  • Publication number: 20170094071
    Abstract: A moving amount detector that sets a movable member included in a device of a mounting destination or an object conveyed by the device as a detection target and detects a moving amount of the detection target includes: an imaging unit that repeatedly captures images of the detection target at a constant sampling period while the detection target moves; and a moving amount calculating unit that selects two images to be compared with each other among a series of images of the detection target captured by the imaging unit such that an imaging time difference between the two images is increased as a difference due to moving of the detection target is further generated between the two images and calculates a moving amount of the detection target based on the difference.

  • Publication number: 20160194168
    Abstract: A multi-feed detection apparatus for detecting multi-feed of a sheet conveyed along a paper path is provided. The apparatus includes a first movement amount sensor disposed on the paper path to face a first surface of the sheet to detect a movement amount of the sheet; a second movement amount sensor disposed, on the paper path, in a position at which the first movement amount sensor is disposed to face a second surface of the sheet to detect a movement amount of the sheet; and a determination portion configured to determine that a conveyance state of the sheet is multi-feed when a difference between the movement amount of the sheet detected by the first movement amount sensor and the movement amount of the sheet detected by the second movement amount sensor is equal to or greater than a threshold.

  • Patent number: 7675738
    Abstract: A gas insulated switchgear has: circuit breakers, circuit breaker vessels, first disconnector and maintenance earthning switches connected to first bus bars connected to circuit breaker vessels and also to main bus bars, second disconnector and maintenance earthning switches connected to second bus bars connected to the circuit breaker vessels, circuit breaker operating mechanisms, first and second disconnector and maintenance earthning switch operating mechanisms, and first and second disconnector and maintenance earthning switch operation links for linking the disconnector and maintenance earthning switches and the operating mechanisms for three phases. The second disconnector and maintenance earthning switch operation links are arranged so as to pass through inter-phases of the first bus bars and the operating panels of the circuit breaker operating mechanism and the first and second disconnector and maintenance earthning switch operating mechanisms of each phase are arranged on a common flat plane.

  • Patent number: 7515398
    Abstract: In a one-and-a-half circuit breaker system gas-insulated switchgear assembly for three-phase AC transmission, the circuit breakers are located on a common horizontal floor directed in Y direction. First main bus bars extending in X direction are located above the first circuit breakers. The positions of the first main bus bars in different phases are different from one another only in height. Similarly, the second main bus bars extending in X direction are located above the third circuit breakers. Each phase of the main bus bars and disconnecting switches is located in a common horizontal plane. The heights are different for different phases. Relative locations of the disconnecting switches are substantially common for every phase horizontally, but are shifted in the X direction.

  • Patent number: 4985914
    Abstract: In a voice storage and retrievel system, a controller generates a series of start-point addresses and a series of end-point addresses from a dialled signal sent from a registered subscriber station. The start-point addresses are sequentially stored into a first FIFO and the end-point addresses are successively stored into a second FIFO. The output of the first FIFO is successively supplied as an initial count value to an address generator whose output is connected to a comparator as well as to a voice segment memory, the output of the second FIFO being supplied to the comparator as a reference value. The address generator increments its output beginning with each successive initial value to read voice segments from the voice segment memory for transfer to a line buffer coupled to the subscriber station.
