20110155051 | MANUFACTURING APPARATUS AND MANUFACTURING METHOD OF SILICON CARBIDE SINGLE CRYSTAL - A manufacturing apparatus for growing a SiC single crystal on a surface of a seed crystal that is made of a SiC single crystal substrate by supplying a source gas of SiC from a lower side of a vacuum chamber toward the seed crystal includes a pedestal, a rod member, and a cooling system. The pedestal is disposed in the vacuum chamber. The pedestal has a first surface on which the seed crystal is disposed and a second surface opposed to the first surface. The rod member holds the pedestal. The cooling system includes a temperature control pipe and a coolant temperature controller. The temperature control pipe is disposed on the second surface side of the pedestal. The coolant temperature controller controls a temperature of a coolant that flows to the temperature control pipe. | 06-30-2011 |
20120152165 | APPARATUS AND METHOD FOR MANUFACTURING SILICON CARBIDE SINGLE CRYSTAL - An apparatus for manufacturing a silicon carbide single crystal grows the silicon carbide single crystal on a surface of a seed crystal made from a silicon carbide single crystal substrate by supplying a material gas for silicon carbide from below the seed crystal. The apparatus includes a base having a first side and a second side opposite to the first side. The seed crystal is mounded on the first side of the base. The apparatus further includes a purge gas introduction mechanism for supporting the base and for supplying a purge gas to the base from the second side of the base. The base has a purge gas introduction path for discharging the supplied purge gas from the base toward an outer edge of the seed crystal. | 06-21-2012 |
20120152166 | APPARATUS FOR MANUFACTURING SILICON CARBIDE SINGLE CRYSTAL - An apparatus for manufacturing a silicon carbide single crystal grows the silicon carbide single crystal on a seed crystal by supplying a material gas from below the seed crystal. The apparatus includes a heating container and a base located in the heating container. The seed crystal is mounded on the base. The apparatus further includes a first inlet for causing a purge gas to flow along an inner wall surface of the heating container, a purge gas source for supplying the purge gas to the first inlet, a second inlet for causing the purge gas to flow along an outer wall surface of the base, and a mechanism for supporting the base and for supplying the purge gas to the base from below the base. | 06-21-2012 |
20140123901 | SILICON CARBIDE SINGLE CRYSTAL MANUFACTURING APPARATUS - A silicon carbide single crystal manufacturing apparatus includes a vacuum chamber, a pedestal on which a seed crystal is disposed, an inlet of source gas, a reaction chamber extending from a bottom surface of the vacuum chamber toward the pedestal, a first heating device disposed around an outer periphery of the reaction chamber, a second heating device disposed around an outer periphery of the pedestal, and an outlet disposed outside the first and second heating devices in the vacuum chamber. After the source gas supplied from the reaction chamber is supplied toward the pedestal, the source gas is let flow outward in a radial direction of the silicon carbide single crystal between the reaction chamber and the silicon carbide single crystal and is discharged through the outlet. | 05-08-2014 |

20120294171 | COMMUNICATION DEVICE - A plurality of frame buffers of a communication device store input frames for respective flows, which are units of managing communication. A sequential scheduler and an adjustment scheduler cyclically visit the plurality of frame buffers to read a frame for external output from each frame buffer. The sequential scheduler reads one frame per a visit to each frame buffer at a speed lower than a communication speed of the communication device. The adjustment scheduler reads one or more frames per a visit to each frame buffer such that a restriction on read quantity defined by a reference value greater than the shortest frame size is imposed. | 11-22-2012 |
