Title: Aperture compensation method for image pickup device
Inventor: IIZUKA HIROSHI
IPC: H04N5/208
Filed: 1988-11-19
Abstract: PURPOSE:To improve the photoelectric conversion characteristic with high accuracy by providing a preamplifier, a clamp circuit and a frequency correction circuit or the like, correcting phase distortion depending on the distortion of the current density distribution of the scanning beam, and applying aperture compensation. CONSTITUTION:An output signal (picture signal) of a photoconductive image pickup tube 1 based on beam scanning is amplified by a broad band preamplifier 2 without changing its characteristic, subject to DC clamp by a clamp circuit 3 and the result is inputted to a correction circuit 4. In this case, the response characteristic of the output signal of the tube 1 via the circuit 3 is made asynchronous depending on the asymmetry based on the self-sharpening effect of the current density distribution of the scanning beam or the like. Thus, the frequency characteristic of the input signal of the circuit 4 is deteriorated depending on the beam diameter of the scanning beam and the phase characteristic is distorted depending on the self-sharpening effect of the scanning beam or the like, but the circuit 4 applies the linear processing of the phase characteristic and the frequency correction. Thus, the output signal of the tube 1 is subject to aperture compensation, the photoelectric conversion characteristic is improved and high accuracy is attained.

Title: Operation control method of washing machine
Inventor: YAMAGAMI KAZUHIKO
IPC: D06F33/02
Filed: 1998-10-16
Abstract: PROBLEM TO BE SOLVED: To enable a user to set the applying voltage at a suitable value against a load in a short time to reduce the consumed quantity of electricity by judging the input load of washing before starting agitating operation to start washing in an energizing condition corresponding to the judged input load and changing to the optimum energizing condition. SOLUTION: Before starting a washing process by rotation of agitating blade, the input load of washing is judged for determining the water level and energizing ON/OFF times to a motor. The optimum voltage value corresponding to the judged load is calculated and applied to a motor to start the agitating motion. Since the judged load does not necessarily match the load during agitating operation, the optimum energizing voltage is corrected to the quantity of load in the agitating operation. That is, the number of rotations from starting agitating operation until the agitation blade reversely rotates once is detected and the number of rotations is compared with the target setting number of rotations. When the detected number of rotations is higher than the target set value, the engaging voltage of the motor is lowered and, when lower, the voltage is raised.
