20090001866 | Refrigeration unit - In a refrigeration unit including a variable performance compressor driven by an inverter motor, a sensor is configured to detect a physical amount corresponding to a refrigerant pressure on the high-pressure side of a refrigerant circuit. A measured value of the physical amount is compared with a first reference value corresponding to a first predetermined pressure of the refrigerant and a second reference value corresponding to a second predetermined pressure lower than the first predetermined pressure. A protective operation can start if the comparison result indicates that an actual refrigerant pressure is higher than the first predetermined pressure. The performance of the compressor can be gradually lowered if the comparison result indicates that an actual refrigerant pressure is between the first predetermined pressure and the second predetermined pressure. | 01-01-2009 |
20090007575 | Cooling apparatus - A cooling apparatus such as a refrigerator includes a refrigeration cycle including a compressor driven by an electric motor, a condenser, a throttle valve and an evaporator, a first physical amount detector capable of detecting a physical quantity representing a temperature of an object to be cooled by the cooling operation of the evaporator, a temperature control device capable of controlling a rotating speed of the motor based on the physical quantity detected by the first physical quantity detector so that the object is cooled approximately to a target temperature, a second physical quantity detector capable of detecting a physical quantity corresponding to a performance margin of the refrigeration cycle, and a rotating speed limiter capable of limiting the rotating speed of the motor to or below a predetermined speed based on a physical quantity detected by the second physical quantity detector. | 01-08-2009 |

20090105884 | Cooling Storage Cabinet and Method of Operating the Same - A cooling device is provided with an inverter compressor. Set speeds of the inverter compressor can be switched to six stages from a first speed to a sixth speed. The relationship between each of the set speeds of the rotational speed is set so that the stages adjacent to each other have gradually larger differences in rotational speed as the rotational speed becomes higher. With this, independently from the level of the rotational speed, a degree of increase in cooling performance between each of the stages can be equalized. In a case of performing a control to increase or decrease the rotational speed of the inverter compressor stage by stage depending whether an actual temperature drop rate is larger or smaller than a target temperature drop rate, the change amounts in cooling performance that can be substantially equalized, and too high or too low cooling performance does not result, i.e. fluctuation in cooling performance can be minimized. Thus, control to drop the internal temperature in accordance with a predetermined cooling characteristic can be stably performed. | 04-23-2009 |

20130168365 | MASH SEAM WELDING METHOD AND APPARATUS - Mash seam welding is performed to weld metal plates with thicknesses of 2 mm or more to stabilize the strength of a joint portion, reduce uneven parts of the joint portion, and ensure high strength and reliability of the joint portion. First, two metal plates, clamped with first and second clamping devices, are placed to overlap each other at their end portions. The overlapping portions (L) of the metal plates are pressed together with a pair of upper and lower electrode wheels while welding currents flow to continuously weld the overlapping portions (L) and join the metal plates. The pressing forces applied to the electrode wheels are controlled so that upper and lower welding forces acting upon the overlapping portions are equal to each other during the time when the overlapping portions are continuously welded. | 07-04-2013 |
