Abstract: During heat applying operation, both an air-source heat exchanger that exchanges heat with the atmosphere as a heat source and an earth-source heat exchanger that uses geothermal heat as a heat source serve as evaporators to collect heat from the atmosphere and the geothermal heat. During defrosting operation, while a four-way valve is switched to cause the air-source heat exchanger to serve as a radiator, and the earth-source heat exchanger to serve as an evaporator to collect the geothermal heat, and the collected geothermal heat is collected in the main circuit via the sub-circuit.

Abstract: An object is to enable the dealer or user of an air conditioning apparatus to recognize that the heat dissipation amount of a heat exchange device is less than the heat dissipation amount expected of the air conditioning apparatus. A control device detects a hot water outflow temperature being a temperature of a fluid heated by a heat pump device, and a return temperature being a temperature of the fluid before being heated by the heat pump device, and checks whether or not a temperature difference between the detected hot water outflow temperature and the detected return temperature is smaller than a predetermined first value. If the control device judges that the temperature difference is smaller than the first value, it displays insufficiency of the heat dissipation amount of a heat exchange device, on a display of a remote controller.

Abstract: An outdoor unit includes a bypass circuit that makes a part of refrigerant that is discharged from a compressor be bypassed to a connecting part at the time of defrosting operation. A control device of the outdoor unit performs control of opening an electromagnetic valve in the bypass circuit based on an water temperature TW (in) in an water inlet and an water temperature TW (out) in an water outlet of an water heat exchanger at the time of the defrosting operation. Further, a control device controls a valve travel of the valve of the third expansion valve in the bypass circuit based on a refrigerant temperature TR (in) in a refrigerant inlet and a refrigerant temperature TR (out) in a refrigerant outlet of the water heat exchanger in a case of the electromagnetic valve being in an open state at the time of the defrosting operation.

Abstract: An image accumulation apparatus for retaining image information transferred via a communication line in an image storage section. The image accumulation apparatus includes a storage are management section for managing a storage area of the image storage section and a customer information management section for managing customer information concerning a customer making a request for storing the image information. The storage area management section acquires the maximum number of pixels of the image information, calculates the data capacity required for ensuring a predetermined number of images that can be retained for one customer from the maximum number of pixels, and sets the storage area.

Abstract: An image accumulation server has a storage area management section for managing a storage area of an image storage section and a customer information management section for managing customer information. The storage area is set to reserve a predetermined capacity as the initial state for one customer and after the expiration of a predetermined time period, the service providing contents for each customer including the storage area and usage charge in the next predetermined time period are again set in response to the customer information. If an unused area exists, in the next predetermined time period, the storage area is decreased and the usage charge is reduced or is made free of, or the storage area is decreased as much as the capacity corresponding to the usage charge, so that a part of the unused storage area is canceled as an equivalent for the usage charge.

Abstract: An image capture system includes a mobile camera phone and an image server connected to this mobile phone through a communication network. The mobile phone transmits subject type information of a next image capture session to the image server. The image server searches an image database for the images classified into the same subject type as received, and sends photographing position information of the retrieved images to the mobile phone. The mobile phone subsequently compares this photographing position information with a current position determined based on GPS signals, and displays a presence possibility of the desired subject within the area on a display panel. After the image capture, the mobile phone sends the captured image to the image server. The image server classifies and records the captured image into the image database according to the subject type information.

Abstract: A registration correction circuit for a solid-state camera having a plurality of solid-state image pickup elements. One of the color video signals produced from the image pickup elements is selected as a reference signal, and pixel data of the color video signals other than the reference signal are electronically moved so that the pixel data of all the color video signals will agree in their positions. Movement of pixels is carried out by using coordinate transformation and interpolation technique: the coordinate transformation is used to shift the pixels by a multiple of 1-pixel pitch; and the interpolation is used to shift the pixels by less than 1-pixel pitch. The spatial frequency components reduced by the interpolation calculations are adaptively enhanced for each pixel in real time.
