Outdoor unit for air conditioner

A heat exchanger includes: a heat exchange element including flat tubes spaced from each other; and a first header in which one end portion of each of the flat tubes is inserted. The first header includes: a first main header portion in which some of the flat tubes are inserted; a first sub-header portion in which others of the flat tubes are inserted such that the number of the flat tubes inserted in the first sub-header portion is smaller than that of the flat tubes inserted in the first main header portion; and a partition plate provided between the first main header portion and the first sub-header portion, and joined to the first main header portion and the first sub-header portion. The partition plate has a surface area that is larger than a sectional area of the first main header portion and a sectional area of the first sub-header portion.

The present invention provides an ink jet recording sheet excellent in ink absorption properties, surface gloss, transparency and color of recorded images. The ink jet recording sheet has a gloss like photographic papers and has a high transparency, and can be used as OHP films. In this ink jet recording sheet, an ink receiving layer containing a pseudo-boehmite alumina hydrate and a binder is provided on a support, the ratio of a pore volume of the pores having a radius of 13 nm or more and less than 50 nm to a pore volume of the pores having a radius of 3 nm or more and less than 13 nm is 0.3-0.9 or the pore volume of the pores having a radius of 13 nm or more and less than 50 nm is 0.1-0.5 ml/g. Furthermore, the ink receiving layer has a surface pH of 4.0-5.4.

Ink jet recording material

Disclosed is a reversible heat-sensitive recording material comprising a substrate and a recording layer formed thereon, said recording layer comprising a colorless or light-colored, electron-donating dye precursor and a specific electron-accepting compound capable of causing a reversible color tone change of the dye precursor on heating.

Reversible heat-sensitive recording material

As a reversible heat-sensitive recording material which contains a normally colorless or palely colored electron donating dye precursor and an electron accepting compound capable of causing said dye precursor to change reversibly in color density due to the difference in cooling rate after heating, one in which images can be formed and erased with good contrast and images high in time stability can be maintained under environment of everyday life can be obtained by using a phenolic compound having at least one aliphatic hydrocarbon group of 6 or more carbon atoms as the said electron donating compound.

A pedometer for exercise such as walking and jogging, comprising the fact that an appropriate intensity of exercise is set by setting reference signals, which the user of the pedometer is permitted to hear with a sound producer or an earphone, thereby making it possible to render the user conscious of the exercise at the appropriate intensity and to count or measure and then display the number of steps of the exercise, the period of time thereof, and the continuation period of time thereof as associated with the set reference signals.

Pedometer for walking, jogging, etc.

There is disclosed a thermosensitive recording material comprising an ordinarily colorless or slightly colored dye precursor, an electron receptive compound (developer) coloring said dye precursor by reacting when heated, and a compound of following general formula (I) ##STR1## wherein R.sub.1 and R.sub.2 each represents hydrogen atom, alkyl, alkenyl or aryl group, and R.sub.1 and R.sub.2 may be different from each other; may also be linked together to form cycloalkyl, cycloether, and the like; and R.sub.3 and R.sub.4 each represents hydrogen atom, alkyl, alkenyl, alkoxy or aryl group and halogen atom, and R.sub.3 and R.sub.4 may be different from each other.
