Title: Clock selection circuit
Inventor: KAJI TATSUO
IPC: H04Q11/04
Filed: 1993-12-28
Abstract: PURPOSE:To provide a clock selection circuit by which the operation of a digital circuit can be managed without being interrupted at the time of the changeover of a clock, and the reliability of the operation can be improved. CONSTITUTION:In the case of the changeover from a 0 system clock to a l system clock, displacement from an 'L' level to an 'H' level of a 0/1 system select signal is detected by a synchronization de tecting part 101a, a displacement detecting part 102a, the synchronization detecting part 101b and the displacement detecting part 102b synchronously with its own clock for each system. After the displacement of the 0/1 system select signal is detected, in the temporary stop/reset control part 103a of a 0 system, its own system clock '0' being selected at present is turned into a temporary stop state. On the other hand, in the temporary stop/reset control part 103b of a 1 system, its own system clock '1' selected newly is reset synchronously with its own clock.

Title: Pneumatic tire
Inventor: YAMADA SEIJI
IPC: B60C15/00
Filed: 1999-11-29
Abstract: PROBLEM TO BE SOLVED: To minimally restrain an increase of an amount of used rubber, and enhance stability. SOLUTION: Rigidity in the vicinity of a bead part 12 (tire rotating direction) is increased thereby increasing stability in forward/backward direction of the tire since a rubber layer 40 between plies (100% extension modulus is within a range of 2.5 Mpa to 8.0 Mpa and JIS A hardness is 50 to 85 degree) is provided in a parallel part between a main body 20A of a carcass ply 20 and a folded part 20B to thick a gage between plies. When vibration occurs, the rubber layer 40 between plies is deformed by shearing to absorb the vibration, whereby the vibration is easy to stop. As compared with a conventional tire in which an amount of rubber used is increased due to thickening of rubber layer outside a side wall and a carcass inner surface rubber layer, stability is efficiently enhanced by the rubber layer 40 between plies, and increase of the used rubber amount is minimally restrained.
