Title: Method and apparatus for manufacturing melted metal for cast iron
Inventor: HIRANO HARUYOSHI
IPC: F27B7/12
Filed: 1994-04-28
Abstract: PURPOSE:To provide a method and an apparatus for manufacturing melted metal for cast iron in which the saving of fuel and oxygen gas and the reduction in the oxygen content of the melted metal are realized by regulating a burning time or a flow rate ratio of the fuel to the oxygen gas to meet a melted state presumed from the variation in predetermined gas component in burning gas. CONSTITUTION:When the variation in a predetermined component content (e.g. CO gas concentration) during burning is detected by a CO gas sensor 7 by using a rotary melting furnace 1, the flow rate of the oxygen gas to be blown to a body 2 is reduced to be switched from an oxidation atmosphere burning to a reducing atmosphere burning. Thus, various types of unnecessary impurities are oxidized to be reduced, and the oxygen content of the melted metal can be reduced by the later reducing atmosphere burning. Continuation of burning for melting despite the completion of melting a raw material can be avoided.

Title: Magnetic recording medium
Inventor: AOYAMA AKIRA
IPC: G11B5/738
Filed: 1989-04-11
Abstract: PURPOSE:To obtain a magnetic recording medium having high coercive force and high S/N by forming a Co-Ni-Cr-Zr magnetic film and specifying the amt. of Zr to <=5at.%. CONSTITUTION:The magnetic recording medium consists of a magnetic film formed on a nonmagnetic substrate with a Cr base film interposed, and the magnetic film consists of Co-Ni-Cr-Zr with the amt. of Zr added by <=5at.%. By adding only a small amt. of Zr, S/N is largely improved. However, if Zr exceeds 5at.%, S/N becomes worse compared to a medium containing no Zr because of signal reduction. Therefore, the amt. of Zr is preferably <=5at.%. Thus, the magnetic characteristics and electromagnetic conversion characteristics of the Co-Ni-Cr-Zr film can be largely improved.

IPC: H01M50/528
Filed: 1991-03-28
Abstract: PURPOSE:To prevent generation of a short-circuit due to a protrusion in a collecting plate by providing a foaming resin film in a non-foaming condition in a surface of the collecting plate opposed to an element cell. CONSTITUTION:A foaming resin film 5 is laminated in a non-foaming condition on a surface of a collecting plate 4 opposed to an element cell, and after a protrusion 8 of the plate 11 is connected to a pole plate of the element cell, the film 5 is foamed and expanded between the element cell and the plate 4. Since a space between the element cell and the plate 4 is filled with foamed synthetic resin, even when an interpole earth piece temporarily falls off, a short-circuit is prevented from being generated. That is, the plate 4 is insulated from an interpole plate, and the short-circuit, which is a fatal defect of the element cell, between the plate 4 and the pole plate can be almost clearly eliminated. Since the non-foaming film 5 is provided in the plate 4 and foamed after connecting the plate 4 to the pole plate, the pole plate can be easily connected to the plate 4 similarly to the past and also foaming between the plate 4 and the pole plate to provide complete isolation thereof by the inflated synthetic resin, so that insulation can be effectively attained.

Title: Insulating material for impregnation
Inventor: ITO TATSUYA
IPC: H01B3/20
Filed: 1989-04-11
Abstract: PURPOSE:To obtain an insulating material for impregnation having sufficiently low swelling characteristics with a single material by constituting of specific poly-4-methylpentene-1. CONSTITUTION:Poly-4 methylpentene-1(PMP) wherein the isotactic index is 93% or more and the melt flow index is 5 to 120g/10min is used. Although a olefin (ethylene, butene, hexene, decene etc.) comonomer other than 4-methyl-1- pentene may be contained, the content is preferably 5mol.% or lower based on PMP for obtaining good electric characteristics and resistance to oil. Thus the obtained material is small in swelling ratio and high in breakdown voltage so that characteristics of low swelling property can be exhibited even if an insulation layer is constituted of a single material.

Title: Bus heater
Inventor: KANASHIKI SUSUMU
IPC: B60H1/08
Filed: 1983-05-25
Abstract: PURPOSE:To effectively utilize the engine cooling heat, improve the heating effect, and save energy in a large bus by providing a subradiator between a traveling engine cooling water outlet and a hot water boiler. CONSTITUTION:When the heating is used, the cooling water depriving an engine 1 of its heat discharges the heat into a room while passing a sub-radiator 9 and a defroster 8, and the inlet water temperature of a hot water boiler 6 is lowered. Here, the heat radiation quantity upstream the boiler 6 is made equal to that downstream, e.g., 11,024kcal/H is assumed to be radiated at the upstream side and the downstream side respectively, then the inlet water temperature of the boiler 6 becomes 65.8 deg.C, lower by 9.2 deg.C than the outlet side water temperature of the engine 1 of 75 deg.C. Therefore, if 11,024kcal/H is added by the boiler 6, the inlet water temperature of a main radiator 7 becomes 75 deg.C, equal to the outlet side water temperature of the engine 1; then 11,024kcal/H is radiated by the main radiator 7 to lower the water temperature by 9.2 deg.C, and the water of 65.8 deg.C flows into the engine 1. Thereby, an increase in capability when the hot water boiler is used for heating can be 100% utilized, and the heat efficiency is remarkably improved.

The range of the spout 4 where the spout faces the belt 2 is set lower than the height position of the top surface of the belt 2 and therefore the disturbance of the molten metal surface during casting is prevented. The quality of the ingot is thus improved.
