Title: M13 time division multiplex system
Inventor: IGA NAOTO
IPC: H04J3/04
Filed: 1995-04-27
Abstract: PURPOSE: To reduce the number of connection lines by connecting each information line of the time division multiplex system to each M12 section in common and sending DS3 data comprising information bits only from each M12 section to an M23 section via the same connection line with different timings. CONSTITUTION: A DS1→DS2 multiplexer section 102 of an M12 section 101 applies 4-multiplexing to DS1 data to generate DS2 data. A DS3 frame counter section 103 processes the DS data generated by the multiplexer section 102 with a data width of DS3 data based on a DS3 clock, a DS3 frame pulse and a DS3 destuff pulse from an M23 section 104. Furthermore, each M12 section 101 decides a timing of an output of the DS3 data from each M12 section 101 in response to a count of the counter 103 corresponding to SLOT-ID relating to a slot inserted in each M12 section 101 and a command given from a common back board. Thus, the data are processed by four connection lines.

Abstract: PURPOSE:To extend the service life of reconditioned molding sand in the stage of casting a casting with a casting mold divided to upper and lower parts by removing the molten metal in the sprue provided to a cope to eliminate the molding sand to be stuck to the sprue in the stage of dividing the casting mold and taking out the casting. CONSTITUTION:Two casting spaces 14 are formed in the divided casting mold 1 consisting of the cope 2 and drag 3 and are connected by a horizontal runner 11. The funnel-shaped sprue 13 provided to the cope 2 and the vertical runner 12 continuous therewith are connected to the runner 11. The molten metal is poured through the spure 13 and is cast into the spaces 14 through the runner 12 and the runner 11. The molten metal accumulated in the sprue 13 is dipped by rotating a molten metal ladling member 28 provided to a molten metal ladling device 20 around a turning shaft 27 before the molten metal in the sprue 13 solidifies. There is no solidified metal in the sprue 13 in the case of detaching the cope 2 from the drag 2 after solidification and therefore there is no molding sand sticking thereto. The mixing of the molding sand and core sand is thus obviated, by which the number of reusing the molding sand and core sand is increased.

Abstract: PURPOSE:To prevent a reversal flow of exhaust gas by providing a fuel mixing section having a burner head at one end and multiple conduits, disposing a plurality of nozzles which can independently inject fuel into a fuel injection chamber, and disposing a valve in the fuel mixing section which opens or closes the conduits. CONSTITUTION:When the burning is to be performed with only the nozzle 8B injecting fuel, the handle 11 of an open/close valve 14 is operated to rotate a rotary spool 10 and a drive shaft 12 to close off a conduit inlet 5A with a valve head 13, and fuel is supplied to the nozzle 8B. Fuel is injected from the nozzle 8B, and the injected fuel is mixed with air supplied from an air feed port 3 in a conduit 4B to be burnt at a burner head 6B.
