Publication number: 20080066599Abstract: A punch for making a decorative design in a sheet medium having a body formed with a fissure for receiving the sheet media, a cutter axially movable within the body and a die secured in the body for engaging with the cutter. The cutter has a first edge for cutting along at least a portion of a periphery of the decorative design, leaving at least another portion of the decorative design uncut. The cutter has at least one second edge within the first edge for cutting a second element within the decorative design, such that the resulting decorative design in the sheet media may be folded upwards from the sheet media along the portion of the decorative design cut by the first edge and where the portion of the design that is folded upward contains the second element cut by the second edge.Type: ApplicationFiled: September 18, 2006Publication date: March 20, 2008Inventors: Ronald Aniceto, Amy Jane Reda

Patent number: 7331266Abstract: A paper punch has a base, two cutters, two articulated linkages and a lever. The base has a top, an open bottom, a cavity, two punch holes and two brackets. The punch holes are defined through the top. The brackets are mounted on the top and each bracket has two guide slots. The cutters are slidably mounted respectively in the brackets and each cutter has a blade. The articulated linkages are pivotally mounted respectively on the brackets and each has a lower link and an upper link. The lower link is mounted pivotally and slidably on a corresponding bracket. The upper link is mounted pivotally on a corresponding lower link. The lever is mounted pivotally on the brackets and is connected pivotally to the upper links of the articulated linkages. The articulated linkages allow a user to press the lever without strenuous effort when punching holes through paper sheets.Type: GrantFiled: November 14, 2005Date of Patent: February 19, 2008Assignee: SDI CorporationInventor: Jau-Shyong Chen

Patent number: 7328642Abstract: A hole-punching assembly comprising a positioning piece, a clamping piece, a plurality of tool holders, two balancing rods and a plurality of hole mountings. Each end of the positioning piece couples to the hole mounting through a balancing rod, the positioning piece has a gliding rail, a receiving slot and a confining part disposed at an indentation at each end for each of the tool holders to go through the positioning piece, thereby fixing the tool holders. Each of the tool holders has a first end extending to one of the hole mountings and a second end being blocked by the clamping piece. The clamping piece has one rod disposed at each end, with each end of the rod protruding through the receiving slot axially and being restrained by the confining part, thereby fixing the clamping piece and forcing the tool holder to move axially to facilitate easy switching and dismantling of the tool holders.Type: GrantFiled: March 31, 2006Date of Patent: February 12, 2008Inventor: Chou-Chih Chiang

Publication number: 20070240814Abstract: There is provided a green sheet through-hole machining apparatus, and a through-hole machining method, that allows deterioration of positional precision of through-holes after perforation to be readily prevented. A releasing plate made of a metallic thin plate is removably set on an upper face of a lower base. Then, a green sheet is interposed between the lower and upper bases and the upper base is pressed by a pressurizing roller to press the green sheet toward the releasing plate. Then, the green sheet is punched by the projections to perforate the through-holes. After that, the green sheet is removed from the lower base together with the releasing plate.Type: ApplicationFiled: April 5, 2007Publication date: October 18, 2007Inventors: Yuji Sakuma, Seiichi Yokoyama

Publication number: 20070227329Abstract: A method of manufacturing an industrial component is provided which can highly accurately form through holes in a target object even with a narrow bar width and a long bar length. The method is for manufacturing an industrial component having through holes with a high aspect ratio by using a punch and a die. The punch has leading ends formed into punching cutters and serving as stacking axes of plural sheets of punch materials. The plural sheets of punch materials are punched by the punch and thereafter kept held by a side surface of the punch. When a given punch material is held by the side surface of the punch, a next punch material is punched and stacked, with the leading ends of the punch projecting farther than the lowest surface of the given punch material.Type: ApplicationFiled: February 20, 2007Publication date: October 4, 2007Applicant: NGK Insulators, Ltd.Inventors: Kazumasa Kitamura, Yoshinori Yamaguchi
