Title: Cation exchange membrane for alkali metal electrolysis
Inventor: SADA TOSHIKATSU
IPC: C25B13/08
Filed: 1980-06-02
Abstract: PURPOSE: To obtain the titled cation exchange membrane with excellent chemical resistance and oxidation resistance, by forming an electrically neutral layer having a cation exchangeable group and an anion exchangeable group together to a high- molecular membranelike article uniformly and chemically binding a cation exchangeable group and a fluorine atom.  
     CONSTITUTION: A cation exchange resin layer comprises a membranelike article formed from a high-molecular substance finding a cation exchange group and fluorine and, especially, said membranelike article is preferably formed from one binding the fluorine atom to a carbon atom in an α position of a cationic exchange group. To both surfaces or one surface of this cation exchange layer or to an intermediate portion in a sandwichlike manner, one or more of an electrically neutral layer are formed. A ratio of a cation exchangeable group and an anion exchangeable group is in a range of 80:20W20:80 and, as the former, sulfate ester or carboxylic acid group are used and, as the latter, primary, secondery, tertiary amine, quaternary ammonium salt or the like are used. These groups are adhered or impregnated to a surface of a cation exchange membrane to form an electrically neutral layer.

Title: Method of selectively forming thin-film
Inventor: SATO JUNICHI
IPC: H01L21/302
Filed: 1989-03-23
Abstract: PURPOSE:To enhance the selectivity when a thin film is formed selectively by a method wherein a photoetching operation is executed when the film is formed. CONSTITUTION:A photoetching operation is executed when a thin film is formed. By this constitution, an etch rate of the photoetching operation against the thin film inside a hole whose substratum is a semiconductor or a metal becomes slower than an etch rate against the thin film which is grown abnormally outside the hole because light is hard to enter by diffraction the finer the hole becomes. Accordingly, it is possible to remove only the film, which is grown abnormally outside the hole, by the photoetching operation without obstructing that the thin film to be grown inside the hole is grown. Thereby, it is possible to enhance a selective property when the thin film is formed selectively.

Title: Electrode of jet generator using electric field
Inventor: YABE AKIRA
IPC: B01F13/00
Filed: 1986-03-31
Abstract: PURPOSE:To increase the speed of a jet generated from a jet generator using an electric field provided with a hollow electrode by putting an interval of a hollow space of a hollow electrode and a length of a sectional periphery having more than a specific value into a specific relationship. CONSTITUTION:The diameter of a hollow electrode 3 is represented by D, a distance between the center of the hollow electrode 3 and that of a face electrode 2 by 2D (the interval of a hollow space 4 is D), an interval between the hollow electrode 3 and the face electrode 2 by D/2, and a position on the centerline of the hollow space 4, spaced apart from the face electrode 2 by 2D is set as a flow speed measuring position 5. Since the diameter of the hollow electrode 3 is D, the sectional periphery length is Dpi. The relationship between the length of the sectional periphery and the flow speed of the jet resides in that the flow speed increases gradually until the size of D becomes 5mm, and with the size of D being 5mm or more, the flow speed of the jet becomes substantially constant. The flow speed of the jet depends upon the length Dpi of the sectional periphery of the hollow electrode 3, and with Dpi being 15mm or more, the jet effect becomes more remarkable. By this organization, when the sectional periphery length is represented by E, a relationship E>piD, E>15mm is established.

Title: Memory device
Inventor: ONO TOSHIAKI
IPC: G11C11/406
Filed: 1987-03-26
Abstract: PURPOSE:To reduce a sudden change in the load of a power supply at the time of refreshing and to prevent the drop of a power supply voltage by executing refreshing operation at periods different every memory unit, e.g. every memory card, obtained by dividing a memory area. CONSTITUTION:Memory cards 11, 21 are connected to a memory bus 1 and each memory card includes a control circuit 12, identification (ID) information 4 and a dynamic RAM 15. The control circuit 12 reads out the ID information 14 immediately after turning on the power supply, sets up an initial value formed in itself in a refresh counter in a refresh control circuit 17 and then actuates the refresh counter. Since different initial values are set up in each ID information of the memory cards 11, 21, refreshing operation can be executed in different periods in each memory unit. Consequently, the drop of the power supply voltage can be prevented at the time of refreshing operation.

IPC: G11B20/10
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To minimize disappearance of data by transferring and storing a part of data to be recorded into a storage means such as a D-RAM and making a vacant area in the D-RAM at the time of recording the data read out of the D-RAM on a disk by making a read-out speed faster than a transfer speed. SOLUTION: A spindle motor 2 and an optical head 3 are driven to extract a data of TOC(table of contents) information set on the innermost circumferential side of the disk by a system controller 11. The TOC information supplied to a memory controller 12 is stored in a buffer RAM 13 to be used for controlling recording/reproducing operation on the disk 1. Since reading out the data from the buffer RAM 13 is five times faster than writing the data in the buffer RAM, time to spare for reading out the data to the disk 1 is generated during the time of filling up a reduced area in the buffer RAM with the data. User TOC information is updated during this time to spare.

SOLUTION: The voice signal superimposing circuit is provided with a constant voltage control IC 2 that converts voltage received from a power supply into a desired voltage, a smoothing inductor 3 connected to the output terminal of the constant voltage control IC 2, a smoothing capacitor 4, a Schottky diode 5 acting like a feedback path of a load current when a switching transistor(TR) 21 in the constant voltage control IC 2 is turned off. The voice signal superimposing circuit divides output voltage by using detection resistors Ra, Rb, feeding back the divided voltage to the constant voltage control IC 2, comparing the feedback voltage with a reference voltage by a voltage comparator in the constant voltage control IC 2 to control the ON/OFF of the switching TR 21, thereby making the output voltage stable and superimposing a voice signal onto the constant voltage power supply.  Then an output with the voice signal superimposed on the desired power supply voltage is obtained by applying the voice signal to the input terminal of the voltage comparator in the constant voltage control IC 2.
