摘要： An optical compensatory sheet producing apparatus produces an optical compensatory sheet having a liquid crystal layer. In the apparatus, a rubbing unit is supplied with resin film having a first layer including resin, and subjects the first layer to a rubbing process, so as to form an orientation layer. A dust remover removes dust from the orientation layer by use of liquid such as perfluorocarbon, to which the orientation layer is insoluble. A liquid crystal layer coater is disposed downstream from the dust remover, for coating the orientation layer with coating liquid including liquid crystalline compound, so that the liquid crystal layer is formed.

摘要： A customer holds a personal data card (personal data card) which stores data of five music pieces including music-piece codes of favorite karaoke music pieces, and the key and tempo setting of the music pieces as my-song data. The customer inserts the personal data card into a card insertion slot. The five my songs are assigned to music-piece selection switches, respectively. The music pieces can be selected only by turning on one of the music-piece selection switches. Unlike a usual music-piece selection, therefore, it is not required to input a music-piece code consisting of five to seven digits. When a start switch is turned on thereafter, the music piece is started. Prior to the start, the key and tempo stored in the personal data card are set. Therefore, the setting with which the customer sings the song in best conditions can be automatically performed. In addition, when favorite setting of a favorite song is obtained during the performance of a karaoke music piece, the music-piece code and the setting data of the music piece are written into the personal data card by turning on a writing switch. At the next time and thereafter, the music piece and the setting can be selected by turning on only the music-piece selection key or one-flick selection.
摘要翻译：客户持有个人数据卡（个人数据卡），其存储五个音乐作品的数据，包括喜爱的卡拉OK音乐片段的音乐片段，音乐片段的关键和速度设置作为我的歌曲数据。客户将个人数据卡插入卡插槽。我的五首歌曲分别分配给音乐片段选择开关。只能通过打开其中一个音乐选择开关来选择音乐。因此，与通常的音乐片段选择不同，不需要输入由五到七位数组成的音乐片段。当此后开启启动开关时，乐曲开始。在开始之前，设置存储在个人数据卡中的键和速度。因此，可以自动执行用户在最佳条件下唱歌的设置。此外，当在卡拉OK乐曲演奏期间获得最喜欢的歌曲的喜好设定时，音乐片段的音乐片段和设置数据通过打开写入开关被写入个人数据卡。在下一次和之后，可以仅通过打开音乐片选择键或单击选择来选择乐曲和设置。

摘要： A disc drive for a disc including a disc rotating apparatus comprising a rotating shaft for being received within a first aperture of the disc. A spindle is affixed to the shaft. The spindle has a surface disposed in a plane perpendicular to the shaft, for supporting the disc. The disc drive includes a position controlling member received in a second aperture of the disc, a rigid member for controlling the position of the position controlling member, and a biasing member for urging the rigid member in at least one direction so that the position controlling member engages the disc. A centering force to center the disc on the disc rotating apparatus is produced due to the action of the position controlling member on the disc. The biasing member may be configured so as to act upon the rigid member in an additional direction to produce an additional centering force component when the position controlling member engages the disc, thus urging sides of the first aperture of the disc against the rotating shaft. The rigid member has a first portion pivotally attached to the disc rotating apparatus at a point removed from the rotating shaft and a second portion for supporting the position controlling member. The second portion of the position controlling member is configured to support the position controlling member so that it is angled forward with respect to the direction of rotation of the disc, to aid in holding the disc firmly on the spindle.
