Title: Laminated magnetic thin film and magnetic head using the same
Inventor: NAKATANI RYOICHI
IPC: H01F10/08
Filed: 1988-03-25
Abstract: PURPOSE:To obtain low coercive force, high magnetic permeability and high saturation magnetic flux density, by making the crystal structure of one laminated thin film face-centered cubic lattice, and specifying the lattice constants. CONSTITUTION:An Fe thin film, and an alloy thin film 11 whose main component is Fe are stacked via a thin film 12 of other composition, and a lamination structure is constituted. The crystal structure of the thin film 12 is made face- centered cubic lattice or a structure similar thereto, and the lattice constants are set in one range out of the following; 3.243-3.296Angstrom , 3.322-3.375Angstrom , 3.744-3.805Angstrom , 3.835-3.897Angstrom , 3.973-4.038Angstrom  and 4.070-4.135Angstrom . Thereby, characteristics of low coercive force and high magnetic permeability can be obtained. The saturation magnetic flux density is decreased by the effect of lamination, however, as compared with the case where SiO2, Al2O3, etc., are interposed, the saturation magnetic density is enhanced.

Title: Method and device for welding plate materials
Inventor: NIIMI AKIHIKO
IPC: B23K26/21
Filed: 1984-04-06
Abstract: PURPOSE:To improve welding quality by setting a pair of laser beams having respectively different optical axes in such a way that the focuses at the butt parts of plate materials are parted at a prescribed interval and irradiating alternately the laser beams at every prescribed time. CONSTITUTION:The pulse laser beams 9, 9' passing through condenser lenses 3, 3' via reflecting mirrors 4, 4' and 5 are condensed to the converging beams which melt the plate materials 1, 1' at the respective arrival points 10, 10' when the beams 9, 9' are alternately irradiated to said materials at every prescribed time. A part 8 to be welded is therefore alternately welded when the materials 1, 1' are so moved that the part 8 faces the top end of a working head 7 and when an assist gas is supplied from a gas supply port 6. The quality of the weld zone is assured even if the space in the joint part is increased and therefore the welding quality is improved by the above-mentioned method.

Filed: 1988-03-25
Abstract: PURPOSE:To simplify a carriage structure and to also reduce the size thereof, by constituting the same so that the rotary shaft of a motor is pierced through a plurality of pulleys and the films of a plurality of head units are run by one motor. CONSTITUTION:All of pulleys 22a-22d for allowing films 23a-23d to run are connected to the rotary shaft 27 of the motor 26 mounted on a carriage 20d and the films 23a-23d are simultaneously allowed to run by one motor 26. However, when four color inks are used in order to perform color recording, four head units equipped with thermal heads, films and ink supply mechanisms are required and it is necessary to mount four motors being driving sources for running the films heretofore. Since four films 23a-23d can be allowed to run by one motor 26 in this case, the whole of the carriages 20a-20d having the films and the pulleys mounted thereon is reduced and a structure can be also simplified.

Title: Refrrigerator
Inventor: MITANI AKIO
IPC: F25D21/04
Filed: 1978-06-12
Abstract: PURPOSE: To enable defrosting to be achieved without warming wall of a refrigerating chamber by providing another low-temperature cooling unit, separately from a cooling unit attached to the refrigerating chamber, in such a manner as to become tightly in contact with the refrigerating chamber so that frost in the refrigerating chamber can be transferred to the lowe-temperature cooling unit and removed by being warmed.  
     CONSTITUTION: When inside temperature of a cooling unit 2a of a refrigerator in operation at refrigeration cycle became below 0°C, the interior wall starts becoming frosted. As No. 3 evaporator 12 is made for lower temperature than No. 2 evaporator 10, the frost adhering to the No. 2 evaporator is gradually sublimated and evaporated, and the steam moves concentrically toward the No. 3 evaporator and adheres to it. After the frost adhered to the surface of the No. 3 evaporator 12 became a prescribed thickness, an electric heater is turned on to melt the frost, and the water flows into an evaporation plate 4 to be evaporated. As the evaporator 12 is kept away from the interior wall of the refrigerating chamber 2a, defrosting process is able to be achieved without warming the refrigerating chamber.

Abstract: PURPOSE:To omit conversion of length on a map into distance and time required for conversion and to remove errors due to the conversion by displaying an optional point on the map by two-dimensional coordinates and inputting a departure position and an objective position at least as coordinate formats. CONSTITUTION:A process memory 15 is constituted by an RAM and the coordinates of a crossing to be an object and the turning directions in addition to the coordinates of a departure position and an objective position are successively stored. Data can be inputted to the process memory through a keyboard 3 or a magnetic card reader 2. If only the departure position coordinates and the objective position coordinates are inputted, the coordinates of crossings close to a line connecting two coordinates are successively retrieved from a crossing memory 14 and can be automatically set up in the process memory 15. Since it is unnecessary to convert the length on the map into a distance, errors due to conversion or the time required for conversion can be removed and the input operation of an optional point on the map can be performed rapidly and precisely.

Abstract: PURPOSE:To improve the reception rate of a mobile station by allowing a base station to send a polling request signal having a transmission frame number for a prescribed number of times and allowing the mobile station to send a reply data signal according to the preset order after the end of transmission. CONSTITUTION:The base station 11 sends a polling request signal having a transmission frame number for a prescribed number of times. The mobile station 16 calculates the transmission end time of the polling request signal from the transmission frame number at the reception of the polling request signal and sends the reply data signal according to the preset order after the end of transmission. Thus, even when the reception period of each mobile station 16 in the same group differs from plural number of times of polling requests, each mobile station 16 decides the reply period of its own statiion baaed on the polling end time and the slot number. Thus, the reply data signals from each mobile station 16 are sent synchronizingly in the order of slot number without being overlapped together.
