Abstract: To reliably prevent knocking in all of the cylinders of a multicylinder engine by detecting an output signal from a knock sensor provided for only one of the cylinders. A cylinder barrel is formed with a knock sensor base on the side surface of only the third cylinder and a vibration type knock sensor is mounted on the knock sensor base. A water jacket is formed in an upper portion of the wall of the cylinder barrel. The knock sensor base is formed below the water jacket so as to prevent a problem such that knocking vibrations may be absorbed by the cooling water in the water jacket to cause a reduction in sensitivity of the knock sensor.

Abstract: A nebulizer includes a piezoelectric transducer for aerosolizing a drug solution in a disposable cup module disposed above the transducer. Acoustic waves generated by the transducer propagate sequentially through transmitting medium, a first barrier, coupling medium, and a second barrier that forms part of the cup module, and into the interior of the cup module. The transducer at least partially comprises silver. The silver fluidly contacts the transmitting medium to discourage bacteria growth in the transmitting medium. The device includes electronics components that drive the transducer and measure an electrical characteristic associated with the transducer during operation. The electronics components measures changes in the electrical characteristic to determine when the drug solution level falls below a predetermined threshold, and deactivates the device accordingly.
