Title: Pipe end flaw detection control method and apparatus for automatic flaw detector
Inventor: KONDOU HIROAKI
IPC: G01N29/04
Filed: 1982-07-13
Abstract: PURPOSE:To improve the accuracy and reliability of control of the end of a pipe by such an arrangement wherein a joint of pipes is detected at a point before a flaw detector, and the distance of movement of a steel pipe is detected and when moving distance detection signals deviate from data on a set length of a pipe, joint detection signals are cut off. CONSTITUTION:Plural pieces of steel pipe P1, P2, P3 are arranged in a row with their ends caused to contact each other and they are continuously fed into a ultrasonic wave flaw detector 11. In front of the flaw detector 11, a joint detector 2 is arranged and it detects the top end, rear end or the position of a joint of steel pipes to be fed and generates signals. The flaw detector 11 is also equipped with a distance detector 3 which detects the distance of movement of a steel pipe, and it gives clock signals to a comparison and judgement circuit 5 through a distance counter 4. The circuit 5 compares distance signals from the counter 4 with those from a pipe length setter 6 and gives judgement signals to a signal processing unit 7 and in the vicinity of a joint, it causes signals from the jont detector 2 to pass through.

Title: Air collector
Inventor: SEI MIKIO
IPC: F24S10/50
Filed: 1984-06-14
Abstract: PURPOSE:To contrive to enhance the heat collecting efficiency of the titled collector by a structure wherein the width of recessed beads of an absorber plate, which divides a space into two layers, is made broader near the inlet of air and narrower near the outlet of air. CONSTITUTION:Front side spaces 7 are formed to be wider on the air inlet 5 side and to become gradually narrower in the direction toward the air outlet 6, while rear side spaces 8 are formed to be narrower on the air inlet 5 side and to become gradually wider in the direction toward the air outlet 6. As a result, in the spaces 7, the air speed is low near the inlet 5 and turns to be high near the outlet 6, while in the rear side spaces 8, the air speed is high near the inlet 5 and turns to be low near the outlet 6. Accordingly, the heat transfer rate of air near the inlet 5 is larger in the spaces 7 than in the spaces 8, while that near the outlet 6 is larger in the spaces 8 than in the spaces 7. As for the portion with high air temperature near the outlet 6, the heat dissipation from the absorber plate 4 is profitable in the spaces 8 in connection with heat transfer rate, resulting in suppressing the wasteful dissipation of heat to the spaces 7. In addition, the dissipation of heat of the spaces 7 through a transparent plate 2 becomes smaller due to the decrease of the heat transfer rate, resulting in enhancing the efficiency as a whole.

Abstract: PURPOSE: To prevent curing inferiority or curing shrinkage by allowing a photopolymerization initiator and a thermal polymerization initiator to be together present in a nozzle forming member and curing the member by the start of polymerization by the combination use system of those polymerization initiators. CONSTITUTION: A substrate having a solid layer of nozzle patterns provided thereto is covered with an active energy beam curable nozzle forming member and a lid plate pervious to active energy beam is bonded to the substrate through the member and the member is cured by the irradiation with active energy beam and, next, the solid layer of nozzle patterns is removed to form nozzles. When a photopolymerization initiator and a thermal polymerization initiator are mixed with a liquid passage forming material, the lid plate can be used without being limited to a conventional one suitable for high energy beam and, therefore, the selection width of the lid plate is expanded.  Since satisfactory curing is possible even if conventional high energy beam is not used, even when a filler is added, the non-curing caused by the scattering of energy beam by the filler is not generated and a highly reliable head can be produced.
