Title: Hiroshi Sakamoto: Innovator in Optical Technology
Introduction
Hiroshi Sakamoto is a notable inventor based in Osaka, Japan. He has made significant contributions to the field of optical technology, holding a total of 5 patents. His work has focused on enhancing the functionality and efficiency of optical devices.
Latest Patents
One of Sakamoto's latest patents is an optical disk controller that sets the sampling interval according to the rotational speed of the optical disk. This invention reduces the frequency of output of status reports, thereby relieving the burden on the system controller. The optical disk controller includes a status generator that produces status reports representing the operation state of the controller for each sector of a disk. Additionally, a status sampling section samples these reports at a predetermined interval. If a generated status report matches a 'sampling abort' status stored in a sampling category, the status sampling is aborted.
Another significant invention by Sakamoto is a program modification device. This device allows for the modification of a program that is fixedly recorded in a ROM or similar medium. It enables desired positions in the program to be modified with minimal hardware. The program modification device consists of a modifying address register that stores the addresses of program data to be modified before execution. It also includes a modifying address storage table that pairs the addresses of modification source programs with their corresponding modification target programs.
