Title: Kazuhiro Oyama: Innovator in Computer Systems and Power Semiconductor Technology

Introduction

Kazuhiro Oyama is a prominent inventor based in Hadano, Japan. He has made significant contributions to the fields of computer systems and power semiconductor technology. With a total of 4 patents to his name, Oyama continues to push the boundaries of innovation in his industry.

Latest Patents

Oyama's latest patents include a computer system and data input/output method. This invention features a storage apparatus that includes multiple ports communicable with a server, multiple processor cores, and multiple Logical Units (LUs). Each port is assigned a port responsible core, which accepts I/O requests, while each LU has an LU responsible core for I/O tasks. Notably, the LU responsible core can be dynamically changed, allowing for greater flexibility. The server periodically acquires identification information about the LU responsible cores from the storage apparatus. When transmitting an I/O request, the server selects a non-cross call path to ensure efficient communication between the LU responsible core and the port responsible core.

Another significant patent by Oyama is a power semiconductor module and its fabrication method. This invention utilizes an elastic printed board designed to absorb stress applied by silicon gel. The printed board is narrow enough to allow stress to escape, while high-voltage wires are patterned on separate printed boards to prevent discharge. This innovative design enables the power module to be hermetically sealed, preventing moisture intrusion and ensuring durability against displacement, transformation, and cracks.
