Inventor: FUJII KEIZO
IPC: G02F1/1337
Filed: 1996-10-23
Abstract: PROBLEM TO BE SOLVED: To apply uniform rubbing to a thin film by preventing fluctuations of the frictional stress. SOLUTION: On the surface of one side of the rectangular substrate 2 of an original substrate 1, a thin film 5 which covers at least display areas for display 4 exept external connection terminals 3 and consisting of oriented film material is formed so that sides 2a∼2d of the substrate 2 and sides 5a∼5d of the thin film 5 become respectively parallel. A rubbing roller 6 is selected so that the angle θ formed by the side 2c of the substrate 2 and the moving direction 7 of the roller becomes in the range from 75 degrees to 90 degrees and applies rubbing processings to the thin film 5 while rotating in the direction 7.  As a result, since the length of a contact side 7a between the original substrate 1 and the rubbing roller 6 is kept roughly constant, fluctuations of frictional stress to be caused by the contact between the original substrate 1 and the rubbing roller 6 in the rubbing processings are prevented thereby applying orientation processings uniformly and oriented states of liquid crystal molecules at the time the original substrate 1 is made to be a liquid crystal display device are made uniform.

Title: Operation control device for freezer
Inventor: MOMONO TOSHIYUKI
IPC: F04B49/06
Filed: 1989-10-27
Abstract: PURPOSE:To avoid a stopping operation caused by a thermostat as much as possible by a method wherein when a load-down instruction is given at a minimum step in a normal operating range, a compressor is not stopped at once, but it is kept at a quite low load step for a set time. CONSTITUTION:A volume of a compressor 1 is controlled in its one step for its increasing or decreasing state by a normal operation control means 50 in response to a volume instruction signal outputted by a signal output means 8 and further the operation is adjusted in several steps. Then, when a down- signal is outputted from a signal output means 8 while being kept at the minimum step in the normal operating range, an operating volume of the compressor 1 is forcedly kept at a quite low load step for a specified period of time by a forced volume holding means 51. When the set time elapses by the forced control means 52A, the compressor 1 is thermostatically stopped only when the load-down signal is outputted again from a signal outputting means Th. In the event that either the load-up signal or a keep signal is outputted, the operation is controlled in such a way as the operation returns to its normal operation. With such an arrangement, an accuracy in control is improved.

Title: Aligner and method of exposure, and manufacturing method of device
Inventor: ISHIKAWA JUN
IPC: G03F7/20
Filed: 1999-10-01
Abstract: PROBLEM TO BE SOLVED: To actualize higher precision exposure quantity control by suppressing the influence of variation in the transmissivity of an optical system. SOLUTION: A 1st optical sensor 46 detects the energy quantity of an energy beam EL passing through a lighting optical system 12, and a 2nd optical sensor 27 detects the energy quantity of an energy beam EL having passed through at least part of a projection optical system PL. Then a main controller 50 controls the integrated quantity of energy supplied to a substrate W during exposure according to both detection results. Here, if the transmissivity to the energy beam in the optical path from the 1st optical sensor to the substrate surface (image plane) varies, this variation is reflected nearly accurately on the value standardized, by dividing the detected value of the 2nd optical sensor by the detected value of the 1st optical sensor.  The transmissivity variation of the optical system in the optical path is therefore substantially canceled, to enable high precision exposure quantity control.

Filed: 1990-10-19
Abstract: PURPOSE: To form an electric passage without passing through an inertial body or the moving element of a sensor responsive to crash by providing a sensitive element moving to a second position in response to a deceleration force exceeding an actuation force. CONSTITUTION: When the deceleration force exceeds a set threshold value, it overcomes the restriction force of a field and a metal ball 34 is shifted in the direction of an arrow A along a passage 40. The metal ball 34 touches the forward end of upper contactors 50, 52 substantially simultaneously. Since the forward ends are insulated, electric contact does not take place at the moment of time. The metal ball 34 is shifted in the direction of arrow A until the contactors 50, 52 are bent in same direction to touch bends 58, 60, respectively. Consequently, an electric paths are formed between contactors 48, 50 and 46, 52. These electric paths are utilized for generation of electric signal which is delivered on conductors 14, 16, for example, to a passenger controller 80.
