Title: Measuring method for track width of thin film mr magnetic head
Inventor: SHIMIZU TAKAHIRO
IPC: G01B11/02
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To accurately measure the track width at a low cost by utilizing a characteristic that a boundary section between a metallic section and a ceramic section corresponding to a track width is projected. SOLUTION: In a processing process of an MR head, layers of metallic sections and ceramic sections are formed in an order of sections 11, 12, 13, 14 and 15. A measuring object is an interval between a section (a) where a thickness of a thin film of the metallic section 13 is small and a section (b). The layers of ceramic section 14 and metallic section 15 are formed thereon so that sections 14, 15 have irregularity by being influenced by the thin film of the section 13. As a result, a projection section of a boundary between the ceramic section 14 and metallic section 1 5 is utilized.  A scanning line position of a two-dimensional sensor where dimension of the width obtained from a contrast waveform in a direction perpendicular to a width direction of a track of the magnetic head becomes a prescribed relative level with respect to a width of a gap section is detected, then the number of lines between detected positions so that measurement of the track width is performed.

Title: Detection of end point of welding
Inventor: MURAKAMI YASUO
IPC: B23K9/127
Filed: 1983-03-31
Abstract: PURPOSE:To emit an instruction for stopping welding or an instruction for correction in arc welding by detecting the end point of welding of two works or arrival at the corner work by the signal of the welding current value deviating downward or upward from a blind sector value near the end point of welding. CONSTITUTION:A torch T welds works W1, W2 with the current from a welding machine M. The current of a detecting part 1 enters comparing parts 3U, 3D for upper and lower deviations through a low pass filter 2. The upper limit and lower limit of the blind sector are set respectively in the parts 3U, 3D, and the excess signal is transmitted to a deviation discriminating part 5. The part 5 detects the end point of welding or the arrival point at the corner work by making overall discrimination with the signal approaching the terminal from the machine M and the signal from a torch position detector 4 and a stop or correction instruction is emitted from an instructing part 6 to the machine M. The end point of welding is thus detected easily without making intricate operation.

The concn. of the alkali soln. is preferably about 5-30%, the treating temp. 10-60 deg.C, and the amount of the soln. applied about 1-50mg/cm<2>. The surface treated Al is then plasma-oxidized with a plasma incinerator to form an oxide coat with superior corrosion and wear resistances on the Al surface. Org. matter on the Al surface is forced to be burned by the plasma oxidation, so no org. matter hinders the formation of the oxide coat, and the pretreatment and the control of the treating soln. are facilitated. By regulating the kind, amount and concn. of the alkali treating soln., the thickness of the oxide coat can be regulated simply.

Filed: 1989-03-10
Abstract: PURPOSE:To eliminate the blurring of colors and to lower the resistance of transparent electrodes by subjecting the boundary parts of picture elements to light shielding by non-light transmittable conductive films and connecting the non-light transmittable conductive films to the adjacent transparent electrodes. CONSTITUTION:An insulating layer 6C is formed between two pieces of the adjacent transpar ent electrodes 4B and the non-light transmittable conductive film 7C is disposed on the insulat ing layer 6C along the transparent electrodes 4B and is insulated from the other non-light transmittable conductive films. Further, the respective non-light transmittable conductive films 7C have extension parts 7C' on the boundaries between the picture elements and picture elements arrayed on the same color filters. The extension parts 7C' are connected to the transparent electrodes 4B to electrically connect the transparent electrodes 4B and the non-light transmittable conductive films 7C. The non-light transmittable conductive films 7C are formed like Venetian blinds in such a manner and the extension parts 7C' thereof form the non-light transmittable conductive films. Since the boundary parts of the picture elements are shielded of light by these films and the non-light transmittable insulating layers 6C, the blurring of the colors between the picture elements is obviated. Since the respective transparent electrodes 4B and the non-light transmittable conductive films 7C are connected in parallel, the resistance of the transparent electrodes 4B is substantially lowered.
