Abstract:
A method for fabricating a glass substrate containing SiO2 as a main ingredient thereof for an information recording medium which ensures removal of abrasive or foreign mater adhered to the glass substrate without complicating a cleaning step, involves, after a polishing step, keeping the surface of the glass substrate in contact with a liquid having a Si element elution in a range from 100 to 10 000 ppb/mm2 before a scrub-cleaning step.

Abstract:
A method for cleaning a glass substrate which ensures removal of abrasive and other foreign matter without making a cleaning step complicated involves cleaning the glass substrate by scrubbing using two or more types of cleaning liquid having different Si element elution abilities. The cleaning liquid having the highest Si element elution is used first, and the cleaning liquid having the lowest Si element elution is used last.
Abstract:
A reproduction route composed of a still image section and a motion image section is recorded on a recordable DVD. A drive device (93) reads picture data from the DVD-RAM. An MPEG decoder (95) decodes and displays the read picture data. By referring to cell information, the judgment is performed as to whether the read picture data belongs to the still image section or the motion image data. If the read picture data belongs to the still image section, the next picture data is read out after a predetermined wait time.
Abstract:
A multimedia optical disc for recording main video data which is composed of sets of frame data that is processed beforehand to allow compatibility with displays of a plurality of aspect ratios. The disc has a stream area storing streams made up of the main video data and a plurality of sets of sub-picture data, with each set of sub-picture data including a set of tel-op data and a set of coordinate information showing a display position of the set of tel-op data. The disc also includes a control area storing a plurality of pairings of a set of display mode information and a set of sub-picture indicating information. Each set of display mode information shows a species of display method according to which the frame data is to be processed for a case when the frame data decoded from the main video data is displayed at one of the plurality of aspect ratios. Each set of sub-picture indicating information shows a set of sub-picture data, out of the plurality of sets of sub-picture data in a same stream as the main video data, which includes a set of coordinate information which coincides with the species of display method shown by the display mode information.
Abstract:
A multimedia optical disc on which a variety of types of video titles are recorded and which enables a reproduction apparatus to instantly distinguish whether emulated AV functions may be performed for any of the titles. The multimedia optical disc includes a manager area which stores playback type information corresponding to the management information for each video title, with the playback type information including a first flag showing whether the present video title is expressed using one or a plurality of sets of route information and a second flag showing whether a title is expressed using any branch information.

Abstract:
A capacity detection type sensor element includes a rectangular vibrating plate, a flat back electrode which are provided opposedly with each other, and fixing portions which are provided adjoining to the vibrating plate, and has a predetermined length A of edge at a side adjoining to the vibrating plate. The back electrode is held by the fixing portions in a state that space is provided between the back electrode and the vibrating plate. Outer edges of the back electrode which are not held by the adjoining fixing portions, are straight lines and the straight lines define an octagonal shape as a whole.
Abstract:
An optical disc includes a data area for recording a plurality of video segments and an index area for recording original type chain information and user-defined type chain information. The original type chain information defines an original type chain including first ones of the video segments by describing a reproduction order of the first video segments. The user-defined type chain information defines a user-defined type chain including second ones of the video segments by describing a reproduction order of the second video segments. The first video segments are positioned in the data area in the reproduction order of the first video segments whereas the second video segments are positioned in the data area independently of the reproduction order of the second video segments.
Abstract:
A sound detecting mechanism is provided which forms a diaphragm with a required thickness and yet restraining distortion of the diaphragm to provide high sensitivity. The sound detecting mechanism comprises a pair of electrodes forming a capacitor on a substrate A in which one of the electrodes is a back electrode C forming perforations Ca therein corresponding to acoustic holes and the other of the electrodes is a diaphragm B. A silicon nitride film 303 is provided on the side adjacent a base of the substrate A with respect to a membrane acting as the diaphragm B formed on the substrate A.
