    摘要: A single crystal pulling apparatus (1) has a quartz crucible (2) for accommodating silicon melt (3), a graphite crucible (4) for retaining the quartz crucible (2), a tray (5) for securing and holding the graphite crucible (4) from below, and a crucible rotating shaft (6) for supporting the tray (5) from below and for elevating and lowering the tray (5) and the crucibles (2), (4) while rotating them. A low heat conductive member (10) is interposed on a joint surface between the tray (5) and the crucible rotating shaft (6). The low heat conductive member (10) is formed in a substantially tubular shape, and is interposed in such a manner that a protruding portion of the crucible rotating shaft (6) is inserted through a center hole of the low heat conductive member (10). Thereby, a gap portion (11) is formed below a bottom portion of the tray (5).

    摘要: A graphite crucible (2) for retaining a quartz crucible (1) has a graphite crucible substrate (3) as a graphite crucible forming material, and a coating film (4) made of a carbonized phenolic resin and formed over the entire surface of the graphite crucible substrate (3). The phenolic resin is impregnated inside open pores (5) existing in a surface of the graphite crucible substrate (3). The coating film (4) may be formed only within a portion of the graphite crucible in which SiC formation can occur easily, not over the entirety of the surface of the graphite crucible. For example, it is possible to deposit the film only on the entire inner surface of the crucible. It is also possible to deposit the film only on a curved portion (sharply curved portion) of the inner surface, or only on a curved portion and a straight trunk portion.

    摘要: A carbon crucible prevents leakage of SiO gas from a boundary portion between a straight trunk portion and a tray portion and prevents SiC formation from quickly developing. A carbon crucible (5) for retaining a quartz crucible (4) used in a metal single crystal pulling apparatus for silicon or the like has a straight trunk portion (9) and a tray portion (10) that are divided from each other. A graphite sheet (11) is disposed between the quartz crucible (4) and the carbon crucible (5) so as to cover at least a boundary portion (A) of an inner surface of the carbon crucible (5) between the straight trunk portion (9) and the tray portion (10). The graphite sheet (11) is an expanded graphite sheet.

    摘要: A feeder has a longer side direction orthogonal to a conveyance direction of a recording medium, and is configured to feed a maximum size recording medium with a longer side first. An image forming unit has a maximum sheet feed width corresponding to a longer side length of the maximum size recording medium, and is configured to print a toner image corresponding to digital image data onto the recording medium. An electrical component unit is configured to control the feeder and the image forming unit. The image forming unit and the electrical component unit are respectively disposed on both sides of the feeder in a shorter side direction.
