An optical-pickup slider is characterized in that a light-transmitting-property substrate is bonded to a surface of a layer having a tapered through hole, on which surface a larger opening of the tapered through hole exists. Thereby, it is possible to prevent the layer having an aperture from being destroyed. A method of manufacturing the optical-pickup slider comprises the steps of a) making a tapered through hole in a layer layered on a first substrate and having a thickness smaller than that of the first substrate; and, after bonding a light-transmitting-property substrate to a surface of the layer, removing the first substrate so as to expose an aperture at a tip of the tapered through hole.

The present invention relates to a floatable vessel lift comprising: at least two pontoon chambers, where each of the at least two pontoon chambers includes a top housing and a base. The pontoon's top housing has an arcuate longitudinal surface and the base side is substantially flat. Support members horizontally join the at least two pontoon chambers to support a vessel during the lifting process. A user varies the submersion of the vessel lift during use by using a single air infusion device that introduces an air flow into the at least two pontoon chambers simultaneously.

The invention belongs to the field of treatment of dung in large-scale animal farms and in particular relates to a resource comprehensive utilization device used for treating animal dung. The device comprises a biogas generating unit, a septic unit and a separation tank, wherein the biogas generating unit comprises at least a biogas tank, the upper sides of the biogas tanks are covered by a transparent plastic film, gas collection and storage units covering fermented matters in the tanks are also arranged in the biogas tanks, and the fermentation residues in the biogas tanks are discharged into the septic unit; the septic unit comprises at least a septic tank, and the liquid in the septic tank is discharged into a discharge unit; the separation tank is used for carrying out solid-liquid separation on the liquid flowing into the separation tank, and an outlet is formed in the wall of the separation tank. The device has a simple structure, is low in manufacturing cost, is convenient to popularize and use in vast regions in the countryside, simultaneously can be normally used in winter, and ensures the yield of biogas.

The invention provides a method for manufacturing a patterned magnetic recording medium including a step of completely removing an etching resist on a magnetic layer 3, which is used for etching the magnetic layer 3, without deteriorating magnetic characteristics of the magnetic layer 3. The step of removing the etching resist used for etching the magnetic layer 3 includes the steps of irradiating the etching resist on the magnetic layer 3 or the first protective layer 4 with an excimer VUV laser under a reduced pressure and immersing the resist coating 5 remaining on the magnetic layer 3 or the first protective layer 4 into a resist removing agent solution to wash off the resist coating 5.

A plant-culturing tool comprising a planting container for accommodating a plant, and a water storage container that can accommodate the planting container in the interior of the water storage container and that can store water, a guide mechanism in which the planting container makes sliding contact with the water storage container and is guided along a floating or sinking direction thereof. The guide mechanism is composed of a long guide surface having a long sliding portion, and a short guide surface having a short sliding portion that protrudes against the long guide surface, with the two guide surfaces making slide contact each other.

The invention discloses a preparation method for noble / noble composite wire materials, and noble / cheap composite wire materials, wherein the preparation method is simple to operate, and the composite wire materials are controllable in thickness of a composite layer, clean in limiting surface, good in limiting surface bonding and easy to process subsequently. The preparation process includes that an outer layer of metal is machined to a round pipe by ingot casting, extruding and drawing, and wall thickness is designed according to demand of product design. The noble metal round pipe is placed in a water-cooling mold, core material metal is placed in a vacuum induction melting furnace to be melted, core material molten metal is poured into the water-cooling mode to be fast set, the water-cooling mold is adjusted, and cooling speed of the core material molten metal is changed so as to produce a composite bar of clad materials and a core material binding layer (a transition layer). The composite bar is machined through rotary swaging, and is carried out with heat treatment and wire drawing in the middle process to meet product size requirements of customers. The composite wire materials are wrapped evenly by outer layer metal, and the wrapping layer and the core materials are good in cooperated transformation. The wrapping materials and the core materials are closely combined. The wrapping materials can be used for advanced packing of an integrated circuit and the like, and part of wrapping materials or all wrapping materials can replace the noble metallic bond composite wire materials.

The invention relates to a guide float valve, which comprises: an ellipses valve cover whose short axle has spindle guide plate bended at two sides, and long axle has one ellipses liquid plate at one end, wherein the lower end of liquid plate has one valve stop pin; another end of said long axle has a vertical bended valve leg; the lower end of said leg has another valve stop pin; the valve leg has a ventilate hole; the valve cover has a guide small float valve; the liquid plate can completely block the airflow reversed to the liquid, and via using liquid plate and guide small float valve to guide the gas, the gas will be guided out, and the convective overshooting between valves can be avoided, to reduce the liquid gradient and reduce the energy consumption.

The invention discloses a clamping type raise boring machine. The clamping type raise boring machine includes a base support, a telescopic mechanism, a drilling rod and a drilling bit. A telescopic groove and a connecting channel are respectively disposed at upper and lower sides of an inner ring sleeve, one end of the T-shaped telescopic rod sequentially passes through a telescopic groove and theconnecting channel and is then fixed on an outer side surface of a clamping plate, the other end of the T-shaped telescopic rod is limited in the telescopic groove, upper and lower ends of a connecting shaft are respectively inserted into T-shaped insertion clamping grooves of the clamping plate through T-shaped insertion clamping bars, so an outer ring sleeve and the inner ring sleeve can move up and down along the T-shaped telescopic rod. The clamping type raise boring machine is advantaged in that floating is more stable.
