Abstract: A tape measure is provided which has less rotational wearing and trouble, increased reliability of cooperative rotation, and an easier assembling and disassembling structure. The tape measure is characterized in that a unitized gear mechanism can be taken out from outside, and a sub-rotary disc axis member and a take-up drive can be rotated together.

Abstract: An oxidizing composition comprises an aqueous solution of peracetic acid, hydrogen peroxide and acetic acid and a fragrant component uniformly solubilized in the peracetic acid-containing aqueous solution by aid of a surfactant component, the fragrant component comprising at least one fragrance material which is chemically stable in the presence of peroxide compounds and effectively masks the irritating odor of peracetic acid and acetic acid.

Abstract: An interior panel according to the present invention comprises a plurality of support units fixedly arranged on a floor slab, a panel member supported by the support units so as to be located over the slab surface at a predetermined distance therefrom, and a cable separator supported by the support units and dividing the space between the panel member and the slab surface into upper and lower space sections. The cable separator is in the form of a plate with a stepped surface portion at the peripheral edge portion thereof, and can be supported on the support units either in a first position in which the stepped portion faces upward or in a second position in which the stepped portion faces downward. Cables and electric devices in a signal transmission system are arranged in the upper space section defined by the cable separator, and power supply-system cables and devices in the lower space section.

Abstract: A cooling apparatus for a housing which is provided with an opening at the upper part thereof, comprises a casing located on the upper part of the housing and including a bottom plate to close the opening and a chamber, a partition wall provided in the casing to divide the chamber into a first chamber section and a second chamber section, heat exchanger including at least one heat pipe provided in the casing through the partition wall with coolant therein for exchanging heat in the first chamber section with heat in the second chamber section. The heat pipe has one end portion in the first chamber section and the other end portion in the second chamber section, and inclines with the one end portion located lower than the other end portion.
