A method and apparatus of cooling incinerator exhaust gas for a cleaning treatment of high temperature exhaust gas discharged from an incinerator of refuse and/or waste in a post-step are provided. A spray cooling chamber includes a chamber having a lower end portion formed into a nearly cylindrical shape of an inverted conical shape, a gas distribution chamber equipped with a revolving blade, arranged at an upstream side of the chamber, a sprayer of a cooling liquid arranged at central upper portion of the chamber, a dust exhaust port arranged at the lower end portion of the chamber, and an exhaust pipe arranged on the chamber. Waste heat recovery from exhaust gas is limited to a temperature range capable of suppressing generation of dioxins, and high temperature exhaust gas is rapidly cooled, particularly at a temperature drop rate such that the vicinity of 300.degree. C. is dropped in a short time within 1 second, so that exhaust concentration of dioxins from an incinerator plant can be decreased to 0.1 ng-TEQ/Nm.sup.3 or less.

Productivity of switching optical connections is improved significantly with the mechanical splice presented. A single fiber cable or a fiber tape, with the bare fiber exposed at the tip, is inserted from the terminal ends of an aligner element, and are clamped between a lid and a base member of the aligner element, A U-shaped spring clamp is coupled to the aligner element to secure the cables clamped in the aligner element. After the aligner element is closed and coupled into the spring clamp, wedge insertion openings provided in the front face of the aligner element enable to lift the lid member from the base member sufficiently to enable removal of one or both of the cables. The mechanical splice is constructed simply and ruggedly so that cables can be connected or disconnected manually by coupling the aligner element into or decoupling from the spring clamp. The external shape of the aligner is angular, and permits stable handling on workbench or with tools, thus leading to improved productivity in field installation as well as in assembly operations.

A frequency mixer circuit comprises a first differential circuit composed of first and second transistors having common-connected emitters, and a second differential circuit composed of third and fourth transistors having common-connected emitters. A collector of the first transistor is connected to a collector of the third transistor and also connected through a first resistor to Vcc. A collector of the second transistor is connected to a collector of the fourth transistor and also connected through a second resistor to Vcc. A base of the first transistor is connected to a base of the fourth transistor, and a base of the second transistor is connected to a base of the third transistor. An emitter-grounded, fifth transistor is connected at its collector to the common-connected emitters of the first and second transistors, so as to constitute a current source for driving the first differential circuit. An emitter-grounded, sixth transistor is connected at its collector to the common-connected emitters of the third and fourth transistors, so as to constitute a current source for driving the second differential circuit. The base of the first to fourth transistors are biased with a first bias voltage, and a first high frequency signal is applied in the form of an unbalanced signal to the base of the first and fourth transistors. The base of the fifth and sixth transistors are biased with a second bias voltage, and a second high frequency signal is applied in the form of an unbalanced signal to the base of the fifth transistor.

A film image reproducing apparatus for reproducing a film image of each frame of a film, includes: an image pick up device which picks up a film image; a reproducer which is operable to reproduce specified areas of the picked up film image; an information reader which reads information recorded on the film concerning the orientation of the film image; a reproducing direction designator which designates a reproducing direction of images in the areas; and a controller which controls the reproducer based on the read information and the designated reproducing direction so as to reproduce the image areas in the designated reproducing direction while keeping an image in each image area in a specified reference orientation irrespective of the direction of the film image on the film. This apparatus can constantly move an image in a designated direction regardless of the orientation of the film image.

A recording medium includes a transparent substrate and a recording layer formed thereon for recording information, and a component made of material with a large loss factor, such as butyl rubber, bond magnet, etc. By suppressing recording medium vibration resonance from a recording and reproducing device, an improved frequency characteristic of a linear motor can be achieved, thereby enabling high access speed. Preferably, the large-loss material also provides a directional magnetic field which facilitates magneto-optical rewriting on the recording layer.

Semiconductor chip manufacturing methods and devices are disclosed which store dicing data corresponding to the kinds of wafers, when data indicating the wafer kinds are input, read out the dicing data corresponding to the data input, and cut a wafer set at a given position to a desired shape in accordance with the dicing data to thereby manufacture a semiconductor chip. The manufacturing methods and devices include read means for inputting the data indicating the wafer kinds. According to the manufacturing method and device, a symbol indicating the kind of the wafer is recorded as an identification symbol readable by the read means and on a member moving together with the wafer in a chip manufacturing process that is not part of the product being manufactured, and preferably, is also not part of a recyclable carrier for the wafer to be diced. When the data indicating the kind of the wafer is input, the identification symbol recorded in the above-mentioned member is read out by the read means.

An interrogating device includes a memory for storing forward rules and facts, which are used in a forward inference control system, and a control unit operable to add or delete a fact to the memory. In this interrogating device, the accuracy indicates the probability degree of preparation for a conclusion section of the rule. The fact is added to the conclusion section of the rule and is stored in the memory. Also, the accuracy may be used in a strategy for a conflict resolution of a forward inference control. The fact for the accuracy that is obtained in the backward inference has a structure identical to the fact which the accuracy is added for use in the forward inference. By adding the accuracy negatively to the fact and the rule, an inference which uses uncertain data in the forward inference is possible.
摘要:
In order to indicate the operation of a parking brake of an automobile, a switching means responsive to the operation of the parking brake is disposed between the ignition switch and a power side terminal of the stop lights for indicating the braking of the automobile. The operation of the parking brake is thus indicated to the drivers of automobiles coming from behind, thereby preventing a collision from behind or the other accidents.
