Patent JP-H01138768-A (JP)
Title: Light-emitting diode array
Inventor: KOIZUMI YOSHIHIRO
IPC: H01L21/76
Filed: 1987-11-25
Abstract: PURPOSE:To separately drive several light emitting diodes by a method wherein the light-emitting spot regions are electrically insulated from each other by grooves penetrating through a second clad layer, an active layer, and a first clad layer to reach a semi-insulating substrate. CONSTITUTION:Through an electrode 12 built on a groove so deep as to reach a first clad layer 14 through a semi-insulating substrate 13, carriers are implanted into the first clad layer 11. When the first clad layer 14 is an N-type, there will be a 5OMEGA resistance at the highest in a first clad layer 14 even when a light-emitting spot region 10 is but 50mum thick, when minority carriers will be implanted from the first clad layer 14 to the light-emitting spot region 10 of an active layer 15. The carriers coming from the electrode 12 cannot arrive at a neighboring light-emitting element, blocked by a groove 21. Carriers implanted from an electrode 19 are effectively constricted by an insulating film 18, and are implanted into the light-emitting spot region 10 through a second clad layer 16. The light generated at the light-emitting spot region 10 goes through the semi-insulating substrate 13 to be converged by a monolithic lens 11 before being emitted outward.

Title: Task generation/erasure control system
Inventor: MATSUMOTO HIROSHI
IPC: G06F9/48
Filed: 1986-12-16
Abstract: PURPOSE:To utilize the memory effectively by generating a specific task on request of a host program, and releasing the task at a point of time of the execution of all host programs using the task in common is finished so as to make the task transient. CONSTITUTION:A host program supervisory task 8 is resident in a memory to supervise the presence of host programs (A1-An)3 to use the task 2. Thus, even when a host program execution end notice 6 is sent at the end of execution of the host program (A1)3, the host program supervisory task 8 does not issue the host program execution end notice 6 to the operating system 1 till the other host programs (A2-An)3 completes the execution. The operating system 1 does not erase the task 2 from the memory until it receives the host program execution end notice 6. Thus, the other host programs (A2-An)3 use the task 2.
