Abstract: A refrigeration cycle apparatus (1) is capable of performing a refrigeration cycle using a small-GWP refrigerant. The refrigeration cycle apparatus (1) includes a refrigerant circuit (10) and a refrigerant enclosed in the refrigerant circuit (10). The refrigerant circuit includes a compressor (21), a condenser (23), a decompressing section (24), and an evaporator (31). The refrigerant contains is a small-GWP refrigerant.

Abstract: A drive device (7) that unwinds, in a first direction, a wire (WR) connected to an operation target (41, 551, 552) with predetermined tension and pulls the wire in a direction opposite to the first direction to cause the operation target to perform an action includes a motor (71), a first rotating member (74) that can be rotated by the motor in a second direction and in a direction opposite to the second direction about a rotation axis (Rx5), a pulling member (TM) that is provided rotatably coaxially with the first rotating member, holds an end (WR1) of the wire, rotates in the second direction to unwind the wire in the first direction, and rotates in the direction opposite to the second direction to pull the wire in the direction opposite to the first direction, and a pulling member side urging member (77) that urges the pulling member in the direction opposite to the second direction relative to the first rotating member, in which, when the wire is moved in the first direction due to an external factor, the

Abstract: Provided is a communication system including a controller installed on a hand of a user, an operation target remotely operated by the controller, and a relay apparatus that performs relaying between the controller and the operation target, in which the controller includes a first detection section that detects a motion of fingers of the user, a stimulus providing section that provides an external stimulus to the fingers of the user, and a control section that controls the stimulus providing section, the operation target includes a driving section that performs an action in reference to action information received, and a second detection section that detects the external stimulus to the operation target, and the relay apparatus transmits, to the operation target, the action information based on a detection result from the first detection section, and in reference to a detection result from the second detection section, transmits, to the controller, stimulus provision information for controlling the stimulus pr

Abstract: Disclosed is an operation device that includes a mounting section, a first position detection section, and a stimulus generation section. The mounting section is attached to a hand and fingers of a user. The first position detection section is disposed on the mounting section to detect the positions of the fingers. The stimulus generation section is disposed on the mounting section, placed at a position corresponding to one of the user's fingers, and configured to apply an external stimulus to the user.

Abstract: An engine decompressor includes a decompressor pin provided through a pin hole on the surface of a valve cam, a decompressor pin operating shaft in an oil passage provided in a valve cam shaft of the valve cam for vertically moving the decompressor pin by its rotation, a fly weight rotatable by rotation of the valve cam shaft so as to rotate the decompressor pin operating shaft, and a thrust receiving plate separate from the fly weight for restricting the axial movement of the decompressor pin operating shaft in the oil passage. The engine decompressor is capable of operating a decompressor mechanism normally even if the lubricating oil increases in pressure.
