Abstract: PURPOSE:To miniaturize the overall structure and prevent wear or breakage of each part in a driving wheel of an unmanned carrying vehicle by providing a driving motor and a speed reducer to the inside of the wheel and supporting the driving motor via a bearing. CONSTITUTION:Driving force of a driving motor 5, which is installed inside a wheel 11, is transferred in turn from a gear 6 to a gear 7 and from a gear 8, which is on the same shaft as for the gear 7, to a gear 9, all of which form a speed reducer part, so that the wheel 11 is rotated via a wheel hub 10, which is connected to the gear 9. The driving motor 5 is connected to a motor base 14, which is installed to a plate 19. In addition, the tip of the gear 6 is supported by a bearing 15. In addition, the driving motor 5 is supported by a bearing 16 via the motor base, which is located between the motor 5 and the motor hub 10. With this contrivance, the allover structure of the driving wheel can be made compact, and problems of fluctuation of assembling accuracy can be solved. At the same time, wear of the gears 6 to 9 or breakage of the driving motor can be prevented.

Title: Printer
Inventor: YAMANE TOSHIYUKI
IPC: B65H7/06
Filed: 1998-01-23
Abstract: PROBLEM TO BE SOLVED: To detect jamming of a paper immediately after, the conveyed paper has been jammed. SOLUTION: This printer comprises a carriage which is moved to be scanned in a constant speed along a conveying width direction of a conveyed paper and performs printing on the paper by means of a print head provided of the carriage. While the carriage is moved to be scanned after starting the printing operation, a CPU calculates a moving speed of the carriage based on a pulse signal (S4). The CPU judges whether or not the calculated moving speed of the carriage is lower than a predetermined speed (S5). When it is judged that the moving speed of the carriage is lower than the predetermined speed (S5: YES), the CPU detects paper jamming by judging that the jamming of the conveyed paper has occurred, then the CPU stops the conveying operation of the paper and the printing operation (S6).

Title: Buffer for holding monolithic catalyst carrier
Inventor: YAGI TOSHIROU
IPC: F01N3/28
Filed: 1981-01-29
Abstract: PURPOSE:To securely hold a catalyst carrier for a long period, by making a buffer of stainless steel whose inner part is an austenite layer and whose outer part is a ferrite layer and by providing the buffer in the exhaust line of an engine. CONSTITUTION:To elastically hold a monolithic catalyst 4 in a casing 1, a wave- shaped net or sheet of stainless steel is provided. The inner part 7a of the stainless steel net or sheet is a thick austenite layer. The outer layer 7b of the net or sheet is a thin ferrite layer. Since the thermal expansion coefficient and thickness of the inner layer 7a are higher than those of the outer layer 7b, the inner layer expands beyond the elastic limit of the outer layer at high temperature so that the net or sheet of stainless steel remains expanded from the initial size when it is cooled. For that reason, the carrier for the catalyst 4 is securely held even if the temperature is low.
