Title: Electrophoretic apparatus
Inventor: MIKAMI SADAO
IPC: G01N27/447
Filed: 1986-09-24
Abstract: PURPOSE:To eliminate the generation of a gas of hydrogen, oxygen or the like and pollution of an migration liquid, by providing as anode diaphragm a cation selectively permeating ion exchange film, with a smaller ion exchange capacity or with an anion selectively permeating ion exchange film formed on the anode side. CONSTITUTION:When an anode 5' uses metal Fe with the base potential lower than an oxygen generation potential 5', no oxygen is generated as a current flows in Fe Fe<2+>+2e<->. When a cathode 6' uses AgCl as reduction type elec trode generating no hydrogen and hence, no hydrogen is generated. In an anode diaphragm 7', F2<2+> is blocked and univalent ion such as K<+> and H<+> are allowed to permeate selectively. Then, in a cathode 8', ion component such as K<+> and TEA<+> (triethanolamine) in a migration liquid is allowed to permeate whereas anion Cl<-> as a part of an cathode liquid is allowed to permeate into the migra tion liquid. In the end, an electrode ion dissolved is blocked from permeating into a migration chamber 2 by the ion selectively permeating film thereby preventing pollution of the migration liquid.

IPC: H04L69/40
Filed: 1992-08-25
Abstract: PURPOSE:To supervise and control an optical signal amplifier (repeater) which disables the supervision and control by the generation of any fault between an optical signal terminating device (LTM) and LTM, in an optical transmission line network composed of the repeater, and repeater supervisor and controller (CONT) for supervising and controlling the LTM and the repeater. CONSTITUTION:When any fault is generated between an LTM 1 and LTM 2, each LTM detects the generation of the fault, addresses are autonomously changed so as to handle the LTM 1 and the repeater enabling normal communication with the LTM 1 as one sub net and to handle the LTM 2 and the repeater enabling normal communication with the LTM 2 as the other sub net. Since such a change is autonomously performed, a packet can be transferred to the destination by sending the packet to the two difference sub-nets in the case of supervising and controlling the repeater from the CONT.

IPC: H02J17/00
Filed: 1984-10-25
Abstract: PURPOSE:To obtain an electromagnetic converting transformer for thin electronic equipment with good transfer characteristics of a signal and an electric power by positioning the thin magnetic substance of the central part of the secondary coil to the clearance of the core of an external device and forming a closed magnetic path. CONSTITUTION:The electromagnetic converting transformer 10 has the core 1 composed of a magnetic material having partially the clearance G equal to or a little larger than the thickness of a card-shaped thin electronic equipment. The primary coil 2 is formed by approaching to the facing surface of the core 1 forming the clearance G as much as possible and by winding a pair of sheet-shaped coils 2a and (b) so that it can be in paralled to the facing surface. This is composed of the secondary coil part 5 which consists of the sheet-shaped secondary coil 3 laid under the thin electronic equipment and a thin magnetic substance 4 located at the central part of a secondary coil 3. While the thin electronic equipment is linked with the external device, the thin magnetic substance 4 is located at the clearance of the core 1 and forms a closed magnetic path, and therefore, the electromagnetic converting transformer with good characteristics that the leakage flux is little and the attenuating quantity is little, can be obtained.

Title: Electromagnetic wave shielding transparent substrate
Inventor: GOTO HIDEKI
IPC: H05K9/00
Filed: 1998-08-10
Abstract: PROBLEM TO BE SOLVED: To obtain transparency and increase in electromagnetic wave shielding effect by depositing an adhesive layer, a transparent conductive film and a metal thin-film layer in this order, as necessary on at least one face of a transparent high molecular film and then removing only the metal thin film layer by selective etching to form a filter pattern. SOLUTION: A high molecular film in a transparent high molecular film as a base is made of thermoplastic resin, ultraviolet curing resin, thermosetting resin or the like. And, it has a transparency of 80% (50% as a final product) or higher than light transmissivity at 550 nm wavelength. When fabricating a substrate by depositing copper as a metal layer on a transparent high molecular film, a transparent metal oxide is formed as an adhesive layer to obtain both transparency and adhesion. In patterning copper, if it is a transparent conducive film of a high crystallinity, only a copper layer is selectively etched using a selective etchant such as a secondary iron nitrate. Thereby, superior durability as well as high shielding property can be obtained.

Title: Image display device and its drive method
Inventor: AKIMOTO HAJIME
IPC: G09G3/20
Filed: 1997-08-22
Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption of a scanning by superimposing and applying a drive voltage, which is used to drive one of the scan lines while conducting at least one of the row and column direction scannings, in the falling portion of the drive voltage, which is used to drive the scan line that proceeds the scan line above. SOLUTION: When the scanning by an input switch scan line 7 is completed, a gate line control line 20 is turned on for a certain period. At that time, gate lines 3a and 3b are electrically connected, and their voltages become VA. The voltage VA is the middle value of the maximum applied voltage and the minimum applied voltage of a gate line 3. Then, the line 20 is turned off. At that time, the voltage of the line 3a is lowered to an off-level, and the voltage of the line 3b is increased to an on-level. This operation is successively repeated. The line 3b does not consume drive power, the voltage of the line 3b is increased to the voltage VA, which is the middle value between the maximum applied voltage and the minimum applied voltage, so that what is required is only the driving equivalent to the residual half voltage.
