IPC: H04L27/14
Filed: 1979-03-16
Abstract: PURPOSE:To omit the frequency control by delivering the control signals according to intervals of the synchronous pulses synchronized with the modulation signals and then delivering the demodulation signals via the control signals. CONSTITUTION:With push of a certain key, transmission signal RS and signal SD received the pulse modulation based on the key input are transmitted through control circuit 1. Signal SD varies the division ratio of divider 3. The output of divider 3 is supplied to terminal CK of FF4 to deliver the rectangular waveform groups of different cycles according to signal SD. The output of FF4 is converted into the sine wave through waveform shaping circuit 5 via AND gate 13 to obtain FSK modulation signal FS which is then delivered through speaker SP. At the same time, this output signal FS is transmitted to be supplied to mike MIC. Waveform shaping circuit 9 generates pulse signal AP which is synchronized with signal FS. Reception signal generating circuit 11 influences divider 3 to give division to the frequency of circuit 2. On the other hand, output pulse SP of synchronous pulse generating circuit 10 resets divider 3 and FF4 to be then supplied to terminal CK of FF12. Then demodulation signal RD is obtained through FF12.

Abstract: PURPOSE:To obtain a substrate sucking structure capable of corresponding to a plurality of pieces of substrates different in size by one piece of a substrate holding plate by a method wherein suction holes to interconnect to sucking holes other than sucking holes to correspond to a substrate are turned into a shut state by opening and shutting means. CONSTITUTION:In the case of a substrate 8 of a size shown by two dotted chain lines, plugs 71-74 are loosened to turn suction holes 61a-61d into an opened state and plugs 75 and 76 are turned off to turn suction holes 61e and 61f into a shut state and a substrate sucking structure is used. Accordingly, as the holes 61a-61d only are interconnected to a suction groove 21 through interconnecting holes 62a-62d, the groove 21 is evacuated to a vacuum state by a vacuum generator through a piping 5 and a suction hole 22. Whereupon, the holes 61a-61d only are evacuated to a vacuum state. That is, sucking holes 63a-63d only to correspond to the substrate 8 result in being evacuated to a vacuum state. In such a way, in case the width of the substrate 8 is the same and its length only is changed, the substrate sucking structure can cope with a plurality of pieces of substrates different in size by just opening and shutting the plug 7 (71-76).

Abstract: PURPOSE:To perform one-side plating by flowing upwards molten metal by an electromagnetic  repulsion in order to contact the rising portion of bath with the one side of steel plate by providing a low frequency induction device at the side and bottom portions of bath by turning the  fireproof block side upwards. CONSTITUTION:The low frequency induction device 11 consists of the iron core 12, the primary  coil 13 surrounding the iron core, and the fireproof block 15 with the U-shaped secondary  groove 14 on the outside of the coil. When the fireproof block 15 is attached to the side and bottom portions of bath by turning its side 16 upwards, an electromagnetic repulsion is induced radially in ralation to the primary coil 13 in the molten metal and thereby the surface of bath is  risen to contact it with the lower side of the steel plate being transported. The flow of the  molten metal is expelled aslant upwards or sidewards at both ends of the steel plate 1 and thus  the inflow of it to the upper surface of steel plate is avoided. And, when the rising portion of  the bath surface comes into contact with the lower surface of steel plate 1, the rising of the bath  surface is continued until the steel plate is turned by the roll 8 due to the wettability of the steel  plate 1 and the speed of the steel plate 1. Thus, good one side plating can be performed.
