Title: Hydroxylation of phenol compound
Inventor: MISHIERU KONSUTANTEINI
IPC: B01J31/02
Filed: 1991-10-07
Abstract: PURPOSE: To produce hydroquinone in a high yield by allowing a keto compd. such as benzophenone to exist at the time of hydroxylating a phenolic compd. with H 2 O 2  in the presence of a strong acid.  
     CONSTITUTION: When a phenolic compd. represented by formula I (where each of R and R 0  is H, a 1-4 C alkyl, cyclohexyl or phenyl), especially phenol is hydroxylated with H 2 O 2  in the presence of a strong acid, preferably sulfuric acid, p-toluenesulfonic acid or perchloric acid, a keto compd. represented by formula II (where each of R 1  and R 2  is H or an electron donative group, they may form a keto-contg. ring and each of n 1  and n 2  is 0-3), e.g. benzophenone, 2-methylbenzophenone or fluorenone is allowed to exist in the reaction system. By this method, the amt. of hydroquinone formed can be increased as compared with the amt. of pyrocatechol at the time of hydroxylating phenol.

Abstract: PURPOSE: To reduce the amount of evaporation of liquid helium in a cryostat container and ensure stable operation for a long time by separately independently providing a shield cooling circuit serving to flow a part of the helium gas cooled in a heat stage on the high temperature side of a precooling machine to a shield heat exchanger of the cryostat. CONSTITUTION: A sealed cooling circuit 30 is adapted such that helium gas is supplied from a high stage compressor 3 to a previously cooling machine 4, and a part of the helium gas cooled to about 60 K on a high temperature side heat stage 5 is led to independently flow to a shield heat exchanger 22 of a cryostat C to effectually cool a shield plate 20, and thereafter cold heat is recovered on a tertiary side 11c of a cold heat recovery heat exchanger 11 to raise the gas to ordinary temperature, through which gas is returned to a suction side of the high stage compressor 3 of a compressor unit A to ensure circulation of the helium gas.  Since the amount of the gas flowing through the shield cooling circuit 30 is adjustable, i.e., increased and decreased with an adjustment valve 31, cooling capacity of a first shield heat exchanger 22 of the cryostat C is increased and hence the first shield plate 20 is securely cooled to predetermined temperature (about 80 deg.K).

Abstract: PURPOSE:To obtain a required frequency characteristic by correcting a detection signal of a sensor based on a frequency response characteristic of the sensor and a required frequency response characteristic, and supplying corrected data as command data of an electronic control device for controlling a motorcar. CONSTITUTION:A frequency response characteristic model of a sensor 91 for detecting a condition of a motorcar is previously set in a compensation parameter computation part of a control unit 10. By using the model, a required frequency response characteristic and a response characteristic of the sensor 91, are input to the compensation parameter computation part so as to obtain a required frequency characteristic over a compensation element system. A compensation parameter for setting a compensation means is determined from the required frequency response characteristic and the frequency response characteristic of the sensor 91 by the computation part. Delay of measured data obtained from the sensor 91 is compensated by the compensation means, and the corrected data are output. The corrected data are input to an electronic control device for controlling a motorcar such as a fuel injection control device, and reflected to command data. The required frequency characteristic is thus obtained.

Filed: 1990-10-24
Abstract: PURPOSE:To reduce the adjustment time by applying a test signal to an output side of the balance adjustment circuit so as to eliminate the need for re-adjustment of the balance adjustment circuit even when the test mode is set. CONSTITUTION:The adjustment device is provided with a test signal generator 5 not requiring balance adjustment between channels and 1st and 2nd switches 11, 12 selecting either an output signal of a balance adjustment circuit 6 or an output signal of the test signal generator 5 and outputting the selected output.
