A liquid-filled suspension device having an inner cylinder, an outer cylinder, and an elastic member connecting these cylinders to each other. A connecting member is arranged on the cylinder, a closed liquid chamber formed inside at least one of the inner and outer cylinders, a restricted passage formed in the middle portion of the closed liquid chamber, and a flexible membrane member arranged in the closed liquid chamber. An electroviscous liquid is filled in the closed liquid chamber, and two electrode plates arranged in the restricted passage. In this suspension device is used a control device having sensors arranged on these cylinders, and arithmetic decision logic operated by signals from these sensors, and a high-voltage generating circuit operated by signal from the arithmetic decision logic.

A vibration isolator mounted on a support for a vehicle engine or the like which is a vibration source, in which a central limitational passage is formed in a partition wall which divides a fluid chamber filled with a fluid into a pair of small fluid chambers, the central limitational passage providing communication between the pair of small fluid chambers. The central limitational passage can be opened or closed by a valve capable of linearly moving so that the resistance to the fluid flowing through the central limitational passage is changed when vibrations occur. Additional connectable small limitational passages are provided in the valve and partition wall to provide communication between the small fluid chambers when the central limitational passage is closed by the valve. With this structure, vibrations can be absorbed over a wide frequency range.

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.

A damping coefficient control device, for use in a vibration damper of the type which is disposed between a vibration source and a vibration receiving section to be isolated from the vibration of the vibration source and which has a plurality of small liquid chambers charged with an electrorheologic fluid and communicated through an orifice, includes electrodes disposed in the orifice to receive a voltage which is suitably controlled so as to cause a change in the viscosity of the electrorheologic fluid, thereby controlling the damping coefficient provided by the fluid. The damping coefficient control device has sensors for sensing the velocities of the vibration source and the vibration receiving section. When the direction of the velocity of the vibration receiving section is the same as the direction of the relative velocity of the vibration receiving section relative to the vibration source, the voltage applied to the electrodes is controlled such as to increase the damping coefficient provided by the electrorheologic fluid, whereas, when these directions are different, the voltage is controlled such as to decrease the damping coefficient. This arrangement enables the vibrations of different frequencies to be damped without any risk that resonance will occur.

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.

A semiconductor memory device comprises a plurality of memory cells, and each of the memory cells includes a transistor region in which one or more transistors included in the memory cell are formed and a high-resistance element region in a resistor layer overlying the transistor region in which one or more high-resistance elements are formed. The high-resistance element region has a shape different from that of the transistor region and occupies an area not larger than that of the transistor region.

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.

A semiconductor integrated circuit which is of entire microstructure so as to reduce a gate length as to an EPROM formed on a substrate, thereby increasing the quantity of a current flowing between a source and a drain and, on the other hand, a transistor portion other than the EPROM on the same substrate is of structure for weakening the electric field between the source region and the drain region by means of the LDD technique or the like, thereby preventing the occurrence of a breakdown in the channel caused by hot electrons.
