Title: Zone selection method in channel changeover during communication
Inventor: FUJIMOTO NAOKI
IPC: H04B7/26
Filed: 1992-02-04
Abstract: PURPOSE:To attain channel changeover with a few frequencies by allowing each zone to use a common zone information notice use frequency to send zone information and allowing a mobile station to monitor the information with a time slot to discriminate a moving destination zone. CONSTITUTION:Two resonance frequencies f1, f2 are allocated to each of zones 2-7, the frequency b2 is used exclusive for notice of zone information and the frequency f1 is used for line control. Own zone information is sent at random by using the frequency f2 of the zones 2-7. On the other hand, the mobile station 1 sets the reception frequency to a frequency f2 only for a time slot not used for communication to receive the zone information from each zone. Then the mobile station 1 discriminates a moving destination zone based on the content of the zone information and a reception level. Thus, the zone selection at 4- channel changeover is quickened and the zone is selected by using a few frequencies.

Title: Driver circuit
Inventor: NAGATOME KENICHI
IPC: G01R31/26
Filed: 1979-02-20
Abstract: PURPOSE: To prevent the driver circuit from overcurrent flowing by making the output of the driver circuit higher in the impedance when the load current flowing to the circuit of a test evaluation device in the semi-conductor integrated circuit exceeds the allowable level.  
     CONSTITUTION: The load current I 0  flowing through the driver circuit 1 is obtained by detecting the differential voltage across the series resistor 2 connected between the driver circuit 1 and the tested semiconductor integrated circuit. The controlling circuit 7 determines whether the load current I 0  exceeds the allowable level IL set by the circuit 6 or not. When I 0 >IL, the output signal of the circuit 7 and the input/output change-over signal is applied to an OR gate 8. This makes the output impedance of the driver circuit 1 higher not only at the output mode of the DUT terminal 4 but also when the load current I 0  exceeding the allowable level IL flows whereby the load current is cut off to protect the driver circuit 1.
