    • A process for producing a single-crystal semiconductor and an apparatus therefor. A single-crystal semiconductor of large diameter and large weight can be lifted with the use of existing equipment not having any substantial change thereto while not influencing the oxygen concentration of single-crystal semiconductor and the temperature of melt and while not unduly raising the temperature of seed crystal. In particular, the relationship (L1, L2, L3) between the allowable temperature difference (ΔT) and the diameter (D) of seed crystal (14) is preset so that the temperature difference between the seed crystal (14) at the time the seed crystal (14) is immersed in the melt and the melt (5) falls within the allowable temperature difference (ΔT) at which dislocations are not introduced into the seed crystal (14). In accordance with the relationship (L1, L2, L3), the allowable temperature difference (ΔT) corresponding to the diameter (D) of seed crystal (14) to be immersed in the melt is determined. Temperature control is conducted so that at the time the seed crystal (14) is immersed in the melt (5) the temperature difference between the seed crystal (14) and the melt (5) falls within the determined allowable temperature difference (ΔT).

    • For minimizing spark energy and improving durability of a spark plug (13) without controlling a time for energizing a primary wiring (L1); the ignition unit (1,2 and 3) for an internal combustion engine is arranged in that actions of a transistor (17) are controlled by an ECU (19) to abruptly interrupt a primary current (i1) such that high voltage for ignition induced to a secondary wiring (L2) is applied on the spark plug (13) for generating spark discharge. For forcibly interrupting spark discharge at a spark discharge duration, the ECU (19) switches the thyristor (21 and 210) ON to supply current to the primary wiring (L1) for forcibly interrupting the spark discharge. By controlling the spark discharge duration to be optimum on a basis of an operating condition of the internal combustion engine, it is possible to restrict generation of multiple discharge and to restrict exhaustion of electrodes of the spark plug (13). It is also possible to realize spark discharge through a simple arrangement of low cost by simply providing a single thyristor (21 and 210).
