Title: Enantiomers of 2-tetrahydrofuran derivatives intermediates therefor and their preparation
Inventor: ESTERMANN HEINRICH
IPC: A61P37/00
Filed: 1996-06-27
Abstract: The compound of formula I <CHEM> and its enantiomer with the (S) configuration can be prepared by appropriate substitution, protection and/or deprotection from the compound of formula II <CHEM> which itself can be prepared by enantiospecific monohydrolysis of 2,2-bis(hydroxymethyl)tetrahydrofuran dibutyrate.

Title: Process and circuit arrangement for controlling biological processes of sewage treating plants
Inventor: MOLNAR LASZLO
IPC: C02F3/00
Filed: 1989-11-10
Abstract: Effluent water is treated by pre-settling, aerobic digestion using air and sludge thickening. Typically, the incoming effluent water is analysed and the carbon dioxide which could be generated by the complete oxidn. of its organic content is determined. The initial oxygen demand of the biological treatment blocks (71....74) is set on the basis of this determination. The dissolved oxygen content of both chambers of the biological treatment blocks (71a....74a), (71c....74c) is measured continuously and oxygen addition is adjusted to suit. - At the end of the treatment process the quantity of the treated water and its oxygen content are measured. The oxygen content is kept within predetermined limits by adjustment of the oxygen addn.. A control system is also proposed, comprising measuring, signal processing and control elements. The measuring elements include:- carbon dioxide sensor (1a) in the main collector channel (1), oxygen sensors (71b...74b) (71d...74d) in both chambers of each biological treatment blocks (71a...74a), (71c...74c), oxygen sensor (9a) and water depth sensor (9b) in the 'Parschall' channel (9). Each measuring instrument is connected to a signal processing unit (101a,171b...174b, 171d...174d, 109a,109b) which feed the process control unit (200). The process control unit (200) controls the control elements (51,56,61...64, 711...746). (1pp Dwg.No.1/2)
Patent JP-S57114270-A (JP)
Title: Semiconductor device
Inventor: TANAHASHI TSUYOSHI
IPC: H01L27/06
Filed: 1981-01-07
Abstract: PURPOSE:To obtain a semiconductor device in which minority carrier is not injected in a substrate and an input protecting effect is large by supplying an input signal to an internal element via a polysilicon resistor crossing with no other wire. CONSTITUTION:An input protection resistor is divided into R1, R1' and R3, R3'. The resistors R1, R1' are formed of diffused layers, and the resistors R3, R3' are formed of polysilicon resistance. When the variation in the potential of a node A with a coupling capacitor C1, the variation VCL of the node C becomes VCL= R1/(R1+R2)XVAL. The variation VCL of the node C is reduced to a value smaller than the built-in potential of the P-N junction by varying the ratio of R1/R2, and the injection of the minority carrier can be prevented. Since the resistor R3 is polysilicon, no injection of the minority carrier is produced to the substrate at the node A. Accordingly, the protecting effect can be obtained without deterioration of the electric characteristics due to the coupling capacitor between the internal elements.

Title: Color liquid crystal panel
Inventor: OHASHI MAKOTO
IPC: G02F1/1347
Filed: 1989-01-10
Abstract: PURPOSE:To eliminate deviation in the threshold value voltage of T-V characteristics of each color and to improve the display quality by making the wavelength dependency of the double refraction value of liquid crystal used for STN type liquid crystal for display different from that of liquid crystal used for an STN type liquid crystal panel for color compensation. CONSTITUTION:The liquid crystal having the wavelength dependency of the double refraction value DELTAn1 is used as the liquid crystal 37 of a driving panel 3 and the liquid crystal having the wavelength dependency of a double refraction value DELTAn2 is used as the liquid crystal 45 of the compensating panel 4. Thus, liquid crystals which differ in double refraction value are used according to wavelength, so a difference delta in retardation is large on a short-wavelength blue side and small on a long-wavelength red side. Consequently, a threshold voltage rises on the blue side of the T-V characteristics and the state that the blue-side threshold voltage is lower than the red-side threshold voltage can be corrected. Consequently, the threshold voltages of red R, green G, and blue B are nearly equalized and the color liquid crystal panel of excellent display quality is obtained.
