Title: Magnetic recording medium
Inventor: TAKAO MASATOSHI
IPC: G11B5/66
Filed: 1978-04-27
Abstract: PURPOSE: To improve the corrosion- and wear- resisting properties of a magnetic recording meiudm and to prevent the magnetic characteristics from being deteriorated by forming a thin film of metal nitride on a thin film of a ferromagnetic material formed on a non-magnetic substrate.  
     CONSTITUTION: There is formed on a non-magnetic substrate 1 such as a high molecular film a magnetic thin film 2 which is made mainly of metal, its alloy or an inter-metal compound. There is further formed thereon a thin film 3 of metal nitride by the known vacuum evaporation, sputtering and ion plating methods in the vapor of nitrogen compounds such as N 2  or NH 3  which can produce a nitride film at a relatively low temperature such that it has a uniform thickness in parallel with the roughness of the substrate 1. Thus, it is possible to held the substrate 1 and the thin film 2 at a temperature lower than 100°C when the thin film 3 is to be formed.

Title: Absence transfer system
Inventor: NAKAI TATSUO
IPC: H04M3/54
Filed: 1979-04-26
Abstract: PURPOSE:To prevent transfer release of the extension, where absence transfer is registered, from being forgotton, by making absence transfer registering to a call, which occurs from the transfer destination extension to the transfer source extension, ineffective. CONSTITUTION:When the number of transfer source extension A is dialed from transfer destination extension B, originating register OR starts marker M to transfer the dial number of called extension A and storage position information of calling extension B to marker M. Marker M transmits the number of extension A to number group NG to obtain called information of extension A and discriminates on a basis of storage position information that extension A is in the absence transfer class, and marker M starts converting circuit TC corresponding to extension A to obtain position information of transfer destination extension B. Marker M collates storage position information of calling extension B and storage position information of transfer destination extension B with each other by collating circuit ID. When agreement is detected by circuit ID, absence transfer registering is made ineffective temporarily, and incoming connection of extension A is performed from extension B, and absence transfer registering release is proposed to extension A from extension B.

Title: Fan apparatus for air conditioner
Inventor: HAMAIDE NOBUMASA
IPC: F04D29/54
Filed: 1990-03-05
Abstract: PURPOSE:To put a protective net without increasing height as a whole and to prevent the vortex flow of air flowing from a heat exchanger to a fan by providing the fan at the internal position of the air blowoff port provided to the upper surface of a shroud and bending the inner end part of the cylindrical part of the shroud into a circular shape in the upward direction of the inner periphery or the shroud. CONSTITUTION:The lower end part of the cylindrical part 12 of a shroud 9 is formed into a protruding part having a circular arc shape in a downward direction. Therefore, the air passing through a heat exchanger 2 becomes easy to flow toward a fan 7 and, since the vortex flow of the air is prevented, the flow resistance of the air between the heat exchanger 2 and the fan 7 can be reduced. Since the fan 7 is positioned inside the upper surface of the shroud 9, the shape of an air conditioner can be prevented from increasing in its height direction and, therefore, a planar protective net can be directly arranged to the upper surface of the shroud 9 and the constitution of the fan apparatus becomes simple and the manufacturing cost thereof can be reduced.

IPC: C22C9/06
Filed: 1984-03-17
Abstract: PURPOSE:To provide a titled clad material which has high joining power, does not peel during expanding and is suitable as a corrosion-resistant material by joining a copper alloy material having the specific compsn. consisting of Be, Ni, Al and Cu to an iron or steel base material and expanding the same. CONSTITUTION:A copper alloy material consisting of 0.01-2.0wt% Be, 5.0- 30.0% Ni, 0.1-8.0% Al and the balance Cu is joined to an iorn or steel base metal by explosive welding, hot press welding, cold press welding, etc. and is further expanded by rolling, by which a thin clad material is obtd. without peeling of each material. If the component compsn. of the above-mentioned copper alloy material deviates from the above-mentioned compsn. range, the joining performance is decreased and the materials are peeled during expanding so that the formation of the clad material is not feasible. The hardness of the clad material is improved further by annealing the material at about 300-400 deg.C. The clad material exhibits the higher corrosion resistance to sea water, ammonia atmosphere, etc.

Title: Manufacture of iron core for electromagnetic induction machinery and apparatus
Inventor: OKAMURA TAMOTSU
IPC: H01F41/02
Filed: 1987-03-09
Abstract: PURPOSE:To perform the fixing process of an iron core while suppressing the internal strain of the iron core to a small value by annealing an iron core made of an amorphous magnetic material, and applying a paint or bonding agent to the edge face of the iron core when the temperature decreases and hardening it. CONSTITUTION:An iron core 1 is formed of an amorphous magnetic material, and it is annealed at 400 deg.C by heating furnaces 11, 12 to remove the mechanical strain. Then, when the temperature of the iron core 1 is slowly cooled to 200+ or -50 deg.C in a slow cooling chamber 15, a bonding agent is applied to the edge face of the iron core 1 with spray nozzles 18 and hardened by heat inertia. Therefore, the edge face of the iron core 1 is covered with a hardened coating film 2 of the bonding agent, whereby the fragility of the amorphous magnetic material is improved. Also, since the coating and hardening are performed in the process of slowly cooling the iron core, even if a bonding agent of the organic system is utilized, it does not penetrate into the core. With this, the fixing process of an iron core made of an amorphous magnetic material can be performed while suppressing the internal strain of the iron core to a small value.
