There is provided a flow pipe including: a pipe body including a side wall having an opening portion; and a heat insulator arranged at an inner peripheral side of the pipe body and having a flow path through which a fluid flows. The heat insulator has an outer peripheral surface facing with the side wall, and the outer peripheral surface has a flow path structure configured to form a flow path that guides a water droplet generated between the heat insulator and the pipe body to the opening portion.

Flow pipe

An optical tweezers device includes: an acquisition unit which acquires basic movement information indicating a movement of a stage; a conversion unit which converts the movement of the stage indicated by the basic movement information into a movement of a particle being trapped and generates converted movement information indicating the movement of the particle; and a distance calculation unit which determines a distance between the particle being trapped by the laser beam and a focal point of the lens. The conversion unit generates the converted movement information by correcting the movement of the particle using the distance determined by the distance calculation unit.

A thermoacoustic cooling device includes a tube in which a working fluid is enclosed; a first stack that generates acoustic waves in the working fluid with use of a temperature gradient; a first high-temperature heat exchanger provided at a first side of the first stack to heat the first side of the first stack; a first low-temperature heat exchanger provided at a second side of the first stack; a second stack in which a temperature gradient is generated by the acoustic waves; a second high-temperature heat exchanger provided at a first side of the second stack, which has a high temperature; a second low-temperature heat exchanger provided at a second side of the second stack, which has a low temperature; and a heat transfer portion configured to connect the second low-temperature heat exchanger to the first low-temperature heat exchanger so as to transfer heat therebetween.

Thermoacoustic cooling device

In a conveying device, a belt conveyer is equipped with a conveying portion that conveys an object from an upstream region to a downstream region. A heat source heats the conveyed object. A cooling portion is located downstream of a terminal end of the belt conveyor and cools the object. A first thermoacoustic cooling device cools the cooling portion. A first prime mover generates acoustic waves from heat transmitted from the first heat source. A first receiver generates, from the acoustic waves, cooling heat corresponding to a cooling temperature that is lower than a temperature of the heat source.

Conveying device

A thermoacoustic device includes a loop pipe, a first stack that is disposed in the loop pipe and that generates a sound wave in the loop pipe by way of a temperature gradient, a second stack that is disposed in the loop pipe and that generates a temperature gradient, a first high temperature side heat exchanger that is disposed at one end of the first stack and that makes the temperature of the one end of the first stack be higher than the other end, and a first low temperature side heat exchanger that is disposed at the other end of the first stack and that makes the temperature of the other end of the first stack be lower than the one end.

Thermoacoustic device

An optical tweezers device determines trapping force data indicating a trapping force for a particle on the basis of a distance between the particle trapped by focusing laser beam with a lens and a focal point of the lens. The optical tweezers device determines a difference between a trapping force theoretical value that is estimated according to a linear relationship between the distance between the trapped particle and the focal point of the lens and the trapping force for the particle and the trapping force indicated by the trapping force data. The optical tweezers device controls a laser power of the light source on the basis of the difference of the trapping force.

A machine tool includes a thermoacoustic apparatus and a fluid supply apparatus, utilizes exhaust heat from a constituent apparatus of the machine tool to cool a heat exchanger included in the thermoacoustic apparatus due to a thermoacoustic effect. Thus, a cooling fluid is cooled which is used to cool a bearing and a machining point.
