Title: Device for peeling off surface layer of inorganic material
Inventor: DOI AKIRA
IPC: G21F9/28
Filed: 1997-11-11
Abstract: PROBLEM TO BE SOLVED: To efficiently collect the dust which is produced at the time when the surface of concrete is peeled off with a simple structure. SOLUTION: The surface layer of concrete is melted by irradiating the surface layer with high-output laser light from a laser head 3. Then, after the surface layer is solidified, the solidified layer (b) is removed by moving a peeling-off section 8 which is incorporated in a vibrating device 6 and vibrated by means of ultrasonic waves on the surface of the solidified layer 8 at a low speed while the section 8 is brought into contact with the layer (b). The dust which is produced when the solidified layer (b) is removed is collected in the section 8 by sucking air through voids 8a and 8b.

Abstract: PROBLEM TO BE SOLVED: To enable the projecting or the recessed three-dimensional engraving of a three-dimensional matter such as a coin in a short time through a simple operation by converting data on a three-dimensional shape obtained by a three-dimensional instrument from an object to be photographed such as a man positioned in front of a casing, to data dedicated for an automatic three-dimensional engraving machine. SOLUTION: First money is deposited into the automatic three-dimensional engraving device 22 by a man sitting on a chair 5 and a three-dimensional instrument actuating switch 19 is switched ON. Then three-dimensional shape data on the upper half region of a body of the man sitting on the chair 5 as an object to be photographed is displayed on a monitor 8 after the measurement of the object in the non-contact mode by a laser three-dimensional instrument 6 using a laser beam which is housed in an upper casing 4. When the man is satisfied with an image displayed on the monitor 8, he depresses an OK switch 21 to convert the three-dimensional shape data to data dedicated for the automatic three-dimensional engraving machine with the help of a data conversion soft ware 10.  Finally a manipulator 11 is actuated to pick up a three-dimensional matter to be engraved such as a coin from a three-dimensional engraved matter supply mechanism 13 and supplies the three-dimensional matter to be engraved to the automatic three-dimensional engraving machine 9.

Title: Method and device for reducing bus arbitration waiting time
Inventor: FUREDERITSUKU EMU SERAUSUKIIZU
IPC: G06F13/36
Filed: 1996-11-07
Abstract: PROBLEM TO BE SOLVED: To reduce arbitration waiting time by switching an arbitration to a high speed or a low speed arbitration according to the number of device requesting the access to a bus. SOLUTION: A processor 22, an input/output unit 23 and a DMA 24 are connected with a shared bus 27. These devices 22 to 24 are provided with lines of the same number and are connected with an arbitration bus 21. A duplex arbitration unit 20 has two arbitration modes. In a high speed mode, a device sharing the bus is capable of simultaneously requesting the access to the bus and the driving of the bus. Therefore, when only a device drives the bus, waiting time is not generated. When plural devices drive the bus, a speed mode is switched to a low speed mode/arbitration, a winnder is determined, the packets imparted to plural drivers are made invalid and the bus is driven by the next cycle. Therefore, the arbitration is not delayed in also the low speed mode.

Abstract: PURPOSE:To produce hollow pellets of iron ore for a blast furnace having an excellent reducing property by subjecting green pellets made into two-layered structure in which the inner shell is formed to the m.p. lower than the m.p. of the outer shell by adjusting the content of CaO to calcination at the temp. between the m.p. of both. CONSTITUTION:The fine iron ore and CaO fed out of a raw material tank 6 for the internal shell are mixed together with binder such as bentonite and water in a mixer 7 and are then pelletized by a pelletizer 8, by which the pellets for the inner shell are obtd. On the other hand, the fine iron ore and CaO fed out of a raw material tank 9 for the outer shell are mixed together with the binder and are charged into a pelletizer 11, by which the green pellets having the two-layered structure consisting of the inner shell 1 and the outer shell 2 are obtd. The content of CaO is adjusted at this time so that the m.p. of the inner shell 1 is lower than the m.p. of the outer shell 2. The above-mentioned green pellets are then calcined at the temp. between the m.p. of the inner shell 1 and the m.p. of the outer shell 2. The inner shell 1 is thereby melted and is penetrated into the inside part 3 of the outer shell 2 to form a cavity 4. The hollow pellets 5 of the iron ore are thus obtd.
