摘要： Magnetic recording and reproducing apparatus includes a delay circuit (13) with a plurality of output terminals (13A to 13C), one output terminal (13B) providing an output video signal delayed by a deviation of the horizontal synchronization alignment between adjoining record tracks, and another output terminal (13C) providing another output video signal delayed by one horizontal synchronization interval (1H). Signal selection switch circuitry (6,14) sequentially selects the reproduced video signal to be sent to the delay circuit (13) and also selects the delayed reproduced video signal during an interval for which an auxiliary head (3) is selected in place of a main record and/or playback head (2) in a variable speed reproduction mode, so that a reproduced video signal with continuous horizontal synchronization alignment can be secured and video images with good picture quality can be achieved.

摘要： PURPOSE:To prevent the erroneous elimination of a tape pattern by providing an amplifier to execute slowly the switching of a bias and interrupt an input at the time of the switching. CONSTITUTION:Bias generating amplifiers 7a (for A channel) and 7b (for B channel) generate a bias voltage at the time of recording in which both rise and fall are gradually changed from an approximately rectangular wave timing signal outputted from a timing generator 6. As one example of the circuit, an integration circuit with a limit to use an operational amplifier is used. The inclination of the change of rise and fall is set to the extent or below in which the unnecessary current induced to heads 102a and 102b with it does not eliminate a tape pattern erroneously, and timing is controlled by the generator 6 so that the stable period of the bias voltage covers the period necessary to the recording. Thus, the erroneous elimination of the pattern can be prevented.

摘要： PURPOSE:To eliminate the need for a short ring and to reduce the size of constitution by fitting two couples of magnetic heads in specific relation, and specifying the channel arrangement of a rotary transformer and short-circuiting channels selectively. CONSTITUTION:The two couples of heads 2a and 2b, and 3a and 3b which are different in track width and also different in azimuth angle between opposite heads are fitted to a rotary drum 1 which is wound with a magnetic tape 4 by >=180 deg. so that the head 2, etc., in one couple which has one azimuth angle and the head 3, etc., in the other couple which has a similar azimuth angle are not close to each other. Further, the channels of the rotary transformer consisting of couples of transmission coils 12a and 16a-13a and 17a corresponding to the respective heads are also arranged similarly and the unused channel formed of the couple of coils 12a and 16a is short-circuited by a transistor which turns on in response to a signal. Consequently, crosstalk is precluded without using any short ring to reduce the size of constitution and speed up the operation.

摘要： PURPOSE:To reduce the short ring of a rotary transformer, to miniaturize the titled device and to upgrade its performance by short-circuiting, at necessities, a channel of a flying erase head and a channel of an adjacent recording/ reproducing head. CONSTITUTION:The flying erase head 4b for erasing inverse directional recording is mounted in such a position that it is apart from other magnetic heads 2a, 2b, 4a at least more than an angular interval corresponding to a PCM area and that the channel covered by this head 4b comes between a channel of the recording/reproducing magnetic head 4a and a channel of a flying erase head 4 for forward directional recording/erasing at the time of rotary transformer. On the other hand, in the case of erasing with the head 4b, since the head 2a does not operate, if a control signal supplied to the terminal 21 of a short- circuiting circuit connected to the coil 18a for a video channel converted by the head 2a neighboring the head 4b converts to a level H, a transistor 20 turns on, and the transmission line.

摘要： PURPOSE:To increase relatively the level sensitivity and to apply easily the non-linear peaking for the input signal of the low level by giving the same phase signal to one edge of the diode switch having the level inductivity and giving the reverse phase signal peaking signal to other edge. CONSTITUTION:A transistor amplifier 14 derivates the same phase and reverse phase output signals corresponding to the input signal, an inverting peaking amplifier 15 applied the peaking in the prescribed frequency of the input signal, and derivates the reverse phase output. The above-mentioned reverse phase output of the amplifier 15 is given through switches D1 and D2 to the same phase output edge of the above-mentioned amplifier 15. The switched D1 and D2 are turned on by the prescribed signal level. In such a way, to both edges of the switches D1 and D2, the same phase signal and the reverse phase signal are respectively applied, and therefore, the 'ON' sensitivity goes to be high by the reversal polarity, and the non-linear operation is easily executed even for the input signal of the low level.

摘要： PURPOSE:To facilitate an input operation, by arraying plural thin transparent electrode elements in parallel to each other and so that they are orthogonal to each other at the upper and lower sides of a transparent and insulated plate, putting these electrode elements on a display and detecting the pressed position by a change of the capacity. CONSTITUTION:Plural thin transparent electrodes Y1-Y5 are arrayed in parallel to each other on a display 1, and an electrode sheet 3 containing the parallel thin transparent electrodes X1-X5 in the direction rectangular to Yn is stacked on the electrodes Y1-Y5 via a transparent and insulated plate 2. The electrodes Y1-Y5 and X1-X5 are connected to both terminals of a capacitor 6C of an oscillator 6 via the switches A-E are a-e, respectively. These switches are controlled 15 with the signals P and Q, and the ON of a switch has a round while another switch is kept on. The capacity varies with a push of a point S, and then the oscillating frequency varies to be supplied to a converting circuit 10 after an F/V conversion. At the same time, the X and Y coordinates are obtained at the point S with the signal R corresponding to the signals P and Q supplied from a control circuit 15. Thus the assured input information is applied by pressing a desired point on the display 1.

摘要： PURPOSE:To easily form an electrode body consisting of alternately insulated linear electrodes so that the pulling state of each linear electrode can be uniformalized by using a difference in the thermal expansion coefficient between each linear electrode and insulated supporting body. CONSTITUTION:The metal plate 20 with a fixed thickness consisting of the same materials is bonded to the joint 15 of the metallic frame structure 12 by means of welding and the thickness of the section is increased and reinforced. Then the metallic frame structure 12 is loaded on the ceramic substance 13 through the glass paste 14 and is fixed in the burning furnace. When the metallic frame structure 12 is entered in the burning furnace with an increased thickness of the joint 15, uniform force is applied to the whole bonding section of the metallic frame structure 12. As a result, the whole is uniformly thermally expanded and each linear electrode 11 is fixed with uniform tension.
