Title: Melting method for ferruginous cold charge
Inventor: KUWABARA TATSURO
IPC: C21C5/28
Filed: 1988-01-29
Abstract: PURPOSE:To prevent contamination of a molten iron by a sulfur component and to suppress erosion of lining refractories by operating the supply rate of auxiliary materials to maintain the basicity prior to tapping in a specific range at the time of melting a ferruginous cold charge and forming the high-C molten iron. CONSTITUTION:The ferruginous cold charge such as scrap, cold pig and iron ore as well as a carbonaceous material, auxiliary materials and oxygen are supplied into a converter which is made of a basic refractory lining structure and in which a seed hot metal exists. The ferruginous cold charge is melted in said converter and the high-C molten iron is obtd. The basicity prior to tapping is adjusted to 1.1-1.4 by operating the supply rate of the auxiliary materials such as quicklime, limestone, soft-burned dolomite, green dolomite, and fluorite. The contamination of the molten iron by the sulfur component of the molten iron is thereby suppressed and the erosion of the refractories at the time of tapping is decreased without making the special coating operation. Slag discharge is executed without discharging the seed hot metal.

Title: Tool drive unit for machine tool
Inventor: YASUGATA KAZUHIRO
IPC: B23Q5/027
Filed: 1988-01-29
Abstract: PURPOSE:To reduce the occurrence of noise and secure machining ability in a simple structure with an electric drive force by integrally providing super conductive shaft areas at both ends of the shaft of a tool fixing jig, and having them supported by bearings, so that an electric current is switched to flow to magnetic field generating coils which are fitted to the bearings. CONSTITUTION:When an electric current flows to a right-side magnetic field generating coil 20 while a left-side coil 20 is shut off, a magnetic field is generated in the right-side coil 20 where the electric current flows, so as to affect a super conductive shaft area 14 on the same side, and a driving force is generated in the shaft area 14 in axial direction, so that a jig shaft 1 is driven left according to an electric current flowing direction. And as the left-side coil 20 is shut off, it only slides. And then, when the shaft area 14 reaches the bottom area of a left-side bearing 16, it confronts a permanent magnet 18 therein, and a minus effect is generated between magnetic lines of force from the magnet 18 and the shaft area 14, so that the shaft 12 stops without the collision of the shaft area 14 against the magnet 18. Consequently, the shaft 12 which is shifted in axial direction by means of the driving force of the right-side coil 20, stops due to the influence of the left-side magnet 18, so that the stroke quantity of the shaft 12 can be determined. And also, as the right and left alternate flows of the electric current result in the continuous reciprocation of the shaft 12, a work 26 can be ground with a grinding tool 10.

Abstract: PURPOSE:To increase a heating surface area for the improvement of heat efficiency, by allowing a combustion gas to pass along the outer and inner wall surface of heat-exchanging fluid chamber, in a heat exchanger adapted to recirculate the combustion gas. CONSTITUTION:A part of combustion gas flows along the inner wall surface 2a of a burner to undergo a heat exchange with the water of heat-exchanging fluid chamber 4. Then, the combustion gas passes through a clearance at the attaching port 2b of flame retaining section, reaches a circulating flow inlet 16 and is withdrawn into a mixing pipe 20 under a negative pressure caused by a high velosity vortex air stream. The remaining part of combustion gas enters into a channel 6 via an opening 21 defined through inner and outer wall surfaces 2a, 2b of boiler and further passes along the outer wall surface 2b of boiler. The combustion gas has its heat exchanged with the water of fluid chamber 4 and is withdrawn into the mixing pipe under a withdrawing action taking place at the inlet 16. The recirculated combustion gas serves to heat up the mixture of kerosene grains and air to establish a gasification or its approximate combustion state of producing a blue burning flame.

IPC: G11B15/087
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To surely shift the fast forward reproducing state into the normal reproducing state when a sectional period between a CM(commercial message) and real program is detected at the fast forward reproducing time. SOLUTION: When it is detected that an operating key 5 is pressed down under the normal reproducing state by the user, a command for shifting the reproducing state into the fast forward reproducing state is given to a driving mechanism 2 by a driving control part 3, while measurement of the CM in length is commenced by a contents period timer 7, and also the length of the latest sectional period is read out of a storage circuit 4 to set a sectional period threshold. Then, when the sectional period between the CM and the real program is detected under the fast forward reproducing state, a command for shifting this state into the normal reproducing state is issued by the driving control part 3. When a measuring value by the contents period timer 7 exceeds a prescribed CM period threshold, the command for shifting into the normal reproducing state is similarly issued as well.
