Abstract: PROBLEM TO BE SOLVED: To provide a video image display method where a plurality of users can view a real time video image of an object at a remote place from a preferred direction and position in a three dimensional cooperative virtual space at the same time and the users can easily understand at which position and in which direction the video image is photographed. SOLUTION: Each of a plurality of users at remote places builds up a three dimensional cooperative virtual space in which an alter ego 13 expressed in a computer graphics can be operated on each computer terminal interconnected by a network and shares the space in common. A virtual camera 12 simulating a video camera is displayed in the three dimensional cooperative virtual space at a similar position to a relative position between a video camera in a real space and a photographing object in real time and a color of its locus 15A is changed as time elapses. A video image photographed from a relative position corresponding to an overlapped position between the user's alter ego 13 and the locus 15A of the video camera is displayed on the computer terminal of the user.

Filed: 1992-02-19
Abstract: PURPOSE:To prevent the contents of an image memory from being destroyed at the time of switching a clock or a synchronous signal by controlling an image memory reading stop function at the time of switching a scanning synchronizing mode. CONSTITUTION:A scanning synchronizing mode switching control circuit 1 outputs a read stop signal 16. When the signal 16 is invalid, an image reading circuit 12 successively forms read control signals 13 in accordance with clocks 6 while using synchronous signals 11 as triggers.

Title: Superconductive coil
Inventor: AZUMA TAKESHI
IPC: H01F6/06
Filed: 1979-03-23
Abstract: PURPOSE:To protect a superconductive wire from damage, deformation and snapping and prevent the deterioration in its properties, by tightly fitting the superconductive wire in the coiling recesses provided on winding frames and by overlapping the winding frames on one another. CONSTITUTION:A hollow superconductive wire is tightly fitted in the coiling recesses 13 of a plate-shaped winding frame 12. Such fitted superconductive wires are located adjacently to one another in an axial direction so that a superconductive coil 15 is formed. Since the coiling recesses 13 are provided on both the sides of each winding frame 12, the superconductive wires 10 are overlapped on one another between the adjacent winding frames in the axial direction of the coil. As a result, the radial component of an electromagnetic force caused by the wires is all directly corried by the winding frames but a portion of the axial component is not directly carried by the winding frames but carried by the adjacent wires. For this reason, the winding frames except for the central one are provided with the recesses 13 on only their sides facing the outside in the axial direction. According to this constitution, the wires 10 in the recesses 13 are all directly supported by the winding frames both in the radial direction nd in the axial direction.

Abstract: PURPOSE:To prevent a lead frame and a molded portion of a semiconductor from being deformed by forming a recess on the top of a conveying passage of conveying rails, supporting the molded portion of a work on the lower surface of the recess to support the impact force applied to the work by the injection of superhigh pressure water by the rail surface. CONSTITUTION:A pair of conveying rails 8 are so formed in the slide passage of a work that the interval of the opposed surfaces of a recess 18A is slightly larger than the thickness of the molded portion of the work and the interval of the lower side is smaller than the thickness of the molded portion of the work and thicker than the lead of the work at the recess 18A. Windows 14, 15 are so formed on the work 4 to be conveyed in the rails 8 as to inject superhigh pressure water. Since the conveying passage of the rails 8 is flat except the portions of windows 14, 15, even if the superhigh pressure water is injected to the work 4, the work 4 is supported by the surface. Accordingly, the deformation of the work 4 is extremely small to prevent a chip from being damaged.
