  • Patent number: 9534946
    Abstract: An electrostatic capacitance fluid level sensor includes a hermetic terminal having two terminal pins inserted through a metal base, a detection device including two electrodes for fluid level detection by electrostatic capacitance and two connecting terminals configured to fix the pins to the electrodes respectively. The connecting terminals are formed into such a shape as to include parts parallel to the electrodes and parts orthogonal to the electrodes by bending the terminals at bends, respectively. The parallel parts are fixed to sides of the electrodes opposed to sides of the electrodes facing each other, respectively. The orthogonal parts are fixed to the pins respectively. One of the terminals has a larger thickness than the other thereby to have a sufficient stiffness to hold the detection device. At least one of the terminals is deformable by a weaker force than a force causing the electrodes to deform.

  • Patent number: 9204210
    Abstract: A data relay apparatus R (e.g., one included in an ONU) that performs data transfer from one port to another port reduces power consumption by performing control to limit a receive function of a receiving unit 1 at the one port under at least one of conditions that a control instruction is received from a communication partner (e.g., an OLT) connected to the one port (port 2), and that information about control is notified to the communication partner; and allows the receive function to recover when a predetermined recovery condition is satisfied (e.g., a lapse of a predetermined period of time or arrival of a predetermined time). In this case, since recognition that the receive function is limited can be shared with the communication partner, the communication partner can prevent itself from performing data transmission to the data relay apparatus R when the receive function is limited.

  • Publication number: 20140352429
    Abstract: In an electrostatic capacitance fluid level sensor including fluid level detection electrode plates mounted on conductive pins mounted on a hermetic terminal, a fluid level detection part mounted on the hermetic terminal has a detection unit including two electrodes, electrically insulating spacers fixing a positional relationship between the electrodes, and at least one connecting terminal configured to connect and fix the detection unit to the conductive pins. The connecting terminal is deformable by a weaker force than a force causing the electrodes to deform. As a result, stress applied to the electrodes of the detection unit is dispersed/relaxed. Since the detection unit is further connected and fixed to the hermetic terminal for a motor compressor, a work for mounting the sensor to the hermetic motor compressor can be rendered easier as well as the handling of the sensor.
