摘要： There is provided a pressure detection device including: a pressure detection element which receives pressure so as to output a detection signal corresponding to the pressure P; and a processing circuit which processes and outputs the detection signal output from the pressure detection element, where the processing circuit includes: a voltage transformation circuit which only transforms a power supply voltage fed from an external power supply so as to obtain a first reference voltage with a predetermined voltage value; an integrator circuit which uses the first reference voltage as an operation reference to perform integral processing on the detection signal so as to convert the detection signal into a voltage waveform; and at least one or more amplifier circuits which use a second reference voltage with a predetermined voltage value as an operation reference to perform amplification processing on an output signal from the integrator circuit.

摘要： A sample loading plate that includes at least one sample mounting spot that mount a sample thereon is provided with a substrate having a conductive surface and an insulating film that is laminated on the conductive surface of the substrate and that has at least an insulating surface, the insulating film being sparsely formed so that the conductive surface of the substrate is partially exposed at least in the sample mounting spot. Thus, a voltage applied to the sample loading plate can effectively place the sample in an electric field. As a result of which, in a mass spectrometric analysis of the sample, there is no charge up of the sample and appropriate ionization becomes possible.

摘要： New classes of thiadiazole and oxadiazole compounds for use in LC mixtures are disclosed. In an embodiment, the new classes of thiadiazoles and oxadiazoles comprise at least one phenyl ring attached to the heterocyclic ring, where no alkyl, alkenyl or alkynyl tails are attached to the phenyl ring, but one alkyl, alkenyl or alkynyl tail is attached to the other end of the molecule, and a fluoro or cyano group appears in the para position of the phenyl ring. These compounds are disclosed as being effective at inducing smectic A phases in liquid crystal mixtures, particularly in liquid crystal mixtures also possessing a smectic C phase, more particularly in materials possessing a chiral smectic C (ferroelectric) phase.

摘要： In piezoelectric sensors, conventional amplification factor adjustment methods involving the cutting of a wiring pattern or use of a laser trimmable resistor are unable to adjust the amplification factor when the sensor is in a completed state. As a result, the production process becomes complex and production costs increase. Further, because the amplification factor adjustment is carried out in a different state from that of the finished product, the problem that the amplification factor is not set correctly in the finished product also occurs. A non-volatile memory is incorporated in an integrated circuit in which are integrated piezoelectric sensor circuit elements. The amplification factor is adjusted by writing data from a writing terminal to change an amplification resistor.
