Title: Water treatment method
Inventor: NISHIKAWA MITSUHIKO
IPC: C02F1/38
Filed: 1989-09-12
Abstract: PURPOSE:To remove water-bloom and invisible water-soluble organic matters as well and to enable decomposition of ammonia and removal of malodor by stirring and mixing water treatment liquid containing a large amount of natural mineral ions and gases to diffuse them into water to be treated. CONSTITUTION:Muddy sediments 22 are deposited at the bottom of ponds, lakes and marshes 21. An agitation-mixing device 24 is provided in the water to be treated 23 in the pond. An injection pipe 27 from a water treatment liquid tank 26 and air pipe 29 having an air port 28 above the surface of water are connected to the device 24.

IPC: B01D29/62
Filed: 1989-09-12
Abstract: PURPOSE: To execute filtration while averting the clogging of a filter membrane by generating a vacuum source more powerful than a vacuum source which can be created in a first chamber within a second chamber and passing a suspension through the pores of the filter membrane, thereby parting the particulates in the suspension from the filter membrane. CONSTITUTION: This apparatus has the first chamber 72, a vessel which forms the second chamber 78 thereon, the filter membrane 80 which is disposed between the chambers 72 and 78 and a means for generating the vacuum in the chamber 72. The vacuum source more powerful than the vacuum source created in the chamber 72 is generated in the chamber 78. Further, the liquid phase portion in the suspension is passed through the pores of the filter membrane 80 and on the other hand, the particulates in the suspension are parted from the filter membrane 80 by the more powerful negative pressure created by the more powerful vacuum in the chamber 78. As a result, the suspension contg. the particulates is withdrawn from the chamber 78 while the clogging of the filter membrane 80 is averted.

Title: Acid-electrolyte fuel cell
Inventor: SEGAWA NOBORU
IPC: H01M4/86
Filed: 1983-12-15
Abstract: PURPOSE:To improve the characteristic of an acid-electrolyte fuel cell by increasing the area where the solid, the liquid and the gaseous phases coexist by controlling the wettability of the electrode by an acid electrolyte such as phosphoric acid. CONSTITUTION:The contact angle (theta) of an electrolyte 5 for electrodes 1 and 3 is adjusted to be within the range of 110 deg.-50 deg. by the following method. A surface active agent is applied to the surfaces of the electrolyte 5 and the electrodes 1 and 3 when the electrode base material has an excessively low wettability by an acid electrolyte such as phosphoric acid, while a surface active agent having different properties from the above surface active agent is used for an electrode base material having an excessively high wettability. When the above contact angle (theta) is larger than 110 deg. or smaller than 50 deg., the wettability becomes either excessively high or excessively low and the three-phase electrification product can not be increased and therefore it becomes impossible to improve the characteristics of the battery. For the surface active agent used in this invention, any one of an anionic, a cationic, a nonionic and an amphoteric surface active agent can be arbitrarily used.

Title: Terminal display control device
Inventor: YAMAZAKI KAZUO
IPC: G09G5/40
Filed: 1988-09-21
Abstract: PURPOSE:To prevent the mutual interference of text information and graphics information by storing the position information corresponding to one character of a change text in a control table and plotting only the change test on a bit map plane. CONSTITUTION:The content of a frame buffer 5 is changed if the character information taken out of the frame buffer 5 and the character information to be changed do not coincide. A hardware access routine 7 refers to the control table 6 and plots the content changed by the frame buffer 5 to the position of the bit map plane 9 corresponded by the dissident column CI and dissident character number C2 of the dissident line set with a dissident flag F in the control table 6, thereby allowing the changed content to coincide with the content of the frame buffer 5. The dissident flag is then reset. The mutual interference of the graphics display and the text display is obviated in this way and the change operation is executable regardless of the original display state.

Title: Equipment for multiplex modem
Inventor: ONISHI MAKOTO
IPC: H04J11/00
Filed: 1989-09-14
Abstract: PURPOSE:To attain effective utilization of the frequency by allowing the overlap of modulation spectrums in analog amplitude modulation signals so as to multiplex two modulation waves. CONSTITUTION:A modulation signal A(t) is multiplied with a carrier signal at an angular frequency omega1 at a frequency mixer 1 and both side waves are amplitude-modulated. On the other hand, a modulation signal B(t) is inputted to a frequency mixer 2, in which the signal is multiplied with a carrier signal at an angular frequency omega2, the upper side band is extracted by a high pass filter 3 and the upper side band is amplitude-modulated. The two amplitude modulation waves are added and multiplexed by an adder 4, band-limited by a band pass filter 5 and the result is sent. Since the spectrums of the two amplitude modulation waves are overlapped with each other in this way, the frequency is much more effectively utilized.

Title: Surface treatment of copper member
Inventor: HIRANO SHOEI
IPC: C23C8/12
Filed: 1994-09-30
Abstract: PURPOSE: To suppress the rise of natural potential and to prevent pitting corrosion by forming an oxidized coating film on a copper member by oxidation under heating in an oxygen-contg. atmosphere. CONSTITUTION: A copper member such as a copper tube is heated in an oxygen- contg. atmosphere such as air to form a corrosion resistant oxidized coating film of about 10-500nm thickness on the surface of the copper member. Since this oxidized coating film formed by surface treatment acts as a barrier to electronic conduction, even when an active oxygen producing field is formed, a cathode reaction is not accelerated, the rise of natural potential does not occur and pitting corrosion is prevented.

Filed: 1997-09-02
Abstract: PROBLEM TO BE SOLVED: To solve change of integral dopant concentration of an N<+> buffer layer on a shelf layer which is caused by dopant diffusing outside from a semiconductor substrate.

Title: Input/output control system for external storage
Inventor: MUKAI YUTAKA
IPC: G06F3/06
Filed: 1990-09-07
Abstract: PURPOSE:To improve the transfer speed of the disk data by transferring the disk data in 2n bits through a processor and therefore reducing the access frequency of the processor to a FIFO. CONSTITUTION:When '1' is set to a register 11, a buffer I 9 separates a FIFO-I 3 from a FIFO-II 4. At the same time, a buffer II 10 connects the FIFO-I 3 to the FIFO-II 4 and an FDC 6 stops its operation. In such a constitution, a processor 1 can transfer the disk data in 2n bits. When the disk data are read out, the data are transferred alternately to the FIFO-I3 and the FIFO-II 4 from a DKC 5 in each n/8 byte. Then the data are read out of both FIFOs I3 and II4 via a data line. Thus the transfer speed of data is improved between the processor 1 and a memory 2.
