摘要： PROBLEM TO BE SOLVED: To provide a piezoelectric generated light emitting marker to be charged with an existing electronic circuit and subjected to inexpensive switching supply therewith instead of a light emitting circuit, while solving the problem on a conventional piezoelectric generated light emitting marker with a guide track of a weight to be moved as a linear track, when mounted in use on the wheel of a bicycle or a rotator, that force works on the weight to be moved to the end of the linear track to preclude the movement of the weight after moved to the end of the guide track and cause the impossible generation of electric power. SOLUTION: The piezoelectric generated light emitting marker, in which the guide track of the weight has a certain radius of curvature or is curved at a radius of curvature being the same as a distance from a position where it is mounted on the wheel or the rotator to a center of rotation, is used to generate less force on the weight to be moved to the end of the guide track even when centrifugal force works on the weight. A switch is mounted on the track of the weight to be moved. Otherwise, a switch is provided at the end of the guide track of the weight for switching on or off upon collision of the weight to permit inexpensive switching supply with an electronic circuit.

摘要： PROBLEM TO BE SOLVED: To solve the problem of rotation being unable to be started, when the force of wind does not reach a fixed value of larger since activation torque for activating the rotation for attraction or repulsion between magnets is large, even if rotation is stopped once in a state, without wind and then wind blows in a wind power system for using the attraction and repulsion of the magnets in a relatively small rotor, where a diameter is limited to give distortion to a piezoelectric element in an indicator, where dimensions are limited. SOLUTION: The number of magnets 5 being mounted to a rotati mechanism and the number of piezoelectric elements 7 should be set to at least two, so that the number of pairs in a moment when magnetic force for operating between opposite magnets 5 and 6 in a rotary process becomes maximum is set to plural, and adjustment is carried out so that repulsion operates in some pairs and attraction force operates in other pairs, thus solving the problem; further, recharging electrical energy where the piezoelectric element 7 emits light in a recharger, and hence taking out the electric energy as needed for supplying to a phosphor.

摘要： PROBLEM TO BE SOLVED: To provide a decorative light, which makes the supplying of electric power from outside such as a commercial power source, a cell battery or the like unnecessary and which can use semi-permanently and has a plenty of durability. SOLUTION: This decorative light consists of a piezoelectric bimorph, which is formed by cementing two square plate-like piezoelectric elements and both the sides of which have electrodes and one end of which is fixed to a easing and to the other end of which a weight is mounted directly or through an elastic body oscillatorily, under the condition that the electrodes of non-cemented surface and at least one or more light emitting diodes are electrically connected together. Further, this decorative light is equipped with stopping mechanisms for suppressing the displacement due to the stress applied to the casing through the oscillation of the weight of the piezoelectric bimorph. Furthermore, this decorative light is equipped with a hook for fixing the casing to a matter to be decorated.
