Patent EP-0308750-A1 (EP)
Inventor: YABUKI YOSHIHARU
IPC: G03C1/61
Filed: 1988-09-09
Abstract: A base precursor in the form of a salt of an organic base with a carboxylic acid is disclosed. The organic base is a diacidic to tetraacidic base which is composed of two to four guanidine moieties and at least one link­ing group for the guanidine moities. The organic base is such a hydrophilic compound that the number of carbon atoms contained in the organic base is not more than six times the number of the guanidine moieties. The linking group is a residue of a hydrocarbon or a heterocyclic ring. The guanidine moiety corresponds to an atomic group formed by removing one or two hydrogen atoms from a compound having the following formula (I):
      wherein each of R¹, R², R³, R⁴ and R⁵ independently is hydrogen, an alkyl group, an alkenyl group, an alkynyl group, a cycloalkyl group, an aralkyl group, an aryl group or a heterocyclic group, each of which may have one or more substituent groups, and any two of R¹, R², R³, R⁴ and R⁵ may be combined together to form a five-membered or six-membered nitrogen-containing heterocyclic ring. A process for formation of an organic base from the base precursor and a light-sensitive material containing the base precursor are also disclosed.

Abstract: A ceramic sintered body comprising TiB₂ as the principal component, 0.5 to 30 wt. % of SiC and 2 to 40 wt. % of ZrO₂. In some cases ZrO₂ includes stabilizers for tetragonal crystal, such as Y₂O₃, MgO or CeO₂. The sintered body has a dense structure where TiB₂, ZrO₂ and SiC unifornly disperse. ZrO₂ is located at the grain boundary of TiB₂, and inhibits the grain growth of TiB₂ as well as improves the strength of the sintered body by binding it to TiB₂ strongly. SiC is located not only at the grain boundary but also on the inside of both grains. Since the contract of SiC during cooling process of the sintered body is less than TiB₂ and ZrO₂, compressive stress is produced in SiC and around thereof. The sintered body is remarkably strengthened by the residual compressive stress, and simultaneously, the high fracture toughness is also achieved.

Abstract: A device for the contactless detection of overheated parts, such as, for example, axle bearings, brakes, wheel tyres, on passing rail vehicles is described. The device has a sensor (2), which is provided with an infrared optical system, and an infrared detector (12) with subsequent electronics and evaluation circuit (15) connected downstream. The device is characterised in that the sensor with the infrared optical system (3) on the one hand and the infrared detector (12) with subsequent electronics on the other are arranged spatially separated from one another and in that in order to pass on the infrared beams from the optical system to the detector at least one fibre which guides the infrared light in the wavelength range of approximately 2-12 micrometers is provided. In a preferred embodiment, a plurality of fibres (16, 17, 18) which run parallel to one another are used, the sensor-side light injection surfaces of which are directed towards different heat targets and whose detector-side light emergence surfaces have a scanner element (19, 20) opposite them which successively guides the beams which emerge from these emergence surfaces onto the detector in a constantly repeating fashion. An assignment electronic system (25) connected downstream receives an item of information relating to the current position of the scanner element (19, 20) and assigns the individual temperature-analogous electrical signals unambiguously to the respective fibres (16, 17, 18). <IMAGE>
