摘要:
An electric compressor (201) includes: a compressor (203) configured to compress a refrigerant, the compressor (203) having a plurality of passage ports (207) delivering the refrigerant; an electric motor (205) configured to drive the compressor (203), the electric motor (205) having a plurality of stators (17) and an accommodation chamber (213) accommodating the plurality of stators (17); a partition wall (215) separating the compressor (203) and the an accommodation chamber (213) of the electric motor (205); and a plurality of refrigerant introducing/discharging passages (219) formed at the partition wall (215) wherein the respective refrigerant introducing/discharging passages (219) are located in a circumferential direction of the accommodation chamber (213), thereby the refrigerant being introduced into and discharged from stators (17) end in the electric motor (205) through the respective refrigerant introducing/discharging passages (219).
摘要:
In a control device for an automatic transmission having a flow control mechanism that causes a part of a working oil discharged from a mechanical oil pump to flow into the mechanical oil pump when a differential pressure between an upstream side and a downstream side of a narrowed portion increases beyond a predetermined value, the narrowed portion being provided in a discharge passage through which the working oil discharged from the mechanical oil pump flows, a line pressure is raised when an oil temperature of the working oil is equal to or higher than a predetermined oil temperature and an engine torque is equal to or smaller than a predetermined engine torque.
摘要:
A development roller, including a development sleeve disposed near a photo conductive drum, a magnetic roller disposed in the development sleeve, and a supplying device configured to supply a developer including a toner and a magnetic carrier to the photo conductive drum uniformly, the development sleeve having an outer surface on which the developer including the toner and the magnetic carrier is adsorbed by a magnetic force of the magnetic roller.
摘要:
A toner including at least one polyester resin serving as a binder resin, a colorant, a releasing agent, and a fixing aid, wherein the fixing aid includes a fatty acid amide-based compound, and the fatty acid amide-based compound is at least one of a fatty acid amide compound having a mono- or higher valent amide bond and a fatty acid amide-based compound having a mono- or higher valent amino group or a hydroxyl group.
摘要:
A method of manufacturing a hollow body having an external surface randomly provided with a large number of depressions is provided. The method includes providing the large number of depressions on the external surface of the hollow body. A profile curve of the external surface in a circumferential direction is obtained while rotating the hollow body. A frequency analysis is performed on the obtained profile curve. A quality of the hollow body is judged by comparing a result of the frequency analysis with a predetermined judgment standard.
摘要:
A toner for electrophotography, including a release agent; a binder resin; a colorant; and an external additive, wherein the binder resin is a polyester resin, and wherein the toner has a loss on heat not greater than 0.40% by weight at 165° C. and a difference between a loss on heat at 200° C. and the loss on heat at 165° C. not greater than 0.50% by weight, and includes a n-paraffin in an amount not less than 3% by weight.
摘要:
A lubricating oil reservoir provided at the bottom of a housing is placed under the compression mechanism or electric motor in the vicinity of the mounting bracket provided on the lower outside of a middle case. The lubricating oil reservoir can be provided efficiently using dead space formed under the compression mechanism in the housing, and the rigidity of the mounting bracket can secure the strength of the lubricating oil reservoir.
摘要:
A water-dispersible polyisocyanate composition comprises a hydrophobic polyisocyanate (A) and a vinyl polymer (B) having a nonionic group and an isocyanate group, in which the hydrophobic polyisocyanate (A) can be dispersed in a water-based medium by the vinyl polymer (B) having a nonionic group and an isocyanate group. The water-dispersible polyisocyanate composition is produced by reacting a hydrophobic polyisocyanate with a vinyl polymer (b) having a nonionic group and an active hydrogen group-containing group capable of reacting with an isocyanate group at a molar ratio of the isocyanate group to the active hydrogen group-containing group of 3 to 350.
摘要:
A semiconductor device comprises a BGA substrate having one principal plane furnished with a large number of solder balls, the solder balls constituting a ball grid array; a semiconductor chip mounted on another principal plane of the BGA substrate, the semiconductor chip being electrically connected to the BGA substrate by metal wires; and chip capacitors mounted on the semiconductor chip to reduce power source noise.
