Publication number: 20240051850Abstract: [Problems] To implement UVC energy irradiation at a unified amount to a target for sterilization and decomposition of all in a fluid that is flowing, by greatly increasing a depth of a fluid that receives radiation from a UVC light source significantly to increase a rate at which UVC energy per unit irradiates the target of sterilization and decomposition in the fluid, in continuous sterilization of fluids by UVC irradiation in a container optically shielded from the outside.Type: ApplicationFiled: June 30, 2021Publication date: February 15, 2024Inventor: Nobuo Oyama

Publication number: 20230382770Abstract: [Problem] To obtain a functional structure of a UVC irradiation container that allows uniform fluid movement velocity throughout the entire area of the container without causing a “flow passage” to form even when the amount of fluid in the UVC irradiation container is greatly increased, thereby enabling uniform UVC irradiation. Solution A continuous sterilization method in which a rectangular body-shaped UVC irradiation container is properly fitted with dividing walls to form a single fluid flow consisting of multiple layers of horizontally aligned flows over the entire UVC irradiation area of the container, which is then irradiated with UVC from its inner wall side.Type: ApplicationFiled: October 13, 2021Publication date: November 30, 2023Inventor: Nobuo Oyama

Patent number: 7843639Abstract: A plurality of structures each having a number of ridges and being formed in a long and thin plate shape or a long and thin film shape. The cross section of each of the ridges forms a portion of a substantial circle and a surface thereof is a practically specular surface. The ridges of each structure are parallel to each other and respective adjacent surfaces thereof correspond to each other in parallel and are spaced apart from each other at a predetermined distance. When light is incident on a point of a surface of one of the structures at an incident angle, in either its reflection or transmittance, the light is diffused in a circular conical plane whose vertex is the incident point and whose center axis is a line parallel to the ridges, by a diffraction effect caused by the arrayed ridges. The flux of reflected diffused light is spread in one lengthwise half of the circular conical plane and the flux of transmitted diffused light is spread in the other lengthwise half of the circular conical plane.Type: GrantFiled: March 6, 2007Date of Patent: November 30, 2010Assignee: Kabushiki Kaisha S.T.I.

Patent number: 7828018Abstract: Four light-transmitting mono filaments each having an almost circular cross section and surface substantially being mirror surface are arranged in a single layer and in parallel, and a flat yarn formed by fusing or melt-bonding adjacent mono filaments to each other and fixing them is twisted. Twisting is imparted over a full length of a light diffusing yarn continuously at a frequency of more than one time with a length five times as long as the width of the flat yarn. The twisting cyclically reverses the front and rear surfaces of the flat yarn along the longitudinal direction of the light diffusing yarn to continuously change the longitudinal-axis direction of each mono filament along the longitudinal direction of the light diffusing yarn.Type: GrantFiled: May 1, 2007Date of Patent: November 9, 2010Assignee: Kabushiki Kaisha S.T.I.

Patent number: 6966673Abstract: A light distribution control device including a substantially plate-like or film-like light diffusion structure which transmits or reflects light and at least one surface of which has a number of ridges arranged parallel to each other. The section of each ridge taken in a direction perpendicular to the longitudinal direction substantially constitutes a part of a circle, the surface of each ridge being smooth enough not to cause significant irregular diffusion of light. The ratio of diffraction light quantity to incidence light quantity is adjusted through selection of the angle of circumference and maximum diameter of the section of each ridge. The projection of diffusion distribution onto a plane perpendicular to both the longitudinal direction of the ridges and the surface of the structure is substantially symmetrical with respect to the normal at the point of incidence independently of the angle of incidence of the light.Type: GrantFiled: September 7, 2001Date of Patent: November 22, 2005Assignee: Kabushiki Kaisha S.T.I.
