IPC: G06Q10/04
Filed: 1991-05-31
Abstract: PURPOSE:To effectively predict the temperature drop of molten steel in a ladle by learning in advance a correction value from a difference between an actual result value and a predictor in every ladle, and correcting the predictor by its correction value at the time of using the same ladle in the next time. CONSTITUTION:Surface temperature of a refractory and a shell is measured by using a radiation thermometer, etc., and with regard to plural charges, its temperature is measured repeatedly and recorded. As a result, based on a relation of a surface temperature of an inner wall of a vessel refractory determined based on collected data, thickness of the vessel refractory, and whether covering is executed or not after the vessel becomes empty after pouring is finished, an internal temperature distribution of the vessel refractory is derived from the measured inner wall surface temperature of the vessel refractory. Subsequently, by deriving an average temperature of the vessel refractory, based on this temperature distribution, a heat accumulation amount of the refractory and a heat removing amount by the vessel which is being carried are estimated. Accordingly, by learning the heat accumulation amount of every vessel, and executing a correction by using result of learning at the time of deciding the heat accumulation amount of the vessel in the next time, the prediction of high accuracy can be executed.

Title: Apparatus and method of photo-etching
Inventor: SHINOHARA KEIJI
IPC: H01L21/302
Filed: 1988-05-27
Abstract: PURPOSE:To easily obtain an anisotropic shape by etching without damaging a material to be etched by cooling a board and irradiating it with light for its photo-etching. CONSTITUTION:A board 1 to be treated is secured to a board holder, the holder is evacuated in vacuum, and chlorine gas is introduced from a gas inlet 41. The temperature of the holder of cooling means 2 is lowered, and a light of ultraviolet ray band is radiated from a light source 31. The gas is optically decomposed by the radiation of the light to generate chlorine radical, which reacts with polysilicon not covered with the resist 12 of a board 11 to excite a part Ia in which the light 3 is radiated, and SiClx of reactive product is easily separated. In the part Ib in which the light 3 is not radiated, even if the radical is reacted with the polysilicon, it is low temperature. Since energy of the radiation of the light is not applied thereto, the SiClx is not separated to operate as one type of sidewall protective film, thereby obtaining an anisotropically etching shape.

Abstract: PURPOSE:To simplify the mechanism, and reduce a stroke of movement, and eliminate the bad influence of vacuum sealing, and furthermore, make the direction of a film free by carrying a film cassette with rotary movement. CONSTITUTION:At the time of photographing, a film cassette is placed on a carrying case from a feeding magazine, and an arm 21 is rotated by a driving means around of a rotary shaft 27, drawing a circular orbit, to set the film cassette at the photographing position of a photographing chamber.

Title: Bed tilting apparatus for car
Inventor: YUKI HIROTAKA
IPC: B60P1/16
Filed: 1985-06-18
Abstract: PURPOSE:To obtain a compact apparatus by installing the second cylinder for tilting a bed by a prescribed angle to the first cylinder side of the bed pivotal installation point on a frame, thus increasing the arm of the operation line of the first cylinder and reducing the thrust force. CONSTITUTION:When the load W on a bed 1 is over a prescribed value, said bed 1 is tilted by a prescribed angle theta through a cylinder 8 by extending a hydraulic cylinder 7. Since the arm Q of the operation line M is large, the necessary thrust P of the second hydraulic cylinder 7 is small. Then, the bed 1 is tilted by extending the first hydraulic cylinder 4. The arm l' of the opera tion line L' of the thrust T4t becomes relatively large, since the bed 1 is tilted by a prescribed angle theta. Since the thrust T' becomes relatively small, the first cylinder 4 can be made compact. Therefore, layout can be made advanta geous, and cost cut is permitted.
