In another aspect, an alignment apparatus which includes a first off-axis alignment optical system having a magnification, a second off-axis alignment optical system having a magnification higher than that of the first off-axis alignment optical system, and a TTL alignment optical system, wherein the alignment apparatus is operable in a global alignment mode using the second off-axis alignment optical system and is operable in another global alignment mode using the TTL optical alignment system.
摘要:
A method for operating a plural number of batch type reduced-pressure fryer units, the method including: connecting the fryer units, through a switch means, with vacuum pump lines including an initial vacuum pump line serving to reduce the frying bath pressure of a selected one of the fryer units in the stage of an initial frying treatment and a finish vacuum pump line serving to maintaining the frying baths of a plural number of the frying units simultaneously in reduced pressure condition in the stage of a finish frying treatment; while holding the respective vacuum pump lines in operation, switching the vacuum pump lines to connect the initial vacuum pump line with a selected fryer unit to reduce the pressure of the frying bath thereof for the initial frying treatment; switching the vacuum pump line to connect the selected fryer unit with the finish vacuum pump line for the finish frying treatment upon completion of the initial frying treatment; switching the vacuum pump lines to disconnect the selected fryer unit from the vacuum pump lines upon completion of the finish frying treatment; and repeating the switching operation sequentially and cyclically for each one of the fryer units in a predetermined timing.
摘要:
An exposure apparatus for aligning an original, having at least one alignment mark thereon, and radiation sensitive member, having at least one alignment mark thereon and adapted to receive the image of the original, with each other includes a first detecting device including a sensor retractable from the optical path of a light for illuminating the original, the sensor being adapted to sense the original and radiation sensitive member to detect a relative displacement (degree of misalignment) between the original and radiation sensitive member when the sensor is in the optical path; a second detecting device including a sensor set out of the optical path and adapted to detect the position of one of the original and radiation sensitive member in the absolute coordinates of the apparatus; and a driving mechanism for moving one of the original and radiation sensitive member in response to the output of the second detecting device to correct the above mentioned displacement.
摘要:
In a divisional printing apparatus wherein the pattern of a mask is reduced and projected for printing onto a wafer and the mask and the wafer are moved relative to each other at each shot so that the exposed areas thereof do not overlap each other, and whereby the same pattern as that for collective printing is printed onto the effective area of the wafer by a plurality of shots, a shot arranging method in which, in the case of a so-called multichip shot in which a plurality of chips are exposed at a time at each shot, the special chip area of the wafer is not exposed, but the wafer is effectively exposed so that the creation of unusable chips is minimized.
摘要:
A dual intake valve type internal combustion engine comprises a main intake valve and an auxiliary intake valve. The main intake valve is so constructed that the combustible gas mixture introduced into the combustion chamber therethrough is caused to generate a swirl motion. A variable valve lift type of auxiliary intake valve is constructed, and the valve lift of the auxiliary intake valve is varied in accordance with the changes in the engine operating conditions.

A method of processing light-sensitive silver halide photographic material to be treated with a developing solution containing no hydroquinones developing agent, which material comprises a support, a silver halide emulsion layer coated thereon containing silver halide grains having an average grain size of 0.1 to 0.8.mu., at least 75% of said grains being within a range of 0.6 to 1.4 times the said average grain size, and a tetrazolium specified compound.
摘要:
A resinous composition having fire retardance, impact resistance and easy workability is obtained by blending (1) about 80 to 30 parts by weight of an ABS resin with (2) about 20 to 70 parts by weight of (i) a vinyl chloride resin compound comprising 100 to 5 parts by weight of a copolymer resin consisting essentially of 0.5 to 40% by weight of a higher alkyl vinyl ether and 99.5 to 60% by weight of vinyl chloride and (ii) 0 to 95 parts by weight of a polyvinyl chloride resin.
摘要:
Process of forming a high-contrast silver image which process comprises treating a light-sensitive silver halide photographic material comprising a support, a silver halide emulsion layer coated thereon and another hydrophilic colloidal layer, at least one of which contains a substantially non-diffusible compound having oxidation power on a hydroquinone developing agent, with a developer containing no hydroquinone developing agent after exposed imagewise.
