Title: Thin-film magnetic transducer
Inventor: UIRIAMU CHIYAARUZU KEIN
IPC: G11B5/31
Filed: 1993-11-04
Abstract: PURPOSE: To obtain a thin film magnetic head. CONSTITUTION: This thin film magnetic head contains some groups of gap layers 31-33 each made of nitrided and hydrogenated amorphous carbon. This head contains a thin film writing layer 26 and two thin film reading layers 28 (separately positioned on the MR layer sides) and each of the layers 26, 28 is made of amorphous carbon doped with <=25at.% nitrogen and 5-25at.% hydrogen. The nitrogen existing in the amorphous carbon remarkably relieves the stresses of the layers. Since the layer 26 does not peel from its adjacent layer 30 made of other material such as ferrite or an Ni-Fe material even in the case of >=2,500Å thickness, it is not necessary to interpose a middle layer between the layers 26, 30. Since the hydrogen in the layer 26 extremely increases hardness, the wear of this head is suppressed.

Title: Semiconductor pressure sensor
Inventor: TAKEUCHI TAKANOBU
IPC: G01L9/04
Filed: 1989-10-23
Abstract: PURPOSE:To detect with high sensitivity a force acting on a diaphragm by a method wherein a resistance value for a unit length of a second part intersecting a crystal axis perpendicularly is made smaller than the one of a first part along the crystal axis. CONSTITUTION:A P-type region is provided by ion implantation in the vicinity of the peripheral edge of a diaphragm 3 in the central part of an N-type semiconductor chip 1, so as to form a pressure-sensitive resistance 2, and a change in resistance value caused by a piezo resistance effect is utilized. In a pressure- sensitive resistance element thus formed, the resistance value for a unit length differs between a first part along the crystal axis and a second part intersecting the axis perpendicularly, and the resistance value of the later part is smaller than that of the former. On the occasion, a rate at which a change in the resistance of the first part offsets a change in the resistance occurring in the second part is lessened by a pressure acting on the diaphragm, and a large change in the resistance value occurs in the whole of a pressure-sensitive resistance. Accordingly, a high detection sensitivity is obtained.

Title: Standard particle
Inventor: MIURA MASAO
IPC: G01N1/00
Filed: 1990-10-15
Abstract: PURPOSE:To obtain the relationship of 1:1 between the diameter of a standard particle and a scattering cross-sectional area for light having any wavelength and to make it possible to use the particle as a calibration standard by using the material which has no light transmitting property at all and does not absorb the light as the material for the standard particle. CONSTITUTION:The material of a standard particle, e.g. a metal, has no light transmitting property at all and does not absorb the light. Therefore, the material is only the component which reflects the light from the surface of the standard particle. The scattering of the light is not deteriorated regardless of the diameter of the standard particle even in the light having any wavelength. Therefore, linearily is observed in the relationship between the diameter of the standard particle and the scattering cross-sectional area. The correspondence of the 1:1 relationship can be provided between the diameter of the standard particle and the scattering cross-sectional area. Therefore, when the scattering cross-sectional area can be measured for any wavelength, the diameter of the standard particle causing the scattering is determined as one value. Thus, the standard particle can be used as the calibration reference for a foreign-matter inspecting device.

Title: Overhead and flat position welding method
Inventor: MANABE YUKIO
IPC: B23K26/21
Filed: 1996-09-26
Abstract: PROBLEM TO BE SOLVED: To prevent the sag of molten metal, and to improve bead shape by generating Lorentz's force in the direction of a groove bottom in a molten pool by the action of current and magnetic field. SOLUTION: The current A in one direction is formed along the welding direction in the molten pool when the current is allowed to blow between wires 5a, 5b. The Lorentz's force 11 is applied in the direction of a groove bottom 21A by applying the magnetic field 9 in the direction parallel to the surface of a base metal and orthogonal to the uni-directional current A. In the overhead welding, the weld bead free from undercut on the upper side of the groove and defective meeting angle with the groove wall on the lower side of the groove can be obtained in the initial pass. In the second and subsequent welding, the weld bead free from defective meeting angle with the groove side wall on the lower side of the groove can be obtained similar to that in the initial pass.  In the flat position welding, the sagging of the molten metal to the base metal surface side is suppressed to realize the excellently efficient execution. The back bead shape is also excellent.

Abstract: PURPOSE:To prevent defective conveyance of image receiving sheet by forming a non-image forming area between image forming areas of an ink sheet and making the length of the non-image forming area in the conveying direction of the ink sheet longer than the length of an arc of a contact area at the time that the ink sheet is contacted to a platen roller. CONSTITUTION:In a state that an image receiving sheet 18 is not inserted between an ink sheet 8 and a platen roller 11, that is, the ink sheet 8 contacts to the platen roller 11 directly, a non-image forming area 17 of the ink sheet 8 is being contacted to the surface of the platen roller 11. As for the contact area, a length L of the non-image forming area 17 is longer than a length thetar of an arc at a contact area of the platen roller 11, so that image forming areas 8a at C and Y never contact to the platen roller 11 directly at a step that the image receiving sheet 18 is not inserted.
