Title: Solid electrolyte and fully solid lithium cell using the same
Inventor: FUJINO MAKOTO
IPC: H01M10/05
Filed: 1996-05-10
Abstract: PROBLEM TO BE SOLVED: To obtain a solid electrolyte having high ion conductivity consisting essentially of Li2 S-SiS2 by specifying the total percentage content of OH groups included in Li2 S and SiS2 as the source material. SOLUTION: The total percentage content of OH groups included in Li2 S and SiS2 as the source material is controlled to <=500ppm, preferably <=100ppm. Namely, when the OH groups are included in Li2 S and SiS2 , a part of SLi bonds changes into OLi bonds in the synthesis of a solid electrolyte. When the amt. of OH group in the source material increases, the proportion of OLi bonds in the solid electrolyte also increases. Since the Coulomb force between -O<-> and Li<+> is larger than the force between S<-> and Li<+> , Li<+> which contributes to the ion conductivity of the solid electrolyte is firmly bonded to the glass skeleton and hardly diffused. Therefore, with a larger amt. of OLi bonds, the ion conductivity of the solid electrolyte decreases.

Title: Image analyzer
Inventor: OKAMOTO YUUZOU
IPC: G01B11/02
Filed: 1978-09-21
Abstract: PURPOSE: To provide an image analyzer prevented from wrong measurement, by regarding a body as one piece when data on the presence of the body are simultaneously and continuously present in the registers of the rows and columns of an L-shaped body detection circuit.  
     CONSTITUTION: The body 1 is visually detected by a photoelectric converter 2 and scanned along a prescribed width in directions X, Y. Each picture element is converted into a digital value by an A-D converter 3 depending on the density. The digital value is changed into a binary code by a circuit 4. The body part is represented as "1". The blank part is represented as "0". The bindary code is supplied to a binary-coded image register 5 and then applied to a diameter measuring circuit 6. It is judged whether or not data are continuous in coordinate positions on a diagonal. It is also judged whether or not data are continuous in coordinate positions on another diagonal perpendicular to the former. When these data are continuous, the body is regarded as one piece. Such bodies are divided into groups with regard to their diameter and the number of the bodies of each group is counted. As a result, wrong measurement likely to take place when there are a plurality of bodies is prevented. The number of the bodies of equal diameter is thus accurately measured.

CONSTITUTION:When the in-room flag of the user is not '0', it is discriminated whether the user is in the room for more than the prescribed time (24 hours) or not and it is regarded that the user leaves the room without reading the card of the user itself. Then, the in-room flag of the user is reset to '0' for an anti-pass back check. As a result to temporarily unlock an electric lock 21, a managing person can turn a knob and go into the room. Then, based on a detection signal caused by a door open detecting sensor 4 according to the open of a door 2, the in-room flag of the user is set to '1'. From such a time point, it is started based on a timer 3d to count a time during which the user is in the room. Thus, even when the user leaves the room without executing the ID identification of the time of leaving, the user can go into the room again and the anti-pass back check can be functionally and really operated.
