Title: Method of preparing oligomer mixture from alpha, omega-diolefin and biodegradable base oil comprising same
Inventor: EMANUERU FUIORITAKISU
IPC: C07C2/38
Filed: 1996-03-06
Abstract: PROBLEM TO BE SOLVED: To attain a narrow distribution of the degree of oligomerization by using as a starting material a monomer/dimer/trimer mixture obtained by reacting an α,ω-diolefin in the presence of an organoaluminum compound.  
     SOLUTION: An organoaluminum compound catalyst of 2-4 mol is added to an α,ω-diolefin, and the mixture is reacted in at least two successive stages at 180-210°C and a catalyst concentration of 0.10-0.16 (kmol/m 3 )/hr. The reaction products obtained in the reaction stages are separated into a first ingredient comprising at least 95 wt.% α,ω-diolefin monomer and dimer and at least 60 wt.% trimer thereof and a second ingredient comprising the tetramer and higher oligomers. 60-80% of the first ingredient is used as a starting material so as to keep the total amount of terminal double bonds approximately constant in each stage. Thus, a fresh monomer is used in a reduced amount, and the catalyst amount is increased to a value larger by up to 20 wt.% based on that in the preceding stage.

Inventor: TOMITA FUMIO
IPC: G01N21/359
Filed: 1998-02-13
Abstract: PROBLEM TO BE SOLVED: To obtain a technique in which a raw tea leaf is irradiated with near-infrared rays, in which a component contained in the raw tea leaf is specified on the basis of the attenuation of a specific frequency component computed by measuring their reflected light, whose measuring accuracy is increased and which can be applied actually to a tea processing factory. SOLUTION: In an analytical method, dispersed samples are irradiated with near-infrared rays, the near-infrared rays which are reflected from the samples are measured, and a component contained in the samples is specified on the basis of the attenuation amount of a specific wavelength component. At this time, the area of the samples, in a dispersed state, which are irradiated with the near-infrared rays is set at 50 times or higher the area on one side of a sample single body. Regarding a sample such as a tea leaf or the like in which the surface and the rear of the leaf are different, in which a stem or the like is different and in which a component distribution is different, its component can be analyzed with a very small measuring error in such a way that a pretreatment such as a cutting treatment or the like or a refilling operation into a cell 40 is not required.

Title: Tunnel freezer
Inventor: JIEREMII POORU MIRAA
IPC: F25D3/11
Filed: 1995-02-14
Abstract: PURPOSE: To increase the heat transfer rate of a conventional tunnel freezer in the vicinity of a turbulence inducing fan. CONSTITUTION: A turbulence inducing fan 111 blows cold gaseous nitrogen through ducts 112 disposed to either side of a conveyor 105 carrying product to be frozen through a freezing tunnel 101. The cold gaseous nitrogen is deflected downwardly onto product on the conveyor 105 by a baffler 113 having, in cross section, the form of cusp. The cold gaseous nitrogen forms two counter- rotating vortex. The cold gaseous nitrogen travels across the product and then passes into an intake cowl 110 primarily via inlets 114, 115 disposed adjacent both edges of the conveyor 105. The intake cowl 110 collects the cold gaseous nitrogen which is sucked into the intake of the turbulence inducing fan 111. This arrangement provides excellent heat transfer to the product being frozen.

Abstract: PURPOSE:To detect surely a one-phase ground-fault accident even when a system is operated with a low frequency by controlling the set value of a protective relay through a physical quantity detector which detects a physical quantity proportional to the frequency of a power system. CONSTITUTION:The output from a variable voltage and variable frequency power supply device 2 is impressed to an AC motor 4 of a load of the power system through an output transformer 3.
