Abstract: A switching circuit including: a switching device configured to conduct or open a state between a drain terminal and a source terminal; a drive circuit including a first switch element and a second switch element, the drive circuit being configured to open and close the first switch element and the second switch element, and output a drive voltage for driving the switching device to the gate terminal via an output end; a clamp circuit including a third switch element configured to conduct between a reference potential of the drive circuit and a connection point of a path connecting the output end of the drive circuit and the gate terminal; and a ferrite inductor provided immediately near the output end of the drive circuit, and having one end connected to the output end and the other end connected to the connection point.

Abstract: A driving circuit for a switching element that drives a switching element of a current-driven type. The driving circuit includes a controller including a first terminal and a second terminal and that outputs a control signal to a gate terminal of the switching element. A first resistor, which regulates a current serving as the control signal, is connected to the first terminal, and a first capacitor is connected in parallel to the first resistor. A second resistor and a second capacitor are connected in parallel, and a current path extends from the first resistor and the first capacitor to the gate terminal and from a source terminal of the switching element to the second terminal of the controller. The second resistor and the second capacitor are in the current path.

Abstract: A conveyance seat includes a cushion frame. The cushion frame includes side frames disposed on right and left sides in a seat width direction, and a pan frame (connecting frame) connecting the right and left side frames. The side frames includes respective engagement protrusions (engaging portions) that engage with engagement recesses (engaged portions) provided in the pan frame, to position the pan frame. The engagement protrusions are formed to protrude toward an engagement recess side in a facing direction (up to down direction) in which the side frames and the pan frame face each other. The engagement recesses engage with the respective engagement protrusions by coming into contact with the respective engagement protrusions in an intersecting direction intersecting with the facing direction.

Abstract: The present invention provides: a mutant of adeno-associated virus (AAV) capsid protein, which contains at least one amino acid substitution in PLA2 domain when compared with the amino acid sequence for wild-type AAV capsid protein; a nucleic acid encoding the mutant; a cell containing the nucleic acid; a method for producing a recombinant AAV particle, comprising a step of culturing the cell to produce the recombinant AAV particle; a recombinant AAV particle containing the mutant; a composition containing the recombinant AAV particle; and a method for transferring a gene into a target cell, comprising a step of bringing the recombinant AAV particle into contact with the target cell.

Abstract: In a diversity antenna apparatus, chip antennas are used as antenna elements, and the chip antennas are disposed in association with a ground pattern with certain gaps from the ground pattern. The chip antennas are disposed so as to surround the ground pattern formed on a substrate, and the ground pattern is shared among the chip antennas. Furthermore, hybrid patterns are included in the substrate, and the hybrid patterns also share the ground pattern with the chip antennas to achieve compact design. Alternatively, a transmitting chip antenna and a ground pattern associated with the transmitting chip antenna together form a vertically polarized antenna, and the transmitting chip antenna and the ground pattern associated with the transmitting chip antenna are separated from receiving chip antennas and a ground pattern associated with the receiving chip antennas.
