摘要:
An exposure device that sequentially projects and repeatedly transfers a predetermined pattern formed on a reticule onto wafers via an optical projection system, the exposure device including a movement unit that positions a current shot region on a wafer in the focal position of the optical projection system, a detection unit that detects tilting on an exposure surface of the current shot region with respect to an image plane of the optical projection system, and a plurality of first piezoelectric elements that correct the tilting on the current shot region with respect to the optical axis, based upon the detection results of the detection unit, so that the exposure surface of the current shot region will substantially match the image plane.

A fuel injector is provided which is designed to suppress unwanted vibrations of a nozzle needle-actuating piston, thereby avoiding the injection of an excess quantity of fuel. The fuel injector comprises an actuator and a displacement amplifying chamber filled with fluid to which a large-diameter piston and a small-diameter piston working as the nozzle needle-actuating piston are exposed. The displacement amplifying chamber works to amplify and transmit displacement of the large-diameter piston by the actuator to the small-diameter piston. The fuel injector also includes a stopper which restricts movement of the small-diameter piston toward the displacement amplifying chamber to a given range, thereby suppressing the unwanted vibrations of the small-diameter piston.

A valve actuating device is provided which may be employed in fuel injectors for automotive internal combustion engines. The valve actuating device includes an actuator, a large-diameter piston displaced by said actuator, a small-diameter piston operating a valve, a displacement amplifying chamber filled with working fluid to amplify and transmit displacement of the large-diameter piston to the small-diameter piston, and a drain passage. The drain passage communicates with the displacement amplifying chamber through a pinhole for draining the working fluid within the displacement amplifying chamber, thereby enabling the pressure in the displacement amplifying chamber to be released in order to ensure the movement of the small-diameter piston when the valve actuating device is started.
摘要:
An oral composition for caries prophylaxis which comprises a highly soluble stannous compound such as stannous fluoride preferably in an amount of 0.03 to 5% by weight of the composition as stannous tin, a difficultly soluble stannous compound such as stannous pyrophosphate preferably in an amount of 0.05 to 10% by weight of the composition as stannous tin, a phytic acid compound such as sodium phytate preferably in an amount of 0.1 to 20% by weight of the composition, and the pH of the composition being preferably acidic. A portion of the difficultly soluble stannous compound may be in a precipitate form. The oral composition which may be used as dentifrices, prophylactic pastes, dental flosses and the like permits n.sup.2+ ions to exert its effect because the storage stability is high enough to maintain the increased concentration of active dissolved stannous ions in the composition for a prolonged period of time and can render the tooth enamel more resistant to acid attack when applied to teeth.
摘要:
An object of the present invention is to provide a printing apparatus and a printing method even with a variation in the temperature of a print head, thus keeping the quality of images resulting from printing high. Adjustment patterns used to adjust the difference in ink ejection timing between ink ejected in a forward direction and ink ejected in a backward direction during scanning are printed at a plurality of different temperatures. Adjustment values for the ink ejection timing at the respective temperatures are selected from the adjustment patterns. Then, the correction value for the ink ejection timing is calculated from the adjustment values based on the temperature detected by the detection device. Printing is then performed with the difference in ink ejection timing between the ink ejected in the forward direction and the ink ejected in the backward direction during scanning, adjusted based on the correction value.

In a paper bill depositing/dispensing apparatus, when a roof plate and a stage plate move from a depositing/dispensing unit to a temporarily accumulating unit along with a deposited bill, rotations of a pick roller, a separator, a feed roller and a conveyance roller are driven to carry a bill to a conveyance path that connects to a bill storing unit, and a partial paddle wheel stops by orientating its round surface, not provided with paddles, toward a path of the carried bill. When a bill is dispensed, the separator, the feed roller and the conveyance roller rotate in a bill carry-in direction to carry the bill conveyed from the conveyance path in the temporarily accumulating unit, and the partial paddle wheel beats a rear end of the carried bill with paddles to align the rear end of the bill at a bottom position d.

A tire (2) includes a tread (4), a wing (6), a sidewall (8), a clinch portion (10), a bead (12), a carcass (14), a support layer (16), a belt (18), a band (20), an inner liner (22) and a chafer (24). A dimple (62) is formed in the sidewall (8) and the clinch portion (10). When air flows into the dimple (62), a turbulent flow is generated. By the turbulent flow, heat of the tire (2) is emitted to an atmosphere. The dimple (62) takes a planar shape of a circle. The dimple (62) has a diameter which is equal to or greater than 6 mm and is equal to or smaller than 18 mm. The dimple (62) has a depth which is equal to or greater than 0.5 mm and is equal to or smaller than 3.0 mm. The tire (2) has a CTT profile.
摘要:
An inkjet printing apparatus, a maintenance method and an inkjet printing system which are capable of precisely calculating the amount of satellites or ink mist generated and replacing a collecting mechanism at most appropriate time. The inkjet printing apparatus has a wind-powered collecting mechanism collecting generated sub-droplets such as satellites or ink mist, and head temperature sensors for obtaining temperature information of the print head. The CPU calculates the amount of sub-droplets generated on the basis of printing conditions including the detected temperature information of the print head. The CPU determines whether the replacement of the wind-powered collecting mechanism is necessary on the basis of the calculated amount of sub-droplets generated.

An object of the present invention is to provide an ink jet printing apparatus that inhibits the temperature of a print head from increasing excessively while preventing significant density or hue unevenness from occurring in images, without the need for a complicated structure or complicated control. Thus, the present invention detects temperature of the print head, and sets number of scans in which the print head is to stand by until start of scanning and a standby time for each of the set number of scans by the print head, on the basis of the detected temperature.
