  • Patent number: 11923266
    Abstract: A semiconductor module circuit structure, including an insulating circuit substrate having an insulating plate, and a circuit pattern formed on a top face of the insulating plate, and a semiconductor element disposed on a top face of the circuit pattern. The circuit pattern includes a first straight part extending in a first direction, a second straight part extending in a second direction different from the first direction, and a corner part connecting the first and second straight parts. A wiring member is formed on a top surface of the first straight part along the first direction, the wiring member being formed off-center at the first straight part to be closer to an outer periphery of the circuit pattern.

    Abstract: A semiconductor device includes a semiconductor chip, a bonding member, and a planar laminated substrate having the semiconductor chip bonded to a front surface thereof via the bonding member. The laminated substrate includes a planar ceramic board, a high-potential metal layer, a low-potential metal layer, an intermediate layer. The planar ceramic board contains a plurality of ceramic particles. The high-potential metal layer contains copper and is bonded to a first main surface of the ceramic board. The low-potential metal layer contains copper, is bonded to a second main surface of the ceramic board, and has a potential lower than a potential of the first main surface of the high-potential metal layer. The intermediate layer is provided between the second main surface and the low-potential metal layer and includes a first oxide that contains at least either magnesium or manganese.

  • Patent number: 11631622
    Abstract: A semiconductor device, including a substrate having an insulating plate and a conductive plate formed on the insulating plate, a semiconductor chip formed on the conductive plate, a contact part arranged on the conductive plate with a bonding member therebetween, a rod-shaped external connection terminal having a lower end portion thereof fitted into the contact part, and a lid plate having a front surface and a back surface facing the substrate. An insertion hole pierces the lid plate, forming an entrance and exit respectively on the back and front surfaces of the lid plate. The external connection terminal is inserted in the insertion hole. The semiconductor device has at least one of a guide portion with an inclined surface, fixed to a portion of the external connection terminal located in the insertion hole, or an inclined inner wall of the insertion hole.

  • Publication number: 20220355976
    Abstract: A holder for a bottle excellent in handleability is provided. A holder of the present invention is a holder for holding, in an internal space, a bottle having a body part larger than a neck part below the neck part. The holder includes a bottom part; a top part having an opening smaller than a sectional size of the body part; and a grip portion extending in a height direction of the holder between the bottom part and the top part. A state of the holder is switched between a first state and a second state. In the first state, a portion of the holder is detached and separated from another portion of the holder, and hence the internal space is opened. In the second state, the bottom part supports a bottom surface of the bottle in the internal space, the grip portion is positioned beside the bottle, and the neck part protrudes from the opening.

  • Patent number: 10199314
    Abstract: A flange on first open end of a tubular contact member is soldered to a conductive plate of an insulating substrate. An external electrode terminal is fitted into a main body tube portion of the tubular contact member. The tubular contact member includes a protrusion that protrudes inwardly from an inner wall of the main body tube portion. The protrusion is disposed along the entire perimeter of inner wall toward the first open end. The protrusion has a thickness deformation of the protrusion by a load applied thereto when the external electrode terminal is pressed into the main body tube portion. The protrusion is disposed at a height that can block solder that climbs the inner wall of the main body tube portion, to form a gap between the protrusion and a lower end of the external electrode terminal inserted to a predetermined depth of the main body tube portion.
