Granted: 2007-12-18
Abstract: The invention provides a jack type connector B with a thin shutter which is to be used in, for example, an IO port of a mobile terminal device such as a portable telephone, and also a plug type connector A which is to be used in combination with the jack type connector with a shutter. In the jack type connector B with a shutter, a shutter 5 which is molded by an electrically conductive resin material is accommodated in a housing 1 in an openable and closable manner, and the shutter 5 is always urged toward the closing position by a spring member 55. When the shutter 5 is at the closing position, a butting portion 52a of the shutter 5 is in contact with a grounding contact piece 41 incorporated in the housing 1. A protrusion 54 is disposed on the lower end of the shutter 5, whereby a sufficiently large insulation space is en-sured between the shutter 5 and terminals 3. The plug type connector A has terminals 73 and protrusion portions 8 which are projected in front of the terminals 73. The protrusion portions 8 are useful for pushing open the shutter 5. When the plug type connector A is pried and tilted, the protrusion portions 8 escape to the outside without changing the initial shape of the jack type connector B.

Abstract: L'invention concerne un système localisateur d'étiquette à résolutions multiples qui divise une image d'entrée en de nombreuses cellules à pixels multiples. Le système localisateur d'étiquette à résolutions multiples crée alors une image décimée ou une image de faible résolution correspondant à l'image d'entrée. L'image décimée comprend une valeur de caractéristique commune qui correspond à une cellule à pixels multiples de l'image d'entrée. Le système localisateur d'étiquette à résolutions multiples identifie une ou plusieurs zones dans l'image décimée qui possèdent des caractéristiques correspondant aux caractéristiques recherchées. Tout en produisant l'image décimée, le système localisateur crée simultanément une image à apparition de bordure correspondant à l'image d'entée. L'image à apparition de bordure comprend une valeur de bordure correspondant à chaque cellule de l'image d'entrée. Chaque valeur de bordure représente le nombre d'apparitions d'une bordure dans les pixels d'une cellule correspondante de l'image d'entrée. Le système localisateur identifie une ou plusieurs zones candidates dans l'image d'entrée qui présentent des caractéristiques d'image décimée et des caractéristiques d'image à apparition de bordure qui correspondent aux caractéristiques recherchées. Le système localisateur permet alors de classer les zones candidates selon la probabilité que l'image d'entrée contienne des indices de caractéristiques recherchées. Enfin, le système localisateur établit une liste d'une ou plusieurs zones candidates qui contiennent, le plus probablement, des indices de caractéristiques recherchées.

Abstract: The present invention provides a manhole cover/frame exchange method capable of minimizing the size of a portion to be mended, of eliminating a pressing step by a roller machine, of eliminating/reducing steps and a required mending time and of suppressing vibrations, noises and the like during the exchanging process. The manhole cover/frame exchange method comprises steps of: cutting a portion of a paved road around the manhole cover/frame spherically; removing the spherically cut portion; filling a self-curing highly fluid non-shrink filler into a spherical hollow space formed by the removing step, and filling a surface layer material over the self curing highly fluid non-shrink filler. Thus, the pressing step by the roller machine is eliminated by the present invention.

Abstract: An adjustable resilient blade support for use in the forming section of a papermaking machine. The blade support is adjustable, both to allow the attached blade to be moved from a position where it is out of contact to a position where it is pressed into contact with the adjacent forming fabric, and to permit adjustment of the blade orientation relative to the surface of the forming fabric. The blade support is also resilient, and thus allows the blade to respond to transient localised changes in the path of the forming fabric with which it is in contact. The adjustable resilient blade support o f this invention is thus of use in an open surface forming section, and also i s of use in forming sections in which two forming fabrics are used.
