摘要： A multi-wavelength light source apparatus includes a tunable light source, optical intensity modulator, optical coupler, annular optical delay circuit, and optical gate device. The tunable light source successively changes and outputs a plurality of output lights different in wavelength from one another. The optical intensity modulator outputs a modulated signal light obtained by modulating an amplitude of the output light outputted from the tunable light source over a predetermined time. The optical coupler is optically connected to the optical intensity modulator, and receives the light outputted from the optical intensity modulator. The annular optical delay circuit is optically connected to the optical coupler, and delays a part of the output light outputted from the optical intensity modulator over a time longer than the predetermined time. The optical gate device is optically connected to the optical coupler, receives the output light outputted from the optical intensity modulator and the light passed via the annular optical delay circuit to open a gate at a timing and time width such that all of the signal light modulated over the predetermined time is included one by one for each of the plurality of wavelengths.

摘要： An acoustic wave device includes a piezoelectric substrate, an IDT electrode on the substrate, an internal electrode above the substrate, a side wall above the internal electrode, a lid on the side wall, an electrode base layer on the internal electrode, a connection electrode on the electrode base layer, and an anti-corrosion layer between the internal electrode and the side wall. The internal electrode is electrically connected to the IDT electrode. The side wall surrounds the IDT electrode. The lid covers the IDT electrode to provide a space above the IDT electrode. The electrode base layer is provided outside the space and the side wall. The anti-corrosion layer protrudes outside the side wall, and is made of material less soluble in plating solution than the internal electrode. This acoustic wave device prevents the internal electrode from breaking due to plating solution, hence being manufactured at a high yield rate.

摘要： An engine control device for detecting misfire of an engine. Based on a detected crank angle of the engine, an angular velocity at a first crank angle at which the engine speed is close to a minimum within one combustion cycle of each cylinder is calculated as a pre-combustion angular velocity, and an angular velocity at a second crank angle at which the engine speed is close to a maximum within the same combustion cycle is calculated as a post-combustion angular velocity. An amount of rotation variation caused between the first and second crank angles is calculated based on the pre-combustion and post-combustion angular velocities of the same combustion cycle, and is compared with a predetermined misfire criterion to determine whether or not misfire has occurred. When misfire is detected, a required operation is performed, for example, a warning lamp is turned on or the fuel supply quantity is increased.
