Abstract: Provided are an emulsifier exhibiting a high preservation stability and having an excellent emulsifying capability in a wide range of emulsification compositions; and an emulsion composition containing such emulsifier. The emulsifier is comprised of a diblock copolymer whose main chain is comprised of a silicone graft copolymer block [I] and a polar copolymer block [II], wherein one end structure of the main chain is represented by a formula [III], and the other end structure of the main chain is represented by a formula [IV], the formulae [I] to [IV] being expressed as wherein R1 represents a hydrogen atom or methyl group; A represents an organopolysiloxane-containing group; n1 satisfies 1?n1?50; B represents a polar group-containing monovalent hydrocarbon group, an amino group or a hydroxyl group; n2 satisfies 1?n2?50; R6 represents an alkyl group; R7 independently represents a hydrogen atom or an alkyl group; X is A or B.

Abstract: Provided are a surface treatment agent for powder capable of being used to produce a dispersion superior in dispersibility, fluidity and temporal stability; and a dispersion containing a powder treated with such surface treatment agent for powder. The agent is a diblock copolymer whose main chain is comprised of a silicone graft copolymer block represented by a formula [I] and a polar copolymer block represented by a formula [II], wherein one end structure of the main chain is represented by a formula [III], and the other end structure of the main chain is represented by a formula [IV], the formulae [I] to [IV] being expressed as wherein A represents an organopolysiloxane-containing group; B represents a polar group-containing monovalent hydrocarbon group having 1 to 20 carbon atoms, an amino group or a hydroxyl group.

Abstract: A first cable conductor portion is placed on a first connector terminal. The first cable conductor portion is accommodated in a pressing recessed portion formed in an applying member. Ultrasonic vibration is applied to the first cable conductor portion and the first connector terminal and the first cable conductor portion and the first connector terminal are pressed, and thereby to be welded to each other.

Abstract: A connector for a flat cable is equipped with a resin-made holder and a resin-made cover that is mounted on the holder. The holder has two metallic bus bars for making connection of a flat cable with two electric wires. The respective bus bars are insert molded in the holder and have flat plate-like portions of connection that are arranged in the form of a flat plane by being spaced away from each other. The outer periphery of each portion of connection is exposed from the holder. The flat cable has two conductors. The respective conductors have exposed conductor portions that are extended in array. Each electric wire has a core wire portion. On the respective connection portions there are superposed their corresponding exposed conductor portions and core wire portions, respectively. The respective core wire portions are connected to their corresponding connection portions by ultrasonic welding.
