    • There is provided a baseball bat that has performance similar to that of the conventional wooden bat and moreover is excellent in terms of cost and resource conservation. For this baseball bat 11, a reinforcing core 12 having a rectangular cross section is arranged in the center of the cross section thereof continuously so as to penetrate both end thereof, bamboo pieces 24 are laminated around the reinforcing core 12, and an adhesive is caused to permeate into the contact surface between the reinforcing core 12 and the bamboo pieces 24 evenly under a pressure, by which firm bonding can be attained. In addition, by using a material that is hard and has a large specific gravity as compared with bamboo, such as hickory or reinforced wood, as the reinforcing core 12, the flexural rigidity is enhanced as a whole, and the weight is increased. Therefore, the characteristics and feel in use are improved as compared with the conventional bamboo bat, and the baseball bat 11 can be used as a substitute for a wooden bat. Bamboo, hickory, and reinforced wood have no problem in terms of resource conservation, can reduce the product price, and can lower the consumption of scarce resources such as serrata.
    • 提供了一种具有与常规木蝙蝠类似的性能的棒球蝙蝠,而且在成本和资源节约方面也是优秀的。 对于该棒球棒11,具有矩形横截面的加强芯12连续地布置在横截面的中心,从而贯穿其两端,竹节24层叠在增强芯12周围,并引起粘合剂 在压力下均匀地渗透到增强芯12和竹片24之间的接触表面,由此可以实现牢固的接合。 此外,与竹子(如山核桃或强化木材)相比,通过使用硬度大,比重大的材料作为增强芯12,整体上提高了抗弯刚度,重量增加。 因此,与传统的竹蝙蝠相比,使用中的特点和使用感觉得到改善,棒球棒11可以用作木蝙蝠的替代品。 竹,山核桃,强化木材在资源节约方面没有任何问题,可以降低产品价格,可以降低诸如serrata等稀缺资源的消费。

    • In an A/D converter, three capacitors are connected to a comparator. The A/D converter also includes three switching circuits that each input a first reference voltage, a second reference voltage, and a third reference voltage in the three capacitors. A control circuit selects at least two of the three switching circuits during a charging period of stray capacitance of each of the capacitors. The control circuit turns on one of the switching devices in the selected switching circuits simultaneously, and during a comparing period by the comparator, selects one of the three capacitors for each comparison, and selects another capacitor in the next comparison.
    • 在A / D转换器中,三个电容连接到比较器。 A / D转换器还包括三个开关电路,每个开关电路在三个电容器中输入第一参考电压,第二参考电压和第三参考电压。 在每个电容器的寄生电容的充电期间,控制电路选择三个开关电路中的至少两个。 控制电路同时接通选择的开关电路中的一个开关器件,并且在比较器的比较期间,为每个比较选择三个电容器中的一个,并在下一个比较中选择另一个电容器。
