Filed: 1980-01-19
Abstract: PURPOSE:To prevent error operation caused by external noise by using the differential waveform of a flyback pulse as a comparison signal of a phase discriminator. CONSTITUTION:Flyback pulse a''' is applied to the differential circuit consisting of capacitor C9 and resistance R8 and the differentiated pulse is applied to the base of transistor TR5 which is one transistor of the differential amplifier. Thus, TR4 and TR5 are conducted in the first half period and the latter half period of pulse a''' respectively. In other cases, TR4 and TR5 are not conducted even if any signal is entered into the emitters of amplifiers TR4 and TR5. Therefore, even if an abnormal signal is received, charging current d'' at point (f) is equal to discharging current e''' and no discrimination signal is generated at point (f). Thus, horizontal oscillation frequency is not lowered abnormally and the anode voltage of cathode- ray tube is not abnormally raised.

SOLUTION: This zoom lens is constituted of the first group Gr1 that consists of the first lens L1 of a concave negative meniscus shape(both surfaces are aspherical surfaces), the second lens L2 of both convex shapes and a diaphragm A in order from the side of an object and on the side of the object and the second group Gr2 that consists of the third lens L3 of a convex positive meniscus shape (both surfaces are the aspherical surfaces and the diffraction optical surface on an object side) on an image side and the fourth lens L4 of the concave negative meniscus shape on the object side. Then, it is moved so as to make an interval between the first group Gr1 and the second group Gr2 narrow in zooming from the wide angle end to the telephoto end.  Thus, when the diffraction optical surface is used, the color aberration that is hardly corrected in the case of constituting it of only a refracting optical surface is excellently corrected.

Abstract: PURPOSE:To attain stable velocity feedback without being affected with a cable impedance of a speaker by providing a bridge circuit in a speaker system and connecting the circuitry from the bridge circuit to a control amplifier with a signal cable. CONSTITUTION:Impedance elements 5, 6, 7 are given to a speaker system 12' in the speaker device. The balancing condition that no voltage by a drive voltage source 22 is produced between points X and Y of the bridge circuit section is given in the following Equation and the effect of a cable impedanace of the speaker is not given; Z'8.Z6=Z5.Z7, where Z'8 is the impedance of an element 8', Z5, Z6, Z7 are impedances of elements 5, 6, 7. Although an impedance element 24' of the output cable of the bridge circuit is inserted at a part up to the input of a differential amplifier 9, since the signal change due to the impedance is caused in-phase, the signal change is eliminated by a differential amplifier 9. Since the effect of the cable impedance is eliminated from the balancing condition of the bridge circuit in this way, the distortion reduction effect by velocity feedback is activated stably.

Abstract: PURPOSE:To prevent transmission from being held up by discriminating whether an F bit should be added to the last frame or not at the time of transmitting a series of frames reported from a transmission processing part and stopping addition of the F bit at the time of indicating the continuous transmission request. CONSTITUTION:A reception processing part 2 checks frames, When report of frames is confirmed, transmission data exists and transmission of all frames is not completed, a continuous transmission control flag is set. A P bit is checked in other cases, and the P bit is checked also after the continuous trans mission control flag is set in this case: and when the P bit is set, a transmission processing part 3 is started. This processing part 3 generates a transmission table based on transmission data when transmission is requested by a higherorder program part 5. When the number of outstanding frames is not its maximum, it is checked whether transmission data is left or not; and when it is not left, the continuous transmission control flag 4 is turned off and a transmission request is generated to cause an interrupt.
