IPC: F24H1/00
Filed: 2009-03-03
Abstract: <P>PROBLEM TO BE SOLVED: To provide a heat pump water heater capable of suppressing the accumulation of a scale in stopping an operation of a heat pump operation.  <P>SOLUTION: The heat pump water heater includes a refrigerating cycle having a compressor, a water-refrigerant heat exchanger exchanging heat between a refrigerant flowing in the refrigerating cycle and the water flowing inside, a hot water/water supply circuit for storing the water boiled by the heat exchange by the water-refrigerant heat exchanger in a tank, and a control means performing a boiling operation by operating the compressor of the refrigerating cycle and a pump disposed in the hot water/water supply circuit, distributing the water in the tank to the water-refrigerant heat exchanger by the pump, boiling the water by the heat exchange with the refrigerant in the water-refrigerant heat exchanger, and returning the water to the tank. The control means performs a scale generation preventing operation for stopping the compressor and continuing the motion of the pump when the boiling operation is stopped. In the scale generation preventing operation, a temperature difference between a temperature of stored hot water at a hot water storage port at an upper section of the tank and a water inlet temperature at a water inlet side of the water-refrigerant heat exchanger is determined, and the motion of the pump is stopped when the temperature difference reaches a prescribed value or smaller.  <P>COPYRIGHT: (C)2010,JPO&INPIT

IPC: G03B17/14
Filed: 2009-03-04
Abstract: <P>PROBLEM TO BE SOLVED: To compare various types of version information of each unit with one another in initialization processing for turning on power supply, determine compatibility, suspend the upgrading operation if this camera system does not operate properly, and report that fact in order to facilitate version management when performing version updating processings.  <P>SOLUTION: The camera system waits to receive the version information from a lens unit when power is turned on (S1), compares the version number of a body unit with the version number of the lens unit after receiving the version information (S2), transmits the version information on a body unit side to the lens unit after the comparison (S3), and determines whether operation is started or stopped based on the result of comparison (S4). If the version has compatibility (Yes at S4), the processings for version management come to an end, proceeding to usual initialization processing (S8). If the version has no compatibility (No at S4), this system displays a warning picture (S5), waiting for "Yes" operation to confirm the displayed warning screen (S6). When this system performs the "Yes" operation (Yes at S6), operation of this system proceeds to the processing for turning off power supply automatically (S7) and comes to an end because this camera system does not operate as it is.  <P>COPYRIGHT: (C)2010,JPO&INPIT
