Title: Polarization holding optical fiber coil
Inventor: KASAHARA MASAO
IPC: G02B6/00
Filed: 1990-11-29
Abstract: PURPOSE:To make the distribution of the index of refraction optional by winding an optical fiber around the outer or inner periphery of a cylinder, and diffusing univalent-divalent metallic ions from the outer surface of a glass clad layer of the optical fiber. CONSTITUTION:A single mode optical fiber 11 is wound around a cylindrical frame 14 of metal or porcelain etc. A clad layer 13 surrounds the periphery of the fiber 11 centering a core part 12 having a high index of refraction. An optical fiber coil 10 is thus obtained. Before the fiber 11 is wound around the frame 14, a solvent including a univalent-divalent metal is applied to the outer surface of the frame 14. Then, the fiber 11 is wound over the applied solvent and heated to diffuse the univalent-divalent metal on the surface of the fiber 11. A diffusion layer 17 of the univalent metallic ions is formed. As a result, the distribution of the index of refraction is generated in a cross section of the optical fiber, and the structure allowing only the light of a specific plane of polarization to pass thorough can be manufactured in a simple method.

Title: Keyboard and its wrong input preventing method
Inventor: AOKI YOSHINOBU
IPC: G06F3/02
Filed: 1997-11-20
Abstract: PROBLEM TO BE SOLVED: To prevent a wrong key input operation by invalidating immediately the key input signal when a key switch face is covered with a certain matter. SOLUTION: When a keyboard body 2 is covered with a document 5, the quantity of received light and also the output of an optical sensor 1 are reduced. Thus, a switch circuit 6 cuts its connected key code generation circuit 3 against the reduction of output of the sensor 1. Thereafter, no key code is generated since the circuit 3 is already cut by the circuit 6 even though the document 5 is actually put on the body 2, a key cap 7 touches the document 5, the cap 7 is pushed down by the weight of the document 5 and then a key switch 4 interlocking the cap 7 is turned on. When the circuit 3 is turned off by the circuit 6, a lamp lighting control circuit 10 turns on a lamp 9 to report an operator that the key input is invalid.

Title: Mosquito repelling and refreshing air blower
Inventor: YASUSAKA TOSHIKAZU
IPC: F04D25/08
Filed: 1998-10-19
Abstract: PROBLEM TO BE SOLVED: To install a blower under a desk, a table, a work bench, etc., to operate it to repel mosquistoes at the feet of a person, and to send cool air over the whole periphery of the desk without scattering documents, cigarette-ash, etc., on the desk. SOLUTION: A rotary fan 1 attached to a motor 2 is fixed to a base board 3 so that it is directed upward, and the motor 2 and the rotary fan 1 are protected by a netlike cover 4. An air flow direction adjusting board 5 which can be freely opened or closed, is hinged to the upper face of the cover 4. Thus, since a cool air blown fro the feet of a person to the upper half of the body is softer than that of a conventional electric fan, and the cool air early gives the feeling of coolness and does not stagnate cold, the feet of the person can be prevented from getting cold.

Title: Printing device
Inventor: YOMOGIZAWA MITSUHISA
IPC: G09G5/24
Filed: 1997-11-19
Abstract: PROBLEM TO BE SOLVED: To enhance the processing efficiency of printing data to be inputted from plural printing data generating devices by facilitating a font caching processing at the time charactor codes of plural character code systems are inputted. SOLUTION: A code converting part 9 converts inputted character codes into common internal codes by using conversion tables for every code system. Fonts of the character codes cached in a font cache memory 6 are managed by font cache information added with the internal codes. Since whether supplied character codes are already cached in the memory or not can be detected by making the internal codes as keys, the utilizing efficiency of the cache at the time printing data whose character code systems are different and which are to be inputted from plural printing devices are to be printed by being parallelly processed is enhanced.
