Abstract: A power converter device includes first through third semiconductor modules provided for phases of a three-phase inverter circuit, and incorporating upper and lower arms series circuit, and a flow path forming cabinet in a rectangular prism shape having an electric equipment containing space and a coolant flow path formed to surround the electric equipment containing space, the coolant flow path includes a first flow path provided along a first side face of the flow path forming cabinet, a second flow path provided along a second side face contiguous to one side of the first side face and connected to one end of the first flow path, and a third flow path provided along a third side face contiguous to other side of the first side face and connected to other end of the first flow path.

Abstract: A power inverter includes a plurality of power modules; a first casing housing the power modules and a cooling path in which a coolant flows is formed; a plurality of AC busbars connected to AC terminals of the power modules; a holding member, in which a positioning pin protruding to an upper side in a direction opposite to the first casing is formed, that maintains the AC busbars and is fixed to the first casing; a current sensor module including a plurality of current sensors detecting the AC currents of the AC busbars; a frame body for maintaining the current sensors, and a lead terminal protruding from the frame body to the upper side; and a driver circuit board, in which a through-hole used for the lead terminal and a board positioning through-hole are formed, arranged on the upper side of the frame body arranged on the holding member.

Abstract: Disclosed is a toner binder which has high storage stability and can achieve both of good low-temperature fixability and good hot offset resistance (a broadened fixing temperature range). Specifically disclosed is a toner binder comprising, as constituting units, a carboxylic acid component (x) and a polyol component (y), wherein the component (x) comprises two or more kinds of dicarboxylic acids (X1), selected from among aromatic dicarboxylic acids and ester-forming derivatives of the same, in a total amount of 80 mol % or more and a trivalent or higher polycarboxylic acid (x2); the component (y) comprises a polyester resin (P) which is constituted by a polyester resin (A) comprising 80 mol % or more of an aliphatic diol (y1) having 2 to 10 carbon atoms optionally together with a linear polyester resin (B); and the storage modulus at 150° C. [G?150] of resin (A) is 20000 dyn/cm2 or more and the ratio of [G?150] to the storage modulus as 180° C. [G?180] thereof, i.e., [G?150]/[G?180], is 15 of less.

Abstract: A medical treatment device includes a first medical treatment implement such as a hollow needle, and a second medical treatment implement such as a bag. A first tubular member, such as a needle hub, is connected to the first implement. A second tubular member, such as a flexible tube, having first and second end portions is connected to the second implement at the second end portion. The first end portion of the second tubular member is joined and blocked with one end portion of the first tubular member in a superposed and liquid-tight state.

Abstract: A cannula device has a hollow needle, and a hub which supports the hollow needle at the proximal end portion thereof and which is made of a hard plastic. A protector comprises a hollow body whose distal end is closed and whose proximal end is open and which is made of a hard plastic. The protector is detachably mounted on the hub such that the hollow body houses the hollow needle therein and the proximal end of the hollow body covers the distal end portion of the hub. A resilient layer is formed between the inner circumferential surface of the proximal end portion of the hollow body and the outer circumferential surface of the distal end portion of the hub.

Abstract: Medical instruments unsuited for gas sterilization, such as blood bag, transfusion bag, blood circuit or the like, are sterilized together with tubes connected thereto by autoclave sterilization. The medical instrument subjected to autoclave sterilization is made of a material such as a resin of vinylchloride group, ethylene-acetate vinyl resin or the like which exhibits a high tendency for blocking. According to the invention, the tubes for medical instruments which are destined for autoclave sterilization are provided on their peripheral surfaces with longitudinal ribs of specific dimensions to diminish the tendency of blocking during the autoclave sterilization and to facilitate the separation of tubes even if any blocking has taken place.
