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).

The present invention discloses a method of controlling combustion of a fluidized-bed incinerator. In a fluidized-bed incinerator (5), a method of controlling combustion of the fluidized-bed incinerator comprises measuring a supply rate of incineration waste by a supply rate measuring unit (11) using a photoelectric element (1) arranged on a shoot (2) for supplying incineration waste (3) from a dust feeder (4) to the incinerator (5), and when the supply rate of incineration waste is higher than a predetermined value, decreasing a supply rate of incineration waste of the dust feeder 4 to suppress a combusting operation, increasing an induced gas rate of an exhaust gas induced blower (9) of the incinerator to suppress an increase in an incinerator internal pressure decreasing a flow rate of fluidizing air of a forcing blower (7) to suppress a combusting operation, or increasing a flow rate of a blower (8) for supplying air to a free board portion to prevent production of an unburnt gas.

In case where a key having a detection region (inner frame) in which user's instructions can be accepted is displayed according to a certain operation status of an apparatus, and in case where there is an invalid region in which the user's instruction is not detectable is adjacent to a key display region (outer frame) of the key, the detection region of the key is caused to be larger than the key display region by utilizing the invalid region. Moreover, the detection region is expanded/shrunk according to key arrangement and a number of keys to be displayed. With this, the detection region of the key is expanded/shrunk according to according to the key arrangement on the screen in a display-cum-operation device in which a display device and a coordinate input device are integrated.
摘要:
A carbon/silicon composite material wherein a silicon carbide containing carbon layer which is formed by silicon and boron carbide being penetrated from a surface of a carbon substrate into the inside thereof to allow the silicon and carbon of the carbon substrate to react with each other so as to be converted into silicon carbide and in which the silicon carbide is dispersed generally uniformly along a depth direction is formed on the carbon substrate as a first layer, the silicon carbide containing carbon layer having a thickness of not less than 1 mm.
