Patent number: 7423506Abstract: An annular magnet is formed by coupling a plurality of arc-shaped divided magnets with each other in an annular shape as well as such being magnetized with N and S magnetic poles on the end surfaces thereof in an axial direction, wherein the annular magnet is formed such that each of the divided magnets has joint portions at both ends thereof so that the divided magnets are joined to each other. Each of the joint portions also has a joint surface to overlap the joint portions of adjacent divided magnets in the axial direction. The joint surface is magnetized to a magnetic pole different from that of a joint surface to which such is joined, and the divided magnets are coupled with each other by the magnetic attraction force of different magnet poles.Type: GrantFiled: July 7, 2006Date of Patent: September 9, 2008Assignee: SMC CorporationInventor: Atsushi Terasaki

Publication number: 20080150662Abstract: This invention is about a magnetic restraining system. Keeping non electronics or electronics devices such as keyboards and mice stabilized on moving or non moving carts can be very difficult. This invention solves this problem by using a magnet that can be embedded inside the device or glued at the bottom of the device to prevent the device from sliding or falling from any metallic surface that can be attracted by a magnet. The metallic surface can be with or with out coating or covering.Type: ApplicationFiled: December 22, 2006Publication date: June 26, 2008Inventor: Clifton Broumand

Patent number: 7389870Abstract: An instrument caddy and protection device is disclosed having a retentive pocket configured to closely adapted to, retain against displacement and protect an electronic instrument therein such as, for example, a multi-meter. The instrument caddy includes at least one magnet that enables the caddy to hold an instrument against a metallic surface during use while simultaneously protecting the instrument against breakage. Alternate embodiments of the caddy are disclosed wherein the retentive pocket is initially filled with sectioned and removable foam insert material enabling custom sizing of the retentive pocket so as to adapt to an instrument having given dimensions. In addition, preferred embodiments of the caddy provide for passageways for test cables and/or instrument straps to be attached to the instrument while it is held with the retentive pocket.Type: GrantFiled: December 5, 2005Date of Patent: June 24, 2008Inventor: Robert Slappay
