    摘要: Vinylphenol-type polymers are useful materials and are used in many fields such as photoresist, packaging material for IC, printed circuit board, lense, etc. When the polymers are used in an electronic field such as photoresist and packaging material for IC, it is desired to reduce metal concentration in the polymer in the order of ppb units. A simple and effective process for removing metals from vinylphenol-type polymers is disclosed. The process comprises passing an organic solvent solution of a vinylphenol-type polymer either through (a) a filter containing an ion exchange material and/or a chelate-forming material and generating a zeta (.zeta.) potential by a cationic charge modifying agent or through (b) (i) a filter containing an ion exchange material and/or a chelate-forming material and (ii) a filter generating a zeta (.zeta.) potential by a cationic charge modifying agent.

    摘要: A vibration isolating apparatus is disclosed which comprises an inner tube and an outer tube disposed in a parallel axis state to each other and an elastic member stretched therebetween, the elastic member being provided with a pair of liquid chambers disposed in the interior thereof at opposite sides through the inner tube. These liquid chambers communicate with each other through a restricted passage. The elastic member is provided with a pair of cavities on opposite outer sides of the inner tube. The cavities absorb relative displacement between the inner tube and the outer tube. When an amount of absorption becomes a predetermined amount, a compressing force is applied to the liquid chambers.

    摘要: An anti-vibration apparatus includes an expandable liquid chamber, an electrorheologic fluid contained in the liquid chamber, a partition wall for separating the liquid chamber into a plurality of small liquid chambers, and an orifice communicating the small liquid chambers. The orifice comprises an elongated orifice, within which electrodes are disposed to pass a current through the electrorheologic fluid. Therefore, the viscosity of the electrorheologic fluid contained in the orifice can be changed, so as to adjust the resistance to the flow through the orifice of the fluid.

    摘要: A vibration absorbing apparatus disposed between a vibration source and a vibration receiving portion and having a tubular member which is formed such as to pass through an expandable liquid chamber and which is attached to one of the vibration source and the vibration receiving portion. A partitioning plate is secured to the outer periphery of the tubular member such as to divide the liquid chamber into a plurality of liquid sub-chambers. The liquid sub-chambers communicate with each other via an orifice. Accordingly, even if the direction in which vibration acts upon the apparatus is shifted, it is possible to prevent the occurrence of "pinch" between the partitioning plate and the tubular member.

    摘要: An exhaust gas recirculation system for an internal combustion engine employs an exhaust gas recirculation control valve in a passageway connecting the engine exhaust passage to the engine intake passage downstream from the throttle valve. The intake passage also provides a choke valve and a carburetor venturi section between the valves. An air conduit having an air control valve therein connects the intake passage between the throttle valve and the choke valve to the intake passage downstream from the throttle valve. Vacuum responsive actuators are provided for each of the control valves and they are operated by vacuum pressure regulated by a regulating valve, which is itself responsive to differential pressure between vacuum intensity in the intake passage upstream from said throttle valve and modified atmospheric pressure. The modified atmospheric pressure is obtained downstream of a restriction in the air conduit. Closing of the choke valve on a cold start of the engine causes high vacuum intake to the air conduit, reducing the exhaust gas recirculation through the exhaust gas recirculation control valve.
