Title: Printing and recording device
Inventor: WADA TASAKU
IPC: B41J25/24
Filed: 1980-12-23
Abstract: PURPOSE: To make it possible to perform accurate printing on recording paper having a specified width by using an endless type belt which accommodates types, by arranging a plurality of type lines in parallel on the type belt and shifting the type lines in the direction perpendicular to the type lines.  
     CONSTITUTION: Frames 15 and 16 hold pulleys 10 and 11 and are shifted in the direction perpendicular to the type lines together with the type belt 1 in response to the rotation of a shift motor 23. Meanwhile, printing hammers 2, whose number is the same as the number of the printing digits in one printing line, are arranged at the opposite positions to the types of the type belt 1, with the same interval as the interval between the printing digits being provided. When a electromagnet 22 is selectively energized, the printing hammer 21 flies to the surface of the type in the type belt 1, and hits the surface of the type through ink ribbon 48. Thus the printing is performed.

Abstract: PROBLEM TO BE SOLVED: To enhance the quality of a III-V compound semiconductor containing nitrogen and In by specifying the variation in the concentration of In atom within a specified region from the surface of an InN layer. SOLUTION: Assuming the thickness of an InN growth layer 123 is (t), variation in the concentration of in atom is set within ±15% in a region of 0.2t-0.6t from the surface of InN growth layer. More specifically, In is distributed uniformly in an active layer and the quality of a III-V compound semiconductor 123 containing nitrogen and In is enhanced. When 1,4-diazobicyclo (2, 2, 2) octane is used as the source of N at the time of vapor phase epitaxial growth of III-V compound semiconductor 123 containing nitrogen and In, melting point is set in the range of 158-160 deg.C and sublimation takes place at a temperature lower than the melting point. Since a low temperature vapor phase epitaxial growth is realized and thermal diffusion of In is controlled, the ratio of concentration (α) between N and In can be sustained constant (within ±15% for some value).
