IPC: H04B1/7075
Filed: 1999-12-27
Abstract: PROBLEM TO BE SOLVED: To provide a CDMA demodulation circuit that detects correct inverse spread timing in a short time to start communication. SOLUTION: Inverse spread means 1-3 apply inverse spread processing in different timings to a received signal 101. A power detection means 4 calculates and outputs power values 105-107 of outputs 102-104 of the inverse spread means 1-3. A comparison means 5 compares the power values 105-107 and provides the output of the largest value as a value 108. A phase error estimate means 6 estimates a phase error between a spread code included in a received signal 101 and a spread code 112 generated by the demodulation circuit on the basis of the power values 105-107. A spread code generating means 7 generates a spread code with a phase on the basis of the output 108 of the comparison means 5 at the start of communication, while the means 7 generates a spread code with a phase on the basis of an output 109 of the phase error estimate means in the midst of communication.

Title: Preparation of ketone
Inventor: JIEIMUZU AIAN GUREISON
IPC: C07B61/00
Filed: 1990-12-10
Abstract: The present invention relates to the preparation of aminoalkyl p-hydroxyphenyl ketones. Certain of these ketones are well known as important intermediates in the production of compounds having pharmaceutical activity, for example octopamine or synephrine. The known Houben-Hoesch reaction is a variation of the Friedel-Crafts reaction and involves the condensation of a phenolic substrate with a nitrile in the presence of a Lewis acid catalyst to give a hydroxy-aryl ketone. It is an object of the invention to provide a new or improved process for the manufacture of aminoalkyl p-hydroxyphenyl ketones. According to the invention, there is provided a process for the preparation of an aminoalkyl p-hydroxyphenyl ketone comprising reacting phenol with a nitrile, in the presence of a Lewis acid catalyst, to cause condensation thereof, the process being characterised in that the reaction is carried out in a medium comprising a nitroalkane solvent for the reactants. A preferred but non-limiting feature of the invention is the productiqn of 2'amino-4-hydroxyacetophenones. The present invention is based on the surprising discovery that nitroalkanes are unexpectedly much better solvents for this reaction, being less toxic, giving a better yield and also ensuring a homogeneous reaction medium. The nitroalkanes may also be diluted with a halogenated hydrocarbon solvent, which acts as an inert diluent, thus reducing the amount of nitroalkane used, and making the reaction less hazardous.

Filed: 1990-12-27
Abstract: PURPOSE:To miniaturize it and improve frequency property and enable the control of temperature property by forming a dielectric film on one face of a semiinsulating Si substrate, and arranging a plurality of electrodes on this film, and forming an electrode all or partially over the other surface of the substrate. CONSTITUTION:A dielectric layer (5 in the figure) is made on a semiinsulating Si substrate 8.

By taking the terminals shown by the equivalent circuit in the figure 2 out of these upper and lower electrodes, a capacitor array comprising four capacitors can be obtained. The property of the capacitor basically depends upon the property of the dielectric layer. For example, if the layer is SiO2, the permittivity is 4, but dielectric loss is small, and it has a high Q value, and the permittivity by temperature change is extremely small.
