A piezoelectric resonator of the present invention is structured such that on a substrate 5 having a cavity 4 formed therein, a lower electrode 3, a piezoelectric body 1, a spurious component control layer 16, and an upper electrode 2 are formed in this order from bottom up. The spurious component control layer 16 is a layer for controlling a spurious frequency, and composed of, for example, a metallic material, a dielectric material, or a piezo electric material. By additionally providing the spurious component control layer 16, it is made possible to cause variation of the spurious frequency due to unwanted variation to become greater than variation in resonance frequency of the main resonance of the piezoelectric resonator. Thus, it is possible to realize a piezoelectric resonator having an admittance frequency response where no spurious component occurs between resonance frequency fr and antiresonance frequency fa.

An electric arc device and methods to build up, clad, join, or overlay an alloyed metal onto a parent metal with minimal admixture. The methods employed in the electric arc device provide a high frequency waveform with a high amplitude pulse, a low amplitude background current, and a special shorting routine, to alleviate the problem of generating too much ad-mixture. A fast transition from a peak current level to a background current level along with a shorting response and a plasma boost pulse reduces the droplet size and reduces the heat input required to achieve good welding performance.

In a plasma film forming apparatus, two first electrodes 51 connected to a power source 4 and two grounded second electrodes 52 are arranged in the order of the second electrode 52, the first electrode 51, the first electrode 51 and the second electrode 52. A first flow passage 50a formed between the central first electrodes 51 allows a raw material gas (first gas) for being formed into a film to pass therethrough. A plasma discharge space 50b of a second flow passage formed between the first and second electrodes 51, 52 on the both sides allows an excitable gas (second gas) to pass therethrough, which excitable gas is exited by plasma such that the raw material can be formed into a film, but that the excitable gas itself is merely excited but not formed into a film. Those gases are converged at a crossing part 20c between the first and second flow passages and blown off via a common blowoff passage 25a. By this, the apparatus composing members such as electrodes can be prevented from being adhered with a film.

The insulation layer, the second liner, the mask layer and the pad oxide layer outside the trench are eventually removed.
