Abstract: A crystal blank includes a vibrating arm which extends in a direction intersecting the polarization direction. In at least one of the upper surface and lower surface which are parallel to the direction of extension of the vibrating arm and run along polarization direction, the vibrating arm is provided with two recesses (grooves) in the width direction of the surface thereby having a pair of outer walls which are positioned on the two sides of the two recesses and a middle wall which is positioned between the two recesses. In the middle wall, the apex part is located at a position lower than the apex part of each of the pair of outer walls and is thinner than each of the pair of outer walls at the same heights.

Abstract: To provide a tuning-fork type quartz crystal vibrating element capable of decreasing changes in oscillation frequencies before and after being mounted. The tuning fork element includes: a base part; a pair of vibration arm parts extended in a same longitudinal direction from the base part; and respective weight parts located at the tips of the vibration arm parts. Provided that, on a plan view, a measurement in the longitudinal direction is length, and a measurement in a direction perpendicular to the longitudinal direction is width, Expression (1) ?100?x?100, ?30?y?30, and ?0.3x?15?y??0.3x+15 applies, where a difference between the length of the vibration arm parts together with the respective weight parts and the reference value x0 is x, a difference between the width of the weight parts and the reference value y0 is y, and the unit is ?m.

Abstract: A tuning fork type crystal blank includes a base part, a pair of vibrating parts which extend from the base part parallel with each other, an auxiliary part including a support part located on one side of an alignment direction of the pair of vibrating parts relative to the base part and pair of vibrating parts and extending parallel with the pair of vibrating parts, and a holding part which is located on the opposite side to the pair of vibrating parts relative to the base part and connects the base part and the support part. When viewed in a planar view direction perpendicular to the alignment direction and to the direction in which the pair of vibrating parts extend, cut away part is formed in a side surface of the auxiliary part.

Abstract: Uniform emulsions of fluorinated liquid droplets in water are formed from SPG (Shirasu porous glass) membrane emulsification. The fluorinated oil-in-water emulsions exhibit unusually stability, as the much denser fluorinated liquid droplets do not coalesce at least 3 month after emulsification. A subsequent polymerization of monomer mixtures of the fluorinated droplets yields uniform polymeric microspheres encapsulating the fluorinated fluid. The use of expanded PTFE membrane emulsification forms water-in-oil emulsions with uniform liquid droplets, especially when small amount of fluorinated liquid is present in the oil phase.
