Title: Image forming device
Inventor: OSUMI KIYOTAKA
IPC: H04N1/12
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To enhance the accuracy of an image forming position on a transfer material by controlling an original image forming position on an image carrier, with a detection signal by a detecting means. SOLUTION: Various kinds of paper sheets are different in a butting way against the nipping part of a resist roller, so that top end margins have dispersion. Further, in the paper of the same kind as well, the ON timing of the resist roller has the dispersion because of the engagement of a gear, a difference in the response time of a clutch, etc. For preventing a deviation in the image forming position on the paper caused by the above dispersion in a carrying direction and a direction perpendicular to it, a linear sensor 50 for detecting the edge of the paper is provided before a transfer process. Then, the top, left and right edges of the paper are detected by the linear sensor 50 (200).  The timing of writing with a laser on a photoreceptor drum in the carrying direction of the paper and the perpendicular direction is decided with the obtained data (201) and then, fed back to a laser driver 202, to attain writing on a photoreceptor.

Title: Mono-block type sealed lead-acid battery
Inventor: HAYASHI TOSHIAKI
IPC: H01M50/529
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To provide an inter-cellar connection part having high reliability in particular by providing a spacer with a recessed part or a continuous or intermittent rib along the outline of a plate so that the plate is fitted in a surface, which abuts on the plate. SOLUTION: A spacer 6 is provided with a recessed part 7 in a surface, which abuts on a plate, so as to fit to the outline of a plate. Depth of the recessed part 7 is formed smaller than the thickness of the plate at an end of a plate group so as to prevent the generation of hindrance of a contact with a glass separator. Consequently, when the spacer 6 abuts on the plate at the end of the plate group for insertion, the spacer can be easily inserted in the vertical direction. Since the plate and the inner surface of a battery jar do not directly contact with each other, scraping of the active material and intrusion of the active material into an inter-cell connecting hole can be prevented. After the insertion, positional displacement of the inter-cellular connecting hole from an inter-cell connecting button, which is welded to an upper part of the plate group, is remarkably improved.

Title: Rotary transformer and manufacture thereof
Inventor: IGUCHI TETSUYA
IPC: H01F1/37
Filed: 1992-12-25
Abstract: PURPOSE:To obtain a rotary transformer including a high precision core having a large number of grooves, by molding at least one of first and second cores out of a polymeric material in which magnetic particles are dispersed. CONSTITUTION:To form a stationary core 2S, injection molding is performed using a polymeric material in which magnetic particles are dispersed, for instance, a ferrite core. In the stationary core 2S using a ferrite resin, deformation such as warpage due to the molding hardly occurs since the ferrite resin is excellent in moldability. Thus, a core having a large number of grooves for multichannels can be manufactured easily and with high precision. Further, the original core having a large number of grooves, which is obtained by injection molding, can be cut and divided into a predetermined number of grooves, thereby to manufacture a plurality of cores having a particular number of grooves. Accordingly, a rotary transformer can be obtained which includes a high precision core having a large number of grooves.
