Title: Powder coating method for cylindrical internal surface
Inventor: YOSHIDA TADAO
IPC: B05D7/22
Filed: 1993-02-25
Abstract: PURPOSE:To form the uniformly stuck layer of powdery particles on an annular face extending over 360 degrees on a cylindrical internal surface at high speed by radially warping the flow of charged coating powder, annularly blowing powder to electrostatically stick the same and relatively transferring a warped face and the cylindrical internal surface. CONSTITUTION:Powder coating of a cylindrical internal surface 20 is performed by the following method. When coating powder 12 is sent in the direction A shown in an arrow through a pipe 10 constituted of insulating material such as resin, coating powder 12 is rubbed on the wall surface of the insulating material until the same reaches the tip part of the pipe 10 and sufficiently charged. A poppet valve-shaped warping body 15 which presents a smoothly curved conical warping face 14 is supported by a shaft part 16 and arranged in the opening end of the tip of the pipe 10. The charged coating powder 12 pushed out in the direction A shown in the arrow is warped in the direction radially spread by the conical warping face 14. While coating powder 12 is annularly blown on the cylindrical internal surface 20 and electrostatically stuck, the warping face 14 and the cylindrical internal surface 20 are relatively transferred in the direction of the shaft 16.

Title: Burst transfer system of dma
Inventor: MIYOSHI TETSUO
IPC: G06F12/02
Filed: 1992-02-12
Abstract: PURPOSE:To solve problems of a page boundary in high-speed page mode without detecting row address switching by an external circuit by setting information regarding a change of pages in a register in a DMA controller in advance. CONSTITUTION:A main storage part consists of a DRAM 1 and data transfer by DMA is performed by using the high-speed page mode. Control over operation in the high-speed mode is performed by a memory controller 2 according to whether or not an HsA* signal is outputted from the DMA controller 3. The HsA* signal is an output signal based upon the previously set contents of the register in the DMA controller 3. Namely, information required for the page boundary where the row address is switched is initially set in the register in the DMA controller 3 to perform burst transfer according to the set information in the register in the DMA controller 3 without detecting the change of pages.

Filed: 1982-04-09
Abstract: PURPOSE:To prevent previously the destruction of data or a system breakdown, by cutting off a faulty bus line in case a fault arises among the bus lines and at the same time by informing the detection of the fault to a data processor. CONSTITUTION:The state of a bus line 4 is always monitored by a bus fault detector 2 which detects the presence or absence of a bus fault. A deciding circuit 205 detects the generation of a fault in case the degeneration is produced down to a real value level in a service signal (CONTm+ACK) of a signal line of an input/output bus 4.

IPC: F16L55/18
Filed: 1978-05-19
Abstract: PURPOSE: To make it possible to move various types of tools inside, for example, a vertical pipe passage, by reducing its slipperiness compared with wheels or rollers.  
     CONSTITUTION: First, by operating valve 13, a compressed fluid is sent to expansion chamber 3' from inlet pipe 17 via conduit 1. By this, diaphragm 3 expands and comes into close contact with the inner wall of pipe 2, which makes the moving part (the self-traveling part) of the device into the unmovable state. Next, by operating valve 15, the compressed fluid is poured into bellows 4 via conduit 1". Then,  bellows 4 expands, and while pressing spring 7, it pushes cylinder 11 forward. Next, the moving part is made into the unmovable state by operating valve 14. Then, by operating valves 13 and 15 properly, cylinder 6 is made to advance. Finally, by operating valve 14, it is restored to its former state. By repeating this cycle, it is possible to advance the moving part step by step.

Title: Continuous rolling method
Inventor: MIYASAKA KIYOTO
IPC: B21B1/28
Filed: 1980-05-07
Abstract: PURPOSE: To increase a rolling reduction and to improve a production capacity by driving a rolling roll of an intermediate stand with a large power in order to carry out a rolling work under a condition fittable to the rolling characteristics.  
     CONSTITUTION: In case of continuously rolling a metal with three or more rolling stands, the rolling power of each stand is distributed so as to make that of the second stand 2 the largest, that of the third stand 3 middle and that of the first stand 1 the smallest; by thus arranged rolling power the rolling roll of each stand is driven for carrying out a continuous rolling work for a sheet 9 to be rolled. Since the sheet 9 to be fed to the second stand 2 is hardened and the friction resistance of its surface is made small by the rolling work of the first stand 1, a large rolling load can be applied to the sheet 9 by the second stand 2. The reason of driving the third stand 3 with a small power is because the rolling load must be limited in case of a shape controlled rolling work and a rolling work with a dull roll.

Abstract: PURPOSE:To make, with good reproducibility, a through hole, having a fine opening diameter satisfying a prescribed range, on a semiconductor substrate by a method wherein the termination time of a wet etching process is decided on the basis of the change in concentration of a prescribed element constituting a material, to be etched, which has been dissolved in an etching solution. CONSTITUTION:The termination time of a wet etching process which is executed during a manufacturing process of a semiconductor device is decided on the basis of the change in concentration of a prescribed element constituting a material, to be etched, which has been dissolved in an etching solution. For example, when a through hole is to be made at a GaAs substrate 10 by a wet etching method, a part of an etchant 11 is always fed to a plasma torch 14 inside a detection apparatus 13; the fed etchant 11 is excited at a high temperature of a plasma and the light is emitted. The light-emitting signal is transmitted to a monochromator 15 at the next stage; the light-emitting signal of GaAs is extracted; the signal is processed at a photometric part 16; the result (emitted light intensity) is recorded in real time by using a recorder 17 as a change with the passage of time. The time tA to when the through hole has been made is obtained from this record; in addition, the termination time tE of the etching process is calculated; the etching process is terminated at this time tE.

Filed: 1981-04-23
Abstract: PURPOSE:To stirr and mix monodisperse fine particles uniformly in good efficiency by the turbulent flow of dry air by introduced dry air in a condition opposed to a filter in the heating part of monodisperse fine particles. CONSTITUTION:A dry particle send-out pipe 6 is provided to the upper side of a drying pipe 5 subjected to heating control by a heater and a dry air introducing pipe 7 is provided to the lower end thereof but, to the intermediate part between both pipes, a porous filter such as a glass filter 8 or the like is provided.
