Title: Optical fiber bundle for lighting
Inventor: OKADA MINORU
IPC: D06M101/00
Filed: 1990-08-23
Abstract: PURPOSE:To prevent an optical fiber from breaking as far as possible and to suppress a rise in the temperature at an incidence end part by charging a specific fixing agent which has high heat conductivity in the gap of the optical fiber bundle at the incidence end part. CONSTITUTION:A material which has a fusion point lower than temperature where optical fibers 1 deform thermally and high heat conductivity exceeding 0.01cal/cm.s.deg is charged as the fixing agent 2 in the mutual gap of the respective optical fibers forming the optical fiber bundle 1 at the incidence end part where the bundle is connected to a light source device 9, and the fixing agent 2 is solidified to fix the respective optical fibers in one body. Consequently, the optical fiber bundle excellently conducts heat generated with irradiation light from a light source to a connecting external cylinder, etc., through the fixing agent 2 and the heat is radiated. The optical fibers are therefore hard to thermally deform and break, and the optical fiber bundle transmits incident light efficiently without decreasing in light transmissivity.

Filed: 1999-08-03
Abstract: PROBLEM TO BE SOLVED: To make the number of times for a power remainder operation con stant by deciding the presence of a wrong person when the specific checking is unsatisfactory with a communication unit. SOLUTION: A base station generates a large prime number (p) and a large (q) are opens them to the public and also generates an element (g) whose rank in a multiplication group Zp is equal to (q) to publicize it to the public.

Then the terminal (i) selects a random number ri and calculates the information xi=gri mod p to transmit it to the base station. The base station selects a random number (e) and broadcasts it to every terminal (i). The terminal (i) calculates the verification information yi=ri+si.e mod q and sends it to the base station.  Then the base station checks X1×X2×...Xn=g(y1+y2+...+yn) (v1×v2×...×vn)e mod p to decide that all authenticated terminals (i) are right when the checking is satisfactory and to decide the presence of a wrong person when the checking is unsatisfactory respectively.

Filed: 1995-08-29
Abstract: PROBLEM TO BE SOLVED: To measure the exact phase difference of a mask substrate formed with a translucent light shielding film on a transparent substrate by providing the prescribed region in the peripheral parts of the mask substrate where mask patterns are not formed with transmissive patterns for measuring the phase difference. SOLUTION: A mask pattern region 21 for production of solid-state elements is arranged near the center of, for example, a mask 20. The mask patterns for mask alignment and the mask pattern regions 22 for managing process conditions are arranged on the peripheries. Further, the peripheries are formed as the regions 23 where the transmissive patterns for measuring the phase difference are arranged. The translucent light shielding film of the desired regions is selectively removed after the translucent light shielding film is uniformly formed on the transparent substrate in order to form transmissive patterns. A laser beam, particle beams, wet etching method, dry etching method, etc., are preferably used for the selective removal thereof.  As a result, the exact measurement of the phase difference introduced by the translucent light shielding film is made possible and the quality control during the course of the production stage is made possible.

IPC: G11C11/409
Filed: 1994-09-14
Abstract: PURPOSE: To realize high integration of semiconductor memory by providing a bit line potential reset circuit from which a precharge voltage generating circuit is omitted. CONSTITUTION: In the semiconductor memory, a bit line BL and a bar BL are connected with a bit potential reset circuit 1.

Filed: 1989-08-30
Abstract: PURPOSE:To reduce the frictional force of a ribbon to stabilize a ribbon running and conduct a stable printing without the possibility of breaking paper by a method wherein a ribbon separator is provided with holes, and the holes are uniformly formed not only on positions opposed to printing pins on a printing head but also on other positions. CONSTITUTION:A ribbon separator 22 provided with a large number of holes 23 is mounted on the front surface of a printing head 6 through a gap for inserting an ink ribbon. The holes 23 are uniformly provided not only on positions opposed to printing pins 9 but also on other positions.

In this manner, the ribbon separator 22 is so constructed as to be uniformly and continuously provided with the relatively small holes 23 including the holes for penetrating the printing pins 9. Therefore, the frictional force of the ribbon can be so reduced that the ribbon can run stably, and ink stains on paper can be also prevented. In addition, the break of the paper caused by the upward movement of the paper or the longitudinal movement of the printing head 6 can be prevented, and a stable printing can be performed.

CONSTITUTION:This discharge device of curable liquid material is equipped with magnetic field generation stators 41a to 41c, a rotor 42 and a means for measuring the number of rotations of the rotor 42 provided at the lower end of a storage tank 1. Further, the discharge device is equipped with a control part 5 which adjusts the pressure of gas from a gas supply source 31 in accordance with the variations of the number of rotations and makes the discharged amount of the curable liquid material constant. Consequently, a rotary torque generates on the rotor 42 on account of the magnetic field generation stators 41a to 41c, and the rotor 42 rotates under the viscous resistance of the curable liquid material. Thus, the rotating speed of the rotor 42 is controlled to be a function of the viscosity of the curable liquid material so that the gas pressure is controlled by the rotating speed so as to allow the discharged amount constant regardless of the viscosity change of the curable liquid material.

Abstract: PURPOSE:To apply sensitivity measurement of plural receivers simultaneously and to reduce the test time by providing an operation electric field strength storage section storing an operating electric field strength of a test object and plural operation detection means. CONSTITUTION:A main control section 1 sets a call number to an encoder prior to the start of the sensitivity test (1). Moreover, a carrier frequency is set to a signal generator 5 (2). An electric field strength (a) is set to an electric field strength storage section 2 and the signal generator 5 (3). Then a call to a receiver 8 is started.

In the presence of the reception reply, the electric field strength (a) is read from the storage section 2 and the result is outputted to an operating electric field strength storage section 2 in relation with the electric field strength (a) with the receiver 8 making the reception reply (5). Then the electric field strength (a) is decreased (6), and the processing from the items (3) above is repeated. When no reception reply exists, the electric field strength (a) is read from the storage section 2 and the value is outputted externally as the sensitivity measuring result (7).
