Abstract: A terminal according to one aspect of the present disclosure includes a receiving section that receives a channel state information reference signal (CSI-RS), and a control section that performs, by using a machine learning model trained based on first configuration of the CSI-RS, control of performing prediction based on second configuration of the CSI-RS. According to one aspect of the present disclosure, high-accuracy channel estimation, high-efficiency use of resources, and the like can be implemented.

Abstract: A radio communication node includes a connection unit capable of connecting with multiple radio communication nodes having a same or different function or role, and controls connection performed by the connection unit.

Abstract: The radio relay device controls a relay state when a radio wave from a radio base station or a terminal is relayed without signal interpretation. The radio relay device transmits or receives a signal related to detection or identification to/from the radio base station or the terminal.

Abstract: A communication device includes: a transmission unit configured to transmit a connection request to a first communication device; a reception unit configured to receive connection permission from the first communication device; and a control unit configured to establish a first connection to the first communication device. The control unit controls a communication of a second communication device, and the reception unit receives recommendation information related to installation of the device itself from the first communication device.

Abstract: A communication device includes: a transmission unit configured to transmit a connection request to a first communication device; a reception unit configured to receive connection permission from the first communication device; and a control unit configured to establish a first connection to the first communication device. The control unit controls a communication of a second communication device, and the transmission unit transmits information related to control of the second communication device to the first communication device in a case where the connection to the first communication device is established.

Abstract: A communication device includes: a transmission unit configured to transmit a connection request to a first communication device; a reception unit configured to receive a connection permission from the first communication device; and a control unit configured to establish a first connection to the first communication device. The control unit controls a communication of a second communication device and performs a communication with the second communication device, and the second communication device performs a communication with a third communication device that includes: a transmission unit that transmits a connection request to the first communication device; a reception unit that receives a connection permission from the first communication device; and a control unit that establishes a first connection with the first communication device.

Abstract: A pump system contains a pair of pumps each of which contains a vibration actuator vibrated by electromagnetic drive and can discharge fluid due to drive of the vibration actuator. The pump system has a vibration suppression mode in which the pair of the pumps are driven so that vibration of the vibration actuators of the pair of pumps is cancelled each other and a vibration generation mode in which the pair of the pumps are driven so that the vibration of the vibration actuators of the pair of pumps is superimposed with each other.

Abstract: A tap 1 has a threaded portion 2 including a cutting blade 5 on an outer circumferential surface, a flute portion 3 that divides the threaded portion 2 in a circumferential direction, and a shank portion 4 formed continuously from the threaded portion 2 and the flute portion 3 along a central axis O. The flute portion 3 includes, in a cross-sectional view, a first flute 31 formed continuously from the cutting blade 5 of the threaded portion 2, a second flute 32 formed continuously from the first flute 31, and a ridge line portion 33 being a boundary between the first and second flutes 31, 32. A distance “e” from the central axis O to the ridge line portion 33 is longer than a distance d1 and a distance d2, respectively.

Abstract: A container includes a container body which is cylindrical and includes an opening portion, the container body having a container body rib on at least a portion of an outer peripheral surface of the opening portion, and a lid member coupled to the container body by a hinge such that the lid member is openable and closable relative to the opening portion of the container body. The lid member has a sidewall positioned such that the lid member externally contacts the opening portion when the lid member is closed. The sidewall has an inner side surface having a lid rib which the container body rib contacts and slides over in opening or closing the lid member. The container body and the lid member are structured such that in closing the lid member, before the container body rib contacts and slides over the lid rib, no part of the opening portion other than the container body rib comes into contact with the lid member.
