A method of the present invention, for producing an iodizing agent, includes the step of electrolyzing iodine molecules in a solution by using an acid as a supporting electrolyte. This realizes (i) a method of producing an iodine cation suitable for use as an iodizing agent that does not require a sophisticated separation operation after iodizing reaction is completed, and (ii) an electrolyte used in the method. Further, a method of the present invention, for producing an aromatic iodine compound, includes the step of causing an iodizing agent, and an aromatic compound whose nucleus has one or more substituent groups and two or more hydrogen atoms, to react with each other under the presence of a certain ether compound. This realizes such a method of producing an aromatic iodine compound that position selectivity in iodizing reaction of an aromatic compound is improved.

摘要:
A child seat is formed of a bottom squab on which buttocks of a child is seated, a seat back connected to the bottom squab for supporting a back of the child, and side walls disposed on side portions of the bottom squab and the seat back. An indicator for indicating an inclination angle of the child seat is arranged on a top of one of the side walls. In the child seat, the inclination angle of the seat can be easily checked through the indicator, thus facilitating the attachment of the child seat to a vehicle seat.
摘要:
A recording apparatus having a print head for printing characters on a medium and an ink tank for holding ink to be supplied to the print head. The ink tank includes an ink chamber having an ink holding member and an ink supplying port. A first meniscus forming member is located in the ink supplying port so as to be in communication with the ink holding member. The print head includes an ink introducing port for receiving ink from the ink tank and a second meniscus forming member located in the ink introducing port. When the ink tank is attached to the print head, the ink introducing port is coupled with the ink supplying port. An ink passing member is located in the portion where the ink introducing port is coupled with the ink supplying port. The ends of the ink passing member are in contact with the first meniscus forming member and the second meniscus forming member. The ink passing member is subject to only minor changes in volume upon contact with ink.
摘要:
An elastic jointing member 22 with an umbrella-like portion with an opening and a flat part is provided in a jointing portion between a recording head 21 and an ink tank 1. When the ink tank 1 is attached to the recording head 21, the umbrella-like portion of the elastic jointing member 22 is pressed against the ink tank and elastically deformed inward. As a result, an ink passage is formed which is airtightly sealed. In the process of pressing the umbrella-like portion against the ink tank, the umbrella-like portion comes in contact with the flat part, to thereby prevent air from staying in the ink passage. Protrusions or grooves may be provided between the umbrella-like portion and the flat part. With the protrusions or the groove, the umbrella-like portion is not glued to the flat part.
