Title: Method for controlling floating melting zone of semiconductor rod
Inventor: IKEDA YASUHIRO
IPC: H01L21/208
Filed: 1987-04-27
Abstract: PURPOSE:To enable prevention of uplift, connection and cutting by variation in zone length and nonuniformity of semiconductor rod resistivity on the crystallized side, by controlling the zone length which is the length in the axial direction of a melting zone in producing a straight drum part of a semiconductor rod on the crystallized side. CONSTITUTION:The target diameter (Dno) of a neck part is set by a setter 40 for the diameter of the neck part. The detected diameter (Dni) of the melt neck part and target diameter (Dno) of the melt neck part are respectively fed from an image processing circuit 32 and the setter 40 for the diameter of the neck part to a differential amplifier 42, compared amplified and fed to a PID controller 43. Detected values of the rotational speed of a variable speed motor 26 for lifting and lowering by a speed detector 45 are compared with output values of the PID controller 43, amplified by a differential amplifier 44 and as an actuating signal fed to a speed regulator 46. Thereby the rotational speed of the variable speed motor 26 for lifting and lowering is regulated through a driving circuit 47 and controlled so that the diameter (Dni) of the melt neck part may be the target diameter (Dno). As a result, control is carried out so as to indirectly keep the zone length (L) at a constant value in producing the straight drum part.

Filed: 1997-04-22
Abstract: PROBLEM TO BE SOLVED: To see that this pad for skyrocket does not injure human body even if it is let alone on the ground or a beach and that this does not break the environment by making it of polyvinyl alcohol resin which has specified viscosity average polymerization degree and is thermofusable. SOLUTION: The resin used for the bad for fireworks is polyvinyl alcohol resin, and it is obtained by saponifying vinyl ester after polymerizing or compolymerizing it. For the degree of saponification, 40-100 mol.% is desirable, taking the strength, tenacity, and solubility in water of a firework pad into consideration, though there is no special limitation so long as it is thermofusable. It is necessary for the degree of polymerization of resin needs to be 200-2000, and 250-1500 is preferable, and for the quantity of added filler, 0.1-300 pts.wt. to 100 pts.wt. of PVA resin is desirable. Hereby, it is high in modulus in flexural elasticity at use, and even if it is let alone on the ground or a beach, it never injures human body or environment.
