Title: Refrigerating storage cabinet and control method for compressor thereof
Inventor: KONDOU NAOSHI
IPC: F25D29/00
Filed: 2007-02-26
Abstract: A deviation calculation means (42) calculates the deviation of the temperature in a storage detected by a temperature sensor (35) from a target temperature given from a target temperature setting means (41) every predetermined time, a deviation integration means (46) integrates the deviation, and the number of revolutions of an inverter motor for driving a compressor is increased on conditions that the integrated value exceeds a predetermined reference value. Even if a door is opened temporarily and the temperature in the storage is raised temporarily by outer air flowing into the storage chamber, the integrated value of temperature deviation is not varied suddenly and control is stabilized because the number of revolutions of the compressor does not react too sensitively to quickly increase. The cooling storage can be prevented from responding to sudden change of temperature in the refrigerator with unnecessary sensitivity and it can be operated with higher efficiency.

IPC: G06F11/10
Filed: 2008-04-10
Abstract: Memory space of a digital device may be configured for both instructions/data (op-code) and ECC or parity when required, otherwise the entire memory space may be configured for just the program instructions/data. A standard word width memory may be configured for ECC or non-ECC functionality, or parity or non-parity functionality, based upon a desired application. The last portion of the memory may be allocated for ECC or parity data rather then application code when an ECC or parity implementation is required. When an ECC or parity implementation is not required, the entire memory may be used for the application code. This allows a digital device and memory to be used in applications having different robustness (e.g., application code integrity) requirements without have to fabricate different digital devices.
