Abstract: A timepiece comprising a generator (1) for generating a supply voltage of a first predetermined value U.sub.1, a barrel with a spring (5, 6), a winding mechanism (5') and a set of hands (7 to 9). The electronic circuit (11, 12) of the timepiece requires a minimum limited supply voltage having a second predetermined value U.sub.2. This circuit comprises a timebase (12) and a regulating circuit (11) for regulating the rotational speed of the generator. According to the invention, a voltage regulator (25) is connected between the generator and said electronic circuit for adjusting its output voltage to said limited second value U.sub.2. The ratio between the absolute value U.sub.1 of the predetermined first value U.sub.1 and the second predetermined value satisfies the relationship U.sub.1 =k.multidot.U.sub.2, k being a factor corresponding at least to the maximum expected variation rate of the absolute value U.sub.1 when the timepiece is worn.

Abstract: A pair of first and second concrete layers (1, 2) spaced away from each other by a certain distance are connected to each other through a corrugated plate (3) having a uniform magnitude of amplitude so that there are formed a space between the concrete layers (1, 2). A weight of a concrete-made panel is decreased by this hollow structure. A corrugated plate (3) is designed to have a trapezoidal cross-section of rectangular corrugation. By sinking mountain and valley portions of the corrugated plate into the first and second concrete layers (1, 2), the concrete-made panel can have enhanced compressive strength in a direction of corrugation of the corrugated plate (3), and have enhanced rigidity because of diagonal members of a truss which keeps the concrete-made panel being kept to be a plane.
