Title: Infrared detector
IPC: G01J5/12
Filed: 1992-03-11
Abstract: PURPOSE:To detect a detective object stably even in a static state without receiving any effect of ambient temperature change by detecting infrared rays past two infrared filters with each of different infrared wavelength transmission bands with respective infrared detecting elements. CONSTITUTION:Two infrared detecting elements 3 and 4 consisting of a thermopile element each are provided with different infrared wavelength transmission bands, detecting infrared rays past two interference filters 1 and 2 mounted with a dielectric multilayer film on a silicon substrate are detected. These elements 3, 4 are clamped to a heat equilibrium plate 5 so as to have almost the same detecting area. In addition, since the filters 1, 2 show each of different infrared transmitting characteristics in the specified wavelength range, a different part is produced in each output of these elements 3, 4 only at a time when infrared rays in this range were incident. If a human body is in the detection area, such a voltage output as larger than the specified level one is produced in an interval between both these outputs of the detecting elements 3 and 4 due to something a difference in the infrared wavelength transmitting bands of these filters 1 and 2. This voltage output is amplified (6) and inputted into a voltage comparator 8, thus the existent human body is detected.

Title: Manufacture of 1,2-diacyl-sn-glycerine
Inventor: PAABUO KEE JIEE KINNUNEN
IPC: C07C69/616
Filed: 1981-04-09
Abstract: The object of the present invention is a novel and simple process forthe production of 1,2-diacyl-sn-glycerols, wherein the acyl groups may be the same or different. According to the invention D-mannitol is reacted with benzene boronic acid or a derivative thereof to form a D-mannitol- monobenzeneboronate which compound is acylated either to form, after removal of the benzeneboronate protective group, a 1,2,5,6-tetraacyl-D-mannitol with four identical acyl groups, or is acylated selectively in two stages, by first acylating the 1,6-hydroxy groups of the boronate protected D-mannitol to form, after removal of the boronate protection, a 1,6-diacyl-D-mannitol, which then is repeatedly reacted with a benzene boronic acid or a derivative thereof and then acylated in the 2-and 5-positions. After removal of the boronate protective group, the tetra-acylated D-mannitol obtained either in the one-stage or two-stage process is split by oxidation to form a 1,2-diacyl-glyceraldehyde which in turn is reduced to the corresponding 1,2-diacyl-sn-glycerol. By means of the invention it is thus possible to prepare 1,2-diacyl-sn-glycerols in which the acyl groups can be the same or different.
