摘要:
There is disclosed an electrostatic holding apparatus in which a voltage is applied to an conductive electrode covered with an insulating dielectric layer in order to cause the insulating dielectric layer to electrostatically attract an object. The main component of the insulating dielectric layer is ceramic containing 0.1-30 wt. % of an atomic metal, and the volume resistivity of the metal-containing ceramic at 20° C. is 108-1013 &OHgr;·cm. The metallic element is Mo or W. In the electrostatic holding apparatus, since the volume resistivity of an insulating dielectric layer of an electrostatic attraction portion is decreased, a strong electrostatic force can be generated. Also, there can be maintained the capability of allowing removal of an object at the time of stopping application of voltage. Further, since neither fine cracks nor pores remain in the insulating dielectric layer after sintering, the withstand voltage is high.
摘要:
There is disclosed an electrostatic holding apparatus in which a voltage is applied to an electrode formed of a conductive layer disposed on an insulator layer and covered with an insulating dielectric layer in order to cause the insulating dielectric layer to electrostatically attract an object. The electrostatic holding apparatus is formed of a sintered body in which a thermal expansion mitigating layer is disposed between the insulating dielectric layer and the conductive layer and/or between the conductive layer and the insulator layer. The insulating dielectric layer, the conductive layer, the insulator layer, and the thermal expansion mitigating layer are superposed and press-formed in an unfired state to obtain a green body, which is then sintered to obtain the sintered body. An insulating dielectric layer, a conductive layer and an insulator layer are united while differences in coefficient of thermal expansion among these layers are minimized in order to prevent generation of inter-layer delamination, cracks, and the like, and in order to prevent generation of distortion or warping on the electrostatic attraction surface to thereby increase the electrostatic attraction force. Further, the electrostatic holding apparatus has an excellent capability of allowing removal of an object at the time of stopping application of voltage and an increased withstand voltage.

Two motor fans are driven by two 4-pole direct current motors, respectively. Rotational speed of the two motors is controlled in three stages, namely low speed, intermediate speed and high speed. Specifically, at the time of low speed operation the two motors are connected in series with four poles, at the time of intermediate speed operation the two motors are connected in parallel with three poles, and at the time of high speed operation the two motors are connected in parallel with four poles.

More specifically, provided is the microcapsule emulsion comprising an emulsion particle formed by emulsion polymerization of a total amount of 15 to 90 parts by weight of a first monofunctional alkyl (meth)acrylate ester and a first multifunctional (meth)acrylate ester in the presence of 100 parts by weight of a biological active substance; and a coated layer on the emulsion particle, the layer being formed by emulsion polymerization of a total amount of 20 to 200 parts by weight of a second monofunctional alkyl (meth)acrylate ester and a second multifunctional (meth)acrylate ester in the presence of the emulsion particle; wherein difference in carbon numbers between an alkyl group of the first monofunctional alkyl (meth)acrylate ester and an alkyl group of the second monofunctional alkyl (meth)acrylate ester is from 3 to 17.
摘要:
By inserting an insertion section provided on a lower end of a motor fan unit into a wedge shaped hole provided in a lower part of a radiator, a motor fan unit is attached to a side of the radiator to the vehicle rear. A vehicle front perpendicular surface and a vehicle rear perpendicular surface are formed on the insertion section. The vehicle front perpendicular surface contacts a perpendicular surface of the wedge shaped hole, while the vehicle rear perpendicular surface contacts a lower end of an inclined surface of the wedge shaped hole. These surfaces will be in contact with one another even if the radiator stretches in the vertical direction due to evacuation and irrigation so that the insertion section slides upwards. As a result, it is possible to prevent rattling of the motor fan unit.

摘要:
A temporarily labelled image data generating circuit is composed of an initial label memory, which stores the initial temporary label values of pixels that are connected within the line being scanned, and a run length counter, which counts the number of pixels of the connected pixels, and finally labelled image data is generated following the generation of temporarily labelled image data and temporary label table data, which indicate the conversion relation for the modification of the temporary labels, using the initial label memory and run length counter, which improves the processing speed by reducing the number of times the memory is accessed and reduces the storage capacity of the working memory.
