The cleats may or may not be interchangeable as wear and tear occurs and, if interchangeable, will be provided with a screw-type or other fastener in which the cleat itself has a portion formed with threads to engage corresponding holes in the sole of the shoe or a screw may be inserted through the cleat and into the sole of the shoe to fasten the cleat to the sole. Very little innovation has taken place in baseball or softball type cleats over the years. Innovation has primarily taken the form of the utilization of softer materials for use by children participating in the sports or the shortening of cleats for use on artificial turf surfaces. An electric-generating capacity which a solar cell can generate is determined depending on an irradiance level of a light and, for example, the electric-generating capacity when there is no irradiation of the light is zero. On the other hand, an electric power corresponding to an operation state of an electronic apparatus is required for a power source for driving the electronic apparatus irrespective of the irradiance level of the light. Therefore, it is obvious that the power source for stably driving the electronic apparatus cannot be composed of only the solar cell.
A hybrid power source system in which a solar cell and a secondary cell are combined with each other, and the secondary cell is used as an electric power buffer is known as a system in which a power source for stably driving an electronic apparatus is configured by using a solar cell. In this system, when the electric-generating capacity of the solar cell exceeds the electric power with which the electronic apparatus is driven, the secondary cell is charged in such a way that the excessive electric power which the solar cell generates is stored in the secondary cell. On the other hand, when the electric-generating capacity of the solar cell falls below the electric power with which the electronic apparatus is driven, the secondary cell is discharged so that the electronic apparatus is driven by the solar cell and the secondary cell.
The configuring of the hybrid power source system results in that there is no necessity for the solar cell to respond to a maximum power consumption of the electronic apparatus, and thus it is only necessary for the solar cell to supply the power consumption of the electronic apparatus on the average. As a result, it is possible to miniaturize the size of the solar cell. The hybrid power source system of the solar cell and the secondary cell can realize both of the stable supply of the electric power, and miniaturization of the solar cell, and thus

The cleats may or may not be interchangeable as wear and rip occur and, if interchangeable, will be provided with a screw - character or other fastener in which the cleat itself has a portion shape with threads to engage comparable hole in the sole of the shoe or a fuck may be inserted through the cleat and into the sole of the shoe to tighten the cleat to the sole. Very little innovation has taken place in baseball or softball type cleats over the years. invention has primarily taken the form of the use of softer materials for function by children participate in the sports or the shortening of cleats for use on artificial turf surfaces. An electric - generating capacity which a solar cellular telephone can generate is determined depending on an irradiance level of a light and, for example, the electric - generating capability when there is no irradiation of the light is zero. On the other hand, an electric power corresponding to an operation state of an electronic apparatus is required for a ability source for driving the electronic apparatus regardless of the irradiance degree of the lighter. Therefore, it is obvious that the power informant for stably drive the electronic apparatus cannot be composed of only the solar cellular telephone. 
 A hybrid power source system in which a solar cell and a secondary cell are combined with each other, and the secondary cell is used as an electric power buff is known as a arrangement in which a power source for stably driving an electronic apparatus is configured by using a solar cellular telephone. In this system, when the electric - generating capacity of the solar cell exceeds the electric power with which the electronic apparatus is driven, the secondary cell is charged in such a room that the excessive electric power which the solar cellular telephone generates is stored in the secondary cell. On the other hand, when the electric - generating capability of the solar cell fall below the electric power with which the electronic apparatus is drive, the secondary cell is discharged so that the electronic apparatus is driven by the solar cell and the junior-grade cell. 
 The configuring of the hybrid power source organization results in that there is no necessity for the solar cell to respond to a maximum ability consumption of the electronic apparatus, and thus it is entirely necessary for the solar cell to supply the might consumption of the electronic apparatus on the average. As a result, it is possible to miniaturize the size of the solar cellular telephone. The hybrid power source system of the solar cell and the secondary cell can realize both of the stable provision of the electric power, and miniaturization of the solar cell, and thus
