Filed: 1984-05-25
Abstract: PURPOSE:To heat-treat nearly simultaneously, by irradiating a fine electron beam simultaneously or in time-series with a fine ion beam, in a state overlapping the ion beam, while irradiating the fine ion beam of an impurity element in semiconductor to ion-implant locally. CONSTITUTION:By applying positive and negative alternate voltages to the charged particle source 1, electron and ion beams 17 are extracted, which are then focused on a material by lenses 3, 5. Both the positions on the material irradiated by the electron and ion beams are being displaced by a given interval by magnetic field resulting from deflection electrodes 8, while both the charged particle beams 17 are scanned by a given distance at a given place on the material by electrostatic deflection electrodes 7. In this case, it can be changed by changing the direction of the deflecting magnetic field whether the electron beam or the ion beam precedes in the scanning direction. The beam displacing amount is determined using a displacing amount of images which are pictured as scanning images of both the charged particle beams on a CRT15. Moreover, pattern scanning of the ion beam may be done using CPU control system 16.

IPC: G11B33/02
Filed: 1994-05-19
Abstract: PURPOSE:To relax a restriction of disposition of the device by loading a disk in moving parallel to a mounting surface of a tray. CONSTITUTION:At the time of fitting an optical disk D 9 to a D mounting part 2, a projecting part 5a is protruded to the side of the center of the mounting part 2, and even when a disk drive device is disposed sidewise to make the surface of the tray 1 vertical, the D 9 is not detached from an upper surface of the mounting part 2. When the device is disposed sidewise, the D 9 is dropped in the mounting part by gravity, but is supported by a guide wall 3, and unbalance of positioning the D 9 in the mounting part 2 due to the droppage is small. Consequently, a discrepacy between the center of the D 9 and the center of the mounting part 2 is small, and also the D 9 is prevented from tumbling in the inserting direction by a circular-arcuate part of a D guide wall 4a in front of the center of the mounting part 2. When the D 9 is delivered to a turntable, the D 9 is clamped by a clamp mechanism. A pickup, etc., enters an opening part 10 to write and read information. Thus, the D 9 is stably fitted to the mounting part 2, and hence the device can be used even sidewise, and also the restrictions of its disposing place, etc., can be relaxed.

Abstract: PROBLEM TO BE SOLVED: To reduce rocking of a marine vessel utilizing energy of waves which is an abstruction for sailing of the marine vessel in the prior art, to assist propulsion of the vessel to increase its speed, and to save fuel. SOLUTION: A wing 1 is provided under water to be oscillated around an axis 2 in the vicinity of its front end, and an elevation relating to an advancing direction of a marine vessel is made to be zero normally by force of a spring 4. Since a direction of the wing 1 provided under water is held all the time in an intermediate position between the advancing direction of the vessel and a direction of a relative water flow facing to the wing 1 by balance between force of the relative water flow facing to the wing 1 and the force of the spring 4, advancing force is generated when a component in the advancing direction of the vessel of lift generated in the wing 1 by the water flow is larger than that in the reverse direction of the advancing direction of drag generated in the wing 1. Rolling is reduced at the same time because energy of waves is taken away by the action mentioned above.
