  • Publication number: 20240051850
    Abstract: [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.

  • Publication number: 20230382770
    Abstract: [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.

  • Patent number: 7843639
    Abstract: 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.

  • Patent number: 7828018
    Abstract: 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.

  • Publication number: 20100139165
    Abstract: Light emitted from an LED lamp (1) substantially vertically enters the face of the first light diffusion structural member (2) to be diffused within a predetermined plane (P) perpendicular to a longitudinal direction of a linear ridges of the light diffusion structural member (2), and enters the face of the second light diffusion structural member (3) as the flat light flux having a predetermined diverging angle. An incident angle to the second light diffusion structural member (3) varies according to the angle of light, which has passed through the first light diffusion structural member (2). However, light diffusion in the width direction (W) is suppressed by the second light diffusion structural member (3) to be within a range of suitable diffusion angles, and a flat light flux (B) having high directivity is formed.

  • Publication number: 20090077874
    Abstract: Light distributing members (1) are inserted into corresponding multiple openings (7) in ladder tapes (2, 3) and are loosely fitted there. When one ladder tape (2) is pulled upwardly and the other ladder tape (3) is pulled downwardly, respective weft yarns (6) of the ladder tape (2) come into contact with lower surfaces of the corresponding light distributing members (1) to apply an upward lifting force Fl to the light distributing members (1) and respective weft yarns (6) of the other ladder tape (3) come into contact with upper surfaces of the corresponding light distributing members (1) to apply an downward pushing force F2 to the light distributing members (1). Accordingly, each of the light distributing member (1) is held between the weft yarn (6) positioned at a lower end of the each opening (7) of one ladder tape (2) and the weft yarn (6) positioned at an upper end of the each opening (7) of the other ladder tape (3).

  • Patent number: 6966673
    Abstract: 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.
