Abstract: An automatic frequency control tracks a television signal before and after a period of interruption. The automatic frequency control comprises a voltage controlled feedback loop including a voltage controlled local oscillator (18) and a mixer (20) for mixing the output of the oscillator (18) with the TV signal. The output of the mixer (20) is filtered to remove unwanted components of the mixed signal and to equalize sidebands of the television signal. The output of the filter (24) is supplied to a detector (30) which is tuned to a component of the television signal, and produces a voltage corresponding to the frequency of the component. The output of the detector (30) is supplied to the voltage control input of the local oscillator (18) to track the television signal component. Circuitry (71, 72) automatically senses the absence of the TV signal component from the mixer (20), and automatically applies a reference voltage (VR) to the voltage control input of the oscillator (18) when the TV signal component is absent. The detector (30) is operative to detect the television signal component following the application of reference voltage (VR to the oscillator so that when the television signal returns, the detector (30) is capable of tracking it.

Abstract: An injection molding machine employing a mold for molding, e.g., disk-shaped recording medium carriers. A mold-mounting plate (1) has a front surface allowing the mold to be the mounted thereon. A gate-cutting punch (4) is slidably inserted in a hole extending through the plate (1) and opening in the front and rear surfaces of the plate (1). A bore extends longitudinally in the center of the punch (4), and an ejector pin (5) is slidably inserted in the bore. A gate-cutting drive cylinder (6) is mounted on the rear surface of the mold-mounting plate (1), and has a piston (8) capable of abutting against the rear end of the gate-cutting punch (4). The piston(8) is formed with a stepped bore having a large-diameter front portion and a small-diameter rear portion (12) which are aligned on the same axial line. An ejector rod (13) extends through the stepped bore, and has a large-diameter portion (14) slidable within the large-diameter portion of the stepped bore, the front end of the ejector rod (13) being capable of abutting against the rear end of the ejector pin (5). A sprue-ejecting drive cylinder (18) is provided behind the gate-cutting drive cylinder (6) on the same axial line, and has a piston rod (23) connected to the rear end of the ejector rod (13). Thus, the machine includes no hydraulic cylinders incorporated in the mold, thereby eliminating various drawbacks conventionally encountered.

Abstract: Un dispositif de régulation du courant sert à commander la modulation des impulsions en largeur du courant d'un moteur au moyen d'un microprocesseur. Des délais de commande sont inévitables, étant donné que le courant du moteur est reçu par le processeur sous forme de données discrètes. Pour cette raison, il est encore impossible de prévoir la valeur du courant mesuré nécessaire pour assurer la commande de la modulation des impulsions en largeur et pour augmenter de manière satisfaisante le gain de la boucle de régulation du courant. On utilise la structure variable du courant du moteur soumis à une conversion A/N afin d'évaluer le courant du moteur au moment présent, et on ajuste le courant sur cette base. On peut améliorer les caractéristiques de réponse du système de régulation du courant en diminuant de manière équivalente les délais pour que le gain de la boucle de régulation du courant puisse être librement ajusté.

Abstract: The invention relates to a method and apparatus for coding speech signals as digital signals having a low bit frequency. The invention is characterized &squf&  in that the analog signal is converted into a first pulse signal composed of pulses at a mutually equal time interval, the pulse amplitude of said pulses corresponding to that of the analog signal at that instant; &squf&  in that the first pulse signal is converted into a series of p second pulse signals which are each likewise composed of a fixed number of pulses at a mutually equal time spacing which is, however, a multiple of that of the first pulse signal, while the pulse amplitude likewise corresponds to that of the analog signal at that instant, in which connection, of the successive second pulse signals of said series, the position of the first pulse of the respective second pulse signal, viewed in the time domain, is shifted in time with respect to the start thereof over a spacing equal to a multiple n of the said time spacing of the first pulse signal, n successively increasing from 0 to p; &squf&  in that that second pulse signal whose correspondence to the first pulse signal is the greatest is selected from the various second pulse signals and that a first control code for assembling the synthetic signal corresponding to the analog signal is generated in accordance with the time spacing between the start and the first pulse of said selected second pulse signal; &squf&  in that the said first pulse signal is compared with a set of various third pulse signals which are each composed of pulses at a mutually equal time spacing equal to that of the second pulse signals, which pulses have various pulse amplitudes and in which connection, of all said third pulse signals, the position of the first pulse of the respective third pulse signal, viewed in the time domain, is shifted in time with respect to the start thereof over a spacing which is equal to that of the selected second pulse signal; &squf&  in that that third pulse signal whose correspondence to the first pulse signal is the greatest is selected from the said set and that a second control code for assembling the synthetic signal corresponding to the analog signal is generated in accordance with the order number of said selected third pulse signal. Instead of comparing the first pulse signal with the various third pulse signals from the said set (after which said third pulse signal whose correspondence to said first pulse signal is greatest is selected from said set) it is also possible (and preferable) for the (previously) selected second pulse signal to be compared with the various third pulse signals (after which that third pulse signal whose correspondence to said selected second pulse signal is the greatest is selected.

Abstract: A detector for detecting motion in an image represented by a video signal includes delay means (40-52) for concurrently providing lines of signal from five consecutive fields (A-E). Sums (54) of signals (A3,B2) from first and second fields are subtracted (56) from sums (58) of signals (C3,D2) from third and fourth fields to generate first motion indicators (R2,R1). Differences (62) of signals (A3,B3) from the first and second fields are subtracted (64) from differences (66) of signals (C3,D3) from the third and fourth fields to generate second motion indicators (R4,R5). Differences (70) of signals (A3,E3) from the first and fifth fields are generated to form third motion indicators (R7,R6,R5). The first, second and third motion indicators are compared (76) and the largest is provided as a motion signal which is subsequently limited, spread and scaled. Signals used in forming the motion indicators are selected to substantially reject any adverse influence of the chrominance subcarrier. <IMAGE>
