Title: Encoder and decoder
Inventor: SHIMIZU TETSUYA
IPC: H04N9/888
Filed: 1990-10-17
Abstract: PURPOSE:To enhance the burst error correction performance without increasing the hardware quantity so much by extracting one constituting unit of two error correcting codes constituting a product code at every code group and transmitting the data in unit of code group. CONSTITUTION:In an external coding circuit 140, information data inputted from a special reuse interleave circuit 101 is inputted in parallel to a delay circuit 102, P0 parity calculating circuit 110, P1 parity calculating circuit 120, and P2 parity calculating circuit 130. Parity calculating circuits 110, 120, and 130 all have a similar circuit configuration, except that each coefficient of the generating matrix in a generating matrix coefficient table 112 is different from another. These 3 circuits calculate 3-word parity inspection words in parallel. Thus, the maximum burst error length that can be corrected by another code is increased plural times, whereas a reqired hardware quantity of the encoder/decoder is not increased so much. Further, as for information data, it is not necessary to change the arrangement of information data, and as long as information data is arranged in a desired order before error correction signalizing, nothing affects the data arrangement.

Filed: 1987-11-04
Abstract: PURPOSE:To reduce a band required for call processing signal transmission on a PCM transmission line by providing 1st and 2nd serial data interface circuits detecting a flag and a bit error of a layer 2 in a call processing signal and a multiplex circuit so as to multiplex an ISDN call processing signal on a subscriber line. CONSTITUTION:Line termination circuits LT 1-m, 1-n extract a call processing signal on digital subscriber lines 2-m, 2-n and send the result to serial data interface circuits SDI 3-m, 3-n. The call processing signal from the SDI 3-m, 3-n is sent respectively to the lines 2-m, 2-n. A multiplex circuit MUX 4 adds a digital subscriber line number and a channel control signal to a call processing message received from the SDI 3-m, 3-n and sends the result to the SDI 5. As a result, a call processing message on the digital subscriber line different from each other is multiplexed to the same time slot on the primary group PCM transmission line 7. Thus, the call processing signal transmission band on the primary-order group or high-order group PCM transmission line is reduced.

Title: Optical signal sending system
Inventor: FUKUOKA TAKASHI
IPC: H04B10/556
Filed: 1987-11-09
Abstract: PURPOSE:To prevent the increase in a pulse width distortion for a signal having the fluctuation of a mark ratio by sending an optical signal while an average optical power in a silence condition is approximately equal to the average optical power in a signal condition in which the optical signal exists. CONSTITUTION:A light transmitter 2, in a silence condition E1, outputs the bias light of a certain constant level L1 and in a signal condition E2, takes out the optical signal obtained by quenching a bias light as a light output D. By mixing a light output D and light output C of such an optical power in an optical coupler 3, the average optical power in the silence condition E1 and the average optical power in the signal condition E2 are approximately the same in a mixed light output E. Thus, the optical data link having a small pulse distortion, hard to receive the influence of drifting and having high performance can be realized at a low cost.

Title: Ic card
Inventor: KOBAYASHI SUKENORI
IPC: G06K19/073
Filed: 1988-11-09
Abstract: PURPOSE:To obtain a high security function by converting a character string indicated in file identification corresponding information into file identification information designated by the file identification corresponding information when the character string is inputted after the file identification corresponding information is received. CONSTITUTION:When an external processor 2 accesses the file of an IC card 1, the processor 2 sets an arbitrary character string composed of one character or more corresponding to the file name of the file to be accessed to a storing and converting part 10 as file name corresponding information before the processor 2 accesses the file. When the storing and converting part 10 receives the file name information to indicate the correspondence relation of the file name from the external processor 2, and the character string is sent from the processor 2 to the part 10 afterward, the storing and converting part 10 converts the character string into the designated file name. Since the file designation between the IC card 1 and its external part is executed using the set character string, the use of the actual file identification information stored in the IC card 1 is suppressed to the minimum necessity. Thus, the safety of the IC card 1 can be improved.

Title: Deciding apparatus for sealed state
Inventor: IIZAWA HARUMICHI
IPC: G01M3/36
Filed: 1989-10-31
Abstract: PURPOSE:To decide accurately and quickly a hermetically sealed state of a bag having an electric component sealed hermetically therein, by putting the bag in an airtight vessel having an openable cover in a part, by making it vacuum and by determining the hermetically sealed state of the bag from the presence or absence of inflation of the bag. CONSTITUTION:When an instruction on opening or closing of a cover 6 is given to an opening-closing device 13, the device 13 is made to contract and thereby the end part of a connecting shaft 8 is lowered through the intermediary of a crevice 11 and a pin 12. At this time the shaft 8 rotates clockwise around a pin 9 and therefore an airtight vessel 30 is put in an opened state. Next, a bag 24 having an electric component 23 sealed hermetically therein is set on a support 5 and lowered by operating the cover reversely and the vessel 30 is put in an airtight state. A vacuum generating device 19 is made to operate thereafter to make the inside of the vessel 30 vacuum, and when the degree of vacuum reaches a prescribed value, the device 19 is stopped. When the bag 24 is sealed completely, it is inflated by the above operation and pushes up a pusher 20 against a spring 22. When the movement of the pusher 20 is detected by a sensor 17, accordingly, the state of the bag 24 can be decided to be good, and when the state is bad, the pusher 20 is left pushed down. Therefore no output is generated in the sensor 17 in this case.
