Title: Binarizing device
Inventor: TSUJI NOBUHIKO
IPC: H03M1/34
Filed: 1989-01-11
Abstract: PURPOSE:To obtain an accurate binarizing signal without effect of noise by monitoring a difference of signal levels of upper and lower limit envelopes of a photoelectric conversion signal from a paper front with a bar code printed thereupon and adjusting a storage time of the upper limit envelope so that the difference does not reach a specified value or below. CONSTITUTION:Output levels from upper and lower limit envelope circuits 3, 4 are monitored by a differential amplifier 8 and a control means 10. When the level reaches a specified value or below, a switch of the upper limit envelope circuit 3 is turned off to make a storage time of the upper limit envelope close to infinite. Thus, a level of a threshold level signal from a midpoint detection circuit 5 even at a blank of a bar code is set sufficiently higher than a level of a noise signal included in the analog signal. Then an accurate binarized signal not affected by noise is obtained.

Title: Communication system
Inventor: OTERU YOICHI
IPC: H04L69/14
Filed: 1986-01-10
Abstract: PURPOSE:To attain retransmission while the storage capacity and processing quantity of a transmission station are suppressed by allowing the transmission station to divide a retransmission request block from each reception station and to transmit an exclusive OR frame of the first half block to minimize information quantity of an incoming line. CONSTITUTION:The transmission station sends N1-set of information frames J(i) continuously and the N1-set of information frames sent already at the (N+1)-th frame as an exclusive OR frame X(1, N1) at each bit. When a reception station 1 receives J(3), J(5), J(8) and a reception section 2 receives J(1), J(5) and J(8) respectively in error, the reception stations 1-3 return the retransmission request, the transmission station obtains a division M1 to send X(1, 4). Each reception station recovers a reception frame in error as to the J(1)-J(4) to return the normal reception reply. Then the transmission station sends the retransmission frame X(1, 3) of J(5)-J(8). Thus, the transmission station recognizes the normal reception of each reception station.

Title: Production of optical fiber bundle having flexibility
Inventor: HARADA ISATOMO
IPC: G02B6/06
Filed: 1982-01-12
Abstract: PURPOSE:To obtain uniform and flexible optical fibers efficiently, by packing and arranging  triple optical fibers, which consist of a core glass, an acid-proof glass, and an acid soluble  glass, most closely in a hexagonal cylinder-shaped glass overcoat tube, where six inside vertical angles are about 120 deg., and stretching them by heating and pressurizing. CONSTITUTION:Triple optical fibers 1 where a core glass 2 having a high refractive index is  covered with an acid-proof glass 3 having a low refractive index and the glass 3 is covered  with an acid soluble glass are packed most closely in a hexagonal cylinder-shaped glass overcoat tube 22 consisting of an acid soluble glass, a soda lime glass, or the like, where six  inside vertical angles are about 120 deg., to produce an optical fiber bundle 27. The bundle 27 is  heated and pressurized to be stretched, thereby obtaining an optical fiber bundle 17 having a  prescribed diameter. After both end parts of the fiber bundle 17 are coated with acid-proof  resin coatings 20, the bundle 17 is immersed in an acid processing liquid 19 to dissolve and remove the overcoat tube 22 (in case of the acid soluble glass) and acid soluble coatings 4. In  case of the tube 22 consisting of a soda glass, the bundle 17 is immersed in the acid processing liquid 19 to remove coatings 4 after the tube 22 is removed mechanically. Thus, since optical  fibers 4 are arranged without generating uneven gaps in the overcoat tube 22, the unevenness  of the image transmission characteristics due to partial unevenness after stretching is prevented.
