IPC: F16L9/12
Filed: 1988-07-22
Abstract: PURPOSE:To improve the pressureproofness, heat resistance, and shock resistance by forming a fiber-reinforced thermosetting resin layer through an adhesive layer containing the unsaturated polyester resin and the isocyanate compounds onto the outer periphery of a core member consisting of a thermoplastic resin pipe. CONSTITUTION:The title composite pipe and composite pipe joint are formed by forming a core member from a thermoplastic resin pipe 1 and forming a fiber-reinforced thermosetting resin layer 3 onto the outer peripheral surface of the core member through an adhesive layer 2. The thermoplastic resin 1 is made of the vinyl chloride resin, polyamide resin, acrylic resin, polycarbonate resin, etc. The adhesive layer 2 is made of the compounds containing the isocyanate group which is obtained by reacting the unsaturated polyester with the isocyanate compounds. The fiber-reinforced thermosetting resin layer 3 is formed by impregnating the unsaturated polyester resin, etc., onto glass fibers. Therefore, the superior heat resistance, pressureproofness, and shock resistance can be secured, and the generation of between-layer exfoliation can be suppressed, and the trouble of buckling, etc., is prevented.

IPC: H04N1/40
Filed: 1984-09-03
Abstract: PURPOSE:To read an original picture with high accuracy at an arbitrary scan line density by providing a reading means for reading picture information, 1st and 2nd sampling means and an arithmetic means for carrying out arithmetic mean of image signals of respective reference read picture elements with respect to the sub-scan direction from the output of the 2nd sampling means. CONSTITUTION:The output of a digital signals correcting device 8 is converted into an analog signal by a D/A converter 10. A image signal applied to an A/D converter 11 is an analog picture signal which has been obtained by the photoelectric transfer with use of one-dimensional solid-state image sensor 4 and is subjected to the corrections such as shooting correction or gradation one. This analog picture signal is again converted into a digital signal by the A/D converter 11. The frequency of the sampling pulse of an A/D converter 7 is decided by the number of picture elements of said sensor 4 and the reading time of one line. However, the frequency of the sampling pulse of the A/D converter 11 is so constituted to be freely set, and the number of read-out picture elements of one line of the frequency can be modified.

Title: Line quality test mechanism
Inventor: IWANAMI TAKASHI
IPC: H04B3/46
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To conduct a quality test of a line between transmitters without the need of a measurement device whose operation is difficult. SOLUTION: A loop line control section 12 forms a loopback loop for an opposite transmitter at the start of a quality test. When the quality test is started, a PN pattern generating section 13 generates a signal-pattern P, the pattern P is looped back by the loopback loop and a PN pattern synchronization section 15 receives the looped back pattern. The PN pattern synchronization section 15 establishes synchronization of a signal received successively based on the result of receiving the signal pattern P. After the establishment of the synchronization, an error bit insert section 14 inserts an error bit to a signal pattern P to obtain a signal pattern P1 and outputs it to the opposed transmitter.  A PN pattern comparison section 16 and a bit number comparison section 17 compare number of the inserted error bits and number E of the error bits in the signal pattern P1 received by the PN pattern synchronization section 15 to conduct the quality test for a line between the transmitters.

Title: Tuyere brick
Inventor: ARAMAKI KEIZO
IPC: C21C7/072
Filed: 1997-06-24
Abstract: PROBLEM TO BE SOLVED: To prevent molten metal leakage caused by the cracking due to heat hysteresis during operation and also spalling caused by the cracking at boundaries by winding an iron shell with a specific range of thickness, for reinforcing, on the outer peripheral surface of a tuyere brick for ladle. SOLUTION: On the outer peripheral surface of a tuyere brick 1, an iron shell 4 having 0.6-2.0 mm thickness is wound and reinforced. The iron shell 4 is wound for reinforcement on the whole outer peripheral surface of the tuyere brick 1 or wound only on a part of the tuyere brick 1. In the case of thickness of the iron shell 4 being <=0.6 mm, the iron shell can not restrain expansion difference due to the heat hysteresis during operation and does not serve to the prevention of development of the crack. Further, in the case of being >=2 mm, a joint part with a bed brick becomes large, and the preceding erosion from the joint part is developed as one factor, and as a result, the danger of molten metal leakage is developed.  This tuyere brick can safely be used without developing the spalling and the molten metal leakage and the durability is largely improved in comparison with the conventional brick.
