Filed: 1984-10-23
Abstract: PURPOSE:To eliminate the need for the separate provision of a shutter function, and to improve reliability by forming a second gate discharging charges generated by photoelectric conversion to a photoelectric conversion section for a TV camera apart from a transfer gate.

Title: Radio communication controller
Inventor: SAKURAI KATSUYOSHI
IPC: H01Q1/00
Filed: 1994-08-25
Abstract: PURPOSE: To prevent deterioration in a data transmission efficiency due to a sporadical obstacle. CONSTITUTION: Data are received by plural directional antennas 1-6 installed in each direction and receivers 11-16 connected to them and the data are given to a statistic control section 17. The statistic control section 17 generates a table in which the antennas 1-6 are numbered in the order of higher reception radio wave strength. Then a frequency of occurrence of errors in a communication route through each antenna is managed. When the frequency of occurrence of errors exceeds a prescribed value, the route is not used for data reception. That is, the data are received with a route whose reception radio wave strength is highest among the routes in which the frequency of occurrence of errors is a prescribed value or below. The statistic control section 17 instructs a changeover logic section 18 to select the route as above.  As a result, the number of occurrence of errors is reduced and retrial processing is decreased.
