Abstract: An air-conditioning apparatus includes an outdoor unit including a compressor configured to compress refrigerant, a relay unit connected to the outdoor unit, and an indoor unit connected to the relay unit. The compressor is driven to circulate the refrigerant between the outdoor unit, the relay unit, and the indoor unit. The air-conditioning apparatus includes a supplementary heat source unit in parallel with the indoor unit and connected to the relay unit. The outdoor unit includes an outdoor heat exchanger configured to exchange heat between the refrigerant flowing through the outdoor heat exchanger and a fluid. The supplementary heat source unit includes a supplementary heat exchanger configured to exchange heat between the refrigerant flowing through the supplementary heat exchanger and hot water.

Abstract: An information processing device including a determining unit for determining whether a registrant who registers electronic credit information for a provider to an electronic credit server is same as an issuer who issues electronic credit, based on payment information; a comparison unit for comparing the payment information with information stored in a customer master DB while switching a reference destination of the information between a case where the registrant is different from the issuer and a case where the registrant is the same as the issuer, depending on a determination result; a retrieval unit for retrieving, depending on a comparison result, information on the registrant of the electronic credit based on the payment information; and a providing unit for providing, upon determining that the comparison is successful, the information that is retrieved by the retrieval unit as electronic credit collecting information.

Abstract: A semiconductor device which can reduce the peak value of the rush current generated during a transition from resume mode to normal mode. The semiconductor device has a plurality of daisy-chained memory modules. Each of the memory modules includes a memory array, a switch for controlling, in resume mode, source voltage supply to a constituent element of the memory module, and a delay circuit which receives a resume control signal ordering a transition from resume mode to normal mode and outputs a resume control signal delayed from the inputted resume control signal to the memory module of the next stage.

Abstract: A resonant type switching power source implementing zero voltage switching on the basis of the resonance between an inductor and a capacitor. A main switch is connected to the primary side of a main transformer. A pulse width control circuit generates a control signal for varying the turn-on time of the main switch until the output voltage of the secondary side of the tranformer being fed back reaches a predetermined value. A resonance capacitor is connected in parallel with the main switch. When the terminal voltage of the capacitor crosses zero potential toward the negative side, the pulse width control circuit delivers an ON command to the main switch. Alternatively, the ON control over the main switch may begin at a time a predetermined period of time later than the time for turning on the resonant circuit.
