  • Patent number: 8540917
    Abstract: An insert molding method includes holding a plurality of insert members in a molding die to be separated from one another, and subsequently filling a resin into the molding die to fill a gap between the insert members and a periphery thereof with the resin to form an insert molded product such that the insert members are separated at a preset interval from one another. The molding die includes a space-maintaining projection for maintaining a separation interval between the insert members at the preset interval or more, the projection being formed on an inner wall surface of the molding die opposite to a longitudinal end of the insert members, and a gate for filling the resin therethrough into the molding die, the gate being formed on an inner wall surface of the molding die opposite to a side of the insert members in a width direction thereof.

  • Patent number: 8395474
    Abstract: A position sensor cord includes a hollow insulator formed of a restorable rubber or a restorable plastic, and two linear resistive members. Each of the two linear resistive members includes a linear insulator and a conductive layer provided around a circumference of the linear insulator. The conductive layer is formed of a conductive rubber or a conductive plastic. The two linear resistive members are arranged in no electrical contact with each other and along an inner surface of the hollow insulator. One of the two linear resistive members may be replaced with one linear conductive member.

  • Patent number: 8299807
    Abstract: A foreign objection detection sensor has a lengthy sensor part having a sensor electrode having a first sensor electrode which detects a proximity of a foreign object and a second sensor electrode which detects a contact of the foreign object, a sensor terminal part provided at one end of the sensor part, a leading wire pulled out from the sensor terminal part, the leading wire being electrically connected to the sensor electrode at the sensor terminal part to provide a proximity detecting function for detecting the proximity of the foreign object to the sensor part and a contact detecting function for detecting the contact of the foreign object to the sensor part. The sensor terminal part has a support member which supports a detection circuit unit electrically connected to the sensor electrode to carry out the proximity detecting function and the contact detecting function together with the sensor electrode. The detection circuit unit is disposed in the support member.

  • Patent number: 8242370
    Abstract: A device-cable assembly integrally molded with a resin according to the present invention comprises: the electric/electronic device; the cable including: a cable sheath which is the outermost layer of the cable, the cable sheath being made of a mixture of a fluorocarbon-based polymer and a polyolefin-based copolymer, and fine silica particles that are deposited on the surface of the cable sheath by CCVD (combustion chemical vapor deposition); and the molded resin which integrally covers the electric/electronic device and the cable together, the molded resin being made of a polyamide-based resin.

  • Patent number: 5045904
    Abstract: A small and reliable semiconductor device is provided in a substrate which has an isolation trench and a capacitor trench. The isolation trench isolates a bipolar transistor from other semiconductor devices, and the capacitor trench provides capacitance to a memory cell which is formed in the substrate. The interior of the device isolation trench is kept in a floating state with respect to the surrounding semiconductor regions by forming an insulating film over the inner surface of the trench. In the capacitor trench, insulating layers and resilient conductive layers are formed alternately to form capacitance between the opposing conductive layers.
