An apparatus including an elongate body having a lumen extending therethrough and a steering wire associated with the distal portion of the elongate body.

A manufacturing method and a bonding apparatus for a liquid crystal display device is provided for that makes it possible to expel remaining bubbles from a liquid crystal and to bond an array substrate and a color filter substrate while maintaining their positional relationship. In a step for bonding an array substrate with a liquid crystal applied thereto and a color filter substrate, vacuum holding of only a central retaining region of an upper vacuum chuck of the bonding apparatus is stopped. This causes the central portion of the color filter substrate to come in contact with the array substrate due to its own weight. The contact region is pressed by a holder to secure the positional relationship between the array substrate and the color filter substrate. Thereafter, with the elapse of time, the upper vacuum chuck increases the retaining region for which a vacuum retaining operation is stopped so as to expand the area of contact between the array substrate and the color filter substrate. As a result, bubbles in the liquid crystal are expelled externally.

A thermal-pressure relief device, which has an adapter (20) threaded into the wall of a pressure vessel. The adapter contains an orifice (22) therethrough in line with a recessed cavity (32) which includes a raised stem (34). A blow out member (30) rests on the stem and overlaps the orifice to obstruct communication with the fluid inside the vessel. The blow out member is attached within the cavity by brazing with a filler metal in the form of a temperature responsive amalgam (38), preferably a eutectic alloy. When ambient temperatures are elevated above the melting point of the amalgam the blow out member is released freeing the orifice relieving the pressure within the vessel preventing a sudden structural failure. Optionally a protective cover in the form of a cap (42) with an impact surface (40) contains the blow out member when it separates from the adapter and a number of vents (48) diffuse the fluid from the pressure vessel in a safe direction. Another option for the protective cover is a tube (54) attached to the adapter with fastening means such that when the blow out member is released the conduit provides a safe structurally sound flow path permitting the pressurized fluid to be directed into a safe zone away from the thermal-pressure relief device.

The invention discloses a rapid investment casting method based on stereolithography (SL). A wax mould in investment casting is replaced with a resin prototype (1) produced by applying a 3D printing technology, the resin prototype (1) is of a thin-walled honeycomb structure, an ingate (2) is arranged on the resin prototype (1), a gating system adopts a conventional wax gating system (3), a groove (4) is formed in the wax gating system (3), the ingate (2) is inserted into the groove (4) to be bonded and fixed during tree casting, a wax rod (5) is arranged on the resin prototype (1), and vent holes are formed after shell making. The rapid investment casting method reduces the casting cost, reduces the production cycle, and avoids the cracking phenomenon of a shell in the process of roasting.

External electrodes, electrically connected to exposed portions of internal electrodes, are arranged on end surfaces of a ceramic main body of a laminated ceramic capacitor. Alloy layers of a metal contained in internal electrodes, and a metal contained in external electrodes, are arranged at the boundaries between external electrodes, and the ceramic main body and internal electrodes. Plating layers are provided on surfaces of external electrodes. A ceramic electronic component having a reduced ESR is thus provided.

In a flat panel display panel and a method of manufacturing the same, the flat panel display panel may be constructed with a first substrate on which a plurality of pixels are formed; a second substrate disposed so as to face a surface of the first substrate on which the plurality of pixels are formed; a first sealing member disposed between the first and second substrates for sealing them; a first bank formed on the first substrate; a second bank formed on the second substrate and disposed facing the first bank; and a second sealing member disposed between the first and second banks.

The structure of comb tooth type silicon processing micromachinery accelerometer includes the tooth comb formed by means of body processing, sensing quality element formed from several groups of moving teeth and folded beam group fixed tooth biased fixed tooth and substrate, and its circuit includes the portions of microcapacitor detection and force feedback servocircuit, etc. Said invention can develope the face-processed comb tooth structure into body-processed comb tooth sturcture by means of fixed tooth biased structure, and can increase detection and thrust capacitance so as to greatly raise its resolution and accuracy. Besides, in its preamplifier low input impedance circuit is used and in closed loop feedback thrust the differential D.C. voltage mode is used, so that it can make instrument possess high accuracy.

The invention discloses a fingerprint module, a display device and a mobile terminal. The fingerprint module comprises a supporting piece and a fingerprint chip, wherein the supporting piece comprises a main body and an extending piece extending from the peripheral side of the main body; the main body is provided with an accommodating groove; the extending direction of the extending piece is vertical to the opening direction of the accommodating groove; the extending piece is used for being attached to the back surface of a display screen; the fingerprint chip is fixed in the accommodating groove; and the fingerprint chip is parallel with the extending piece. Through extending the extending piece from the peripheral side of the main body of the supporting piece and enabling the extending piece to be attached to the back surface of the display screen, the attaching area between the fingerprint module and the display screen can be expanded; as the extending piece is parallel with the fingerprint chip, the parallelism between the fingerprint chip of the fingerprint module and the display screen is further ensured; the fingerprint chip sensing signal transmitting and receiving accuracy is improved, the fingerprint acquisition efficiency is enhanced, and the user experience is improved.

The invention discloses an automatic control device of drop transfusion system, which consists of lye storage and float in the lye storage, wherein the liquid-in needle (1) with liquid-in opening (2) and vertical convex area (3) toward intracavity with liquid-out opening (4); the float contains cylindrical floater (5) and soft elastomer sealer (8). There is longitudinal gap between sealer (8) and vertical convex area (3) that matches each other. The invention provides a precise and reliable sealed transfusion system with automatic closing system effectively, which can be applied in the medical treatment domain widely.
