Inventor: MARUOKA MASATO
IPC: G01S1/68
Filed: 1994-09-12
Abstract: PURPOSE: To obtain a phase detection device which enhances the detection accuracy directly under a beacon. CONSTITUTION: A sample-timing generation part 51 which generates a sample clock signal used to sample an AM-demodulated signal in synchronization with an FM-demodulated signal is installed at a beacon receiver which receives a signal which is AM-modulated by road information and whose phase has been AM-modulated to an in-phase and an antiphase on the basis of information on a running direction in synchronization with a signal to be modulated. An up-down-pulse generation circuit 52 generates up pulses and down pulses according to the level of the taken-into AM-demodulated signal on the basis of the sample clock signal. An up-down counter 54 increases a counted value by the up pulses, and it decreases a counted value by the down pulses. A changeover part 53 for squelch makes the counted value valid only when a reception level is larger than a definite threshold value.  A phase judgment circuit 55 judges the in-phase and the antiphase when the counted value exceeds a definite judgment threshold value within an arbitary time inside one data frame.

Filed: 1988-09-02
Abstract: PURPOSE:To shorten a time required for a search processing by setting the number of records managed directly by a master record or a managing record less than a prescribed value by distributing the management of a slave record in laminated manner by the managing record when the number of slave records which belong to the master record is increased. CONSTITUTION:The slave record from which a registration request is issued newly is stored in a null block by a record registration means 2, and a record connection means 3 traces managing information in the laminated manner from the master record to which a stored slave record belongs and searches a position to insert the slave record, and also, performs the connection of the slave record by changing the managing information. When the number of record which belongs to the managing record managing the slave record directly exceeds the prescribed value due to the connection of a new slave record, a managing record generating means 4 generates the managing record, which takes partial charge of the management of the record. In such a manner, it is possible to perform a processing to find out the inserting position of the new slave record even when the number of slave records exceeds that of the master records.
