Title: Data transmission/reception system
Inventor: TAKADA TAKEHIKO
IPC: H04B14/00
Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To allow a data reception terminal to correctly decode a digital audio signal and a digital video signal included in a modulation signal in the case that a modulation signal resulting from coding, multiplexing and modulating a program that requires a transmission rate in excess of a maximum transmission rate of a communication channel is outputted from a server. SOLUTION: In the case that a modulation signal resulting from coding, multiplexing and modulating a program that requires a transmission rate in excess of a maximum transmission rate of a communication channel 102 is outputted from a sever 101, a data reception terminal 103 receives the modulation signal at a transmission rate below the maximum transmission rate of the communication channel 102, a demodulation means 104 demodulates the received signal to obtain a multiplexed stream. Then the multiplexed stream is stored tentatively to a data storage means 106 via a switch 105 and a multiplexer/demultiplexer means 107 conducts demultiplexing of the stream and a decoding means 108 conducts decoding of the stream.

Abstract: PURPOSE:To make measurement of a high resolution, even where the clock frequency of a pseudo-random signal is restricted, by equipping a measuring device concerned with a signal waveform forming means to generate trinary pseudo-random signal which takes a third value between the two values of a binary pseudo-random signal in synchronization therewith. CONSTITUTION:M-series signals are used as pseudo-random signal, and a pseudo- random signal generation part 3 consists of a feedback loop including exclusive logical sum and a shift register by ECL element. This pseudo-random signal generation part 3 generates 3a signal one after another in synchronization with binary pseudo-random symbol signals generated being driven by clock signals fed externally. The generated signal is composed of pulses of +V or -V having a certain width corresponding to each symbol signal and a signal division which takes a third value between + or -V. As a result, a trinary pseudo-random signal 4a is obtained, as the output signal from the generation part 3, which consists of a row of pulses of +V or -V partitioned by the signal division to take the third value.

Abstract: PURPOSE:To obtain ion source whose ion beam intensity is great by constituting the photoionized ion source used for a heavy ion accelerator out of a supply source of electron molecules, an electrode for forming electrostatic inductive resonant conditions in molecules, and an exciting light source for exciting molecules in resonant conditions. CONSTITUTION:Potassium atoms are ejected from an atom molecule supply source 3 into a vacuum vessel not shown in the figure, and are let pass between a low poten tial electrode 1 for parallel electronstatic field to which proper voltage is applied and a high potential electrode for electrostatic field application. Moreover, the beams from an exciting light source 4, that is, the second higher harmonics, which are generat ed by condensing the fundamentals of the pigment laser for nitrogen laser excitation in DKP crystals, are introduced between the electrodes 1 and 2 so as to produce photoi onization. Next, the produced ions are accelerated immediately in the direction of the electric field, and those are added in an electrostatic lens system 5 and are made into beams. Hereupon, a metallic mesh is spread beforehand in the small hole 6 of the electrode through which ions pass, so as to make the electric field of an ionization area uniform as far as possible. Thus, the low ionization efficiency having a normal photoionizing source to do photoionization in zero magnetic field can be improved sharply.

Filed: 1986-05-15
Abstract: PURPOSE:To keep the optimum contact of a tape and head, and minimize the fluctuation of reproducing output by controlling the tension giving to a recording medium according to the reproducing output transmitted from the recording medium. CONSTITUTION:The reproducing output transmitted from a recording medium 1 is detected by detecting means 2-4.
