  • Patent number: 9507197
    Abstract: A lighting device includes: a light guide plate; a light source; and a light modulation element disposed on a surface of or in the inside of the light guide plate, and adhered to the light guide plate. The light modulation element has a pair of transparent substrates, a first electrode provided on a surface of one of the transparent substrates, a second electrode provided on a surface of the other of the transparent substrates, and a light modulation layer, provided in a gap between the transparent substrates, exhibiting a light-scattering property or a light-transmitting property concerning light from the light source depending on intensity of an electric field. One or both of the first and second electrodes include partial electrodes. First partial electrodes of the partial electrodes are adjacent to second partial electrodes of the partial electrodes, and have irregular shapes on edges adjacent to the second partial electrodes.

  • Patent number: 8493526
    Abstract: A lighting device includes: a light guide plate; a light source disposed on a side face of the light guide plate; and a light modulation element disposed on a surface or in the inside of the light guide plate and adhered to the light guide plate. The light modulation element has a pair of transparent substrates disposed separately and oppositely, a pair of electrodes provided on respective surfaces of the pair of transparent substrates, and a light modulation layer provided in a gap between the pair of transparent substrates. The light modulation layer includes a first region, having optical anisotropy, responsive to an electric field, and a second region, having optical anisotropy, unresponsive to an electric field. The second region has a striped structure with average striped texture size of 0.05 ?m to 10 ?m both inclusive in a short axis direction.

  • Patent number: 8237888
    Abstract: An illuminating device includes a light guide plate, a light source disposed on a side face of the light guide plate, and a light modulation element disposed on a surface or on inside of the light guide plate and joined to the light guide plate. The light modulation element has a pair of transparent substrates disposed apart from each other and opposed to each other, a pair of electrodes provided on surfaces of the pair of transparent substrates, and a light modulation layer provided in a gap between the pair of transparent substrates. The light modulation layer includes a first region and a second region both having optical anisotropy and having response speeds to an electric field different from each other.

  • Patent number: 5390597
    Abstract: A compact, low-height offset press of simple construction is easy to use, needs no after-use maintenance such as cleaning the ink roller and is designed for fully automatic operation. Plate support 1 and blanket support 10 consist of endless belts. Etching unit 60, dampening unit 70 and inking unit 80 are placed along the periphery of the plate support. An unetched plate is supplied from the plate supply unit and etched automatically for printing. When the press is not in use, anti-drying tank 95 moves up, enclosing the roller(s) in liquid, to prevent any ink on the roller surfaces from drying.

  • Patent number: 4267587
    Abstract: An electronic timepiece circuit is provided with an oscillator for producing a reference signal and a frequency dividing circuit which frequency-divides the reference signal from the oscillator to produce a signal with given time intervals. Clock data stored in the memory is read out therefrom by a timing signal corresponding to the output signal from a given stage of the frequency dividing circuit and is loaded into a shift register where it is stored temporarily. The clock data stored in the memory is read out therefrom at given time intervals by a control signal obtained in accordance with the output signal from a given stage of the frequency dividing circuit, and the read out clock data, together with the clock data read out to the shift register, is subjected to a given operation, with the result that the clock data is updated. The updated clock signal is loaded into the memory by a control circuit.

  • Patent number: 4040097
    Abstract: The present invention relates to a magnetic card reader having a motor driven magnetic head sliding on a stationary magnetic card. An error-checking function for the inserted magnetic card is provided. A control means is provided for setting the start of recording and reading out by the magnetic head at a specific distance from the end of said magnetic card. A position control precisely controls movement of the magnetic head along the magnetic stripe of the magnetic card. The magnetic head is supported by two mutually parallel leaf springs, which hold the head always perpendicular to the magnetic card. A motor governor circuit makes the magnetic head move at constant speed.
