    Abstract: A crucible protection sheet is provided that can prevent damages to an inner crucible, hinder an outer crucible from silicon-carbidization, and transmit heat from the outer crucible to the inner crucible uniformly.In a crucible having an inner crucible 2 and an outer crucible 3, the crucible protection sheet is arranged between the two crucibles and is made of expanded graphite. The planar thermal conductivity is 120 W/(m·K) or higher, the gas permeability is less than 1.0×10−4 cm2/s, and the compression ratio is 20% or higher when the sheet is compressed in a thickness direction at a pressure of 34.3 MPa. Since the compression ratio is high, the effect of preventing breakage is great when inserting the inner crucible, improving workability and preventing the inner crucible from tilting inside the outer crucible. In addition, even though the compression ratio is high, the thermal conductivity is kept to such a degree that the inner crucible can be heated uniformly, and the gas shielding capability is also ensured. As a result, the outer crucible is prevented from silicon-carbidization and thickness decrease.

    Abstract: An information reproduction and recording apparatus able to prevent invalid data not required for recording from being recorded on a recording medium when transferring reproduced information by a small number of signal lines such as a three-line serial peripheral interface, wherein a music data reproducing unit outputs a data signal DATA and clock signals LRCK and BCK to a valid recording period control unit and outputs a SPACE signal to the valid recording period control unit while outputting music data containing track interval data, the signals are transferred to a high speed encoder and the data signal DATA is encoded and recorded on a hard disk by an HDD based on the clock signals LRCK and BCK while the SPACE signal is being output, and the valid recording period control unit suspends transfer of the clock signal LRCK and prevents recording of invalid data on the hard disk while the SPACE signal is not being output.
