摘要： The present invention discloses a receiver and a receiving method for spread spectrum communication for use in the digital communication system. The receiver basically comprises a receiving circuit, a spread signal distributing circuit, a pseudo noise signal generating circuit, an activating circuit, correlation detecting circuits, an initial seizing control circuit, a synchronization sustaining control circuit, a synchronization control circuit and a demodulating circuit. If a phase lock condition is broken within a short period of time, such condition is sustained until phase lock is recovered so that communication can be started again immediately after phase lock is recovered without initialization for each asynchronization. The receiving circuit is very much simplified and particularly, the Costas Loop demodulating circuit detects the phase lock condition when the signal obtained by multiplying the signal of which phase is shifted by 90.degree. and the reversely spread signal is within the preset range without using a phase shifter or other multiplying circuit. Accordingly the circuit structure of the receiver as a whole can be simplified.

摘要： A safety device to prevent a vehicle-loaded electronic equipment from malfunctioning due to an influence of the high-level electric field. An antenna pattern for detecting the electric field is formed on the same printed board as the electronic equipment, and an electric signal level of the output from the antenna pattern is determined. When the determined level reaches a level at which the electronic equipment may malfunction, the equipment is forcibly controlled toward a safety range of operation.

摘要： A length of time required for the verification of data transmitted from a satellite or satellites is reduced. A distance r1 calculated from a time delay required for the propagation of a radio wave between a transmitting and a receiving site is obtained, as is a line-of-sight distance r2 which is calculated from the positions of a satellite and a point of reception. When a difference between these two distances is small, data from these satellites are regarded as valid data. However, when the difference is large, data is regarded as involving a large error. The position of the point of reception is determined by a positioning calculation which utilizes data from predetermined three or four verified satellites, or is entered by an operator. The position of the satellite is obtained from orbital data which is delivered by that satellite.
