Title: Image compression encoder
Inventor: AMEMORI TAKEHIKO
IPC: H04N19/00
Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To provide an image compression encoder, which is compatible without extremely expanding circuit scale even when the number of gradations is increased, by transforming the image data of (n) bits to the image data of 8 bits and performing image compression encoding while using an MPEG-2 system for a compressing system. SOLUTION: At a dynamic range converting circuit 15, a maximum value 2<n> -1 of the dynamic range of an input image is inputted to a maximum value 16 of the input image. Besides, a minimum value 0 of the dynamic range of the input image is inputted to a minimum value 17 of the input image. Then, the luminance value of image data 2 is converted into the luminance value of the gradation of 8 bits according to a required expression and outputted as 8-bit gradation image data 18. Next, at an image compression encoding circuit 19, the 8-bit gradation image data are compression-encoded by the MPEG-2 system and encoded image data 4 are outputted. Thus, the encoded image data can be provided by performing compression encoding to the image data having the gradation of (n) bits while using the MPEG-2 system.

Abstract: PROBLEM TO BE SOLVED: To obtain a relatively low-cost, reliable, and low-loss waveguide device which has a passive addition/removal multiplexing function, etc., by providing a specific mode discriminating coupler(MDC) and a reflection mode coupling means. SOLUTION: This system has a device group consisting of an MDC 10 and the reflection mode coupling means arranged between a radiation source and a use means. The MDC 10 is a 4-port (14 to 17) coupler having a 1st multi-mode optical waveguide optical waveguide 12 which is coupled with a 2nd multi-mode optical waveguide 12 by evanescent coupling and is different from it. The evanescent field coupling propagates electromagnetic radiation in basic space mode of wavelength λi on the optical waveguides 1 and 12 through the MDC 10 and couples electromagnetic radiation in high-order space mode from one of the optical waveguides 11 and 12 to the other.  The reflection mode coupling means consists of a reflection mode coupling grating which has such a blaze refractive index grating that the pitch Λ is less than 1μm and the blaze angle θ larger 3 deg. to the length of the multi-mode optical waveguide.

Title: Part mounter
Inventor: HAMAZAKI KURAYASU
IPC: H05K13/08
Filed: 1998-09-03
Abstract: PROBLEM TO BE SOLVED: To inhibit inertial force and impact force applied to a part sucked to a suction nozzle minimally because the acceleration of the rotation of a nozzle-rotation correction section is set at the irreducible minimal value of a demand in response to rotation-correction angles, to prevent a mounting mistake to an article to be mounted in the part and to improve yield. SOLUTION: Inertial force and impact force applied to electronic parts 1 sucked to suction nozzles 5 are suppressed minimally by minimally setting the acceleration of a nozzle-rotation correction section 13 calculated by a recognition result in a part recognition section 10 so that rotation is corrected within the time, when correction is enabled, of the suction nozzles 5 during temporary stoppage when the nozzle-rotation correction section 13 is turned and a rotation correction angle is obtained, the mounting mistake of the electronic parts 1 to a printed board 3 is prevented, and yield can be improved.

IPC: G01P5/00
Filed: 1986-10-20
Abstract: PURPOSE:To measure the flow velocity of underground water in a short period from variation in the intensity of light scattered by scattering particles in the underground water passing through diffraction fringes by forming the diffraction grating of a light source and a diffraction grating in a sensor probe. CONSTITUTION:A sensor probe 15 is fixed in a measurement section for the flow velocity of the underground water and a light source 20 is driven to emit laser light to the transmission type diffraction grating 21. The laser light is diffracted by passing through the grating 21 to generate diffracted light beams of plural order. The diffracted light 23 of a 0th order and diffracted light 24 of a 1st order among the diffracted light beams are converged by a reflecting mirror 22 on a specific intersection part 30 and the diffracted light beams 23 and 24 cross each other to form diffraction fringes at the intersection part 30. When a particle in the underground water passes in this interference fringes, scattered light is generated and photodetected by a condenser lens 25. Then, it is transmitted to an analysis part on the ground through an optical fiber 26 and the flow velocity of the underground water can be measured in a short period.

Abstract: PURPOSE:To display the high breakdown strength characteristics sufficient for circuit operation having super rapidity and low power consumption by a method wherein, within a heterojunction bipolar transistor, an emitter, a base, a collector layer are structured to make specific band gaps. CONSTITUTION:The title semiconductor device is provided with an n type layer 28, a p type base layer 26 making smaller band gap than that of the emitter layer 28, the first collector layer 24 making equal band gap to that of the base layer 26, the second collector layer 22 planar-doped in p-type and the third n-type collector layer 18 making the larger layer band gap than that of the first collector layer. Through these procedures, since the electric field in the first collector layer 24 is set up by the difference in the impurities of the base layer and the second collector layer, the running rate of the electrons injected from the base layer to the first collector layer is accelerated. Besides, the band gap of the third collector layer to be a high electric field by p-n junction becomes wider than that of the first collector layer furthermore, the band gap of the fourth collector layer becomes gradually wider. Accordingly, the occurrence of the avalanche effect can be avoided more securely.

Filed: 1995-09-27
Abstract: PROBLEM TO BE SOLVED: To reduce both a short-term and a long-term downward drift by a method wherein material is deposited on the surface of a substrate, and SiH4 gas is made to flow through a chamber for purging residual gas used in a deposition step. SOLUTION: Processing gas is introduced into a chamber 12 to deposit a tungsten silicide. It is preferable that a purge step is carried out by the use of dichlorosilane(DCS) for an optional part of the chamber after a deposition process is finished but before an SiH4 purge step is started. Thereafter, a feed valve 78 is opened to enable SiH4 to flow out from 6 gas source 74. SiH4 is sent to a plenum 42 and a chamber 12 from the gas source 74 through a field line 40 and a valve 52. A direct flow of SiH4 through the valve 52 is prevented from coming into contact with WF6 which may be left in a gas mixing assembly 16 and reacting on it.

Title: Production of boron nitride material
Inventor: OGAWA TAKASHI
IPC: C23C16/34
Filed: 1988-10-05
Abstract: PURPOSE:To prevent the clogging of a nozzle due to the deposition of B in the nozzle by mixing a specified amt. of an inert gas into a gaseous boron halide, and supplying the mixture to the nozzle at the time of forming pyrolyzed boron nitride from a gaseous boron halide and gaseous ammonia by the chemical vapor-phase reaction. CONSTITUTION:A Ti substrate 1 is placed in a heated reaction furnace. The mixture of the gaseous boron halide such as BCl3 and an inert gas such as Ar in the volume of 5-10 times that of the gaseous boron halide is introduced toward the substrate 1 from the injection port 5a of a graphite nozzle 3a, and gaseous NH3 is introduced from the injection port 5b of another graphite nozzle 3b. The BCl3 is allowed to react with the NH3 at >=1800 deg.C and <=5Torr pressure to form the thin film of the pyrolyzed BN on the substrate 1. Since the BCl3 mixed with the inert gas such as Ar is supplied to the BCl3 inlet nozzle 3a, the BCl3 is not reduced by the gaseous H2 formed by the decomposition of NH3 in the nozzle 3a, hence B7 is not deposited in the nozzle 3a, the nozzle 3a is not clogged, and the pyrolyzed BN film is stably formed.
