Abstract: A molding die according to the present disclosure includes a tubular portion and a base portion that closes an end portion of the tubular portion at one side. A cut level difference R?c1 in a roughness curve of an inner wall surface of the tubular portion is smaller than a cut level difference R?c2 in a roughness curve of an inner wall bottom portion of the base portion. The cut level difference represents a difference between a cut level at a load length ratio of 25% in a roughness curve and a cut level at a load length ratio of 75% in the roughness curve.

Abstract: A position detecting member includes a base portion including a light-receiving surface having a black color tone and a back surface located on an opposite side to the light-receiving surface. A surface layer portion including at least the base portion is made of ceramic. An average value of root mean square slopes (R?q) on the light-receiving surface in a roughness curve is larger than an average value of root mean square slope (R?q) on the back surface.

Abstract: There is provided a coil component which includes a core; and a plurality of leg portions provided at respective ends of the core, wherein each of the leg portions includes a protrusion which protrudes inward with respect to a joint between the core and the leg portion.

Abstract: Provided is a heat storage including a container including a first container made of ceramics and a second container made of ceramics, the first container and the second container being combined, and a heat storage material housed inside the container. The first container and the second container are bonded via a bonding member. A volume occupied by pores in the first container, in a first contact region including a surface section in contact with the bonding member, is greater than a volume occupied by pores in regions other than the first contact region. A volume occupied by pores in the second container, in a second contact region including a surface section in contact with the bonding member, is greater than a volume occupied by pores in regions other than the second contact region.

Abstract: A mounting member for heat treatment having a mounting surface for a target object includes a zirconia-based ceramic including zirconia crystals, and a columnar body including zirconium as a main component and present on at least a part of the mounting surface.

Abstract: A vacuum suction nozzle operable to reduce or eliminate electronic component blow off and electrostatic damage is disclosed. The vacuum suction nozzle comprises a ceramic body with a first surface at a side opposite to a second surface of the ceramic body. The ceramic body causes static electricity generated on the vacuum suction nozzle to be dissipated to an electronic component mounting device. Dissipation of the static electricity reduces or eliminates electrostatic damage to the electronic component and electrostatic repulsion induced blow off during suction by the vacuum suction nozzle.
