IPC: G02B27/28
Filed: 1997-01-16
Abstract: PROBLEM TO BE SOLVED: To provide a 1/2 wave length plate which can be used for a light isolator even if thickness accuracy is finished comparatively low by constituting it of a uniaxial crystal on which a refractive index difference between an ordinary ray and an extraordinary ray is a specific value. SOLUTION: In a light isolator, a Faraday rotor 2 and a 1/2 wave length plate 4 are arranged between a first polarizer 1 and a second polarizer 5. The 1/2 wave length plate 4 is constituted of a uniaxial crystal on which a refractive index difference (Δn=|no -ne | between an ordinary ray and an extraordinary ray is not more than 0.01. A transmitted light wave length of the 1/2 wave length plate 4 is desirable to be λ=1200 to 1600nm. It is also desirable that the uniaxial crystal to constitute the 1/2 wave length plate 4 is LiTaO and a transmitted light wave length is λ=1500nm. The 1/2 wave length plate 4 becomes the high extinction ration since the refractive index difference Δn is small. The light isolator using this 1/2 wave length plate 4 can obtain high isolation.

Title: Photodetector
Inventor: ITO MASATAKA
IPC: G02B6/122
Filed: 1987-01-16
Abstract: PURPOSE:To surely receive demultiplexed optical signals without crosstalk by making intervals of one-side ends of light receiving parts different from those of the other-side ends in an integrated photodetector where plural light receiving parts are integrated on the same plane. CONSTITUTION:Integrated light receiving parts are arranged sectorally, and light receiving parts 1, 2 and 3 of the photodetector where three light receiving parts for three-wave multiplex transmission are integrated are arranged fanwise with a point S as the center, and intervals of light receiving parts are D1 in a position A, where optical signals of three waves are made incident, and are D2 in a position and are D3 in a position C. Though convergence intervals of optical signals emitted to the end face of a substrate are D2 on the design, they may be actually deviated from the design value D2 by IDELTAd because of the shape error of lens production, the production error of a diffraction grating, and the wavelength set error of a used light source. Since light receiving parts 1, 2, and 3 are integrated sectorally in accordance with D1=D2-DELTAd and D3=D2-DELTAd, optical signals are surely received even in case of deviation.

Abstract: PURPOSE:To reduce the shock generated at the time of opening a control valve, by a method wherein normally closed control valves are provided in at least some (not one) of intake pipes and the control valve is instantaneously opened to a predetermined valve position exceeding the irregular-combustion range in response to an opening signal of the precedingly opened one of the control valves. CONSTITUTION:When the engine started, a negative pressure is generated in each of the intake pipes 11-13. The negative pressure in the intake pipe 11 is conducted into an actuator 10 through a directional control valve 13 which actuates the control valve 21 through a rod 111 and a lever 31 so that the valve 21 is instantaneously opened to the predetermined valve position exceeding the irregular-combustion range. At this point, however, other actuators 102, 103 are not supplied with the negative pressures because directional control valves 202, 203 are closed. Therefore, a fuel-air mixture is supplied only to a cylinder 191. Then, depressing the accelerator pedal causes a throttle valve 5 to open through a wire 17 and, simultaneously, the control valve 21 is opened through a link rod 6 and the directional control valve 202 is also opened. At this time, therefore, the control valve 22 is instantaneously opened to the predetermined valve position exceeding the irregular-combustion range by the actuator 102.
