  • Patent number: 6415658
    Abstract: The present invention is directed to a wear detection probe in which the deflection of a folded portion of an electric detection wire is suppressed so as to be able to cut the folded portion of the wire in a secure position. A truncated cone is formed at the edge part of a retention member, and a groove extending in a diametric direction is cut at the edge part. A supporting protrusion is formed by traversing the groove, and the electric detection wire is retained in a position in which the folded portion is securely mounted on the supporting protrusion which extends from both openings from which the electric wire extends. The wire is sandwiched by both side walls of the groove and the side walls operate as regulating walls so that when the folded portion of the electric wire begins to be exposed and contacts a brake drum, the folded portion will not be pulled out by a deflecting force in a sidewards direction.

  • Patent number: 6319077
    Abstract: A cable connector combination wherein the cable has an electrically conductive core and an extra-thick insulating sheath. There is a terminal fitting which includes a wire barrel and an insulator barrel. The former grips the exposed length of bare wire core and the latter grips a reduced diameter portion of the sheath. The exposed length is formed by stripping the insulation completely from one end, and the reduced diameter portion of the sheath is formed by stripping part of the insulation from the cable, preferably at a point adjacent the exposed length. The reduced diameter is the same as the outer diameter of a normal sized cable and, therefore, will fit easily and readily into the standard insulator barrel. Thus, no special fittings are required, and the abrasion-resistant cables can be handled along with all of the others. An apparatus for carrying out the method is also disclosed.

  • Patent number: 6141872
    Abstract: A method of producing products wherein semi-finished products are supported between a pair of elongate, parallel carriers. Each semi-finished product is shaped by pressing the product into a finished form. Also, each semi-finished product is connected to at least one of the carriers by a deformable element. Deformation of the deformable element allows the semi-finished product to approach or move away from that carrier. Thus, when the semi-finished product is shaped by pressing, deformation of the deformable element allows the semi-finished product to move relative to that carrier so that unwanted tensions are relieved. Accordingly, the semi-finished product does not twist undesirably.

  • Patent number: 5715257
    Abstract: An SR (Selective Repeat) ARQ system with limited buffer memory is realized by modifying a part of a user data area. A transmitter side modifies a part of a user data area in a data frame so that it differs at least one bit from corresponding part of a frame with the same frame number as that of a current frame in a preceding modulo turn, and a receiver side compares said part of a user data area with corresponding part of a frame with the same frame number as that of a current frame in a preceding modulo turn. When they coincide, the receiver side disregards the received frame as it is re-transmitted frame which is already received correctly, and when they do not coincide, the receiver side takes the received frame. Preferably, said part of a user data area is the last word area in a user data area in a frame structure.

  • Patent number: 5608376
    Abstract: A brake pad wear probe contains a plurality of terminals turned or bent into a U-shape with their tip positions offset from each other. The terminals are cut in stages according to the wear development degree of the brake pad. The terminals define energization routes to electro-magnetic coils at relays, and the broken line state of the terminal can be detected at the respective relay by detection of a break in its corresponding energization route. As a result, electro-magnetic switches work in response to the wear development degree, turning on predetermined indicator lamps of a display to inform a driver of the brake wear condition.

  • Patent number: 4993046
    Abstract: In Trellis coded modulation system in which an input digital signal in parallel form is encoded by a convolutional encoder which adds an additional bit to the input digital signal for error correction purpose, and a mapping circuit designated amplitude and phase for each symbol for QAM signal, the number of parallel bits at output of said convolutional encoder is the same as the number of parallel bits of an input digital signal. An input digital signal is first rate converted so that m+n bits in every T period is converted to m bits in every T' period, where T'=(m/(m+n)).T. The convolutional encoder adds n number of bits so that the total number of parallel bits is m+n, which is applied to the mapping circuit. In a receive side, a received signal having m+n bits in every T' period is decoded through an error correction decoder which provides m bits in every T' period, then, the decoded signal is rate converted to m+n bits in every T period.
