Title: Transducer for atmospheric ultrasonic wave
Inventor: MAKINO SHIRO
IPC: H04R17/00
Filed: 1988-11-08
Abstract: PURPOSE:To improve the reliability and deterioration in the characteristic with respect to ambient temperature by containing a vibrator in a case, providing a sound matching layer to an ultrasonic wave radiation face of the vibrator and forming the acoustic matching layer by a foamed inorganic material. CONSTITUTION:A vibrator 2 is contained in a case 4 and an acoustic matching layer 3 is provided to an ultrasonic wave radiation face of the vibrator 2. Then the acoustic matching layer 3 is made of a foamed inorganic material. As the foamed inorganic material, an inorganic material has air bubbles and is low in the density, then the acoustic impedance is low and then the material acts like the acoustic matching layer 3. Thus, the acoustic matching layer 3 is not softened even at a high temperature environment in excess of the temperature range used normally and the thermal expansion coefficient is small and close to the thermal expansion coefficient of a piezoelectric ceramic used for the vibrator, then the distortion exerted to the bonding face with the vibrator is reduced.

Title: Pressure type pouring furnace
Inventor: HAYASHI SHIZUO
IPC: B22D18/06
Filed: 1984-12-25
Abstract: PURPOSE:To increase response speed and to attain exact pressure control in a furnace which pressurizes the air in a storage chamber on the basis of the amt. of the molten metal in the furnace to lift and discharge the molten metal by operating a pressure controller by the detected air pressure in the storage chamber and controlling pressurization and evacuation control valves. CONSTITUTION:The amt. of the molten metal in the furnace is detected by a load cell 12. A pressurization solenoid valve 16 and an evacuation solenoid valve 17 are operated by a CPU device 20 to pressurize the air in the storage chamber 2 by which the molten metal is lifted and discharged 8. The signal for the detected air pressure 10 of the chamber 2 is fed to a pressure controller 11 which compares said signal with the control signal from the CPU20 and feeds the control signal to the pressurization control valve 13 and the evacuation control valve 14 thereby controlling exactly the pressurizing force. The response speed is made faster than heretofore and the malfunction owing to noise, etc. is eliminated. The pressure control is thus made exact and sure.

Title: Controller for synchronous motor
Inventor: NAKAJIMA KIHEI
IPC: H02P27/06
Filed: 1986-11-28
Abstract: PURPOSE:To stably operate a synchronous motor in a wide operating range by setting a delay reactive current to the motor according to the speed and the magnitude of a load, and regulating the voltage of the motor by the comparison of the value with the detected value. CONSTITUTION:A reactive current calculator 10 calculates and outputs a reactive current ld from a phase angle theta, u-phase and w-phase current detected values from a current detector 9. The obtained value Id is subtracted from a reactive current command value I'd, amplified by an amplifier 12, added by an adder 14 to a value proportional to an angular frequency omega to obtain a voltage of the amplitude V. Thus, the voltage can be automatically regulated according to the magnitude of the load to always stably operate a synchronous motor.

Title: Light interference angular velocity meter
Inventor: ONO ARITAKA
IPC: G01C19/72
Filed: 1992-10-21
Abstract: PURPOSE:To always accurately detect the phase difference between both right and left light beams by increasing the amplifier gain of a gain control driver when the increase of luminus energy of emitted light beams over a limit value is required at the basic value of the amplifier gain to keep constant the output of a detector device for overall gain. CONSTITUTION:A comparator 19 compares the output VPD of a current-voltage converter 13 with a reference voltage (a basic value) VO to output a selection signal S2 to a selector device 18, and a difference detector 20 and a filter device 21, for example, a PID filter or the like operates so that a signal VG obtained after the signal from a gain control driver 7 is amplified and attenuated by an amplification and attenuation device 22 becomes equal to the basic value VO to keep constant the amplification factor of the amplifier 7 at the basic amplification factor in the case of VPD<VO. When the overall loss of a system increases and cannot be coped with only by controlling the luminus energy of emitted light, the output of the selector device 18 becomes equal to the output V2W of a detector device for overall gain. Then, the detector device 20 and the filter device 21 operate so as to satisfy the relation of V2W=VO, so that the amplification factor of the amplifier 7 is controlled to reduce the overall loss of the system, thereby performing the variable control of the luminus energy of the emitted light. Further, when the overall loss is reduced, the amplification factor is kept constant at the basic amplification factor.
