Abstract: An electrolyte solution containing a compound represented by the following formula (1).

Abstract: A master station (111) and a slave station (121) each communicate an individually set, fixed number of communication frames in a cyclic period. The communication frame contains, as communication information, a sequence number and a period number. The master base station (113) and the slave base station (123) determine, upon communication of each communication frame in a wireless manner, if there is a missing communication frame on a basis of the communication information of a this-time communication frame and the communication information of a last-time communication frame. When there is a missing communication frame, a history management server (300) records communication history information of the last-time communication frame and of the this-time communication frame, as preceding/succeeding history information.

Abstract: Provided is an aqueous coating composition capable of forming a fluororesin coating film layer with excellent electrical properties and surface physical properties, and good adhesive properties. A coating composition containing 2 or more kinds of fluororesins, wherein at least 1 kind of the fluororesin, a fluororesin (I), has a number of functional groups of 30 to 1,000 per 106 main-chain carbon atoms, and the coating composition further contains an inorganic filler, a surfactant, a liquid medium, and a non-fluororesin.

Abstract: A sleeve in the shift control device includes a sleeve main body and a first convex section. The first convex section is annular in shape and protruded radially outward from the outer circumferential surface of the sleeve main body. The shift fork includes a fork main body, a second convex section, a ring, and a joining member. The fork main body is annular in shape and disposed radially outside the sleeve main body. The second convex section is annular in shape, axially disposed side by side with the first convex section, and protruded radially inward from the inner circumferential surface of the fork main body. The first convex section is axially sandwiched between the ring and the second convex section. The joining member is disposed in a space that is formed by a first groove formed in the ring and a second groove formed in the fork main body.

Abstract: 3,4-Dicarboalkoxybiphenyl-3?,4?-dicarboxylic acid represented by the general formula (1): in which R11 and R12 each represents an alkyl group having 1 to 4 carbon atoms, and n represents the number of waters of hydration that is 0 or 1, and the corresponding anhydride.

Abstract: A grip for a backpack-type air blowing machine which performs a work by using air discharged from a distal end of an air blowing pipe that is coupled to a blower body driven by a power source while the air blowing pipe is manipulated by an operator with the power source and the blower body being carried on a back of the operator. The grip comprises a base section that constitutes an attachment section to the air blowing pipe, a vertical grip section that is provided with a proximal end portion provided continuously to the base section, and that extends in a direction away from the air blowing pipe, and a lateral grip section that extends backward along the air blowing pipe from a free end of the vertical grip section. The lateral grip section is located adjacent to a back of a hand of the operator holding the air blowing pipe.

Abstract: The air-blow working machine comprises a fan provided in a fan casing and a drive unit to drive the fan, and discharges an airflow generated by the rotating fan. The fan casing has an inner wall disposed between the fan and the drive unit. A smooth surface is formed on the face of the inner wall on the side of the fan. A first concavo-convex portion is formed on the face of the inner wall on the side of the drive unit. Thereby, a noise is reduced without an influence upon performance for blowing air.

Abstract: 3,4-Dicarboalkoxybiphenyl-3?,4?-dicarboxylic acid represented by the general formula (1): in which R11 and R12 each represents an alkyl group having 1 to 4 carbon atoms, and n represents the number of waters of hydration that is 0 or 1, and the corresponding anhydride.

Abstract: The present invention relates to the 3,4-Dicarboalkoxybiphenyl-3?,4?-dicarboxylic acid (including the corresponding acid anhydride) represented by the general formula (1): wherein R11 and R12 each represents an alkyl group having 1 to 4 carbon atoms, and n represents the number of waters of hydration that is 0 or 1.

Abstract: Disclosed is a method for producing a biphenyltetracarboxylic acid ester by oxidative coupling a phthalic acid ester by using a catalyst comprising at least a palladium salt, a copper salt and a ?-dicarbonyl compound in the presence of a molecular oxygen, wherein the ?-dicarbonyl compound is supplied into a reaction mixture liquid intermittently at an interval of less than 30 minutes, or continuously. This method allows, in particular, the selective and economical production of an asymmetric biphenyltetracarboxylic acid tetraester such as 2,3,3?,4?-biphenyltetracarboxylic acid tetraester.

Abstract: A backpack strap includes a strap main body, an upper end of which is connected to a backpack frame, a pad attached to the strap main body on a user side, and a contact state holding unit holding an upper end of the pad in contact with the backpack frame. Upper portions of the strap main body and pad are spaced apart from each other by a specified distance. The upper end of the pad has a shape and a strength that is, when contacting the backpack frame, able to prevent the backpack strap from falling sideways. Due to a tensile force of the upper portion of the strap main body and a stiffness of the upper portion of the pad, the upper portion of the pad is held in a projecting state with the upper end of the pad acting as a support point.
