Abstract: A contour resonator is provided with a vibrating body formed from a flat plate in a square shape, excitation electrodes formed on both front and back surfaces of the vibrating body and regulating a resonance frequency, and temperature characteristic adjustment films formed on surfaces of the excitation electrodes and adjusting a temperature characteristic.

Abstract: A contour resonator reducing fluctuation of resonance frequency due to variety of a film thickness of an excitation electrode is provided. A counter resonator includes a quartz substrate and excitation electrodes respectively formed on front and back surfaces of the quartz substrate. There is a range where a frequency sensitivity with respect to an electrode film thickness is smaller than that in related art when a ratio Fe/Fb between a contour vibration frequency Fe of the excitation electrodes and a contour vibration frequency Fb of the substrate is larger than 0.69. That is, fluctuation of the contour vibration frequency with respect to variety of the electrode film thickness can be made small substantially.

Abstract: A contour resonator at least includes a first vibrating substrate and a second vibrating substrate having main surfaces that face each other and are bonded. The contour resonator includes a first excitation electrode provided on a front main surface of the first vibrating substrate, a second excitation electrode provided on a back main surface of the second vibrating substrate, and a common intermediate excitation electrode provided at an interface between the first vibrating substrate and the second vibrating substrate. The first excitation electrode and the second excitation electrode are electrically connected to constitute a first terminal. The intermediate excitation electrode constitutes a second terminal. The first vibrating substrate and the second vibrating substrate perform a contour vibration in accordance with an excitation signal applied between the first terminal and the second terminal.

Abstract: A product cost variance analysis system and method accurately calculates the cost of a product produced in a mixed production line, presents a factor of the cost variance in detail with accuracy, and provides information which can be effectively reflected in cost adjustment. Based on information integrally controlled in an integrated database, a target cost of a product is calculated and stored in the integrated database. Also, an actual cost of the product is calculated and stored in the integrated database. A difference between the target cost and the actual cost of the product is calculated and analyzed based on information from the integrated database. A variance for each item with difference by factor which is the cause of the difference is calculated, and then the results are displayed for each item respectively.

Abstract: An improved automatic vacuum dehydrating apparatus in a slurry carrying vessel including a hold for loading slurry therein provided with a plurality of dehydrating ports at its bottom is described herein, which comprises a dehydrating pipe branched at one end and connected to said respective dehydrating ports through respective closure valves individually provided in the respective pipe branches, a vacuum tank adapted to be evacuated and connected to the other ends of said dehydrating pipe, and pressure detector-controller means for detecting a pressure in the vicinity of each said dehydrating port and for controlling said closure valve in response to the detected pressure value.
