Title: Sigmadelta modulation type analog/digital converter
Inventor: IMAMURA MAKOTO
IPC: H03M3/04
Filed: 1989-03-23
Abstract: PURPOSE:To attain highly accurate digital conversion by allowing an arithmetic section to calculate and output a deviation between an analog input and 1st and 2nd D/A converter section and operating the 1st and 2nd D/A converter sections switchingly. CONSTITUTION:The 1st and 2nd D/A conversion sections 12, 13 convert its input into an analog value synchronously with a clock CLK and output the result to an arithmetic section 1. The arithmetic section 1 calculates and outputs the deviation between an analog input Ain and the sum of outputs of the 1st and 2nd D/A conversion sections 12, 13. That is, the 1st and 2nd D/A conversion section 12, 13 are used and the 1st and 2nd D/A conversion sections 12, 13 are used switchingly so that the high level of the output of the 1st and 2nd D/A conversion sections 12, 13 does not last over one clock period. Then since the number of the fall per the time of the output of the 1st and 2nd D/A conversion sections 12, 13 is made constant, the error is easily corrected.

Title: Overvoltage protection circuit of isdn feeder circuit
Inventor: TAKATO KENJI
IPC: H02H9/04
Filed: 1990-03-20
Abstract: PURPOSE:To protect a feeder circuit from an overvoltage such as lightning surge by clamping an excessive negative surge through a varistor by means of the output diode of the feeder circuit. CONSTITUTION:When an excessive negative voltage is applied, a forward bias is given between the base and collector of a transistor TR3 and reverse voltages are respectively applied between the base and emitter of transistor TR3 and TR1. In this case, when an excessive negative surge is clamped by a varistor VR2 through the output diode DB of a feeder circuit 24, the application of an overvoltage to a feeder circuit 24 output can be prevented by the withstand voltage of the diode DB. Thus, it is possible to protect the feeder circuit 24 from an overvoltage such as lightning surge and to prevent the characteristic deterioration and worst destruction of the transistors TR1 and TR3. Further, it is also possible to prevent the influence on a DC supply voltage itself.

The film is formed while the light from a mercury lamp 6 of 1kw output and 2537Angstrom  wavelength is projected on the film at this time. The supplied gaseous O2 is thereby activated and the thin film having 52K superconduction transition temp. Tc is obtd. In this case, the thin film does not exhibit the superconduction transition unless the light of the mercury lamp 6 is projected on the film. The thin film having 73K temp. Tc when the substrate temp. is 710 deg.C is thus obtd.

Title: Digital data conversion method and device therefor
Inventor: NOGUCHI TADASHI
IPC: G10L19/00
Filed: 1995-03-29
Abstract: PURPOSE: To reduce the quantization noises caused in a compression coding process down to a level where no hearing problem is produced. CONSTITUTION: In a compression coding process that is performed before a recording or sending process, the output digital data pour that undergone the polygonal line compression are decoded by a decoder DC into the decoded digital data DDC of the same number of bits as the input digital data DIN. The data DCD are subtracted from the superposed digital data D+ which undergoes no polygonal line compression yet, and the error data DE are outputted. Then the audible area component error data DH are extracted out of the data DE by a digital filter FT and added to the data DIN. Thus the data DH are fed back and turned into the the data D+ . The polygonal line compression is given to the data DIN after the data DH are excluded out of the data DIN. Then the data DIN are recorded or transmitted. As a result, the quantization noises can be reduced in an audible area after the decoding is carried out in a reproduction or reception mode.
