Title: Antirattler
Inventor: SUZUKI TOSHIHIRO
IPC: B60K5/12
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To slowly deform an elastic body for inputting of load from the start to the end by bringing the elastic body into pressure-contact with an inner face of an outer cylinder on both sides on an x-axis which crosses a y-axis orthogonally and bringing it in contact with the inner face of the outer cylinder on both sides on the y-axis without compressing it. SOLUTION: An elastic body 3 with inner cylinder 1 is press-fitted into an outer cylinder 2 having a non-circular cross section. The inner cylinder 1 is, for example, attached to an engine side, and a nut 5 of a bracket 4 is attached to a car body side to form an antirattler. When the x-axis and the y-axis which pass the center of the inner cylinder 1 and cross orthogonally and mutually are assumed, the elastic body 3 is in pressure-contact with an inner face of the outer cylinder 2 on both sides of the x-axis. Elastic bodies 3A, 3B positioned on both sides of the y-axis are in contact with the inner face of the outer cylinder 2 without being compressed. Since the elastic body 3A on an upper face side or the elastic body 3B on a lower face side are gradually compressed for inputting of load, they are slowly displaced.  By changing a width and a thickness of the elastic bodies 3A, 3B, it is possible to adjust static spring constant and dynamic spring constant of them as the antirattler.

Abstract: PURPOSE:To measure a laser beam output peak value with a high accuracy even at the times of CW oscillation and pulse oscillation by holding a maximum value in a predetermined period of a laser beam output, and detecting the peak value of the beam based on the held value or the detected laser beam output. CONSTITUTION:A peak holding circuit 6 holds a maximum value of a signal for a period from the rise of the output of a pulse generator 3 to the next rise.
