  • Patent number: 5115306
    Abstract: A projection cathode-ray tube for a projection video apparatus, comprising a green-emitting screen including a terbium-activated lanthanum oxychloride phosphor. The disclosed phosphor exhibits a luminance maximum at a minimum beam size, a property advantageous for producing a high-resolution image. The phosphor is chemically stable at high temperatures. The phosphor shows no substantial decrease in emission efficiency even at about 80.degree. C., and the emission luminance is twofold that of the prior art. The green-emitting screen is made by the steps of: (a) settling the terbium-activated lanthanum oxychloride phosphor onto the inner surface of a cathode-ray tube, wherein the phosphor is settled from a suspension comprising a solution of potassium water glass and barium nitrate, and wherein the ratio of the weight concentration of potassium water glass to barium nitrate is in the range between about 20 to about 35; and (b) removing the resulting supernatant.

  • Patent number: 5029071
    Abstract: A multiple data processing system includes first and second microprocessors for executing the same data processing in parallel fashion. A selector selectively delivers one of the output data of the microprocessors to an external I/O device. A comparator detects an off normal data processing state by comparing the output data of the first microprocessor with the output data of the second microprocessor. An operation monitor evaluates the operation state of the microprocessors in response to a signal from the comparator and instructs the selector to deliver output data sent from a normal channel to the external I/O device.

  • Patent number: 5009527
    Abstract: A thermal transfer color printer for printing color images on individual sheets of paper. One sheet of paper at a time is removed from a stack of paper stored in a cassette and this sheet is transported by a reversible platen roller in a first or forward direction at a first predetermined rate. While the sheet of paper is gripped between the reversible platen roller and one or more pinch rollers, slack is removed by a slack removing device. A multicolored ink ribbon with successively arranged color segments also is transported in the first direction at the same predetermined rate. A thermal printhead presses against the reversible platen roller to press the ink ribbon and sheet of paper together as they move in the first direction. Energization of the thermal elements on the thermal printhead by color component signals corresponding to the current color of the ink ribbon causes the particular current color to be thermally and selectively transferred to the sheet of paper.

  • Patent number: 4998164
    Abstract: A color image sensing system includes a CCD image sensor with an optical color filter. A CCD driver is provided to electrically drive the image sensor, which is attached to a vibration table serving as a swing-driver for moving the image sensor along a horizontal direction such that each cell of the image sensor shifts, in a frame period including first and second field periods, between four different sampling positions substantially aligned in the horizontal direction. During each field period, each cell is positioned at two sampling positions, wherein a brightness signal component is produced at one sampling position and color signal components are produced at these sampling positions. The distance between two sampling positions at which the brightness signal components of the first and second field images are produced is set to be half the horizontal pitch of the cells of the image sensor.
