Abstract: PURPOSE: To simply and exactly control the vulcanization degree of a tire by a method in which the vulcanization of tire is stopped at a time when the total product of vulcanization degrees obtained from the temperatures of tire which are estimated on the basis of the temperatures of unvulcanized tire measured before a vulcanizing pan is closed reaches a given value.
CONSTITUTION: An unvulcanized tire is packed in a vulcanizing pan. Before the vulcanizing pan is closed, the temperature of the unvulcanized tire is measured to obtain an eary period temperature T
o . On the basis of the temperature T
o , the temperature of the tire being vulcanized is estimated, and from the estimated temperature, the total product S of vulcanization degrees from the starting time t
o of vulcanization to the time t
1 is obtained by the Arrhenius' equation (where E is activation energy, R is gas constant, T is tire temperature, T
o is reference temperature, and t is passed time period). At a time when the total product S of the vulcanization degrees obtained in this way reaches a set value, the vulcanization is completed.

Abstract: PURPOSE:To simplify and miniaturize the structure of a vibration damping equipment by enclosing a gas or a fluid, which can be liquidized, in a sealed room and setting installing members on both a contracted-passage-constituting- member-side and a face-plate-side of the equipment, thereby effectively absorbing high frequency microvibration. CONSTITUTION:One sealed room 6 is formed in such a manner that folding parts 1a, 2a of both flexible film bodies 1, 2 face to each other. Inside this sealed room 6, both face plates 4, 5 of the room 6 are connected to each other by means of a cylindrical rigid member 7. In the sealed room 6, air or other gas or water, an antifreezing solution, an electroviscous fluid, a magnetic fluid and a fluid 8, which can be liquidized are enclosed. In addition, installing members 11, 12 are set on the face plate 4 and on a contracted-passage- constituting-member 3. Owing to a sliding guide 13, sliding motion of a rigid member 7 is smoothed, and moreover it is unnecessary to consider the sealing property to the enclosed fluid 8. Therefore, frictional force of the rigid member 7 to the sliding guide 13 can sufficiently be made small.

Abstract: PURPOSE:To absorb high-frequency low amplitude vibration in a simple structure by storing an elastic body absorbing high-frequency low-amplitude vibration in a free piston separating a liquid chamber from a gas chamber. CONSTITUTION:A free piston 16 is of a hollow structure and provided with an opening 19 connected to a liquid chamber 14. An elastic body 20 comprising a plurality of hollow spherical or cylindrical rubber or rubber elastic bodies is stored in the free piston. The elastic body 20 is adapted to decrease its volume substantially rectilinearly at the contraction stroke of a rod 15 until the pressure in the liquid chamber and in its turn the pressure in the free piston 16 amounts to a fixed pressure P and to keep its volume substantially constant for the pressure more than a fixed value. Thus, high-frequency low amplitude vibration can be absorded effectively by deformation of the elastic body 20.
