The present invention restrains, during a transfer of a substrate, a central portion of the substrate from being warped by its own weight, which might be caused by a super-enlargement of a diameter of the substrate. A substrate transfer apparatus 18 includes: a support part 17 which is moved above a substrate w of a large diameter; and an upside grip mechanism 28 disposed on the support part 17, the upside grip mechanism 28 capable of supporting a peripheral portion of the substrate w from above. The support part 17 is provided with a non-contact sucking and holding part 30 having a suction hole 31 and a blow hole 32. The non-contact sucking and holding part 30 sucks and holds the substrate w in a non-contact manner, by blowing a gas onto the central portion of the upper surface of the substrate w and sucking the central portion to form an air layer 50 such that the central portion of the wafer w is not warped.

A sheet conveyance apparatus capable of detecting a sheet end portion in a short time period even if sheets are conveyed at a narrow interval and at high speed, thus making it possible to expedite the start timing of a subsequent sheet alignment operation. In accordance with results of detection by lateral registration detection sensors performed when a sheet reaches a lateral registration detection sensor unit, the sensor unit is moved in a width direction for sheet end detection. Based on a moving distance of the sensor unit from a standby position to a position where the sheet end is detected, a shift amount to be shifted the sheet in the width direction, i.e., a lateral registration error, is computed.

A vaporizer for generating a process gas from a liquid material includes a heat-exchange lower block having a hollow internal space and disposed below the spray port of an injector inside the container. A run-up space for the atomized liquid material is defined between the spray port and the heat-exchange lower block, and an annular space continuous to the run-up space is defined between an inner surface of the container and the heat-exchange lower block. An internal heater is disposed in the internal space of the heat-exchange lower block and includes a carbon wire formed of woven bundles of carbon fibers and sealed in a ceramic envelope. The internal heater is configured to heat the atomized liquid material flowing through the annular space to generate the process gas.

An image forming system which is capable of preventing paper jam from occurring in a sheet processing apparatus to thereby maintain the stability of the system. An alignment plates of an alignment unit movable in a lateral direction each sheet are brought into abutment with opposite side edges of sheets stacked on the sheet stack unit to laterally align the sheets. A lateral registration sensor unit detects a lateral position of the sheet being conveyed. When the detected lateral position of the sheet is beyond a predetermined position, the CPU of the apparatus changes the standby positions of the alignment plates such that spacing therebetween in the lateral direction the sheet is widened by a predetermined amount, and extends the conveying interval of sheets in the image forming apparatus by a predetermined time period.

An image forming system has a sheet deck assembly, an image forming apparatus, and a feeding buffering apparatus with plural feeding buffer trays for temporarily storing sheets of printing paper fed from plural printing paper decks of the sheet deck assembly. The feeding buffering apparatus feeds the temporarily stored sheets to the image forming apparatus.

In an automotive vehicle body including a first annular frame (29) formed by front pillars (11, 12), a second annular frame (34) formed by center pillars (13, 14) and a front door (7) internally provided with a front door beam (51) and fitted between the front pillar and center pillar one each side of the vehicle body, the front door beam overlaps the first annular frame and second annular frame as seen from sideways, and includes a door beam main body (61) providing a channel member having an open side facing inboard and a tension wire (71) extending along an inboard side of the door beam main body. Thereby, when another vehicle hits the front door from sideways, because the front door beam overlaps the first annular frame and second annular frame as seen from sideways, the impact energy can be effectively transmitted to the vehicle body. Furthermore, because the door beam main body supports a compressive load while the tension wire supports a tensile load, deformation of the door beam is minimized.
