A bar-shaped stainless steel product contains, by mass %, 0.001 to 0.030% of C, 0.01 to 4.00% of Si, 0.01 to 2.00% of Mn, 0.01 to 4.00% of Ni, 6.0 to 35.0% of Cr, 0.01 to 5.00% of Mo, 0.01 to 2.00% of Cu, and 0.001 to 0.050% of N. In the product, an F value is 20 or less, a rolling-direction-crystal-orientation RD//<100> fraction is 0.05 or more, and preferably a rolling-direction-crystal-orientation RD//<334> fraction is 0.2 or less. The above RD//<100> fraction means an area ratio of crystal having 25 degrees or less of an orientation difference between a <100> orientation and a rolling direction, and the above RD//<334> fraction means an area ratio of crystal having 10 degrees or less of an orientation difference between a <334> orientation and a rolling direction. F value=700C+800N+20Ni+10Cu+10Mn−6.2Cr−9.2Si−9.3Mo−74.4Ti−37.2Al−3.1Nb+63.2.

Rod-shaped electromagnetic stainless steel material

Provided are a power transmitting device, a power receiving device, a power supply system, and a power supply method able to supply electric power by emitting electromagnetic waves. A power transmitting device comprises: a calculating unit for calculating the maximum value for the emitted output of electromagnetic waves meeting exposure standards on the basis of a response delay time measured by the communication link between the power transmitting device and a power receiving device; a power transmitting unit for transmitting power via a power supply link with the power receiving device at an output not exceeding the maximum value; an anomaly detecting unit for detecting an anomaly in the power supply link on the basis of communication with the power receiving device via the communication link; and an output control unit for controlling the output on the basis of the detection of an anomaly in the power supply link.

A method, a system, and a computer program product provide for changing a boundary between zones. This includes setting a location of a boundary which defines a part of a zone; detecting that an object moves into the zone across the boundary; and in response to the detection, changing the location of the boundary in a direction away from the object, compared to the location of the boundary before the change.

Dynamic boundary setting

Embodiments include providing content requested by a user via an access point capable of wireless communication. Aspects include receiving the content provided by the management server and storing the content provided by the management server into a volatile memory provided in the wireless communication apparatus. Aspects also include storing difference data into a nonvolatile memory if it is requested to change the content stored in the volatile memory and monitoring a state of communication connection with the access point and whether or not a packet giving an instruction to hold the content has been received. Aspects further include deleting the content stored in the volatile memory if communication with the access point is disconnected or if the packet is unreceived.

Information processing system, wireless communication apparatus, method and program

Transmitting device, receiving device, communication device, programs, transmission method, and receiving method for wireless communication of continuous data in the form of packets. A transmitting device includes a data receiving unit that receives continuous data from a network, the continuous data including actual data and null data; a packetizing unit that deletes at least a part of the null data from the continuous data to generate a packet for wireless communication; a transmitting unit that modulates the packet into a radio carrier wave and wirelessly transmits the resulting packet; and a control unit that causes the transmitting unit to stop transmission of the radio carrier wave during at least a part of a time period in which no such packet is transmitted wirelessly.

Methods and systems for receiving radio frequency (RF) signals include adjusting a digital baseband signal from a first RF front-end to compensate for errors based on a correlation value from a first correlator. A set of digital baseband signals from a set of respective additional RF front-ends is adjusted to compensate for errors based on correlation values from a second correlator. The adjusted digital baseband signal from the first RF front-end and the adjusted set of digital baseband signals from the set of respective additional RF front-ends are combined.
