Abstract: PURPOSE:To inhibit generation of polycrystallization, twin crystallization and disloca tion defect and to obtain single crystal which has uniform diameter and is excellent in crystallinity by specifying the position of the communicating hole of a coracle in the device wherein the coracle is floated on the melt of a raw material. CONSTITUTION:Both melt 7 of a raw material in a crucible 4 supported by a rotatable and raisable lower shaft 5 and a liquid sealing agent 6 covering the melt are heated by a heater 8 wherein radiation of heat outward is prevented by a heat insulating material 9. A coracle 10 is floated to interface part of melt 7 and the sealing agent 6. In this device, for example, the coracle 10 is formed of a reverse conical shape and the communicating holes 10a are formed to the bottom. The positions thereof are set in the vicinity of the outer circumferential part of melt 7a in the coracle. Seed crystal 2 fitted to the tip of the upper shaft 1 provided to the upper part of the crucible 4 is immersed in the surface of melt 7a. The shafts 1, 5 are rotated in the direction shown in the arrows and the shaft 1 is pulled up and crystal is grown. In this device, the temp. of the outer circumferential part of melt 7a can be raised and therefore the shape of the solid-liquid interface is made even or made a convex shape projected to the lower part and thereby the aim is attained.

Title: Gas discharge device
Inventor: KURIFUOODO ROBAATO UEZARATSUTS
IPC: H01J17/50
Filed: 1989-02-15
Abstract: PURPOSE: To increase the amount of ionizing in a device by making a path length of a charged particle of discharge when a magnetic field exists longer than that when a magnetic field does not exist. CONSTITUTION: A magnetic field generated in a thyratron by a magnet 5 is substantially parallel in the direction perpendicular to surfaces of a cathode 3 and an anode 2 as shown by a broken line indicating a line of magnetic force. Electrons are emitted from the cathode 3 while operating the thyratron. The electron which does not progress in the direction parallel to the magnetic field traces a spiral path around the line of magnetic force, and is pulled to a grid by an electric field applied to the grid. Each electron which progresses along the spiral path has a lot of chances to do ionized collisions when it moves toward the grid 4 and the anode 2. As a result, an ionized density in the device increases.

Title: Dynamic image encoder
Inventor: NAKASHIKA MASAHIRO
IPC: H04N19/00
Filed: 1997-02-20
Abstract: PROBLEM TO BE SOLVED: To warrant consistency and continuity of image quality as a whole of video images in the case that encoding is conducted while adaptively selecting a pre-filter characteristic. SOLUTION: Cut border information of an input image signal obtained by advance encoding (preliminary scanning) or the like and a cut commonality classification code are stored in a cut classification information storage section 106. A pre-processing control section 105 in this coding uses the information to employ the same pre-filter characteristic designation parameter for a plurality of cuts with high commonality characteristics and controls the changeover of the pre-filter characteristic designation parameter at the cut border. Thus, the pre-filter characteristic is not changed on the way of processing of the same cut and the same pre-filter characteristic is applied to cuts with high commonality characteristics (under the same recording condition) apart timewise so as to keep consistency and continuity of image quality over whole video images.
