Title: Optical catv system
Inventor: SHIBUYA MAKOTO
IPC: H04N7/16
Filed: 1998-06-03
Abstract: PROBLEM TO BE SOLVED: To provide a low-cost optical CATV service for individual subscribers by utilizing a conventional video broadcast service network. SOLUTION: A head end device 10 uses a broad band FM modulator 100 to convert a subcarrier multiplex signal 200, that provides a conventional video broadcast service, into a broad band FM signal 210 and uses this signal to apply intensity modulation to an optical signal 230. On the other hand, FM modulators 310a, 310b convert subcarrier multiplex signals 300a, 300b, that provide a service for individual subscribers, into FM signals 320a, 320b and use the FM signals to apply intensity modulation to optical signals 340a, 340b. The optical signal 230 and the optical signals 340a, 340b are respectively multiplexed and the resulting signals are sent to optical CATV terminals 20a, 20b.  An optical receiver 410a in the optical CATV terminal 20a converts the received optical signal 230, 240a into a high frequency signal 420 and a broad band FM demodulator 430a demodulates the high frequency signal 420a.

Inventor: IOKIDO TADASHI
IPC: G06T7/00
Filed: 1990-06-13
Abstract: PURPOSE:To easily recognize patterns by drawing a feature extraction line in the area where picture data is displayed and extracting parts crossing the pattern and the other parts to obtain membership functions and taking magnifications into consideration to compare membership functions. CONSTITUTION:Binarized picture data is taken in by a picture input part 1, and a feature extraction line is set by a feature extracting part 2 to generate membership functions, and they are stored in a storage part 3. Meanwhile, magnifications to respective fundamental sizes are discriminated by a magnification discriminating pat 4 to perform enlargement or reduction by a means 5. Membership functions of a fundamental character group processed in this manner and membership functions of the recognition object character are used to execute fuzzy inference in a fuzzy inference part 6, and a character which the recognition object character corresponds to is estimated. Thus, features of patterns are automatically obtained by learning and are easily generated as fuzzy membership functions, and an inference rule is easily determined.

Title: Engine equipped with turbocharger
Inventor: OGAWA TAKEO
IPC: F01L1/18
Filed: 1979-11-30
Abstract: PURPOSE: To increase fresh air charging efficiency in a low-speed operational range of an engine, by changing the valve opening timing of the intake and exhaust valves in said operational range to relatively increase exhaust-gas energy imparted to a turbocharger.  
     CONSTITUTION: When engine speed becomes lower than a predetermined speed, pressure P in the intake passage acted to a diaphragm means 22 is lowered. Resultantly, a diaphragm 23 of the diaphragm means 22 is moved to the right by a return spring 26, so that a limit switch 25 is turned OFF by a rod 24. This causes a three- way solenoid valve 18 to open an air cylinder 16 to the atmosphere. Therefore, a piston rod 17 is retracted by a spring 20 and a rocker shaft 12 is turned, by an arm 15, to a position shown by the solid line in the drawing. In this state, an eccentric boss portion 13 of a shaft 12, which is formed integrally with the shaft 12, is displaced from an upper position A to a lower position B to increase the lift and the valve opening time of an exhaust valve 10 as compared with those of valve 10 in a high-speed operational range of the engine.

Abstract: PROBLEM TO BE SOLVED: To provide a production process for an emulsion resin composition which gives a coating layer excellent in abrasion resistance, adhesion, water resistance and the like and is stable even in a high concentration (high resin content) by itself. SOLUTION: In the presence of an aqueous solution containing 1-95wt.%, based on the whole resin components, of the urethane resin prepared by polymerizing a monomer composition containing polyhydroxy-carboxylic acid corresponding to 20-150mgKOH/g calculated as an acid value on the resin solid basis in the water-based urethane resin and in the absence of a surfactant, one or more kinds of radically polymerizable monomers are polymerized in an amount of 99-5wt.% of the whole resin component. The application of the coating emulsion composition produced by this production process can manifest a coating layer of excellent rust-proof properties and adhesion to the substrate. In addition, since no surfactant is used, this composition can develop a coating layer of excellent resistance to water and saline solution.

Title: Superlattice structure semiconductor device
Inventor: MITSUYU TSUNEO
IPC: C30B29/68
Filed: 1989-06-16
Abstract: PURPOSE:To acquire good electrical and optical performance by providing a superlattice layer which is formed by laminating a plurality of thin zinc sulfide layers and thin zinc telluride layers on a buffer layer alternatively. CONSTITUTION:A device is composed of an indium phosphate single crystalline substrate 1, a superlattice layer 2 which is formed by laminating a plurality of zinc sulfide layers 2a and zinc telluride layers 2b, and a buffer layer which is formed by making epitaxial growth of cadmium sulfide. In this case, a lattice constant of cadmium sulfide approximately coincides with that of indium phosphorus or a substrate, which enables good epitaxial growth. The cadmium sulfide buffer layer 3 also shows a tendency of three dimensional island-shape growth immediately after beginning of growth; however, after a growth of several tens of Angstrom  or more, it shifts to a two dimensional growth and a flat surface can be acquired at an atomic level. As a result, the superlattice layer 2 which has a grown on the buffer layer 3 grows two-dimensionally just after beginning of growth and a good and flat superlattice without defects can be acquired. Good electrical and optical characteristics can be realized in this way.

Title: High breakdown voltage semiconductor integrated circuit device
Inventor: YAIDA OSAMU
IPC: H01L29/06
Filed: 1989-06-17
Abstract: PURPOSE:To prevent breakdown voltage from being lowered owing to reach- through right underneath a wiring by forming a conductive layer underneath the electrode wiring insulating it with an insulator film from a substrate and from the electrode wiring and being short-circuited to a guard ring. CONSTITUTION:Upon operation of a high breakdown voltage MOSFET, positive supply voltage +V is applied to a drain region 30 and a source region 28 is grounded. Potential at a guard ring 32 is raised in a positive direction as the voltage is applied to the drain region 30, and the potential at a conductive layer 40 is also positive. In a region through which a wiring is laid the positive potential conductive layer 40 exists on a substrate 26 through a gate oxide film 34, so that a substrate 26 surface just underneath the wiring 36 is prevented from being depleted and hence breakdown voltage of the device is prevented from being lowered. Since the same potential conductive layer 40 as guard ring potential is similarly existent also just underneath a gate electrode wiring, reach-through is prevented from occurring when the gate electrode potential is 0V. Hereby, breakdown voltage of a high breakdown voltage MOSFET can be prevented from being lowered.

Abstract: PROBLEM TO BE SOLVED: To provide the space diversity in-phase synthesizer in which reverse phase locking is prevented. SOLUTION: A phase shift means 10 changes a phase of a sub reception signal to make a phase of a main reception signal in matching with the phase of the sub reception signal.

A phase shift control means 40 controls the phase shift of the phase shift means 10 based on the detected phase difference. A reverse phase state restoration control means 50 conducts restoration control to allow the phase difference to be escaped from the reverse phase when the phase difference is fallen into the reverse phase.
