摘要:
According to the present invention there is provided a heat mode imaging element for making a lithographic printing plate having on a lithographic base with a hydrophilic surface a first layer including a polymer, soluble in an aqueous alkaline solution and a top layer on the same side of the lithographic base as the first layer which top layer is unpenetrable for or insoluble in an alkaline developer containing SiO.sub.2 in the form of silicates; characterized in that said first layer and said top layer comprise a compound capable of converting IR-light into heat.
摘要:
A device and method for controlling the interior temperature in the passenger compartment of a motor vehicle, in which the actual interior temperature detected by a radiation sensor is fed to a control loop which sets the interior temperature as a function of the measured temperature and a prescribed temperature. In an arrangement for controlling the interior temperature in which the noise disturbance from the fan motor is eliminated and reliable control of the interior temperature is ensured nonetheless, the radiation sensor is arranged on a printed circuit board which carries the control loop, such that a sensitive surface of the radiation sensor detects the thermal radiation which impinges on an outer surface, facing the vehicle interior, of a housing enclosing the printed circuit board.
摘要:
The invention relates to a method for preparation of aminoaryl- or aminoheteroarylboronic acids and esters and salts thereof in which an optionally substituted aminoaryl or aminoheteroaryl compound is protected at its nitrogen site via condensation with a carbonyl compound, subsequently metalated and converted with a suitable boron compound. Depending on the subsequent work-up and removal of the protective group, the corresponding boronic acid, the anhydride or the boronic acid ester thereof is obtained
