Provided is a polylactic acid-based polyol composition in which a catalyst that remains in the polylactic acid-based polyol and that acts also as a catalyst for urethane formation has been deactivated by easy means. Thus, the polylactic acid-based polyol composition suffers from little influence of the catalyst on urethane formation. When the polylactic acid-based polyol composition is used as a raw material for a urethane resin, therefore, uniform molded products can be obtained. Also provided are a process for the production of the polylactic acid-based polyol composition, a urethane resin composition obtained using the polylactic acid-based polyol composition, a process for the production of the same, and molded products thereof. The polylactic acid-based polyol composition is a composition which comprises both a polylactic acid-based polyol prepared by transesterification and a silica compound and in which the silica compound has a surface area of 40 m2 or more based on 100 g of the polylactic acid-based polyol and a content of the silica compound is 70 wt % or less.

A projector, which projects color images using the three liquid crystal panels (41-43) while cooling them by the fans (611-613) for G, R, and B panels, comprises the level calculation unit (711) for finding the intensity levels of the R, G, and B components of image signals, the level calculation unit (721) for finding the voice levels of voice signals, the fan control unit (73) for controlling the numbers of revolutions of the fans (611-613), and the memory (761) for storing the cumulative amount of lighting time of the lamp (21). As the intensity levels get higher, the numbers of revolutions of the fans are increased, and as the cumulative amount of lighting time becomes larger, the numbers of revolutions of the fans are decreased. As a result, unnecessary noises caused by the fans (611-613) can be reduced while the liquid crystal panels (41-43) are properly cooled. Thus, the present invention has an object of reducing the noise of the fan which cools the display devices such as liquid crystal panels in a projector. Thus, the object of the present invention is to realize a reduction in noise caused by the fan for cooling a display device such as liquid crystal panels in a projector.

摘要:
If a user operates a DIP switch on an operator panel of a library apparatus, and sets a mass loading mode, a carrying unit repeats operations for loading a storage medium from a loading/unloading aperture to a slot. In a mass unloading mode, the carrying unit repeats operations for carrying the storage medium from the slot to the loading/unloading aperture. Consequently, even if a door for loading/unloading a mass of storage media is not arranged, the equivalent capability is implemented.

A tray is provided in an apparatus main body so that it can be freely loaded or unloaded in the depth direction. The tray is enclosed in an enclosing port of the front portion. A plurality of magazine racks each having a plurality of slots which can enclose media are arranged in the depth direction in the tray. The medium in the magazine rack is conveyed between an optical disk drive and the rack by an accessor provided in the apparatus. The magazine rack has a box-shaped rack main body which is opened only in the lateral direction for the loading/unloading direction of the tray in a tray enclosing state. The rack main body has a handle in the upper portion so as to be freely folded down. An emulation unit selects a form by a dip switch. In the first type, all of the optical disk media emulates a hard disk drive of one volume. In the second type, each of a plurality of optical disk media emulates a hard disk drive of one volume. Further, in the third type, a predetermined number of media among the plurality of optical disk media enclosed in the magazine rack are grouped and each group emulates a hard disk drive of one volume.
