  • Publication number: 20080085216
    Abstract: A gas exchange chip comprises substrates (1,2); two flow channels (3,4) formed in the substrates (1,2) and each having an inlet port and an outlet port; and multiple grooves (9) interlinking the flow channels (3,4). The grooves (9) have the size of their sectional area predetermined and have at least a part of the internal surface thereof rendered hydrophobic so as to permit the transfer of gas component while inhibiting any liquid passage. A sample water containing carbon dioxide is caused to flow through one of the flow channels (3) while pure water is caused to flow through the other flow channel (4) to thereby transfer the carbon dioxide contained in the sample water into the pure water.

  • Patent number: 7183852
    Abstract: A differential amplifying apparatus includes first and second differential transistor pairs of different polarities operated by different constant currents, and first to sixth current mirror circuits. The second, third, fifth, and sixth current mirror circuits are connected to an output terminal. The first, second, and sixth current mirror circuits receive a first power supply voltage, and the third, fourth, and fifth current mirror circuits receive a second power supply voltage. The first and second current mirror circuits respectively output mirror currents based on respective corresponding currents flowing through the first differential transistor pair. The third current mirror circuit outputs a current input from the first current mirror circuit. The fourth and fifth current mirror circuits respectively output mirror currents based on respective corresponding currents flowing through the second differential transistor pair.

  • Patent number: 7148665
    Abstract: A direct current power supply apparatus includes a first power supply circuit and a second power supply circuit. The first power supply circuit converts a source voltage from an externally supplied direct current power source into a first voltage and provides the first voltage to an output terminal. The second power supply circuit converts the source voltage from the externally supplied direct current power source into a second voltage and provides the second voltage to the output terminal. The second power supply circuit is controlled to be turned on and off. The first power supply circuit detects voltage at the output terminal and, when the second voltage is not being provided because the second power supply circuit is inactivated, provides the first voltage.
