Title: Information repeater and terminal equipment
Inventor: IOKI SADAO
IPC: H04B10/114
Filed: 1996-02-02
Abstract: PROBLEM TO BE SOLVED: To easily adjust an array on communication states between an information repeater and a terminal equipment and between the information repeaters and to easily monitor the communication state. SOLUTION: When infrared rays are transmitted from the terminal equipment (game machine), an auxiliary repeater 22 receives them in a light-receiving element, a filter circuit amplifiers them and a level display unit 181 level- displays the reception sensitivity of the infrared rays. When the reception sensitivity level of the level display unit 181 is lower than a prescribed level, whether the transmission direction of the infrared rays from the terminal equipment is deviated or a reception direction in the auxiliary repeater 22 is deviated can immediately by recognized on the spot since satisfactory reception cannot be executed. Thus, the worker of array adjustment goes to the terminal equipment and adjusts the irradiating direction of the infrared rays by deviating the transmission direction or the angle of a light-emitting part transmitting the infrared rays.  Thus, the direction adjustment of infrared communication is facilitated, the time of adjustment work is shortened and the efficiency of adjustment is improved.

Abstract: PROBLEM TO BE SOLVED: To shorten time required for the operation of a discharge acceleration means, eliminate variation in acceleration effect, and miniaturize or reduce scale, by providing a plate, which obliquely extends downward from a higher position and reaches the vicinity of a discharging opening, in a container having the discharging opening in the lower end of its conic part. SOLUTION: In the lower end of the conic part 11 of a container main body 1 made of a metal, a discharging opening 12 and a discharging valve 13 are provided and, in the container main body 1, a plate 2 with a specific width is extended obliquely at a specific angle from a higher position to the vicinity of the discharging opening 12. A vibration- or impact-generating means 3 on the external face of the container main body 1 uses a vibration motor, an electromagnetic vibrator, or the like. A bridge of a powder material is caused when the strength of the powder formed into a solid by pressure becomes greater than shearing force that occurs under the conditions of a storage tank, so that a blockade occurs.  By opening the discharging valve 13 and operating the vibrator 3 for a short time the powder material below the plate 2 slidingly falls along the internal face of the conic part 11 without the occurrence of a bridge and is discharged. It shortens the time required for the operation of the vibrator 3, reduces noise pollution and cost, and enables miniaturization, simplification, and the steady and continuous supply of the powder material.

Abstract: PURPOSE:To accelerate a reaction speed and to obtain a high reaction efficiency by setting a distance between the end of a nozzle and the surface of a substrate to a specific value or less and enhancing the pressure of reaction gas in a light irradiation unit. CONSTITUTION:An excitation reaction speed of an optical CVD, optical etching or optical epitaxial growth increases with the gas pressure.
