Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To provide a novel process for production which efficiently produces a single crystal substrate having a desired shape directly from a raw material with high quality at a low cost in place of the conventional process for slicing the substrate from a bulk single crystalline body and an apparatus for production. SOLUTION: A planar seed 6 cut to a desired bearing is placed in a casting mold in which a planar space is formed by a splittable casting mold base part 1 and a casting mold cap part 2. The raw material 5 is loaded thereon and is heated to form a melt by a heater 3; thereafter, the casting mold is moved downward by a driving device 4 on which the casting mold is placed and is capable of vertically moving the casting mold. The casting mold and the melt therein are thus integrally and slowly cooled and the single crystal is grown.

Filed: 1983-03-30
Abstract: PURPOSE:To enable dynamic change of already set priority order according to the state of data storing of accessed part by providing a circuit that detects inability of taking out data from accessed section more than specified number of times in a specified time. CONSTITUTION:Every time access request is made to a main storage, number of times of access request is counted up by 1 by a detecting circuit 1. When the number of times arrives at a specified number of times in a specified time, an output signal is generated from the circuit 1 and supplied to a priority order determining circuit 2. By this, priority order is dynamically changed so that right of access is given to access request of next priority order instead of giving right of access to a buffer storage (a) to access request of competing highest priority order. Thus, capacity of the system can be improved without generating overrun in a channel.
