Title: Speaker equipment
Inventor: MAEDA KEIJIRO
IPC: H04R19/02
Filed: 1993-08-17
Abstract: PURPOSE:To improve efficiency of a static speaker by arranging plural fixed electrode plates on both sides of a moving electrode and driving the speaker so that an electric field generated between the fixed electrodes is larger at an circumferential side than that of the inner circumferential side, thereby vibrating the moving electrode in a form close to a flat plate. CONSTITUTION:One side of rectangular frame electrode plates 24A-24D is supported in the middle of a rectangular opening of a holder in an element 20 of a speaker equipment 30 and other plate electrodes are arranged by insulating and separating with a prescribed spacing so as to surround sequentially them and fixed to a frame. In a manner that on electrode arranged far from the outside of the electrodes 24, 26 formed in this way becomes higher voltages in turn, a driving signal is impressed by providing secondary taps of a booster transformer. Thus, even when both ends of a diaphragm 12 are supported and bound, the diaphragm 12 is vibrated in a form close to a flat plate. Thus, a large sound pressure is obtained efficiently without spreading the interval of the fixed electrodes.

Title: Motor operated valve
Inventor: TAKANAKA MASAHIDE
IPC: F16K31/04
Filed: 1987-09-09
Abstract: PURPOSE:To secure the durability of a brake face and reduce power consumption by braking the rotary shaft of a motor used in a motor valve employing face contact by a magnetic brake operated on excitation, and connecting the motor and the brake to a power supply alternatively. CONSTITUTION:The rotational speed of a motor 1 is reduced via an intermediate reduction shaft 16, 17 and gears 13, 14, 15, and its torque is increased to be transmitted to a valve rod 11 to cause a valve body 13 to open. In this case, while electric current to the motor 1 is intercepted by a valve opening switch 5, power supply is changed over to the side of a magnetic brake 4. Hence a valve body 10 will hold a full opening condition by holding force due to the face contact of the magnetic valve 4 and a spring 7 attached to the intermediate reduction shaft 16, in the state of complete winding, is provided with a force in the direction of valve closing. Additionally, in power failure, current to the magnetic brake 4 is intercepted to cause the valve body 10 to close due to spring force.

Title: Radio controller of video tape recorder
Inventor: SAKAI TAKEOKI
IPC: G11B15/02
Filed: 1984-10-25
Abstract: PURPOSE:To obtain a start-stop signal of a VTR from a video signal separated from an RF signal by discriminating the presence or absence of a video signal separated from a received signal and producing the start-stop signal of the VTR through a discriminating circuit. CONSTITUTION:A converted DC signal is compared with the zero potential by a comparator 4. Thus the output of the comparator 4 is set at 'L'. When the transmission of the RF signal from the transmission side is stopped, the output of a rectifying/smoothing circuit 3 is set approximately at zero potential. Then the output of the comparator 4 is changed to 'H' from 'L', and a potential of 'H' is divided by resistances R5 and R6 and fed positive back to the positive input of an operational amplifier U. Therefore the output of the comparator 4 is never inverted unless the output of the circuit 3 exceeds said divided potential. Then the transmission of the RF signal is restarted from the transmission side, the output of the circuit 3 exceeds the hysteresis level of the circuit 4 and changed again to 'L'. Then the output of the comparator 4 delivers a DC voltage signal which is set at 'L' only when the video signal is transmitted.

Title: Temperature compensation of piezoelectric actuator
Inventor: MAKINO SHINGO
IPC: H01L41/04
Filed: 1986-09-22
Abstract: PURPOSE:To reduce the change in height of the head of a piezoelectric actuator with respect to temperature, by converting the electrostatic capacitances of a plurality of laminated piezoelectric elements having the same structure into voltages, and changing DC bias voltages, which are applied to the other piezoelectric elements with said voltages. CONSTITUTION:Electrostatic capacitances between electrodes of piezoelectric elements 1 are changed with ambient temperature. The oscillating frequency of each oscillating circuit 2 is determined by capacitance between electrodes of the piezoelectric element 1. The output of the oscillating circuit 2 is applied to a frequency-voltage conversion circuit 3. Its output is adjusted to an adequate correcting amount, and the result is applied to an adding circuit 5. A driving signal for a piezoelectric actuator is applied to the other input of the adding circuit 5. The output of the adding circuit 5 becomes a signal, which is obtained by changing the DC bias voltage of the driving signal for the piezoelectric actuator at an input terminal 4 by the temperature. The output of the adding circuit 5 is amplified to the voltage required for driving a piezoelectric actuator 7 by a driving circuit 6. Therefore the position of the height of the head of the piezoelectric actuator is not changed even if the ambient temperature is changed.

Abstract: PURPOSE:To prevent air bite and minimize the water supply quantity to a water tank by installing a delay device which delays by a specified time from the start of ice making process the operation of a circulation pump which circulates water in the water tank through each ice making chamber during ice making process. CONSTITUTION:An attempt is made to install a circulation pump 9 which circulates water in a water tank 6 through each ice making chamber during ice making process. When a water pan has finished double acting and an ice making process starts simultaneously, water is sprayed over the surface of the water pan and water supply to the water 6 is arranged to start. When the water is supplied to a specified water level in the water tank, water spray is halted. Then, an attempt is made to install a delay device which delays the operation of the circulation pump 9 by a specified time from the start of ice making process. When water is supplied to the specified water level in the water tank 6, after starting the ice making process in this manner, the operation of the circulation pump 9 is adapted to start. This construction makes it possible to prevent the circulation pump from air bite and maintain a required quantity of water since the circulation pump 9 starts its operation before the specified water level in the water tank is detected.

Title: Charger
Inventor: TODA MANABU
IPC: H02J7/04
Filed: 1990-08-27
Abstract: PURPOSE:To suppress capacity drop of a battery, to lengthen the service life of battery and to lengthen the operating time of an electronic appliance incorporating a battery by once discharging a chargeable battery and then charging the battery. CONSTITUTION:When a start switch 21 is closed, input at the clock terminal CR of a flip-flop 31 has an L level. Consequently, transistors 32, 33 are turned ON by an output signal at terminal Q to conduct a relay coil 61 thus switching a movable contact X to the side of a fixed contact Z. Since a closed circuit is established by a secondary battery 8 and a resistor 51, voltage of the secondary battery 8 drops through discharge. Consequently, positive side input of a comparator 43 drops and when it drops below a reference voltage VL, output of the comparator 43 is inverted to L level. The flip-flop 31 is thereby reset to turn the transistors 32, 33 OFF thus interrupting power supply to the relay coil 61. The secondary battery 8 is fed with charging current from a rectifying circuit 72 and charged.
