Filed: 1980-12-17
Abstract: PURPOSE:To make it possible to establish temperature detecting sensitivity and a detecting range by selecting angle theta formed by the propagating direction of light in an optical anisotropic crystal and the optical axis of the crystal in the range of 0<theta<pi/2. CONSTITUTION:An optical pulse irradiated from a light source 1 is linearly polarized through an optical fiber 3 and a polarizer 4, and inputted to the one side of the temperature detector 5 comprising the optical anisotropic crystal. The light which has passed temperature detector 5 is fed to an analyzer 6, wherein the phases of the two light waves having vertical vibrating direction are detected. The light is guided to a light detector 7 through a lens 3' and an optical fiber 2'. Since there are two optical axes is in the optical anisotropic crystal 5 in the case of two axis crystal the direction of the propagation of light is determined by two angles theta1 and theta2 which are formed between two light axes and the propagating direction of light. The sensitivity and the measuring range are established by said theta1 and theta2.

Title: Ceramic sheet and its production
Inventor: HATA KAZUO
IPC: H01M4/88
Filed: 1999-06-24
Abstract: PROBLEM TO BE SOLVED: To obtain a ceramic sheet which is less apt to generate cracks and spalling, even when receiving large lamination loads and thermal stresses, by controlling the heights of burrs on the periphery of the ceramic sheet to a specific value or less, wherein the heights of the burrs are determined by irradiating the surface of the ceramic sheet with laser light by the use of a laser optical three-dimensional shape measurement device and then three-dimensionally analyzing the reflected light. SOLUTION: The burr heights on the periphery of the ceramic sheet are controlled so that the difference between the highest point and lowest point of the ceramic sheet in an area between the peripheral end and the 3 mm-inner place of the ceramic sheet is ±100 μm or less, preferably ±5 μm or less. The value is desirably reduced by lowering the heights of burrs generated on a punching process, reducing inner stresses generated at the punched site, and further equalizing the releasing speed of a thermal decomposition gas over the whole surface of the ceramic sheet on burning.  The ceramic sheet has excellent lamination load resistance and excellent thermal stress resistance which are required for component elements such as a solid electrolytic membrane for a flat plate-like solid electrolyte type fuel battery, and can prevent the generation of cracks and spalling on operations.

Filed: 1996-07-09
Abstract: PROBLEM TO BE SOLVED: To provide a wireless keyboard system which can communicates with a plurality of central processing units without confusion through simple operation by using only one wireless keyboard. SOLUTION: At the time of setting the correspondence relation between a central processing unit 11 and wireless keyboard 1, a keyboard connection designating switch 12 is pressed. When the switch 12 is pressed, an infrared transmitting-receiving section 15 transmits an optical signal composed of infrared rays by using a random number generated from a random number generating section 13 as an ID code. The keyboard 1 initializes and stores the ID code so far held by the section 15 when the section 15 receives the optical signal and the key information inputted from the key input section 3 of the keyboard 1 is transmitted from another infrared transmitting-receiving section 2 after the ID code is added to each input.  Upon receiving the key information together with the added ID code, the unit 11 identifies the added ID code and, only when the added ID code is coincident with its own ID code, inputs the key information.
