Abstract: Provided are a technique with which a satin-like appearance can be obtained in nickel-plating by a nickel-plating additive characterized by containing a benzethonium salt, a satin nickel-plating bath containing the same, and a satin nickel-plating method using the same.

Abstract: An object of the present invention is to provide a silicon oligomer having a novel function that has not been achieved by a conventional condensation product of water and a tetraalkoxysilane. Provided are a silicon oligomer represented by the following formula (I) and a production method therefor: wherein R1 to R10 each independently is an alkyl group or a hydroxyalkyl group, each having 1 to 4 carbon atoms; X1 to X3 each independently is a group represented by the following formula (II); n is 0 or 1; and m is an integer of 1 to 3 when n is 0, and m is 1 when n is 1: wherein A is an alkylene group having 2 to 4 carbon atoms which may be branched, and 1 is an integer of 1 to 3.

Abstract: A receiving part (2) has a substantially rectangular shape with short sides and long sides, and its short-side inner surface (15) is provided with a central latch claw (32) in a substantially central region thereof with respect to a short side direction, with side elastic latch portions (33) provided on both sides of the central latch claw (32) with respect to the short side direction. Each of the side elastic latch portions (33) includes a receiving-part rib (34), an elastic piece (35), and a side elastic latch claw (38). The receiving-part rib (34) protrudes from the short-side inner surface (15) and extends in the insertion direction. The elastic piece (35) is arranged between the receiving-part rib (34) and a long-side inner surface ((17) or (18)), and elastically deformable. The side elastic latch claw (38) is formed on the elastic piece (35).
