A porous element containing a fluoropolymer comprising vinylidene fluoride as a main unit and having a density of 0.55&#x2013;1.30 g/cmand a Gurley value of not more than 150 sec/100 cc is used as a polymer substrate of a solid electrolyte to be placed between a positive electrode and a negative electrode. As a result, the solid electrolyte layer shows fine ion conductivity and an ion polymer secondary battery having strikingly improved low temperature characteristics, cycle characteristics and high-rate discharge characteristics as compared to conventional batteries can be obtained.

A safety device detects when a worker's hand enters a hazardous region between rollers of a kneading machine, and stops rotation of the rolls to prevent an accident. Each time the rollers are stopped, the orientation of photoelectric sensors is switched from the vicinity of the gap between the two rollers to a test reflection member, and the quantity of received light is compared to a predetermined value, to prevent workers form starting work without knowing a fault or accident has happened. More specifically, a bar electrode of an electrostatic capacitance sensor is disposed above and near the gap between the two rollers, for detecting a physical quantity that is changed by entry of a worker's hand. When the electrostatic capacitance detected by the sensor exceeds a predetermined value, a judging circuit supplies a control signal to stop a driving unit that operates the kneading machine. Heat ray sensors or photoelectric sensors may be used as alternatives to electrostatic sensors. As an additional feature, case housing light projectors and photoelectric sensors are rotatably disposed above and near the gap between the two rollers, and a test reflector is disposed on the side of the case. When the rollers are stopped, a light receiving object switching circuit rotates the case and a test circuit tests the light receiving states of the photoelectric sensors.

A conductor foil laminated on a carrier tape via a sticking layer is stamped out so as to form cut lines on boundaries among a wiring pattern part, a first conductor remainder part forming an outer region enclosing the wiring pattern part, and a second conductor remainder part other than the wiring pattern part and the first conductor remainder part. Next, out of the conductor foil, only the first conductor remainder part is peeled from the carrier tape, and then a first insulating tape with an adhesive layer which is in a solid state at an ordinary temperature is laminated on the carrier tape. Only a region of the adhesive layer with which the wiring pattern part is covered is heated with compression by a lower hot plate so that the wiring pattern part is adhered to the insulating tape. Then, the carrier tape is peeled from the insulating tape so as to be separated therefrom at a steep angle and the second conductor remainder part at a non-adhesion state is removed. Finally, the second insulating tape is laminated on the first insulating tape and the resultant thus obtained is punched into a desired figure. In the step of adhering the wiring pattern part in a transferring step, the laminated tape is disposed in a chamber and is heated with compression under a reduced pressure, thereby preventing air bubbles from entering an interface between the wiring pattern part and the first insulating tape.

A plurality of cores of a multi-core cable are collectively conducted at first ends side thereof and are isolated from one another at second ends side thereof. The cores are engaged at the first ends side with grooves formed on a movable member one by one so as to be picked up and are sequentially transported toward an electrode. The picked-up core is cut during :its transportation so as to be electrically separated from a collective conducting part at the first end side. A high voltage is charged to the picked-up core through the electrode and based on an electric conduction characteristic of its charging current a judgment is made about whether there is a defective contact (dielectric breakdown) between the picked-up core and other cores. Further, the electric charge of the picked-up core is discharged, the picked-up core is recharged, and based on electric conduction characteristics of these discharging current and charging current a confirmation that the above judgment was not a misjudgment is made. After the discharging, the movable member is moved again and then the next picked-up core is tested.

Method and apparatus for electrically testing multi-core cable

Apparatus for assembling a grommet and a wire ring for forming a peripheral reinforcement of an engine head gasket opening. Grommets and wire rings are supplied one by one on different supply devices and retained at first and second article retaining positions, respectively. A movable head moves toward the second retaining position and picks up a wire ring. The head then conveys the wire ring to the second retaining position, where the wire ring is placed overlappingly on the grommet. Thereafter, another movable head having a deforming die is moved against the overlapped grommet and wire ring and deforms a flange of the grommet radially outwardly, whereby the grommet prevents separation of the wire ring therefrom. The thus assembled grommet and wire ring are conveyed to a machine for attaching them to the gasket.

An apparatus for electrically testing a multi-core cable comprises a pick-up unit (6) for picking up a core separately on a one by one basis from a group of cores (101) at one end of the cable (100). Conductor wires of all of a plurality of cores (101) of a cable are collectively rendered conductive by a contact grip (25, 25') at one end of all the conductor wires the opposite ends of which are immersed into a conductive liquid (41) in a vessel (39) at the other end of the cable. The conductor wire of the picked up core is electrically separated from the other cores and power is supplied to the picked up conductor wire so that a current flows through the picked up wire, the conductive liquid, the conductor wires of other cores and through the contact grip to ground. A determining circuit (300) determines in response to the current that the picked up core is in a discontinuity state when the current is smaller than a first value and that an insulation breakdown has occurred between the picked up core and any other core of the cable when the current is larger than a second value which larger than the first value. Thus, both a discontinuity test and a defective insulation test are carried out simultaneously by the present apparatus.

Apparatus and method for electrically testing multi-core cables and

A method and an apparatus useful for a group of wires, such as a telecommunication cable including a multiplicity of cores, as when the wires are individually tested for continuity or defective contact. The group of wires are pressed against the outer periphery of a rotating disc formed with a suitable number of notches each dimensioned to accommodate one wire and are forced into the notches one by one while the disc or the wires are being rocked longitudinally of the wires. The wires individually received in the notches are transferred by the rotation of the disc while being confined in the notches by a confining member provided around the disc and facing the outer periphery as slightly spaced apart therefrom. Thus the group of wires can be separated and transferred one after another reliably, efficiently and automatically.
