A novel polyolefin textile fabric knitted woven and non-woven that in one aspect of the invention is disperse dyed to a light, medium or deep solid hade. In another aspect, the textile fabrics of the present invention are manufactured using polyolefin yarns that contain variable amounts of dye acceptor additives. A fabric with more than one tone of a color is dyed in a single dye bath. The fabrics and yarn using this invention can be processed using conventional spinning, weaving, knitting, web forming machines and will dye using existing dyeing and finishing systems. This invention is of particular value in the apparel and home furnishings industry.

The invention provides a manufacturing method for an oleophilic non-stick cooker, belongs to the technical field of cookers, and solves a problem that carcinogens harmful to a human body are generatedduring a production or using process of an existing non-stick cooker. The manufacturing method for the oleophilic non-stick cooker comprises the following steps of a, preparing the cooker, namely preparing a molded cooker body; b, carrying out hard anodic oxidation treatment, namely carrying out hard anodic oxidation treatment on the surface of the cooker body in order to form a hard anodic oxidation film; c, burning, namely carrying out burning treatment on the hard anodic oxidation film on the cooker body by adopting flame with the combustion temperature of at least 1200 DEG C; d, coveringwith an oil layer, namely keeping the cooker body in a set high temperature state, and covering the surface of the hard anodic oxidation film subjected to burning treatment with edible oil; and e, cooling, namely cooling the cooker body to the room temperature. The manufacturing method for the oleophilic non-stick cooker has an advantage of good safety.

The invention discloses a real-time water sample acquiring system which comprises a towed body arranged in a sampling water area, a water sampling pipe, a water sampling device, a hydrological parameter detector and a location device, wherein the water inlet end of the water sampling pipe is arranged on the front end of the towed body; the water sampling device is communicated with the water outlet end of the water sampling pipe, and is used for acquiring a water sample through the water sampling pipe; the hydrological parameter detector is used for detecting hydrological parameters of the sampling water area; and the location device is used for obtaining geographical location information of the sampling water area. The real-time water sample acquiring system can be used for acquiring a water sample suitable for trace analysis, can continuously work when a ship is in a sailing state and can also be used for recording hydrological data and location information of the water sample in real time. The invention also provides a real-time water sample acquiring method. According to the invention, hydrological data such as temperature, salinity and depth are monitored in real time while the water sample is acquired, and a real-time and synchronous water sampling sailing track is obtained through a global positioning system and data acquisition. The system and the method meet the requirement of trace analysis sampling and dynamic continuous sampling and further provide detailed real-time sailing track and hydrological information.

The present invention relates to a portable and compact umbrella capable of being folded compactly without exposing umbrella ribs and umbrella cloth thereby being easily carried and stored. A portable and compact umbrella according to the present invention includes an extendable umbrella stick extended and retracted to change its length, wherein the extendable umbrella stick has a sheltering means provided at one side thereof and a fixing protrusion provided at the other side thereof; and a handle member having both ends communicating with each other and a receiving space defined therein, wherein the receiving space is partitioned by a cylindrical winding unit, the winding unit has an inner space formed inside thereof so that the extendable umbrella stick is retracted and received in the inner space, and the winding unit has an outer space formed outside thereof so that the sheltering means is wound around the winding unit and received in the outer space.

The invention relates to an LED (Light Emitting Diode) chip manufacturing technology, an LED chip structure and an LED chip packaging structure. According to the manufacturing technology, wolfram-molybdenum-copper alloy (WMoCu) is used as a substrate. The wolfram-molybdenum-copper alloy substrate is a good choice for a high-power LED chip heat dissipation substrate as the wolfram-molybdenum-copper alloy substrate has the thermal conductivity second only to that of a silicon carbide substrate, the cost of the wolfram-molybdenum-copper alloy substrate is far lower than that of the silicon carbide substrate, and meanwhile the wolfram-molybdenum-copper alloy substrate has the advantages of high temperature resistance, low expansion factor, high specific heat capacity, good mechanical machining property, easiness in manufacturing of mirror surfaces and the like. An LED chip in the invention sequentially comprises a wolfram-molybdenum-copper substrate layer, a U-GaN buffer layer and a N-type GaN layer from bottom to top, wherein an InGaN / GaN multiple-quantum well luminous layer and an N-electrode are arranged on the surface of the N-type GaN layer, and a P-type AlGaN layer, a P-type GaN layer, a current expanding layer and a P-electrode are also sequentially arranged above the InGaN / GaN multiple-quantum well luminous layer. Correspondingly, the LED chip has the advantages that the currents of the LED chip are vertically distributed, the substrate has high thermal conductivity and high reliability, the back surface of the luminous layer is a metal reflecting mirror, the surface has a coarsening structure, and the extraction efficiency is high.

The invention relates to a marking pen with a bent holding portion and a clamped ink tube. The marking pen comprises a penholder, the bent holding portion arranged at one end of the penholder, a front sleeve arranged at one end of the holding portion, a fiber-made writing portion penetratingly arranged in the front sleeve, a fiber-made ink feeder arranged inside the holding portion and connected with the writing portion, an ink guide component connected with the ink feeder and the clamped ink tube connected with the ink guide component in a sleeved manner. One end of the ink guide component can push away an ink sealing mechanism on the clamped ink tube, ink flows into the ink feeder through the ink guide component, and the ink feeder and the writing portion absorb ink to the benefit of writing. The main design feature of the marking pen is that the marking pen is of the structure with the bent holding portion and the clamped ink tube, the structure can guarantee that a user can write smoothly in different use occasions, has wide visual field and quickly fills the marking pen with the ink and removes the ink without touching the ink with hands, the marking pen is used repeatedly, and the purpose of reducing resource waste and cost and expenditure is achieved.
