Title: Haruka Yamaji: Innovator in Microstructure Manufacturing

Introduction

Haruka Yamaji is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of microstructure manufacturing, holding a total of three patents. His innovative approaches have advanced the technology surrounding photosensitive resin compositions.

Latest Patents

One of Haruka Yamaji's latest patents is a method for manufacturing microstructures that include cured products of photosensitive resin compositions. This method involves forming at least two layers of photosensitive resin compositions, each containing a photopolymerization initiator. The process includes patterning exposure and collectively developing the exposed layers to obtain a microstructure. Notably, 90% by mass or more of the photopolymerization initiators in at least one of the adjacent layers is a nonionic photopolymerization initiator.

Another significant patent is for producing an epoxy resin composition. This composition contains an epoxy resin, a solid basic compound, and a polythiol. The method ensures that the dissolution of the solid basic compound into the polythiol is rate-limited, which helps maintain the pot life. The catalyst action from the solid basic compound during heating allows for rapid heat curability.
