IPC: G02F1/13
Filed: 1980-11-25
Abstract: PURPOSE:To eliminate residual air bubbles in a cell by oscillating a liquid substance for display, such as liquid crystal, by an ultrasonic wave when injecting the liquid substance into the display cell. CONSTITUTION:A heated cell substrate 5 is placed in a bell jar 1 and after the bell jar is evacuated, the preheated substrate 5 is dipped in a liquid substance 4 in an injection dish 3.

Title: Device for preventing electrification of target of ion implantation device
Inventor: SAKAI KATSUHIKO
IPC: H01J37/20
Filed: 1984-08-10
Abstract: PURPOSE:To reliably prevent the electrification of a target which might be caused during ion implantation by producing a great amount of low-energy secondary electrons immediately before the target by obliquely irradiating electrons emitted from an electron source upon a secondary-electron-producing electrode installed near the target. CONSTITUTION:Ion beams 15 are implanted into a wafer 20 placed on a disk 19 through a slit 22, a suppressor 21 and a Faraday cup 10. An accelerated electron beam 13 produced from an electron source consisting of a heating filament 11 installed on the side of the Faraday cup 10, is deflected by a magnetic field 14 before being obliquely irradiated upon the area 25 of the Faraday cup 10 located near the wafer 20. As the result, secondary electrons are emitted from the area 25.

Title: Deviation detecting device for correlation image
Inventor: ISHIDA TOKUJI
IPC: G02B7/34
Filed: 1985-07-26
Abstract: PURPOSE:To prevent erroneous focus detection and range finding by discriminating fluctuation of degree of correlation between output patterns of the first and second light distribution detecting device in the periphery of obtained maximum correlation shift position, and not making detection and operation of deviation. CONSTITUTION:The optical system has a condenser lens 6 at an expected focal plane 4 behind a photographing lens 2 or at a position further rear from the plane and has reimaging lenses 8, 10 in further rear position, nd line sensors 12, 14 are arranged on the image forming planes of lenses 8, 10. When the image of an object to be focusd is formed in front of expected focal plane, i.e. front focus, images on the sensors 12, 14 become near the optic axis 18 and come close to each other, and the image of the object is formed behind the expected focal plane, i.e. rear focus, the images become far from the optic axis. When focused, distance between two corresponding points of the two images becomes a specific distance determined by constitution of the optical system of a focus detecting device. In the case where degree of correlation between output patterns of sensors 12, 14 fluctuate around obtained maximum correlation shift position, this is discriminated and detection and operation of the amount of deviation is not made. Thus erroneous range finding is prevented.
