The object of the invention is to provide a chamber for a heating press which can cope well with the height change of a composite material article. In a chamber for a heating press, upper and lower metal flanges are provided between upper and lower press heating plates and an intrusion part is further formed in the lower metal flange. This intrusion part is intruded into the upper metal flange and the gap between the intrusion part and the upper metal flange is sealed by a packing having a lip.

A behavior monitoring system for a rotary body is capable of monitoring displacement of the rotary body in a plurality of directions. The behavior monitoring system comprises an inclined surface formed on the rotary body and extending in oblique to a rotational axis, and a sensor means for detecting displacement of said inclined surface.

System for monitoring behavior of rotary body

A method for predicting abnormality of a mechanical seal comprises detecting a displacement in the radial direction of a slidable ring of a mechanical seal and predicting abnormality of the mechanical seal from the displacement detected which represents the extent of adhesion of the slidable ring against the rotary shaft.

Method for predicting abnormality of mechanical seal and apparatus for

A mechanial seal having a split seal ring which is covered by a support ring over the outer face with a predetermined gap and is fastened in a circular shape by a O ring inserted in the predetermined gap. The split seal ring is easily assembled by a tool which includes a split ring body. The split ring body has a basic inner face contacting to a surface of a rotary shaft, an end face contacting to the end face of the split seal ring an a projection for inserting the O ring into the gap.

Mechanical seal including a split seal ring

The present invention relates to a fluid agitator which may stir fluid in a closed space without leakage of the fluid. The fluid agitator has a motive means and a bearing means installed in the closed space. In the fluid agitator employing a electric motor as the motive means, only the stator coil of the motor which is weak in its resistance against high temperatures and humid atmosphere is sealed in a sealing chamber. The sealing chamber may be provided with a cooling device to cool the inside thereof. The driving shaft of the motor is supported by a bearing having resistance to high temperatures and high humidity and is provided with an agitating blade. In the fluid agitator employing a turbine system as the motive means, a turbine chamber and a turbine blade are set in the closed space. A fluid supply is furnished to introduce fluid into the turbine chamber from outside of the closed space for driving and rotating the turbine blade. The turbine blade is connected to an agitating blade through a rotation transmission.
