  • Publication number: 20170299097
    Abstract: A structure of a resin-made pipe joint includes a joint body having a cylindrical shape, a sleeve having a cylindrical press-inserting portion which is press-insertable into the joint body and a cylindrical coupling portion which is press-insertable into a tube, and a fastening member for fixing the tube which is in a state where the coupling portion is press-inserted, to the joint body through the sleeve. The sleeve contains a sealing surface in an outer circumferential surface of the press-inserting portion, the sealing surface being closely contactable with an inner circumferential surface of the joint body, and comprises a non-contacting surface between the press-inserting portion and the coupling portion, the non-contacting surface forming a space with respect to the inner circumferential surface of the joint body, when the sealing surface is closely contacted with the inner circumferential surface of the joint body.

  • Publication number: 20170159854
    Abstract: A resin-made pipe joint enhancing sealing property between a joint body and a sleeve. The joint body and the sleeve are produced by using a fluorine resin. A sealing portion which seals between the inner circumferential surface of an inserting portion of the sleeve and the outer circumferential surface of the inner cylinder portion is formed by press-inserting the inserting portion into a groove portion of the joint body. When, with respect to the inserting and groove portions, an insertion rate of the inserting portion to the groove portion is indicated by X, and a multiplying factor of the radial width of the inserting portion to the radial width of the groove portion is indicated by Y, the resin-made pipe joint has the insertion rate and multiplying factor which are within a range defined by following Expressions (1) and (2): Y=?0.218X+1.218??(1) and Y=?0.67X+1.67.

  • Publication number: 20170146161
    Abstract: A resin-made pipe joint with enhanced sealing property between a joint body and sleeve. A sealing portion which seals between an inner circumferential surface of an inserting portion of a sleeve and an outer circumferential surface of an inner cylinder portion is formed by press-inserting an inserting portion into a groove portion of the joint body. When the inserting portion is press-inserted into the groove portion, a space is formed between a body cylinder portion located opposite to an opening portion of the groove portion in the axial direction, and the projection end of the inserting portion. After completing press insertion of the inserting portion into the groove portion, in a section including axis of the inner cylinder portion, a region in the outer circumferential surface of the inner cylinder portion facing the space forms an angle of 5° to 15° to the axis of the inner cylinder portion.

  • Publication number: 20160278017
    Abstract: A relay apparatus for data relay between multiple communication lines includes a sleep relay unit, a start-up determination unit and a communication block unit. The sleep relay unit relays a sleep instruction that instructs a designated apparatus to transition to a sleep mode. The start-up determination unit determines whether or not a start-up apparatus, which is an apparatus other than the designated apparatus and is in a normal mode, exists in a designated communication line, which is a communication line connected to the designated apparatus. Communication that uses the designated communication line is blocked by the communication block unit when it is determined that the start-up apparatus does not exist in the designated communication line.

  • Patent number: 9346463
    Abstract: During engine startup and engagement of a transmission clutch in response to an EV?HEV mode-switch demand, the transmission clutch is engaged, which precedes initiation of self-sustaining running by the engine. During the clutch engagement, high engine torque is not input to the transmission clutch, and no large torque differential arises in relation to the torque at the output side of the transmission clutch, which during EV operation is a low value about equal to the low motor torque of an electric motor. Additionally, due to cranking during engine startup, the input/output rotation difference of the transmission clutch is small, and when the transmission clutch is engaged, engagement of the transmission clutch may be carried out with reduced shock, as the input/output torque differential and the input/output rotation difference are small.

  • Patent number: 8861621
    Abstract: In a receiver circuit, a binary signal is generated based on a signal level of a received signal that has been received via a transmission line from a driver of a transmitter circuit. Then, a first stable state and a second stable state are detected based on a reference signal whose signal level changes in accordance with the received signal. In the first stable state, the received signal is stable at a first signal level. In the second stable state, the received signal is stable at a second signal level. When the first stable state is detected and the received signal is changed from the first signal level into the second signal level, the generated binary signal is retained at a signal level corresponding to the second signal level, until the second stable state is detected.

  • Patent number: 8677976
    Abstract: A high pressure fuel pump (20) that pressurizes and supplies a fuel by driving a cam (21) such that a plunger (23) reciprocates, the high pressure fuel pump (20) comprises a lifter guide (25) having a guide hole (25A), a lifter (22) that is disposed between the cam (21) and the plunger (23) and is fitted into the guide hole (25A) to be free to slide so as to transmit a driving force from the cam (21) to the plunger (23), an oil collection portion (27) that is provided above the guide hole (25A) so as to surround a periphery of the lifter (22), and stores a lubricating oil for lubricating a sliding portion between the lifter (22) and the guide hole (25A), and an oil supply passage (25C) for supplying the lubricating oil to the oil collection portion (27). As a result, a reduction in a lubricating performance with regard to the lifter (22) in a position away from an opening portion of the oil supply passage (25C) is suppressed.

  • Publication number: 20060264221
    Abstract: A sensor station (21) installed to a truck (1) receives sensor information transmitted from wireless temperature sensors (32-1) through (32-6) installed inside a container of the truck (1) and stores a temperature variation inside the container during package transportation. When the truck (1) arrives at a delivery center (7), the sensor station (21) transmits data of the temperature variation accumulated in the sensor station (21) to a server (35). A server (20) of an ASP center 2 communicates with the server (35) via the network (4) and obtains the data of the temperature variation. A user (3) accesses the server (20) of the ASP center by a PC (11), a mobile phone (12) or the like, and obtains information on the package temperature variation. The present invention can be applied to a mobile wireless terminal.
