摘要:
The invention provides an RTV organopolysiloxane composition comprising (A) a terminally di- or trifunctional organopolysiloxane, (B) an alkoxysilane, (C) calcium carbonate surface treated with a carboxylic acid having a melting point of at least 100.degree. C., and (D) a condensation catalyst. The composition cures into a cured product capable of forming a durably thermoresistant and water immersion-resistant bond to substrates such as surface treated aluminum members, fluoro-resin coated steel strips and acrylic resin electrodeposited steel strips.

Replicas are molded by curing a photo-curable liquid silicone rubber composition to form a transparent mother mold having a cavity corresponding to the outer contour of a master model, casting a photo-curable liquid resin into the mold cavity, and irradiating light to the liquid resin through the mold wall. Replicas can be fabricated by simple steps and within a short time.
摘要:
An organopolysiloxane composition comprising (A) an organopolysiloxane, (B) a silane compound having at least two hydrolyzable groups or a partial hydrolyzate thereof, and (C) the addition reaction product between a vinyl group-bearing bisphenol A skeleton compound and an organoxy group-bearing silicon compound is curable at room temperature to a variety of resins including PBT, HIPS and acrylic resins.
摘要:
A photo-curable liquid silicone rubber composition is curable upon exposure to light into a cured product having a Shore A hardness of 20 to 60 and a light transmittance of at least 10% at a wall gage of 10 mm. The composition is suitable for forming a transparent templating mother mold which allows a photo-curable liquid resin cast therein to be cured with light transmitted by the mold wall.

摘要:
A receiving apparatus includes a variable gain unit to change between a first gain and a smaller second gain, and to amplify a received signal to obtain an amplified signal; a comparator to compare a power of the amplified signal with a reference value; and a controller to set a gain to the first gain while in a standby state, to reset a gain to a third gain between the first and second gains if in a standby state the power of the received signal is larger than the reference value, and then to set a gain to the first gain and return to the standby state if the power is equal to or lower than the reference value, or if not, to a fourth gain between the first and third gains.

A starting apparatus includes: a storage unit storing an identifier; a rectifying unit rectifying a reception signal; a generating unit comparing the reception signal rectified in the rectifying unit to a reference signal and generating a digital signal from the reception signal; a judging unit judging whether or not the digital signal contains information of the identifier; a reference changing unit changing the reference signal when the judging unit judges that the reception signal does not contain information of the identifier; and a start instructing unit instructing start of an electric appliance when the judging unit judges that the reception signal contains information of the identifier.
摘要:
An RTV organopolysiloxane composition is provided comprising (A) a diorganopolysiloxane capped at both ends of its molecular chain with hydroxysilyl, alkoxysilyl or alkoxyalkoxysilyl and having a viscosity of 20-1,000,000 mPa-s at 25° C., (B) a bis(alkoxysilylalkyl)disiloxane compound, and (C) a curing catalyst. The composition is fast curable into a silicone rubber which establishes a firm adhesion to substrates with an active surface such as float glass and maintains the adhesion even in a harsh environment as immersed in hot water over a long term.
