Title: Manufacture of battery electrode
Inventor: INOUE TOSHIHIKO
IPC: H01M4/139
Filed: 1997-11-13
Abstract: PROBLEM TO BE SOLVED: To restrain cracks due to solvent scattering or internal stress and facilitate membrane thickness control by powdering a mixed material with fluid properties including an active substance and a bonding agent by spray dryer means, and integrally molding a produced power with a current collector by hot press means to form an electrode. SOLUTION: As spray dryer means, for example, a mixed material with fluid properties including an active substance and a bonding agent is sprayed toward hot gas such as hot air, and thereby powder is dried at a high speed by heating of the hot gas. As a typical bonding agent, a polyvinylidene fluoride having its thermal fusion properties is exemplified. The temperature in hot press is more than a melting point of the bonding agent or near the melting point. Thereby, re-arrangement due to flow of the bonding agent in the hot press is made possible, reduction of a void in a laminate membrane formed at the current collector can be ensured, make it more advantageous to reduce crack in the laminate membrane and reduction in internal stress.

Title: Analog-to-digital converting device
Inventor: YAMADA TOSHIYUKI
IPC: G06G7/22
Filed: 1988-12-10
Abstract: PURPOSE:To decide whether or not a synchronizing signal is normal in real time during D/A conversion by comparing the addition signal of the outputs of a cosine and a sine multiplier with the multiplication signal of two signals of a quadrant selecting circuit and a carrier signal. CONSTITUTION:The A/D converting device which is constituted as specified processes the outputs of the cosine multiplier 3 and sine multiplier 4 by a subtracter 5 to obtain an output (a)=Ksin(theta-4)sinomegat and when sin(theta-4) is nearly equal to 0, the A/D conversion is normal. The output b=Ksinomegat.sin(theta+4) of an adder 9 and the output (c)=K.sinomegat.sin2theta of a multiplier 10 are obtained. When the D/A conversion is normal, theta is nearly equal to 4, so (b) is nearly equal to Ksinomegat.sin2theta and the output (d) of a comparator 11 has an error smaller than a specific value; and '1' is therefore outputted to indicate that the conversion is normal. If abnormality occurs, sin(theta+4) is not equal to sin2theta, the difference between the input signals (c) and (b) of the comparator 11 exceeds the specific value, and '0' is outputted to indicate the abnormality. Thus, the three-phase synchronizing signal is A/D-converted to decide whether or not the conversion is normal in real time.
