Title: Valve structure of engine exhaust system
Inventor: NAGAI TADASHI
IPC: F01N1/08
Filed: 2001-03-30
Abstract: PROBLEM TO BE SOLVED: To prevent vibration of the valve body of an engine exhaust system due to resonance. SOLUTION: A support member 10, having a tubular part 11, is jointed to the end of a muffler pipe 1, and the support member forms a flange 12 and a support bracket as an valve seat. A valve element 20 is rotatably supported in the support bracket 14 via a hinge shaft 15. For the valve element 20, an arcuate weight 30 is welded to the back of a valve wall 21 along a flange with a circular arc R, apart from the hinge shaft. The end of a spring 16, wound around the hinge shaft is stopped in the back of the valve wall 21, and the other end 19 is stopped in to the support bracket. Since the weight is far from the hinge shaft, the number of vibration of the resonance is reduced effectively by the light weight, and hum in the rotational speed of the engine for regular use is prevented from occurring.

Title: Disk drive
Inventor: HAYASHI TSUNEO
IPC: G11B7/007
Filed: 2001-03-30
Abstract: PROBLEM TO BE SOLVED: To improve reproduction reliability about a drive corresponding to a disk in which a track has a wobble structure. SOLUTION: A first PLL circuit for inputting a wobble signal and reproducing a clock synchronized with a wobble period is provided with a periodic error detection circuit for detecting a periodic error about the inputted signal. Since the wobble signal is obtained by detecting a wobble formed by a fixed period with respect to a track of the disk, the operation of the PLL circuit based on periodic error detection performs pull-in operation so as to synchronize with the wobble period. As a result of adopting such a configuration, the PLL circuit is prevented from being pulled in by an erroneous frequency while being different from a conventional practice in which, for instance, an oscillation frequency of a crystal vibrator is utilized, and a fast pull-in operation can be obtained to that extent.
