In a vehicle key device, when a key is inserted into a lock, the former is magnetically coupled to the latter so that data are transmitted therebetween, and only when the data provided by the lock and key correspond with each other is the driving of the engine permitted. This device positively prevents the driving of a vehicle by an unauthorized person.

An apparatus for automatically changing cans of a spinning machine, such as a drawing frame or a carding machine. The apparatus comprises: a movable support frame which can be reciprocated along the can transporting direction; and a plurality of can transporting arms which are substantially equidistantly arranged on the support frame and which can alternately be located at operating positions where the arms transport the cans and stand-by positions where the arms do not interfere with the cans, whereby, when the movable support frame is moved forward, the can transporting arms are maintained at the operating positions so as to transport the cans, and then, after the can transporting arms are returned to their stand-by positions from their operating positions, the support frame is moved backward. The apparatus is characterized in that it further comprises an arm height adjusting member by which individual heights of the can transporting arms in the operating positions where the arms are abutted with the cans are adjustable while the can transporting arms in the stand-by positions are almost at the same level as each other.

Method and apparatus for stopping a flyer frame at the time a roving breakage occurs in an outer layer of any roving package during the spinning operation thereof. When such roving breakage occurs, an abnormal amount of floating flies separated from the broken end portions of the roving scatter in the space between the twisting and winding mechanisms. Such abnormal amount of flies interrupt a light beam emitted from a light emitter, disposed at a position adjacent to and outside one end of the alignment of the twisting and winding flying mechanisms, toward a light receiver, disposed adjacent to and outside, but at the other end, of said alignment. When such interruption occurs the light receiver issues a signal indicating the interruption of the light beam to a power supply relay via a particular control circuit which identifies the abnormal amount of floating flies from the usual amount of floating flies. Therefore, when the control circuit identifies the signal corresponding to the abnormal amount of floating flies, the signal issued from the light receiver actuates the power supply relay so as to stop the flyer frame.

A low-cost leak sensor that prevents leakage current from flowing between electrodes when moisture is deposited. A leak sensor is formed on an insulating substrate. The leak sensor has a through hole having a pair of opposed walls with a predetermined space. The opposed walls are provided with conducting films. On the opening of the through hole in the insulating substrate, a pair of lands are connected electrically with the pair of conducting films. A pair of wiring patterns are connected electrically with the pair of lands on the insulating substrate.

For improving both coplanarity and bending accuracy of gull wing type outer leads of electronic parts such as resin molded semiconductor devices, quad flat packages, etc., a lead forming machine is used which incudes a bending die and a stripper which have a pair of faced projections at both sides thereof, and bending punches vertically moving through perforations of the stripper. An electronic part with gull wing type outer leads is disposed between the bending die and the stripper in such a manner that the outer leads extend horizontally from the projections of the bending die. In this case, both sides of outer leads are placed on projections of the bending die without clamping them with the faced projections of the bending die and the stripper. The bending punches are depressed through perforations of the stripper to perform primary lead forming for the outer leads. Thereafter, the bending punches are further depressed to carry out secondary lead forming for the outer leads, while clamping flat portions of outer leads with the faced projections.

An apparatus for depositing sliver into a sliver can is comprised of a rotary turntable for supporting a sliver can. A cylinder having a piston slidable therein is vertically disposed beneath the center line of the turntable. A pressing rod is connected to the piston and a pressing plate is rotatably mounted on the top end of said pressing rod for engagement with a bottom plate of the can which is freely supported therein. An axial lost motion connection is provided between the pressing plate and the pressing rod and a coil spring is connected between the turntable and the pressing rod to couple the turntable and pressing rod plate together for rotation and for urging the turntable and pressing plate apart.

A reciprocating pump having: a pump body including a suction path and a discharge path for a fluid; a pair of diaphragms; pump shafts which are attached to tip end portions of the diaphragms; a pair of pump flanges which slidably support the pump shafts, and which are integrated with the pump body through connection bodies that are placed outside the diaphragms; connecting rods which connect connecting plates attached to projecting tip-end portions that are projected from the pump flanges in the pump shafts, to each other in a state where the connecting rods are passed through the pump flanges to be placed outside the diaphragms; and a cover cylinder. The connecting rods are slidably supported through slide bearings which are supported by the pump flanges.

An input circuit that detects an abnormality of a voltage generation of the input circuit. The circuit includes an external output terminal, an analog voltage generator. The generator includes a power supply terminal, a grounding terminal, and an internal output terminal. The circuit includes a first resistor, which is connected to the power supply and to the power supply terminal, a second resistor, which is connected to the ground and to the grounding terminal, a third resistor, which is connected to the internal output terminal and to the external output terminal, and a fourth resistor, which is connected to the node of the third resistor and the external output terminal and to the ground. When the grounding terminal or the power supply terminal is open, the analog voltage of the external output terminal is in an upper limit fail voltage range or in a lower limit fail voltage range.

A conductive layer is formed on one surface of an insulating substrate. Notches are formed in the conductive layer to be axially symmetric at equal angular intervals of 120.degree.. A feeding line of a notch antenna is formed on the other surface of the substrate. The feeding line has a C-shape and wide portions for adjusting the phases of excitation of the notches, and receives power at its one point. A ground plate is arranged to be parallel to the substrate. A feeding rod is connected to the conductive layer. The conductive layer and the ground plate are short-circuited by impedance matching pins. The matching pins are integrally formed with the ground plate. The notches and the feeding line constitute an notch antenna, and the feeding rod, the ground plate, the conductive layer, and the matching pins constitute a capacity loaded monopole antenna. To resonate these antennae at a plurality of resonant points, slits are formed in the conductive layer to be axially symmetric at equal angular intervals of 120.degree., and branch lines are connected to feeding lines. The slits resonate the capacity loaded monopole antenna at a plurality of frequencies. The branch lines resonate the notches at a plurality of frequencies. When the number of branch lines, the number of slits, and the like are adjusted, a diversity antenna covering a plurality of bands can be obtained.

A method and device are disclosed for cutting a rove at doffing in a flyer frame, wherein during the normal winding operation thereof the rove drawn out from front rollers is passed through the center hole of a flyer top, the hole of a hollow leg of a flyer, and over a presser and wound on a driven bobbin which is arranged on a bobbin rail moving up and down along the bobbin guide arbor of the flyer. Just before the doffing, the supply of the rove from the front rollers is failed and the bobbin and the flyer are caused to continue rotations substantially at the same speed for a time period sufficient to allow a predetermined number of rotations of both the bobbin and flyer, whereby the rove between the flyer top and the front rollers is subject to a stronger twist than that given during the normal winding operation. This assures that the rove is always cut of itself at an optimum portion thereof at the doffing.
