The device for dynamically monitoring microtopography and landforms near seabed comprises a four-side frame, a connecting part, an instrument compartment and a dynamic microtopography and landforms monitoring instrument unit. The method for dynamically monitoring microtopography and landforms near seabed includes the steps of device connection, instrument debugging, device arrangement, device operation and recovery, etc. The device can be used for detecting tidal change, sequential variation of water depths at fixed point, three-dimensional seabed landform change and seabed micro-landform change in real time, thereby achieving the purpose of monitoring the change of seabed micro-landforms. The device and the method are suitable for dynamically observing landforms of seabed with various bed forms and bottom substrates, and are safe and stable. The device is convenient to install and disassemble and can be integrated with multiple marine observation instruments. The method and the device can be widely applied to detection of landforms near seabed, marine charting, marine monitoring, ocean engineering and marine scientific research.

Disclosed is a circulating-moving type horizontally-arranged air way forepoling unit. The circulating-moving type horizontally-arranged air way forepoling unit comprises a plurality of forepoling modules which are arranged in the longitudinal direction of a roadway at intervals. A frame-moving vehicle is arranged on the lower portion of each forepoling module and used for moving the last forepoling module to the forefront. Each forepoling module comprises two telescopic stand columns which are arranged on the two sides of the roadway. The bottoms of the telescopic stand columns are provided with bases. The tops of the two telescopic stand columns are connected through a top beam.

A method of forming a photolithographic mask for use in fabricating a semiconductor device is provided. The method includes forming a layer of photoresist material on a wafer and exposing the photoresist material to a light source. The photoresist material is developed, and before the wafer dries, the wafer is cleaned with one or more cleaning liquids. The cleaning liquid may be a surfactant, an acid, a dissolved gas solution (e.g., CO2, SO2, SO3, NH3, NO2, or the like), deionized water, or the like. Thereafter, the wafer is dried. The wafer may be dried, for example, by a spin dry process, a gas purge process using, for example, compressed dry air, N2, CO2, Ar, or the like, or a drying alcohol such as IPA vapor. The method of the present invention decreases the toppling of the photoresist layer pattern.

The invention provides a marine floating algae tracking and monitoring buoy, and relates to the technical field of marine equipment. According to the marine floating algae tracking and monitoring buoy, a sensing instrument is arranged on a buoy body and comprises the buoy body, a supporting frame, a reverse pushing sleeve, a piston, a first reverse pushing rod, a second reverse pushing rod, a water wheel, a floating body, a transmission rod and the like. The buoy body is connected with a reverse pushing sleeve on the supporting frame through a reverse pushing rod and a piston, a water wheel is arranged in the reverse pushing sleeve, a water wheel rotating shaft is connected with a floating body through a transmission rod, and a power generation cabin and a battery cabin are arranged in the floating body. According to the marine floating algae tracking and monitoring buoy, when the buoy swings by a large margin due to large stormy waves on the sea surface, the piston moves along the reverse pushing sleeve, seawater enters or is sprayed out of the reverse pushing sleeve, and the seawater generates counter-acting force opposite to the toppling direction on the buoy through the piston and the reverse pushing rod so as to buffer toppling of the buoy; when seawater flows in the reverse thrust sleeve, the seawater pushes the water wheel to rotate and further drives the generator to generate electricity, and electric energy is stored in the battery pack to be supplied to a sensing instrument and the like for use.

The invention relates to an intelligent AGV carrying forklift with an automatic material pushing mechanism. The intelligent AGV carrying forklift comprises a forklift main body and forks; a sliding plate slides on the front side of the forklift main body; the forks are integrally arranged on the left side and the right side of the front part of the sliding plate; a driving mechanism for driving the sliding plate to rise and fall is mounted on the forklift main body; the material pushing mechanism is integrally mounted on the upper part of the sliding plate; a material carrying plate is slidably connected with the upper sections of the two forks together; side rods are integrally arranged on the separated sides of the lower sections of the two forks; and material blocking mechanisms are mounted on the upper parts of the side rods. The material pushing mechanism can reduce the area occupied by the forks for placing goods while facilitating unloading, specifically, a material pushing plate in the material pushing mechanism is attached to the two upright rods of the forklift main body during the transportation of the goods, and the thickness of the material pushing plate is specifically 1 cm, so that the whole material pushing mechanism does not occupy a large amount of placing space.

The invention relates to the technical field of cargo transfer accessory devices, in particular to a cargo transfer auxiliary device for automatic storage retrieval. The total weight of cargoes placedon a tray can be conveniently and directly measured, and use limitation is reduced. Toppling of the cargoes with high piling height can be decreased, and use reliability is improved. The cargo transfer auxiliary device comprises a tray, a group of supporting springs, a bottom plate, a weight sensor, a group of bases, a group of supporting columns, a group of circular supporting plates, a group offixing plates, a group of fixing springs, a group of clamping plates, a group of limit plates, a group of rolling shafts, a group of rotating handles, a group of fixing rings and a group of fixing ropes, corresponding external threads and internal threads are formed in the outer walls of the circular supporting plates and the inner walls of a group of storage cavities, and the circular supportingplates are screwed on the inner walls of the storage cavities.

The invention relates to the field of table foot pads, and discloses a height-adjustable table foot pad. The height-adjustable table foot pad comprises a sleeve, wherein the middle of the upper end ofthe sleeve is downwards recessed to form a table leg fixing cavity; the middle of the lower end of the sleeve is recessed inwards to form a guiding blind hole; the lower end of the guiding blind holeextends to the periphery to form a bearing mounting cavity; a bearing is arranged in the bearing mounting cavity; an outer ring of the bearing is fixed on the inner wall of the bearing mounting cavity; an inner ring of the bearing is matched with an adjusting wheel disk; and an adjusting wheel disk mounting portion which is fixedly connected with the inner ring of the bearing is arranged on the upper portion of the adjusting wheel disk; a first screw hole is formed in the middle of the adjusting wheel disk in the axial direction; a screw which is matched with the first screw hole penetrates in the first screw hole; and a supporting table is arranged at the bottom end of the screw. The problems that when a person uses an outdoor simple table, the table cannot be placed stably if the groundis uneven and the like are solved. The height-adjustable table foot pad is further provided with a fixing hole, thus, an outdoor table can be fixed on the ground well when in environments such as a sand ground and a grassland, and thus, the stability of the outdoor table is improved.
