Title: Steam pressure controller for turbing bypass
Inventor: OOKAWA KATSUYA
IPC: F01D21/00
Filed: 1978-03-01
Abstract: PURPOSE: To quickly open a pressure control valve and keep the quantity of steam constant, by comparing a signal of pressure of a turbine with that before an optional time and applying the pressure difference to the pressure control valve.  
     CONSTITUTION: If the flow rate of the steam through a bleeding line 4 has sharply decreased due to the fluctuation in the load on the turbine 2, the pressure signal of a pressure change detector 14 becomes much lower than that before a time t. Therefore, the variation in the pressure signal is large. When this variation exceeds a predetermined value set on a pressure variation change switch 15, the switch is actuated to apply an emergency opening signal to a switch circuit 16a of a solenoid valve 16. As a result, the solenoid valve 16 is opened and the variation in the pressure signal is applied to the pressure control valve 6 through an adder 17. Thus, the pressure control valve 6 is opened to a degree corresponding to the variation in the pressure signal to control the steam to constant pressure.

Abstract: PURPOSE: To ease correct strobe photographing by displaying the over- and under- light emission quantities.  
     CONSTITUTION: A decoder DE is connected via adder ADD 3 to two parallel adders ADD1, ADD2 and the LSI element 24 of the camera body is provided. The decoder DE is electrically connected to the light emission quantity display body 38 provided to a strobe device 33.

The distance numerical value information is doubled and is supplied together with the other information to the n-bit adder ADD3 where they are added. The results of the addition are converted to decimal information by the decoder DE and are then inputted to a guide number selection circuit 46. The under display part of the light emission quantity display body 38 is energized when the guide number information is larger than the maximum guide number of the strobe device 33 and the over display part when it is smaller.

Title: Manufacture of semiconductor laser
Inventor: OKABE NAOKO
IPC: H01S5/00
Filed: 1983-02-14
Abstract: PURPOSE:To prevent the damage of a cavity surface by reducing the growing speed for the film at the beginning of formation, in the process of forming a protection film to the cavity surface of the titled device. CONSTITUTION:When an alumina film 3 is formed by sputtering on the cavity surface 1 of the GaAs-GaAlAs laser 2, the growing speed for the film 3 is reduced by decreasing thrown power, in the beginning process before the film grows to several 100Angstrom , thus preventing the interface sag of the cavity surface 1. After the film 3 grows to several 100Angstrom , the growing speed for the film is increased by increasing the thrown power, thus shortening the time required to grow the film. Thereby, the heating of the element is restrained, and accordingly the decrease of lifetime is prevented.

Title: Rotary head type recording and reproducing device
Inventor: TAKIMOTO HIROYUKI
IPC: H04N5/783
Filed: 1983-02-14
Abstract: PURPOSE:To improve the interchangeability of the titled device with other devices by detecting and compensating the position shift of a head which is produced in a record mode due to the secular change, etc. of a mobile member to which the head is attached and therefore positioning the head at a proper prescribed position at all times. CONSTITUTION:A larger quantity of light is irradiated to a phototransistor TRQ2 when the height of head is larger than the proper value, and therefore the voltage V1 is smaller than the voltage V2. Then V0=R3(V1-V2)/R2+VCT is satisfied, and V0<VCT is obtained in the case of V1<V2. In other words, the control voltage lower than the proper value is applied to a driving circuit 21, and a bimorph plate is driven in the direction where the head height is reduced. While V1>V2 is satisfied when the head height is smaller than the prescribed value, and at the same time V0>VCT is satisfied. Thus the bimorph plate is driven in the direction where the head height is increased. Therefore it is possible to keep the head at a prescribed level of height by a control circuit even though the bimorph plate has a deformation due to the secular change, etc. as far as the head height is once controlled accurately to its original state.

Title: Seismoscope
Inventor: UBUKATA SUSUMU
IPC: G01H1/00

Abstract: PURPOSE:To enable a microcomputer to decide the distinction between an earth quake and a noise vibration by making the receiving dish part of a container for conductive liquid spherical and providing a radial electrode which is insulated electrically from the container outward from the center part. CONSTITUTION:The internal bottom surface 1A of the hermetically sealed container 1 which serves as a receiving disk for the conductive liquid 5 as an inertia element is made spherical and the electrode 4 is provided radially. The liquid 5 is therefore positioned in the center of the container 1 at a stationary attitude in a shape which is close to a sphere, but has a smaller vertical diameter than a horizontal diameter, and the liquid is separated from the electrode 4. Then when horizontal vibrations are applied, the liquid rolls on the receiving dish like a pendulum in the direction and the amplitude varies according to the value of the acceleration; when a reaction threshold value is exceeded, the liquid is brought into contact with an electrode 4 to output an ON-OFF signal. The electrode 4 is in the radial shape, so the liquid is impeded from detouring except in the vibration direction even in the case of contacting the electrode. Then the ON-OFF signal which is nearly equal to the period is generated to distinguish the disturbance vibration from a predetermined ON-OFF time.

Abstract: PURPOSE: To prevent clogging by communicating the inside of a screen portion with the outside of a bowl and providing the spiral route of a specific position with respect to the screen portion with slots. CONSTITUTION: The solids of a slurry supplied into the cylindrical portion of the solid portion 12 of the bowl are deposited toward the inside wall of the bowl by centrifugal force. A conveyor rotates relatively clockwise in an opposite direction with respect to the bowl and pushes and moves the deposited solids from the right to the left, moves the solids from the cylindrical portion of the solid portion 12 of the bowl into the tapered portion of the solid portion 12 and then, moves the solids into the screen portion 14 of the bowl and discharges the solids from a discharge opening 56. The excessive fluid effluents held in the solid portion 12 of the bowl are discharged through the opening 62. As a result, the wear, failure and clogging of the screen are eliminated.

Abstract: PURPOSE: To realize balance parallel operation by eliminating current unbalance by operating one power supply as a constant voltage power supply and the other as a constant-current power supply which supplies a current equal to that from the former or at a constant rate.  
     CONSTITUTION: Voltage supply E and current supply I are connected in parallel and the current value of this current supply I is equalized to that of a current flowing to voltage supply E. As a result, a voltage applied across load 10 is E and its current is 2I, so that the supply of a stabilized voltage will be done by two completely-balanced power units. In this constitution, since the parallel-connected power units are balanced substantially, even currents flow to both power units without being influenced by dissidence of characteristics constituting the power units even if it would occur, so that the reliability of the power unit can be improved.
