摘要:
A solar cell includes a p-n junction formed by joining a p-type semiconductor and an n-type semiconductor. The p-type semiconductor is a chalcopyrite compound semiconductor with a band gap of 1.5 eV or more within which an intermediate level exists with a half bandwidth of 0.05 eV or more. The intermediate level is different from an impurity level. The chalcopyrite compound semiconductor includes a first element having first electronegativity of 1.9 or more in Pauling units, the first element occupying a lattice site of the semiconductor. A portion of the first element is substituted with a second element having second electronegativity different from the first electronegativity, the second element being a congeneric element of the first element. The intermediate level is created by substituting the first element with the second element.

When a temperature of feed air blown into a space for air conditioning cannot be increased up to the target temperature in an indoor condenser of a heat pump cycle included in a gas injection cycle, the volume of the feed air flowing into the indoor condenser is decreased. Thus, the temperature of the refrigerant condensed by the indoor condenser is increased, while the amount of a compression work in a high-pressure side compression stage of the compressor is increased, which suppresses the lack of the heating capacity of the feed air blown into the space for air conditioning.

A unified heat exchanger includes a first heat exchanging arrangement and a second heat exchanging arrangement. The first heat exchanging arrangement is adapted to exchange heat between high pressure refrigerant and conditioning air. The second heat exchanging arrangement is adapted to exchange heat between low pressure refrigerant and the conditioning air. The first heat exchanging arrangement and the second heat exchanging arrangement are integrated together and are arranged to enable heat exchange of the conditioning air with both of the high pressure refrigerant and the low pressure refrigerant.

A speaker comprising a first rod magnet having a longitudinal direction, a second rod magnet having a longitudinal direction parallel with the longitudinal direction of the first rod magnet, a third rod magnet forming a second magnetic gap between it and the first rod magnet, a diaphragm vibrating in the vibrating direction, a housing for storing the first rod magnet, the second rod magnet, the third rod magnet and the diaphragm, and voice coils bonded to the diaphragm and arranged in first and second magnetic gaps. The second rod magnet has a longitudinal direction parallel with the longitudinal direction of the first rod magnet, and has the opposite end faces in the longitudinal direction. The third rod magnet has a longitudinal direction parallel with the longitudinal direction of the first rod magnet, and has the opposite end faces in the longitudinal direction. The diaphragm is located between the first and second rod magnets and between the first and third rod magnets. The housing forms a first space surrounded by one of the opposite end faces of the second rod magnet and one of the opposite end faces of the third rod magnet, and forms a second space surrounded by the other of the opposite end faces of the second rod magnet and the other of the opposite end faces of the third rod magnet. The housing is composed of a nonmagnetic body and supports the outer circumference of the diaphragm. First and second sound radiating holes respectively facing the first and second spaces are formed in the housing. This speaker is thin and can deliver big sound.

摘要:
An automotive air conditioning system has a primary hot water circuit 11 located on a side where a vehicle installed heat generator 10 is located and a secondary hot water circuit 13 which includes a hot water type heater core 12 for heating passenger compartment outlet air, whereby when in a heating mode, in the event that a coolant temperature TW1 of the primary hot water circuit is lower than a coolant temperature TW2 of the secondary hot water circuit 13, an opening and closing valve 26 is closed, whereas an opening and closing valve 23 is opened, so that a state is created in which the hot water circuits 11, 13 are separated from each other. On the other hand, in the event that the coolant temperature TW1 of the primary hot water circuit becomes higher than the coolant temperature TW2 of the secondary hot water circuit 13, the opening and closing valve 26 is opened, whereas the opening and closing valve 23 is closed, so that a state is created in which the hot water circuits 11, 13 are connected to each other.
摘要:
The present invention relates to a loudspeaker in the acoustic field and the information communication field. The invention provides a loudspeaker that can realize a thinner size. To achieve this, the loudspeaker of the present invention is structured so that a part of a diaphragm is inserted to a dent or an opening formed at the center poles of a lower plate of a magnetic circuit. This structure allows the diaphragm to be stored within the height of the magnetic circuit, thus allowing the loudspeaker to have a thinner size.
