摘要:
An absorption refrigerator which is capable of effectively using energy without a necessity of enlarging the size thereof, the absorption refrigerator having a structure that a cylindrical wall is provided for an inner wall portion raised because of a stepped portion of the bottom surface of a double-tube unit so that a refrigerant retainer for accumulating water allowed to downwards flow along the outer surface of a cold-water tube is formed. A refrigerant-circulating passage is connected to the bottom surface of the refrigerant retainer. Another end of the refrigerant-circulating passage is connected to a refrigerant supply passage. When a pump is operated, water in the refrigerant retainer is supplied to a water-receiving pan so as to again be sprayed to the outer surface of the cold-water tube.

The absorption chamber of an absorption-type air-conditioning apparatus is formed as a vertically oriented cylinder having an inner surface on which absorption liquid is dispensed for absorbing water vapor or coolant vapor. A guide structure is installed at the inner surface of the cylinder to lead the absorption liquid to the inner surface of the cylinder and to spread the absorption liquid over substantially all of the inner surface of the cylinder. The guide structure may be in the form of a mesh lath rolled into a cylindrical shape and installed against the inner surface of the cylinder or a helical coil installed against the inner surface of the cylinder and having a plurality of grooves formed on an outer surface of the coil to allow a portion of the absorption liquid flowing on an upward-facing surface of the coil to flow vertically downward to portions of the inner surface of the cylinder.

An absorption-type air-conditioning apparatus uses an absorption liquid that is a solution of a liquid coolant and an absorption medium. First and second regenerators are provided for heating the absorption liquid to release coolant vapor and concentrate the absorption liquid. Each of the regenerators includes a respective fin-tube-type heat exchanger in which the absorption liquid flows as it is being heated.

A hole plug has a head portion, a leg portion protruding from the head portion, and a flange portion protruding on an upper circumference of the leg portion. The leg portion includes an inner wall having an approximately cylindrical shape and connected to the head portion; and an outer wall extending along the inner wall with a gap among the inner wall from a folded portion provided in an end portion of the inner wall, and forming a bendable thin-walled portion. The thin-walled portion is elastically bent by an external force to be capable of transitioning from a first usage aspect in which the outer wall is locked in the hole with the thin-walled portion being in a non-bending state to a second usage aspect in which a force larger than the first usage aspect is provided to pressure contact relative to the hole.

An ultrasonic sensor includes a substantially cylindrical case including a bottom portion and a side wall portion and a plurality of members disposed within the case. A reinforcement having a substantially ring shape is fitted on a thick section in the case at a location that is not in contact with an inner surface of a thin section of the side wall portion. A piezoelectric element is attached to an inner bottom surface of the case. An elastic member is fitted on the reinforcement so as to cover a substantially ring-shaped opening region of the reinforcement. A gap between the elastic member and an inner circumferential surface of the case is filled with a first filler. The terminal holding member is placed on the elastic member. A surrounding region of the terminal holding member is filled with a second filler.

Diphenyl sulfone crosslinking type compounds of general formula (1) and a recording material containing at least one of them. This recording material is excellent in the storage stability of colored images. ##STR1##
摘要:
A diphenylsulfone derivative of the formula (I) ##STR1## which is highly safe and used for imparting storage stability to a colored image of thermal or heat sensitive recording material, wherein R.sup.1 represents lower alkenyl or aralkyl optionally substituted with halogen or lower alkyl, and R.sup.2 represents hydrogen or methyl, provided that R.sup.2 represents methyl when R.sup.1 represents unsubstituted benzyl.
