Title: Multiple room type bag filter
Inventor: MORITSUGU YOSHIHARU
IPC: B01D46/04
Filed: 1979-04-04
Abstract: PURPOSE: To discover damaged filter cloth easily when the filter cloth is damaged, replace it with new one and to prevent the lowering of work efficiency by a mechanism wherein a clean room is divided into a plurality of rooms in a bag filter belonging to a type which the outside of the filter cloth is stained.  
     CONSTITUTION: A plurality of cylindrical filter cloth 12 is mounted into a cloth chamber 11, and air containing dust is let pass through the inside from the outside of the filter cloth 12 through a dust chamber 13, and exhausted to the outside by means of a blower 16 through clean rooms 9aW9c and backwash dampers 14aW14c. The dust contained in the air adheres to the outside of the filter cloth 12 and is filtered, and is received in the dust chamber 13. Since the damage of any of the filter cloth of the clean room of the backwash damper is grasped if the backwash dampers 14aW14c are successively opened and the formation of dust is stopped when one among a plurality of the filter cloth 12 is damaged, the damaged filter cloth can be repaired without halting other normal bag filters, and the lowering of the work efficiency of the whole bag filter prevented.

Title: Manufacture of gate array
Inventor: SAKASHITA TOSHIHIKO
IPC: G06F17/50
Filed: 1989-02-21
Abstract: PURPOSE:To shorten a development period of a gate array by a method wherein CAD pattern data is divided into first CAD pattern data which surely exists even when types are different and second CAD pattern data which is inherent to the type, and a pattern of the first CAD pattern data is processed in advance. CONSTITUTION:When an Al wiring part on a second layer is formed, CAD pattern data 1a which is inherent to a gate array is transformed in advance into CAD pattern data 1b whose negative and positive have been reversed. When CAD pattern data 2 which is different according to its type is substracted from the pattern data 1b, CAD pattern data 3 whose negative and positive have been reversed is formed. The pattern data 3 is transformed into data for electron-beam exposure use; the Al wiring part on the second layer is formed by using an electron-beam aligner. Accordingly, it is not required to handle the CAD pattern data 1a which is inherent to the gate array whenever the type is different; an amount of data to be handled is reduced. Thereby, a treatment time of the pattern data and a development period of the gate array are shortened.

Title: Method and device for cutting metal tube
Inventor: TANIMOTO SEIJI
IPC: B23D47/00
Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To provide a method of cutting a metal tube capable of inhibiting a generation of burr at both tube ends of a cut portion clamping a blade in a metal tube and inhibiting an abrasion of the blade. SOLUTION: In this method of cutting metal tube, when a metal tube P is cut using a blade, the blade 2 and the metal tube P are approached at a constant speed and a cutting is started from one side of the metal tube P while a neighborhood clamping a cutting position of the metal tube P is retained at the same height as a conveying height by a placing base 3. When the blade is relatively moved from an inner surface at the other side of the metal tube P to a position of 2-5 times in comparison with a thickness t of the metal tube P, a relative movement speed of the blade and the metal tube P is increased 1.05-1.30 times than the times of cutting starting.

Title: Constant temperature environmental device provided with dehumidifying mechanism
Inventor: NANAUMI KAZUYUKI
IPC: F24F3/14
Filed: 1983-03-11
Abstract: PURPOSE:To improve the heat exchange efficiency and the use and working efficiency of the titled device by a method wherein a temperature adjusting cooler is made to act as a secondary cooler and a primary cooler is provided within an open air introducing passage separately from the secondary cooler. CONSTITUTION:The open air sucked into an open air introducing passage 15 by a blower 4 for the purpose of compensating the open air discharged from an opening 3 is cooled and dehumidified by the primary cooler 16 before it is mixed with the cool air sucked from an environmental chamber through an air flow passage 9a. In other words, if the surface temperature of the primary cooler 16 is adjusted at a value slightly higher than 0 deg.C by a pressure reducing mechanism of a cooling circuit, the open air is cooled as it passes through the primary cooler 16 to thereby lower the dew point so that the dew of water contained in the open air is deposited on the surface of the primary cooler 16 and is discharged from a drain pipe 17. Accordingly, the amount of frost on the secondary cooler reduces sharply so that the elevation of the temperature of the temperature adjusted air resulting from the heating and melting the frost at the ordinary operation is controlled to a minimum and the accuracy of the temperature control and the working and use efficiency of the device are improved to a remarkable degree.

Title: Acoustic holography device
Inventor: YONEYAMA MASAHIDE
IPC: G01H3/00
Filed: 1982-03-16
Abstract: PURPOSE:To improve degradation in quality of regenerated image due to undesirable speckle noises, by using spherical wave sound sources whose number is equal to the number of samples. CONSTITUTION:On a sound source distributing plane 2, the sound sources 2-1-2-n, whose number is the same as the number of sample points 1-1-1-n, are arranged at the positions, which are symmetrical to a wave receiving point 3' with respect to the sample points. The spherical waves are sent from the sound sources to a body 1. Then the reflected waves from all the points of the body are converged at one point 3' on a wave receiving plane 3. Therefore a sound receiver is placed at this point and the sounds are collected. Then the sound receiving point is moved, and the position of each sound source is corrected. That is, the position of each sound source is corrected so that the reflected waves, which are obtained from the sample points when the sound sources 1-1-1-n send out the sounds, are converged at the new wave receiving point. By using the many sound sources in this way, the same procedure is performed along the entire wave receiving plane 3, and the sounds are collected. Therefore all the reflected waves from the sample points reach each wave receiving point. Thus the same state, where the sound waves are subjected to diffused reflection at the surface of the body 1, can be obtained, and the hologram can be formed.

Title: Communication system for time-series information
Inventor: MASUDA YOSHINARI
IPC: H04N19/169
Filed: 1994-03-11
Abstract: PURPOSE:To enable communication of time-series information of as high quality as possible and prevent its reproduction from being broken by detecting the free capacity of a buffer and determining an encoding parameter determining compression rate on the basis of the detected value. CONSTITUTION:A compression rate control unit 11 dynamically varies the compression rate of an encoding part 101 according to the variation in the relative data amount of composite data in the buffer 123. Namely, a data amount detection part 111 detects how much the composite data in the buffer 123 increases or decreases in amount and how much data occupies the buffer capacity on the basis of proprortion and sends them to an encoding parameter variation part 112. The variation part 112 determines an optimum encoding parameter from the detected value and current encoding parameter and informs the encoding part 101 of that. Then the encoding part 101 dynamically varies the encoding parameter and varies the compression rate of the time-series information. Consequently, the time-series information of quality corresponding to the data amount in the buffer 12 is sent to a reception device 12 through a communication path 13.
