摘要:
In a fuel-injection system with a pressure regulator disposed in the middle of a fuel supply line and located upstream of a fuel injector for regulating the pressure of fuel flowing through the fuel supply line and for returning surplus fuel via the pressure regulator into a fuel tank, a reflux pipe arrangement is located downstream of the fuel injector and connected at one end to the downstream end of the fuel supply line and connected at the other end to the fuel tank. A reflux control device is disposed in the middle of the reflux pipe arrangement for controlling a flow rate of the fuel flowing through the reflux pipe arrangement. The reflux control device is comprised of a reflux control valve or a fluid-flow restriction orifice member.

A fuel injector includes a valve seat member formed with a valve seat and a valve element including an abutting portion to abut on an abutting portion of the valve seat. One of the abutting portions of the valve seat and the valve element includes a surface layer which is softened by heat treatment, and which is pressed by abutment between the valve seat and the valve element.

A fuel injector includes a tube member and a valve element to slide axially in the tube member. The valve element includes a center portion and a plurality of plate portions projecting radially from the center portion, and each including side surfaces extending axially; and a guide section including an outer portion defining a valve seat, and an inner portion which is located on a radial inner side of the outer portion, and which is formed with at least one injection hole. The guide section is arranged to divert the flow of the fuel conveyed along the plate portions, to a radial inward direction toward the injection hole.

A toner is provided. The toner contains a polyester resin. The toner has a glass transition temperature (Tg1st) at first temperature rising of differential scanning calorimetry (DSC) of from 45° C. to 65° C. The toner includes a component insoluble in tetrahydrofuran (THF) having two glass transition temperatures (Tga1st and Tgb1st) at the first temperature rising of DSC, where Tga1st is in a range of −45° C. to 5° C. and Tgb1st is in a range of 45° C. to 70° C. The toner includes a component soluble in THF having a glass transition temperature (Tg2nd) at second temperature rising of DSC of from 40° C. to 65° C.

A vehicle image processing apparatus includes: a group of cameras; a drawing unit that converts a captured image into an image viewed along a line of sight running from a predetermined position in a predetermined direction; a viewing-line-of-sight changing unit that detects whether a first line of sight is switched to a second line of sight; and a viewing-line-of-sight generation/updating unit that acquires parameters concerning the first and second lines of sight after detecting the switching and generates a parameter which is gradually changed from the parameter of the first line of sight to the parameter of the second line of sight. Moreover, the drawing unit generates, on the basis of the gradually changed parameter, an image which is gradually changed from an image viewed along the first line of sight to an image viewed along the second line of sight.
摘要:
A particulate material production method is provided. The particulate material production method includes ejecting a particulate material composition liquid, which includes an organic solvent and a particulate material composition including at least a resin and dissolved or dispersed in the organic solvent, from at least one nozzle to form droplets of the particulate material composition liquid in a gas phase; and solidifying the droplets of the particulate material composition liquid to prepare particles of the particulate material composition. The droplet solidifying step includes contacting the droplets with a poor solvent for the particulate material composition.
