Patent JP-H01260612-A (JP)
Title: Manufacture of magnetic head
Inventor: SAOSHITA SOUSHI
IPC: G11B5/23
Filed: 1988-04-08
Abstract: PURPOSE:To ensure excellent characteristics as a floating-type magnetic head by subjecting a ferrite substrate to heat treatment prior to forming a film of Fe-Al-Si alloy on a part constituting a gap. CONSTITUTION:Prior to forming an alloy film of Fe-Al-Si on a part constituting the gap, the substrate is subjected to heat treatment. Therefore, in the ferrite substrate, a layer containing a large amount of oxygen in such layers modified by the process can be removed by heat treatment, which reduces an influence of oxygen on aluminum in the Fe-Al-Si alloy film during deposited on the ferrite substrate by sputtering. By this method, the excellent characteristics of Fe-Al-Si film can be thereby sufficiently made use of for the floating magnetic head.

Title: Paper guide and attachment
IPC: G03D3/08
Filed: 1992-03-10
Abstract: PURPOSE:To prevent the damage of a photographic printing paper and its pollution caused by the damage by expanding the part in vicinity of the top end of a paper guide above the liquid surface of the developing liquid of the paper guide, toward the outside from a guiding surface. CONSTITUTION:The paper guide 3 is made of hard synthetic resin, and constituted so as to integrally form an expanded part 5 with a main body 4, in the direction (in front) of a sliding surface 6 above the main body 4. The expanded part 5 is gradually expanded out from the vicinity where it is positioned above the liquid surface 2 of the developing liquid. Then, the photographic printing paper transferred by rollers A and B is abutted on the expanded part 5, and then, pushed downward by the rollers. At this time, solid matter is stuck to the paper guide 3 as well. Since the expanded part 5 is formed above the liquid surface 2 of the developing liquid, the solid matter is stuck on the part below the expanded part 5, and never stuck to the expanded part 5. Therefore, the contact of the photographic printing paper with the solid matter can be prevented.

Title: Method for detecting flaw on surface of metallic object
Inventor: KITAGAWA TAKESHI
IPC: B22D11/16
Filed: 1982-05-24
Abstract: PURPOSE:To increase the S/N ratio of a defect signal and to make the remedy for heat resistance of a light projector and a photodetector easy, by setting the angle between the incident direction of the irradiated light from the lateral side of a traveling line for a specimen and the normal of the surface of the specimen at 15-55 deg.. CONSTITUTION:A laser light source 22 disposed in the diagonal direction intersecting orthogonally with the traveling direction of a continuous casting slab 20 on the lateral side of the traveling line of said slab irradiates external light in such a way that the angle theta1 between the normal on the surface of the slab 20 and the incident direction of the irradiated light attains 15-55 deg.. The laser light 22a is expanded to a belt shape up to the necessary visual field on the slab 20 by a cylindrical lens 24. On the other hand, a photodetection camera 26 disposed in the position on the lateral side opposite from the slab traveling line where the angle between the normal on the surface of the slab 20 and the photodetection direction of the reflected light is equal to theta1 detects the specular reflected light, and a signal processing circuit 28 outputs a defect signal. The S/N ratio of the detect signal is thus made >=2.0 and the distance between the camera 26 and the slab 20 is taken large, whereby the remedy for heat resistance is made easy.

Abstract: PURPOSE:To perform mutually a backup by means of one set of monitor controller, by switching a selection signal for calling the monitor controller of a controller to be monitored by means of a controlling signal from the monitor controller. CONSTITUTION:If a monitor controller 1 in the 1st group becomes impossible to use, a monitor controller 4 in the 2nd group sends a controlling signal, which switches the monitor controller from 1 to 4, to a controller 3 to be monitored in the 1st group. The monitor controller 3 switches a selecting signal from 1 to 4. Therefore, a monitor signal is transmitted to the monitor controller 4 in the 2nd group through a public communication circuit or subscriber's telephone circuit so that the backup is performed. For releasing, the monitor controller 1 in the 1st group transmits a controlling signal, which returns the monitor controller from 4 to 1, to the controller 3 to be monitored. The controller 3 returns the selecting signal from 4 to 1. As the result, the monitor signal is transmitted to the monitor controller 1. In the same manner, the monitor controller 1 in the 1st group can monitor and control the controller 5 to be monitored in the 2nd group.

Filed: 1996-04-11
Abstract: PROBLEM TO BE SOLVED: To alleviate a stress developed in a step for relieving an electric field and prevent developing a crack it the like in an insulating material by forming a predetermined angle between an insulating spacer at the step for relieving the electric field formed in a metal insert and a center axis. SOLUTION: A step 4 for relieving an electric field is formed ion a metal insert 2.
