Title: Optical displaycement sensor
Inventor: OKUYAMA HIROETSU
IPC: G01C3/06
Filed: 1989-11-08
Abstract: PURPOSE:To measure the displacement of an extremely small part with good sensitivity over a wide range by forming the sides of optical fibers for light projection and light reception which face a body to be measured in a sheet shape and arraying them linearly. CONSTITUTION:The sides of the optical fibers 7a and 7b for light projection and light reception which face the body to be measured are formed in the sheet shape and arrayed linearly, so light emitted by the optical fiber 7a for projection from a light projection ellipse 13 on the body 10 to be measured and the optical fiber 7b for photodetection has a light receiving ellipse 14 capable of receiving reflected light from the body 10 to be measured on the body 10 to be measured. The optical fiber 7b for photodetection obtain only reflected light with the opening angle of the optical fibers from a measurement spot where a light projection ellipse 13 and the ellipse 14 are put one over the other. At this time, the measurement spot varies in size in proportion to the distances between the optical fibers 7a ad 7b and the body 10 to be measured and the quantity of reflected light varies, so the displacement is found and the range of front linearity is determined by the array length of the optical fibers 7a and 7b. Consequently, the displacement of the extremely small part can be measured with good sensitivity over the side range.

Abstract: PROBLEM TO BE SOLVED: To make the dimension in the height direction to be small by constituting a device with a cam member for making disk holders move against a chassis in the direction vertical to the recording surface of the disk while engaging with the plural disk holders and also for moving in the direction opposite to the moving direction of the disk holders. SOLUTION: The length of the cam member 30 is equal to the length required for arranging the necessary distances L32, L33 above and below the disk when the disk is reproduced, and the distance L31 is equal to the length that the thickness of the laminated five disk holders is added to the length of this cam member. When the cam member 30 is rotated clockwise for the purpose of housing the 2nd disk in the disk holder 12, the cam member 30 is moved to the lower side along a cam groove simultaneously with the rotation and by the further rotation, it becomes vertically unmovable since the lower side of the cam member is abutted on an engaging pin 18 of the 3rd disk holder 13, consequently the rotation is made while keeping the height as it is.

Title: Device for vapor growth of crystal
Inventor: KONNO NOBUAKI
IPC: H01L21/205
Filed: 1987-11-16
Abstract: PURPOSE:To prevent convection by heat of a susceptor and enable crystal having steep surface to grow, by separating a reaction tube into two chambers to move the susceptor to each chamber alternately. CONSTITUTION:A susceptor 3 is placed in a standby reaction chamber 1a to be heated. In this time, H2 and AsH3 are caused to flow into the chamber 1a and H2, AsH3, and TMG of the desired quantity of flow are caused to flow into a growing reaction chamber 1b. Turning a suscepter holder 4 by 180 degrees when the susceptor 3 is heated to the desired temperature, the susceptor 3 is moved to the chamber 1b to cause crystal to begin to grow. When the crystal completely grows, the holder 4 is turned by 180 degrees to move the susceptor 3 to the chamber 1a. Thus, there is no heating unit 3 in the chamber 1b at this time, preventing the convection due to heat and facilitating the change of gas. And then the flow quantity of the gas is adjusted to the desired value and the holder 4 is turned by 180 degrees to move the susceptor 3 to the other chamber for the multilayer growth of the crystal upon crystal substrate 6.

Title: Display device
Inventor: KIKUCHI ZENTA
IPC: G02F1/1335
Filed: 1998-09-29
Abstract: PROBLEM TO BE SOLVED: To keep sufficient screen luminance even when the luminance of light from a light source is slightly decreased for saving the electric power, in a liquid crystal display device which uses both the light from the light source and external light at the same time to display. SOLUTION: A surface side casing 2 consists of a transparent resin. When external light is introduced from the outside of the surface side casing 2 into the inside of the surface side casing 2, a part of the introduced light is reflected by both reflection plates 41 and 42, then transmitted through a one-way reflection/the other-way transmission plate 25 to be introduced into a light guide body 15. As this introduced light is reflected mainly by a reflector 18, it goes out of a fluorescent tube 17 and behaves in the almost same way as the light which is reflected by the reflector 18. Therefore, most of the introduced light is made incident on the backside of a liquid crystal display panel 1.  As a result, besides the external light made incident from the surface side of the liquid crystal display panel 1, the external light introduced from the outside of the surface side casing 2 into the inside of the light guide body 15 is made to be used.
