Inventor: KOURA NOBUYUKI
IPC: H01M10/0568
Filed: 1987-10-06
Abstract: PURPOSE:To make it possible to use metals such as lithium, calcium, magnesium, zinc, iron, etc., or these alloy as a negative electrode for a secondary battery by using mixed molten salt consisting of alkylpyridiumchlorid and various kinds of metal halides as electrolyte. CONSTITUTION:Mixed molten salt consisting of alkylpyridium halides (alkyl group: C1-C5; halogen: Cl, Br, I) of 20-80mol% and each one or two kinds of various kinds of metal halides MXn (M=K, Ca, Li, Al, Ca, Mg, Zn, Fe; X: Cl, Br, I; n: 1, 2, 3) is used as electrolyte. Hereby, it becomes possible to use, as a negative electrode material for the second battery, materials which are not so sufficiently put into practical use yet as a negative electrode material for a secondary battery, such as lithium, calcium, magnesium, zinc, and iron or these alloy, etc. And since it is molten salt, it is higher in conductivity than the electrolyte in organic line, thus a secondary battery having high output can be realized.

IPC: G02F1/13
Filed: 1992-09-21
Abstract: PURPOSE:To increase the temp. rising rate of upper and lower glass substrates and to improve throughput in the process of forming a gap between two substrates for a liquid crystal display element. CONSTITUTION:Upper and lower glass substrates 4, 5 of a liquid crystal display element are heated with a heater block 1.

Title: Remote monitor control system
Inventor: OKAMOTO ATSUSHI
IPC: H04Q9/00
Filed: 1991-09-30
Abstract: PURPOSE:To prevent overshoot of a return current caused when the polarity of an output voltage of a power supply section is inverted by supplying the return current in response to the capability of supplied power from a rectifier circuit. CONSTITUTION:When a return current is supplied to a transmission line 12, a processing section 21 applies OFF control to a transistor (TR) Q3, and when no return current is supplied, the processing section 21 applies ON control to the TR Q3. When the TR Q3 is subject to OFF control, since a voltage of +24V is applied to a connecting point C, a Zener diode ZD2 is broken down in the reverse direction and a potential at the connecting point C is decreased to 5V. Thus, a prescribed current as a return current A is supplied. When the return current is supplied, the polarity of an output voltage of a power supply section is inverted and after the output voltage crosses with OV, the potential at the connecting point C gradually rises. Thus, the return current increase gradually and the occurrence of overshoot is not caused different from a conventional system.

Title: Production of atomized iron powder or steel powder
Inventor: YAMANE YASUSHI
IPC: B22F9/08
Filed: 1984-11-28
Abstract: PURPOSE:To produce atomized iron powder having a high quality by refining a molten metal consisting essentially of iron in the presence of basic reduced slag, receiving the molten metal into a tundish without adding a force deoxidizing agent thereto and specifying the temp. thereof. CONSTITUTION:Oxidized slag is discharged from the molten metal which is produced in a melting furnace and consists essentially of iron and while the molten metal is held at <=1,680 deg.C, a slag forming agent consisting of CaO- CaF2-CaSi is added thereto and the molten metal is refined in the presence of the basic reduced slag. The molten metal maintained at <=1,680 deg.C is then tapped into a ladle 3 without using a deoxidizing agent at all. The molten metal in a protecting gas is tapped from the ladle 3 into the tundish 2 while the molten metal is held shut off from the atm. by a shutting means 4. The molten metal is thus made to 1,620 deg.C temp. and <=55ppm oxygen content. The atomized iron powder or steel powder having the high grade is produced without closing the nozzle.

IPC: H01L21/339
Filed: 1996-09-24
Abstract: PROBLEM TO BE SOLVED: To provide a CCD image sensor outputting a blooming-suppressed high-resolution sequential color image signal and a clocking system. SOLUTION: When an image is irradiated from the back through a shutter- synchronized rotary three color sequential filter, photoelectrons e<-> produced in an active layer near the back are focused between potential barrier structures (P-wells) via a depletion layer. 7 gates electrodes 310 are provided for each P-well and photoelectrons at an approximately square pixel region one side of which is equal to the width thereof form a charge packet 314 below the electrodes 310. The package is shifted in the layer of a CCD structure 304 sequentially by a 7-phase ripple clock voltage applied to the electrodes 310. The pixel regions are separated by boundary channels in parallel to this shift to suppress the blooming whereby three charge packets form 3-color image signals sequentially at one pixel regions to obtain a high resolution.

Thus, the system construc tion and the adjustment at the time of operation can be simplified and facilitat ed.
