摘要:
An edge exposing apparatus includes a photo detector and a lighting time measuring circuit for detecting a decrease in performance of light source units. The lighting time measuring circuit detects a ready state ((stabilization of luminous intensity) of the light source units, for example by measuring a lighting time for a startup (switch-on) of the light source units. When the measuring circuit detects a preset lighting time, or when the photo detector detects a luminous intensity below a preset value, the light source units are determined to have lowered performance, and are switched off. When a decrease in performance of one unit is detected, a replacement light source unit is started while continuing edge exposure with one or more other light source unit(s). When a ready state is detected, the edge exposure with the one light source unit is terminated (switch-off), and edge exposure is performed with the replacement light source unit.

A stage assembly (10) for independently moving and positioning a first device (26A) and a second device (26A) in an operation area (25) is provided herein. The stage assembly (10) includes a stage base (12), a first stage (14), a first mover assembly (15), a second stage (16), and a second mover assembly (18). The first mover assembly (15) moves the first stage (14) and the first device (26A) into the operational area (25) and the second mover assembly (18) moves the second stage (16) and the second device (26B) into the operational area (25). The present stage assembly (10) reduces and minimizes the amount of reaction forces and disturbances that are transferred between the stages (14), (16). This improves the positioning performance of the stage assembly (10). Further, for an exposure apparatus (30), this allows for more accurate positioning of two semiconductor wafers (28) relative to a reticle (32) or some other reference.

An edge exposing apparatus includes a photo detector and a lighting time measuring circuit for detecting a decrease in performance of light source units. The same lighting time measuring circuit has a function to detect a ready state (i.e. stabilization of luminous intensity) of the light source units capable of performing edge exposure. When the lighting time measuring circuit detects a lighting time having reached a preset value, or when the photo detector detects a luminous intensity below a preset value, the light source units are determined to have lowered in performance, and are switched off. The lighting time measuring circuit measures a lighting time from a startup (switch-on) of the light source units, and when the lighting time reaches a preset value, the light source units are determined to have attained the ready state and edge exposure is started with the light source units. When a decrease in performance is detected, one light source unit is started while continuing edge exposure with the other light source unit. When a ready state is detected, the edge exposure with the light source unit is terminated (switch-off), and edge exposure is performed with the light source unit having attained the ready state.
摘要:
A filling machine for producing containers containing liquid food product includes a series of rollers for forming a web-shaped packaging material into a tubular packaging material, a filling tube for introducing a liquid food product into the tubular packaging material while the tubular packaging material is being conveyed downwardly, a heat sealing bar providing with a heating mechanism and engageable with a cutting bar to produce a seal area forming a transverse seal across the tubular packaging material below a level of the liquid food product, and a cutter provided on the cutting bar to cut the tubular packaging material in the seal zone to form a preformed container containing the liquid food product. At least one nozzle is positioned to direct a sterilizing flushing liquid towards the outside surface of the tubular packaging material and/or the cutter. The flushing liquid advantageously cleans and sterilizes the outer surface of the tubular packaging material, and is able to flow downwardly to wash and sterilize the sealing bar and the cutter. Also, the flushing liquid can cool the packaging material after the formation of the transverse seal and so the plastic or resin material of the packaging material is relatively rapidly hardened. It is thus less likely that the plastic or resin material will be stained or soiled. As a result, the appearance of the packaging material is improved.

A positioning apparatus positions a movable body 6 on which a wafer W (object to be positioned) is mounted, and includes; a magnetism generation body 8 incorporated in the movable body 6, a magnetic member 10, 15A, 15B, 16 formed so as to have the magnetism generation body 8 therebetween, and a drive unit 11 disposed between the magnetism generation body 8 and the magnetic member 10, for driving the magnetism generation body 8, and the movable body 6 is positioned by means of the magnetic member 10 etc. and the drive unit 11. The positioning apparatus can position a movable body (object to be positioned) at a high speed and with high precision, and is suitable for use for example with an exposure apparatus or the like for positioning a wafer at high precision.
摘要:
A packaging container having an enhanced sealing performance includes a packaging material, an outside strip and a strip tape. The opposite side edges of the packaging material are overlapped with each other so that the outermost layer and the innermost layer of the packaging material face each other. The outside strip is interposed between the outermost layer and the innermost layer and is fused and joined with these layers so that a longitudinal sealing portion is formed. The outside strip has an outside layer and an inside layer. The strip tape is placed on the inner surface of the packaging container along the sealing portion, and is joined thereto by heat fusion. The innermost layer of the packaging material and the outside layer of the outside strip are made of a non-olefin flavor-retaining resin, and the outermost layer of the packaging material and the inside layer of the outside strip are made of a polyolefin resin. Since portions to be joined at the longitudinal sealing portion are both polyolefin, an enhanced sealing performance can be obtained.

摘要:
An exposure apparatus for forming a predetermined pattern on a substrate by using exposure light, includes a stage apparatus which is movable with respect to an optical axis of the exposure light; a light-transmissive member provided at the stage apparatus, wherein a liquid is supplied on an upper surface of the light-transmissive member; and a measurement device which is settable below the light-transmissive member when measurement using the measurement device is performed. Leakage or entrance of a liquid used for exposure into an optical measurement device such as a wavefront aberration measurement device can be prevented, thereby enabling preferable optical adjustment such as imaging performance or optical characteristics.
摘要:
An exposure apparatus fills a space between a projection optical system and a substrate with a liquid and projects a pattern image onto the substrate to expose the substrate. The projection optical system has a first group including an optical member that comes into contact with the liquid, and a second group that differs from the first group. The first group is supported by a first support member via a vibration isolating apparatus.
