    摘要: The present invention relates to a surface contour measuring tracer permitting a probe element to move in the directions of X-, Y- and Z-axes. A support structure includes a base supporting thereon an X-slider and a Y-slider which are movable in the directions of X- and Y-axes, respectively. A Z-slider is supported on the X-slider so to be movable in the direction of a Z-axis. Supported on the Z-slider is a probe element, the movements of which in the directions of X-, Y- and Z-axes are permitted by the movements of the X-, Y- and Z-sliders. The X- and Y-sliders are normally held at neutral positions by a wire spring extending in the direction of the Z-axis, and the Z-slider is permitted to move in the direction of the Z-axis against the action of a coil spring and normally held at a neutral position.

    摘要: The present invention provides a brine composition for a frozen food which does not raise the freezing temperature even if the ethanol concentration is low, and is therefore able to suppress tissue breakdown caused by the growth of water ice crystals in the tissues (cells) of foods, and a method for producing a frozen food. The brine composition for a frozen food contains 30 to 70% by weight of ethyl alcohol, 0.5 to 10.0% by weight of erythritol, and water. It is preferable that the concentration of the ethyl alcohol is 35 to 60% by weight, the concentration of the erythritol is 0.8 to 5.0% by weight, and the rest is water.
