  • Patent number: 11148352
    Abstract: A pipe-forming apparatus with which a spiral pipe can be formed using a simple configuration without an inner periphery restriction body. A driving part (10) of a pipe-forming apparatus (3) presses a following strip portion (92) toward a pipe end portion (91e) of a preceding spiral pipe portion (91) obliquely with respect to a machine-height direction HD. A pipe end guide is constrained in a machine-width direction WD with respect to the pipe end portion, and slidably engaged in a propelling longitudinal direction LD. A pressing force for the following strip portion provides a fitting force between the following strip portion and the pipe end portion, and a propelling force for forward propulsion. A pipe is formed in a state where a part other than a partial part at which the pipe-forming apparatus is provided in a circumferential direction of the pipe end portion is released from the pipe-forming apparatus.

  • Patent number: 11015757
    Abstract: The present invention provides a pipe-making apparatus and a pipe-making method capable of making a spiral pipe variably adjusting a diameter or a perimeter of the pipe without an inner periphery limiter. An edge 94 of a following strip portion 92 of a strip member 90 is fitted with a corresponding edge 93 of a preceding pipe portion 91 preceding by one turn by a pipe-making part 3a of a pipe-making apparatus 3, the following strip portion 92 following the preceding pipe portion 91 precedingly made into the spiral pipe, the following strip portion not yet made into the pipe. The pipe-making apparatus 3a is propelled along a spiral winding direction accompanying the fitting. A position 9q of the fitting is variably adjusted by a fitting height adjuster such as an operating lever 30 in a machine height direction HD or a pipe inside-outside direction VD.

  • Publication number: 20210129417
    Abstract: It is possible to prevent a tip portion of a guide portion in a spiral pipe-forming apparatus allowing an inner periphery restriction body to be omitted from colliding a peripheral surface portion of a non-circular existing pipe. A non-circular guide portion (73) is provided so as to be rotatable with respect to an apparatus frame (3a) around a rotary axis (32). The guide portion (73) is applied to a peripheral surface of a preceding spiral pipe portion (91). An acting portion (41) acts such that the guide portion (73) follows the peripheral surface of the existing pipe (1).

  • Publication number: 20210129418
    Abstract: Both diameter expansion and contraction control and fitting stabilization are achieved at the same time in a pipe end release-type pipe-forming apparatus having a non-inner periphery restriction structure. A driving part (10) provided in an apparatus frame (30) of a pipe-forming apparatus (3N) presses an unformed following strip portion (92) of the strip member (90). A reverse side guide portion (83) is engaged with a pipe end portion (91e) of a preceding spiral pipe portion (91) from a reverse side. A face side guide portion (82) is engaged with the pipe end portion (91e) from a face side. The face side guide portion (82) is shifted to the propulsion rear side beyond the reverse side guide portion (83). The following strip portion (92) is extruded from the driving part (10) toward an inter-guide clearance (84) between the reverse side guide portion (83) and the face side guide portion (82).

  • Patent number: 10920918
    Abstract: A spiral pipe (9) is formed by joining edges of adjacent turns of a strip member (90) while helically winding the strip member using a pipe-making apparatus. A propulsive reaction force for moving in a winding direction of the strip member is imparted to a following strip portion (92) or a preceding spiral pipe portion (91) of the strip member by a propulsive reaction force imparting portion of the pipe-making apparatus. The following strip portion follows a preceding spiral pipe portion that has already been made into a pipe. A resisting force in a direction opposite to the propulsive reaction force is imparted to the strip member along the winding direction by a friction between a resisting force imparting portion and the strip member generated while the strip member is moved forward. In this arrangement, a diameter limiting frame can be omitted, and thereby, the pipe-making apparatus can be downsized.

  • Publication number: 20160131278
    Abstract: There is provided a plurality of support members (1) in an existing pipe (101) to form a rehabilitating pipe (102). Each support member (1) includes an arcuate plate (2) that, with a substantially semicircular cross-section, has an inner diameter corresponding to the outer diameter of the rehabilitating pipe (102), so that the arcuate plate (2) is fixed to the upper half portion of the inner surface of the existing pipe (102). The rehabilitating pipe (102) is formed by spirally winding an elongate profile strip while pressing the side edges of the profile strip together from the inside thereof to join the side edges together so that the profile strip is in contact internally with the arcuate plate (2).

  • Patent number: 8126064
    Abstract: The identification information processing unit receives identification information identifying the reception device from a reception device, and generates decoded identification information indicating the decoded value of the received identification information. The parameter value selection unit selects the first parameter value when the decoded identification information includes an information representing a television, selects a second parameter value that is less than the first parameter value when the decoded identification information includes an information representing an audio device, and generates a selected parameter value. The frequency divider frequency divides the audio clock using the selected parameter value, and generates a frequency division signal. The counter counts one period of the frequency division signal using the pixel clock and generates the cycle time stamp. The transmission device then sends the selected parameter value and cycle time stamp to the reception device.

  • Patent number: 7648737
    Abstract: The present invention provides a stretched laminate film with oxygen-gas barrier properties which includes a layer (a) formed from a composition of a polycarboxylate-based polymer (A) and a plasticizer (B), a layer (c) containing a multivalent metal compound (C) and a layer (b) formed from a thermoplastic resin, which film includes at least one layer forming unit where the layer (a) and the layer (c) are adjacent to each other, and in which film at least the layer (a) and the layer (b) are stretched with a surface stretch ratio of 1.1 to 100. By means of carrying out an applying step and a stretching step according to a production method of the present invention, the layer formed from the polycarboxylate-based polymer including the plasticizer can be made thinner, although making the layer thinner has been difficult to achieve as long as only the application is carried out.

  • Publication number: 20090292377
    Abstract: This audio output device can output audio signals with mutually different numbers of channels through multiple audio output sections on a channel-by-channel basis. The device has a first audio output mode for outputting a first audio signal with a first number of channels through the audio output sections and a second audio output mode for outputting second and third audio signals with second and third numbers of channels, respectively, which are both smaller than the first number, through the audio output sections simultaneously. The audio output sections for use to output the second and third audio signals in the second audio mode are used in the first audio mode to output the first audio signal.
