  • Patent number: 6469606
    Abstract: A coil part which is obtained by sealing at least part of the periphery of a coil with a conductor wound on a bobbin with a high heat-conductive and magnetism-impermeable resin composition, and can efficiently guide out a magnetic flux generated to the outside and efficiently radiate heat generated to the outside.

  • Patent number: 4891492
    Abstract: A tool support mechanism for a robot is adapted for carrying a tool, such as a welding torch. A series of shafts, pulleys and belts cooperate such that upon rotary input, a first arm rotates about a first end thereof with respect to a frame, a second arm rotatably connected at a first end thereof to a second end of the first arm translates but does not rotate with respect to the frame, and a tool support rotatably connected to a second end of the second arm translates but does not rotate with respect to the first arm. The mechanism thus allows a tool to be rotated about an axis spaced from the axis of rotary input.

  • Patent number: 4544826
    Abstract: A method and a device for controlling a welding power supply, employing a control device essentially including a first switch means consisting of at least one switch in element to be turned on and off to control the output current of the power supply, second switch means adapted to be inserted in a welding current attenuating path when the first switch means is in off state, and an impedance means consisting of at least one impedance element connected parallel with the second switch means.

  • Patent number: 4175693
    Abstract: A method for enhancing the reliability of output data from a label reader adapted to read a bar code consisting of a plurality of bars. Each bar in the bar code is scanned at a plurality of points and sets of binary symbols representative of the scanned points along each bar are obtained. Two sums are then formed for each bar, the first being the number of binary "1"s in the set and the second being the number of binary "0"s in the set, and the ratio of two sums is computed. If the ratio is larger than (1+.alpha.) for .alpha.>0, then the data corresponding to the numerator sum is regarded as reliable. If the ratio is less than (1-.beta.) for 0<.beta.<1, then the data corresponding to the denominator sum is regarded as reliable. If the ratio is equal to or larger than (1-.beta.) but equal to or less than (1+.alpha.), then the data is regarded as unreliable.

  • Patent number: 4160901
    Abstract: A coincidence testing method for enhancing the reliability of output data from a label reader adapted to read a bar code consisting of a plurality of bars. Each bar in the bar code is scanned at a plurality of points and sets of binary symbols representative of the scanned points along each bar are obtained. Then the binary symbols in each set are ordered to correspond to the order of the scanned points or segments along each bar. Then coincidence tests are performed on successive pairs of binary symbols in each set to determine whether a reliable decision can be made for each bar.

  • Patent number: 4158435
    Abstract: A method and apparatus for reading label bar codes in which a photoelectric signal representative of an optically scanned bar code label is differentiated. The positive and negative peaks of the differentiated signal are detected, and the time intervals between the peaks are measured by counter means to produce output signals representative of the bar code label. A multi-level threshold comparison technique is used to detect and predict the occurrence of positive and negative peaks.

  • Patent number: 4158834
    Abstract: A data buffer for a label reader system including a data processor. The label reader system includes at least one label reader unit, a first memory means, a second memory means, and a data processor. The first memory means is separately, switchably connected by gate means to a label reading unit, and to the data processor. The second memory means is connected to the data processor. The label reading unit provides a control signal to the gate means so that when data is being transferred between the label reading unit and the first memory means, the data processor then only can transfer data to and from the second memory means. When no data transfer is occurring between the label reading unit and the first memory means, data can then be transferred between and among the first memory means, and second memory means.

  • Patent number: 4019026
    Abstract: A laser beam label reader head of single common axis type wherein light reflection coming from a laser-irradiated label along the axis of a scanning laser beam is diverted by an apertured mirror toward a photoelectric converter. The photoelectric converter is provided with means for removing and blocking incident general light coming from sources other than the laser-irradiated label to preclude influences by ambient light and improve S/N ratio.
