Abstract: PURPOSE:To prevent occurrence of malfunction due to an error in an information signal by writing the information signal not received to a 1st memory once and transferring the signal to a 2nd memory when no error is detected in the information signal so as to operate the receiver. CONSTITUTION:A signal from a subtractor 32 is once fed to a data latch and error correction circuit 35, where error correction or the like is implemented and when no error is detected, a signal representing it is fed to a control circuit 36 and the content of the circuit 35 is transferred to a memory 37. The information signal received is once written in a 1st memory and when no error is detected from the information signal, the signal is transferred to a 2nd memory to apply the operation of the receiver, then occurrence of malfunction due to information error is prevented.

Abstract: PURPOSE:To prevent interception by sending an identification signal for a data used for scrambling and for plural data so as to decode all of them. CONSTITUTION:The changeover of a switch 11 is controlled by a signal from a switching signal generating circuit 12 and a flag (identification signal) representing the switching state is fed to a multiplexer circuit 6. Scrambling using a key signal K1 is applied to a common information signal string and scrambling by using key signals K1, K2 is implemented to an individual information signal string. Thus, a random signal by key signals K3, K4 at the sender side is switched to apply scrambling and a flag (identification signal) representing the switching is sent together with the key signals K3, K4 or the like. On the other hand, the key signals, K3, K4 are detected at the receiver side and a random signal is generated and the flag representing the switching is detected and the random signals are selected to apply signal descrambling.

Abstract: PURPOSE:To prevent interception resulting from forgery of a reception signal by extracting a data signal for preventing forgery inserted in plural positions in the received signal, comparing them mutually and applying descrambling only when they are coincident. CONSTITUTION:A format of a common information signal string consists of a header ID representing common information, key signals K1, K2 in 16-bit each, key signals K3, K4 in 32-bit each, a 4-bit forgery preventing ID, and a 4-bit channel number or the like, and with a 24-bit error correction code at the end in total 256 bits. The forgery preventing ID provided to a data of the common information signal string and a data of an individual information signal string in a memory 37 is read by a dissidence detection circuit 40 in a timing from a generating circuit 30 and when dissidence is detected, the content of the memory 37 is reset and all channels are brought into the uncontracted state. Thus, the interception is inhibited in an excellent way.

Abstract: PURPOSE:To automatically switch over a trigger operation and a lock operation to each other, by a method wherein a yoke having two magnetic paths is provided with an excitation coil wound on a part thereof common to both the magnetic paths, and a movable core is provided in one of the magnetic paths higher in magnetic reluctance. CONSTITUTION:A unitary body of a magnet 4 having an S pole and an N pole magnetized opposite to each other and a fan-shaped cam 5 is provided in the magnetic path of a part 12 of a double ?-shaped yoke 11 lower in magnetic reluctance than the other part. A sector gear 1 is provided around the magnet 4. A gear 6 driven by a motor is disposed at a position opposite to the gear 1. Moreover, a movable core 32 is provided in the magnetic path of a part 13 of the yoke 11 higher in magnetic reluctance, and a coil 15 is wound on a part 14 of the yoke 11 common to both the magnetic paths. When the coil 15 is applied with a current, the magnet 4 is subjected to a clockwise rotational force, causing the gears 6 and 1 to engage with each other to rotate. When the magnet 4 rotates one-half turn, a head 19 is moved to the operating position and at the same time, the movable core 32 is attracted to the yoke 11, causing the head 19 to be locked.

Abstract: PURPOSE:To improve F/B by providing a phase correcting circuit in a phase-different feeding device for two dipoles. CONSTITUTION:Phase correcting circuit 10, provided at the feeding point of the rear dipole, provides parallel resonance over a low channel (approximately 100MHz) or series resonance over a high channel (approximately 190MHz). Therefore, the attenuation quantity and phase quantity are both nearly ''0'' over low channels of 90-110MHz and phase corrections are made only over high channels. Phase correcting circuit 20, provided at the feeding point of the front dipole, is made to start series resonance at a point of 300 or more MHz and makes phase corrections of about 10 deg.-20 deg..

Abstract: PURPOSE:To make it possible to remove a ghost of a TV receiver easily by only one signal line by making an adjustment of the phase-shifting value of a phase shifter and alternation between antennas by a direct-current control voltage superposed upon a signal path. CONSTITUTION:Signals from antennas 1 and 2 receiving a desired wave at equal- wave surfaces and a disturbing wave differing in propagation path length are passed through switches 3 and 4; one is inputted to variable-phase shifter 6 of a LPF type and the other to fixed-phase shifter 7. Outputs of phase shifters 6 and 7 are mixed by subtraction circuit 5 and then supplied from terminal 12 to a TV receiver via a signal line. Direct-current voltage Vc, superposed upon the signal line, is detected by detection circuit 15 and when it is below the threshold level of transistor Tr17, Tr17 is OFF and emitter voltage Ve of Tr17 is applied across variable capacity element 61 of phase shifter 6. Once voltage Vc exceeds a fixed value, Tr17 turns ON to decrease voltage Ve and when voltage Vc further rises, Tr21 turns ON to alternate switches 3 and 4 by driving relay 22. Consequently, the null point of the composite directivity of antennas 1 and 2 is changed to remove a ghost.
