Title: Flush type waveguide type optical switch
Inventor: YOSHIMOTO NAOTO
IPC: G02F1/313
Filed: 1992-04-27
Abstract: PURPOSE:To obtain the good electrical insulating characteristic between two pieces of adjacent optical waveguides by embedding the circumference of a core layer with a semi-insulating medium. CONSTITUTION:This flush type waveguide type optical switch is constituted of a (p) side electrode 101, a p-InP substrate 102, an i-MQW core layer 103, an i-InGaAsP etch stop layer 104, an i-InP etch stop layer 105, a core layer 106 added with i-InGaAsP, an n-InP layer 107 doped with Si, an (n) side electrode 1-8 and a semi-insulating PnP embedding layer 109 doped with Fe. The Si which is the dopant is prevented from diffusing into the insulating InP embedding layer 107 by forming the n-InP layer 107 constituted by doping the Si in the conductive clad layer existing in the upper part of the i-MQW core layer 103 in such a manner. Then, the good electrical insulating characteristic between two pieces of the adjacent optical waveguides is attained.

Title: Impurity doping method
Inventor: SAMEJIMA TOSHIYUKI
IPC: C23C16/30
Filed: 1986-05-12
Abstract: PURPOSE:To improve the controllability of doping by a method wherein the decomposition of doping gas for vapor phase growth of an impurity-contaning layer is performed by a beam parallel to the surface of a substrate and the heating for diffusing the impurity in the impurity-con-taining layer is performed by a beam inadiating the surface of the substrate. CONSTITUTION:A reaction chamber 3 is always filled with fresh doping gas by supplying the doping gas such as PH3 or B2H6 from a gas supply inlet 6 and by exhausting the gas from an exhaust outlet 7. At the same time, a pulse laser beam (a) is applied to the inside of the chamber 3 through a quartz window 5 by a light source 9 for gas decomposition. The laser beam (a) is absorbed by the doping gas existing on the surface of a semiconductor substrate 2 and the doping gas is decomposed by the beam (a) and impurity produced by the decomposition is deposited on the substrate 2. After a required impurity containing layer 2a is formed like this, a laser beam (b) is applied to the substrate 2 surface by a heat source 8 for doping to heat the surface. With this process, the surface of the substrate 2 is doped with the impurity in the impurity-containing layer 2a formed on the surface of the substrate 2 by hot diffusion.

Title: Regulating system for message transmission
Inventor: MAEDA YUUZOU
IPC: H04L47/265
Filed: 1980-08-11
Abstract: PURPOSE:To regulate message transmission, by counting the residual message with each stored exchanger in a network and rejecting the message input when the count value is more than a prescribed value. CONSTITUTION:When a transmission request from a terminal 3a to a terminal 3b exists, a packet exchanger 1a checks if the number of stored messages exceeds a prescribed value through a counter 4a. If exceeds, the transmission is rejected and if not, a message MES is stored in a reception storage device 2a to set the value of the counter 4a to +1. Next, the packet exchanger 1a picks up the message MES and transmits it to a packet exchanger 1b, which stores it in a storage device 2b and transmits it to the terminal 3b. When the transmission is finished, a transmission completion information ES is transmitted from the device 1b to the 1a, which subtracts the value of the counter 4a by one. Thus, the stored message number can be checked and the transmission can be regulated.

Title: Automatic focus detector for microscope
Inventor: NAGASAWA NOBUYUKI
IPC: G02B7/28
Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To detect a in-focal-point even though contrast values of a front focusing image and a rear focusing image are uneven by providing a means judging an in-focus by the inquiry whether the distance between the relative position between a moved stage and an objective lens and a stored relative position coincides with the distance calculated by a distance calculating means or not, etc. SOLUTION: When the contrast evaluation value of a front focusing image is larger (smaller) than that of a rear focusing image, a stage 1 is moved along an observation axis by a prescribed amount by a driving circuit 16. A position of the stage 1 where the contrast evaluation value becomes maximum is searched by repeating the moving of the stage until the contrast evaluation value of the front focusing image is lowered as compared with that before the moving of the stage 1. This position of the stage 1 is stored in a memory 17 together with the maximum value of the contrast evaluation value of the corresponding front focusing image and the distance between positions of the stage at the point of time when contrast evaluation values of the front and rear focusing images coincide is calculated by a subtraction.  The coincidence between this distance and a theoretical value is judged and the position of the stage 1 at the point of time when they coincide is judged to be an in-focal-point.
