The present invention provides a method of fabricating a crystal oscillator with pedestal for surface mounting, which is provided on a base surface of a crystal oscillator from which a pair of lead wires extends and which is formed by injection molding using a mold with a liquid-crystal polymer as raw material; wherein protrusions that follow the shape of said mold are provided on at least a corner around the outer periphery of the surface of the oscillator pedestal facing said base surface of said crystal oscillator; a non-defective product is assumed to be one in which the upper surface of each of said protrusions is a flat surface, but a defective product is assumed to be one in which the flat surface of said protrusion is ridged; and only a non-defective product is mounted onto the base surface of the crystal oscillator. This makes it possible to provide a method of fabricating a crystal oscillator by which reliability is increased while the strength of the oscillator pedestal is maintained.

A piezoeletric resonator includes: a substrate; a lower electrode formed on or above the substrate; a piezoeletric body formed on or above the lower electrode; an upper electrode formed on or above the piezoeletric body; and a cavity under a vibrating portion formed by the lower electrode, the piezoeletric body, and the upper electrode. Where a resonant frequency of vibration with a thickness of the vibrating portion being a half of a wavelength is taken as fr, an average of ultrasonic velocity in a material forming the cavity is taken as Vc, and a value determined based on the resonant frequency fr and the average of ultrasonic velocity Vc is taken as λc (=Vc/fr), a depth of the cavity is set so as to be equal to or larger than n×λc/2−λc/8 and equal to or smaller than n×λc/2+λc/8.

A power semiconductor device comprises a semiconductor substrate, a gate electrode region (control electrode region), a cathode electrode region (first main electrode region), an anode electrode region (second main electrode region) and a guard ring. The semiconductor substrate has a side surface portion having a vertical portion formed substantially vertical to a main surface and a mesa portion connected to the vertical portion in a cross section. The gate electrode region is formed in a first main surface of the semiconductor substrate. The cathode electrode region is formed in part of a surface of the gate electrode region. The anode electrode region is formed in a second main surface of the semiconductor substrate. The guard ring is formed in the second main surface of the semiconductor substrate and annularly surrounds the anode electrode region. With this constitution provided is a power semiconductor device which makes the impurity diffusion length of the anode electrode region shallower in order to ensure reduction in recovery loss.

The invention provides a combustion apparatus which can inhibit an NOx generation even in the case of promoting a mixing between a high-temperature combustion gas and an air so as to intend to reduce an unburned combustible. In a combustion apparatus provided with a burner burning a fuel within a furnace in a theoretical air ratio or less, and an air port supplying a combustion air for a shortfall in the burner, a supply apparatus for supplying a nitrogen oxide generation inhibiting gas is provided in a mixing region between the both or near the mixing region. Further, the invention provides a wind box which can inhibit an NOx generation even in the case of promoting a mixing between a high-temperature combustion gas and an air so as to intend to reduce an unburned combustible. In a wind box having an air port arranged in a back flow side of the burner and supplying a combustion air for a shortfall in the burner, a supply apparatus for supplying a nitrogen oxide generation inhibiting gas is provided in a mixing region between the both or near the mixing region.
