The apparatus is equipped with vacuum laminating unit (2) furnished with a pair of heat discs (23,26) opposed to each other, at least one of these heat discs (23,26) capable of advancing forward and backward relative to the other. There is provided a laminating apparatus adapted to superimpose a film resin material on base material (8a) having at least one of its front and back surfaces furnished with unevenness on the uneven surface by the use of the vacuum laminating unit(2) to thereby form laminate (9), wherein elastic press plate (24(27)) brought into contact with the surface of the film resin material (8b) and pressing the same is disposed on the side of film resin material of the heat disc (23(26)) opposed to the film resin material. Accordingly, even when the unevenness interspace of the base material (8a) is minute, close follow of film resin layer on the base material (8a) can be attained so as to avoid any remaining of bubbles between the base material (8a) and the film resin layer.

There is provided a roller thrust bearing providing reduced differential slip, free of significant friction and wear, and providing increased longevity against flaking. The present invention provides a thrust bearing in the form of a roller thrust bearing including at least two radially arranged rows of rollers and a cage holding the rollers, the rollers including at least one roller crowned.

The invention discloses a natural mineral-based high-temperature anti-oxidation decarbonization coating. According to coating dry powder, the coating comprises the following components in percentage by weight: 15 to 35 percent of Al2O3, 35 to 55 percent of SiO2, 2 to 12 percent of Fe2O3, 2 to 10 percent of MgO, 3 to 10 percent of C, 5 to 20 percent of Na2O, 0 to 5 percent of CaO, 0 to 5 percent of K2O, and water which enables the density of the final coating slurry to be 1,100 to 1,500kg / m<3>. After the raw materials are weighed according to proportions, the water is added into the raw materials, the mixture is ground by a ball mill, the mixture is sieved by a 200-mesh sieve, and a binding agent, i.e. sodium water glass, and water are added into the mixture until the final density of slurry is adjusted to 1,100 to 1,500kg / m<3>. The coating can be directly coated onto the surface of a steel material to form a protecting layer, the oxidation burning loss of the steel material in a heating process can be obviously reduced, the surface quality of the steel material is improved, the cost is low, and the preparation process is simple.

The present invention provides a pickup method and a pickup apparatus wherein pushing up of a chip is not required and a force for holding a chip which is not picked up is not varied as pickup progresses. A method is provided for picking up a chip (13) from a fixed jig (3) to which the chip (13) is fixed. The fixed jig (3) consists of a jig base (30) having a plurality of protrusions (36) on one side and a sidewall (35) of substantially the same height as that of the protrusion (36) at the outer circumference of the one side, and an adhesion layer (31) laminated on the surface of the jig base (30) having the protrusions (36) and bonded on the upper surface of the sidewall (35). A section space (37) is formed on the surface of the jig base (30) having the protrusions by the adhesion layer (31), the protrusions (36) and the sidewall (35), and at least one through hole (38) penetrating the outside and the section space (37) is provided in the jig base (30). The pickup method comprises a step for fixing a chip, a step for deforming the adhesion layer (31) by sucking air in the section space (37) through the through hole (38), and a step for picking up the chip (13) completely from the adhesion layer (31) by sucking the chip (13) from the upper surface side of the chip (13) by means of a suction collet (70).

Provided is a water-activated sheet (1) which has a porous water-absorbing layer (3) on at least one surface thereof, the liquid absorbing capacity of the water-absorbing layer being in the range of 1-10ml / m2. In the water-activated sheet (1), an adhesive layer (4) formed by coating and then drying solid a water-based adhesive is provided on top of the water-absorbing layer of a paper material. When used in a label, the water-activated sheet resolves the problems of conventional glued labels, such as creases in the labels and seepage of the glue of the labels due to condensation, the labour required to attach labels, the residual glue on the adherend after peeling off the labels, and pollution in the water used to remove the residual glue.
