IPC: B01D63/02
Filed: 1990-07-23
Abstract: PURPOSE:To improve the property to discharge trapped clads, etc., and to effectively utilize internal hollow yarn membranes by providing guiding plate projected between many pieces of the hollow yarn membranes in a water collecting pipe. CONSTITUTION:The water collecting pipe 2 is provided with 4 to 8 pieces of the recessed guiding plates 8 of an L shape which are projected radially and incline downward from 90 deg. to about 60 deg. at nearly the same height. Namely, the clads falling from the upper part deposit in the recessed part of the recessed guiding plates 8 and are forced to be discharged to the outside of a filter by a treated liquid at the time of the discharging of the liquid to be treated in the filter. Then, the clads are discharged without being deposited on the surface in the upper part of a frame body 6 and a bundling part 5 of the hollow yarn membranes 3. The central parts of the hollow yarn membranes are surely and effectively utilized at the time of filtration operation or bubbling operation according to this module. In addition, the deposits, such as clads, are easily discharged during the back washing operation or bubbling operation at the time of regeneration after use.

Title: Electrostatic capacitance type proximity sensor
Inventor: ITO HITOSHI
IPC: G01B7/00
Filed: 1994-08-17
Abstract: PURPOSE:To suppress a malfunction due to noise by so setting the oscillating frequency of a pulse generator as not to coincide with a value obtained by dividing the frequency of high frequency noise by natural number. CONSTITUTION:The electrostatic capacitance type proximity sensor comprises a pulse generator 21, two delay circuits 22, 23 connected to the output of the generator 21, and an electrostatic capacity variable type converter (detecting electrode) 3 varying in electrostatic capacitance according to the approach of an object at least at one of the circuits 22, 23. The outputs of the two circuits 22, 23 are decided at the phase by a phase discriminator 26. When high frequency noise is placed on the electrode 3, the oscillation frequency of the generator 21 is set so as not to coincide with a value obtained by dividing the oscillation frequency of the high frequency by natural number. Thereby, even if it conforms to the timing for deciding the phase difference of the circuits 22, 23, it does not conform continuously to the same timing, malfunction of the sensor output does not occur by a filter 30 connected to a D-type flip-flop 26.

Abstract: PURPOSE: To realize various displays with one display device and to improve the operability by switching a higher-order display mode to a lower-order display mode only for a prescribed time in response to the operation which adjusts the sound volume, the balance state, or the like during the operation in the higher-order display mode.

Title: Fabrication and inspection method for side emission led array
Inventor: NOBORI MASAHARU
IPC: H01L33/30
Filed: 1995-07-28
Abstract: PROBLEM TO BE SOLVED: To form a dicing mark indicating a dicing position accurately and facilitating the inspection of overdicing or insufficient dicing for deciding whether an array can be accepted or rejected. SOLUTION: Impurities are diffused into an N-type layer 1b formed on the surface of an underlying semiconductor 1 using an anti-diffusion film thus forming a P-type layer 11. The P-type layer 11 and the N-type layer 1b form a PN junction constituting a light emitting part. A P side electrode 14 is formed on the P-type layer 11 and an N side electrode 15 is formed on the rear surface of underlying semiconductor 1. At the same time, dicing marks 6, 7 are formed in alignment mark regions 5-1, 5-2 using the anti-diffusion film for forming the light emitting part. Since the dicing marks 6, 7 are made at a predetermined distance from the light emitting part and contain no alignment error, dicing can be carried out at an accurate position.

After that, the steel is extracted and immediately rolled at a temp. of Ar3 point or above at 50-70% draft, which then is cooled at 1-10 deg.C/sec cooling rate down to 250-600 deg.C, followed by air cooling. In this way, the grains in the center of plate thickness of the steel plate are refined and toughness can be improved over the whole plate thickness.

Inventor: OGAWA HIROTERU
IPC: G01B11/30
Filed: 1994-08-18
Abstract: PURPOSE:To provide a method of cleaning a semiconductor device in which the flatness of the surface of a semiconductor layer at an initial stage can be maintained or enhanced in a wet cleaning treatment which is simple and suitable for a batch treatment. CONSTITUTION:The surface of a silicon layer is cleaned by using a hydrofluoric acid aqueous solution which has been diluted with pure water whose dissolved oxygen amount is 10ppm or lower. The flatness of the surface of a semiconductor layer at an initial stage can be maintained or enhanced. Since a cleaning method is a wet cleaning treatment, it is simple and suitable for a batch treatment. When the volume ratio of oxygen in a gas coming into contact with the hydrofluoric acid aqueous solution is set at 21% to lower, the dissolved oxygen amount of the hydrofluoric acid aqueous solution can be maintained.

Title: Helix type traveling-wave tube
Inventor: YOKOI KAZUHIDE
IPC: H01J23/48
Filed: 1991-08-05
Abstract: PURPOSE:To improve a connection struction of an in/out end part of a helix of a helix type traveling-wave tube with a cylindrical coaxial line. CONSTITUTION:A helix 3 is supported in an outer conductor 5 forming a vacuum container by a helix support column 4. An end part of the helix 3 is welded with an end part of a cylindrical coaxial inner conductor 1 through a metal tape 2. The end part of the cylindrical coaxial inner conductor 1 is chamfered planely in the width of the metal tape 2, so it is welded with the metal tape at their plane surfaces. Welding the metal tape with the cylindrical coaxial inner conductor is thus facilitated, and the strength of a welded part is increased compared to conventional devices. Reflection of a high frequency power at the welded part is less likely to occur, thereby the electric characteristics can be improved.

Title: Cause investigating system
Inventor: IMAMURA MAKOTO
IPC: G06F17/30
Filed: 1988-08-04
Abstract: PURPOSE:To investigate cell causes to have resulted in an empty set by referring to the final condition of a partial set table when the combination of conditions to be retrieved does not exist and providing a response generating part to prevent the cause why the retrieving result of the combination of the first applied retrieving conditions is the empty set. CONSTITUTION:A partial set table generating part 2 generates the partial sets corresponding to the all combinations of retrieving conditions 1 as a bit column, and a partial set table 3 added with a discriminating symbol to indicate the success of the retrieve is generated on each bit column. Based on the success failure of the retrieve executed by realizing the propagation of the elimination of the two bit columns with the use of a bit operation, a partial set table updating part 7 finds a combination whose retrieving result is discriminated not to be the empty set or to be the empty set, updates data base 6 thereafter. That is, by feeding back a trial result to the partial set table 3 of the retrieving conditions 1, the number of time of trials of the data base retrieve is suppressed to a minimum, and the all causes are detected. Thus, the all causes to have resulted in the empty set can be investigated.

Title: Power converter
Inventor: YAMAMOTO TOUMA
IPC: H02M7/48
Filed: 1992-07-22
Abstract: PURPOSE:To suppress voltage distortion corresponding to harmonic of load by composing the terminal voltage of load as the combination of an output from a power converter having lower switching frequency and an output from an auxiliary power converter having higher switching frequency thereby quickening control response. CONSTITUTION:An adder/subtractor 401 outputs a difference between an output voltage reference 303 and terminal voltage of a load. A band-pass filter detects a voltage difference component in a frequency band (corrective frequency band) which can not pass through a low frequency inverter 1 but can pass through a high frequency inverter 11. When a detected signal is multiplied by K at an amplifier 503 and fed to a PWM modulation circuit 501, the high frequency inverter 11 outputs a voltage proportional to voltage distortion in reverse phase. The output is passed through an AC filter in the high frequency inverter 11 in order to remove ripples and then added to the output voltage from the low frequency inverter 1 through a transformer 15. Consequently, voltage difference is reduced by a factor of about K as compared with a case where power is fed only through the low frequency inverter 1.
