Title: Method for controlling flow of molten steel in mold in continuous casting
Inventor: KURATANI HIDEYA
IPC: B22D11/10
Filed: 1993-04-07
Abstract: PURPOSE:To obtain a good quality cast slab without developing casting defect by inspecting drift degree in molten steel in a mold, adjusting shifting of an immersion nozzle in the width direction of the mold based on the value of the drift degree and optionally controlling the horizontal balance of turn-over flow rate by collision of the discharged flow to a short wall side of the mold. CONSTITUTION:At first, at the time of shifting the immersion nozzle 3 positioned at the center part of the mold 1 to either one side of the short wall sides of the mold, the turn-over flow rate at the approached short wall side becomes relatively large and at the same time, the molten metal surface level at this position becomes relatively high. Therefore, by measuring at least one among the flow rates of two direction discharging flows from two molten steel discharging holes, molten steel temps. or mold temps. at both short wall sides and the molten metal surface levels at both short wall sides, the drift degree of the molten steel is inspected. Based on this measurement, by shifting the immersion nozzle 3 in the short wall side to the short wall side at a lower flow rate or at a lower temp. or to the short wall side of the lower molten metal surface level, the difference between the flows at the right and the left sides, i.e., the drift flow is canceled and the development of the casting defect can be prevented.

Abstract: PROBLEM TO BE SOLVED: To simplify a light-shading structure and to prevent occurrence of the disadvantage that the surroundings become bright due to light, by using a black light lamp for a light source, in a cleaning device purifying contaminants in air by a photocatalyst. SOLUTION: An optical deodorizing unit has a photocatalyst element 61 wherein the photocatalyst is borne by a honeycomb-shaped bearing body and a light source 51 which casts ultraviolet rays on this element. The light source 51 is a columnar straight tube type cold cathode fluorescent lamp. Herein the light source 51 is a black light lamp and the light emitted therefrom does not contain the light in a visible radiation region of a wavelength 400 nm or above almost at all, but contains mainly the light in an ultraviolet region. The wavelength thereof is distributed in the region of 350-410 nm, for instance. It is preferable, as the light source 51, that the light emitted therefrom contains the one in the ultraviolet region of which the wavelength is 320-400 nm.  The light of 400 nm or below activates the photocatalyst of TiO2 , ZnO or the like and can purify contaminants efficiently and, since the visible radiation region is not contained, it can be used even in the night without any hindrance.

Title: Device for producing sentence in chinese language
Inventor: OGURA HIDETAKA
IPC: G06F3/023
Filed: 1988-04-01
Abstract: PURPOSE:To reduce the capacity of a conversion dictionary and to efficiently produce a recursive interrogative sentence by performing batch conversion without recording the recursive interrogative sentence on the conversion dictionary. CONSTITUTION:When pin tone reading is inputted from a keyboard 20 and a conversion key is depressed, a CPU25 analyzes a rule for the pin tone reading, and judges whether or not it is the recursive interrogative sentence. The above judgement is performed in such a way that it is judged whether or not the pin tone reading consists of three syllables first, and when it is not the three syllables, it is judged as the a nonrecursive interrogative sentence. Next, it is checked whether or not the second pin tone reading of the three syllables is 'bu', and when it is not 'bu', it is judged as the nonrecursive interrogative sentence. Following that, when the pin tone reading of a second syllable in the three syllables is 'bu', it is checked whether or not the pin tone reading of a first syllable is equal to that of a third syllable, and when they are the same ones, it is judged as the recursive interrogative sentence. When the sentence is the interrogative sentence, the CPU25 retrieves the KANJI (Chinese character) of each syllable of a pin tone from a single KANJI dictionary 21 sequentially, and forms the recursive interrogative sentence, and it is displayed.
