Filed: 1995-08-22
Abstract: PROBLEM TO BE SOLVED: To provide a demodulator with high accuracy without characteristic deterioration small in size by obtaining a correction use complex coefficient without converting an error of a detection signal into a phase. SOLUTION: An oscillator 1 generates a local oscillation signal. A quadrature detector 2 converts a received carrier band signal into an equivalent low frequency signal based on the local oscillation signal. A complex multiplier 3 applies complex multiplication to the equivalent low frequency signal and the complex coefficient to provide an output of a detection signal. An amplitude error detection section 4 detects a complex amplitude error of the detection signal. A coefficient error calculation section 5 calculates an amount proportional to an error of the complex coefficient from the complex amplitude error and the equivalent low frequency signal and to provide an output of the result. A filter 6 converts an output of the coefficient error detection section into a complex coefficient and gives the result to the complex multiplier 3.  A data recovery section 7 converts the detection signal into the demodulation data and provides an output.

Title: Film coating method
Inventor: MARUYAMA HIROMI
IPC: B05D7/00
Filed: 1985-09-30
Abstract: PURPOSE:To enhance coating workability by enhancing the concn. of the solid in a gel dispersion, by using a low viscosity gel dispersion prepared by gelling a hydrosol of a water-soluble polymer. CONSTITUTION:For example, in preparing a hydrosol by dissolving a hydroxyalkyl derivative of cellulose or hydroxypropyl cellulose in water as a water-soluble polymer, the concn. thereof is adjusted so that the viscosity of a gel dispersion formed by gelling said hydrosol is set to about 1,000cp or less. If the obtained gel dispersion is applied to a solid by a known method, the concn. of the solid in the gel dispersion can be increased and, therefore, a coating time for obtaining a predetermined film thickness is shortened. That is, because the gel of the water-soluble polymer has already destroyed its hydration, the drying speed after the solid has been coated becomes extremely fast and the mutual stickiness of the film is also prevented.
