Title: Positioning controller
Inventor: OHASHI TAKEHIRO
IPC: G11B17/22
Filed: 1988-12-19
Abstract: PURPOSE:To attain accurate positioning even if the interval of address is not constant by providing an edge width counter and a logic operation circuit. CONSTITUTION:The edge width counter 10 counts a tacho pulse (d) while an edge detection signal (b) is detected and it outputs the signal of a low level when it reaches a distance equivalent to an edge part when the interval of the address is constant. The output signal maintains the low level while the edge detection signal (b) is detected, and it goes to a high level when the edge detection signal (b) cannot be detected. Then, the edge part is detected by exceeding the distance equivalent to the edge part when the interval of the address is constant and the input of the tacho pulse (d) to a tacho counter 61 is stopped in a section by the operation of the logic operation circuit 20. Thus, accurate positioning is attained even if the interval of the address is not constant.

Next, wire layers 4, 5 in the scanning side and the signal side are formed after an interlayer insulating layer 3 is formed only near the wire crossing part of the wire layers 4, 5 in the scanning side and the signal side to improve the reliability of the wire parts. Finally, a film 6 for electron emitting part formation is formed and electron emitting parts are formed in the film 6 to complete a surface conduction electron emitting element. A pluarlity of elements are simultaneously formed and thus an electron source with simple matrix structure is completed.  Consequently, the number of manufacturing processes is lessened and the electron source is manufactured at low cost by employing a thin film screen printing method.

Abstract: PROBLEM TO BE SOLVED: To enhance the quality of a GaN based compound semiconductor layer while preventing an Si substrate from bending by forming a stress absorption layer of GaAs, a buffer layer of AlGaInN compound having specified composition, and an AlGaInN compound semiconductor layer having specified composition sequentially on an Si substrate. SOLUTION: A stress absorbing layer 2 of GaAs is formed on an Si substrate 1 and a compound buffer layer 3 having composition of Alx Ga1-x-y Iny N (0<=x<=1, 0<=y<=1) is formed thereon followed by formation of a compound buffer layer 4 having composition of Alx Ga1-x-y Iny N (0<=x<=1, 0<=y<=1) further thereon. The buffer layer 3 protects the stress absorbing layer 2 against high temperature at the time of forming a compound semiconductor layer 4 thus preventing the stress absorbing layer 2 from being decomposed. Consequently, stress due to lattice mismatching between the Si substrate 1 and compound semiconductor layer 4 is absorbed by the stress absorbing layer 2.
