An oral tool is provided that includes a body and a measurement unit. The measurement unit is disposed in a movable configuration with respect to the body, and includes a sensor unit at an end opposite to an end where the body is disposed. The sensor unit is constructed to be inserted into a mouth. The end of the measurement unit opposite to the end where the sensor unit is disposed is disposed inside the body. The oral tool includes a stress reliever disposed between the measurement unit and the body at a portion where the measurement unit changes a distance from the body while moving.

A fluid control device includes a fluid conveying element formed by a pump and a valve, and an outer housing containing the fluid conveying element. The outer housing includes a first outer wall forming an internal space closer to the pump, and a second outer wall forming an internal space closer to the valve. The second outer wall includes an outer-wall main plate having a part overlapping, in plan view, a through hole that is a discharge hole of the valve. A thermal conductivity of the part of the outer-wall main plate overlapping the discharge hole is higher than a thermal conductivity of the first outer wall.

An oral tool is provided that includes a body, a measurement unit, and a flow stopper. The measurement unit is moveable relative to the body, and includes a sensor unit at an end opposite to an end where the body is disposed. The sensor unit is constructed to be insertable into a mouth. Moreover, the flow stopper is disposed between the measurement unit and the body, and has a surface with a curvature different from a curvature of a surface of the measurement unit.

A pump includes a housing, a first vibrating body, a second vibrating body, and a peripheral wall portion that define a pump chamber, and a driving body. The housing has a first wall portion opposed to the first vibrating body and a second wall portion. The first wall portion includes a first concave portion that opens toward the first vibrating body and opposed to a central portion of the first vibrating body and a first circumferential portion adjacent to the first concave portion. A first chamber includes a first wide portion defined by the first concave portion and the first vibrating body, and a first narrow portion defined by the first circumferential portion and the first vibrating body. The first narrow portion overlaps with at least part of the first vibrating body.

Piezoelectric pump with an upper and lower vibrating body

A gas control device includes a pump, a valve, a cuff, and a controller. The valve includes a first plate having a first vent hole and a first vent hole, a channel forming plate having an exhaust hole and an exhaust channel, a second plate having a second vent hole, and an edge separation plate. A manchette rubber tube in the cuff is joined to the periphery of the second vent hole in the second plate by an adhesive, and thus the valve is connected to the cuff. The exhaust hole is opened to the atmosphere. The pump includes a pump housing having a discharge hole and a discharge hole. The upper surface of the pump housing is joined to the bottom surface of the edge separation plate.

Valve, gas control device, and sphygmomanometer

A valve includes a first valve housing, a second valve housing, a diaphragm, a first fixing part, and a second fixing part. The diaphragm defines an upstream valve chamber together with the first valve housing. The diaphragm defines a downstream valve chamber together with the second valve housing. The diaphragm is movable between a first position in which the diaphragm blocks communication between the upstream valve chamber and the downstream valve chamber, and a second position in which the diaphragm allows communication between the upstream valve chamber and the downstream valve chamber. When in its second position, the diaphragm makes contact with the inlet of the second discharge channel or the wall surface of the downstream valve chamber to seal between the second discharge channel and the first discharge channel, and when in its first position, the diaphragm allows communication between the first discharge channel and the second discharge channel.

Valve, and fluid control device including valve

A vapor chamber that includes a housing having a first sheet and a second sheet that oppose each other and of which respective peripheral regions are joined to each other to form a sealing portion. The vapor chamber also includes a working liquid enclosed within the housing and a wick structure on an inside surface of the first sheet or the second sheet. In the vapor chamber, the sealing portion includes a first portion having a first width and a second portion having a second width, the first width being greater than the second width. A specially shaped portion is present in the first portion. The specially shaped portion is a portion at which an inclination angle of the first sheet and/or the second sheet is greater than a second inclination angle of a portion of the first sheet and/or the second sheet outside of the specifically shaped portion.
