摘要:
A rotating member supporting apparatus has a rotating shaft which is inserted to a bore formed in a support member. A rolling bearing is interposed between the rotating shaft and support member and rotatably supports the rotating shaft. The bearing includes an inner and outer rings which have resistance to heat and corrosion, and a plurality of rolling elements rollably arranged between the inner and outer rings. The rolling elements are formed of ceramic material.

Disclosed are an apparatus and a method for extracting circumscribed rectangles of one or more characters in a transplantable electronic document. The apparatus comprises a command and resource extraction device for extracting text-segment-related commands and original font resources; a division device for dividing the original font resources into fonts; a font replacement device for seeking fonts, and obtaining font resources after font replacement; a measurement information extraction device for extracting character shape measurement information of the characters; and a calculation device for calculating the circumscribed rectangles of the characters.
摘要:
A method for controlling a structure of a nano-scale substance, which comprises irradiating a mixture of low-dimensional quantum structures having a nano-scale with an electromagnetic wave in an oxygen atmosphere, to thereby selectively oxidize a low-dimensional quantum structure having a density of states resonating with the electromagnetic wave used for the irradiation. The method allows a low-dimensional quantum structure having a specific structure to be selectively disappeared from the mixture of low-dimensional quantum structures having a nano-scale.

A disclosed method for extracting a raster image of a page from a portable electronic document that includes (a) acquiring commands and resources of the raster image of the page by analyzing a format of the portable electronic document, (b) extracting first and second candidate raster images by processing the commands and the resources of the raster image of the page, (c) integrating the first and second candidate raster images as an integrated candidate raster image provided that the first and second candidate raster images are linked together, and (d) removing a pseudo-raster image from the integrated candidate raster image.
摘要:
An adjustment unit identifies a front-rear driving force distribution control unit and a braking force control unit, and calculates based on the current vehicle state, a target yaw moment required for each of the front-rear driving force distribution control unit and braking force control unit. Then, based on the current operating state of each of the control units, a control correction value for each unit is calculated in consideration of the maximum value, and outputted.

It is an exemplified object of the present invention to provide a radiator mechanism and electronic apparatus having the radiator mechanism that can prevent destruction, deterioration, and malfunction due to heat of exoergic components or other electronic components, thermal deformation of a housing thereof, and low-temperature burn, without preventing the electronic apparatus including a printed board from miniaturization. The radiator mechanism is comprised of a cooling fan and a through hole provided in a motherboard, thereby thermally protecting a variety of circuit components mounted on the motherboard to provide a stable operation.
摘要:
Low-pressure-side condensate is subjected to convection heating while dripping in high-pressure-side steam, and to surface turbulent heat transfer due to a circulating flow caused by downflow condensate falling after overflowing. Thus, the temperature of the low-pressure-side condensate can be raised efficiently with satisfactory heat transfer. A bypass connecting pipe enables high-pressure-side condensate to bypass condensate of a reheat chamber and merge with the condensate while keeping a high temperature. Thus, heating of the low-pressure-side condensate is performed sufficiently, with a space for falling being minimized for compactness. Also, condensate in a high amount of heat exchange is fed toward a condensate pump. Hence, a multistage pressure condenser permitting compactness and increased efficiency of a power plant can be constructed.
摘要:
A portable electronic device having a body and a first slot formed in the body for selectively accommodating a battery and a first recording medium drive having substantially the same width as that of the battery. The first slot has a first width. The portable electronic device further has a second slot formed in the body for selectively accommodating a second recording medium drive having a width larger than that of the first recording medium drive and the battery with an attachment attached to a side surface thereof. The second slot has a second width larger than the first width of the first slot. With this configuration, the two batteries having the same shape can be simultaneously accommodated into the first and second slots, thereby allowing long-term driving of the portable electronic device.

Finely divided hydrophobic silica powder having a number average particle size from 3 to 10 nm and a BET surface area from 195 to 290 m.sup.2 /g is dry blended with particles of a thermosetting resin composition having a volumetric average particle size from 5 to 20 .mu.m in a proportion from 0.05 to 2.0 parts per 100 parts of the resin particles on weight basis. Sieving efficiency of the powder coating composition thus processed is remarkably improved.
