摘要： A method of directly bonding a crystal to a crystal includes the steps of mirror-polishing the surfaces of the crystals and then rinsing them with a cleaning material and then affecting a baking operation and then bonding them together and thereafter annealing them within a temperature range where crystal crystallization is not transited in phase so that a further strong bonding force is obtained. A crystal resonator is obtained where electrodes are oppositely established across a ply crystal blank with at least two sheets of crystal blanks having a desired cut angle and a desired thickness being directly bonded so that the respective crystal axes intersect at the desired angles. The ply crystal blank may have a central portion which is either thicker or thinner than a surrounding portion. A crystal oscillator including a crystal resonator having the above noted features may be fabricated and a temperature compensated crystal oscillator of either the analog or digital type may also be formed using such a crystal resonator. A crystal filter may also be formed using a ply crystal bank with at least two sheets of crystal blanks having a desired cut angle and a desired shape being directly bonded so that respective crystal axes intersect at the desired angles.

摘要： An engine generator is disclosed in which an engine drives a generator and causes a cooling fan to rotate to cool the generator. The generator includes an intake duct having an intake port provided in a lower portion thereof and oriented downward. Moisture-containing outside air sucked through the intake port impinges on a barrier plate disposed in the intake duct. The barrier plate is located above the intake port and faces the intake port. The moisture adheres to the barrier plate in the form of water droplets, which then fall toward the intake port after having separated from the outside air.

摘要： A high-frequency switch having two input terminals and two output terminals of which a broad pass band is required has (i) a circuit board that has two input electrodes along one side and two output electrodes along another side, and (ii) four PIN diodes mounted on this circuit board. Each side of the quadrangle made by connecting the input electrodes and the output electrodes is not parallel to the corresponding side of the quadrangle made by connecting electrodes for mounting the PIN diodes. Each side and the corresponding side form an angle other than 180°. This structure can provide a high-frequency switch capable of reducing a transmission loss in the paths and facilitating impedance matching.
