IPC: F25D21/00
Filed: 1998-12-23
Abstract: PURPOSE: A method is provided to drive a defrosting heater based on the ordinary driving time instead of periodically driving the heater for an equally set time when a temperature sensor is out of order. CONSTITUTION: A defrosting system checks if a temperature sensor is out of order. If not, the system drives a defrosting heater according to the temperature sensor. The system stores the driving time of the defrosting heater by dividing into time sections. Then the system checks if the sensed value of the temperature sensor is more than the set value. When the temperature sensor is out of order, the system outputs an average time of the stored driving time. According to the time, the system drives the defrosting heater and then drives an evaporator.

Title: Rotary compressor
Inventor: YUN SANG PIL
IPC: F04C2/356
Filed: 1998-12-24
Abstract: PURPOSE: A rotary compressor is provided to reduce its volume by making a cylinder rotated by extending the lower part of the cylinder toward a stator. CONSTITUTION: By turning a cylinder(130) 90 angular degrees counterclockwise, a compressing chamber(131) is divided into a first chamber(131a) and a second chamber(131b) by a vane(135) and a roller(150). Coolant gas is sucked into the first chamber via a suction hole(151) of the roller and then compressed in the second chamber. If the cylinder rotates counterclockwise continuously, the coolant gas is sucked continuously to the first chamber ad the coolant gas in the second chamber is compressed more. When the pressure of the second chamber overcomes the force of a valve installed in an outlet port(137), the coolant gas is discharged via the outlet port and returned by the rotation of the cylinder. The suction and discharge of the coolant gas is repeated continuously by the divided compressing chamber.

Abstract: PURPOSE: A both side printing device of an electro-photographic processor is provided to minimize a whole size of a product by defining a paper turning up path by using a manual feed tray without providing any additional paper turning up elements occupying an additional space, thereby improving assembling workability and reducing manufacturing cost. CONSTITUTION: A both side printing device of an electro-photographic processor includes a guide for opening and closing a paper turning up path(21) mounted in a paper discharging die to be opened in a both side printing mode, a paper turning up and conveying path formed from the guide to a register roller(4), paper turning up and discharging rollers(22,23) mounted in the paper turning up and conveying path to discharge a paper toward a manual feeding tray(31), and position detecting sensors(24,25) mounted at an inlet part of the paper turning up and discharging roller for sensing a rear end of a paper to turn up.
