Abstract:
Provided is a driver's airbag module assembly structure including: an inflator for generating gas by igniting an exploder; an airbag inflated toward a driver by the gas generated by the inflator; a cage covering the inflator; a mounting plate for accommodating the inflator, the airbag, and the cage to be fixed in a cover member disposed at a handle; and a horn plate installed between the mounting plate and a steering wheel, characterized in that the mounting plate has a plurality of fixing clips formed at its outer surface, the cover member has a plurality of coupling holes coupled with the fixing clips, the horn plate is provided with a bracket having an angled tip and a fastening hole, and the steering wheel is provided with a groove having an angled step corresponding to the bracket of the horn plate.Therefore, hooks of a mounting plate push flexible pieces formed at coupling holes of a cover to allow the mounting plate and the cover to be easily coupled with each other. In addition, since the hooks are closely inserted into lower horizontal holes, movement of the hooks can be reduced. Further, the hooks do not separate from the coupling holes when the airbag is deployed.
Abstract:
A fusing device includes a rotatable pressing roller, a fusing belt to rotate by a rotational force transmitted from the rotatable pressing roller, a nip forming member to contact an inner surface of the fusing belt to form a nip on a contact area between the rotatable pressing roller and the fusing belt, a heating member formed in approximately an internal central portion of the fusing belt to heat the nip forming member and the fusing belt, an inner support member formed within the fusing belt to press a nip part of the nip forming member toward the rotatable pressing roller, and an outer support member formed outside the fusing belt, and both ends of the outer support member being engaged with the inner support member to thereby reinforce the strength of the inner support member and form a path for radiation heat to disperse. The support unit includes an inner support member placed within the belt unit, and an outer support member placed outside the belt unit, both ends of the outer support member being engaged with the inner support member to reinforce the strength of the inner support member and to form a path for a radiation heat to disperse.
Abstract:
A process chamber of a dry etching facility for manufacturing semiconductor devices uniformly forms the ion density of plasma over a wafer, and reduces the volume of the process chamber by installing a plurality of discharge openings in an electrode housing which supports the electrode plate of a lower electrode. The lower electrode is a discharge electrode which is constructed such that a plurality of discharge openings are symmetrically provided in the side wall of the electrode housing supporting the electrode plate on which a wafer is mounted, and the discharge openings form a discharge passage which is connected to a discharge pipe at a pipe connection opening.
Abstract:
A phase-change memory device comprises a first insulating layer on a substrate and a through hole formed in the first insulating layer. A first phase-change material layer is positioned along lower sidewalls and a lower face of the through hole. A second insulating layer is laterally surrounded by the first phase-change material layer. A second phase-change material layer is positioned along upper sidewalls of the through hole and in contact with upper surfaces of the first phase-change material layer and the second insulating layer.

The ESD protection device includes a metal-oxide semiconductor (MOS) transistor, including a source area having a surface on which a first silicide is formed, the source area including a source connecting area including a first connecting portion formed on the first silicide, and a source extension area, a gate arranged in parallel with the source area, and a drain area arranged in parallel with the source area and the gate, the drain area having a surface on which a second silicide is formed, the drain area including a drain connecting area formed opposite the source extension area, the drain connecting area including second connection portion formed on the second silicide, and a drain extension area formed opposite the source connecting area.
Abstract:
A backlight assembly, a display device including the backlight assembly and a control method thereof are provided. The backlight assembly includes: a DC converter which converts input alternating current (AC) power into direct current (DC) power at various levels; a light source unit which has at least one point light source; and a power supply unit which receives the DC power output by the DC converter, converts the DC power into output power having a preset reference current level and supplies the output power to the light source unit.
Abstract:
An audio playback time estimating apparatus and method. The apparatus includes a sampling unit to sample a plurality of sample frames of audio data from audio data including an ID3 tag and a plurality of frames using a quasi-random sampling method, an average-bit-rate-calculation unit to calculate an average bit rate of the audio data based on bit rates obtained from the plurality of sample frames, and a playback-time-calculation unit to estimate the playback time of the audio data based on the average bit rate.
Abstract:
The present invention provides a method for manufacturing the imide-substituted polymer comprising the following four consecutive steps of (i) the copolymerization step of copolymerizing aromatic vinyl monomers and unsaturated dicarboxylic anhydride monomers, (ii) the separation step of removing the unreacted monomers and solvents from the abovementioned copolymerized solution continuously supplied to the separator, (iii) the imide substitution step of reacting unsaturated dicarboxylic anhydride units in said copolymers with primary amines, and (iv) the devolatilization step of removing low-molecular-weight volatiles from the polymer solution. The imide-substituted polymer manufactured according to the methods in the present invention has greatly improved the heat resistance and the productivity as the content of aromatic vinyl homopolymers is reduced significantly and the reaction time is shortened extensively.
