Abstract: A multi-die stack structure including N dies stacked vertically is described. N is an integer larger than or equal to 2. Each die includes N die-specific input pads, wherein a specific pad among the N pads is for the input of the die. The specific pad of each die above the bottom die is electrically connected with a different pad of the bottom die other than the specific pad of the bottom die, via at least one TSV and, when not being in the die neighboring to the bottom die, also via a different pad of each underlying die above the bottom die. The specific pad of the bottom die is electrically connected with at least one pad of the overlying die(s) that is not the specific pad of any overlying die and not any pad electrically connected with the specific pad of any overlying die.

Abstract: U-shaped cores and fasteners are embedded in resin members, and brackets provided at respective ends of the fasteners protrude from the resin members. By fixing the brackets and a casing with screws, a reactor main body and the casing are fixed together. Openings formed by a partition wall that suppresses a direct application of a resin flowing from resin-filling portions to the fasteners are provided between the respective fasteners and the respective resin-filling portions. A protrusion extending in an opposite direction to a core and in parallel with the partition wall is provided between the resin-filling portions and the partition wall. The resin flowing from the resin-filling portion flows in between a core upper face and the fastener, and between a fastener surface located behind the partition wall and the internal surface of a die.

Abstract: An electronic sphygmomanometer determines whether a position of a measurement site falls within a proper range, and notifies whether the position of the measurement site falls within the proper range. When determination is made that a time in which the position of the measurement site falls within the proper range is not less than a predetermined time (for example, 2 seconds), measurement of a blood pressure is automatically started. When determination is made that a time in which the position of the measurement site is out of the proper range is not less than a predetermined time (for example, 5 seconds), the measurement of the blood pressure is started. Further, whether the position of the measurement site falls within the proper range is notified while correlated with the measurement result.
