror 2a. When the angle of incidence on the same plane mirror 2a deviates from said specific angle range as the rotation advances, the photodetecting element is not irradiated with the reflected light any more. Namely, the light emitting element is placed in a light emitting state during the driving of a motor 3 at any time to output pulses as many as plane mirrors 2a by the photodetecting element in every turn of the rotary polygon mirror 2, and respective pulses are outputted at invariably equal intervals as long as the motor rotates at a constant speed. For the purpose, the rotation of the motor 3 is controlled to scan the laser beam at a constant speed. Consequently, a defect in picture quality is prevented from occurring.
