Title: Display element
Inventor: KOBAYASHI HIDEKAZU
IPC: G02F1/1333
Filed: 1991-07-19
Abstract: PURPOSE:To obtain a bright display element with good visibility by combining a polarizer and an element in which a mixture of photopolymerizable polymer precursor and liquid crystal is sealed between two substrates and oriented in one direction to separate the polymer phase. CONSTITUTION:Electrodes 2, 7 are formed on surfaces of flat substrates 1, 8, respectively by vapor deposition, on which polyimide is applied by spin coating, and then calcined at 250 deg.C to form oriented films 3, 6. The surfaces of the oriented films of these substrates are rubbed in one direction and made to face to each other parallel to the rubbing direction with 10mum distance. A mixture of paraphenylphenol methacrylate and liquid crystal prepared at 100 deg.C with 15:85 mixing ratio is sealed in this space and gradually cooled to be oriented. Then the liquid crystal/monomer mixture is irradiated with UV ray at room temp. to separate phases of liquid crystal and polymer to form a transparent element. A polarizer 9 is provided in a manner that the polarizing direction of the polarizer 9 is perpendicular to that of the element. Thus, the number of polarizers can be decreased by one sheet than a conventional element, which makes the whole element bright.

Title: Clean room equipment
Inventor: KATO TAKAAKI
IPC: F24F7/06
Filed: 1999-06-25
Abstract: PROBLEM TO BE SOLVED: To increase an effective space in a clean room and to facilitate control of humidification in the clean room. SOLUTION: A power distribution board 14 for devices 12 disposed in a clean room 5 is situated in a circulation passage 9 and an effective space for the devices 12 installed in the clean room 5 is increased by an amount equivalent to a space occupied by the power distribution board.

Title: Open/close mechanism
Inventor: KUGIMARU TADAHIRO
IPC: G03G21/16
Filed: 1996-07-10
Abstract: PROBLEM TO BE SOLVED: To a properly adjust a space necessary for opening/closing and to improve a preventive maintenance from damage on parts at the time of opening/ closing by providing an open angle setting means for setting an opening angle of a cover of an ejecting part multi-stepwise. SOLUTION: An open/close mechanism MO can set an opening angle at two stages. When a cover 12 of an ejecting part is opened (a) to eliminate JAM, a top end of a groove 102c comes to a position of shaft 102b and the opening angle of the ejecting part cover 12 is fixed. Since a supporting board 102 is leaning against the shaft 102b by gravity, the opening angle of the cover 12 of the ejecting part is limited IF to a small angle. Further, when (b) the cover 12 of the ejecting part for loading/unloading parts such as a reversing unit 10, setting of the opening is changed. When a connected point B of a groove 102c and a groove 102d comes to the position of the shaft 102b, the shaft 102b is inserted into the groove 102d via the connected point B by slightly lifting the supporting board 102. Thus, it becomes possible to open the ejecting cover 12 further.

Title: Production of optical fiber coupler
Inventor: ABE ATSUSHI
IPC: G02B6/28
Filed: 1996-07-10
Abstract: PROBLEM TO BE SOLVED: To lower the polarization dependent loss(PDL) and to shorten the coupler length by previously reducing the outside diameter of optical fiber to a specific range, clamping the optical fiber in tight contact with each other, specifying the heating range, fusing the fiber and stretching the fiber at a specific speed. SOLUTION: The two optical fibers 1, 2 are preferably reduced in the outside diameter to <=120μm and are clamped in clamping parts 5 of a moving stage 3. The fibers are heated and fused to a range of >=8000μm by using a burner 4 and are stretched by moving the moving stage 3 at a speed of <=100μm/sec. At this time, the monitor light from an LD light source 6 of a wavelength 1560nm is made incident on one end of the optical fiber 1. This monitor light is received by photodetectors 9, 10 from two port parts 7, 8 on the opposite side of the optical fibers. The stretching is stopped when the monitor light attains a desired branching ratio. As a result, the PDL value of the coupler is lowered at the respective wavelengths and the PDL 0.2dB band width exhibits a large value. The low PDL is thus confirmed.
