IPC: B41J19/18
Filed: 1982-08-23
Abstract: PURPOSE:To contrive to enhance an average printing speed through an optimum speed control, by a method wherein times of generation of a type selection completion signal and a carriage printing position arrival signal are discriminated, and a speed required for selecting a type in a table is renewed. CONSTITUTION:The time of generation of the signal R indicating the completion of selection of a type by a type wheel W which signal is fed from a printing part 10 through a mechanical controlling part 9 and the time of generation of the signal S indicating the arrival of a printing head H at a printing position are discriminated by a discriminating part 5. When the signal R is generated prior to the signal S, a timer 6 is started, and when the signal S is not outputted before the time is up, an adder 7 is operated through a checking part 8 so that type selection speed information according to a type position angle read from the table T is added with +1, and renewed speed is written into the table T. When the signal S is generated prior to the signal R, subtraction and renewing are performed in a similar manner. By this system wherein the speed is not fixed but is renewed, the type selecting speed is always made to be optimum so that the signal S is outputted immediately after the signal R is outputted, and the average printing speed is enhanced.

Abstract: PURPOSE:To grow the second GaAs single crystal substrate by effecting recrystallization of Ge with interposing a fluoride insulating layer of high melting point on a GaAs single crystal substrate. CONSTITUTION:A part of GaAs single crystal substrate 11 on which semiconductor elements 12 are arranged is covered with SiO2 13 and CaF2 20 is vapor- deposited on the substrate to 0.1-0.3mum with a substrate temperaure of 400- 600 deg.C to form a single crystal layer 21 and a polycrystalline layer 32. Subsequently, Ge 30 is vapor-deposited to 1mum with a substrate temperature 400 deg.C to form a single crystal layer 31 and a polycrystalline layer 32. Nextly, the Ge polycrystal 32 is recrystallized with the adjacent Ge single crystal 31 as a seed by a zone melting method.

By this constitution, even if the recrystallization is done with such temperature that the GaAs single crystal and Ge polycrystal enter into a reaction completely, a GaAs single crystal is laminated easily by recrystallization of Ge because a Ge thin layer is arranged with interposing a fluoride insulating layer.
