Title: Method and device of removing floating dust in high temperature atmosphere
Inventor: ISHIDA TAKASHI
IPC: F23J1/00
Filed: 1988-08-05
Abstract: PURPOSE:To take out floating dust and exhaust gas after collection to the outside of a system or for reutilization thereof and to prevent the occurrence of a clogging accident due to the residue of floating dust by a method wherein in a swirling atmosphere having temperature at which a noncombustible substance can be dissolved, floatable molten slug in exhaust gas is collected and agglomerated to return it to the discharge side. CONSTITUTION:A raw material C to be heat-treated is mixed with heated air A for combustion to feed the mixture to a melting furnace 3. The mixture is brought into a high temperature state, an incombustible substance in the raw material C produces molten slug H, and a combustible substance is gasified to produce exhaust gas D. The slug H produces cooled slug E by means of a residue discharge device 5 and is discharged to the outside of a system. Meanwhile, most of a gas flow in the melting furnace 3 contains floating dust J formed by liquid drops of molten slug and is forcibly turned in the direction of a floating substance removing device 4 so that it is forced into a revolving flow state. A centrifugal force is exerted on the gas flow, which is caught by the inner wall surface of the device 4 and is moved to a bottom. The gas flow is heat-insulated by means of exhaust gas D moved in a counterflow state to the flow of the slug J, and is returned to the melting furnace 3 in a state keeping fluidability.

Title: Magnetic head for computer
Inventor: YAGI HIROSHI
IPC: G11B5/60
Filed: 1991-07-11
Abstract: PURPOSE:To improve characteristics by forming the slider 1 and/or magnetic head core of the MIG head of material having the lower magnetic permeability than the magnetic permeability of ordinary ferrite. CONSTITUTION:The magnetic permeability over the entire part of the magnetic head decreases and the input impedance can be decreased if the slider and/or the magnetic head core is formed of the material having the low magnetic permeability. Then, the resistance to a high-frequency writing current does not increase and the self-resonance point does not fall and, therefore, the driving of this magnetic head is easy. Namely, the characteristics approximately equal to or better than the characteristics of a thin-film head are obtd. by the constitution of the conventional MIG head.

Title: Thin film type thermal head
Inventor: TAKADA NORIMASA
IPC: B41J2/345
Filed: 1984-09-19
Abstract: PURPOSE:To make it possible to perform high speed good printing, by arranging a common electrode so as to overlap partial glaze. CONSTITUTION:When a common electrode 4 is arranged so as to overlap partial glaze 5, an electrode with a wide area is overlapped to the partial glaze. The electrode has good heat conductivity and the heat resistances of a route escaping the heat remaining in a heat generating resistor part and partial glaze to a substrate 5 through an electrode 3 and the common electrode 4, and the route escaping the same to the surface of a head through the electrode 3 and the common electrode 4 are markedly reduced and the heat during the time, until the printing pulse in the next printing cycle is started after one printing pulse was finished, is sufficiently dissipated. Therefore, it is eliminated that the heat remaining, when high speed printing was performed, is accumulated and the temp. of the heat generating resistor part rises abnormally to bring about destruction and a thermal head imparting good printing quality at a high speed and having high reliability is obtained.

Abstract: PURPOSE:To reduce noises on the operation of a mixer by applying first and second superconductive electrodes on both sides of a first insulator or a semiconductor while holding the insulator for the semiconductor and forming a quasi-particle injection electrode consisting of a superconductor to the surface of either of these electrodes through a second insulator. CONSTITUTION:A first superconductive electrode 2 and second superconducting electrode 3 are applied on both sides of a first insulator 1 while holding the insulator 1, and a quasi-particle injection electrode 5 composed of a superconductor is shaped to the surface on the outside of the electrode 3 through a second insulator 4, thus forming a superconducting mixer element. According to such constitution, the electrodes 2 and 3 are operated at a sufficiently low temperature so as to be brought to a superconductive state and the same mixer operation as conventional devices is conducted, but AC Josephson currents are reduced by excess quasi-particles when the electrode 5 is biassed and quasi-particles are injected into the electrode 3. Consequently, one of the elements of mixer noises is eliminated. The superconductor is used as the electrode 5 at that time, but a normal conductor may be employed.
