Title: Joining method for resin pipe
Inventor: OYA HIROSHI
IPC: F16L47/02
Filed: 1998-10-02
Abstract: PROBLEM TO BE SOLVED: To prevent the formation of a bead on the pipe inside surface, and to enhance mechanical strength of the joining part by diametrically fixing a cylindrical body and two resin pipes by butting and fusing the mutual resin pipes in a state of inserting the cylindrical body into the resin pipes in an almost central position of the opposed two resin pipe end parts. SOLUTION: The end parts of resin pipes 1, 2 are heated and melted by a heater 3 in a state of inserting a cylindrical body 4 into the resin pipes 1, 2 in an almost central position of the end parts of the opposed two resin pipes 1, 2. The mutual end parts of the melted resin pipes 1, 2 are butted so that the pipe shaft direction coincide with each other, and are butted and joined by pressing the end parts in the axial direction toward a joining place from the respective resin pipes 1, 2. In this butting joining, a pipe outside surface side melting resin protruding when pressed in the axial direction becomes a bead 5, but a pipe inside surface side melting resin does not become a bead, and is filled in clearance between the resin pipes 1, 2 and the cylindrical body 4, so that the cylindrical body 4 and the two resin pipes 1, 2 can be diametrically fixed.

Filed: 1985-12-13
Abstract: PURPOSE:To easily switch the display screen of an alarm message etc., to the immediately preceding display screen again, by storing the contents of the preceding display in a memory in case the monitored action signal, state signal, etc., have the abnormality. CONSTITUTION:A ROM 11 which stores a control program, a RAM 12 which stores various types of coordinate value, a tape leader 13, a CRT 14, a keyboard 15, etc., are connected to a CPU 10. Then the CPU 10 delivers an action command via a position control part 21. Here the input/output of an NC part program is possible as necessary to a nonvolatile memory 16. A RAM 25 stores the contents of display of the CRT 14 while replacing them successively. Therefore the original display of the screen is reset immediately after an alarm message or an operator message is released by a command given from the keyboard 15. This reduces the load of an operator.

Abstract: PURPOSE:To correct variation in frequency characteristics of a sensor with time, and to correctly evaluate whether or not a valve leak is caused and also calculates an accurate leak quantity by providing an oscillation body which is characteristically stable nearby an AE (acoustic emission) sensor. CONSTITUTION:The oscillation body 10 provided nearby the AE sensor 2 installed on a valve 1 is supplied with a white noise signal S from an oscillator 11. Then the output of the AE sensor 2 is amplified and filtered by an AE measuring instrument 3 and a frequency spectrum found by a signal analyzing device 4 is stored in a characteristic adjusting device 12 as an analytic result in an initial state. Then when a certain time is elapsed, the frequency characteristics of the AE sensor 2 is measured and the adjustment gain of the characteristic adjuster 12 is found from the difference from the initial state so that the frequency characteristics are similar to those in the initial state, thereby correcting the characteristic variation of the AE sensor. Then when a leak signal is detected, the analyzed frequency spectrum signal is sent to a processor 5 through the characteristic adjuster 12 to decide whether or not the value 1 has a leak.

Title: Non-contact type shape measuring device
Inventor: TAMADA NORIO
IPC: G01B11/24
Filed: 1992-10-20
Abstract: PURPOSE:To measure a surface shape accurately by detecting distances at two measuring positions apart mutually in an optical axis direction through an optical distance detecting means at respective measuring points, judging whether the measuring points are positioned within a measurable range through the distance detecting means, and computing the shape on proper detected values only. CONSTITUTION:At respective measuring points, the difference of a detected distance at a first measuring position (distance from an optical distance detecting means to a light-irradiated point on an object to be measured) and a detected distance at a second measuring position is computed by a detected value comparing means 44, and a current detected value is judged whether it is proper or not. When the detected value is judged to be proper, the detected value is input to a shape computing means 46. When the detected value is judged to be not proper, a command is sent to a drive control means 42 so as to move the object to be measured in a Z axis direction once again. By the means 46, the surface shape of the object to be measured is computed based on the moved position of the object to be measured determined from the detected results of respective axis scales 24, 26, 28 and the detected value judged to be poper through the means 44, and its result is displayed on a display device 52.

Title: Position detector
Inventor: MASUDA YUTAKA
IPC: G01D5/245
Filed: 1990-10-19
Abstract: PURPOSE:To reduce the errors of a detector due to the eccentricity thereof by providing a first coupling means for supporting and coupling a supporting member by elasticity in the rotating direction around the center of a rotary shaft to a fixed shaft, and a second coupling means for coupling a supporting part by elasticity in the rotating direction around a supporting point of the supporting member and the first, coupling means to the fixed side. CONSTITUTION:A hollow rotary shaft 1 is fixed to a measuring shaft 2 via a fixing means 10. At this time, the amount of the eccentricity of measuring faces 9a, 9b is measured, and the axial center of the means 10 is adjusted so that the center of a code plate 3 agrees with the rotating center of the shaft 2. Accordingly, the detecting errors of the angle resulting from the eccentric rotation of the code plate 3 are less generated. A supporting member 5 is supported by the elasticity of a leaf spring 16 in the rotating direction of the rotary shaft to a fixed shaft 11, and by the tensile force and the deflection rigidity of a piano wire 14 in the other direction than the above rotating direction. Therefore, the supporting member 5 is always supported at the balanced position of the leaf spring 6 to the fixed part 11. Thus, generation of errors at the detecting time can be prevented.
