  • Patent number: 6987571
    Abstract: A sensor head has a multiplicity of linear image sensors in correspondence with different radial directions of light emitted from a pixel in a pixel line of an LCD panel. The linear image sensors extends in the direction of the axis of an imaginary semi-cylinder. The linear image sensors have light receiving faces that are angularly spaced apart on an imaginary semi-cylinder, with their light receiving faces having normals passing through the axis of the imaginary semi-cylinder. Interposed in the space between the LCD pixel and the linear image sensors is an optical system having a multiplicity of light paths associated with respective angular components of the radiation emitted from the pixel line. Each of the light paths receives a predetermined angular component of light and transmits the light thus reveived to a corresponding one of the linear image sensors.

  • Patent number: 6894711
    Abstract: A coreless thermal transfer recording web roll 10 is formed by rolling a thermal transfer recording web 10a in a roll. An inner end part 11 of the thermal transfer recording web 10a of the thermal transfer recording web roll 10 has a tab 11a formed at a substantially middle of the inner end part 11, and sticking parts 11b formed on the opposite sides of the tab 11a, respectively. Pseudoadhesive double-coated tapes 14 are attached to the sticking parts 11b, respectively. The pseudoadhesive double-coated tapes become tack-free after the sticking parts 11b have been separated from the innermost layer of the thermal transfer recording web 10a of the thermal transfer recording web roll 10.

  • Patent number: 6690405
    Abstract: A thermal transfer printer includes a thermal transfer recording web roll having a bore and obtained by rolling a thermal transfer web. The segment of the thermal transfer recording web forming the innermost layer of the thermal transfer recording web roll is fixed to a part of a segment of the same forming the second innermost layer of the thermal transfer recording web roll. A holding device is inserted in the bore of the thermal transfer recording web roll to hold the thermal transfer recording web roll. The thermal transfer recording web roll and the holding device rotate in a unit to feed the thermal transfer recording web to a thermal transfer recording unit that forms images on the thermal transfer recording web. The thermal transfer recording web roll can be prepared at a low cost without requiring much time and effort.

  • Patent number: 5444275
    Abstract: Gate width directions of transistors are taken in circumferential directions surrounding a certain point as a center. Or transistors are constructed by a plurality of straight lines extending in radial directions of the certain point and intersecting each other at the same angle. Hereby, basic cells can be assembled on a master slice symmetrically in plural directions. There are arranged in a mutual adjacent relation in which channel layers located under one opposing gate electrodes are formed into P channels and channel layers located under the other opposing gate electrodes are formed into N channels. Otherwise, there are arranged alternately with respect to P channels and N channels in an adjacent relation basic cells in which all channel layers located under all gate electrodes in the same basic cell are formed by any type of the P channel and the N channel.

  • Patent number: 5187556
    Abstract: A CMOS master slice having a plurality of regularly arranged basic cells improves an integration efficiency by optimizing size and arrangement of MOS transistors in the basic cells. Each of the basic cells comprises a first pair of transistors having gates thereof arranged to parallelly face each other, and a second pair of transistors having gate electrodes shorter in gate width than that of the first pair of transistors and parallel to the gate electrodes of the first pair of transistors. In adjacent basic cells, the gate electrodes of adjacent second transistors are substantially on a line so that a wasteful space is eliminated.

  • Patent number: 4883234
    Abstract: Reels for carrying a sheet-like medium wound thereon are provided in parallel relation in a cassette case in a manner rotatable and shiftable longitudinally of the reels. A reel-biasing leaf-spring assembly is provided adjacent to one longitudinal end of each reel to bias the reel in a longitudinal direction. The leaf-spring assembly has a leaf-spring portion exerting the biasing force to the reel via an end projection on the reel, and rotation preventing arm angularly extending from the leaf-spring portion to normally engage a rotation preventing stub shaft carrying said projection thereon, the stub shaft having thereabout a plurality of flat outer surfaces one of which is engaged by said rotation preventing arm, whereby the reel is prevented from rotation. When the cassette is fitted in a printer, for example, the reel is shifted longitudinally against the force of the leaf-spring assembly, and the rotation preventing arm is moved away from the stub shaft so that the reel is allowed to rotate.
