A clamping jig according to the present disclosure includes a supporting portion extending in a vertical direction, and a bent portion connected to a top side of the supporting portion and configured to come into contact with an outer peripheral portion of a substrate. The bent portion includes a base end portion located on a side of the supporting portion and a tip portion connected to the base end portion. At least the tip portion contains a ceramic containing silicon carbide or aluminum oxide as a main component.

Clamping jig and cleaning device

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 Rδcin a roughness curve of an inner wall surface of the tubular portion is smaller than a cut level difference Rδcin 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.

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&#x394;q) on the light-receiving surface in a roughness curve is larger than an average value of root mean square slope (R&#x394;q) on the back surface.

Position detecting member

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.

Coil component and inductor

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.

Heat storage

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.

Vacuum suction nozzle for component mounting apparatus

A golden-colored sintered product having a high hardness, strength, Young's modulus (rigidity) and excellent oxidation resistance and corrosion resistance and is useful as a sliding material, golden-colored ornamental material exhibiting beautiful color tone and as an abrasion-resistant material for such applications as a wall material, a timepiece material, brooches, necklaces, medals, buttons, fishing tools and the like, and to a method of preparing the same. The golden-colored sintered product has, as constituent elements, at least titanium, nitride and boron, and comprises 67 to 78% by weight of titanium, 6 to 15% by weight of nitrogen and 6.5 to 21.0% by weight of boron, wherein the carbon content is 3% by weight or smaller, titanium nitride and titanium boride are present as crystal phases in said sintered product, and crystal grains of said titanium nitride are linked to each other like chains.
