Patent JP-S62203124-A (JP)
Title: Liquid crystal display device
Inventor: HOSHIKAWA JUN
IPC: G02F1/133
Filed: 1986-03-03
Abstract: PURPOSE:To easily invert a negative and a positive display mode partially and to obtain the degree of freedom of displaying by sandwiching a birefringent plate partially between a glass substrate and a polarizing plate between which a twist-oriented liquid crystal layer is sandwiched so that light shifts in phase by a half. CONSTITUTION:When a 1/2lambda plate 20 is inserted, light has its plane of polarization rotated by 90 deg. through the 1/2lambda plate to make a bright display in the absence of no applied voltage and a dark display in the presence of an applied voltage, thereby inverting the negative display mode to the positive display mode by the insertion of the 1/2lambda plate. A drawn film such as a drawn polyester film, a drawn polypropylene film, a drawn cellophane film, and a drawn poly(vinyl acetate) are inexpensive and usable as the raw material of the 1/2lambda plate in addition to a mica plate. The 1/2#. plate is used normally shifting in optical axis from an axis of incident polarized light by 45 deg.. The 1/2lambda plate whose one surface is made adhesive is used and stuck for fixation with good position accuracy.

Title: Optical branching coupler
Inventor: TANAKA TSUTOMU
IPC: G02B6/34
Filed: 1978-04-19
Abstract: PURPOSE:To eliminate insertion loss of light in a simple constituion, by disposing optical fibers to propagate lights of differnt wavelengths of each end face of self- converging lens to converge lights of different wavelengths. CONSTITUTION:Wavelengths lambda1, lambda2 are set at 0.83 mum, 1.3mum, respectively. When a rod lens 5 of multicomponent glass material measuring 1 mm in diameter is used, period lengths L1, L2 of wavelengths lambda1, lambda2 become 11.14 mm, 12.58 mm, respectively. Therefore, when the length of the lens 5 is set to 50.1 mm, the light of wavelength lambda1 is converged at an end face B beneath the axis of the lens 5, while the light of wavelength lambda2 is converged at a point 0.2 mm behind the end face B above the axis of the lens 5. When optical fibers 8, 7 are secured to these positions respectively, the lights of wavelengths lambda1, lambda2 propagate through the optical fibers 8, 7. Epoxy resin or the like may be buried in the space between the end face B of the lens 5 and the optical fiber 7. Thus, in a simple constitution, the insertion loss of light may be almost completely eliminated.

Output from an acceleration regulator 4 is inputted to the function generators 5, 6. Outputs from the function generators 2, 5 are inputted to a current limitation modulator 7 to produce a current limitation signal S7. A conduction rate modulator 8 commands a conduction rate S8 based on the outputs from the function generators 3, 6. A current limitation operating unit 9 determines the difference from an actual current detected through a current detector 10 and outputs a conduction rate lowering signal S9. A conduction rate is created 12 based on an average applying voltage determined by subtracting the signal S9 from the signal S8 and thus created conduction rate is employed for switching a switch 13 of a motor 14. According to the constitution, operation of an electric drive vehicle can be fitted to each driver.
