  • Patent number: 9688309
    Abstract: In a suspension tower plate, in a plate body that is made of a sheet metal and is a part of an upper wall portion of a suspension tower, three suspension fixing portions are disposed. Three suspension fixing portions fix to an upper end part of a suspension. Further, in the plate body, a bend portion is disposed on an outer periphery side of the three suspension fixing portions. In the suspension fixing portion and the bend portion like this, strain is likely to be generated by an upward load that is input from the suspension. However, in the suspension tower plate, the suspension fixing portion and the bend portion thick portions are disposed. Thick portions are thicker than the plate body.

  • Publication number: 20170132505
    Abstract: An RFID tag substrate contains a paper substrate having an eluted chloride ion amount per unit mass (1 g) of 0.100 mg or less, having formed on a surface thereof a conduction circuit. A specimen of the paper substrate is broken into small pieces each of 100 mm2 or less. The small pieces are immersed in a polypropylene vessel having 50 mL of water with an electric conductivity of 0.2 mS/m or less. After standing, the water is filtered with a membrane filter to recover a filtrate and the filtrate is analyzed by an ion chromatography method to obtain a chloride ion (Cl?) concentration in the filtrate, from which a total chloride ion amount eluted into 50 mL of the water is obtained, and is divided by the mass (g) of the specimen to provide a value, which is designated as the eluted chloride ion amount per unit mass.
