Title: Freezer refrigerator
Inventor: TAKEDA YASUHITO
IPC: F25D23/00
Filed: 1990-11-30
Abstract: PURPOSE:To prevent the temperature equilibrium between a freezing chamber and a refrigerating chamber from breaking down by mounting a damper to a duct which communicates a compressor installation space with said refrigerating chamber located above said compressor installation space wherein said damper is closed during he operation of a compressor and opened only under the condition where the operation is suspended and the temperature of open air is cold. CONSTITUTION:The air warmed by the heat generated from a compressor 24 during its operation rises in a compressor installation space 23 and remains within the installation space 23. When it is detected that the compressor 24 is suspended and the open air temperature is low by means of an open air thermostat 29, a damper 26 is opened, interlocking with the detection so that the warm air may be brought into a refrigerating chamber 20, thereby increasing the temperature in the refrigerating chamber 20. When the temperature in the refrigerating chamber 20 rises, the thermostat is turned ON and the compressor 24 starts its operation. The damper 26 is closed, interlocking with this where the in-flow of the warm air into the refrigerating chamber 21 is halted while the air in the compressor installation space 23 is warmed up by the heat generated from the compressor 24.

Patent JP-H07170166-A (JP)
Title: Semiconductor device
Inventor: OKAZAKI TAKAO
IPC: H01L27/06
Filed: 1993-12-13
Abstract: PURPOSE:To prevent through-current by selectively turning off a pull-down mOSFET or a pull-up MOSFET being the component of an input circuit in the low power consumption mode and forming an input logic circuit with a clocked inverter or the like. CONSTITUTION:When a communication LSI device is set to the low power consumption mode and an internal control signal PD is set to a high level, a MOSFETN3 is nonconductive and is not acted as a pull-down MOSFET. In this case, a clocked inverter CV1 is set to a nonconductive state. Furthermore, The FETN 3 is conductive through the reception of an inverted internal control signal PDB at a low level and acts as a pull-up MOSFET. Thus, the input signal level of the inverter V3 is fixed independently of the level of the input signal. Thus, while the level of the internal input signal ISin is fixed to a low level, the input current path via the N3 is interrupted to interrupt a through-current path by the inverter CV1.
