Abstract: PURPOSE:To inexpensively obtain the abrasive grains coated with a diamond film and having the performance equivalent to the conventional diamond abrasive grains by vibrating a holder carrying abrasive grains to rotate the grains, and depositing diamond on the grain surface by vapor-phase synthesis. CONSTITUTION:The raw gas (H2+CH4) is introduced from the upper part of a reaction tube 10, and discharged 6 from the lower part. A holder 3 carrying the abrasive grains 11 to be coated is set in a reaction chamber 9 by a supporting rod 2. A microwave oscillated by a microwave oscillator 7 is injected into the chamber 9 through a waveguide 8 to produce spherical plasma around the holder 3. Meanwhile, an exciting rod 12 is vibrated by an exciter 1 to vibrate the rod 2, and the holder 3 is further vibrated. The abrasive grains 11 on the holder 3 are rolled without being shifted in the lateral direction by the vibration of the holder 3. By this method, diamond can be uniformly synthesized by vapor-phase synthesis, and deposited on the surface of the grain 11.

Title: Three-dimensional image display device
Inventor: MORI KOSHIRO
IPC: H04N13/04
Filed: 1996-09-04
Abstract: PROBLEM TO BE SOLVED: To obtain a three-dimensional display device by which a stereoscopic picture can be seen at a wider visual angle than a conventional one by using a dynamic image splitter that consists of a liquid crystal display panel that can reverse the transparency and shading of light. SOLUTION: A right eye does not see optional pixels 7 and 8 on a TV screen at certain intervals by a shading part of a dynamic image splitter 4. In such cases, a left eye can see the pixels 7 and 8 through the light transmitting part of the splitter 4. On the other hand, at the next interval when the light transmitting and shading parts of the splitter 4 are reversed, states in which the right and left eyes can see are reversed to each other. While the right eye can see the pixels 7 and 8, the left eye can not see them. Even if the right and left eyes relatively change their positions against a three-dimensional image display device, a constant area where the eyes can recognize an image as a stereoscopic picture exists. Therefore, a stereoscopic picture can be recognized at a wider visual angle than a conventional device.

Thus the image information is received after the its error is corrected. A storage device 207 stores the moving images which are sent from the end of the video source in the time trace-back direction. A stream control circuit 208 monitors the time stamps which are sent from both devices 205 and 206 and releases the real-time calls of high quality when the non-real time information is coincident with the real-time information.

Abstract: PURPOSE:To decrease the quantity of reinforcing materials to a greater extent and to improve electrical characteristics by arranging the reinforcing materials to a specific shape on a disk surface in such a manner that a magnetic head can be supported at least at 3 points. CONSTITUTION:The reinforcing materials 3 on the disk 1 are so disposed to the prescribed position that the magnetic head, disposed in direct contact with the disk surface, can be supported at least at the 3 points. For example, the reinforcing materials 3 are disposed concentrically, spirally or radially at specified intervals by using a lithographic technique. While 10<10> pieces of the reinforcing materials exist in the conventional random arrangement, the quantity can be greatly decreased to half said pieces; i.e., 10<5> pieces in this method. The chipping away of the foreign matter stuck to the head is effectively satisfied and the improvement in the electrical characteristics is attained.
