摘要： PURPOSE:To constitute a joint for thin-walled pipes more easily than by conventional methods by providing an expanded part to the end of the joint body, fitting a packing in its inside annular groove, supporting the expanded part by jigs of a given shape and letting said end part be bitten under pressure into the outside surface of the pipe to be connected. CONSTITUTION:An expanded part 3 is provided at the center of the pipe-inserting part 2 of the end of a joint body 1 by leaving a straight pipe part 5, and a packing 7 is fitted in the annular groove 4 of its inside surface. The expanded part 3 is then supported by the jigs 8, 8' formed with tapered faces 8a, 8a' on its inside, and the leading end of the straight pipe part 5 is pressed in the axial direction so that the edge 6 on the inside-diameter side is bitten into the outside surface of the pipe 10 to be connected. In this way, the straight pipe part 5 of the joint end deforms into arc form and is prevented from being disengaged from the joint body 1 of the bitten pipe 10. This method may be executed more easily than conventional methods and is suited for connection of thin-walled metal pipes.

摘要： PURPOSE:To improve reliability by preventing erroneous stop from being generated again by re-registering the learnt result when the erroneous stop occurs after learning is completed. CONSTITUTION:A flow rate signal G from a flow rate measuring means 1 is calculated into a real flow rate P1 by a flow rate arithmetic part 2. During a prescribed learning term, a learning processing part 3 calculates a flow rate pattern Q as the learnt result and holds it. Further, a flow rate decision part 4 receives the flow rate pattern Q from the learning processing part and a flow rate pattern P2 from the flow rate arithmetic part and compares them and in the case of abnormality, a stop/alarm signal R is outputted. A stop alarming means 5 issues an alarm or stops a gas route. While receiving the signal of this flow rate decision part 4, a stop flow rate storage part 6 stores a flow rate pattern F at the time of stop. Corresponding to an input from the outside, a reregister signal T is outputted by an erroneous stop time reregister signal input means 7. An erroneous stop time reregister processing part 8 instructs the holding of the flow rate pattern F in the stop flow rate storage part 6 to the learning processing part 3 and updates the learnt result.

摘要： PURPOSE:To confirm the state of a device at an external device by mounting an electromagnet, a light emitting diode and a photo transistor(TR) to an external device at a position when the light of the light emitting diode is reflected in a liquid crystal display device and made incident in the photo TR and mounting a reed switch and a liquid crystal display device to the equipment. CONSTITUTION:A microcomputer 1 of an equipment 4 recognizes the state of a reed switch 3 and the equipment is switched according to a switching signal sent from an external device 10. When a data in the microcomputer 1 of the equipment 4 is sent to an external device 10 as a signal, the microcomputer 1 controls lighting/extinguishment of the liquid crystal display device 2. A light from the light emitting diode 5 is reflected in a display face of the liquid crystal display device 2 and the electric output depending on the luminous quantity made incident in a photo diode 8 is amplified by an amplifier circuit 7 of the external device 10 and the microcomputer 9 reads the data and confirms it. Thus, the state of the device 4 is confirmed by other external device 10.

摘要： PURPOSE:To enable the measurement of a flow rate accurately, by performing a corrective computation of a arithmetic processing of a rotor pulse yet to be processed when the unprocessed rotor pulse exists. CONSTITUTION:A turbine rotor 3a is rotated according to a flow rate of a gas to be supplied through a supply line 2 and the rotation of the rotor 3a is detected with a pickup 3b. Then, a signal detected with the pickup 3b is converted into an electrical signal with a detection circuit 4 to be shaped in waveform with a pulsation circuit 5 and supplied to a correction computing circuit 6 and a frequency dividing circuit 7. The circuit 6 is provided with a computation circuit 6a to which a rotor pulse 5' is supplied from the circuit 5 to compute a flow rate and a correction circuit 6b to which a frequency dividing pulse 7' from the circuit 7 is supplied to correct computation/ measurement errors by an a pulse 7' yet to be processed. Thus, the circuit 6 is supplied with the pulse 5' and the pulse 7' to calculate a cumulative flow rate by an arithmetic processing and the results are shown on a display device 8 thereby enabling accurate measurement of the flow rate.

摘要： PURPOSE:To remove distortion which increases and decreases with the distance between an MR element and a magnet and to obtain an output signal waveform having no distortion by forming a couple of bent patterns of a magneto- resistance element successively in the direction of a rotary shaft. CONSTITUTION:A silicon substrate 31which is divided into two is formed on a rectangular package 30, and the bent line pattern RA of a ferromagnetic thin film which is bent zigzag having its lengthwise direction in an X direction is formed on one substrate part. Further, the bent line pattern RB of a ferromagnetic thin film which is bent zigzag having its lengthwise direction in a Z direction is formed on the other substrate part, and both patterns RA and RB are connected with each other. This MR element 40 is fixed opposite the position of a rotary body 20 corresponding to the magnet 24. Consequently, the output waveform of the MR element 40 does not varies even if the distance between the MR element 40 and magnet 24 increases or decreases, so the output waveform having no distortion is obtained.

摘要： PURPOSE:To manufacture a pivot bearing with small holes for supplying lubrication oil efficiently by forming small holes along the axle direction in the central hole of a cylinder member made of metal and push-pressing the end surface of the cylinder member in a recessed shape so as to form a bearing part. CONSTITUTION:A pipe 24 made of metal with a central hole 23 going through in the axial direction and a core metal 25 made of metal with its diameter slightly smaller than the inner diameter of the central hole 23 and its outer circumference formed in a serration shape are prepared. After inserting the core metal 25 into the central hole 23, the pipe 24 is compressed by a swagging process so as to shrink its diameter. Consequently, raised parts 25b on the outer circumference of the core metal 25 are brought in press-contact with the inner wall of the central hole 23 and the core metal 25 is integrated with the pipe 24 in one body so that a compound body 27 can be obtained. Plural compound bodies 28 can be obtained by cutting in a prescribed length l. Then, a central area of the end surface 28a of the compound body 28 is push-pressed by a pressing process so as to form a recessed part 28b. This recessed part 28b becomes a bearing part and small holes 26 opening to this recessed part 28b are opened outside the part where the rotary shaft of the bearing part is put in sliding contact and becomes a communication hole for supplying lubrication oil.

摘要： PURPOSE:To enhance the durability of a bearing part and a rotary shaft and the measuring accuracy of a flowmeter, by providing an oil sump part for storing a lubricant to the deep part of a bearing member. CONSTITUTION:When a fluid flows through the flow passage in a flowmeter main body 2 from below to above the fluid passes while rotates the blades of a blade wheel 11. The leading end 12a of the pivot 12 of the blade wheel 11 slides with a receiving bottom 19a to form a meniscus 23. The lubricant of an oil sump chamber 24 is supplied to the receiving bottom 19a by a small amount by the capillary phenomenon of a communication hole 19b. Therefore, the leading end part 12a of the pivot 12 rotates smoothly and stably in the state brought into contact with the meniscus 23 of the lubricant formed to the receiving bottom 19a. When the lubricant is reduced and the meniscus becomes small, the lubricant in the oil sump chamber 24 is supplied to the receiving bottom 19a by a small amount through the communication hole 19b until the surface tension of the meniscus 23 is well-balanced with the head of a fine tube 26. By this method, not only the durability of the bearing part and the rotary shaft but also the measuring accuracy of the flowmeter can be enhanced.
