Title: Method and device for operating automatic antenna expanding and contracting control using motor
Inventor: SUGA MITSUHIRO
IPC: H01Q1/10
Filed: 1982-03-03
Abstract: PURPOSE:To ensure a proper expanding/contracting operation of an antenna with a clutch mechanism without producing noises, by setting a clutch torque which is slightly larger than the expanding/contracting torque of a normal antenna. CONSTITUTION:A press contacting torque between a clutch plate 3 and a drum 2, i.e. the sum of press-contacting friction torques based on a spring 6 between an engaging projected part 37 and the rear surface of the drum 2 as well as between an engaging projected part 27 and the rear surface of the clutch plate 3, is set slightly larger than the expanding/contracting torque of a normal antenna at a time point when a switch is turned off. The antenna can be expanded completely and contracted owing to the rotational inertia of a motor 10, the drum 2 and a worm wheel 1 respectively even though the conduction of electricity is turned off to the motor 10.

Title: Surface potential sensor
Inventor: SUZUKI KOUJI
IPC: G03G21/00
Filed: 1981-03-09
Abstract: PURPOSE:To eliminate the influence of gain fluctuation and drift accompanied with the environmental change of a processing circuit, by using a piezoelectric element as a chopper driving means and feeding back the output of a sensor to shield member and a chopper part. CONSTITUTION:A measuring window 21 is opened and closed at a constant period by the oscillation of a piezoelectric tuning fork 12 where piezoelectric elements 13 and 13b are attached to the side part, and chopper electrodes 14 interlink to break the line of electric force based on the electric charge of a face to be measured, thereby inducing an AC voltage having an amplitude proportional to the differential potential between a potential to be measured and  the chopper potential on the electrode surface of a measuring electrode 17. This  induced signal is amplified by preamplifiers 29 and 30 and is subjected to the  DC regenerative amplification and is fed back to the chopper electrode 14 and a  shield cover 20 to keep the chopper potential and the shield potential in the  same value as the potential to be measured. Thus, the voltage fed back to the  chopper is the voltage to be measured itself which is fluctuated by a measure distance, and a high-precision measurement is possible.

Title: Cooling equipment for motor
Inventor: NAKAMURA KATSUHIKO
IPC: H02K9/08
Filed: 1991-02-27
Abstract: PURPOSE:To obtain heat transfer performance by filling up a gap formed between the mold material of a stator coil and the inner peripheral surface of a housing with a gas having a high thermal conductivity without filling up the gap between the housing and the stator coil with a resin. CONSTITUTION:A housing 1 has a sealed construction, and helium gas having a high thermal conductivity is filled inside the housing, and thus the helium gas is present in a gap 20 between the mold material 19 of a coil 16 and the inner face of the first and second housings 2 and 4. Since this helium gas has a high thermal conductivity, the passing rate of heat (amount of heat passed per unit area) from the mold material 19 to the housing 1 becomes high. Thus, even in the case of frameless motor, no filling of a resin between the housing 1 and the stator coil 16 is required, and almost the same heat transfer performance can be obtained and the cooling performance of the motor is improved.

Abstract: PURPOSE:To detect a fingerprint image having no distortion by a wide range of a fingertip, by forming concentrically an input surface of uneven information of a light leading body, and the outside peripheral surface of the light leading body. CONSTITUTION:An uneven surface information input surface 20 of a light leading body 15 and its outside peripheral surface 21 are formed concentrically centering around a shaft center 16. When a fingertip 10 is placed on this input surface 20, a cylindrical lens 22 rotates and a light beam is irradiated, and a light beam exceeding a critical angle, among the light beams which have been scattered by a projecting part 6 of a fingerprint is made incident on a hologram 3. Subsequently, the light beam which has been diffracted by the hologram 3 is detected in a shape of a line by a line sensor 23. In that case, since the input surface 2 and the outside peripheral surface 21 form a concentric circle, the wall thickness becomes equal, and an optical path length to the hologram 3 becomes constant, therefore, an image having no distortion is obtained. Also, since the input surface is a concave curved surface, information can be inputted by a wide range of the fingertip.
