Title: Haruko Shiraishi: Innovator in Rotary Machine Technology

Introduction

Haruko Shiraishi is a prominent inventor based in Tokyo, Japan. She has made significant contributions to the field of rotary machine technology, holding 2 patents that showcase her innovative designs and engineering skills.

Latest Patents

One of her latest patents involves a rotary machine that includes damper pins and platforms, each having a flat surface extending in an axial line direction. For each adjacent pair of platforms, a damper abutting surface of the first platform extends toward a damper abutting surface of the second platform, approaching the outer side of a rotor blade stage in a radial direction while opposing each other in a peripheral direction. A damper accommodation space is defined between each adjacent pair of platforms, which is created by the surfaces including the damper abutting surfaces. Each damper pin is designed as a regular polygonal prism extending in the axial line direction, with an angle defined by two side surfaces corresponding to the angle defined by the damper abutting surfaces.

Another patent by Shiraishi describes a rotary machine where one of the platforms has a first abutting surface extending in a radial direction against which damper pins abut. This rotary machine includes a first moving member that is movable in the peripheral direction between the adjacent platforms. The moving member features a second damper abutting surface that interacts with the damper pins, while a spring member biases the first moving member toward one side in the peripheral direction.
