Abstract: The object of the invention is to provide an ammonia/CO2 refrigeration system in which the ammonia cycle and CO2 brine cycle can be combined without problems even when refrigeration load such as refrigerating showcase, etc. is located at any place in accordance with circumstances of customer's convenience. The system comprises apparatuses working on an ammonia refrigerating cycle, a brine cooler for cooling and condensing CO2 by utilizing the latent heat of vaporization of the ammonia, and a liquid pump provided in a supply line for supplying the cooled and liquefied CO2 to a refrigeration load side cooler, wherein said liquid pump is a variable-discharge pump for allowing CO2 to be circulated forcibly, and the forced circulation flow is determined so that CO2 is recovered from the outlet of the cooler of the refrigeration load side in a liquid or liquid/gas mixed state.

Abstract: A continuous transfer type freezer for cooling or freezing articles such as foodstuffs transferred on a conveyor belt by spraying chilled air from slit nozzles on the articles is provided in which chilled air jets rectified to have long spray travel is produced, thin stream layer of chilled air is formed on the surface of the article to achieve increased heat transfer, and exhaust passages of the chilled air are formed such that they do not affect the cooling function. A plurality of slit nozzles 5a, 6a are apposed above and under the conveyor belt along the belt transfer direction, each of the nozzles 5a, 6a is shaped such that it has an angled and succeeding parallel entrance way so that the chilled air is rectified in the entrance ways and spout from the nozzle opening at large velocity, and exhaust passages 12 are formed between each of the slit nozzles such that the chilled air spouted from the nozzles flows toward both lateral end sides of the conveyor belt 2.

Abstract: A magnetic domain controlling film for controlling the magnetic domain of a magnetoresistive film is formed by the patterning technique on a lower insulating film formed on a lower shield film. The magnetoresistive film is formed on the magnetic domain controlling film for converting a magnetic signal from a magnetic recording medium into an electrical signal using the magnetoresistive effect. A resist pattern is formed by the lift-off method on the magnetoresistive film in such a fashion as to leave a region of the magnetoresistive film corresponding to the tracks of the magnetic recording medium. A magnetoresistive element is formed by ion milling leaving only the portion of the magnetoresistive film corresponding to the tracks.
