A cleaning tool for a collection member includes a brush unit and a mount portion. The brush unit includes a bristle and a woven portion into which a root of the bristle is woven so as to be held by the woven portion. The mount portion includes a placement surface on which the woven portion is placed and a securing portion to which the brush unit is bonded. In the cleaning tool for the collection member, the woven portion includes two first outer surfaces that are located at respective ends of the placement surface and that extend parallel to a direction in which the bristle extends. In the cleaning tool for the collection member, the brush unit is secured to the mount portion by bonding a region that includes at least part of each of the two first outer surfaces to the securing portion with an adhesive.

A walking assistance device includes: a base body; a driving unit that moves the base body; a distance detection unit that detects a distance from the base body to a user; a safety distance range setting unit that set, as a safety distance range, a distance range from the base body to the user during safe walk of the user; a walking state determination unit that determines whether or not the distance detected by the distance detection unit is out of the safety distance range; and a control unit that controls the driving unit when the walking state determination unit determines that the distance is out of the safety distance range. The walking assistance device detects that the distance is narrower than a predetermined distance, wherein the driving unit is controlled when the approach determination unit detects that the distance is narrower than the predetermined distance.

Walking assistance device

There is provided a particle detector that can increase a detection sensitivity to fluorescence emitted from biogenic particles. A particle detector for detecting biogenic particles includes a substrate having a principal surface and configured to collect the biogenic particles on the principal surface, a light emitting element configured to irradiate particles collected on the principal surface with excitation light, and a light receiving element configured to receive fluorescence emitted from the particles when the particles are irradiated with the excitation light from the light emitting element. An optical axis of the Fresnel lens and a ray direction of the excitation light intersect with each other. The principal surface is a mirror surface.

Particle detector

A particle detection device detects a biological particle. The particle detection device includes a collection unit that collects a particle to a collection substrate, a fluorescence detection unit that emits excitation light toward the particle collected on the collection substrate and receives fluorescence emitted from the particle, and a cleaning unit that removes the particle from the collection substrate at a refreshing position separated from a collection/heating position and a detection position. At the collection/heating position, the particle is collected onto the collection substrate by the collection unit. At the detection position, fluorescence is received by the fluorescence detection unit. With such a structure, the particle detection device in which the particle is highly accurately detected is provided.

Particle detection device

A Fresnel lens includes an incident surface that is flat, and a prism-forming surface that has a plurality of prisms, the prism-forming surface being provided on the side of the Fresnel lens opposite to the incident surface. Each of the prisms has a converging surface that is located on the side away from the optical axis of the Fresnel lens.

A method for forming an electrode plate for a battery includes the steps of (a) forming mixture layers on a current collector, lateral end surfaces of the mixture layers forming a continuous plane with at least one lateral end surface of the current collector; and (b) forming a porous film on the mixture layers. The step (b) includes the steps of: (b1) placing an electrode plate including the current collector and the mixture layers on a gravure roll having a cylindrical part and a truncated cone part provided continuously on an end surface of the cylindrical part to have an outwardly increasing inside diameter, the location of the end surface of the truncated cone part near the cylindrical part corresponding to the location of the continuous plane; and (b2) after the step (b1), abutting the gravure roll against the moving electrode plate while rotating the gravure roll in the opposite direction to the direction of travel of the electrode plate, thereby continuously applying a coating fluid serving as a precursor of the porous film to the electrode plate to cover longitudinal surfaces of the mixture layers and the continuous plane.

One end of an FPC () for supplying power to the driving section of a light amount control section provided in a shutter unit () is disposed between a second lens holder () and the shutter unit () secured to this second lens holder () and is held between the second lens holder () and the shutter unit (). Thus, the FPC () is prevented from being spaced apart from the shutter unit (), and a member for securing the FPC () to the shutter unit () is eliminated, reducing the number of part items. Further, the second lens holder () and the shutter unit () blocks unwanted light toward the FPC (), so that a ghost image is prevented from appearing on an image due to unwanted light reflected on the FPC ().
