Filed: 1997-05-20
Abstract: PROBLEM TO BE SOLVED: To enlarge the covering range of one radio base station by providing a movable optical transmission/reception part provided with a condensing lens in the radio base station of a radio communication system. SOLUTION: When a call is terminated, the radio base station 1-2 sends an incoming call to a radio terminal 1-1 and simultaneously issues a scanning instruction to the optical reception parts 1-20a, 1-20b,...1-20n. The radio terminal 1-1 originates a link channel establishing request from an optical emission part 1-10 and the respective optical reception parts 1-20 move the direction of an optical communication module and scan the inside of an area. When the optical reception part 1-20a ends scanning in a best reception direction and the link establishing request is transferred to the radio base station 1-2, the other reception parts stop scanning and prepare for the link channel establishing request from the other radio terminals at the point of time.  In such a manner, by utilizing the high sensitivity sensor of sharp sensitivity characteristics for the optical reception part of the radio base station, a communicable range is enlarged, photosensors are reduced and simple constitution is attained.

Title: Vertical synchronizing signal separation circuit
Inventor: IWAI MASAYUKI
IPC: H04N5/10
Filed: 1986-06-20
Abstract: PURPOSE:To separate and extract digitally a vertical synchronizing signal and to easily attain IC formation by preparing two kinds of clocks, and when either one of them is continued N times, determing an input level and setting up N properly to separate and extract the vertical synchronizing signal. CONSTITUTION:In a vertical synchronizing period, clocks are outputted frlm an AND circuit 13 and no clock is outputted from an AND circuit 15. When a counter 17 counts up its contents and outputs '8', the output of a decoder 18 is turned to the H level and the output of clocks to the counter 17 is inhibitted by a clock inhibiting gate circuit 16. An AND signal between the H output of the decoder 18 and the AND output of the circuit 13 resets a counter 21. After the end of the vertical period, the counter 21 counts up its contents every 8 clocks, the output of a decoder 22 is turned to H and the output of the decoder 18 is turned to L. In an equalizing pulse period within the vertical synchronizing period, clocks are inputted to the counter 21, but the inputted clocks are not reached to '8' and the output of the decoder 18 kept at H as it is. Thus, the output H period of the decoder 18 coincides with the verticalp period and can be separated.
