  • Patent number: 11679667
    Abstract: The disclosure provides a refueling port capable of simplifying a structure for restricting rotation of a nozzle guide with respect to a refueling port body. One of the refueling port body and the nozzle guide includes guide ribs formed between an inner peripheral surface of a body cylinder portion and an outer peripheral surface of a guide cylinder portion to sandwich a reflux port in the circumferential direction, and guiding fuel vapor flowing in from the reflux port in a direction toward a filler pipe connection port. The other one of the refueling port body and the nozzle guide includes a locking portion formed between the inner peripheral surface of the body cylinder portion and the outer peripheral surface of the guide cylinder portion, and locked in both directions in the circumferential direction to the guide ribs to restrict relative rotation between the refueling port body and the nozzle guide.

  • Patent number: 10596742
    Abstract: A manufacturing process for filler tube includes: a workpiece arrangement step of arranging a workpiece onto an outer peripheral mold not only to axially lock a to-be-locked portion with respect to a locking portion but also so as to make the outer peripheral mold, which is set at a predetermined temperature, support a cylinder-shaped body of the workpiece on the outer peripheral face; and a flare-molding step of flare molding a flange by inserting an inner peripheral mold, which is set at a higher temperature than the predetermined temperature of the outer peripheral mold, into a to-be-molded portion on the inner peripheral side, and by relatively moving the outer peripheral mold and the inner peripheral mold in the axial direction to make a counter-welding-face forming portion and a welding-face forming portion clamp the to-be-molded portion between them in the axial direction.

  • Publication number: 20180304741
    Abstract: A filler tube including a cylindrical body and flange is manufactured using a cylindrical workpiece. A material forms an outermost layer in the cylindrical body and flange of the cylindrical workpiece. Dividable molds move at a first speed upon adhering the cylindrical workpiece onto the site for forming the cylindrical body, thereby giving the cylindrical body a predetermined diametrical thickness; and then move at a second speed being slower than the first speed upon adhering the cylindrical workpiece onto the other site for forming the flange, thereby filling up the flange with the material and other materials for forming the flange over a diametrical range to be welded onto the fuel tank while making the diametrical thickness of the flange greater than that of the cylindrical body.

  • Patent number: 8650971
    Abstract: A simply-structured initial slippage detection mechanism. When a contact member comes in contact with a contact receiving member via a pressure-sensitive conductive sheet, it is confirmed, on the basis of a change in resistivity of the pressure-sensitive conductive sheet and in response to a detection signal transmitted from the pressure-sensitive conductive sheet, that initial slippage has occurred right before the occurrence of slippage displacement, at a time when a high-frequency waveform component generated right before the occurrence of the slippage displacement of the contact member exceeds a predetermined threshold value. Therefore, it is possible to realize a slippage detection device whose slippage detection section is smaller, more lightweight and thinner.

  • Patent number: 8490501
    Abstract: A complex sensor comprises a touch sensor and a proximity sensor. The touch sensor comprises a flexible pressure-sensitive sheet covering a fingertip portion. The pressure-sensitive sheet comprises a front surface film and a rear surface film composed of a flexible conductive material, an intermediate film which is sandwiched between the films in a state in which the intermediate film is electrically connected and which is composed of pressure-sensitive conductive rubber, and first to fourth electrode terminals formed on the front surface and rear surface films. The size of a load acting on the pressure-sensitive sheet and the center position of the load can be detected based on the terminal voltage. A through-hole is formed in the pressure-sensitive sheet such that the sensing surface of the proximity sensor is exposed, thus the approach of a holding object can be detected.

    Abstract: What is proposed is simply-structured initial slippage detection means. When a contact member (5) comes in contact with a contact receiving member (2) via a pressure-sensitive conductive sheet (3A), it is confirmed, on the basis of a change in resistivity of the pressure-sensitive conductive sheet (3A) and in response to a detection signal (S1) transmitted from the pressure-sensitive conductive sheet (3A), that initial slippage has occurred right before the occurrence of slippage displacement, at a time when a high-frequency waveform component (VpX) generated right before the occurrence of the slippage displacement of the contact member (5) exceeds a predetermined threshold value. Therefore, it is possible to realize a slippage detection device whose slippage detection section is smaller, more lightweight and thinner.

  • Patent number: 7784362
    Abstract: For manufacturing a sensor covering a free-form surface, detection elements in which the electric resistance between a first electrode and a second electrode varies when a load is acted on, and cables 12 connecting the adjoining detection elements are provided. Each cable 12 connects a first electrode 21 of a first detection element 11-(i, j) to a first electrode 21 of a second detection element 11-(i+1, j) via first resistances 32-1 to 32-4, and connects a second electrode 22 of the first detection element 11-(i, j) to a second electrode of the second detection element 11-(i+1, j) via second resistances 32-5 to 32-8. The cables 12 can be deformed. The two dimensional load distribution center position detection sensor 2 can cover a free-formed surface. This sensor is easy to manufacture because an elaborate sheet-shaped resistor is not needed.
