    • The present invention relates to a disk recording and/or reproducing apparatus in which a disk-like recording medium such as an optical disk is transported between a disk loading portion provided for recording and/or reproducing information and a disk unloading portion for inserting and ejecting the disk-like recording medium. The disk recording and/or reproducing apparatus includes a pair of transport members for holding a disk-like recording medium in its diametrical direction, a drive means for driving a first transport member of the pair of transport members and giving rotation force to rotate and move the disk-like recording medium held between the pair of transport members and a space adjusting mechanism capable of adjusting a space by making the pair of transport members become close to or away from each other in response to the size of the disk-like recording medium. The disk-like recording medium can reliably be held in the diametrical direction by adjusting a space between the pair of transport members with the space adjusting mechanism in response to the size of the disk-like recording medium and the disk-like recording medium can be rotated, moved and transported by rotation force applied thereto. Therefore, when the disk is transported, the signal recording surface can be free from being touched, the signal recording surface can be prevented from being pressed by foreign material and the signal recording surface can be prevented from being scratched by the foreign material. Thus, an information signal can reliably be read and written.
    • 盘记录和/或再现装置技术领域本发明涉及一种盘记录和/或再现装置,其中诸如光盘的盘状记录介质在用于记录和/或再现信息的盘装载部分和用于插入和弹出的盘卸载部分之间传送 盘状记录介质。 磁盘记录和/或再现装置包括一对用于在其直径方向上保持盘状记录介质的传送构件,驱动装置,用于驱动一对传送构件的第一传送构件并产生旋转和移动的旋转力 保持在一对传送构件之间的盘状记录介质和能够通过使一对传送构件相对于盘状记录介质的尺寸彼此靠近或远离而调节空间的空间调节机构 。 通过根据盘状记录介质的尺寸,通过利用空间调节机构调节一对传送部件之间的空间,盘状记录介质可以可靠地保持在该直径方向,并且盘状记录介质可以 通过施加到其上的旋转力旋转,移动和运送。 因此,当传送盘时,信号记录表面可以没有被触摸,可以防止信号记录表面被异物压住,并且可以防止信号记录表面被异物刮伤。 因此,可以可靠地读取和写入信息信号。

    • A process for producing isobutylene and methanol comprising: a first step of subjecting methyl-tert-butyl ether to decomposition in the presence of a catalyst to obtain a reaction liquid; a second step of washing the resultant with water to separate the reaction liquid into an oil layer and an aqueous layer; a third step of subjecting the oil layer to distillation to obtain a fraction containing isobutylene and a dialkyl ether from the top of a distillation column, a fraction containing methyl-tert-butyl ether and the heavy components from the bottom of the column and a fraction containing methyl-tert-butyl ether from a side cut of the column, and recycling the side cut fraction to the first step; and a fourth step of subjecting the aqueous layer to distillation to obtain a fraction containing methanol from the top of a distillation column and a fraction containing water from the bottom of the column.
