Disclosed is a diamond tool having a metal plate inserted therein. Between abrasive layers containing diamond particles is inserted a ferrous or non-ferrous metal plate having a wear resistance lower than that of the abrasive layers such that a concave groove is spontaneously formed during a cutting process, thereby reducing the contact load with a workpiece to thereby avoid vibration (wobbling) of a shank, and providing a discharge path for smoothly removing cutting chips and the cooling water. In addition, the content of abrasives and the wear resistance of bonding material are uniformly constituted so that the shrinkage rate does not need to be considered during sintering and the manufacturing process can be simplified, thereby reducing the manufacturing cost and improving the productivity therefor. Furthermore, the area of the metal plate can be controlled, thereby enabling an easy design conforming to the working conditions with a workpiece.

A backlight assembly and a liquid crystal display device can discharge heat from the lamp unit to the outside or effectively dissipate the heat. The backlight assembly of the present invention includes a lamp unit, a receiving member for receiving the lamp unit, a first heat dissipation member disposed below the receiving member, and a second heat dissipation for wrapping around a lateral side of the receiving member and the first heat dissipation member. The lamp unit is disposed on an area corresponding to the lateral side of the receiving member. In one embodiment, the first heat dissipation member is a flat plate made of graphite and disposed on an outer side of the bottom of the receiving member. The second heat dissipation member is metal with good thermal conductivity in close contact with the first heat dissipation member and the lateral side of the receiving member where the lamp unit is disposed. Thus, the heat discharged from the lamp unit can be distributed uniformly over the entire area of the receiving member. In addition, the lateral side of the receiving member where the lamp unit is disposed can be replaced with the second heat dissipation member.

The invention relates to a method for manufacturing dielectric ceramic powder and a multilayer ceramic capacitor using the ceramic powder. According to the invention, BaCO3 powder is dispersed into a solution of solvent and dispersant to prepare BaCO3 slurry and then the resultant BaCO3 slurry is wet-milled. Also, TiO2 powder slurry is mixed into the wet-milled BaCO3 slurry to form mixed slurry and then the mixed slurry is dried into mixed powder. Finally, the dried mixed powder is calcined to produce BaTiO3 powder.

Disclosed are methods and systems for determining a topography of a lithographic optical element and/or a holder of a lithographic optical element. In one embodiment, the method includes directing electromagnetic radiation towards a lithographic optical element, where the electromagnetic radiation comprises electromagnetic radiation in a first predetermined wavelength range and electromagnetic radiation in a second predetermined wavelength range. The method further includes using the lithographic optical element to adsorb the electromagnetic radiation in the first predetermined wavelength range, and to reflect at least a portion of the electromagnetic radiation in the second predetermined wavelength range towards a substrate comprising a photosensitive layer, thereby exposing the photosensitive layer to form an exposed photosensitive layer. The method still further includes performing an evaluation of the exposed photosensitive layer and, based on the evaluation, determining a topography of the lithographic optical element.

A method for fabricating high efficiency CIGS solar cells including the deposition of Ga concentrations (Ga/(Ga+In)=0.25−0.66) from sputtering targets containing Ga concentrations between about 25 atomic % and about 66 atomic %. Further, the method includes a high temperature selenization process integrated with a high temperature anneal process that results in high efficiency.
摘要:
A method of making a finely textured molded article is disclosed. The method utilizes properties of the compound being molded, such as impact toughness and melt flow index. Poly(vinyl halide), particularly polyvinyl chloride), articles can be custom-injection-molded using the method, in order to simulate the appearance of original metal, glass, or wood articles. Consumer, transportation, building construction, and other industries can benefit from durable plastic articles that simulate the more fragile articles.

Slider including at least one pad including shape memory alloy layer with titanium oxide contact layer. When slider contacts disk surface, pad(s) undergoes solid-to-solid phase change from the first to second phase, absorbing energy and possibly deforming. When contact is removed, the pad recovers its shape as shape metal alloy undergoes a reverse solid-to-solid phase change. A shape memory alloy of elements refers to any molecular or crystalline combination which is a solid possessing the shape memory property of at least two solid phases in the operating and storage conditions of a hard disk drive. A head gimbal assembly including the slider, head stack assembly including at least one head gimbal assembly, and the hard disk drive including the head stack assembly. Manufacturing methods for the slider, the head gimbal assembly, the head stack assembly, and the hard disk drive, as well as the products of these manufacturing processes.

In a camera module having an array lens, a first lens group has at least two lenses. A second lens group has a plurality of lenses corresponding to the lenses of the first lens group, the second lens group stacked below the first lens group and interposing a spacer part therebetween. An image sensor has an imaging region where light passing through the first and second lens groups is imaged. Also, a shielding unit shields portions excluding apertures of the lenses of the first and second lens groups, the shielding unit disposed between the first and second lens groups. The camera module has a lower optical system along an optical axis for smaller size, keeps light refracted from an adjacent lens from affecting an image, blocks leakage of light for imaging and increases definition of the image through signal processing.

摘要:
A disk drive that has a plurality of heads coupled to one or more disks. The heads have air bearing surfaces that compensate for a radial crown and a radial camber of an adjacent disk to maintain a flying height at a relatively constant level across the disk surface. By way of example, the air bearing surfaces may have crown and camber sensitivities that are opposite in sign from the crown and camber sensitivities created by the disk. The opposite sensitivities offset the sensitivities of the disk to maintain an essentially constant flying height as the head moves across the surface of a disk.
