Title: Heat treating method for compound semiconductor
Inventor: TAKAHASHI KAZUHISA
IPC: C23C16/455
Filed: 1981-04-16
Abstract: PURPOSE:To perform heat treatment with the decomposition of the compound semiconductor under treatment being suppressed, by increasing the temperature of a second furnace, introducing atmospheric gas, decomposing a same compound semiconductor as the semiconductor under treatment, and supplying the gas, which is filled up with elements, to a first furnace. CONSTITUTION:The temperature of a quartz glass crucible 5 containing InP4 is heated up to 800 deg.C, and the crucible is placed in the second furnace 2 wherein N2 flows. InP4 is decomposed in the furnace 2 under the high temperature, and N2 is filled up with evaporated P. Said atmospheric gas is sent to the first furnace 1. After 10min, an InP substrate 6 on which Si3N4 is to be grown is put in a quartz glass boat 7 and placed in the furnace 1 at the temperature of 650 deg.C. After 10min, NH3 and SiH4 are supplied to the furnace 1. In the furnace 1, new evaporation of P into the atmosphere due to the decomposition of the InP substrate 6 is suppressed. Therefore, when the supply of the source gas is stopped after 20min and the boat 7 is taken out of the furnace 1, the InP substrate 6 is not decomposed, and an Si3N4 film is layered. This method is convenient and effective for the heat treatment of the compound semiconductor which is readily decomposed.

Title: Outline extraction method using multifractal analysis
Inventor: JIYAMARU REZOU
IPC: G06V20/13
Filed: 1996-03-15
Abstract: PROBLEM TO BE SOLVED: To provide a method for eliminating or at least reducing unsatisfactory minimum value in a potential image, specially, one that is caused by texture change at the time of extracting a construct outline. SOLUTION: The method for extracting a contrast zone in a digital base image is based on the minimization of initial, active outline energy which receives force of constraint. The digital base image consists of pixels which have various intensity levels that define a contrast zone to define a boundary. A potential image where each element of the potential image shows a local fractal dimension ((α) in the neighborhood of corresponded pixels in the base image is acquired from multi fractal analyses 10 and 20 of the base image. Thereby, when an active outline is transformed by the action of force of constraint, behavior of the active outline can be improved.

Title: Bus coupler
Inventor: INAO KIYOHARU
IPC: H03H7/38
Filed: 1983-04-05
Abstract: PURPOSE:To increase permissible circuit capacity by setting the characteristic impedance of a bus coupler higher than that of a line and attaining the matching with the characteristic impedance of the line when a transceiver is connected. CONSTITUTION:In a figure, L0 and C0 are the inductance and capacitance of the line and L, C, and (r) are the inductance, capacitance, and resistance of the coupler. The parallel circuit of Ri and Ci is the equivalent circuit of the transceiver. The increase in capacity originating from the connection of the transceiver is compensated by making the inductance L larger correspondingly. The inductance L of the bus coupler is selected properly so that L>L0, and consequently the matching with the characteristic impedance R0 is obtained when the capacitor C of the transceiver is added. Further, the matching with R0 is attained by setting the resistance (r) of the coupler properly even to the resistance Ri of the transceiver.

Abstract: PURPOSE:To obtain a light AND circuit by applying the output voltage of an element formed near the coupling part between an output light waveguide part of a Y branched light waveguide and an input light waveguide part of a Mach- Zehnder type light waveguide to an electrode formed on one branched light waveguide part of the Mach-Zehnder type light waveguide. CONSTITUTION:When an input light signal IinA is ''1'' and an input light signal IinB is ''0'', light made incident on the input light waveguide part 21 is transmitted through the light waveguide parts 23, 31 and equally divided into two branched light waveguide parts 33, 34 by the Mach-Zehnder type light waveguide 3 and transmitted through these parts 33, 34. During the transmission of light through the parts 23, 31, electromotive force is generated from an electromotive force element 4 and applied to the electrode 5. The phase of the light transmitted through the part 33 is previously adjusted by the voltage applied to the electrode 5 so as to be shifted by pi. The light transmitted through both the parts 33, 34 generate the phase difference of pi, and when these light rays are combined at the part 32, the light power becomes ''0'' and a light signal Iout outputted from the part 32 becomes ''0''.
