Title: Rotary compressor
Inventor: IN EI
IPC: F04C23/00
Filed: 1992-09-30
Abstract: PURPOSE: To guarantee silent and balanced rotation of a main shaft and reduce magnetic attraction, gap higher harmonies and vibrational noise in a motor. CONSTITUTION: A rotary compressor comprises a motor, a main shaft 5 connected rotatably by the motor, and four cylinders 30 arranged in the same plane. Each of the cylinders comprises a roller 6 eccentrically mounted to a roller shaft, and a vane 32 slidably disposed in a body of the cylinder and always being in contact with the roller. The roller shaft is connected to the main shaft via a gear, and the roller shaft rotates simultaneously when the main shaft is rotated. A compression chamber 31 of the cylinder is divided by the vane into a suction area 31A of the compression chamber and a discharge area 31B of the compression chamber. The compression chamber is arranged symmetrically about the main shaft so as to compensate for a vibration force generated by other cylinders, thus permitting silent and balanced rotation of the rotary compressor.

Title: Image pickup device and flicker correcting circuit
Inventor: OKAWA ATSUSHI
IPC: H04N5/243
Filed: 1999-09-16
Abstract: PROBLEM TO BE SOLVED: To reduce flicker noises without a malfunction even in the case of an object luminance change while securing an S/N at the time of video photographing under the AC power source illumination of 50 Hz. SOLUTION: Flicker is corrected by adding a flicker correction quantity to a shutter speed based on a difference between a light average value for three fields and the lightness of a present field. Besides, when the minimum value of the flicker correction quantities for three fields and a shutter speed under exposure control are added and the result is equal to or lower than a minimum shutter speed, an offset quantity calculated so as to provide the minimum shutter speed is added to the flicker correction quantity and defined as the flicker correction quantity of the present field. The lowest shutter speed can be 1/60 sec and the S/N at the time of low luminosity can be secured.  Further, the flicker correction quantity of the present field is provided by adding an increase/decrease quantity to the flicker correction quantity before three fields and the limit value of the flicker correction quantity is varied corresponding to the shutter speed under exposure control. Thus, the malfunction caused by the luminance change can be prevented.
