[Problem] To provide a reflection device that can retroreflect light incident thereon from a wide range. [Solution] This reflection device for retroreflecting light with which the reflection device is irradiated comprises a retroreflective unit formed by arranging retroreflective reflectors enabling the retroreflection. The retroreflective unit comprises a plurality of reflective regions in which the direction of retroreflection is set to different directions.

BUILDING ASSISTANCE METHOD AND BUILDING ASSISTANCE SYSTEM
Provided is a building assistance method that enables a worker to adjust a building structural material as quickly and appropriately as possible while minimizing labor costs. On the basis of a design value for a built-in building structural material and a measured value obtained via a surveying instrument, a correction amount and a correction direction for the component core of the building structural material are calculated to display a correction guide image. A worker operates an adjustment jig on the basis of the correction guide image. After the correction amount and the correction direction have been calculated by using a prism mode to collimate markers initially installed on the building structural material, the collimation direction of the surveying instrument is set to a design position for the component core, and a process of calculating the correction amount and the correction direction on the basis of non-prism survey data surveyed in a non-prism mode and imaging data captured at the time is repeated.
The present invention is provided with a melting part (40) for heating, melting, and discharging a rod-shaped hot-melt adhesive (50) introduced therein, the melting part (40) is formed of metal, and an introduction port (80a) for introducing the rod-shaped hot-melt adhesive (50) and a discharge port (83a) for discharging the heated and molten liquid hot-melt adhesive (50) are communicated by a plurality of passages (81b). The surface area of contact between the hot-melt adhesive (50) and the melting part (40) is thereby increased, and the hot-melt adhesive (50) can therefore be efficiently heated/melted, heated to a bonding temperature thereof in a short time, and discharged.

WOUND-BODY MANUFACTURING METHOD AND MANUFACTURING DEVICE
This method includes: supporting a mother roll (10) in a state in which there is virtually no resistance to rotation; applying a frictional force to a belt-shaped object (42) that contacts rotating drive rollers (30 and 31); supplying the belt-shaped object (42) from the mother roll (10) to one of the drive rollers (30) via said frictional force alone; moving the belt-shaped object (42) so as to follow the rotation of said drive roller (30); causing the belt-shaped object (42) to roll up on the surfaces of the drive rollers (30 and 31) via only the torque produced by the rotation of the drive rollers (30 and 31); winding the belt-shaped object (42) into a wound body (40) via the aforementioned rolling-up motion; and supporting the wound body (40), by means of the drive rollers (30 and 31), in a state in which there is virtually no resistance to rotation. The belt-shaped object (42) is wound under virtually no tension. The belt-shaped object (42) is a knitted fabric for wiping off ink adhered to the surface of an inkjet nozzle.

A polishing base material (10) comprises a flexible base material (20), a cushion layer (30) formed on one side of the flexible base material (20) and made of a material more elastic than the flexible base material (20), and a nano fiber layer (40) formed on the cushion layer (30). By using the polishing base material (10), texture processing for a magnetic recording medium can be carried out with a polishing material finer than the conventional ones, while ensuring mechanical strength sufficient as a polishing base material. Consequently, texture processing for a magnetic recording medium can be carried out with higher precision than before. When the polishing base material (10) is employed as a base material for wiping, film cleaning or varnishing for a magnetic recording medium can be carried out with higher precision than before.
Provided is an ultra-low dust stir-up wiping material (10) comprising a flexible backing material (20), a first nano-fiber layer (30) formed on one face of the flexible backing material (20), and a second nano-fiber layer (40) formed on the other face of the flexible backing material (20). The ultra-low dust stir-up wiping material has its end faces subjected to a no-dust treatment. The ultra-low dust stir-up wiping material (10) can remove fine dust of a nano size, and can suppress the formation of lint from the wiping material itself. The ultra-low dust stir-up wiping material (10) can be suitably used for an ultra-low dust stir-up wiping material for a clean room.
