  • Patent number: 12130270
    Abstract: An object of the present invention is to detect ammonia with high sensitivity and high selectivity using a nanomechanical sensor with a structure that is as simple as possible. A method for detecting ammonia according to an embodiment of the present invention comprises supplying a sample gas possibly containing ammonia to a nanomechanical sensor that detects a stress or a displacement using poly(methyl vinyl ether-alt-maleic anhydride) as a material of a receptor layer, and detecting presence or absence of ammonia or a content of ammonia in the sample gas based on an output signal from the nanomechanical sensor, in which the sample gas is a humidified sample gas with controlled relative humidity.

  • Publication number: 20070263544
    Abstract: There is provided a system that uses a network matrix to carry out a search for shortest paths from a starting node included in a network having a plurality of nodes to other nodes. The network matrix includes link costs of links and each link has a root end that is a node included in the network and a tail end that is another node connected to the root end.

  • Patent number: 6088063
    Abstract: There occurs an output timing lag between audio and video, for example, in case of building a system. Excessive frame skipping, etc. occurs. Prior to comparing a PTS and an SCR of MPEG within an apparatus, an offset value is added to the value of PTS. A minus offset value is used for a fast decode process. Offset values are written into an audio offset value register etc. by a host CPU. A value obtained by adding PTS and an offset value and an internal clock SSC depending on an SCR are compared by an adder-subtracter. If comparison shows the decode process is still fast, a decision controller instructs, for example, display of the same frame twice.

  • Patent number: 5726371
    Abstract: In a musical tone waveform generation apparatus for outputting musical tone signals generated by a software program at predetermined time intervals, sound source methods can be selected in units of tone generation channels. In the musical tone waveform generation apparatus, the sound source method or the tone color of a musical tone signal to be output is determined in accordance with performance data (pitch data, touch data, music part data, and the like). A musical tone signal is generated by CPU upon execution of a sound source processing program, associated with a modulation method stored in a memory. The generated musical tone signal is output at predetermined time intervals. As for sound source processing based on the modulation method, at least one operator processing, and algorithm processing for determining an input/output relationship among the operator processing operations are independently executed.

  • Patent number: 5691493
    Abstract: A main CPU and a sub CPU take share of executing a tone generating process to generate multiple tone signals on a real-time basis without using an exclusive tone generator. The main CPU and sub CPU are formed on a one-chip LSI, thus facilitating realization of a compact electronic musical instrument. According to another structure, the main CPU executes tone generation while the sub CPU performs an effect process, thereby permitting a one-chip LSI to generate an effect-added musical tone.
