Title: Manufacture of superconductive wire
Inventor: TAKANO ICHIRO
IPC: C01G3/00
Filed: 1987-11-25
Abstract: PURPOSE:To manufacture an oxide compound superconductive wire having high critical current density by melting a raw material of an oxide compound superconductor and linearly extruding this melt into an oxygen atmosphere or a mixed gas atmosphere consisting of oxygen and fluorine through a nozzle for being solidified. CONSTITUTION:A raw material A is housed in a crucible 3. Next, a cover 2 is mounted and a heater 5 is activated. At a point of time, when the raw material A inside the crucible 3 is melted by an activated heater, oxygen gas is made to flow inside an isolating container 1 at a prescribed flow rate, while filling the upper space inside the crucible 3 with inert gas having the prescribed pressure. In this way, when the upper part of the crucible 3 is pressurized, the raw material A is linearly extruded downward from the nozzle 4. The space, in which this extruded wire rod B advances downward, is filled with oxygen. Accordingly, oxygen is diffused to permeate the inside of the wire rod B. In the meantime, a compound superconductor layer is formed inside the wire rod B. Next, the wire rod B passes through a cooling pipe 20 to become a solidified wire rod. Here, a mixture of yttrium, barium and copper is used for the wire rod B.

Title: Method of controlling group control elevator
Inventor: AOKI KENICHI
IPC: B66B1/18
Filed: 1987-11-24
Abstract: PURPOSE: To service all floors sharingly with always operable elevators by selecting a shared floor predetermined based on each information just before a failure and by automatically recording call from the shared floor, at the failure in each machine control device. CONSTITUTION: Two elevators, A machine and D machine, are assumed to be in an inoperable condition due to any failure or operation stop. When failures occur in a landing call system or a group management device G in this condition, each of machine control devices CA-CF receives failure signals from the group management device G, or the signals from the group management device G are stopped, and therefore, learns the occurring of failures in the group management device G. Each of machine control devices CA-CF selects a shared floor predetermined based on each information just before a failure from the group management device G. Thus, operable elevators, or B, C, E, F machines, automatically share all floors.

Title: Multistage centrifugal compressor
Inventor: MIURA HARUO
IPC: F04D17/12
Filed: 1991-11-13
Abstract: PURPOSE:To make small the flow velocity and the noise when the fluid discharged out of an impeller collides against the vane of a diffuser without lowering the efficiency of a compressor by installing the diameter of the inlet of the diffuser vane nearest to a discharge nozzle outside of the other ones. CONSTITUTION:For a multistage centrifugal compressor, many sheets of impellers 4 and 4c are attached to one rotary shaft. And, the fluid compressed with the left impeller in the figure is discharged from a nozzle, being compressed with each impeller 4 and 4c at the right in order. On the other hand, each diffuser 9 and each vane 7 and 8 are arranged outside of each vane 4 and 4c. In this case, the diameter of the inlet of the vane 8 nearest to the nozzle 6 is installed outside of the diameters of the inlets of the other vanes 7, whereby it is made relatively larger. Hereby the flow velocity when the fluid discharged from the impeller 4c collides against the vane 8 is made small, whereby the noise at collision is made small. Moreover, at the same time, the efficiency of the compressor is prevented from falling.

Abstract: PROBLEM TO BE SOLVED: To allow downsizing and thinning by setting vibration tracks of a vibration mass gravity center approximately linear so as to cancel vibration inertia force and providing an excitation electrode on a surface in a bending shape, when a plurality of vibration legs freely vibrate. SOLUTION: Vibration legs 1R, 1L are respectively directed to free ends 4R, 4L from fixed ends 2R, 2L and partitioned with spring portions 31R, 31L, 33R, 33L for each bent portions, excitation electrodes 6R, 6L are provided on peripheral 4 surfaces of the spring portions 31R, 31L. A vibrating body is made to hypothetically freely vibrate, and a shape or the like is set so that total of inertia forces at respective detail parts calculated in a finite element method are cancelled vertically and reversely to a symmetric shaft SA. When the vibrating body rotates in a surface, Coriolis forces FR, FL act to gravity centers GR, GL of added masses of the vibration legs 1R, 1L, and lines of action become moving diameters rR, rL. Because axial lines of the spring portions 33R, 33L are far from a center of rotation, distances of the moving diameters rR, rL are longer, large Coriolis forces are applied to the entire length, and high sensitive detection is allowed.

Filed: 1993-11-02
Abstract: PURPOSE:To provide a wafer cleaning apparatus in which the input flow of cleaning liquid keeps its speed without stagnating so that extraneous particles can be completely removed from a wafer. CONSTITUTION:Cleaning liquid is supplied to a tank 3 through a port 5 underneath a carrier 2 that holds a wafer 1.

The holes 8 in the baffle 6 are such that one in the center is the largest and their sizes decrease with the distance from the center. In other words, the flow rate of the liquid is the greatest in the center, so that peripheral flows are prevented from returning downward to the center.
