Title: Rewritable bar code display body, method and device for its processing, and bar code read method
Inventor: HOTTA YOSHIHIKO
IPC: G06K1/12
Filed: 1991-06-19
Abstract: PURPOSE:To obtain bar code display which is very vivid on the boundaries between bar code pictures and ground parts and is superior in durability and to present a rewritable display body and its processing method and device. CONSTITUTION:A printing system, thermosensitive paper, a heat transfer ribbon, or the like is used to show the conventional bar code display. It cannot be rewritten. The bar code display formed by the printing system has a fault of a high cost though being vivid. The bar code display formed with thermosensitive paper and the heat transfer ribbon is not sharp on boundaries between bar pictures and the other ground parts to cause a read error sometimes. With respect to this bar code display body, a thermosensitive recording layer 12 whose transparency is reversibly changed by temperature is provided on a supporting body 11 directly or with a reflection layer or a coloring layer 14 between them. It is preferable that the reversible thermosensitive recording layer 12 is made of materials where organic low polymer matters are dispersed in a resin base matter.

Title: Highly flexible and highly electromagnetic shielding cable
Inventor: WATANABE YASUHIRO
IPC: H01B11/06
Filed: 1993-07-15
Abstract: PURPOSE:To enhance flexibility and electromagnetic shielding property by winding an nonadhesive insulating tape on a wire bundle, and applying a cover formed by braiding metal fine lines thereto. CONSTITUTION:An nonadhesive insulating tape 2 is wound on a wire bundle 1 with 1/2 superposition. The tape 2 has a metal particle evaporated layer between nonadhesive insulating layers. A cover 3a formed by braiding stranded wires consisting of a plurality of stranded metal fine lines more slender than conventional ones is provided on the tape 2. Flexibility is enhanced because the mutual tapes 2 and the tape 2 and the wire bundle 2 are never adhered to each other. Since the metal particle evaporated layer is provided between the nonadhesive insulating layers in the tape 2, and the set number of stranded wires is increased to minimize the clearance of mesh, EM shielding property is improved.

Abstract: PURPOSE:To avoid an artificial error of measurement and to eliminate the movement of an object to be measured owing to vibrations, etc. generated during the measurement by mechanizing a universal projector by means of a photoelectric scanner and a video monitor. CONSTITUTION:An overall photoelectric scanner 7 reads the whole of an object 1 to be measured and projects an entire image of the object 1 to an overall video monitor 12. Furthermore the terminal parts of measurement are indicated by means of crucial marks 37, 38, etc., and the distance is calculated by a central processor 24 between the measuring terminal part and a reference point, i.e. the intersecting point of horizontal and vertical bright lines 32 and 35. At the same time, only the measuring terminal part is read by a magnifying photoelectric scanner 8. The (x)-(z) tables 9-11 can be automatically moved so that the point of measurement is formed an image at the center of screen of a magnified video monitor 14. At the same time, both scanners 7 and 8 are connected fixedly to the tables 9-11 and moved. Thus, the movement of the object 1 on a table 2 is eliminated. The size of the object 1 can be measured with indications of the crucial marks when the object 1 is projected within a 1/4 area of the monitor 12.

Filed: 1982-10-05
Abstract: PURPOSE:To reduce the number of parts and the cost and to simplify assembling by forming a regulating part, which regulates the movement of a driving ring, and a pressing part, which presses the ring in the direction of the optical axis, in a turning barrel as one body. CONSTITUTION:A fixed pawl 2b which regulates the movement of a zoom gear 10 as the driving ring and a pressing pawl 2c which presses the gear 10 in the direction of the optical axis are formed with a resin together with a turning barrel 2 as one body and can be deformed elastically in directions of arrows B and B' and arrows C and C' respectively. The gear 10 is inserted and set easily from the right of the barrel 2, and its movement is regulated by the pawl 2b. In this state, the pressing pawl 2c presses always the gear 10, and therefore, the rotatory force of the gear 10 is transmitted to the barrel 2 by the frictional force between the gear 10 and the pawl 2c. Thus, parts which are provided independently of the barrel conventionally are formed together with the barrel as one body to reduce the number of parts and the cost, and assembling is simplified.

Filed: 1989-07-07
Abstract: PURPOSE:To simultaneously transfer the same data to plural lower rank agents from a higher rank agent by setting simultaneously the bus using enabling signals to the lower rank agents which are designated by an internal bus mediation mode register. CONSTITUTION:A processor 1 sets bits 0 and 1 of an internal bus mediation mode register 5 at '1'. Then the processor 1 starts the DMA control parts of both lower rank agents A6 and B7 and sets the bus request signal lines A9 and B10 respectively. An internal bus control means 4 confirms that both lines A9 and B10 are set and set simultaneously the bus using enabling signals A12 and B13 when both bits 0 and 1 of the register 5 are kept at '1'. Thus both agents A6 and B7 start the DMA transfer at one time. As a result, a higher rank agent 2 can transfer the same data to both agents A6 and B7.
