IPC: G09F9/30
Filed: 1983-07-12
Abstract: PURPOSE:To inhibit a liq. crystal cell from warping and waving, to increase the reliability, and to make the thickness small by using a material having a lower coefft. of thermal expansion and higher rigidity than the material of the 2nd substrate as the material of the 1st substrate. CONSTITUTION:The 1st substrate 5a is made of a material having a lower coefft. of thermal expansion and higher rigidity than the material of the 2nd substrate 5b. An edge of the substrate 5b not connecting with the substrate 5a is notched 7a, 7b-. The material of the substrate 5a is glass, and a plastic sheet such as a sheet of polysulfone, polyether sulfone or polyester is used as the substrate 5b. Since the substrate 5a is made of glass, warping and waving are not caused and the substrate 5b has a high coefft. of thermal expansion, so when both the substrates 5a, 5b are stuck together and heat treated, the substrate 5b is stretched to keep the thickness of a liq. crystal layer 4 uniform and to improve the quality. The concentration of stress is avoided by the notches 7a- to prevent warping and waving, so a thin cell of high reliability and an almost uniform thickness is obtd.

Abstract: PURPOSE:To stably clean by providing a loader and an unloader in a mechanism for conveying a unit to be cleaned along the circumferential route dipped partly in a cleanser to prevent the surface of the cleanser from varying. CONSTITUTION:A unit 10 to be cleaned is bridged over a saddle 8 on a belt 6 of a conveyor 7 from a chute 9, merged in cleaning water 2 in an inverted attitude by a guide 11, and cleaned by a supersonic vibrator 3 on the bottom of a tank 1. The cleaned unit 10 is removed through a chute 12. According to this construction, the surface level of the water 2 does not vary when the unit 10 is telescoped into or out of the water 2 so that the height of the surface level cleaned in the highest efficiency does not change. Thus, it can be stably and effectively cleaned. Since the unit 10 is not telescoped through a cutout 13, an unstable transmission of the supersonic vibration due to supply of excessive water 2 does not occur.

Title: Warming-up correction control method for internal combustion engine
Inventor: TAKEDA MASAO
IPC: F02D41/14
Filed: 1996-05-23
Abstract: PROBLEM TO BE SOLVED: To make an air-fuel ratio rich even when a vehicle runs on a high land and to prevent the generation of the unstable rotation of an engine such as rough idling by detecting the air-fuel ratio by an O2 sensor and, when the detected air-fuel ratio is larger than a stoichiometric air-fuel ratio, by increasing a warming-up correction amount until the air-fuel ratio equals to the stoichiometric air-fuel ratio. SOLUTION: While an engine is operated, an electronic controller 6 judges if a feedback control based on the output signal (h) of an O2 sensor 21 is being conducted or not and, when the answer is NO, it judges whether the O2 sensor 21 is active or not. When the answer is YES, it judges whether an air-fuel ratio is rich, that is, smaller than a stoichiometric air-fuel ratio or not and, if the answer is NO and a base warming-up correction coefficient is not zero, an auxiliary warming-up correction coefficient is increased. The initial value of the auxiliary warming-up correction coefficient is set at 1 and is increased gradually in a lean air-fuel state.  Next, warming-up correction coefficient is determined by multiplying the base warming-up correction coefficient by the auxiliary warming-up correction coefficient, whereby an effective injection period is increased and the air-fuel ratio is changed to a rich side.

Title: Substrate-inclination detecting apparatus
Inventor: SHIBA MASATAKA
IPC: H01L21/027
Filed: 1990-05-21
Abstract: PURPOSE:To detect the inclination of a substrate highly accurately with a compact device by emitting the collimated laser beam from a light source on a substrate, transmitting the regular reflected light from the substrate through an optical coupling part which is provided at a lightguide element, and detecting the intensity of the transmitted light with an optical sensor. CONSTITUTION:When a collimated laser beam 9 is projected under the state wherein a wafer 3 is inclined by an angle alpha, the regular reflected light from the wafer 3 is guided to the linear diffraction-grating type optical coupler 15 of a lightguide element 12 through a galvano-mirror 11. Optical coupling occurs, and the intensity of the laser light which is transmitted through a lightguide 14 is detected with an optical sensor 19. The intensity I of the output of the optical sensor 19 is inputted into a stage controlling circuit 21. The changing amount DELTAalpha of the inclination of the wafer 3 is detected based on the angle alpha of the wafer 3 at a light deflection angle beta when the intensity I of a curve 23 becomes a peak value and the angle alpha0 of the wafer 3 at a reference light deflection angle beta. The signal of the output intensity I of the optical sensor 19 is fed back to a tilt mechanism 5 from the stage controlling circuit 21 through a stage 6. Thus, the inclination of the wafer 3 is accurately corrected to the specified angle alpha0.
