A lid body includes a base containing an alloy of iron and nickel, a first film positioned on a lower surface of the base and containing nickel, and a second film positioned on a lower surface of the first film and containing copper. During welding of the lid body, penetration of crystal grain boundaries of the base by Cu of the second film is reduced by the first film. Therefore, occurrence of cracks in the base is reduced and thus a package with high airtightness can be formed.

Lid body, electronic component accommodation package, and electronic device

A spectrum control device includes a control unit that obtains spectrum information. The control unit controls at least one of a spectrum of light emitted by a light emitting device or a spectrum of image light that forms an image, on the basis of the spectrum information.

Spectrum control device, non-transitory computer readable medium, and data structure

A board in an aspect of the present invention includes a substrate, a first film, a first layer, and a second film. The substrate has a first elastic modulus. The first film is at an upper surface of the substrate. The first layer is at a lower surface of the substrate. The first layer has a second elastic modulus lower than the first elastic modulus and has a first thermal expansion coefficient. The second film is at a lower surface of the first layer. The second film includes the same material as the first film and has a second thermal expansion coefficient lower than the first thermal expansion coefficient.

Board and semiconductor apparatus

Provided are a packaging sheet and a packaging container where it is unnecessary to paste a printed label and disappearance or color development due to friction or the like after thermal printing do not occur. The packaging sheet includes a heat seal layerfor thermally welding by heating, a heat-sensitive layerincluding a color developing material that develops a color by heating, and a base material layerthat secures the strength and protects the heat-sensitive layer. The heat seal layer, the heat-sensitive layer, and the base material layerare provided in this order from a back surface side in a thickness direction. The packaging sheet is transparent before the heat-sensitive layerdevelops the color.

A thermosensitive recording body has at least a thermosensitive recording layer and a topcoat layer formed on a substrate. The substrate consists of a transparent film. At least the thermosensitive recording layer and the topcoat layer includes a diffuse reflection suppressor component that suppresses diffuse reflection of light from particles constituting the thermosensitive recording layer and the topcoat layer.

Thermosensitive recording body

There is provided a transparent adhesive sheet on which printing can be performed during in use and which has high transparency, while including an adhesive layer on the back surface side and a release layer on the front surface side. The transparent adhesive sheet includes: a base material layer formed with a transparent material; an adhesive layer formed on the back surface side of the base material layer and formed with an adhesive agent for bonding to an adherend; a recording layer formed on the front surface side of the base material layer and containing a color developing material that thermally develops color; and a release layer formed on the further front surface side of the recording layer and having release properties to the adhesive agent. The transparent adhesive sheet is transparent in the state before the recording layer develops color.

Transparent adhesive sheet

[Problems] Provided is a thermal recording sheet in which both a thermal recording layer having developed color and a printed layer can be clearly recognized from the front surface side of the sheet. [Solution] A thermal recording sheet having a front surface and a back surface opposite the front surface includes: a substrate layer; a recording layer formed on the front surface side of the substrate layer and containing a color developing material that develops color by heating; a protective layer formed on the further front surface side of the recording layer; and a printed layer formed on the back surface side of the recording layer. In a state before the recording layer develops color, a portion containing the recording layer and the protective layer and formed on the front surface side to the printed layer is transparent.

Thermal recording sheet

A communication apparatus includes an NFC circuit, an FM receiver, a level detector, and an NFC control circuit. The NFC circuit is configured to make wireless communication with a communication apparatus of a communication partner using a specified communication frequency. The FM receiver is configured to adjust a radio reception range to a band including a multiplied frequency of the communication frequency. The level detector is configured to detect a reception level of the band when the FM receiver receives the band including the multiplied frequency. The NFC control circuit is configured to control the NFC circuit to reduce transmission power in the NFC circuit when the reception level is smaller than a predetermined threshold value.

Communication apparatus and control method

A portable electronic device includes a communication request receiving unit which receives a communication request from another communication device, a display unit which displays an image based on image data, an input unit which is provided to overlap with the display unit and detects an input of a user, a determination unit which determines whether the image is being displayed on the display unit when the communication request receiving unit receives the communication request, an input determination unit which determines whether a predetermined input is detected by the input unit when the determination unit determines that the image is being displayed, and a display control unit which displays information for starting a communication with the other communication device on the display unit when the predetermined input is detected by the input unit.
