Title: Two-dimensional optical waveguide type te, tm mode splitter
Inventor: MISAWA SHIGEYOSHI
IPC: G02B6/126
Filed: 1989-04-28
Abstract: PURPOSE:To obtain the mode splitter which is low in cost and is strong to a fluctuation in incident angle by providing a 2nd optical waveguide which has a boundary to allow the diagonal incidence of the TE and TM modes from a 1st optical waveguide to guide the TE and TM modes in the same direction and is formed to the film thickness to indicate a non-degeneracy state to these modes. CONSTITUTION:This mode splitter is constituted of the 1st optical waveguide 6 which guide the TE mode and TM mode in the same direction and the 2nd optical waveguide 7 which has the boundary 8 to allow the diagonal incidence of the TE mode and TM mode from the 1st optical waveguide 6 to guide the TE mode and TM mode in the same direction and is formed to the film thickness to indicate the non-degeneracy state to these modes. The fluctuation in the power of refracted light is, therefore, smaller than in the case of a grating system and the above-mentioned power is strong to the fluctuation in the incident angle even if the incident angle on the boundary 8 fluctuates. The influence by the fluctuation in the wavelength is lessened and the permissible range of the wavelength stability of a light source is widened. The degree of freedom in the selection of the light source is increased and the production is easy and low in cost.

IPC: F02M21/02
Filed: 1999-04-20
Abstract: PROBLEM TO BE SOLVED: To provide a fuel injection valve to control a fuel injection amount with high precision even when a fuel injection amount is a small quantity. SOLUTION: In a state that a needle valve 20 seats a vale seat, an initial gap di between a fixed core 12 and a moving core 30, a distance between a spacer 14 and a stopper 23, namely a lift amount dl of a needle valve 20 are in a relation di>dl. Further, a formula of 165 μm<=dl<=220 μm is established.

Abstract: PURPOSE:To prevent the occurrence of a measurement error even when the ambient temperature varies by providing a fixed target prism in the vicinity of a length measuring datum point. CONSTITUTION:A laser beam emitted from a laser oscillator 12 is split into a measurement beam L1 and reference beam L2 by means of an interference beam splitter 16 and the beam L2 is reflected by fixed target prism 20 fixed to a frame 11 near a datum point P0 through a mirror and led to a photoreceptor sensor 4 through a polarization beam splitter for discriminating the forward or backward movement of a mobile target prism 14 incorporated in the oscillator 12 through the splitter 16. On the other hand, the measurement beam L1 advancing straight through the splitter 16 is also led to the photoreceptor sensor through the splitter 16 after being reflected by the prism 14. The photoreceptor sensor outputs bright and dark information obtained from the interference of light caused by the movement of the prism 14 together with the phase information of the beams L1 and L2 and a data processing circuit in a display 30 counts the number of bright and dark fringes and displays the counted number after converting the number into numerical data.
