Title: Plasma display device
Inventor: KOBAYASHI YOSHIHIKO
IPC: G09G3/282
Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To suppress malfunctions due to discharge currents of auxiliary anodes in a plasma display device. SOLUTION: A current IDC is made to flow from an auxiliary anode driving circuit 12 through a discharge path DC ranging from a resistor 14j , an auxiliary anode 12j , an auxiliary cell 5mj and a cathode 3m to a cathode driving circuit 13m by the auxiliary discharge of the auxiliary 5mj . However, since the magnitude of the current IDC is suppressed by the resistor 14j , an interference with respect to the display anode parallel arranged adjacently to the auxiliary anode 2j is reduced. Thus, the effect on an anode driving circuit by the current IDC is extinguished and malfunctions in a display are suppressed.

Title: Mask for x-ray exposure and manufacture thereof
Inventor: IBA YOSHIHISA
IPC: G03F1/22
Filed: 1998-06-15
Abstract: PROBLEM TO BE SOLVED: To prepare a membrane simply and easily without increasing the number of processes, and to improve the yield of a mask while enhancing the performance of the mask, by continuously forming a high stress section and a low stress section in the membrane without extraction to the outside of a film forming device. SOLUTION: A pattern is drawn and developed to an electron beam resist film 15 by using electron beams. An X absorber 13 consisting of Ta is etched while using the electron beam resist film 15 as a mask and patterned by applying a dry etching method employing chlorine gas as an etching-gas. The electron beam resist film 15 is removed by dipping in a resist release liquid, and the mask for X-ray exposure is completed. Since tensile stress in an SiC film 12 is hardly changed even when the SiC film 12 is overetched when the X-ray absorber 13 is etched, no distortion is generated in the mask, and the SiC film 12 is not also crumpled naturally.

IPC: H01L21/82
Filed: 1990-06-25
Abstract: PURPOSE:To enable pins to be selected so as to lessen wirings in intersection at rough wiring and to decrease a wiring region between blocks in area by a method wherein a function through which wirings led out from a block are provided to the same side of the block is provided for each net. CONSTITUTION:A function through which wirings 3 led out from a block 1 are provided to the same side of the block 1 is provided for each net. For instance, the wirings 3 inside the block 1 led out from a standard cell row 2 to an interblock wiring region 4 are laid as shown in a Figure for each net. By this setup, as wirings are increased in number of paths at interblock wiring, the paths can be selected so as to prevent intersections from occurring in the wirings at rough wiring. Therefore, an interblock wiring region can be lessened in area, so that an LSI chip can be decreased in area.

Abstract: PROBLEM TO BE SOLVED: To prevent a shift in lateral bias, a drop in output, and a secular change by making a magnetic field produced with a longitudinal bias not substantially enter an antiferromagnetic layer or a magnetic layer whose magnetism is fixed by the antiferromagnetic layer. SOLUTION: On a substrate 10, the antiferromagnetic layer 11 which fixes the magnetism of ferromagnetic layers 12 and 13, a nonmagnetic layer 14, and a soft magnetic layer 15 are formed. Further, soft magnetic layers 17 and 17' and electrode layers 18 and 18' which serve as a longitudinal bias pattern in another process are formed.

Title: Hot water storage tank of water heater utilizing solar heat
Inventor: KOSHIJIMA JIROU
IPC: F24J2/46
Filed: 1980-11-27
Abstract: PURPOSE: To prevent the heat radiation of stored hot water and enhance the heat collecting efficiency by a method wherein the hot water storage tank is made of double tube type structure.  
     CONSTITUTION: The hot water heated by the solar heat collected with a collector is led from a inlet port 3 in an inner tank 1 to till the inner tank first of all and, after that, flows out from an exit pipe 5 open at the bottom of the inner tank 1 to fill an outer tank 2 and finally exits from an outlet port 6 provided at the bottom of the outer tank 2. At that time, the high temperature water in any of the both inner and outer tanks 1 and 2 is accumulated in the upper part of every tank. In such a manner as described above, the hot water is circulated between the collector and the storage tank to become hotter and hotter. During the process of the water becoming hotter, the hot water, the temperature of which is the lowest in the inner and outer tanks, enters in the collector and is heated by means of the collector and then enters in the upper part of the inner tank 1. Accordingly, because the most high temperature part of the hot water is stored in the inner tank 1, the heat radiation from the stored hot water is avoided with a small amount and the remarkably good heat collecting efficiency is resulted.
