IPC: H04N5/232
Filed: 1991-08-09
Abstract: PURPOSE:To accurately and easily enable an automatic focussing. CONSTITUTION:When an actuator 108 moves a focus lens 101 in an arbitrary direction under the control of an operation control part 305a, an image pickup surface 106 converts a video signal which passes through an optical system and is made incident on the surface into an electric signal and outputs it as focus voltage to a system controller 300a via a high-pass filter 118. The operation control part 305a consecutively inputs the last twenty consecutive absolute values of the focus voltage to a focus voltage absolute value memory 301 via the high-pass filter 118, detects the voltage difference obtained by taking the difference of adjacent data of the absolute values of the stored focus voltage and stores the obtained voltage difference in a focus voltage difference memory 302. The control part 305a predicts a focus point based on the history of the focus voltage absolute values and the voltage difference, controls the actuator 108 to make automatic focussing, and changes the method of focussing until the focus voltage is stabilized when the focus voltage is suddenly changed due to noise or sudden change of the object.

Title: Air-conditioning machine
Inventor: KOSOTO SOICHI
IPC: B01D46/10
Filed: 1987-09-11
Abstract: PURPOSE:To secure the rate of air, passing through a heat exchanging unit, by a method wherein another suction port is opened when the increase of the ventilating resistance of a normal suction port has been detected, upon the operation of an air-conditioning machine, mounting an air filter having a high dust-proofing efficiency. CONSTITUTION:An air-conditioning machine is operated usually while sucking air from a suction port 5a. When an air filter 6, a charged filter 8 or the like is clogged and the ventilating resistance thereof is increased, the temperature rise of a heat exchanger 3 is detected by a temperature sensor 10, provided in the heat exchanger 3. When the ventilating resistance is increased and the rate of air passing through the heat exchanger 3 is decreased, the temperature of the heat exchanger 3 rises in the case of heating operation while the temperature of the heat exchanger 3 falls in the case of cooling operation. Then, the change of the temperature is detected by the sensor 10 and is compared with a reference value to command the operation of a means for opening another suction port 5c from a control unit. According to this operation, a motor 9 is driven to open a shutter 5d and suck air through the suction port 50 whereby the performance of the air-conditioning machine may be secured.

Title: Motor
Inventor: IMAMURA TAKAHIRO
IPC: H02K29/03
Filed: 1990-08-30
Abstract: PURPOSE:To increase a no load revolution and a starting torque by a method wherein DC currents or low frequency currents are applied to coils at the time of start and, after the start, high frequency currents are applied to the coils to drive a motor. CONSTITUTION:At the time of start, as driving currents outputted from respective amplifiers 31, 32 and 33 are currents which are modulated by PWM with a carrier frequency as low as several tens - several hundreds of Hertz, the impedances of respective capacitors 71, 72 and 73 are sufficiently higher than the impedance of auxiliary coils 61, 62 and 63 and hence the driving currents are applied to main coils 51, 52 and 53 and the corresponding auxiliary coils 61, 62 and 63 respectively in series. In this state, a torque constant is large and a large starting torque is generated. Then, when a revolution reaches a certain value after the start, the oscillation frequency of an oscillator 8 is increased to several kilo Herz to several tens of kilo Hertz. In this state, the currents applied to the coils 51, 52 and 53 are bypassed by the capacitors 71, 72 and 73. As a result, an apparent torque constant is reduced and a no load revolution can be increased.
