Filed: 1993-06-11
Abstract: PURPOSE:To extend an available image pickup illuminance range by varying a correction characteristic of a gamma correction circuit into an optimum correction characteristic in response to an image pickup light quantity with a characteristic control signal of the correction characteristic control section based on a current image pickup illuminance discriminated by an image pickup light quantity and a shutter speed. CONSTITUTION:A control section 24 identifies a current image pickup light quantity and a current shutter speed for each field based on a discrimination result of a discrimination section 17 and a shutter speed by a decoder 23 to generate a correction control signal SW for a correction characteristic. The signal SW is fed to a selection section 10 of a correction circuit 6 and the selection section 10 selects alternatively an output of correction sections 7-9 according to the signal SW. The correction sections 7-9 are set respectively to the gamma correction characteristic corresponding to that at a low illuminance, a high illuminance and a standard illuminance. Then the optimum correction characteristic of the circuit 6 is set as shown in figure (a) to prevent black level distortion at discrimination of the low illuminance to generate the signal SW for the correction section 7. Moreover, the optimum correction characteristic of the circuit 6 is set as shown in figure (b) to prevent white level distortion at discrimination of the high illuminance to generate the signal SW for the correction section 8.

Abstract: PURPOSE:To shorten substantially a period of time of the termination of vibration and enable a stable high-speed positioning by enclosing a viscous fluid in an enclosure inner part where a rotor is provided. CONSTITUTION:A rotor 3 rotates in steps at a fixed angle theta when exciting phases of a winding 2 wound around a stator 1 are changed from one to another successively. Silicone oil 7 as a viscous fluid is filled in an enclosure 6 for surrounding a rotor 3 and a stator 1. Therefore, the rotor 3 meets with a damping resistance determined by a product of a viscosity of silicone oil 7 and an angular velocity of rotor 3 when said rotor is stopped. Consequently, the vibration of the rotor 3 is damped abruptly and exponentially, and a period of time to the termination of the vibration is shortened substantially so that a stable high-speed positioning becomes possible.

Abstract: PURPOSE:To thin the thickness of a fan, and to improve the efficiency of a blast by journaling a rotor taking a blade shape to an outer frame incorporating a stator and a coil. CONSTITUTION:Stators and coils 2 are incorporated at the four corners of an outer frame 1.

Abstract: PURPOSE:To suppress the increase in the number of wires and circuit scale even with multi-stage of pseuso random signal (PN) generating circuits by providing an NOR circuit and an integration circuit inputting two inputs to an EX-OR circuit constituting the PN signal generation circuits. CONSTITUTION:An output of SR(shift registers) 1-3 is all 0, an output of an NOR circuit 11 goes to 1 and a potential at a point (f) of an inegration circuit 12 is risen according to the time constant as shown in Fig. When the potential at the point (f) is higher than the reference potential of an OR circuit 10, a point (a) goes to 1 level as shown in A and a potential of a point (b) goes to 1 level as shown in B. When an output of any one of the SRs goes to 1, the circuit starts generation of a PN signal and when the level at a point (c) goes to 1, an output of an NOR circuit 11 goes to 0, a potential at the point (f) is changed rapidly to 0 by the operation of a diode D as shown in (f) and no effect is given to the generation of signal. In this case, even if the SR is constituted in multi- stage, input lines to the NOR circuit 11 will do with two input lines to the EX-OR circuit 6. Further, the wires through the NOR circuit, integrating circuit and the diode are as shown in Fig.
