Abstract: There is provided an optical body, a lighting device, and an image display device that are novel and improved, and can increase a homogeneous light distribution property. The optical body is provided in which a composite structure of main structural bodies is deployed continuously within a plane of a base material, in which phase distributions of the main structural bodies within the plane of the base material are equivalent to amplitude distributions each obtained by subjecting a pupil function of a two-dimensional optical aperture to Fourier transform, and a peak ratio value is less than or equal to 2.5.

Abstract: A plasma processing apparatus includes a plasma process chamber; a substrate support that is disposed in the plasma process chamber and includes a first flow path; an upper electrode assembly that is disposed above the substrate support and includes a second flow path; a first chiller configured to maintain a temperature of a first temperature-controlled fluid at a first temperature, the first temperature-controlled fluid flowing through the first flow path; a second chiller configured to maintain a temperature of a second temperature-controlled fluid at a second temperature, the second temperature-controlled fluid flowing through the second flow path; and a thermoelectric element configured to generate power by a difference in temperature between the first temperature-controlled fluid and the second temperature-controlled fluid.

Abstract: A piping system includes: pipes, each of which is covered with a heat-insulating member and through which a cooling medium flows; and a heat transfer member arranged between two heat-insulating members of two of the pipes adjacent to each other. The heat transfer member includes: a contact portion configured to be in contact with the two heat-insulating members; and a heat-receiving portion including a heat-receiving surface configured to be in contact with outside air outside of the pipes, and configured to transfer heat, which is received from the outside air on the heat-receiving surface, to the contact portion.

Abstract: Disclosed herein is a torque limiter device which is provided with an inner ring and an outer ring and the inner ring and the outer ring operate together to transmit an input torque to an output member constituted of one of the inner ring and the outer ring as long as the torque is not more than a set torque. One of the input member and the output member is provided with an engagement groove, and the other of the input member and the output member is provided with a coil spring for pressing into the engagement groove an engaging member which is to engage with the engagement groove. When the input torque applied to the input member exceeds the set torque level, the engaging member deforms the coil spring to disengage from the engagement groove, resulting in the input torque not being transmitted to the output member.

Abstract: A geared motor includes a drive source, a deceleration transmission mechanism which is connected to the drive source for decelerating and transmitting a rotation output of the drive source to an output part, a first case which fixes the drive source, a second case which forms a space for accommodating the drive source together with the first case and supports the deceleration transmission mechanism, and a third case which covers the deceleration transmission mechanism. A part of the deceleration transmission mechanism is formed with the second case in an integral manner. For example, the deceleration transmission mechanism includes a planetary gear mechanism which comprises a sun gear which transmits the rotation output from the drive source, a planetary gear which revolves around the sun gear while rotating, and an internal gear which is integrally formed on the second case and engages with the planetary gear.

Abstract: A rolled paper feeding device includes a holder body which rotatably supports a rolled paper, a cover part where one end of which is rotatably supported in a contacting and separating direction with respect to the rolled paper and the other end of which abuts with the rolled paper, a feed roller which is provided in the cover part for feeding a paper of the rolled paper, and a drive part which is provided in the cover part for rotationally driving the feed roller. The feed roller is arranged on the other end side with respect to the center of the rolled paper. A control part for controlling the drive part may include a first and a second switches, which can provide three different lengths of the paper to be fed out of the rolled paper.

Abstract: The present invention provides a torque limiter with an easy maintenance feature. It is capable of alignment and bidirectional rotation. The present invention overcomes the problems of torque limiters of conventional technology by providing a torque limiter comprising an inner ring and an outer ring wherein when a torque is applied to an input member, which is inner ring or outer ring, is less than a set torque, the inner ring and the outer ring move in response to each other. Stopper grooves are provided on inner ring or outer ring and a flat spring is provided on inner ring or outer ring such that it pushes roller pins against stopper grooves; wherein when the torque applied to roller pins exceeds a set torque, roller pins cause flat spring to elastically deform such that roller pins come out of stopper grooves. Inner ring and outer ring are thus uncoupled.
