Title: Piezoelectric oscillator
Inventor: KOBAYASHI MASATOSHI
IPC: H03H3/02
Filed: 1979-10-25
Abstract: PURPOSE:To increase the working accuracy of a thin-gage piezoelectric oscillator and stabilize the frequency characteristics, by applying the ion impact method. CONSTITUTION:The mask 11 is applied to the piezoelectric crystal plate 12, and this plate is stored into the vaccum room 13. Then the Ar gas 15 is introduced to secure ionization by the ion source 14, thus obtaining the uniform beam 17. And then an impact is given to the plate 12 to carry out blanking process. The mask material is selected properly according to the material or the thickness of the crystal plate. With a vertical incidence of the beam 17, a straight cross section is obtained. Furthermore, no cracking is caused since the breaking work is carried out at the level of molecule. Accordingly, the stability of frequency is enhanced greatly owing to the uneven form of the cross section, at the same time simplifying the manufacturing process.

Title: Lens device having electromagnetically driven diaphragm
Inventor: ICHIYANAGI TOSHIICHI
IPC: G03B7/10
Filed: 1981-09-02
Abstract: PURPOSE:To eliminate the clatters between a stopper and a gear and to decrease the errors in an aperture value by passing electric current in an opposite direction to a diaphragm meter while the diaphragm is held stopper by electromagnetic driving.

Title: Monitoring circuit for semiconductor laser driving current
Inventor: KONO TOSHIBUMI
IPC: H04B10/293
Filed: 1985-06-25
Abstract: PURPOSE:To precisely monitor a current flowing actually without affecting the waveform of the flowing current at all, by using a monitoring circuit having substantially the same construction as a semiconductor laser driving circuit excepting that no current flowing to a semiconductor laser is made to branch off. CONSTITUTION:A monitoring circuit for a driving current constitutes a simulative semiconductor laser driving circuit which has substantially the same construction as a semiconductor laser driving circuit excepting that the respective collectors of transistors 2' and 3' are grounded directly without interposition of a semiconductor laser 1, in other words, no current flowing to the semiconductor laser 1 is made to branch. With respect to a transistor 2 for driving the semiconductor laser and the transistor 2' for monitoring a peak value of the driving current, the respective base- collector voltage differs only by a slight voltage drop occurring in the semiconductor laser 1, while the respective base-emitter voltage determining a current flowing there- through is the same. Accordingly, a voltage drop occurring in a resistor 4' is proportional exactly to an actual driving current flowing through the transistor 2 for driving the semiconductor laser.

Title: Feed water flow and feed water pressure control device at transformer operation plant
Inventor: KAMATAKI YOSHIHISA
IPC: F04B49/00
Filed: 1977-11-17
Abstract: PURPOSE: To obtain proper feed water flow and pressure by keeping the turbine at the rotational frequence of more than primary critical speed, and by controlling constant the feed water pressure by regulating valve.  
     CONSTITUTION: The device is equipped with feed water pressure regulating valve 6 and turbine adjusting valve 8.

With the turbine 4 kept at the rotational frequency of more than the primary critical speed, a constant control of feed water pressure of the adjusting valve 6 is achieved against the feed water pressure variation based on the rotational frequency control of the turbine 4, and the appropriate feed water flow and pressure can be provided to the boiler without operating the turbine 4 for a long time in the primary criltirical speed range at the time of low load.

Title: Switching power circuit
Inventor: TAKAMURA AKISUKE
IPC: H02M3/28
Filed: 1989-05-31
Abstract: PURPOSE:To prevent a voltage drop due to an overcurrent or the puncture of a switching element by suppressing a continuous pulse narrowly, when the pulse output of a pulse-width control circuit outputs the continuous pulse by malfunction. CONSTITUTION:When a malfunction inside a pulse-width control circuit 6 causes first output pulse signal lines 31 to output a pulse continuously with a timing required for outputting a second output pulse, the output of an integration circuit 15 cannot be reset by second output pulse signal lines 32. Beyond to potential of a reference power supply 16, therefore, the output of a comparing circuit output part 17 changes to a LOW level one, and when the output and AND of an inverter 9 are taken, the continuous pulse of the output of a two- input AND circuit 11 is suppressed narrowly. Thus, it is possible to prevent not only the saturation of a main transformer in a main switching circuit 5 but also the decrease in power due to an overcurrent or the puncture of a switching element.

IPC: G01S13/60
Filed: 1992-05-29
Abstract: PURPOSE:To restrain clutter caused by ocean current speed, and detect a very slowly moving target on the sea level by correcting a received signal according to averaged ocean current speed. CONSTITUTION:A signal from an oscillation correcting circuit 33 is delayed until a next reflection signal is received by means of a pulse repetition interval PRI delay circuit 34. When the next reflection signal is outputted from the circuit 33, the circuit 34 outputs a previous received signal, and inputs it to an ocean current speed detecting circuit 35 in the same timing. The circuit 35 detects a phase difference between the received signals corresponding to respective previous and next transmission pulses, that is, a phase rotational quantity of Doppler frequency caused by an ocean current. An ocean current speed averaging circuit 36 averages the number of optional range cells and a phase rotational quantity of the number of pulses, and reduces detection errors. When the first received signal is outputted from a sweep memory circuit 38 after output of the circuit 36 is set in an ocean current speed correcting circuit 37 while using it as ocean current speed on the sea level, ocean current speed correction is carried out on this signal by means of the circuit 37, and it is transmitted to an MTI circuit 39, and a clutter component can be eliminated sufficiently.
