Title: Pretreatment of molten iron and equipment therefor
Inventor: NOGUCHI KATSUHIRO
IPC: C21C1/00
Filed: 1987-12-03
Abstract: PURPOSE:To prerefine molten iron in a short time by dipping both dip pipes of an inverted U-shaped vacuum vessel into the molten iron in an iron ladle to vacuum-suck the molten iron, circulating the molten iron with an inert gas from an injection lance, and simultaneously adding a pretreating agent to the molten iron in the vacuum vessel. CONSTITUTION:Molten iron 5 is charged into the iron ladle 2 closed by a ladle lid 3, and the ascending molten iron dip pipe 1a and descending molten iron dip pipe 1b of the inverted U-shaped vacuum vessel 1 fixed to the ladle lid 3 are dipped in the molten iron 5. The inside of the vacuum vessel 1 is evacuated by a vacuum pump 7, and the molten iron 5 is sucked up into the vacuum vessel 1. An inert gas such as N2 is blown into the molten iron from a lance 6 dipped in the molten iron 5, the molten iron 5 is drawn up by the ascending gas bubbles into the vacuum vessel 1 from the ascending molten iron pipe 1a, allowed to descend through the descending molten iron pipe 1b, and circulated between the vacuum vessel 1 and the iron ladle 2. The pretreating agents 13c such as a desulfurizing agent and a dephosphorizing agent are simultaneously added to the molten iron in the vacuum vessel 1 from a tank 13a, the pretreating agents 13c are sufficiently mixed with the molten iron 5 by the circulation, and the molten iron is rapidly desulfurized and dephosphorized.

IPC: G06T11/60
Filed: 1987-12-03
Abstract: PURPOSE:To realize reference to a document information covering plural pages at a glance and to realize the economical output of received documents by reducing the received document information and performing the output of the document information equivalent to plural pages in a single page. CONSTITUTION:The mixed document data including body picture and document data and received by a communication part 8 is sent to a RAM 12-2. The document data (character string data) among the mixed document data undergoes the pattern evolution via the character pattern data stored in a ROM 12-1 and is stored in a picture memory 14. While the image data is sent to a compression/expansion part 15 to undergo the expansion and is stored in the memory 14. Then the picture data stored in the memory 14 is reduced down to 1/(2Xnumber pages) via a reduction/magnification part 13. Thus the reduced picture data equivalent to all pages is displayed at a display part 1 and also outputted through a picture information output part 5 of a printer, etc.

IPC: H03F3/68
Filed: 1987-12-01
Abstract: PURPOSE:To prevent excess through current directly flowing to a ground from a power amplification source without passing a load by delaying a time when a second transistor for driving can be operated from a time when a first transistor for driving can be operated with the aid of a delay circuit. CONSTITUTION:The delay circuit consisting of a capacitor 18 is added to the base circuit of a transistor 15 for switching. Therefore, the transistor 16 is kept being turn-on until the capacitor 18 is discharged after a function stopping signal 11 is changed from a high level to a low level. The transistor 15 is made to be turned off when the capacitor 18 is discharged soon after and the transistor 10 for driving is made to be a state that it can be operated. Then, at this time, the driving circuit of the transistor 9 for driving is sufficiently settled. Thus, the excess through current flowing to the ground from the power amplification source 8 can be prevented.

Title: Lattice-shaped reinforcing base material and manufacture thereof and board based on their application
Inventor: IKEDA TOSHIO
IPC: D04H3/045
Filed: 1994-11-16
Abstract: PURPOSE: To make it possible to impregnate high viscosity matrices by laying out a rod which crosses a bundle of vertical reinforcement fibers in the shape of a lattice at the middle position of a twisting intersection and expanding the intersection between the bundle of the vertical reinforcement fibers and the rod. CONSTITUTION: Rods 9, which cross bundles of fibers 10 at right angles, are laid out in the shape of a lattice with a spacing at the intersections 14 located at the middle position of twisted intersections which are adjacent with a pair of vertical reinforcement bundles 10, which are installed by plurals in parallel to each other with a spacing and twisted by an integer times 180 deg. reversely by turns in a lattice-shaped reinforcing base material 11 and the intersections 14 are expanded. Upper and lower reinforcing layers 16 and 17 are laid out where the reinforcing base material 11 is loaded on the reinforcing layer 17, thereby filling up resin concrete 18 between the reinforcing layers 16 and 17, and pressure molding and forming a board-like member 19.  Since the intersections 14 are expanded, the reinforcing base material comes in direct contact with the reinforcing layer 17 only at the intersections 14, which makes it possible to hold a clearance between the flat reinforcing layers 17 and impregnate the high viscosity resin concrete 18 when it is used.

Filed: 1995-11-24
Abstract: PROBLEM TO BE SOLVED: To provide an automatic vending machine which has a carrier device on its own partition wall to eliminate an individual space needed for the carrier device and also can carry the commodities to a cooking room from a storage room in a short time. SOLUTION: When a commodity A is received by a receiving plate 110 and the plate 110 is inverted, every holding plate 112 moves in its holding direction to holds the commodity A that is kept on the plate 110. The plate 110 is inverted in such a commodity holding state, and the commodity A is moved to a cooking room from the plate 110. Every plate 112 moves in its holding cancel direction to cancel the holding state of the commodity A right before the end of inversion of the plate 110. Thus the commodity A drops from the plate 110 and is stored in the cooking room.

Abstract: PURPOSE:To eliminate adverse effect to the operation of a signal processing system circuit and to improve an S/N ratio by providing an absorbing region for absorbing carriers, which leak out of a photosensor, between the photosensor and a signal processing element. CONSTITUTION:Carriers 110, which are generated by a light 109' to reach a p-type semiconductor substrate 104 out of incident lights 109 to be incided in a photo diode 101 through the opening part of an oxide film 111 and leak out of the photo diode 101, are absorbed in an N<-> epitaxial layer 106 by a drift due to the inverse bias of an absorbing region 103 consisting of a diode constituted of the substrate 104 and an N-type epitaxial layer 106. Thereby, as the carriers 110, which leak out of the photo diode 101, do not reach up to a signal processing bipolar element 102, adverse effect is never exerted on the operation of a signal processing system circuit and the deterioration of an S/N ratio is prevented.

Al is grown in the grooves 13, 14 in the semiconductor substrate 11 having the pattern; after that, the mask layer 12 is removed; and Al films 15, 16 are formed. In addition, the semiconductor substrate 11 is etched and treated by making use of the Al films 15, 16 as a mask; and opening parts having different depths are formed in the semiconductor substrate by the difference in an etching rate between the metal film and the semiconductor substrate. Thereby, many grooves 13, 14 whose depth is different can be formed in arbitrary parts on the semiconductor substrate 11 by executing one dry etching operation.
