A semiconductor wafer (W) where circuits are formed in the area divided by streets is split into semiconductor chips having individual circuits. By interposing an adhesive sheet, whose adhesive force is lowered by stimulation, between the semiconductor wafer (W) and the support plate (13), the front side of the semiconductor wafer (W) is adhered to the support plate (13), thereby exposing the rear face (10) of the semiconductor wafer (W). The rear face (10) of the semiconductor wafer (W) with the support plate (13) is ground. After the grinding is finished, the semiconductor wafer (W) held with the rear face (10) up is diced into semiconductor chips (C). The adhesive sheet is given stimulus to lower the adhesive force and the semiconductor chips (C) are removed from the support plate (13). The semiconductor wafer and semiconductor chips are always supported by the support plate, avoiding damage and deformation.

A TOC component removing apparatus of the present invention is for removing TOC components contained in ultrapure water or pure water, including a treatment tank 2 into which the ultrapure water or the pure water is introduced, a plurality of spherical catalyst particles 3 of which surfaces are photocatalyst, a tabular translucent holding body 4 which holds the catalyst particles 3 on one surface 31a, and an ultraviolet-ray light source 5 which is arranged near the translucent holding body 4 and radiates ultraviolet rays with a wavelength of 254 nm.
摘要:
An object of the present invention is to provide an adhesive substance capable of being easily peeled off without damaging an adherend by giving stimulation thereto, a tape employing this adhesive substance, and a method for peeling off the adhesive substance. An adhesive substance, which contains a gas-generating agent for generating gas by stimulation, gas generated from said gas-generating agent being discharged to the outside of said adhesive substance so as not to foam said adhesive substance, and gas generated from said gas-generating agent peeling at least part of an adhesive surface of said adhesive substance off an adherend so as to decrease adhesive strength.

Liquid dentrifice compositions having an abrasive uniformly dispersed in aqueous medium have a low viscosity to maintain flow and stability with the lapse of time. The compositions contain 5-40% of silica or similar abrasive and an optional xanthan gum/polyacrylate binder such that they have a visocity of 20-180 poise at 25.degree.C. and a yield value of 1-60 Pa at 25.degree. C.
摘要:
According to the present invention there is provided a piezoelectric type actuator wherein a compressive force is exerted on a piezoelectric laminate, using a coil spring having a relatively small spring constant and a coned disc spring having a relatively large spring constant, the said compressive force being in the range of 4.0 to 50 in terms of the ratio of the spring constant of the coned disc spring to that of the coil spring.Under the above construction, the performance of the piezoelectric laminate is not deteriorated under any conditions during use, and the size of the piezoelectric type actuator can be reduced.
摘要:
A disk brake arrangement for a motor vehicle includes a metal backing plate shaped so as to have at each end thereof, a recessed portion. The support, rigidly attached to the motor vehicle, includes peripheral wall portions shaped to fit within a corresponding receased portion of the pad assembly. The cooperation of these portions prevents a rotation of the pad assembly during braking.
摘要:
A tire having a large number of circular dimples 62 on sidewalls thereof is disclosed. Each dimple 62 has a slope surface 66 and a bottom surface 68. The dimple 62 has a small projection 70. The small projection 70 is annular and is formed on the slope surface 66. A cross-sectional shape of the small projection 70 is substantially a rectangle. The small projection 70 is arranged so as to be concentric with the contour of the dimple 62. The surface area of the slope surface 66 having the small projection 70 is larger than the surface area of the slope surface when it is postulated that the small projection 70 does not exist thereon.
