Filed: 1989-03-15
Abstract: PURPOSE:To effect an efficient ventilation by providing a waste water inlet through which to permit the waste water to flow into a treating tank while changing the level of the waste water therein. CONSTITUTION:When a waste water transfer pump 10 is actuated to transfer waste water 4 from a treating tank 1 into a secondary tank 9, outside air is brought in the treating tank 1 through a ventilation duct 2, since a negative pressure is created due to a space made larger above the surface of the waste water 4 in the treating tank 1. When the waste water is allowed to flow into the treating tank 1 from a waste water inlet 3 in an amt. larger than that of the waste water 4 which has been transferred by the pump 10, the level of the waste water 4 in the treating tank 1 is raised, a space above the surface of the waste water 4 being made smaller, In doing so, the treating tank 1 is closed to expel malodorous air outside through the ventilation duct 2. Therefore, the odor can be efficiently driven out.

Title: Method of melting bump, melting apparatus and method of producing semiconductor device
Inventor: TSUMURA KIYOAKI
IPC: H05B6/14
Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To omit the steps of flux coating of a bonding agent, reflowing, cleaning and drying without forming an oxide film on a bump, by heating and melting the bump formed on a substrate using an induction heating coil causing electromagnetic induction under oxygen atmosphere at a low concentration. SOLUTION: A gas inlet 18a is formed outside a substrate clamp 18, a mixed gas of non-oxidizng nitrogen and hydrogen is supplied from the gas inlet 18a. High frequency current flows through an induction heating coil 41, resistance loss occurred by eddy current causes heat from within solder. Since the atmosphere is non-oxidizing, the solder becomes a spherical shape by surface tension without forming an oxide film thereon even if flux is not used. Even if arrangement of solder bumps on the substrate is varied dependent on articles, the steps of flux coating, reflowing, cleaning and drying can be omitted and productivity can be improved independent of bump arrangement of processed objects by simply forming the induction heating coil in the shape of a hairpin, and moving it to heating the bump.

Title: Moving device for side guide roller provided right under casting mold of continuous casting machine
Inventor: TANIGUCHI TETSUO
IPC: B22D11/128
Filed: 1984-04-02
Abstract: PURPOSE:To move adequately side rollers without exerting excessive force to shells by emitting a stop command for a driving motor to a control valve when a voltage drops below a reference voltage. CONSTITUTION:Screw shafts 4 are rotated and the side guide rollers 1 are moved horizontally toward the shell 2 side when the control valve 6 is opened and air is supplied to the driving motor 5. An air motor 8 runs during this time to generate a voltage in a tachogenerator 9. The voltage is impressed to a comparator 10 and is compared by a reference voltage. When the voltage attains equal to the reference voltage, a close signal is fed from a comparator 10 to the valve 6 which in turn stops the revolution of the motor 5, thus stopping the movement of the rollers 1. The extent of the movement of the rolls 1 in this stage corresponds to the extent of changing the width of a billet and therefore the rollers 1 are adequately pressed to the shells 2 without exertion of excessive force thereto.

Abstract: PURPOSE:To read a character such as manuscript Kanji(Chinese character) or the like with high accuracy by allowing a character similar to the shape of an input character in order to be outputted from a character recognizer and using an index of a word dictionary and link information so as to attain collation of words. CONSTITUTION:A scanning section 20 scans a character on a document by a command of a common control section 10 and transfers a picture signal to a recognizing section 30. The recognizing section 30 calculates the similarily between the shape of the input character and the standard shape of character of each character and outputs a code of plural candidate characters to a word collating section 60 in the order of higher similarity. The collating section 60 combines the candidates stored in a collating order table storage section 40 so as to check whether or not the candidate character code string corresponding to the combination exists in a word dictionary storage section 50, and when the string exists, the section 60 outputs the character code string to an output line 64. When the string does not exist, the similar processing is repeated according to the order of the collation order table.
