Abstract: PROBLEM TO BE SOLVED: To simplify work for production and to attain reduction in production cost and the reduction in production fluctuation by providing a triplate cable equipped with outer conductors mutually electrically connected proximately to the upper and lower sides of a central conductor. SOLUTION: An outer conductor line 21a for phase deviation correction extending a cable outer conductor 21 and a central conductor 22 are respectively connected and fixed to output signal lines 6 and 6a in electrically conductive states. Signals, supplied from an input signal line 5, are distributed equally to the output signal lines 6 and 6a, while a distribution phase is converted at 180 deg.. At that time, at the position of phase deviation occurrence just for the length of an exposed central conductor 22a connected to the output signal line 6a, the outer conductor line 21a for phase deviation correction is connected to the output line 6, while being controlled into length equivalent to the line 22a of the exposed central conductor 22. Thus, an ideal balun circuit and the equally distributed output signals with the phase difference of 180 deg. can be provided.

Inventor: KOSEKI HITOSHI
IPC: H04L12/70
Filed: 1999-05-06
Abstract: PROBLEM TO BE SOLVED: To quickly recover missing data even on the occurrence of missing of midway data. SOLUTION: An FIFO controller 12 receives audio data via a USB controller 11 and an FIFO 14 sequentially stores the data on the basis of synchronous control by a PLL 13. The data read from the FIFO 14 are given to a P/ S.format conversion section 15, which applies parallel/serial conversion to the data and converts the format of the data into an audio format, a D/A converter 16 receiving the data converts the data into an analog audio output signal and provides an output. The P/S.format conversion section 15 conducts forcible synchronization on the basis of a synchronous flag.  An A/D converter 18 converts an analog audio signal from a microphone 4 or the like into digital data, an S/P.format conversion section 19 applies serial/parallel conversion to the digital data and converts the format of the digital data into a USB format, adds a synchronous flag to the data, which are sequentially stored in an FIFO 20. Thus, synchronization on the occurrence of a missing bit is facilitated.

Filed: 1991-05-30
Abstract: PURPOSE: To provide an integrated circuit and a producing method for the same, with which a mutual connecting structure of high-resistance and low- resistance resistive load elements is formed on a single polycrystalline silicon layer. CONSTITUTION: A mutual connecting region 54 of a polycrystalline silicon layer 32 is masked, a resistant load element region 52 is partially oxidized, and the thickness of the polycrystalline silicon layer in that region is reduced.

Title: Multi-value orthogonal amplitude modulation system
Inventor: KOBAYASHI KENZOU
IPC: H04L27/34
Filed: 1983-07-12
Abstract: PURPOSE:To eliminate the distortions of a transmission waveform by using a device which gives D/A conversion to transmission data via a logical circuit that deletes the DC component and a hybrid circuit which synthesizes the output of a multi-value orthogonal amplitude modulator and a carrier wave. CONSTITUTION:The transmission data undergoes D/A conversion via a DC deleting logical circuit DEL. These converted signals are applied to double-balanced modulators DBM1 and DBM2 via LPF1 and LPF2 respectively. While the output of an intermediate frequency oscillator IFO is supplied to the DBM2 via the DBM1 and a pi/2 phase shifter. Then the outputs of the DBM1 and DBM2 which are subjected to double-balanced modulation are synthesized to the output of the IFO by a hybrid CM to obtain a single output. This operation is performed in the form of the synthesization of addition and therefore no disturbnance is given to a spectrum waveform.

As the paper sheet P is thickened and the stiffness thereof is increased, the quantity of displacement of the folding tendency forming means 32a, 32b in the treating direction is increased. Since a load to be applied to rotary shafts 10, 11 to be generated at the time of pinching the paper sheet P is reduced by retreating the first folding tendency forming means 32a, 32b in response to the thickness of the paper sheet P, rotation of the rotary shafts 10, 11 is not hindered even in the case where the paper sheet to be folded is thick. As a result, the folding operation is smoothly performed, and the paper sheets P are securely folded.
