Abstract: The upper block 12 contacts the bearing block 20, and the bearing block 20 is coupled to the upper plate 21. The upper block 12 has a protruding part 22 on the upper surface that is worked into a convex surface with a radius of R1, and the bearing block 20 has a recessed part 23 in the undersurface that is worked into a concave surface with a radius of R2 (R2>R1). As a result of such a construction being used, the pressing surface of the upper pressing plate 15 always conforms to the surface of the quartz crystal substrate 11 during pressing, so that a uniform load is applied to the quartz crystal substrate 11. As a result, the surface of the quartz crystal can be uniformly pressed in the hot pressing method.

Abstract: Side plates (4) each include a base portion (41), in contact with fins (11), and side wall portions (42) extending from the base portion (41) in the direction Y in which tubes (10) are stacked. The side wall portions (42) are formed with a bent deforming portion (421) to facilitate extension/shrinkage, of the side wall portions (42), in the longitudinal direction (X) of the tubes (10). The base portion (41) is formed with a pair of hooks (411) extending toward the surface of the bent deforming portion (421) in opposed relation to the base portion (41). In the case where the base portion (41) tends to be displaced, the hooks (411) come into contact with the bent deforming portion (421) to thereby suppress or prevent the displacement of the base portion (41).

Abstract: Rectangular protruding parts 2 are formed on the surface of one side of a quartz crystal substrate 1; these protruding parts 2 are formed as aggregates of rectangular protruding parts 4 of an even finer pattern. Recessed parts 5 which are lower than the surfaces of the protruding parts 4 are formed between the protruding parts 4; however, the width of these recessed parts 5 is narrow, so that when the protruding parts 4 are viewed on the macroscopic scale, numerous protruding parts 4 are aggregated, and appear to form single protruding parts 2. Such a quartz crystal substrate 1 is clamped between heater blocks from above and below, and the temperature of the quartz crystal substrate is elevated. At the point in time at which this temperature reaches a desired temperature, the substrate 1 is pressed by means of a press. Consequently, stress acts only on the portions corresponding to the protruding parts 4, so that the crystal axis components are inverted only in these portions.
