Abstract: A diagnosis circuit makes a diagnosis of a first multiplexer. The first multiplexer receives input data elements, selects one of the input data elements, and outputs the selected one as a selected data element. The diagnosis circuit includes a comparator unit and a second multiplexer. The comparator unit compares each of the input data elements to be supplied to the first multiplexer with the selected data element provided by the first multiplexer. The second multiplexer receives comparative data elements corresponding one to one to results of comparison made by the comparator unit with respect to the input data elements and outputs, out of the comparative data elements, a comparative data element, including a result of comparison between the one input data element selected by the first multiplexer and the selected data element, as a result data element.

Abstract: A signal processing device includes detection circuitry and correction circuitry. The detection circuitry includes a first detection unit and a second detection unit. The first detection unit generates at least one detection signal based on an associated one of output signals corresponding to each of at least two directions. The second detection unit has a broader detection range than the first detection unit and generates at least one correction signal based on the associated one of the output signals corresponding to each of the at least two directions. The correction circuitry corrects an associated one of the detection signals corresponding to each of the at least two directions with at least an associated one of the correction signals corresponding to at least one direction, other than one direction subjected to correction, out of the at least two directions.

Abstract: A fin-and-tube heat exchanger comprises: fins (31) which each have flat sections (35), first sloped sections (36), and second sloped sections (38); and heat transfer pipes (21). If a flat plane which is in contact, from the side opposite the crest of a ridge (34), with the upstream end and downstream end of the first sloped sections (36) in the air flow direction is a reference flat plane (H1), the angle between the reference flat plane (H1) and each of the second sloped sections (38) measured in a region upstream of a through-hole in the air flow direction is θ2, then the range of θ2 is determined by the relationship θ°

Abstract: An inertial detection circuit includes a signal generator and a processing unit. The signal generator includes a drive voltage generator and a test voltage generator. The drive voltage generator applies to the fixed electrode a drive voltage with a first frequency. The test voltage generator applies to the fixed electrode a test voltage with a second frequency lower than the first frequency. The processing unit includes a detection processor and a diagnostic processor. The detection processor performs a detection processing of detecting a capacitance between the fixed electrode and the moving electrode based on a detection signal. The diagnostic processor performs a diagnostic processing of diagnosing abnormality of the detector based on a diagnostic signal.

Abstract: An A/D converter includes an A/D conversion unit and an output unit. The A/D conversion unit includes a second A/D converter (successive approximation register A/D converter) and generates first digital data having a first number of bits and second digital data having a second number of bits, where the second number of bits is smaller than the first number of bits. The output unit provides first output information that is the first digital data and also provides second output information based on the second digital data. The output unit provides the second output information before providing the first output information.

Abstract: A digital filter is used in an A/D converter and includes a first filter and second filter. The first filter outputs first digital data by performing filter processing on output of an A/D conversion unit included in the A/D converter. The second filter outputs second digital data by performing filter processing on the output of the A/D conversion unit. The second digital data has either a lower resolution or a smaller effective number of bits than the first digital data does. The second filter outputs the second digital data before the first filter outputs the first digital data.

Abstract: A signal processing device includes a detection circuit, a correction circuit, and a comparator circuit. The detection circuit generates a first detection signal, based on an output signal of a capacitive detection element that detects inertial force. The correction circuit corrects non-linearity of the first detection signal and outputs a second detection signal thus corrected. The comparator circuit compares the first detection signal and the second detection signal with each other and outputs a comparison signal representing a result of comparison.
