Title: Method for detecting index change point of subcode q channel, and method for recording master disk for optical disk provided with subcode q channel
Inventor: KATO YUICHI
IPC: G11B7/00
Filed: 1999-07-14
Abstract: PROBLEM TO BE SOLVED: To detect an index change point at high speed by finding the start points of respective indexes on respective tracks from a TOC information. SOLUTION: The start address of an index 0 on a track (n) is detected by decreasing an address value for prescribed step width every time from the start address of an index 1 on the track (n) provided from a TOC until a track n-1 and increasing the address value for one frame every time. Next, in order to find out the start address or indexes greater than an index 2 on the track (n), a subcode is read by successively performing access from the start address of the index 0 on the track (n). When the index is changed from 2 to 3, the start address of the index 3 on the track (n) is detected by reading the subcode while successively performing access from an access point in the end part of the index 2 for one frame every time. Thus, the start address of indexes greater than the index 2 on the track (n) is detected.

Filed: 1995-08-04
Abstract: PROBLEM TO BE SOLVED: To small suppress hysteresis of rising/lowering of a pressure in a combustion chamber, while the pressure in the combustion chamber can be high accurately detected by a pressure sensor. SOLUTION: A main unit metal fitting 14 has an insertion cylinder 15 inserted into an insertion hole 6, and no thread is formed in the periphery of this cylinder. As a means for fixing the main unit metal fitting 14 to a cylinder head 4, a flange 17 formed to be opposed to an external diametric direction of a seat part 16 is used. This flange 17 is fixed toward inside a recessed part 5 of the cylinder head 4 by screws 21, and the seat part 16 of the main unit metal fitting 14 presses a gasket 19 and a pressure sensor 3 to a bottom of the recessed part 5. In the case of exploding a mixture in a combustion chamber 1, by preventing exhaust gas from being advanced as in prior art to a fine clearance in a screw fitting part, an in/out flow of gas in the screw fitting part is prevented from being caused, and hysteresis of the pressure sensor 3 is suppressed.  Since pressure rise energy is prevented from being absorbed in the screw fitting part, detecting accuracy of the pressure sensor 3 is improved.
