Title: Automated storage and retrieval system
Inventor: NAKAO TAKASHI
IPC: B66F17/00
Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To always hold a lift rail in a horizontal attitude by placing articles on a mobile body moving along the lift rail, driving a pair of hanging members and detecting the inclination of the lift rail in the height direction. SOLUTION: A lift rail 5 is provided with a mobile body 8 moving along the interior of the lift rail 5 in parallel. A control device controls the vertical motion of the lift rail 5, running of the mobile body 8 and placing of articles 41 by a robot hand 9. Generally, hanging members 6a and 6b are made to move at the same speed and moves the lift rail 5 in the vertical direction while holding the lift rail 5 horizontal by controlling servo motors 7a and 7b in synchronism with each other. Either the servo motor 7a or 7b is driven to minimize the difference between the elongation caused in the hanging member 6a or 6b based on the detection signals sent to the control device from sensors 13 and 14. For this reason, the inclination of the lift rail 5 in the height direction is corrected, making it possible to hold the lift rail 5 in a horizontal attitude.

IPC: H04N5/335
Filed: 1983-05-02
Abstract: PURPOSE:To obtain a clear picture by controlling brightness on a picture at each scanning line to a set reference brightness to decrease a contrast of an object to be pictured even if the contrast is very large through the control of the brightness at each scanning line. CONSTITUTION:When a value of a video signal is larger (too light) than a proper value for picture at a signal for the 1st scanning's share of the video signal, a peak value at one scanning's share is kept time by time and the holding peak value is reflected on the video signal of the next scanning's share by means of buffer function. That is, an applied voltage in response to a signal value of a buffer output is decided, and applied to an electronic shutter 8 in synchronizing with the leading point of a synchronizing signal (a). The luminous amount of transmitted light is decreased by the application to the electronic shutter 8. Since the delay in response exists in the electronic shutter 8, the change in the transmitted luminous amount attains to sawtooth wave. When the signal value for one scanning's share is over a set level (too dark), the transmitted luminous amount is increased by the similar operation.

Abstract: PURPOSE:To improve the life and reliability of an optical element by providing an insulating layer under an electrode which impresses a driving voltage thereby obviating generation of the breakdown of the electrode. CONSTITUTION:An insulating film 7 which flattens the shape of a ridge is formed on one surface of a substrate 4 after a ridge type waveguide 2 having the metallic electrode 1 is formed thereon. The tentire surface of the film 7 is thereafter uniformly etched and the film 7 on the ridge is thinner than the film 7 except on the ridge and therefor only the electrode 1 on the waveguide can be exposed. The layer 7 is formed under a bonding pad 6 when the pad 6 is formed by lift-off, etc. The easy formation of the layer 7 only under the pad 6 is thus made possible without using a mask.
