Title: Transmission system
Inventor: YAMAZAKI SHOICHIRO
IPC: H04L27/34
Filed: 1994-08-26
Abstract: PURPOSE: To turn to a highly accurate timing by using wavelet transformation for the extraction of the timing information of a block cycle from reception signals in multi-carrier transmission based on orthogonal transformation by block processing. CONSTITUTION: On the transmitter side, an inverse discrete Fourier transform unit IDFT 12 generates signals for which M pieces of carriers arranged with equal frequency intervals are synthesized so as to transform the signals on a frequency axis to the signals on a time base. On the reception side, the reception signals are converted to digital signals by an amplifier 16, a filter 17 and an A/D converter 18. Further, the signals are decomposed to the equal frequency intervals by a discrete Fourier transform unit DFT 19 for respective block and the respective signals are respectively demodulated by a demodulator 20 and reproduced to reception information data by a parallel/serial converter 21.  Since the DFT 19 requires timing signals for performing blocking so as to perform the block processing, A/D conversion signals are inputted to a wavelet transform unit 22 and the timing signals are obtained from the output.

Title: Safety valve for nonaqueous electrolyte secondary battery
Inventor: YOSHIDA HIROAKI
IPC: H01M10/39
Filed: 1993-07-22
Abstract: PURPOSE:To improve safety and reliability by pressure-holding an elastic unit for closing a battery case exhaust hole, and further securing holding plates having a through port and a battery case by providing a gas bleeding clearance therebetween so as to prevent bursting by serving as a reversible safety valve of good pressure response. CONSTITUTION:A sheathing can 1 and metal-sealed covers 2 having a battery case exhaust hole are welded and built in with a generating element, and elastic units 3 of EPDM rubber are mounted from above on the exhaust hole of the cover 2 and pressed by holding plates 4 having an opening part in the center. Next by resistance- welding the covers 2 and protrusion parts 5 of the holding plates 4, a gas bleeding clearance is formed by the protrusion parts 5 between the covers 2 and the holding plates 4, to constitute a safety valve. This safety valve is operated as a reversible valve at low pressure time of about 3 to 15kg/cm<2>, and when a battery internal pressure rises, the elastic unit 3 is lifted to discharge gas from the gas bleeding clearance. When the battery internal pressure exceeds 15kg/cm<2>, the elastic unit 3 is discharged from the opening part of the holding plate 4, to efficiently discharge the gas. Thus by preventing bursting, safety, reliability and leak resistance are improved.

Title: Convergence correction device
Inventor: ABE FUMIO
IPC: H04N9/28
Filed: 1989-08-04
Abstract: PURPOSE:To easily correct the deviation in the convergence caused due to a change in a horizontal deflection frequency by connecting a capacitor in parallel with one terminal of a differential coil and using the capacitor to control a deflection current flowing to a horizontal deflection coil. CONSTITUTION:When a horizontal deflection frequency fH is changed from 15.75Hz into 311.5kHz, a horizontal deflection magnetic field 13 is going to deviate upward. Moreover, when the horizontal deflection frequency fH is changed from 31.5Hz into 64kHz, the horizontal deflection magnetic field 13 is going to deviate upward again. In this case, a capacitor 20 connecting in parallel with a differential coil 17 acts effectively and a current flowing to an upper horizontal deflection coil 11 is increased more relatively than the current flowing to a lower horizontal deflection coil 11b. Since the magnetic lines of force in the horizontal deflection magnetic field 13 is prevented from being interrupted at the tip of an electron gun 7, the distribution state of the horizontal deflection magnetic field 13 is made proper.
