Inventor: SAKAIGAWA AKIRA
IPC: G02F1/1333
Filed: 1996-12-19
Abstract: PROBLEM TO BE SOLVED: To realize gradation display of a liquid crystal display element by making domain size smaller than pixel size and uniformizing domain distribution over a wide area. SOLUTION: The liquid crystal display element is manufactured by injecting a mixture of a ferroelectric liquid crystal (FLC) composition and a monofunctional monomer between an electrode substrate 9 consisting of a substrate 1, an electrode L, an oriented film 5 and a polarizing plate 7 and an electrode substrate 10 consisting of a substrate 2, an electrode S, an oriented film 6 and a polarizing plate 8. After the mixture is heated at a temp. at which the FLC composition shows a nematic phase or an isotropic phase while irradiating the mixture with UV to polymerize the monomer, the liquid crystal display element is cooled. In such a manner, an isotropic structured body giving locally different threshold characteristics is formed to a striped structure in the mixture to form a liquid crystal layer 12.  The striped structure is formed by holding polymers formed by polymerization between the smectic layers of the FLC composition during cooling process.

Title: Scroll type fluid device
Inventor: UENO HIROMICHI
IPC: F01C1/02
Filed: 1990-11-30
Abstract: PURPOSE:To prevent end plates from being made in contact abnormally with laps by providing a connecting means to connect both scrolls to each other so that a follower scroll is rotated in synchronous with a driving scroll and also providing a counterweight at the back of the end plates, to eliminate deformation of the end plates. CONSTITUTION:When driving side engaging members 71 are rotated by rotating a drive scroll 3, either of the engaging members 71 is made in contact with a follower side engaging member 72 to rotate it to transmit a rotational force of the drive scroll 3 to a follower scroll 4. By this, a working chamber between both laps 32 and 42 is contracted as it is moved toward the center of it to compress fluid. Also a moment to deflect end plates 31 and 41 to their rear side is produced in this rotational driving. Since a counterweight 9 is provided at the back of the end plates 31 and 41 and a moment to deflect the end plates 31 and 41 to their front side is produced by it, however, these both moments are offset with each other and the end plates 31 and 41 are rotated without being deflected.

Filed: 1992-11-26
Abstract: PURPOSE:To enable swirl intensity to be regulated without complicating structures around a cylinder liner. CONSTITUTION:Each low swirl scavenge port 8A and each high swirl scavenge port 8B are alternately provided for a cylinder liner 3, and concurrently rings 14A and 14C which selectively opens/closes the scavenge ports in response to a loading range, are provided around the cylinder liner 3, so that only the low swirl scavenge port 8A is used at the time of low loading (O to a), only the high swirl scavenge port 8B is used at the time of intermediate loading (a to b), and all scavenge ports are used at the time of high loading (b to-).

Title: Optical semiconductor integrated circuit device
Inventor: ARASE KENICHI
IPC: H01L27/15
Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To make smaller the area of a chip without causing the malfunction of an optical semiconductor integrated circuit device due to light, which is incided in the peripheral part of a semiconductor substrate, by a method wherein a second conductivity type semiconductor layer on the peripheral part of the substrate is separated from an element formation region through a first conductivity type element isolation layer to put a dummy photodiode in an electrically floating state. SOLUTION: Electrons generated in an N<-> epitaxial layer 2a-1 and a depletion layer are stored in a P-N junction capacity and are not injected in an N<-> epitaxial layer 2. Roughly speaking, if light is not incided in a P-type element isolation layer between the layers 2 and 2a-1, there is not possibility of the malfunction of an optical semiconductor integrated circuit device. The reason why a dummy photodiode is divided into a plurality is for a diversification of risks and an increase of the storage capacity of the dummy photodiode. If the width of second P-type element isolation layers 4b-1 and 4h-2 is formed two times wider or narrower than the thickness of an N-type epitaxial layer, it is possible to increase the storage capacity. The larger the storage capacity is, the larger the critical value of the quantity of light, which induces the malfunction of the device, can be made.
