Title: Production of racemic trifluorolactic acids
Inventor: KATAGIRI TOSHIMASA
IPC: C07C69/675
Filed: 1992-06-18
Abstract: PURPOSE:To easily produce a racemic trifluorolactic acid necessary for the selective production of an enantiomer of a trifluorolactic acid useful as a synthetic raw material for physiologically active substance, functional organic compound, etc. CONSTITUTION:A racemic trifluorolactic acid is produced by reacting (A) an optically active isomer of a trifluorolactic acid of formula (R is substituted or unsubstituted alkyl) having asymmetric center on methine carbon atom bonded with trifluoromethyl group and hydroxyl group with (B) a basic compound (preferably an equivalent mixture of a trialkylphosphine and an azodicarbonic acid ester compound or a bicyclic amidine compound). The progress of the racemization reaction can be promoted and the yield of the product can be improved by adding a neutral proton-donor (e.g. primary amine or p- toluenesulfonylamide) to the reaction system. The present process can produce a relatively large quantity of an optically active isomer of trifluorolactic acid or its derivative having reverse optical activity, which has been difficult to synthesize.

Abstract: PURPOSE:To reflect one split piece of luminous flux odd times and the other split piece of luminous flux no time or even times, to emit them from an optical multiplexing means, and to remove a shift in the position of the light beam from a light source and variation in its traveling direction optically by guiding the reflected light and transmitted light of incident luminous flux by split light guiding means which are equal in optical path length from the splitting of the two pieces of luminous flux to their multiplexing. CONSTITUTION:A luminous flux optical means consisting of a 1st beam splitter 1 splits the incident luminous flux L0 into the reflected light and transmitted light and a 2nd beam splitter 2 as a luminous flux multiplexing optical means reflects one of two split pieces of luminous flux and transmits the other to multiplex both of them. Further, the split luminous flux guiding means consisting of reflecting mirrors 3-7 reflect the two split pieces of luminous flux and guide them to the multiplexing optical means so that the optical paths from the splitting to the multiplexing are equal in length. Then the number of times of reflection along an incidence plane including the two split pieces of luminous flux is odd as to one split piece of luminous flux and zero or even as to the other.

Title: Turbine control device
Inventor: INADA HIROSHI
IPC: G05B11/36
Filed: 1997-07-09
Abstract: PROBLEM TO BE SOLVED: To stably control the extraction pressure of a turbine by estimating a dynamic characteristic of a process on the turbine control device side in case of a change in the dynamic characteristic on the process side, determining a parameter of a variable pressure controller by a control constant determining part on the basis of the estimated result, and controlling the pressure according to the parameter. SOLUTION: In a turbine control device, a process identifying part 18 estimates a dynamic characteristic (i) of a process from an extraction control valve opening command (h) outputted from an allocation ratio computing element 7 and extraction pressure actually obtained from a turbine. A control constant determining part 19 determines a pressure control constant, that is, a control parameter (j) from the dynamic characteristic (i). According to the control parameter (j), a variable pressure controller 20 adjusts a pressure control signal (f) so that the extraction pressure becomes the set pressure, and outputs it to the allocation ratio computing element 7. Accordingly, even in case there is a characteristic change on the process side, the pressure set value of the variable pressure controller 20 can be immediately adjusted by feedback control so as to be able to stably control the extraction pressure of the turbine.
