Inventor: YOSHIDA MITSUHARU
IPC: G02B21/00
Filed: 1989-10-13
Abstract: PURPOSE:To simplify the constitution and realize low-cost formation by moving a 2nd slit plate, which has one slit crossing at one place to the slit of a 1st slit plate having one snaking slit passing part of a light beam, relatively to the 1st slit plate. CONSTITUTION:The 1st slit plate 15 has the snaking slit 15a where V-shaped parts connect with one another as shown by an arrow Y. The 2nd slit plate 16, on the other hand, has one linear slit 16a extending almost at right angles to the direction of the arrow Y. Those slits 15a and 16a cross each other only at one position while the slit plates 15 and 16 are put one over the other. Therefore, illumination light 11 is projected only from the intersection of the slits 15a and 16a. Consequently, the light beam makes a two-dimensional scan only by the movement of the two slit plates. Further, a function which stopping down the light beam is obtained. Consequently, the constitution is simple and the low-cost formation is possible.

Filed: 1989-10-16
Abstract: PURPOSE:To enhance a false target suppressing function still more by utilizing the position data of a false target obtained by a central processing unit and prohibiting the passage of a false video by a prohibiting gate generator and a gate circuit. CONSTITUTION:A prohibiting gate generator 1 generates a prohibiting gate to the position of a false target from the false data (the azimuth and distance data of the false target) sent from a central processing unit 3, the azimuth signal showing the azimuth of an antenna 4 sent from the antenna 4 and the trigger signal showing the standard of a distance sent from a transmitting part 5. The prohibiting gate is sent to a gate circuit 2 and the passage of the video signal outputted from a passive decoder 6 is prohibited for the period of the prohibiting gate. As a result, the azimuth of the video displayed on a scope advances and, therefore, the azimuth signal to an indication apparatus is delayed by an azimuth delay circuit 8 to correct azimuth shift.

Title: Radio packet channel switching method
Inventor: ICHIKAWA TAKEO
IPC: H04J3/16
Filed: 1995-10-17
Abstract: PROBLEM TO BE SOLVED: To minimize the momentary break of communication due to the occurrence of channel switching during satisfactory communication and to prevent the traffic increase of a control signal and the increase of control delay which are accompanied with frequent occurrence of channel switching. SOLUTION: When detecting the interference (Sc1), a radio terminal 1-2 transmits a channel switching request signal CCH to a base station 1-1; and if channel switching is not performed over a certain time after transmission and the interference continues, the terminal 1-2 transmits the channel switching request signal CCH again. The frequency in retransmission is given when the signal is retransmitted, and transmission of the channel switching request signal CCH is terminated when the interference is resolved. When receiving the channel switching request signal CCH, the base station 1-1 performs channel switching (Sc9 and Sc9') if there are no other connected radio terminals or there are other connected radio terminals and the frequency in transmission of the channel switching request signal CCH exceeds a threshold B.
