  • Patent number: 8776821
    Abstract: A method comprises transporting a first stream of a carrier gas to a delivery device that contains a solid precursor compound. The first stream of carrier gas is at a temperature greater than or equal to 20° C. The method further comprises transporting a second stream of the carrier gas to a point downstream of the delivery device. The first stream and the second stream are combined to form a third stream, such that the dewpoint of the vapor of the solid precursor compound in the third stream is lower than the ambient temperature. The flow direction of the first stream, the flow direction of the second stream and the flow direction of the third stream are unidirectional and are not opposed to each other.

  • Patent number: 8770035
    Abstract: A semiconductor pressure sensor (720) includes a thin film piezoelectric element (701) which applies strain to a portion of a semiconductor substrate that corresponds to a thin region (402). The thin film piezoelectric element (701) is formed at a distance away from diffusion resistors (406, 408, 410, and 412) functioning as strain gauges and is extended to the proximity of a bonding pad (716A) connected to an upper electrode layer of the thin film piezoelectric element and a bonding pad (716F) connected to a lower electrode thereof. The diffusion resistors (406, 408, 410, and 412) constitute a bridge circuit by metal wiring (722) and diffusion wiring (724). During self-diagnosis, a prescribed voltage is applied to a thin film piezoelectric element (701). If the output difference of the bridge circuit between before and after the voltage application falls outside a prescribed range, it is determined that a breakage occurs in the semiconductor pressure sensor (720).

  • Patent number: 8766616
    Abstract: The present invention provides a comparator with novel output logic. The comparator makes a comparison between an input voltage and a reference voltage. A differential amplifying circuit includes a first input transistor with a control terminal applied with the reference voltage and a second input transistor with a control terminal applied with the input voltage. An output section receives an export signal of the differential amplifying circuit and outputs an output signal that corresponds to the export signal and denotes a result of the comparison. A feedback circuit receives the output signal of the output section, and if the output signal is changed from a first level to a second level, the output signal feeds back to the differential amplifying circuit or the output section while it is restored to the negated level.
