Title: Led for light source
Inventor: OOTA TAKEYORI
IPC: F21S2/00
Filed: 1985-03-19
Abstract: PURPOSE:To increase illuminance largely, and to improve general-purpose properties by integrally combining a LED and a total reflection lens, forming an approximately parabolic curved surface, on which luminous flux radiated in the direction of the side surface of the LED is total-reflected to the front surface side, to the total reflection lens and prism-cutting the front surface of the total reflection lens. CONSTITUTION:Luminous flux (a) from the top section 13 of a LED in luminous flux radiated from a light-emitting element 12 for the LED 11 passes through a total reflection lens 15 as approximately parallel lines as it is and is extracted to the outside, and luminous flux (b) radiated from the side surface 14 of the LED is total-reflected to the front surface side by an approximately parabolic curved surface 17 in the total reflection lens 15, passes through the total reflection lens 15 and is extracted to the outside. Since the front surface of the total reflection lens 15 is formed to a prism cut 18 at that time, luminous fluxes (a), (b) extracted to the outside on the basis of the inclination of the prism cut is polarized at fixed angles. The degree of polarization is determined by the angle of the prism cut 18. Luminous flux radiated to the outside by the prism cut 18 can be polarized in the arbitrary direction in either case.

Title: Bidirectional optical transmitter
IPC: H04B10/00
Filed: 1992-03-16
Abstract: PURPOSE:To provide a bidirectional optical transmitter which is free from the noises by providing the signals having the same phases and levels and the adverse polarities and then canceling these signals by means of the signal which transmits the reflected wave generated by an optical connector from its own station. CONSTITUTION:The transmitted data are inputted to a laser diode 12 via a driver 11 and converted into the optical signals. These optical signals are sent to an optical transmission line via an optical directional coupler 30 and the optical connectors C1 and C2. The reflected wave of the connector C1 is inputted to a photodetecting element 22 through the coupler 30 and then inputted to a mixer 71 via an amplifier 21. Meanwhile the optical signal of its own station that is outputted from a 2nd output terminal of the coupler 30 is inputted to a variable delay circuit 51 via a photodetecting element 42 and an amplifier 41 to undergo the matching of the phase with the reflected wave and also to undergo the matching of the level with the reflected wave through a variable attenuator 61. Such optical signal is inputted to a mixer 71 and the reflected wave is canceled by the mixer 71. In such a way, the reflected wave of the optical connector is canceled by the signal transmitted from its own station. Thus it is possible to obtain an inexpensive bidirectional optical transmitter which is free from the noises.

Title: Method for screening coated optical fiber
Inventor: KOBAYASHI HIROYUKI
IPC: G01M11/00
Filed: 1992-02-05
Abstract: PURPOSE:To prevent the coating film of an optical fiber to be subjected to screening tests from being stripped off or damaged by constituting the surface of a reel with which the coated optical fiber is brought into contact while tension is applied to the optical fiber of a material having a Young's modulus which is lower than a specific value. CONSTITUTION:In the title screening method in which prescribed tension is added to a coated optical fiber which is run between a pair of reels, the hardness (Young's modulus) of reels 5A and 5B for screening and a guide reel 4 largely affect the stripping off or crashing of the coating film of the fiber 1. Therefore, the surfaces of the reels 4, 5A, and 5B with which the fiber 1 are brought into contact while tension is applied to the fiber 1 are constituted of a material having a Young's modulus which is equal to or lower than 1,000kg/mm<2>. As a result, even when the coated optical fiber 1 is brought into contact with one of the reels while a tension load is applied to the fiber l, the coating film of the fiber 1 is hardly stripped off or crashed, because the Young's modulus of the surface of the reel is relatively small, being equal to or lower than 1,000kg/cm<2>.
