摘要:
A coating apparatus (2) includes a work table (20) having a plurality of blowing holes (201) for suspending a substrate (200) thereabove, a coating unit (22) having a photoresist coating nozzle (222) and a supplying device (224) for photoresist material. The photoresist coating nozzle is disposed above the work table, and the supplying device connects to the coating nozzle for supplying photoresist thereto. In operation, the substrate to be coated is continuously suspended in the gas just above but not in contact with the work table. Therefore, accumulation of static electricity and/or foreign particles on the substrate can be avoided. Gas emitting from the blowing holes can remove foreign particles from the surface of the work table and the backside of the work table.

The invention is one optical measurement based three-dimension (3D) topology detection equipment. It is conducted to improve the reconstruction accuracy and achieve the objective of acquiring both macro and micro texture morphology. The invention provides a method to acquire both macro and micro texture morphology of pavement at the same time, which can be used to measure characteristics of a surface topology. The proposed method requires six light sources and is improved by adopting low-rank decomposition method, control point-based interpolation surface algorithm to solve normal vector, which can reduce the measurement error and improve the test accuracy. Six highlighting concentrated parallel light sources (HSL-58-105-W) are required in the method. The slant angles of six light sources are all 45° and the tilt angle of six light sources is 0°, 60°, 120°, 180°, 240°, 300°, respectively. The camera is SONY DSC HX-300 digital single lens reflex (SLR) and six photos of pavement texture morphology are taken by the camera under different illumination. Compared with traditional texture morphology test method, the acquisition method in the invention can obviously increase the test precision of texture morphology and acquire macro and micro texture morphology at the same time fast, accurately and repeatedly.

Disclosed is a system for engaging safeties on an elevator car. The system comprising a contact surface in a hoistway and a safety tripping lever pivotally mounted on an elevator car. Upon contact by the lever with the contact surface, the safeties engage, with the contact surface preventing the safeties from disengaging until the car comes to a stop. A feature of the system for engaging safeties on an elevator car is the ability of a portion of the safety tripping lever to retract away from the contact surface upon movement of the elevator car in a direction opposite of the car's braking direction, wherein the retraction of the lever facilitates the disengagement of the safeties.

Elevator compensation ropes are attached to the elevator cab frame by means of a wedge block which is mounted on a lower portion of the frame. The wedge block has a plurality of separate wedge-shaped passages thereon through which each of the compensation ropes passes upwardly. The ropes are looped over V-shaped inserts and then passed downwardly through the passages. The inserts are dropped into respective ones of the passages so as to wedge the ropes against the wedge block. The counterweight is connected to the compensation ropes with a plurality of rope deflectors which guide the ropes from a fanned out series of thimble rods to a closely spaced parallel rope array which extends from the counterweight into the hoistway pit.

A data transmission system and method is disclosed, which is applicable to a network system having a server end and a plurality of user ends that connect with the server end and with one another. By categorizing the user ends into a high speed group and a low speed group based on a first speed standard, detecting maximum data transmission speeds between the user ends, and selecting appropriate user ends categorized into the high speed group to process data transmission with the user ends in the low speed group, the data transmission system and method of the present invention provides a technique which can take the full advantage of the redundancy of data transmission speed of user ends and increase the efficiency of transmitting data speed.

An apparatus comprising an encoder, a packet generator, a disc loader, and a rebuild circuit. The encoder may be configured to generate a format data stream in response to an input signal. The packet generator may be configured to generate special packets from extracts of the format data stream. The disc loader may be configured to write the special packets on a disc. The rebuild circuit may be configured to (i) rebuild one or more navigation files and a file system with the special packets and (ii) write the one or more navigation files and the file system to the disc.

A clip is bolted to the wall at points along the rail to hold the rail on the wall. Each clip includes a rigid retainer and a curved springy spacer. The clip is bolted to the wall to force the spacer against the rail, to force the rail against the wall. The spacer is slightly flattened to hold the rail in place, but allows the rail to slide in the retainer, along the wall, as the wall settles, thus preventing compression forces in the rail between the clips.

Polyurethane composition based on a certain polyether and polyester prepolymer reaction mixture, wherein the composition is utilized in manufacturing chemical mechanical polishing/planarizing (CMP) pads. The CMP pads have low rebound and can dissipate irregular energy as well as stabilize polishing to yield improved uniformity and less dishing of the substrate.
