Title: Magnetoresistance effect type head
Inventor: NOMURA AKIHIKO
IPC: G11B5/39
Filed: 1994-09-29
Abstract: PURPOSE: To suppress Barkhausen noise by laminating antiferromagnetic films to control the magnetic domain structure at specified positions in a magnetoresistance effect film and a soft magnetic film. CONSTITUTION: An MR element 30 is disposed between magnetic shield films 5a, 5b with an insulating film (not shown) interposed. In this element 30, a soft magnetic film 3, antiferromagnetic film 7 to control the magnetic domain structure of the soft magnetic film 3, nonmagnetic intermediate film 2, MR film 1, antiferromagnetic film 6 to control the magnetic domain of the MR film 1, and electrodes 4 are laminated in this order. The track width of the MR head 30 is about several μm. The MR film 1 consists of a ferromagnetic material such as 'Permalloy (R)' and is about 20-50nm thick. The antiferromagnetic film 6 consists of, for example, a FeMn alloy and is about 20nm thick. The MR film 1 and the antiferromagnetic film 6 are formed after the nonmagnetic intermediate film 2 is formed.  In this process, these films are formed while an external magnetic field is applied along the longitudinal direction of the MR film. By this method, the axis of easy magnetization of the soft magnetic film 3 and the axis of easy magnetization of the MR film are made to cross perpendicular to each other, and further, the magnetic domains in each film can be controlled to suppress Barkhausen noise.

Title: Transparent conductive film and its manufacture
Inventor: MURAHARA MASATAKA
IPC: C23C16/40
Filed: 1991-10-07
Abstract: PURPOSE:To manufacture a transparent electrode having low resistivity at a low cost by radiating a laser light to a mixed gas made from a compound of Al and Sn in a specific divided pressure ratio and educing a transparent conductive film in which Al is doped into SnO2. CONSTITUTION:A mixed gas made from Al(CH3)3, Sn(CH3)4 and N2O as a row material for a transparent conductive film is enclosed in the reaction case 10 and the divided pressure of a compound of Al and Sn is adjusted to 0.1 to 0.7. A KrF eximer laser light L1 is radiated to the row material when a substrate 18 is at 250 degree centigrade. A SnO2 film 19 in a conduction of a circuit pattern in which Al is doped is educed on the substrate 18. The light transmittivity of the educed film 19 is 80% when the divided pressure ratio of Sn(CH3)4 to N2O is 1:5 and 100% when the divided pressure ratio is 1:20. The resistivity of the film turns to the minimum value when the divided pressure ratio of Al(CH3)3 to Sn(CH3)4 is 0.45. Thus, a transparent electrode having a low resistivity is manufactured at a low cost by mixing a very little amount of Al into SnO2.

Title: Fluorine inclusive elastomer covered wire/cable
Inventor: NAKABASHI MASANOBU
IPC: H01B3/44
Filed: 1988-10-14
Abstract: PURPOSE:To improve carvature resistant fatigue characteristic by forming a covered layer out of a composition including a specified copolymer, and by crosslinking the covered layer. CONSTITUTION:A covered layer is composed of a tetrafluoroethylene-propylene- vinylidene fluoride copolymer of 40,000 to 60,000 number average molecular weight and a tetrafluoroethylene-propylene-vinylidene fluoride copolymer of 80,000 to 100,000 number average molecular weight. A weight ratio for both of these is 95/5-50/5, and a crosslinked covered layer is used.

Title: Board structure of thermal head
Inventor: EBIHARA TAKASHI
IPC: B41J2/335
Filed: 1988-10-14
Abstract: PURPOSE:To obtain a board structure of a thermal head in which the thickness of a glazed layer is abruptly made uniform by chamfering both edges between a main face and an oblique face, and between the end face and the oblique face. CONSTITUTION:An oblique face 6 is formed between the main face 4 of a base member 2 and an end face 5 of a board 1, and edges between the face 4 and the face 6, and between the face 5 and the face 6 are chamfered by cutting with ruby grindstone, etc. Chamfered parts 6a, 6b having a width (s) of half or less of the width t' are formed, and the edges are not sharpened as conventional ones by the chamfering. Accordingly, a glass glazed layer 3 is not thinned. Thus, the irregularity in the thickness of the layer 3 is reduced merely by chamfering the edges between the face 4 and the face 6, and between the face 5 and the face 6. For example, since a discontinuous part is not formed at the glazed layer, the yield of manufacturing the board is improved to reduce its cost.

Filed: 1987-10-14
Abstract: PURPOSE:To improve the surge resistance of an output terminal having an LDD(lightly doped diffusion) structure by providing the output terminal with a field transistor serving to absorb surge. CONSTITUTION:A surge voltage tends to undergo punch-through from n<+>-layers 32, 34 through n<->-layers 37, 38 when applied to an output terminal 11. However, since it is constructed so that a punch-through from the n<+>-layers 32, 34 through fields 41, 42 toward the GND of an N-layer 33 precedes thereto, heat generation by currents flowing in the n<->-layers 37, 38 being suppressed, whereby its surge resistance is improved. The LDD structure serves to suppress the punch-through of the transistor, and the prioritization of punch-through can be implemented by detailedly forming field separating parts 41, 42. Accordingly, currents generated by the surge voltage applied to the output terminal flow in the field transistor 53 for absorbing the surge, whereby the surge resistance of the semiconductor device is increased.
