摘要： A silicone rubber composition comprising an organopolysiloxane and a curing agent is improved by adding a foaming agent in an amount of 0.1 to 10 parts by weight per 100 parts by weight of the organopolysiloxane. The composition is heat curable into silicone rubber films or coatings which are substantially unfoamed and tack-free on a surface.

摘要： An acrylic rubber composition is proposed which is improved in respect of the extrusion-moldability as well as the surface slipperiness of the vulcanized article obtained therefrom. The composition comprises (a) an acrylic rubbery cooplymer which is a copolymer of a (meth)acrylic ester and a coolymerizable organosilicon compound having a silicon-bonded vinyl group in a molecule, (b) a reinforcing filler, (c) a powder of spherical particles having a specified average particle diameter and (d) an organic peroxide as a vulcanizing agent. The composition can be compounded further with a blowing agent to give a foamable rubber composition capable of being vulcanized into a spongy rubber body exhibiting excellent feeling on touch and slipperiness in contact with human skin to be useful, for example, as a material of cosmetic puffs.

摘要： The present invention provides a method and facility for preventing crumbling and powderization of green pellets when producing high strength green pellets using a powder feedstock and using the pellets in a rotary hearth reducing furnace and for efficiently reducing the same. It comprises kneading by a kneader 5 a feedstock of a powder of a fine particle size (20 to 80 wt % having size of not more than 10 μm) including a metal oxide and carbon-bearing powder fed from a feed storage tank 1 and producing green pellets by a pan type pelletizer 7. The green pellets are screened by a pellet screen 9, then dried by a pellet dryer 11 and reduced by firing in a rotary hearth reducing furnace 13. At that time, the green pellets are continuously conveyed to prevent crumbling.

摘要： A sample/hold apparatus includes first, second and third power supply terminals to which first, second and third power supply voltages are applied. The second power supply voltage is an intermediate voltage between are first and third power supply voltages. A sampling switching element is adapted to pass an input voltage at an input terminal therethrough in response to a sample/hold voltage at a sample/hold terminal. A capacitor has a first terminal connected to an output of the sampling switching element and a second terminal connected to the second power supply terminal. A buffer amplifier is adapted to perform an impedance conversion upon a voltage at the first terminal of the capacitor to generate an output voltage at an output terminal. The buffer amplifier is powered by the first and third power supply voltages.
