Abstract: A frozen dessert dispenser includes a heat-insulating box, a cooling unit for cooling an atmosphere in the heat-insulating box, a dispensing cylinder including a piston ascended and descended by an operating fluid and a pack accommodating chamber in which a frozen dessert pack is accommodated, a pump supplying and discharging the operating fluid to and from a pressure chamber defined in the dispensing cylinder, and a usually closed operating fluid introducing port disposed in the cylinder. The operating fluid introducing port is opened so that the operating fluid is introduced into the pressure chamber, when the piston reaches a bottom dead point.

Abstract: A frozen dessert dispenser for dispensing ice cream etc. includes a heat-insulating box having a side formed with an opening closed and opened by a heat-insulating door, a dispensing cylinder including a piston and a pack accommodating chamber defined between the piston and a lid closing an upper opening of the cylinder. A frozen dessert pack is accommodated into the pack accommodating chamber when the lid is opened. The dispensing cylinder is mounted on a bracket further mounted on a backside of the door. The bracket positions the dispensing cylinder in the heat-insulating box and is rotated relative to the door so that the dispensing cylinder is inclined from a standing position where the dispensing cylinder stands along the door to a inclined position where an upper end of the dispensing cylinder is spaced away from the door.

Abstract: In a low temperature storage house having a temperature sensor for detecting an internal temperature of the storage house, a cooling apparatus for cooling the interior of the storage house, cooling control means for repetitively controlling operation and stop of the cooling apparatus based on the internal temperature detected by the temperature sensor and for maintaining the internal temperature in a value between predetermined upper and lower limit temperatures, and display means for indicating the internal temperature detected by the temperature sensor in the form of letters, an abnormal display apparatus for the low temperature storage house comprises abnormal detection means for detecting the plural kinds of abnormalities respectively occurring in the low temperature storage house; abnormal data forming means for forming abnormal data indicative of each of the abnormal kinds in accordance with the kinds of abnormalities detected by the abnormal detection means; and display control means for applying each
