Abstract: A method for growing a crystal of an Al-containing III-V group compound semiconductor by the conventional HVPE method, characterized in that it comprises a step of reacting Al with hydrogen halide at a temperature of 700° C. or lower to form a halide of Al. The method has allowed the suppression of the formation of aluminum chloride (AlCl) or aluminum bromide (AlBr) reacting violently with quartz, which is the material of a reaction vessel for the growth, resulting in the achievement of the vapor phase growth of an Al-containing III-V group compound semiconductor at a rate of 100 microns/hr or more, which has lead to the mass-production of a substrate and a semiconductor element having satisfactory resistance to adverse environment.

Abstract: A method and apparatus for performing field assembling (high precision alignment) work efficiently by eliminating any work miss in structural component assembling work where 180° turning state is expected and grasping the connecting/assembling posture (inclination) conditions of many components systematically in order to assist automation of assembling work of a structure and automatic crane control. A data sampling/recording (data logging) device for maintaining the assembled structure is also provided. The data includes vibration data on a multistory building at the time of an earthquake, deflection data on a vessel structure due to high waves, and the like. A state that the components of a structure are arranged to share common horizontal/vertical directions is the completed state of the structure.

Abstract: (Problems) A reaction container (apparatus) with a high efficiency, which can overcome problems of common chemically processing apparatuses using a solvent set where the compatible state and the separated state are reversibly changeable depending on a temperature, i.e. problems of the apparatus disclosed in Japanese Patent Application 2002-198242, namely the separation over time and spatial separation between compatible state and separated state. (Means for Solving the Problems) A temperature distribution is formed inside a reaction container, such that the temperature of one (optional) partial region inside the reaction container is the temperature for making first and second solvent solutions at a compatible state or a higher temperature, while the temperature of the other partial region is the temperature for making the solutions at a separated state or a lower temperature. Additionally, a reaction-promoting energy such as light and electricity is fed to the part at the compatible state.

Abstract: Plural movement/motion tracking regions on surfaces of an animal are determined based on movement/motion for quantifying (a first step). Coating including a dye or a fluorescent material is applied on the plural movement/motion tracking regions (a second step). An image of the organism are captured under light irradiation (especially under irradiation of an ultraviolet ray for nocturnal animals) (a third step). In the captured image, plural marking areas are discriminated, and representative point locations of the marking areas are decided (a fourth step). A fifth step is carried out for determining the specific movement/motion based on plural representative point location data and for outputting them. A computer apparatus is configured for executing these steps.

Abstract: A continuous thin metal strip formed by quenching on a single quenching roll is separated from the quenching roll and conveyed along a fly path to a coiling system directly or via pinch rolls. The path along which the thin metal strip flies is stabilized by a jet of a fluid jetted from a slit and biased to flow along a convex curved surface, whereby the time until the strip is taken up or nipped by the pinch rolls is shortened.

Abstract: A method and apparatus are disclosed for controlling a physical property such as deposited film thickness to a desired value of control in a high temperature process using a desired emissivity power ratio and an emissivity power ratio measured from detected radiation energy. The measured emissivity power ratio is obtained on-line from detection signals of radiation sensors. A desired value of control is converted to the desired emissivity power ratio using predetermined relationships established by theory or experiment. The desired emissivity power ratio and the measured emissivity power ratio are compared to achieve the desired value of control.

Abstract: Radiated light with a specified wavelength from a material is detected and a first parameter corresponding to the emissivity ratio is obtained from the plurality of detection signals. Since the emissivity takes on different values according to the condition of the surface of the material, the first parameter changes depending on the surface condition of the material. There is a correlation between a physical value indicating a condition of the material surface and the first parameter. The correlation remains equivalent even if a second parameter corresponding to the physical value is used instead of the physical value itself (for example, an optical physical value such as reflectivity and absorptivity, the thickness of a film formed on the material surface, the surface roughness, and the degree of galvannealing). As an example of the parameter corresponding to the physical value, there is the logarithmic ratio between emissivities (ln .epsilon..sub.a /ln .epsilon..sub.

Abstract: A system and method for automatically and optimally determining a route to be wired in a Programmable Logic Device (PLD) are disclosed in which a plurality of load pins to be wired with a source pin are selected sequentially according to a shortest length of distance from the source pin to the respective load pins, a plurality of switching stations present midway through each route of paths are selected on the basis of coordinates of a center of gravity derived from the coordinates of the unwired load pins and distances to the respective load pins to be wired sequentially, and, thus, a line network constituted by the routes of the first and second paths is formed. Furthermore, the route is corrected by searching out any of problematic switching stations through which the path cannot be formed from among the switching stations present along the route so as to bypass the problematic switching station.

Abstract: An apparatus for separating fibers from a fiber aggregate comprises a hollow cylindrical apparatus housing defining therein a dissolving chamber. A partition is disposed in the internal space of the apparatus housing and forms the bottom of the dissolving chamber. The partition defines a plurality of through openings, through which fibers separated from the aggregate passes. The apparatus housing has an aggregate inlet to introduce the aggregate to be dissolved with pressurized air. The pressurized air carrying the aggregates is discharged toward the partition and forms swirl flow in the dissolving chamber. By the swirl flow of the air, the aggregate flows to collide onto the partition with an impact. This impact serves as an energy for causing dispersion or dissolving of the aggregate. The partition is preferably formed with elastically or resiliently deformable material for absorbing impact upon the collision of the aggregate thereonto so as not to cause destroying of each individual fiber.

Abstract: A spiral gas stream is generated in a pipeline when a uniform flow of gas flowing in a cylinder having inner diameter larger than that of the pipeline is introduced through a funnelform reducer into the inlet of the pipeline and bringing the mean gas stream velocity in the pipeline faster than 20 meter per second. The uniform flow of gas is formed in the cylinder easily when outside low pressure gas is fed into the cylinder through a feed gas inlet pipe installed diagonally at the side of the cylinder apart from the bottom plate so as to make the flow line of the feed gas to cross the axis of the cylinder and inclined toward the bottom plate. When solid particles are introduced into the spiral gas stream zone, they are transported to the outlet of the pipeline. As the compressed gas layer is formed along the inside wall of the pipeline by the spiral motion of gas stream, solid particles don't contact directly with the inside wall of the pipeline and don't hurt it.
