IPC: H04L27/18
Filed: 1988-06-30
Abstract: PURPOSE:To make an input signal to a power amplifier as a signal with nearly constant amplitude and to increase a power per one wave without large sized power amplifier by synthesizing each output of n-set of modulators in a way that the maximum amplitude is not overlapped. CONSTITUTION:n-Set of base band signals being modulation signals are inputted to corresponding modulators 3, 5 while each data change point is deviated by 1/n each of a clock period of a clock signal with each other. Then each output of the n-set of modulators is synthesized so that each maximum value is not overlapped with each other, resulting that the input signal to a power amplifier 9 is a signal with a nearly constant amplitude. Thus, it is possible to increase the average level of an input signal to the power amplifier 9 just before the saturation level of the power amplifier a and the power per one wave is increased without increasing the size of the power amplifier 9.

Filed: 1998-06-11
Abstract: PROBLEM TO BE SOLVED: To upgrade an external appearance by inserting a cylindrical canvas in which an insertion bar is inserted into a periphery of a mold with a groove so as to dispose the bar in the groove of the mold, fixedly mounting it, and then pressurizing it to manufacture a preform of the state that the canvas is forced together with the bar into the groove, thereby eliminating exudation of rubber from a joint part. SOLUTION: A mold 11 in which a jacked is engaged is introduced into a vulcanizing pan, heated, and pressurized. Then, a cylindrical canvas 1 is forced together with an insertion bar 10 into a groove 11 of the mold to manufacture a preform. Before the canvas in which the bar 10 is inserted is heated and pressurized, the bar 10 is projected from a surface of the mold 10, but after it is heated and pressurized, the projected bar 10 is pressurized by a pressing plate, and the canvas 1 is forced into the groove 12 of the mold. Thus, even if unvulcanized rubber flows into the groove in the next vulcanizing step, a joint part is not largely deformed. Thus, puncture fault for overflowing the rubber from the part scarcely occurs.
