PURPOSE:To prevent capacity deterioration and increase life by forming a lead- acid battery with a cathode substrate or lead-antimony alloy and an anode substrate of lead-calcium alloy. CONSTITUTION:A lead-acid battery is formed with a cathode substrate of lead- antimony alloy and an anode substrate of lead-calcium alloy. Short life in deep charge-discharge caused by a lead-calcium alloy plate is ...

A tire casing includes a puncture-sealing layer (2) on the inside surface thereof, the puncture-sealing layer (2) being made of rubberised interwoven flexible cords. It is due to the flexibility of the interwoven cords and the elasticity of the rubber, once a sharp object pierces the tire casing (1) and the puncture-sealing layer (2), the rubberized cords will work to tightly bind the sharp object...
