Title: Composite error correction bch decoding circuit
Inventor: YAMAGISHI ATSUHIRO
IPC: H03M13/17
Filed: 1989-05-15
Abstract: PURPOSE:To obtain a composite error correction BCH decoding circuit with higher reliability by providing an output selection circuit incorporating the selection reference of outputs of a random error correction section and a burst error correction section. CONSTITUTION:The state of a communication line is recognized by using the decoding result of a burst error correction section 5 by burst trapping and the decoding result of a random error correction section 7 having a deciding circuit for the calculation result of an integer number arithmetic circuit taking 2<n>-1 as a modulo to give concretely the reference discriminating the state of the communication line, thereby controlling an output selection circuit 6. Thus, the possibility of applying correction in error is decreased and a syndrome generating circuit 2 extracting the error state is shared for a burst error correction section 5 and a random error correction section 7 by providing a means 4 for syndrome conversion.

Title: Method for treating crossing yarn on knitting
Inventor: TAKEGAWA YUJIRO
IPC: D04B1/00
Filed: 1994-05-12
Abstract: PURPOSE:To prevent the wrong knitting of a crossing yarn and the entanglement of the crossing yarn with a needle for the knitting without using a special device and without performing a tucking operation hindering a yarn-removing work. CONSTITUTION:In the method for knitting yarns into a multi-colored single knitted fabric with a weft-knitting machine having two needle beds 1a, 1b, at least one of needles corresponding to a yarn section becoming a crossing yarn among needles 2b held in the needle bed 1b not related to the knitting of the knitted fabric is driven to catch the crossing yarn, when the yarn becoming the crossing yarn 3 is fed, and the needle is then backward moved until other yarns are knitted in at least the section of the crossing yarn. The caught crossing yarn is thus shunted from the movement region of a needle 2a relating to the knitting of the knitted fabric.

Filed: 1992-05-15
Abstract: PURPOSE:To relieve the load of an input work by a user for an attribute of a word by estimating the attribute of the word from morphological information of the word in the case of registering the word to a dictionary. CONSTITUTION:A part of speech estimate section 2 refers to an intelligent database 5 for a part of speech of a word through a communication line 25 to estimate a part of speech of the word received from a word input section 1 and sends the estimated part of speech to an estimated part of speech display section 3 through a communication line 23. The estimated part of speech display section 3 displays the estimated part of speech for the user and sends the estimated part of speech to a word attribute information input section 4 through a communication line 34. The word attribute information input section 4 treats the received part of speech as a default and registers a part of speech when it is newly inputted by the user or the default part of speech when not inputted newly to a dictionary 6 through a communication line 46.

Title: Photo-acoustic gas detector
Inventor: INOUE KOUJI
IPC: G01N29/00
Filed: 1978-10-06
Abstract: PURPOSE:To make it possible to accomplish the highly sensitive and continous measurements by composing a photo-acoustic cell of a resonant tube having a microphone and an expansion chamber connected to each side and by inserting an acoustic filter midway of a tube for leading sample gases. CONSTITUTION:A resonant tube 2 has a length L substantially equal to v/2f (wherein v stands for a sound velocity and f stands for a resonant frequency). As a result, if an incident laser beam 4 is modulated with a chopper 3 which is vibratory at the frequency f, resonance takes place in the tube 2 and is detected by a microphone 1 which is disposed at the center of the tube. A photo-acoustic cell is composed of the tube 2 and expansion chambers 5 and 6 which are formed with incident and emanting apertures for the laser beams at the both sides. These chambers 5 and 6 acts as the passages for sample gases and function to prevent noises from stealing from the outside into the tube 2. Conduits 11 and 12 for quiding the sample gases into the photo-acoustic cell are connected with the chambers 5 and 6, and the pipes 11 and 12 are connected with expansion tubes 9 and 10 having a length of L/2. By the filter actions of the combination of the pipes 9, 10 and the pipes 11, 12, the external noises having a frequency f are reflected so that little of them enter the inside.

Abstract: PROBLEM TO BE SOLVED: To retrieve a program which a user desires without omission by retrieving static PTy and dynamic PTy on a program type which the user designates. SOLUTION: The user designates a PTy to which he desires to listen. A DAB system microcomputer 14 of a radio receiver for digital audio broadcasting(DAB) 10 recognizes the program type (static PTy) of the overall services of DAB or the program type (dynamic PTy) of the program that the service at that time causes to broadcast. It is judged whether static PTy matches with the PTy which the user designates. When they do not match, it is judged whether dynamic PTy matches with the PTy which the user has designated. Then, matched service is outputted from a loudspeaker.

Abstract: PURPOSE:To increase an active material per unit volume and improve conductivity, by enveloping an electrode plate, shaped in a lattice of no frame and filled with an active material, by using a bag-shaped retainer. CONSTITUTION:A positive and negative grid 5 is shaped in a lattice of no frame, with the whole surface area or the most part excluding the lugs in the grid being filled with an active material 2. The whole surface area excluding the lugs in the electrode plate is then enveloped in a bag-shaped retainer 4. Hence, the most part of the lattice comes in contact with the active material, and a utility factor of the active. material is increased with a collector area being enlarged. Structure of no frame allows the amount per unit volume of the active material to be increased together with a rise in capacity. Because the active material is also wholly enveloped in the retainer, its drop accompanied by short circuit can be prevented.
