Title: Production of isocyanate
Inventor: FUKUOKA SHINSUKE
IPC: B01J27/24
Filed: 1988-02-12
Abstract: PURPOSE:To suppress formation of high-boiling by-products and obtain a compound useful as a raw material for polyurethanes or carbamate based agricultural chemicals in good yield with ready separation of the product from a catalyst, by subjecting carbamic acid esters to thermal decomposition reaction in the presence of a catalyst. CONSTITUTION:Carbamic acid esters are subjected to thermal decomposition reaction in the presence of one or two or more catalysts selected from carbides or nitrides of vanadium and chromium family elements of the periodic table. The reaction is carried out in a solvent (e.g. bromonaphthalene) inert to isocyanates without dissolving the catalyst at 100-350 deg.C for several min - several tens of hr to afford the aimed substance. Since the catalyst is insoluble in the reaction solution, separation thereof from the product is readily carried out and the method is particularly advantageous to production of high-boiling isocyanates which are hardly distilled by distillation.

Title: Noncontact temperature measuring sensor
Inventor: MASUTANI TAKESHI
IPC: A61B5/01
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To obtain a sharp beam by a method wherein a light guide device having a taper-shaped inner face is arranged between an optical lens and a chipper and stray light is reduced. SOLUTION: A chopper 3 is arranged between an optical lens 2 and an infrared sensor 1, and a light guide device 5 which has a taper-shaped inner face is installed between the optical lens 2 and the chopper 3. Infrared rays which are radiated from an object to be measured are narrowed down by the optical lens 2 which uses a silicon diffraction-type plano lens so as to be incident on the infrared sensor 1. A beam which is condensed on the infrared sensor 1 from the optical lens 2 is shut off by the chopper 3 at constant intervals, and it can be measured continuously by a pyroelectric infrared sensor. An incident beam which has an angle is reflected by the tapered light guide device 5 so as to change its angle gradually, it does not reach the infrared sensor 1, and it does not becomes stray light.  Since the stray light is reduced, it is possible to obtain an effect to invalidate the beam which is incident on the optical lens 2 but which is deviated from an optical axis, and the visual-field characteristic of the optical lens can be improved.
