Abstract: A humidity measuring device is equipped with a temperature and humidity measurement unit including a temperature sensing element that measures temperature and a humidity sensing element that measures humidity, a casing having an accommodating section in which the temperature and humidity measurement unit is accommodated, and a supply tube that supplies a gas at a measurement location into the accommodating section, and a display unit having a display device, and which is fixed to the casing. The display unit further includes a display control unit that controls the display device to thereby cause the display device to display at least one of the humidity of the gas measured by the humidity sensing element, or a dew point temperature of the gas calculated based on the temperature of the gas measured by the temperature sensing element, and the humidity of the gas measured by the humidity sensing element.

Abstract: A pipe inspection system which tests for compressed air leaks in a section to be inspected in a pipe has a first branch pipe and a second branch pipe. The first branch pipe branches from the pipe upstream of the section to be inspected, and joins the pipe, upstream of the section to be inspected. The second branch pipe branches from the pipe downstream of the section to be inspected. The first branch pipe has a fluorescent solvent supply unit provided therein that supplies a fluorescent solvent to the section to be inspected. The second branch pipe has a fluorescent solvent recovery unit provided therein that recovers fluorescent solvent from the section to be inspected.

Abstract: A flow rate control valve includes a handle rotatably provided on a first body including a second flow path, a needle valve that adjusts the opening degree of the second flow path in accordance with the rotation of the handle, a scale body rotatably provided in the handle, a shaft portion provided in the handle, where the shaft portion can rotate together with the handle and the needle valve to move the needle valve in the axial direction, a clutch mechanism that can transmit rotation of the shaft portion to the scale body and block the transmission of rotation, and a cam mechanism that causes the shaft portion to move linearly. The clutch mechanism transmits the rotation of the shaft portion to the scale body in accordance with the operation performed by the cam mechanism and blocks the transmission of rotation.

Abstract: An air chuck includes: a finger support part including a pair of fingers and a pair of lock shafts; a chuck main body part including an operation mechanism operable to open and close the fingers; and linking mechanisms that detachably link the finger support part to the chuck main body part. Each of the linking mechanisms causes the corresponding lock shaft to shift to a non-lock position so as to render the pair of fingers capable of being opened and closed when the finger support part is linked to the chuck main body part. Each of the linking mechanisms causes the corresponding lock shaft to shift to a lock position and locks the pair of fingers so as to render the pair of fingers incapable of being opened and closed when the finger support part is detached from the chuck main body part.

Abstract: An air chuck includes: a finger support part including a pair of fingers; a chuck main body part including an operation mechanism operable to open and close the pair of fingers; and linking mechanisms that detachably link the finger support part to the chuck main body part. The linking mechanisms each include: a linking shaft that extends from the finger support part; a shaft insertion hole formed in a body of the chuck main body part; a catch body that becomes elastically caught on a catch surface of the linking shaft when the linking shaft is inserted into the shaft insertion hole; and a delinking member that is manually operated so as to release the catch body caught on the catch surface when the finger support part is detached from the chuck main body part.

Abstract: A finger includes a pair of overhanging portions that project out laterally from a main body portion. Outer peripheral surfaces of the overhanging portions are made up from five surfaces including upper surfaces, side surfaces, lower surfaces, first end surfaces, and second end surfaces. Crowning is applied to the intersections between these surfaces.

Abstract: In a compressed-fluid discharge control device, there are formed a valve chamber communicated with a discharge channel and supply channels for supplying a compressed fluid, and a pilot chamber into which the compressed fluid is introduced from the supply channels. A diaphragm valve for communicating or cutting off communication of the supply channels and the discharge channel seats on or separates from a valve seat provided in the valve chamber. Pilot channels through which a compressed fluid supplied to the pilot chamber passes are formed in the diaphragm valve. The compressed-fluid discharge control device has a pilot chamber opening/closing valve for opening or closing the pilot chamber. The pilot chamber opening/closing valve includes a solenoid valve which is opened in response to energization thereof and closed in response to de-energization thereof.
