Title: Liquid crystal display device
Inventor: YAMAZOE HIROSHI
IPC: G02F1/1347
Filed: 1987-10-29
Abstract: PURPOSE:To obtain a liquid crystal display device which can execute satisfactory black-and- white display by laminating and providing a second liquid crystal layer whose refractive index anisotropy is small, in addition to a first liquid crystal layer to which a display signal voltage is applied. CONSTITUTION:A linearly polarized light plate 9, laminated structures 7, 8 containing two liquid crystal layers and a linearly polarized light plate 10 are laminated in said order, and the refractive index anisotropy of a liquid crystal of the second liquid crystal layer 8 is made smaller than the refractive index anisotropy of a liquid crystal of the first liquid crystal layer 7. When a voltage is applied to electrode layers 5, 6, a liquid crystal molecule tries to take an arrangement being parallel to the electric field direction instead of an arrangement of a torsion structure before that time, due to its guidance anisotropy. In such a case, between a tile angle of the liquid crystal molecule and an applied angle, a threshold level characteristic exists, and a driving condition is set so that in a nonselective picture element, a deformation from the torsion structure of the liquid crystal molecule arrangement becomes smaller, and in a selective picture element, said deformation becomes larger. As a result, a double refraction which a light beam for propagating vertically to the liquid crystal layer is subjected to is offset by a compensating effect of two layers, and an emitted light from the second liquid crystal layer 8 goes to a linearly polarized light which scarcely has the wavelength dependency in an azimuth angle.

Title: Metho and device for giving large delay between orthogonal polarized lights of light
Inventor: MACHITORI SEIHAN
IPC: G02B27/28
Filed: 1992-09-17
Abstract: PURPOSE:To provide the delay that only uses a polarization maintaining fiber which is much shorter than usual and gives delay between orthogonal polarized lights of a light. CONSTITUTION:The light which is made incident from a single-mode fiber 4 for incidence is split by a polarization beam splitter 6 into the mutually orthogonal polarized lights. One polarized light is propagated in the polarization maintaining fiber 2 and delayed behind the other polarized light by as much as it is propagated, and both the polarized lights are multiplexed by a polarization beam splitter 6 and projected from a single-mode fiber 9 for projection. A collimator lens 5 is used to couple the fibers 4 and 9 with the polarization beam splitters 6.

Title: Liquid crystal display device and its driving method
Inventor: TOGASHI SEIGO
IPC: G02F1/133
Filed: 1994-11-08
Abstract: PURPOSE: To reduce burning with a simple method by making a voltage polarity of a data signal in a current impressed period of a scanning signal the voltage polarity opposite to the voltage polarity of the scanning signal in the current impressed period. CONSTITUTION: The current impressed period I(n) previous to a selective period S(n) of negative polarity is divided to four discontinuous sub-sections in e.g. the scanning signal ϕ(n). Further, the scanning signal takes selective potential Va1, Va2 of different polarities at the same potential alternately in respective sub-sections. Then, the voltage polarity of the data signal D(m) in the sub-section constituting the current impressed period I(n) of the scanning signal takes the voltage polarity opposite to the voltage polarity of the scanning signal in the current impressed period.  For instance, the data signal takes data potential Vd2 of negative polarity in the sub-section where the scanning signal takes the selective potential Va1 of positive polarity, and the data signal takes the data potential Vd1 of negative polarity in the sub-section where the scanning signal takes the selective potential Va2 of negative polarity.

Title: Device for laying and collecting optical fiber unit
Inventor: OSAWA MAKOTO
IPC: G02B6/46
Filed: 1995-10-23
Abstract: PROBLEM TO BE SOLVED: To smoothly wind a bobbin with an optical fiber unit not forcibly when the optical fiber unit which is laid once needs to be drawn out by monitoring the output of a slack detector and controlling the pressure of an air flow. SOLUTION: The optical fiber unit sent out of a conduit 4 is set on the slack detector 11 and a pinch roller 6 first. Then a control part 17 sends a speed command to a motor 7 and a motor 9 so as to set the frequency of rotation of the pinch roller 6 to a speed at which the fiber unit can be wound around the bobbin. If the slack detector 11 detects a slack while the optical fiber unit 10 is wound around the bobbin, a solenoid valve 15 is closed by one unit so that the slack will substantially be zero. It is judged whether or not the slack is eliminated and when not, the solenoid valve 15 is further closed by one unit. Thus, the solenoid valve 15 is throttled to lower the pressure of the air flow, and the sending-out quantity of the optical fiber unit 10 is reduced to eliminate the slack.

Inventor: SAKAI HIDEKAZU
IPC: H01F21/06
Filed: 1987-10-28
Abstract: PURPOSE:To set the variable range of the inductance of a coil freely, and to give an application circuit for the coil redundancy by utilizing a superconductive substance for a core.
