The invention provides a lateral double-diffused metal oxide semiconductor (LDMOS). The pre-metal dielectric layer (PMD) of the LDMOS is a silicon rich content material. Additionally, the inter-layer dielectric layer (ILD), inter-metal dielectric layer (IMD), or protective layer of the LDMOS may be formed of a silicon rich content material.

A windows-breaking emergency escape device including a main body, a hammer and a supplementary power apparatus, wherein the hammer and the supplementary power apparatus are installed on the main body. The front end of the hammer extrudes from the surface of the main body. The supplementary power apparatus will reserve enough power in advance to lessen an operating force and to release the reserved power to drive the hammer to break the car window when a car accident happened. Moreover, the main body of the device of the present invention includes a groove containing a cutter.

The improved plumb-bob is mainly consisted of a body section, a point section, and a fixing element, wherein a connecting means is arranged at the top of the body section by which it may be connected to a suspending cord, and the point section is a cylinder with a flange arranged at the shank, and the point section is provided at least at one end with a conical-pointed part, and the fixing element is bored from the low end to the upper end forming an upper portion and a lower portion. The upper portion is of larger diameter and the lower portion is of reduced diameter but is larger than that of the point section, thus forming an angular shoulder against which the fringe abuts when the parts are assembled to enable the conical-pointed part to project outwardly under the fixing element. The fixing element can hold and fix the point section in a proper position between the body and the fixing element. The invention may simplify the structure of the expandable point section such that not only the manufacturing cost of the point section is reduced, but also many unnecessary compatible constraints may be removed, that is, when the point section is damaged and no spared point section for replacement, a metal nail, such as iron nail, steel nail, etc., with similar diameter can be applied as a substitute.
