A method of producing a shaped object includes preparing a formation sheet that includes a base and a thermally expansive layer that is laminated on a first main surface of the base, the thermally expansive layer containing a binder and a thermal expansion material; laminating, onto a second main surface on a side opposite to the first main surface of the base or onto the thermally expansive layer, a thermal conversion layer in predetermined pattern, the thermal conversion layer converting first electromagnetic waves into heat; and causing the thermally expansive layer to expand in a pattern that corresponds to the predetermined pattern by irradiating the formation sheet on which the thermal conversion layer is laminated with the first electromagnetic waves and second electromagnetic waves that cause the binder to become cross-linked.

Shaped object production method and expansion device

A shaped object includes a first shaped portion expressing a three-dimensional shape of an object in a first state by at least one bump on the surface of a first thermally expansive section that expands due to being heated, and second shaped portion expressing a three-dimensional shape of the object in a second state by at least one bump on the surface of a second thermally expansive section that expands due to being heated. The second state is a state in which the object is more deteriorated than in the first state. The height of the at least one bump on the surface of the second thermally expansive section at least partially differs from a height of the at least one bump on the surface of the first thermally expansive section.

A node includes a time difference measurement unit and a time setting unit. The time difference measurement unit measures a time difference between a first time based on latest received time information and a second time based on second-latest received time information. The time setting unit calculates an adjustment time difference when the time difference exceeds an allowable range of error that is smaller than an allowable range of maintainable communication, sets a time obtained by adding the adjustment time difference and the second time to the time of the node when the adjustment time difference is within the allowable range of maintainable communication, and sets a time obtained by adding a time difference corresponding to the allowable range of maintainable communication and the second time to the time of the node when the adjustment time difference exceeds the allowable range of maintainable communication.

The nodes each include a link quality evaluating unit, an upstream route constructing unit, a communicating unit, and a downstream route constructing unit. The link quality evaluating unit performs route evaluation using a hello frame based only on a track record of reception of the hello frame in order to perform upstream communication toward the specific node to form a network. The upstream route constructing unit constructs an upstream route based on the route evaluation. The communicating unit performs upstream communication toward the specific node on a regular basis with a predetermined frequency. The downstream route constructing unit constructs a downstream route from the specific node based on a route in the upstream communication toward the specific node.

The selecting unit selects a route request frame to be transferred to another communication device based on the quality information, from the route request frames received by the receiving unit through a plurality of routes. The transfer control unit transfers the route request frame selected by the selecting unit to the another communication device, and discards the route request frame when a quality value indicated by the quality information of the route request frame is smaller than a predetermined reference value.

Communication device and communication control method

A wireless communication device in a data collection system starts measuring a time when the wireless communication device receives a wireless signal from a data collection device. The wireless communication device changes the wireless channel, transmits a detection signal for detecting the data collection device, and starts measuring a time after transmitting the detection signal when the wireless communication device is unable to receive a next wireless signal from the data collection device even after passage of a predetermined time since the wireless communication device has previously received the wireless signal. The wireless communication device changes the wireless channel to be used, depending on whether the wireless communication device has received a response signal from the data collection device in response to the detection signal within a predetermined time.
