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.

Method of and apparatus for conveying and guiding thin metal strip

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.

Method and apparatus for process control of material emitting radiation

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.b) corresponding to the temperature in the vicinity of the surface. Therefore, a second parameter can be obtained on the basis of the correlation and a physical value can be obtained. When the emissivity or logarithmic emissivity ratio is used as the second parameter, the temperature in the vicinity of the material surface can be obtained from the second parameter and the plurality of detection signals.

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. If this correction proves impossible, a second correction is sought by searching the problematic switching station itself so as to bypass a wired path present within the problematic switching station. If this correction also fails, a third mode of correction is implemented in which a switching station adjacent the problematic switching station is utilized.

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. Further preferably, a contact plate is suspended on the elastically or resiliently deformable partition. The contact plate opposes the aggregate inlet so that the aggregate introduced into the dissolving chamber will collide onto the contact plate.

Apparatus for separating fiber from fiber aggregate

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. As the center part of the cross section of the pipeline becomes very low pressure, especially along the axis of the pipeline, solid particles containing or accompanying volatile matters are desiccated or concentrated as a result of the evaporation of volatile matters while being transported in the pipeline. Solid particles deposited on the bottom of water can be dredged and dehydrated by the spiral gas stream transportation system. When solid particles transported by spiral gas stream in two or more pipelines are arranged to collide with mutually, pulverized fine solid particles are recovered. A chemical reaction which can not or hardly to proceed at normal temperature and pressure is promoted in a spiral gas stream zone.
