Title: Optical coupler
Inventor: NISHIWAKI SEIJI
IPC: G02B27/28
Filed: 1990-07-09
Abstract: PURPOSE:To enhance coupling efficiency and to compatibly establish the max. efficiency condition and coupling efficiency stabilizing condition as well as to widen the latitude to errors by equaling the electric field vectors of the incident light on an optical coupling means to each other in the diagonal position centering at the optical axis. CONSTITUTION:The light emitted from a semiconductor laser 1 is focused by a condenser lens 2 to the convergent light focusing at a point F. This light is passed through a polarization converting element 3a and is thereby polarized to the polarized light in which the electric field vector deviates by pi in phase with a straight line existing in the tangent direction of the circle and passing the center of the circle as a boundary. The light is made incident on a circular coupler 5 having the concentrical grating which is formed on a waveguide layer 4 orthogonal with the optical axis. The incident light 6 is inputted and coupled by the coupler 5 and is made into the guided light 7 propagating to the outer peripheral side from the center O of the coupler 5. Namely, the input light 6 has the vectors in which the electric field vectors in the diagonal positions with the center are equal to each other. The coupling efficiency is enhanced in this way and the max. efficiency condition is satisfied by the small coefft. value of a radiation loss. The latitude to errors is widened by the moving adjustment of the coupler.

Title: Method for detecting etching end point of compound semiconductor epitaxial wafer
Inventor: KATO TOSHIHIRO
IPC: H01L21/306
Filed: 1996-07-10
Abstract: PROBLEM TO BE SOLVED: To provide a method for detecting etching end point by which a desired depth of etching can be obtained even in the case of a wafer on which it is difficult to provide an etching controlling layer. SOLUTION: A current blocking layer 24 and a constricted current application layer 20 are formed through a visible light reflecting layer 22 which is approximately 35nm thick and with a refractive index different from those of the two layers. The current blocking layer 24 is subjected to etching. White light is applied from above the surface 32 and the reflected light is detected. The end of the etching is judged when blue light disappear from the reflected light. When white light is applied to a wafer 38, the light is reflected and interfered according to the difference of refractive index at the surface and at the rear of the visible light reflecting layer 22. The thickness of the visible light reflecting layer 22 is set for generating interference color of the blue light.  During erosion of the current blocking layer 24, reflected light in which blue light is made strong is detected. When the depth of etching reaches the predetermined depth and the thickness of the visible light reflecting layer 22 is changed, the blue light disappear substantially.

Filed: 1983-09-28
Abstract: PURPOSE:To easily obtain the well having a impurity concentration inside higher than in the surface by a method wherein a film of the same conductivity type as that of a semiconductor substrate is superposed on a layer of the revese conductivity type in the substrate and then treated by diffusion. CONSTITUTION:A resist mask 21 is applied to the N type semiconductor substrate 1, the surface concentration being set at about 2X10<19>/cm<3> by B ion implantation, and annealing being then carried out at approx. 1,000 deg.C for 30min. Next, an N<-> epitaxial layer 24 is formed. At this time, reduction of the speed of growing the epitaxial layer causes the B of a diffused layer 23 to reach the surface of the layer 24 by outer diffusion, resulting in the formation of the well 25. Then, its impurity profile comes to have the maximum concentration in the neighborhood of the boundary between the layer 24 and the substrate 1, and the concentration becomes lower as it goes closer to the surface. Therefore, this well enables the reduction in the current amplification factor of a parasitic transistor and the prevention of latch-up.

Title: Noise restriction method in system for monitoring damage of buried pipe
Inventor: SUYAMA KENJI
IPC: G01N27/20
Filed: 1995-07-18
Abstract: PROBLEM TO BE SOLVED: To prevent a damage from being detected wrong by A/D converting time series data of a receiving voltage, process the data by a method of moving average and comparing values between a present time point and a preceding time point. SOLUTION: An unprocessed data of a receiving voltage when a damage simulation signal is applied at a time point t2 to a buried pipe where a noise current of a high frequency runs is as shown by (a). The receiving voltage decreases large after the time point t2 , and suddenly drops once at a time point t1 by pulse noises. The unprocessed data of (a) is processed by a method of moving average with a rectangular weighing function, whereby a data of (c) is obtained with noises of the high frequency removed. A decrease width at the time point T1 is reduced. When the receiving voltages of adjacent sampling time points are sequentially processed/compared, a data of (d) is obtained and peaks at the time points t1 , t2 are turned small. Noises of the high frequency are nearly eliminated.  A data of (e) is obtained by processing the unprocessed data by the method of moving average with a triangular weighing function, wherein the dullness of a wavelength at the time points t1 , t2 is improved. A damage can be distinguished and detected in this manner separately from the pulse- like decrease of the voltage.
