Title: Inspection method for leak of stopper-executed state
Inventor: ATSUMI HISAO
IPC: G01M3/36
Filed: 1996-02-05
Abstract: PROBLEM TO BE SOLVED: To obtain an inspection method in which an inspection can be performed precisely by a method wherein the height of the ceiling face of a stopper at an airtight container which is conveyed continuously is measured from the upstream part to the downstream part of its conveyance direction, its data is computed to obtain a function approximation and the unevenness of the ceiling face of the stopper is discriminated on the basis of its curve. SOLUTION: A stopper 4 which is executed to an airtight container 3 to be conveyed continuously is irradiated with a laser beam LS by a laser beam-type distance sensor 3, and its height is measured. The time in which the edge part on the upstream side and the edge part on the downstream side of the ceiling face 4 of the stopper are passed through the irradiation position of the sensor 3 is detected by another sensor arranged near a conveyance passage, and the measurement of the height is started or finished in synchronization with the time. Height measured data is sent to a data processor 5, and the function of a curve of secondary degree which envelops the data is found by a program. The unevenness of the state of the stopper 4 is judged by whether the sign of a term x<2> in the approximated function is positive or negative.  That is to say, when the sign of the term x<2> is negative, the curve is convex, and the ceiling face is convex so as to be discriminated to be nondefective. When the sign is positive or 0, the ceiling face is judged to be defective, and a cylinder for exclusion is driven by a sequence controller 6.

Inventor: OUCHIDA YASUSHI
IPC: F21V8/00
Filed: 1999-01-27
Abstract: PROBLEM TO BE SOLVED: To obtain a liquid crystal display device including an illuminating device which can control the chromaticity. SOLUTION: In this device, a movable reflection plate 5 can be disposed between a cold cathode tube as a light source 4 disposed in adjacent to a light guiding body 1 and a reflection plate 3 which surrounds the light source 4 with the side face of the light guiding body l.

Therefore, two kinds of illumination states can be obtd., namely, the light emitted from the light source 4 is reflected by the movable reflection plate 5 to the direction to the light transmission body 1 or the light is reflected by the reflection plate 3. Thus, chromaticity of the illumination face of the light guiding body 1 can be controlled.

IPC: B21B37/18
Filed: 1978-02-22
Abstract: PURPOSE:To carry out very high accurate control for the eccentricity of rolls, by memorizing the waveform of the eccentricity of each backup roll after removing the noise, and by reading out the memory correspondingly to the position of revolution of the roll when the rolling is carried out. CONSTITUTION:The diameter ratio R of upper and lower backup rolls 2a, 2b, is computed from the pulse inputted to the digital computer 10 from the pulse generators 5a, 5b. Next, the signal from the load cell 4 for N revolutions is added to every position of revolution of rolls 2a, 2b. N = (K/11.0 - R1) - n, in which n is the difference between the value of K/11.0 - R1 and an integer nearest to this value, and K is the number of times of reapearance of the relation of relative position between upper and lower backup rolls. Then, the control on the eccentricity is carried out using the memorized waveform of eccentricity of the roll. Through this process, the computer 10 learns the positions of revolution and speeds of rolls 2a, 2b, adds to them the value corresponding to the lag of response, delivers a signal, and actuates the screw down cylinder 6.
