Title: Image pickup device
Inventor: KITAZAWA TOMOFUMI
IPC: H04N5/225
Filed: 1999-11-02
Abstract: PROBLEM TO BE SOLVED: To shift pixels and to remove the high-frequency components of a subject image while preventing an image pickup device, which can have its photography mode switched between normal photography by pixel shifting and normal photography where the pixel shifting is not used, from increasing in cost and becoming large-sized. SOLUTION: In normal photographing, an electronic shutter can remove a high-frequency component of spatial frequency of a subject by moving incident light to an image pickup plane between the start of accumulation of electric charges and shutter-off operation. In photographing where pixels are shifted, the incidence position of the incident light is shifted to the image pickup plane between the end of starting exposure and the start of next exposure. An actuator, which switches the optical path for pixel shifting and a means which relatively moves the incident light in the exposure for prevention against the generation of a false signal in normal photography are used partially or wholly, in common.

Abstract: PURPOSE:To prevent the formation of a concentration boundary film and improve permeation efficiency of a selected solution component by making a selective permeation separation membrane by a wavy shape in a liquid separation system by a penetration gasification method using the permselective membrane. CONSTITUTION:Permselective membranes 7, 7' are made to be a wavy shape in a liquid separation apparatus composed of a high pressure side first chamber 1 to which a prescribed liquid mixture of a liquid to be selected and another liquid containing the liquid to be selected is supplied and a low pressure side second chamber 2 adjacent to the high pressure side first chamber 1 having the permselective membranes 7, 7' for penetration gas pressure between them. Since the liquid mixture supplied to the inside 11 of the high pressure side first chamber flows curvedly along the wavy planes of the permselective membranes 7, 7', a concentration boundary film on the surfaces of the selective permeation membrane 7, 7' is disturbed and the concentration boundary film is not formed. Also, owing to the wavy shapes of the permselective membrane 7, 7', the surface area (permeation surface area) of the membranes 7, 7' are enlarged and in this point, the permeation efficiency is improved.

Filed: 1998-11-04
Abstract: PROBLEM TO BE SOLVED: To provide a solenoid valve furnished with a valve element which can be grinding processed highly accurately and efficiently, by various sorts of grinding process methods such as a centerless process. SOLUTION: Grooves 98e for pressure removing formed at the outer peripheries 98d of a stem 98a are made in a spiral form.

As for modulation frequency f1 and f2, the value of DELTAf is set higher than the cutoff frequency (fc) of the low pass filter 70, and the sampling frequency (fs) is set lower than the cutoff frequency (fc). Thus, the image of the dark visual field is displayed on a CRT display device 73.
