Abstract: A temperature detection circuit of a semiconductor memory apparatus includes a fixed period oscillator, a temperature variable signal generating unit and a counting unit. The oscillator is configured to generate a fixed period oscillator signal when an enable signal is enabled. The temperature variable signal generating unit is configured to generate a temperature variable signal whose enable interval varies based on temperature variations, when the enable signal is enabled. The counting unit is configured to count the oscillator signal during the enable interval of the temperature variable signal to generate a temperature information signal.

Abstract: A method of measuring the height of a foot arch precisely and easily using two essential heights of the foot arch is disclosed. In the method, a foot cast is primarily cast by pouring plaster into a foot mold. Thereafter, a first intersecting point and a second intersecting point are determined. The first intersecting point is determined by making a first line and a third line intersect. The second intersecting point is determined by making a second line and the third line intersect. The first line is a straight line extending from the center of the second toe to the center of the heel end. The second line is a straight line extending from the center of the big toe to a point spaced apart inwardly from the center of the heel end by ⅛ of the total distance of the heel end. The third line is a center line of the transverse arch of the foot. Finally, a first height and a second height are measured while the foot pattern is set in an upright position.

Abstract: A travelling toothbrush is combined with a razor head disclosed. In the travelling toothbrush with a handle and brush part, a first longitudinal recess is formed on one side of the handle and receives a toothpaste tube therein. A second longitudinal recess is formed on the other side of the handle and receives a disposable razor head therein. The second recess includes a dovetail for holding the razor head therein. A razor head mounting protrusion is provided on the rear portion of the other side of the handle and mounts the razor head to the handle when using the toothbrush as a razor. A handle case is detachably fitted over the handle, while a cap is detachably fitted over the brush part to protect the brush part. The cap has a clip and forms a configuration of a conventional fountain pen in cooperation with the handle case.

Abstract: This specification provides a polymeric material useful for manufacturing contact lenses having improved oxygen permeability. The contact lenses prepared from the polymeric material of the invention show improved hydrophilicity and enhanced oxygen permeability as compared with that made of the conventional fluoroalkyl-containing polymeric materials.
