Abstract: PURPOSE:To prevent self-excited oscillation of blades without providing a damping member, facilitate manufacturing and assembling, and prevent generation of partial stress by forming a cascade of blades while embedding a group of the blades around a rotor with groups having quite different characteristic oscillation numbers being arranged adjacently. CONSTITUTION:In a cascade of blades an axial flow turbo machine having a cascade of blades formed by embedding a plurality of blades 6 around a rotor 7, the blades 6 are classified into some groups according to their characteristics oscillation numbers, while the groups of blades 6 are embedded around the rotor 7 with groups having quite different characteristic oscillation numbers being arranged adjacently. That is, a group 1 of the blades 6 is embedded adjacently to a group (n) having a quite different characteristic oscillation number therefrom. Further, the group (n) of the blades 6 is embedded adjacently to a group 2 having a quite different characteristic oscillation number therefrom. Self-excited oscillation is therefore prevented without providing a damping member on the cascades embedded around the rotor 7.

Title: Method and device for reproducing optical disk
Inventor: KIKUCHI SHINICHI
IPC: H04N5/93
Filed: 1997-11-25
Abstract: PROBLEM TO BE SOLVED: To make an optical disk reproducing device more conveniently usable by continuously outputting audio outputs with the data of already transferred data units while retrieval is performed by newly deciding an address to be retrieved based on retrieval information from a navigation pack at the time of performing special reproducing processing, such as the fast forwarding or fast running. SOLUTION: On an optical disk 10, many audio packs are time sequentially stored in video object units(VOBU) to be reproduced and navigation packs in which retrieval information describing the address of the other VOBUs is described are arranged in the leading VOBU. When special reproducing processing is made, the jump address deciding section 50 of an MPU decides a new address by fetching retrieval information from a read-out navigation pack. An audio decoder section 60 decodes audio data in the VOBUs, holds the data in a holding section 84, and while the VOBUs are retrieved, outputs the holding data. Therefore, sounds are reproduced without interruption.
