An engine oil deterioration detection apparatus includes a sensing capacitor CS formed of paired electrodes dipped into engine oil whose deterioration is to be detected, the engine oil deterioration detection apparatus detecting deterioration of the engine oil on the basis of a change in electrostatic capacitance of the sensing capacitor CS. The apparatus comprises a generation unit configured to generate a named shared memory that can be accessed by both an application which runs with a first bit number and a printer driver which runs with a second bit number different from the first bit number. One end of the exhaust tube is to be connected to a first exhaust component and a second end of the exhaust tube is to be connected to a second exhaust component such that the exhaust tube forms a sole exhaust path between the first and the second exhaust components. The sound being generated by this device, commonly known as an acoustic generator, comes from the energy released by the equilibration of the different gas pressures. In this way the heat load on the substrate table can be reduced and dummy structures can fill a mouse bite without overlapping an alignment mark. A gain set value is calculated with which an amplitude value of the baseband signal outputted from a level adjustment circuit is adjusted to an amplitude value matching a dynamic range of a DA converter based on transmission code number information transmitted from a signal processor.
