Filed: 1999-07-19
Abstract: PROBLEM TO BE SOLVED: To automatically set a direct communication mode when a mobile station moves beyond a communication area in a radio communication system constituted of a base station and plural mobile stations. SOLUTION: In this radio communication system, the reception level of a signal with frequencies F2 from a base station is detected by a first reception level detecting part 27, and when the level is lower than a reference level, it is judged that a mobile station moves beyond a communication area by a first deciding part 34, and frequencies in a modulating part 22 are switched to frequencies F3 exclusive for direct communication, and a signal is transmitted to another mobile station. Each mobile station monitors the signal with the frequencies F3, and at the time of receiving the signal, the data of the reception level are detected by a second reception level detecting part 31, and the signal is transmitted to the mobile station beyond the communication area by the frequencies F3.  The mobile station beyond the communication area receives the signal transmitted from the plural mobile stations. The mobile station beyond the communication area selects the mobile station with the most satisfactory reception level data by a third discriminating part 36 based on the reception level data in the received signals, and execute direct communication with the mobile station by the frequencies F3.

Filed: 1990-08-03
Abstract: PURPOSE:To obtain the dimming device which automatically controls photographic lighting so that the influence of the reflection factor of a subject is reflected by measuring the quantity of light from the subject while measuring the distance to the subject. CONSTITUTION:Range finding data is inputted to a system controller 1 through a range finding means 2.

While a shutter device 11 is opened and a switch 6 is turned off, the integrating process of a light measuring means is started. Further, timer clocking is started and a stroboscopic device 3 starts emitting light with GNS. Then the subject reflected light is passed through a photodiode PD4 and an integral value is inputted to the control ler 1. Then the reflection factor ratio of the subject is calculated from the integral value and a standard integral value to calculate a final integral target value and the lighting is restarted. Consequently, while neither overexposure nor underexposure is caused, the influence of the reflection factor of the subject is reflected.

Title: Dry etching method
Inventor: OKUDAIRA SADAYUKI
IPC: H01L21/3065
Filed: 1987-08-21
Abstract: PURPOSE:To make a side face perpendicular substantially by keeping the surface temperature of a solid so that the difference between the vapor pressure of a reaction product formed by a reaction with a neutral radical and total gas pressure in a reaction vessel is made smaller than a specified value and etching the surface of the solid. CONSTITUTION:A wafer 2 is fixed by a wafer hold-down 5, holding a thermal contact plate 4 on a cooling base 3. Various refrigerants 6 are introduced to the cooling base 5. The temperature of the wafer 2 is changed by the balance between the inflow of energy flux such as plasma, an ion-laser or the like and the quantity of heat flowing in through the thermal contact plate 4. The surface temperature of the wafer is measured by a thermocouple 10. The vapor pressure of an etching gas is made higher than total gas pressure in a reaction vessel, and the surface temperature of a solid is kept so that the vapor pressure of a reaction product shaped by a reaction with neutral radicals is brought 10<4> times as high as total gas pressure in the reaction vessel, and the surface of the solid is etched. Accordingly, a sidewall can be etched vertically without being particularly formed.

Title: Heat treatment system
Inventor: NISHIMURA KOJI
IPC: H01L21/22
Filed: 1999-07-21
Abstract: PROBLEM TO BE SOLVED: To provide a heat treatment system that achieves a stable temperature distribution at the location where semiconductor substrates are arranged within a furnace tube. SOLUTION: A stepped portion 21b is provided at least on the bottom of an inner circumferential surface portion in the vicinity of an opening 6 of a furnace tube 21. The portion 21b serves to guide the air in the radially inward direction, the air entering from the opening 6 and flowing along the bottom. As a result of this arrangement, the air and a process gas introduced into the tube 21 blend with each other at the portion 21b, whereby turbulence occurs. Further, the portion 21b and semiconductor substrates 4 are arranged at a distance so that a region 7 of turbulence will not extend over the substrates 4, thereby preventing the degradation of temperature distribution at the location where the substrates 4 are arranged.

Title: Image forming device
Inventor: SATOU TADASHI
IPC: G03B27/50
Filed: 1981-12-21
Abstract: PURPOSE:To stabilize a running speed, and to prevent generation of flow or blur of a copied image, by equally setting a start running distance and an overrun distance of an optical scanning body, in an image forming device of a reciprocating boh-direction copying system. CONSTITUTION:An optical reading unit 21 executes a going-motion in the direction as indicated with an arrow (a), moves by a distance l, is reversed, executes a returning-motion in the direction as indicated with an arrow (b), and during its time, an image of an original O is optically read. In the reciprocating both-direction copying system, its moving length l makes start running length l1 and overrun length l2 equal, and is set to length which had added available transfer material size lx to said length. The start running length l1 is required for rising to a constant speed from a speed ''0'', and the overrun length l2 is required for deceleration and stop. When setting to l1>l2, the scanning start side at the time of a returning-motion of the scanning body cannot reach a constant speed yet in the start running length l2, therefore, the copied image flows or blurs. By this reason, the start running length and the overrun length of the scanning body are set equally so as to obtain a correct copied image.

Title: Method for visualizing air stream
Inventor: HASHIMOTO TAKESHI
IPC: G01P13/00
Filed: 1985-09-20
Abstract: PURPOSE:To make it possible to accurately observe the state of an air stream in a real time without contaminating inside a clean room, by blowing off fine water droplets toward the space in which the air stream is present from a nozzle in a white smoke like state. CONSTITUTION:The air introduced into the ceiling of a clean room 10 passes through a filter 12 to flow n a working process region 14 and is exhausted from an under-floor ventilation chamber 18 while the air sucked by an air pump 20 is supplied to an ultrasonic humidifier 24 and fine water droplets are blown off from a nozzle 30 through a vinyl tube 28 in a white smoke like state. The laser beam 34 from an argon laser emitting apparatus 32 is deflected and moved at a high speed by the rotation of a polygon mirror 36 to form a laser beam film 38. By this method, because the laser beam impinging against water droplets is scattered and only the certain part of each water droplet is looked as emitting green or blue beam, the pattern of the air stream can be accurately and visually observed.
