摘要:
The present invention relates to a method for controlling the operation of a compressor for preventing noise that occurs in case of the shortage of refrigerant flow caused by less discharge capacity of the compressor of an air conditioner for a vehicle. The compressor includes a cylinder bore for compressing a refrigerant, a piston inserted into the cylinder bore, a swash plate having a controllable slope with respect to a drive shaft, and a control valve for controlling the slope of the swash plate. The discharge capacity of the compressor is increased if it is determined that vehicle speed and accelerating rate satisfy predetermined conditions. If a low flow rate state of refrigerant of the compressor is predicted, the ECV duty is increased to prevent the compressor from entering the low flow rate state, thereby improving the workability of the compressor and solving the noise problem.

摘要:
A vehicle air conditioner is controlled to a target control value that controls a swash-plate control value of a swash-plate variable capacity compressor. The variable control is based on temperature deviation between target evaporator temperature and actual evaporator temperature, to control compressor discharge capacity. A target evaporator temperature is set. Deviation between the target evaporator temperature and actual evaporator temperature is calculated. Control coefficients are variably set according to the magnitude of the temperature deviation. A target control value of a pressure control valve of the swash-plate variable capacity compressor is calculated using the control coefficients. The pressure control valve is controlled by the target control value.

摘要:
In a method of manufacturing a semiconductor device, a preliminary insulating layer is formed on a substrate. A photoresist pattern is formed on the preliminary insulating layer. A central portion of the preliminary insulating layer is partially etched using the photoresist pattern as an etch mask to form a preliminary insulating layer pattern including a central portion and a peripheral portion on the substrate. The peripheral portion of the photoresist pattern is higher than that of the central portion of the preliminary insulating layer pattern. The preliminary insulating layer pattern is polished to form a planarized insulating layer on the substrate.

A phase changeable memory device is manufactured by forming at least one insulating layer on a substrate. A preliminary first electrode is formed on the insulating layer. The preliminary first electrode is partially etched to form a first electrode electrically connected to the substrate. After the preliminary first electrode is formed, both sidewalls of the preliminary first electrode are partially etched isotropically to form a first electrode having a uniform width and height. A phase changeable material layer pattern and a second electrode are subsequently formed on the first electrode. Related devices also are described.
