Filed: 1988-04-26
Abstract: PURPOSE:To improve classifying efficiency by providing a dashboard or vortex adjusting piece and a sealing fitting to enclose the top end of the vortex adjusting piece or secondary vanes for assistance to the outside circumference of an upper diffusion plate. CONSTITUTION:Raw materials 25 charged from a raw material charge port 24 enter the top of a lower diffusion plate 17 and are splashed in the outside circumferential direction by the centrifugal force of the plate 17. The greater part of the raw materials move along the rear surface of the upper diffusion plate 16. The classifying raw materials 25 are, therefore, brought into collision against the tapered dashboard 19 provided to the diffusion plate 16 by said dashboard 19, by which the dispersion is intensified and the materials are adequately loosened. The raw materials 25 simultaneously receive the two forces of the diametrical directions; the outward centrifugal force and the inward air resistance in the radial direction. The particle diameter at which these two forces balance each other is determined as a classification point and the particles below the classification point are entrained in the circulating air flow by main vanes 15 and classifying vanes 18 and are recovered by a cyclone effect into a fine powder chamber 21. The air flow is then given swirling by the banes 23 and is hereby risen. The coarse grains classified in a classifying chamber 20 are captured by a circular conical part 33.

Abstract: PROBLEM TO BE SOLVED: To provide a base for a light adapter capable of reducing energy cost by simple and inexpensive equipment without requiring equipment such as an expensive molding machine and a metal mold, excellent in dimensional stability, easy in control and easily manufacturable by performing dimensional finishing by removing a wire after forming a metallic or plastic wire in a bar shape as a matrix by electrocasting. SOLUTION: First of all, a thin bar is manufactured by electrocasting using a metallic or nonmetallic wire 9 as a cathode, and then, the wire 9 is removed by pulling out or pushing out or melting the wire 9, and then, the final finishing is performed by an automatic machine such as an NC machine. Generally, a wire being unmeltable in chemicals and having high tensile strength uses pulling-out or pushing-out, and a wire easily meltable in the chemicals uses melting. Since the wire 9 such as aluminum or the alloy and copper or the alloy easily melt in an acid or an alkali aqueous solution, removal by melting is mainly used. Actually, a strong alkali aqueous solution such as sodium hydroxide and potassium hydroxide of about 10 to 30 w/v% is used.

IPC: H01C13/00
Filed: 1999-04-09
Abstract: PROBLEM TO BE SOLVED: To provide a desired resistance value and to prevent shorting between electrodes, by providing a surface protection layer protecting the surface of a groove formed at the peripheral part of a first conductivity type semiconductor substrate and outer connection electrodes on both surfaces of the semiconductor substrate. SOLUTION: Grooves 12 are formed on a peripheral part on one surface in an N-type semiconductor substrate 2, the surface protection members of glass are put in the grooves 12 and surface protection layers 14 are formed. The specific resistance of the semiconductor substrate 2 is larger than that of metal or it can be controlled by impurity concentration and desired specific resistance can be obtained. For making resistance to be low in a similar way as winding-type resistance, the thickness of the semiconductor substrate 2 is thinned and the area of a first electrode 8 is enlarged. Since the semiconductor substrate 2 is thin, the inductance of a semiconductor becomes small. Thus, resistance of small inductance is obtained by enlarging the area of the electrode 8.  The low resistance of semiconductor resistance is formed by the vertical semiconductor, the electrodes 8 and 10 are arranged on both surfaces of the semiconductor substrate 2, and a part between both electrodes is prevented from being shorted.

Title: Radio communication system
Inventor: NUMAGAMI KOICHI
IPC: H04J3/00
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To enable one-to-one communication to be conducted among plural equipment without the provision of an exclusive base station that manages time slots related to time division processing. SOLUTION: All radio stations are set to a reception state to monitor a current communication state. In the case that a radio station (caller station) starts communication with other stations, a time slot discrimination section 6 confirms an operating state of each time slot. A time slot decision section 7 assigns its own station to a 1st position of a prescribed number of time slots, when other stations make no communication and a transmission section 3 starts transmission of required data. The caller station using the time slot at the fast position acts as a pseudo-base station, and the first time slot is a timing reference for time division processing, when communication is made among other radio stations.  A receiver side station decides a time slot position of its own station based on data relating to the time slot used by the caller station, included in the transmission data and transmits a response signal.
