摘要： A laminate includes: a first laminate member; a second laminate member; and a hidden print formed by printing invisible ink between the first laminate member and the second laminate member. The hidden print is configured to absorb electromagnetic radiation outside the visible range. When irradiated with electromagnetic radiation outside a visible range that has passed through at least one of the first laminate member and the second laminate member, the hidden print absorbs the electromagnetic radiation to thereby show a sign, and, when irradiated with visible light, the hidden print does not show the sign.

摘要： Display regions each include a plurality of reflection surfaces. The reflection surfaces are arranged at an average pitch of 1 µm and 300 µm inclusive in a direction in which the reflection surfaces are arranged. The display regions of each display region group include display regions that differ from one another in the normal direction of the reflection surfaces. Each display region group is configured to form, in the associated observation direction, an image that is unique to the display region group and composed of the image elements formed by the display regions of the display region group.

摘要： A cell transplantation device is used to place a graft containing cells into a target region in a living body. The cell transplantation device includes a needle extending in one direction, and a filter unit made of a fibrous member. The needle has a flow channel defined therein and an opening at the tip of the needle. The filter unit is disposed at an intermediate position in the flow channel and configured to retain a graft between the filter unit and the opening when a liquid material containing the graft enters the flow channel through the opening.

摘要： A light control sheet includes a light control layer and two transparent electrodes sandwiching the light control layer. In the light control sheet, absolute values of one or more target change ratios have a maximum value of 0.7 or more, each target change ratio being a change ratio of a light-shielding ratio [%] with respect to an applied voltage [V] in a target range, the target range being a range of the applied voltage in which a light-shielding ratio of the light control sheet changes by 10%, the light-shielding ratio being prescribed by JIS L 1055:2009.

摘要： There is provided a microfluidic device (1) including a flow path (35), and one or more droplet holders (11) connected to the flow path (35). In the microfluidic device (1), the flow path (35) has a height of more than 0 µm and 30 µm or less. There is also provided a sample analysis method that uses the microfluidic device (1). The method includes introducing a sample-containing aqueous solution into the flow path and allowing the droplet holders to accommodate the aqueous solution, introducing a sealant into the flow path for replacement with the aqueous solution present in the flow path and encapsulating the aqueous solution in the droplet holders, causing a reaction in the droplet holders and generating signals for detection, and detecting the signals.

摘要： A laminate (10) includes a recording layer (11), a translucent front covering layer (12) and a security foil (20) laminated between the recording layer and the front covering layer and sealed in the laminate. The security foil has a thickness that is 1/5 or less the thickness of the recording layer to prevent or reduce falsification reusing the security foil. The security foil includes a relief layer (21) having a relief surface and a protective layer (22) covering the relief surface. In the thickness direction of the laminate, the protective layer adheres to the recording layer and the relief layer adheres to the front covering layer. The adhesion strength between the security foil and the recording layer is higher than the adhesion strength between the security foil and the front covering layer.
