  • Patent number: 9520278
    Abstract: An object is to mix multiple liquids sufficiently and then nebulize the mixed liquids while maintaining the nebulizing efficiency. A nebulizer includes a first inner tube disposed inside an outer tube and having therein a first sample passage through which a first liquid sample flows, a second inner tube disposed inside the outer tube in parallel with the first inner tube and having therein a second sample passage through which a second liquid sample flows, a membranous member disposed with a gap between the membranous member and sample outlets formed at respective ends of the inner tubes. The gap forms mixing space in which a gas passing through a gas passage converts the first and second liquid samples flowing out of the sample outlets into droplets and mixes the droplets and the membranous member has multiple holes through which the mixed liquid samples pass along with the gas.

  • Patent number: 8397003
    Abstract: There are provided a CPU connection circuit and a method by two CPUs by alternately conducting a changeover between two buffers disposed there between to prevent an event that data processing cannot be fully executed by the CPU on the receiving side. There is included a memory controller which monitors whether or not an amount of data stored by a CCPU 1 in either one of buffers 301 and 302 reaches a predetermined threshold value; when the amount of data stored by the CCPU 1 in the buffer 301, 302 reaches the threshold value, the memory controller requests an ACPU 2 to acquire the data stored in the buffer and changes the storage destination of data from the CCPU to the other one of the buffers; the threshold value is a value more than a unit quantity of data which the CCPU 1 sends to the buffer 301, 302.
