摘要:
3-(3,4-Dimethoxyphenyl)propyltrichlorosilane, which in a new material, was disclosed together with some ways to synthesize it. A usefulness thereof was illustrated by synthesizing polysilazane using the above new material and applying the polysilazane to a steel plate as a protective coat.
摘要:
N-Methyl-N-trimethylsilyl trifluoroacetamide can be synthesized by the reaction of N-methyl trifluoroacetamide and, N,O-bis(trimethylsilyl) acetamide at 40.degree.-130.degree. C. followed by fractionating distillation. The method is advantageous in respect of the absence of the step of filtration for the removal of the by-product salt and non-use of any corrosive reactant in comparison with conventional methods.

摘要:
In an audiovisual system in which a source device and a television are connected via an AV amplifier, even when the AV amplifier is placed in a “Power Supply Standby State”, video/audio signals outputted from the source device can be viewed/listened to on the television without changing the wiring connections between the devices.An AV amplifier (100) is provided with a data storing means (106) used for indicating a signal reproduction ability to a source device (200). During a “Power Supply Standby State” of the AV amplifier (100), the content of data that is saved in the data storing means (106) and indicates an audio signal reproduction ability is rewritten into data that indicates not the reproduction ability of the AV amplifier (100), but the signal reproduction ability of a television (300), thereby producing a state that is equivalent to a state in which the source device (200) and the television (300) are directly connected.

摘要:
Silicone compositions comprising an organopolysiloxane composition and an organic compound capable of coordination with metals are described. Since the organic compound is preferentially adsorbed on a metal surface, the composition is particularly suitable for use in electric or electronic parts to prevent contact failure. A more specific embodiment comprises a diorganopolysiloxane of the average unit formula, R.sub.a SiO.sub.(4-a)/2, wherein each R independently represents an unsubstituted or substituted monovalent hydrocarbon group, and a is a value of from 1.90 to 2.05, a filler, an alkoxysilane or its hydrolyzate, a silylation catalyst made of an organic silicon compound having at least one specific type of group, an organic tin compound, another organosilicon compound capable of reaction with an alcohol in order to stabilize the composition, and an organic compound capable of coordination with metals.
