The present invention provides a reticle container that is equipped with a secondary container which houses the reticle and is housed in the primary container. The secondary container is held within the primary container with shock and vibration isolation members so that the secondary container has multiple degrees of freedom of motion within the primary container. The reticle is secured inside the secondary container such that shock and vibration transmission from the reticle container to the reticle is substantially attenuated.

An upper bush is secured to a bracket of a compressor unit, and a lower bush is abutted against a panel member of a vehicle body through a washer. A coil spring is interposed between the upper and lower bushes. A pipe member is inserted through the upper and lower bushes and the coil spring. A bolt is inserted through the pipe member and screwed into the panel member of the vehicle body. The compressor unit is resiliently supported floatingly by the coil spring. Vibration of the compressor unit is damped by friction generated by sliding contact between the pipe member and raised portions of the upper bush. When the vibration amplitude is large, respective projections of the upper and lower bushes abut against each other to suppress the vibration while absorbing impact.

The invention discloses a periodic-structure vibration isolation device which comprises two panels, multiple vertical rods and multiple oblique rods, wherein the two panels are arranged at intervals; one panel is connected with equipment which needs vibration isolation through a vibration isolator, and the other panel is connected with a mounting base by virtue of a vibration isolator; the multiple vertical rods are arranged in an array and are vertically arranged between the two panels so as to form multiple vibration isolation regions, reinforced rib plates are arranged at connection parts between all vertical rods in each vibration isolation region and the upper and lower panels; one oblique rod is arranged between every two reinforced rib plates which are arranged in opposite angles of each vibration isolation region, and the oblique rods in the two adjacent vibration isolation regions are arranged symmetrically relative to the common vertical rod, so that a vibration isolation structure with periodic arrangement is formed, the band notched characteristic of the periodic structure is formed and effective vibration isolation and noise reduction are realized. The device is capable of not only providing sufficient static rigidity and dynamic rigidity, but also effectively isolating low-frequency narrow-band line spectrums and wide-band vibration transfer which are generated by main and auxiliary mechanical devices and restraining noise radiation caused by vibration transfer.

The invention discloses a distributed optical fiber temperature measurement power cable, which comprises a metal wire armor layer. At least one temperature measurement optical fiber is inserted into armor steel wires arranged in sequence; the temperature measurement optical fiber comprises a temperature measurement fiber core and an optical fiber wrapping layer wrapping the outer side of the temperature measurement fiber core, a heat conduction layer wraps the optical fiber wrapping layer, the periphery of the heat conduction layer is sleeved with metal outer pipes at intervals, and the spacebetween the heat conduction layer and the metal outer pipes is filled with heat conduction filling paste. The heat-conducting filling paste comprises the following components in percentage by weight:18%-20% of a gelatinizing agent, 3%-5% of an oil separation inhibitor, 1%-2% of an antioxidant, 2%-2.5% of a water absorbent, 0.0015%-0.002% of a defoaming agent and the balance of a heat-conducting oil, wherein the shielding layer is formed by wrapping a heat conduction shielding belt, the heat conduction shielding belt comprises a graphite diaphragm, one side surface of the graphite diaphragm isplated with a metal plating layer, and the other side surface of the graphite diaphragm is provided with a heat conduction adhesive layer. The power cable can accurately monitor the operation condition of the cable in real time.
