Filed: 1995-05-30
Abstract: PURPOSE: To provide a file access control system for parallel processing system by which the throughput of processing of data can be improved and the simultaneous executability of data processing can be improved by reducing overhead due to the exclusive control of file. CONSTITUTION: In a parallel processing system for simultaneously performing access from respective hosts through a shared buffer 50 to a shared file 60, when updating a page, a shared file access means 20 sets information showing an updating person onto a reference buffer 51 and prepares the page of a new version on an update buffer 52 without updating any existent page on the reference buffer, so that page reference and update can be simultaneously executed. The information showing the number of reference persons is set onto the reference buffer 51 and used for opening the reference buffer. Thus, lock control for the unit of a page is unnecessitated, reference and update can be processed in parallel, and waiting time due to the exclusive control is reduced.

Abstract: PURPOSE:To form a highly efficient semiconductor laser of buried multi-quantum well type of simple structure and easy manufacture by forming a layer of high carrier concentration at least to a part of a clad layer and by making a cut-off layer which holds one conductivity type after impurity introduction. CONSTITUTION:A second clad layer 5 consists of two layers of different carrier concentration. The side in contact with an active layer 4 is an n<+> type AlxGa1-xAs cut-off layer 51 of high carrier concentration and the upper layer is an n-type AlxGa1-xAs clad layer 52. Carrier concentration is set at, for example, 5X10<17>cm<-3> for the clad layer 52 and 3X10<18>cm<-3> for the n<+> type cut-off layer 51. A carrier concentration of an n-type GaAs cap layer 6 is set at about 1X10<-8>cm<-3>. A voltage is applied so that an n-type electrode 81 becomes negative and p type electrode 82 becomes positive in this structure. At a Zn diffusion region 93, a p-type first clad layer 31 and a p-type second clad layer 54 are electrically cut off by an n-type cut-off layer 53; therefore, a current can not flow up and down the Zn diffusion region and is constricted in a non-diffusion region to center in the active layer 4.

Title: Semiconductor laser
Inventor: KAMITE KIYOTSUGU
IPC: H01S5/12
Filed: 1989-06-20
Abstract: PURPOSE:To restrain the relaxation oscillation of a semiconductor laser without lessening it in extinction ratio and to prevent the occurrence of a chirping phenomenon by a method wherein the width of a mesa stripe is made to change in stages keeping the width of an active layer constant. CONSTITUTION:The width of a mesa stripe 9 or the contact part of the mesa stripe 9 with an electrode 7 are made to change in stages along a resonator direction, that is, it is narrow at an A-A' section side and wide at a B-B' section side. On the other hand, an active layer 5 is kept constant in width on both the section sides. As the width of the active layer 5 is constant on both the A-A' section side and the B-B' section side but the A-A' section side and the B-B' section side are different from each other in width of the mesa stripe 9, the width of a contact area between the electrode 9 and a contact layer 8 on the A-A' section side becomes narrow due to a current construction layer 4 as compared with that on the B-B' section side. Therefore, the A-A' section side becomes small in density of injected carriers as compared with the B-B' cross section side. By the difference of injected carrier density, a relaxation oscillation can be restrained when pulses are applied.
