Title: Heat treatment of magneto-optic thin film
Inventor: UNO TAKEHIKO
IPC: H01F41/22
Filed: 1992-04-13
Abstract: PURPOSE:To contrive a significant reduction in the propagation loss of light by a method wherein a thin film to be treated is heated and a DC electric field is applied to the thin film to be treated in the direction parallel to the normal of the film surface of the thin film to be treated. CONSTITUTION:An exhaust pump 12 is actuated to put the interior of a vacuum container 11 in a vacuum state and a current is made to flow through a heater 10 for heating to heat a substrate 2 with a magneto-optic thin film 1 formed thereon. After the substrate reaches a prescribed temperature, a voltage is applied to electrodes 4 and 6 and an electric field is applied to the film 1. In this state, after the substrate is left to stand for a constant time, the heating is stopped in a state that the electric field is applied to the film 1. In the case where a film to be treated is heat-treated, a DC electric field is applied to the film to be treated in the direction parallel to the normal of the film surface of the film to be treated. Thereby, the high-performance magneto-optic thin film, which is not obtained by a conventional method, can be obtained and there is a large effect on a reduction in the film thickness of an optical circuit.

Filed: 1981-07-30
Abstract: PURPOSE:To obtain uniform and excellent seam welding effect by lapping painted steel plates and starting seam welding after inserting a conductive shunt bar to the starting end of welding and thereby destructing the paint film of the starting point of welding completely. CONSTITUTION:Painted steel plates 2, 3 are lapped, and a nearly U-shaped shunt bar 1 made of a conductive material such as Cu etc. is inserted from the starting end of welding to the direction of welding. At this time, the shunt bar 1 is made the starting point of welding and seam welding electrode wheels 4a, 4b are brought into contact. Then, applied welding current flows through the shunt bar 1, and the paint film just below it is destructed by heat generated at this time, and this part is welded completely. This initial heat generation destructs the paint film along the weld line successively, and consequently, succeeding seam welding is performed completely. After completion of welding, bent part of the shunt bar 1 is cut by fusion. As the lower side falls down automatically, the upper part can be removed easily.

CONSTITUTION:When an electrostatic latent image is formed, the movable mirror 23 is rotated as shown by an arrow B and then the optical axis of the laser light beam 20 shifts from (a) to (b) to draw a line, but if the movable mirror 23 has deviation in the center of rotation to cause the movable mirror 23 to slants in a direction A or generate an error in the flatness of mirrors 22, 23 and 24, the optical axis of the laser light beam 20 illuminating a photosensitive drum 6 shifts as shown by a virtual line 20a. The shifting light beam is reflected by a slanting surface 27 which decreases in interval toward the photosensitive drum 6 alternately and decreases in optical axis width greatly in this process. Further, the condenser lens 25 has a photodetection surface 26 and said slanting surface 27 and is sectioned almost in a triangular shape.
