摘要:
A trochoid oil pump, which enables the endurance to be increased and the reduction of discharge pulsations and noise to be achieved, and in which those results can be realized with a very simple structure.An interdental space constituted by an inner rotor and an outer rotor having trochoid tooth profile or substantially trochoid tooth profile starts a compression stroke in the location of a partition section between an intake port and a discharge portion, and a linking gap L is composed by the interdental space and a preceding adjacent interdental space realized in a discharge stroke. The linking gap expands gradually from the start of compression stroke to the discharge stroke.

A ground color main extruder 9 which supplies a ground color resin that is to cover a strand conductor 3 is disposed. Plural stripe sub extruders 21 and 31 which supply a colored resin in a strip-like manner in a longitudinal direction of the strand conductor 3 simultaneously with extrusion of the ground color resin are disposed. Insert molds 16 and 17 are multiply disposed. While alternatingly switching over the stripe sub extruders 21 and 31 each time when a colored resin to be supplied is changed, a colored resin of a predetermined color is supplied through a path which is disposed for each of the stripe sub extruders 21 and 31.

A cleaning device includes first to third cleaning members that clean a surface of an endless belt that is looped over rollers including a driving roller. The first cleaning member is brought into contact with and separated from the surface at a predetermined timing. The second cleaning member is disposed upstream of the first cleaning member and downstream of the driving roller in a movement direction of the endless belt. The second cleaning member is in contact with the endless belt so as to prevent a tension variation of the endless belt caused by the first cleaning member from affecting the driving roller. The third cleaning member is disposed downstream of the first cleaning member. A contact state in which the third cleaning member is in contact with the endless belt is switched from a first contact state to a second contact state so as to reduce the tension variation.

According to one embodiment, coupling capacitance in a state in which a first heat radiation member is arranged between parallel flat plates of a first capacitor formed by a surface of a housing opposed to one surface of a printed circuit board and the printed circuit board is smaller than coupling capacitance in a state in which an integrally formed object having a relative dielectric constant of 5.8 is arranged between the first capacitor to cover a first radiating region containing the controller and the first nonvolatile semiconductor memories.

Methods and articles of manufacture for integrated, automatic pseudo localization of software applications are disclosed herein. A pseudo localization process, comprised of one or more utility applications, is integrated into a build cycle for a developing software application to generate pseudo-translated user-interface code as part of a build process. A build application may then generate a pseudo-language build of the developing software application and/or development database to enable testing and identification of internationalization defects that would prevent effective localization of the software product for the international market.

The present invention provides a vertical MOSFET which has striped trench gate structure which can secure avalanche resistance without increasing Ron. A vertical MOSFET 100 comprises a plurality of gate trenches 7 which is arranged in stripes, an array which is sandwiched with the plurality of gate trenches 7 and includes N+ source regions 4N+ and P+ base contact regions 5P+, and a diode region (anode region 6P+) which is formed so as to contact with two gate trenches 7. The N+ source regions 4N+ and the base contact regions 5P+ are alternately arranged along a longitudinal direction of the gate trench 7. Size of the diode region (anode region 6P+) corresponds to at least one of the N+ source regions 4N+ and two of the P+ base contact regions 5P+.
