Abstract: PURPOSE: To provide a nonlinear fully optical space optical switch which can be operated at a speed higher than 100GHz by providing an optical waveguide where interacting light beams are confined. CONSTITUTION: This fully optical switch includes a waveguide which is formed as a nonlinear optical medium by a conjugate organic material, and the conjugate organic material can be processed and has a large third-order optical nonlinearity X<(3)> larger than 10<-10> esu. In this case, the four-wave mixture method is used for space switch light in frequency and time domains dependent upon the third-order optical nonlinearity of the conjugate organic material in the waveguide. The waveguide is used to not only keep the intensity of light high for a long distance but also confine the light to enhance the effect of X<(3)> . That is, light beams 13 are coupled on the inside and the outside of the thin film waveguide, and for example, this coupling is evanescent wave prism coupling passing a prism 14. Thus, the optical switch can be operated in a band width exceeding 100GHz.

IPC: F01L1/18
Filed: 1984-10-29
Abstract: PURPOSE:To ensure a sufficient amount of intake-air and to prevent the rotational speed of an engine from lowering when operating mode is turned into the load operation from the idling operation, by setting the area of lift-time in a predetermined range upon idling operation. CONSTITUTION:The rotational speed NE of an engine is compared with a predeter mined rotational speed NC. If the speed NE is below the predetermined rotational speed NC, whether a clutch is turned on or off is discriminated. If the clutch is turned off, the condition of the idle operation is discriminated, and therefore, the area value P of lift-time of an intake valve to set to be small. When the clutch is turned on, whether a gas is neutral position or not is discriminated. If the bear is in the neutral position, it is judged that the engine is in the idle condition, and therefore, the area value P is set to be small. If the gear is in a position other than the neutral position, or if the rotational speed NE of the engine exceeds the predetermined rotational speed NC, it is discriminated that the engine is in the load condition, and therefore, the area value P of lift-time is set to be large. With this arrangement it is possible to ensure a sufficient amount of intake-air upon transient of load operation.

Title: Fixing device
Inventor: TOMOYUKI YOJI
IPC: G03G15/20
Filed: 1990-08-31
Abstract: PURPOSE:To provide the fixing device which is decreased in triboelectrostatic charge at the time of paper passing and has an excellent release property over a long period of time by providing a layer consisting of a mixture composed of fluororubber and fluororesin and having <=1mm thickness on the front layer of a conductive rubber layer. CONSTITUTION:The front layer 22A consisting of the mixture composed of the fluororubber and the fluororesin is formed on the conductive rubber layer 22. The thickness of the front layer 22A consisting of the mixture composed of the fluororubber and the fluororesin is <=1mm, more preferably <=0.1mm. The triboelectrostatic charge voltage increases and a sufficient offset preventive effect is not obtainable if the thickness of this front layer 22A exceeds 1mm. The fluororesin is a tetrafluoroethylene resin or tetrafluoroethylene/ perfluoroalkoxy ethylene copolymer or tetrafluoroethylene/hexafluoropropylene copolymer. The triboelectrostatic charge is decreased by the conductive rubber layer at the time of the paper passage in this way and a release property is maintained by this front layer. The offset quantity is thus decreased and the release property excellent over a long period of time is obtd.

Title: Contaminant film measuring method and its device
Inventor: WATANABE MASAHIRO
IPC: H01L21/66
Filed: 1986-09-29
Abstract: PURPOSE:To rapidly measure contaminant films scattering on a semiconductor wafer, by detecting an angle of reflection on the semiconductor wafer at the time of generat ing no thermal expansion of the light of a probe, and that at the time of generating the cyclical displacement of the light by the thermal expansion. CONSTITUTION:When excitation light A is projected from a condenser lens system 6, a slope 14 is generated periodically on the surface of the semiconductor wafer 15 by the thermal expansion, setting the center of an irradiation area as an apex. Meanwhile, when probe light B from a probe laser 7 is projected toward a position where the slope 14 is generated, the light B is reflected along a chain line C with an angle theta from the projecting position of the excitation light A at the time of generat ing no slope 14, and is reflected along continuous line C' with an angle theta' on the slope 14 at the time of generating the slope 14. Therefore, the positions of the reflected light C and C' are detected 8, and detected signals P are amplified 9, then, are mea sured by a phase detector 10. Since detected periodic fluctuation on the surface of the wafer 15 varies depending on the presence or absence of the contaminant film, a surface displacement signal varies by the existence of the contaminant film when the scanning stage 16 is scanned in the X or the Y direction or the like, and it is possible to measure the existence of the contaminant film rapidly.

Title: Prevention method of erroneous mode detection by gain switching
Inventor: MURATA HIROYASU
IPC: H04N1/32
Filed: 1983-12-03
Abstract: PURPOSE:To detect an envelope having correct mode signals by setting an input of a preparation circuit of a threshold to OFF at the time of detecting a mode so that a transient generated at the time of gain switching in roder to secure an input signal level can be covered. CONSTITUTION:An input signal immediately after a multiplied point 13 is divided and inputted to an input mean value calculation circuit 11, and an average level in the prescribed range is calculated. If the level is below a certain zone, an H signal is given to an gain switch changeover circuit 12 and returned. If the level exceeds the certain zone, an L signal is given to said circuit 12 and returned. A multipled point 14 is provided just before a peak-type integrator 1, and an output at the multiplied point 14 is turned OFF for a definite period from a switching point of the changeover circuit 12, that is for the period to cover the generation time of a transient. Thus the peak-type integrator 1 can be held in almost the same level as that just before the OFF state, the value comes to be supplied to the posterior stage, and therefore fluctuation of a threshold due to gain switching can be prevented.
