Title: Production of magnetic recording medium
Inventor: TAKAGI HIROTSUGU
IPC: G11B5/85
Filed: 1986-02-20
Abstract: PURPOSE:To improve corrosion resistance and wear resistance without decreasing output by forming a magnetic recording layer of a ferromagnetic metal essentially consisting of Co directly or via an intermediate layer on a nonmagnetic substrate then forming a Co oxide layer on the magnetic recording layer of the ferromagnetic metal and implanting oxygen ions to the Co oxide layer. CONSTITUTION:The magnetic recording layer of the ferromagnetic metal essentially consisting of Co is formed by a method such as vacuum deposition, sputtering, a plating, etc., directly or via the intermediate layer on the nonmagnetic substrate. Co is then subjected to vapor deposition or sputtering in an oxygen atmosphere to form a cobalt oxide layer and thereafter the oxygen ions are implanted to the Co oxide layer. Alloys such as Co-Ni, Co-Cr, Co-V, Co-Pt, Co-Ni-P, and Co-Re essentially consisting of Co are selected as the magnetic metallic material to form the magnetic recording layer of the ferromagnetic metal essentially consisting of Co. The thickness of the Co oxide layer is preferably 50-300Angstrom , more preferably 80-200Angstrom  in order to satisfy the corrosion resistance and wear resistance and the large reproduction output.

Title: Production of main magnetic pole of magnetic head
Inventor: KATOU NOBUAKI
IPC: G11B5/17
Filed: 1984-02-23
Abstract: PURPOSE:To improve the junction strength and to simplify the winding work by joining a nonmagnetic matter to a groove of a magnetic matter via the glass to obtain a pair of reinforcement members through junction with formation of a magnetic thin film and forming a winding groove after putting together those two reinforcement members. CONSTITUTION:A nonmagnetic matter 3 is joined to a junction groove 11 formed at the front face of a soft magnetic matter 7a such as ferrite, etc. via the glass 12a. Thus a pair of reinforcement members are obtained after applying the mirror surface finishing to the side face of each member. Then a magnetic thin film 2 is formed to the side face of each reinforcement member to put together both members. Then a winding groove 8 is formed and a coil is put into the groove 8. Thus a main magnetic pole is produced with junction of a soft magnetic matter 7b such as ferrite, etc. The junction strength is improved by the mutual diffusion of the matter 7a and the glass 12a and the existence of the groove 11. Furthermore a winding work is simplified since insertion of a coil is possible during production of the main magnetic pole.

Abstract: PURPOSE:To obtain a compound semiconductor device whose characteristic is good by a method wherein an annealing protective film is constituted of the following: an insulating film formed on a compound semiconductor substrate; and a high-melting point metal film formed on the insulating film. CONSTITUTION:A high-melting point metal film 8 is formed, on an insulating film 7, of a high-melting point metal whose coefficient of thermal expansion is smaller than that of the insulating film 7 and a compound semiconductor. A thermal stress of compression which is caused by the difference in a coefficient of thermal expansion between them is generated in a semiconductor substrate 1 during an annealing operation. Consequently, a thermal stress of tension which is caused by the difference in the coefficient of thermal expansion between the insulating film 7 and the compound semiconductor and which is generated in the compound semiconductor substrate 1 is reduced by the thermal stress of compression which is caused by the difference in the coefficient of thermal expansion between the compound semiconductor substrate 1 and the high-melting point metal film 8 and which is generated in the compound semiconductor. Thereby, it is possible to obtain a compound semiconductor device whose characteristic is good.

Filed: 1997-02-20
Abstract: PROBLEM TO BE SOLVED: To shorten the process time for manufacturing a high-voltage stator winding by employing a method for pressing a unit coil sequentially from the central part towards the opposite end parts thereof, thereby shortening the time from the heating process to the tightening process in the manufacture of the unit coil. SOLUTION: A unit coil 130 is pressed in the horizontal direction by means of a horizontal pressing unit P61, while being clamped by opposite horizontal side plates 23, and pressed in the vertical direction by means of a vertical pressing unit P62, while being clamped by opposite vertical side plates 21. When the pressing order is set from the central part of the unit coil 130 towards the end part thereof, bubbles in an insulation layer 16 are migrated sequentially from the central part towards the end parts thereof and partially discharged to the outside. Since the effect of the bubbles is largest at the part C and decreases gradually toward the end parts, bubbles existing in the central part 131 of the insulation layer 16 in the unit coil 130 can be discharged or migrated to the end part which is affected less.

IPC: H04Q9/00
Filed: 1988-02-18
Abstract: PURPOSE:To improve the transmission efficiency of data by constantly recognizing the number of slave stations by a main station and changing the transmission/reception cycle of the data of the number of the sets of connections. CONSTITUTION:When there is the slave station where a transmission sequence is not assigned, a polling is executed precedingly to a timing signal in the sequence of the address of the slave station to assign the transmission sequence succeeding to the transmission sequence already assigned to other slave station to the slave station having a response and the slave station to which the transmission sequence is assigned receives the timing signal and transmits the data to the main station according to the assigned transmission sequence. In such a way, the main station constantly recognizes the number of the connections of the slave stations and changes the transmission/reception cycle of the data according to the number of the sets of the connections, thereby, when the number of the sets of the connections is small, the time of the transmission/reception cycle is shortened and only when it is required for the slave station to which the data should be transmitted, the data is transmitted from the main station, so that the transmission efficiency of the data is improved.
