IPC: G06F1/00
Filed: 1999-10-15
Abstract: PROBLEM TO BE SOLVED: To make a access right decision while an access control list does not have repetitive access control element in access control using the access control list. SOLUTION: The illustrated table of access common information is arranged ad when an access requester accesses resource information as an object to be requested, the access requester and information on access operation to be requested are compared with access control information given to the information resource to be requested to decide the access right; when it is decided that the access right is not available, it is decided whether or not the table contains access common information regarding the access requester requesting the access right decision making and when so, the access common information on the user (e.g. K1) is compared with the access control information.  Then when a group name (e.g. 1st department) below the group (development department) that the user (K1) belongs to is found in the access control information, the access right is so decided that the user (K1) has the right to access the object information resource.

Title: Production of elliptic core constant polarization optical fiber
Inventor: KAWAKAMI NOBORU
IPC: C03B37/012
Filed: 1985-12-25
Abstract: PURPOSE:The core layer is deposited on the inner wall of a quartz tube by the MCVD method and only specific part in the peripheral direction of the core layer is collapsed by the vapor-phase etching to produce the titled optical fiber with well controlled ellipticity and high reproducibility. CONSTITUTION:The clad layer 12 (SiO2-F-P2O5 layer) is deposited on the inner surface of the quartz tube 11 by the MVCD method, and the core layer 13 (SiO2-GeO2 layer) is formed on the inner wall of the clad layer 12. Then, the quartz tube 11 is heated with a couple of burners 14, 15 from both sides of the cross section to form the heating zones symmetrically to the center axis of the tube 11 and the couple of the burners 14, 15 are allowed to move along the tube axis to move the heat zone in the axis direction. Simultaneously, SF6 gas is allowed to flow in the quartz tube 11 to selectively remove the core layer 13 at two places in the peripheral direction. Then, the quartz tube 11 is collapsed to density to give the ellipsoidal core layer 13, because the core layer 13 is not uniform in its thickness in the peripheral direction. The resultant preform is melt-drawn to produce the elliptic core constant polarization optical fiber of high accuracy in high reproducibility.

IPC: H04L1/00
Filed: 1993-11-25
Abstract: PURPOSE:To reduce the number of expensive memory circuits. CONSTITUTION:When a transmitter applies interleaving to a signal subject to error correction coding, the transmitter interleaves data strings S1, S2 corresponding to a 1st path signal with a depth D1 and interleaves data strings S3, S4 corresponding to a 2nd path signal with a depth D2 deeper than the depth D1. An interleave control circuit 51 makes control so that four interleavers 31, 32, 23, 24 are operated synchronously with each other. The interleaved data string is subject to quadrature amplitude modulation by a modulator 12. A demodulator 13 of a receiver demodulates the signal and uses de-interleavers 33, 34, 27, 28 to de-interleave the signal by a reverse procedure to that of the transmitter and corrects errors.

Abstract: PROBLEM TO BE SOLVED: To reduce a drawing load of a magnetic tape and to keep its tension by making a sliding lever provided with brakes to be in contact with cylindrical projections of reel bases give optimum rotational resistance to both reel bases at the time of drawing the tape. SOLUTION: Brake shoes 2 and 3 at the tips of brake levers 1a and 1b of the sliding lever 1, which are elastically deformed in the sliding direction are brought into contact with outer peripheries of the projecting parts 4a and 4b. The lever 1 is reversibly slid with an engagement pin 8 engaged with a cam groove 7 of a cam gear 6 to be turned by a motor 9, while the magnetic tape 12 is drawn out by the gear 6 with a tape drawing mechanism 13. The groove 7 is continuously changed in direction, so that when the lever is moved in the direction of D or E, elastic deforming amts. of the levers 1a and 1b are increased or decreased, and hence rotational resistance of both reel bases is increased or decreased.  Thus, the optimum rotational resistance is obtained for the reel bases, and the operational load of the mechanism 13 is reduced, and then the tension of the tape 12 can optimally be maintained.
