Abstract: PURPOSE: A method for forming a photoresist pattern is to prevent the notching produced when a photoresist pattern is formed on a metallic film having a high reflectance. CONSTITUTION: A dielectric film is formed on a substrate, the dielectric film having a thickness corresponding to even times of a value of (a wavelength of an exposing light) times (4 times a refractive index of the dielectric). A photoresist pattern is applied on the dielectric film, and is exposed to light. The dielectric film is made of a silicon oxide film having a refractive index of above 2.0. After forming the photoresist pattern, the silicon oxide film is formed to have a thickness of 1090 angstrom, and the photoresist pattern is exposed by the light of 4360 angstrom wavelength. Since the thick thickness of the oxide film serves as a barrier when etching the metallic film, the thinnest thickness thereof is selected.

Title: Fastening element
Inventor: BEAUVAIS SIMON
Filed: 2021-06-16
Abstract: The application relates to a fastening element, such as a stud, nail or pin, comprising a shank (220), which defines a driving-in direction, the shank (220) having a front end, facing in the driving-in direction, and a rear end, facing counter to the driving-in direction, the shank (220) having at its periphery a profile ridge (140) that is inclined in relation to the driving-in direction at an acute angle. According to one aspect, the profile ridge (140) has a front flank (141), facing in the fastening direction, and a rear flank (142), facing counter to the fastening direction (30), the front flank (141) having a greater area content than the rear flank (142). According to a further aspect, the fastening element has a tip region (270), which has a convex portion. (Figure 5)

Title: Float-swing hydraulic support
Inventor: LI BINGWEN
IPC: E21D15/00
Filed: 2015-11-30
Abstract: Abstract A float-swing hydraulic support, comprising a top beam, a shield beam, an elevating frame, a base, an adjusting jack, two float hydraulic columns, a base raising unit, an advancing unit, a face guard unit, a telescopic beam unit, a hydraulic control valve block, and a valve block support. The two float hydraulic columns are arranged in parallel between the top beam and the base, with the upper ends of the columns being ball-hinged to the top beam and the lower ends of the columns being ball-hinged to the base; the telescopic beam unit is disposed in the front end of the top beam, and the face guard unit is hinged to the telescopic beam unit; the upper end of the shield beam is hinged to the top beam, and the lower end of the shield beam is hinged to the upper end of the elevating frame; the upper end of the adjusting jack is hinged to the shield beam, and the lower end of the adjusting jack is hinged to the base; the front end and the rear end of the advancing unit are hinged to a scraper conveyor and the base respectively. The float-swing hydraulic support is applicable to underground working faces of fully mechanized coal mining in coal mines; the float-swing hydraulic support realizes modular design, standard design, and series design, and has advantages including large working area, large ventilation area, high safety, high reliability, and high stability, etc., and has high practicability. 2628516v1
