Title: Manufacture of sintered substrate for alkaline battery
Inventor: KIKUOKA TAKAO
IPC: B22F5/00
Filed: 1982-07-30
Abstract: PURPOSE:To improve accuracy of a sintered substrate by maintaining the same position and the constant feeding speed of a porous plate, whereon slurry is to be smeared. CONSTITUTION:A porous plate 1 serving as core material is fed in the shape of a roll 2. 3 denotes a slurry tank filled with slurry 4 produced by kneading carbonyl nickel powder with aqueous solution of binding material. A molding slit 6 of such construction is used that slurry 4 is not applied to a tub terminal forming zone 7 but only to the porous part 8 in about 1mm. thickness. Small holes 10 are drilled at a constant interval in the tub terminal forming zone 7 except the part of the porous plate to be the tub terminal shown by a broken line in such a way that those holes are fitted to the projection parts 11 of the roll 5 provided in the slurry tank 3, thus fixing the position of the porous plate 1. Further, the roll 12 of the guide part is equally provided with the projection parts 11 for fixing the position. The positional accuracy of the porous plate is improved in this way.

Filed: 1995-05-31
Abstract: PURPOSE: To improve the productivity of a thin film transistor, and increase the conductivity of an ion implantation film at a low temperature, by simultaneously performing crystallization and activation of a semiconductor film. CONSTITUTION: On an insulating substrate 1 like glass, an undoped amorphous silicon film, i.e., a-Si film 20 is deposited in an SiH4 -H2 -Ar atmosphere, and then patterned.

Title: Solid electrolyte fuel cell
Inventor: IWAHARA HIRONARI
IPC: H01M8/12
Filed: 1989-05-30
Abstract: PURPOSE:To obtain steady, excellent cell operation characteristics without use of expensive platinum by using nickel in a fuel electrode and LaMnO3 doped with barium in an oxidizing agent electrode in a fuel cell using a BaCeO3 family solid electrolyte. CONSTITUTION:A BaCeO3 family ceramic used as a solid electrolyte has a composition of BaCe1-xMxO3-alpha (wherein M is Nd, La, or Y, 0<=x<=0.15, alpha is 0-0.075) which contains 5-15% Nd, La, or Y in BaCeO3. BaCe0.9 Nd0.1O3-alpha and BaCe0.9Y3-alpha are preferable and the latter is a high temperature type proton conductive oxide and shows the highest conductivity. By using nickel as a fuel electrode, voltage and current density show linear relation and a fuel cell shows steady operation characteristics. The reason why LaMnO3 doped with barium is used as an oxidizing agent electrode is that it has an affinity to the BaCeO3 family solid electrolyte having perovskite crystal structure, and the electrode resistance and polarization resistance are lowered. Its composition is represented by La1-xBaxMnO3-alpha (x<0.15, preferably 0.05<x<0.10, and 0.025<alpha<0.05).

Title: Driving circuit for el element
Inventor: YAMAZAKI HIROSHI
IPC: H05B44/00
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To prolong the life of an EL element and to improve driving efficiency by connecting a capacitor in parallel with a series circuit, supplying a higher harmonic component to the capacitor and thereby passing a low driving frequency with the EL element. SOLUTION: A capacitor 11 is connected in parallel with a series circuit 3 and provided for suppressing the application to an EL element a frequency component higher than the driving frequency of the EL element. A high frequency component is passed by the capacitor 11 to reduce impedance. Thus, a higher harmonic component applied to the EL element is suppressed and an element life is prolonged. Since the higher harmonic component is passed by the capacitor 11, a serial resonance frequency is coincided with the driving frequency of the EL element. That is, by coinciding the serial resonance frequency with the driving frequency, the EL element is driven with high efficiency. Also, the reduced impedance of the higher harmonic side contributes to high efficiency.

IPC: H03K17/78
Filed: 1986-06-11
Abstract: PURPOSE:To stop the flowing of a workpiece by checking the time interval of the input signal of a sensor, considering that the input signal after the time- over is unfair and neglecting the input signal, at an automated plant. CONSTITUTION:By an input signal accompanying the detection of a photo- interrupter 1, two timers 4 and 5 are sequentially operated through a photo- coupler 2.

Other timer 5 has a function to set the time to operate so that the input signal after the time-over cannot be temporarily outputted. To the input of the signal in which the time-over is not executed, the output is executed through an output transistor 9 to a signal processing device 10 as it is, and as such, a logic circuit composed of a NAND gate 7, etc., is constituted. Thus, since the flow of the workpiece is temporarily stopped, the processing accuracy of the workpiece is stabilized.
