Abstract: An electronic device includes a connector and a power feed circuit. The connector includes a plurality of first terminals. The plurality of first terminals are connected to a plurality of second terminals of a connecting device and include: one or more power supply terminals to supply direct-current power to the connecting device; and a detection terminal. When the connecting device is connected to the connector, the power feed circuit determines whether a second terminal, among the plurality of second terminals, connected to the detection terminal is a specific terminal. The power feed circuit supplies direct-current supply power having a voltage value set based on a result of the determination to the connecting device via the one or more power supply terminals of the connector.

Abstract: A ladder program display device displays an operation status of a ladder program executed by a sequence controller, in which a self-holding circuit is extracted from the ladder program, a signal address used in the extracted self-holding circuit is set as a signal address to be traced, and the display of a result of tracing the signal address by the sequence controller is outputted.

Abstract: In a semiconductor device, a lower chip includes a first group of connection terminals provided on a straight region including a corner region and a region extending from the corner region along one side. An upper chip includes a second group of connection terminals. The upper chip and the lower chip are arranged so that the first group of connection terminals at least partially overlaps with the second group of connection terminals. The first group of connection terminals is at least partially electrically connected to the second group of connection terminals.

Abstract: In a semiconductor device (1), a lower chip (20) includes a first group of connection terminals (26) provided on a straight region (34) including a corner region (32) and a region extending from the corner region along one side. An upper chip (10) includes a second group of connection terminals (12). The upper chip (10) and the lower chip (20) are arranged so that the first group of connection terminals (26) at least partially overlaps with the second group of connection terminals (12). The first group of connection terminals (26) is at least partially electrically connected to the second group of connection terminals (12).

Abstract: Provided are a novel hydrazide chelate complex compound which is excellent in terms of both solubility in a coating solvent and light fastness, which can be used for blue laser recording, and which is useful as a dye for forming a recording layer of an optical recording medium, the hydrazide chelate complex compound being represented by general formula (1) below; and a dye for forming a recording layer of an optical recording medium, the dye containing the compound. In general formula (1), ring A represents an aromatic ring; R1 and R6 each represent an aromatic ring group or a monovalent nonaromatic ring substituent having 20 or less carbon atoms; R2 to R5 each represent a hydrogen atom, an aromatic ring group, or a monovalent nonaromatic ring substituent having 20 or less carbon atoms; n represents 0 or 1; a represents an integer of 1 to 3; M represents a transition metal atom; and X represents an atom of Groups 14 to 16 of the periodic table.
