Abstract: PROBLEM TO BE SOLVED: To suppress energy cost by generating a signal indicative of the presence of a working object in a gas hood and controlling the quantity of the air being purged from the gas hood in response to that signal thereby optimizing the flow rate of the gas hood. SOLUTION: A gas hood 60 is provided, at one inner end thereof, with a plurality of light emitting devices 142 each facing a photodetection device 146 disposed the other end thereof in order to detect presence of an object along the optical path. A gas hood controller controls the air flow in the gas hood as a function of the absence of an object or the position of an object present in the gas hood. The controller sets a minimum allowable gas flow when an object is not present in the gas hood. When all objects are present within about 2 inch from the back face of the gas hood, the current velocity is decreased down to about 50% of the nominal mean surface velocity. When the objects are present within about 6 inch from the front face of the gas hood, the nominal mean surface velocity is sustained. When the objects are present between 6 inch from the front face and 2 inch from the back face of the gas hood, the current velocity is controlled in proportion to the distance.

Title: Nonlinear optical element
Inventor: TAJIMA KAZUTO
IPC: G02F1/35
Filed: 1990-04-20
Abstract: PURPOSE:To prevent an operating speed from being limited by the relaxation time of electrons or holes by impressing a static electric field to a region consisting of the optical nonlinear material of a light guide region. CONSTITUTION:This optical element has the light guide region having the region of a material exhibiting cubic optical nonlinearity (X<(3)>) and has an electric field impressing means which impresses the static electric field to the region of the material exhibiting the optical nonlinearity of this light guide region. Light to be controlled is made incident from a port A and is bisected by a beam splitter 1. The one of the beams arrives via a mirror 3 at a beam splitter 2. The other beam is reflected by a multilayered dielectric film mirror 4 and is then made incident on a nonlinear waveguide 5 which is one of the nonlinear optical elements, where the beam is subjected to a phase change. The beams are thereafter multiplexed by the beam splitter 2. The multiplexed component appears in the port C or port D by the relative phase difference between the two beams at the time of multiplexing. The relative phase difference is generated while the beams propagate in the nonlinear waveguide. The operating speed is prevented from being limited by the relaxation time of the carriers in the nonlinear optical material to be used.
