    Abstract: A piezoelectric resonator is provided which is capable of acquiring an excellent Q characteristic while letting a film thickness of an upper electrode be larger. The piezoelectric resonator has a lower electrode and an upper electrode with a piezoelectric film being sandwiched between them. By applying a voltage between the lower and upper electrodes to let a bulk acoustic wave propagate through inner portions of the piezoelectric layer, a signal having a specified resonant frequency is obtained. The standing wave has a first wave loop at an interface on a side opposite to the piezoelectric film of the upper electrode and a wave node and a second wave loop in inner portions of the upper electrode directing from the interface toward the piezoelectric film. The film thickness of the upper electrode obtained when a wavelength of a standing wave is defined as “λ” is 0.4 λ to 0.7 λ.

    Abstract: There is provided an automatic processing machine which comprises a processing-solution processing section in which a photographic photosensitive material is subjected to development processing, and a drying section for drying the photeosensitive material processed in the processing-solution processing section, particularly, an automatic processing machine in which an upper roller of conveying rollers or squeeze rollers, which are disposed at an upstream side of the drying section, is formed so that a contact angle of a water drop on a peripheral surface thereof is less than 135°, preferably 125°. The upper roller of silicone rubber in the conveying rollers or in the squeeze rollers includes a peripheral surface coated with a gelatin film. By conducting cross-linking using silicon for a long duration at the time of manufacturing silicone rubber, water repellency of the surface (that is, surface tension) is restrained and the contact angle of a water drop is thereby set to be less than 135°. Accordingly, the water drop does not remain spherical on the upper roller and is apt to be made flat. Namely, water is uniformly dispersed over the entire surface region of the upper roller and the formation of spot marks can be prevented.
