Title: Process for molecular-beam epitaxial crystal growth
Inventor: KURODA TAKAROU
IPC: C30B23/08
Filed: 1983-07-15
Abstract: PURPOSE:To perform crystal growth in good condition and with high reproducibility in the crystal growth by the molecular-beam epitaxy of a III-V group compound semiconductor contg. plural kinds of V group elements by supplying plural kinds of V group elements by each regulated method. CONSTITUTION:A III-V group compound semiconductor contg. plural kinds of Vgroup elements (e.g. InGaAsP) is subjected to crystal growth using a device for molecular-beam epitaxy. In this case, one kind (e.g. As) of the V group element which is more easily taken in the substrate crystal (e.g. InP) than other elements is supplied by evaporating the simple substance of the element. Other element (e.g. P) which is more difficultly taken in the substrate crystal is supplied by the evaporation of a compd. (e.g. ZnP2, Cd3P2) of the element with an element causing almost no incorporation into the substrate crystal (e.g. Zn, Cd, etc.). The partial pressure of As is monitored by a vacuum gauge and the amt. of injected As is controlled severely taking care to inject P to the site where As is not deposited. By this method, the ratio of As to P is held at a constant ratio.

Title: Heat-resistant resin composition
Inventor: KURITA TOMOHARU
IPC: C08K3/22
Filed: 1994-06-09
Abstract: PURPOSE:To obtain a resin composition improved in heat resistance such as heat softening properties, thermal dimensional stability and thermal decomposition properties without reducing workability of a polyimide resin and useful as a raw material related to printed-wiring board. CONSTITUTION:This resin composition is composed of a polyimide resin and 10 to 40wt.% metal oxide sol (e.g. silica or alumina) having 10 to 100nm average particle diameter and dispersed therein. In addition, dispersion of the metal oxide sol into the polyimide resin is carried out by blending a metal oxide sol with an organic solvent solution of the polymer (a polyamic acid resin which is a precursor may be used). If the dispersion process is carried out especially in the presence of a silane compound (e.g. gamma-glycidoxy- propylmethyldiethoxysilane) or after reaction of the silane compound with the polyimide resin and/or the polyamic acid resin, a more uniform dispersion is preferably obtained.

Title: Word segmenting system
Inventor: TANAKA HIDEAKI
IPC: G06K9/34
Filed: 1991-05-30
Abstract: PURPOSE:To permit an optical character reader which can certainly recognize an alphabet in a fixed pitch document and a proportional document to segment a word. CONSTITUTION:After extracting a line of picture data and segmenting a character, the words are roughly segmented with a threshold between the words obtained with a histogram showing the appearrance frequency of space. The histogram of a pitch showing the distance between the centers of the characters from the whole character gap decided from the result of the rough word segmenting. An inputted document is judged whether a fixed pitch or a proportional pitch based on the variance and the mean of the histogram. When the judgement result is the fixed pitch document, the word segmenting threshold for the fixed pitch is decided based on the mean of a pitch histogram. Then, the word segmenting is processed based on the threshold. When the judging result is a proportional pitch document, the word segmenting is processed based on the threshold between the words.

Abstract: PURPOSE:To obtain a pressure control valve which is simple and compact in its structure and capable of controlling the pressure in proportion to current, by constructing the section subjected to hydraulic pressure in a differential-pressure responsive type, and using a solenoid and a spring in combination.

Therefore, by controlling the current passed through a coil 2 after the maximum pressure is set by adjusting the pre-load of a spring 10 by a screw 11, pressure of the pressure oil 5 is controlled to a required value. Here, if a pressure higher than the preset maximum pressure is impressed from the voltage side, the differential valve 9 is moved to the direction of the arrow 4 and part of pressure oil 5 is passed in the direction shown by an arrow 8 in the drawing, so that an excessive pressure rise is prevented.

Title: Line pressure controller for belt drive type stepless speed change gear
Inventor: TOKORO SETSUO
IPC: F16H61/662
Filed: 1982-07-26
Abstract: PURPOSE:To improve the accuracy in controlling the line pressure of a CVT, by feed-back controlling the line pressure so as to reduce it when an actual value thereof is higher than a target value and raise it when the actual value is lower than the target value. CONSTITUTION:An amplifier 50 for a pressure-regulating valve 15 generates an output electric current which is a linear function of an input voltage Vout, and feeds the current to the valve 15. An output-side servo oil pressure Pout is detected by an oil pressure sensor 34, an output from which is amplified by an amplifier 51, and is fed to an adding point 53a through a processing circuit 52. The result of calculation at the adding point 53a is fed to an adding point 55a through a feed-back element 54a. The result of calculation at the adding point 55a is fed to the amplifier 50, and an input voltage to the amplifier 50 is varied in accordance with Vout*-Vout, based on Vout. Accordingly, when a target line pressure Pl* is higher than the actual line pressure Pl, the return flow rate through the valve 15 is reduced, thereby raising the line pressure Pl, and when the target line pressure Pl* is lower than the actual line pressure Pl, the flow rate is increased, thereby lowering the line pressure Pl.

Title: Pb tone transmission system
Inventor: NAKAMURA KOSUKE
IPC: H04Q1/30
Filed: 1991-05-31
Abstract: PURPOSE:To send a PB tone accurately by delaying a voice A/D conversion processing signal by a PB signal discrimination time so as to present the PB signal from being subject to voice A/D conversion processing. CONSTITUTION:A voice A/D conversion means 301 at a sender A/D-converts a voice signal resulting in being compressed and a pushbutton signal is converted into a digital code by a PB signal A/D conversion means 302. A PB signal discrimination means 303 discriminates whether or not the input signal is a pushbutton signal this time. Then a delay means 305 delays the voice signal for the required discrimination time. As a result, when the section is discriminated to be the PB signal, the digital code from the PB signal A/D conversion means is sent through a selection means 304. A PB signal discrimination means 603 of a receiver side discriminates the PB signal and a PB signal D/A conversion means 602 outputs an analog PB signal. Thus, the voice signal and the PN signal are sent while being discriminated clearly and the PB tone is sent accurately without quality deterioration.
