Patent number: 4706381Abstract: A multi contact connector includes a ground terminal block and signal and power source terminals connected with tape wires. Bare wires of the tape wires connected to the signal and power source terminals are provided with roundabout portions respectively to form slacks in the bare wires. With this arrangement, when external tensile forces act upon the connector, the slacks prevent disconnection of bare wires for signal and power source terminals indispensable for operation of the connector, even if a few bare wires among a number of bare wires connected to the ground terminal block are disconnected.Type: GrantFiled: May 16, 1986Date of Patent: November 17, 1987Assignees: Daiichi Denshi Kogyo Kabushiki Kaisha, Hitachi, Ltd.Inventors: Matsuo Kato, Tomonari Ohtsuki, Kazuya Hashimoto, Masami Nakaide

Patent number: 4706835Abstract: A closure for a container with a top cut tamper evident feature and including an overcap rotatably attached to a container end portion. The container end portion is provided with an integral, hollow raised annular rib having a first truncated end and a second, inclined end, the two ends separated by a weakened hinge portion. The overcap is provided with a raised, open-bottomed, channel with a first open end and a second inclined end forming a knife blade, the channel overlaying and engaging the raised rib so that when the overcap is rotated, the knife blade severs the rib and moves it up the inclined end. Once the entire rib is severed, the combined container end and overcap may be detached from the container by tearing the hinge. The overcap and closure may be provided with cooperating means to permit the closure to be reattached to the container.Type: GrantFiled: April 16, 1987Date of Patent: November 17, 1987Assignee: Courtesy Mold & Tool CorporationInventor: Walter J.

Patent number: 4704602Abstract: An indicating device (31) of a highly permeable material is detected by emitting and receiving a magnetic field, wherein two coils (1,2) are caused to emit a high-frequency magnetic alternating field, and a first one of the coils (1) emits an alternating field with a frequency (f.sub.1) different from the frequence (f.sub.2) of the field emitted by the second one of the coils (2), and at least one difference and/or sum frequency n.multidot.f.sub.1 +m.multidot.f.sub.2 occurring by intermodulation by means of the indicating device (31), where n and m are positive or negative integers, is caused to be received by one or several coils (9). A third low-frequency magnetic alternating field is caused to be emitted in said zone with a frequency (f.sub.3) substantially lower than the frequencies (f.sub.1,f.sub.2), which low-frequency field has a field intensity sufficiently high, independently of the fields with the frequencies f.sub.1 and f.sub.Type: GrantFiled: October 1, 1985Date of Patent: November 3, 1987Assignee: Intermodulation and Safety System ABInventor: Leif Asbrink

Patent number: 4704669Abstract: A ring surrounding the clip which secures the body of an LED diode lamp to a bracket is provided with inner longitudinal grooves which reduce the thickness of the wall of the ring and confer thereto an elasticity which is sufficient for permitting its engagement on clips of different diameters. The manufacture of diode lamps does not provide the bodies of these lamps with very precise or consistent diameters, so that relatively important variations of these diameters can occur, which have an influence on the diameter of the clip when engaged on the lamp. Owing to the present arrangement, diode lamp holders can absorb such variations of diameter of the lamps, and still be secured to a panel or other structure by the ring of the invention.Type: GrantFiled: September 12, 1986Date of Patent: November 3, 1987Assignee: Universo S.A.Inventor: Jean Brunner

Patent number: 4700625Abstract: A needle-carrying head for a printing machine has needles controlled by electro-magnets. The coils of the electro-magnets are soldered to pins carried by support ears for the coils. The pins pass through printed circuit boards to which they are soldered. The coils are engaged on cores constituted by limbs of respective fork-shaped members the second limb of which serves to complete the magnetic circuit. The two limbs of each fork-shaped member are interconnected by means of a transverse portion constituting a yoke, secured by setting into one or the other of two plates forming, with a central plate made of plastics material, a cage-shaped frame of the needle-carrying head. The printed circuit boards are thus interposed between the electro-magnets and the front plate of the frame on the one hand, and between the electro-magnets and the rear plate on the other hand.Type: GrantFiled: October 16, 1985Date of Patent: October 20, 1987Assignee: Caracteres S.A.Inventor: Eric Bauer

Patent number: 4696410Abstract: A tamper evident closure for a container having a closed endcap with an overcap to coaxially rotate thereabout. The overcap is provided with an integrally formed knife blade which is constructed and arranged to engage a weakened annular band in the container wall near the endcap. The knife blade is located within a well which is an integral part of the overcap. As the overcap is rotated, the knife blade engages and severs the annular band, and separates the closure including the endcap and the rotatable cap from the body of the container. An annular channel may also be provided to support the overcap during rotation and thus maintain the alignment of the blade with the weakened annular band.Type: GrantFiled: March 26, 1987Date of Patent: September 29, 1987Assignee: Courtesy Mold & Tool CorporationInventor: Walter J. Kreiseder

Patent number: 4695914Abstract: An electronic card connecting circuit comprises a first contact pin for earthing a ground terminal of an electronic card, a second contact pin for electrically contacting the ground terminal to detect the ground terminal being earthed by the first contact pin, and detection control means including an active element which detects the second contact means being connected through the ground terminal to the first contact pin and controls a power source circuit to supply power to the electronic card. With this arrangement, when the first and second contact pins are in contact with the ground terminal of the electronic card, the detection control means detects the second contact pin being earthed to produce a control signal to apply power of source to the electronic card. In this manner, before the ground terminal of the card is earthed, the power source is prevented from being connected to the electronic card.Type: GrantFiled: August 22, 1986Date of Patent: September 22, 1987Assignee: Daiichi Denshi Kogyo Kabushiki KaishaInventors: Tomonari Ohtsuki, Kazuyoshi Tsurumaki

Patent number: 4687309Abstract: A device for transporting a camera and for reducing camera shake and arm fatigue by stabilizing the camera against the torso of a person. The device includes an arm that telescopes to a length suitable for the user to position the end of the arm upon which the camera is mounted adjacent his face. A bulbous, generally arcuate-shaped bumper is located at the end of the arm opposite that on which the camera is mounted and permits the use of the camera at various angles relative to the user's torso. Further, a neck strap is pivotally located adjacent the bumper such that when the neck strap is worn about the person's neck, and the camera is in use, the arm of the device is raised to place the camera at the person's eye level and the bumper rests against the person's torso but when the camera is not in use, the arm is lowered to allow the camera to be conveniently carried in front of or to one side of the user.Type: GrantFiled: November 6, 1986Date of Patent: August 18, 1987Assignee: Sima Products CorporationInventor: Steven M.
