An active high-safety air bag for helicopter features that several air bags and several gas generators communicated to said air bags (one to one) via inflating tube are arranged in the recesses on the bottom of helicopter body and a controller close to the driver' s seat is used to control said gas generators.

The present disclosure relates generally to the manufacturing of semiconductor devices. In one example, a method for forming a portion of a semiconductor device includes forming a photo sensitive layer over a substrate, developing the photo sensitive layer to expose a portion of the substrate and to create a seed layer from at least a portion of the photo sensitive layer remaining after the developing, forming an etch stop layer only on the seed layer, and etching the substrate using the etch stop layer as a mask.

The invention relates to a side airbag device (1) for vehicles, comprising at least a first and a second material layer (10.1, 10.2) for forming an airbag (10) having at least one chamber (12) that can be inflated by means of gas. In the inflated state of the airbag (10), the first material layer (11.1) extends in a vehicle longitudinal direction (x direction) and the second material layer (11.2) lies opposite the first material layer (11.1). The first and second material layers (11.1, 11.2) are connected to each other along at least a first edge section (11.11, 11.21). According to the invention, in the inflated state of the airbag (10), the first and second material layers (11.1, 11.2) each have a first edge section (11.11, 11.21) extending in a vehicle vertical direction (z direction) and a second edge section (11.12, 11.22) extending in the plane spanned by the vehicle longitudinal direction (x direction) and the vehicle transverse direction (y direction), the first edge sections (11.11, 11.21) of the first and second material layers (11.1, 11.2) are connected by means of a first seam (13) that at least partially bounds the chamber (12), and a second seam (14) is provided, which is formed by the second edge sections (11.12, 11.22) and bounds the chamber (12) additionally to the first seam (13) and extends transversely to the first seam (13).

The invention discloses lubricating grease used for an automobile hub bearing and a preparation method thereof. The lubricating grease used for an automobile hub bearing comprises the following components by weight: 70-90% of base oil; 5-20% of a soap thickener; 1-5% of an extreme pressure antiwear agent; and 5-15% of a polymer composed of one or several of an ethylene-propylene copolymer, polymethacrylate, and polyisobutylene; and 1-3% of an antioxidant. With a scientific formula and simple preparation technology, the lubricating grease of the invention overcomes many disadvantages existing in prior art, and realizes the advantages of excellent high temperature performance, extreme pressure performance, adhesion performance, shearing resistance and water resistance. The lubricating grease provided in the invention is suitable for lubricating automobile hub bearings, especially suitable for long time lubrication of high temperature, high speed and high load heavy truck and coach hub bearings.

The invention discloses a die overturning transformation tool for resistors. The tool comprises a bottom die, a middle die, a cover plate, a first tooth comb and a second tooth comb. A grid area and a non-grid area are arranged on the upper surface of each of the bottom die and the middle die, wherein a gap exists between every two adjacent grids, and the resistors can pass through the gaps between the grids of the middle die. The gaps between the grids of the bottom die are of a structure with the apertures gradually reduced from top to bottom. The bottom die can be completely covered with the middle die, and the gaps of the grids of the middle die correspond to the gaps of the grids of the bottom die. The cover plate is provided with a plate face and a handle, wherein the area of the plate face at least can cover the grid area of the bottom die and the grid area of the middle die. Each of the first tooth comb and the second tooth comb is provided with comb teeth and a tooth comb handle, wherein the front ends of the comb teeth are provided with tooth tops, and a tooth gap exists between every two adjacent comb teeth. According to the die overturning transformation tool for the resistors, batched die overturning transformation of the resistors is achieved, the working efficiency is improved, and the damage rate in the die overturning transformation process of the resistors is reduced.

The invention relates to a multifunctional protective clothing. The protective clothing has a structure of seven layers, wherein the sequence from inside to outside is a functionality fabric layer which is used as a close fitting skin underwear and has a moisture absorption and perspiration function; wool or a fleece layer; a soft shell layer or a hard shell layer; an ultralight quantization down feather layer; a special type flame retardance fabric layer; a radiation protection layer; a medical nanometer protection material layer. A charging source, a GPS position indicator, an interphone and a wireless network module are arranged on an upper outer garment, and users can keep in touch with other users nearby. The multifunctional protective clothing can provide enough protection for emergency disposal personnel in an emergency and guarantee the safety of personnel.

The invention provides an MEMS (micro electro mechanical system) microphone chip and a manufacture method thereof. The MEMS microphone chip comprises a substrate and a parallel plate capacitor arranged on the substrate, wherein one side of the parallel plate capacitor is opposite to the substrate; and the outer part of the other side of the parallel plate capacitor is provided with a protective device for protecting the main body structure of the MEMS microphone chip. In the MEMS microphone chip, a vibrating diaphragm is provided with the protective device so as to separate structures, such as tender vibrating diaphragms and the like in the parallel plate capacitor from the outer space of the MEMS microphone chip, so that the MEMS microphone chip can be prevented from being polluted in the cutting process so as to effectively improve manufacture process efficiency, lower production cost and improve production yield; and in addition, the chip can be fully protected in the subsequent installing and using process of the MEMS microphone chip.
