Abstract

A miniature portable equipment in the present invention comprising a packing comprising a butyl rubber having a crosslinking structure composed of carbon to carbon bonds of the formula: <CHEM>

Description

technical field [0001] The invention relates to a miniature portable device with a designated sealing pad, especially a watch with a designated sealing pad or a miniature portable information device terminal with a designated sealing pad. More specifically, the present invention relates to a long-life watch utilizing, for example, a long-life battery or a solar cell that converts light energy into electricity; or a mechanical watch that does not require a battery, or that can be cleaned, for example, by ultrasonic cleaner to clean the watch. These watches have excellent long-term water resistance because of the packing that prevents the infiltration of water and steam from the outside and prevents the infiltration of human sweat and greasy substances, etc. Background technique [0002] A tiny portable device, a watch being a prime example, needs to be waterproof because we wear it every day. [0003] For example, try Figure 4 , the figure shows a partial cross-section of ...
