20080309260 | Shaft Type Linear Motor, Mounting Head and Component Mounting Device With the Linear Motor, and Position Detection Method for Shaft for Driving the Linear Motor - A shaft type linear motor including a stator in which plural hollow cylindrical coils are disposed so that the center through holes thereof are arranged linearly so as to form a shaft insertion hole; a driving shaft including permanent magnets, the same magnetic poles, the north or south magnetic poles, being disposed in the axial direction so as to be opposed to each other, and movably inserted into the stator; sensor units disposed in the axial direction of the stator so as to have a predetermined clearance therebetween and equipped with plural magnetic pole detection sensors that detect the magnetic field intensities of the permanent magnets and output magnetic field intensity signals; and a detection section for receiving the magnetic field intensity signals output from the magnetic pole detection sensors and for detecting the position of the driving shaft on the basis of the plural magnetic field intensity signals. | 12-18-2008 |
20090056114 | NOZZLE MECHANISM, MOUNTING HEAD AND ELECTRONIC COMPONENT MOUNTING APPARATUS - In an electronic component mounting apparatus, nozzle mechanisms are formed slender by providing shaft-type linear motors vertically upward of nozzle units and providing linear encoders vertical upward of the shaft-type linear motors, respectively. Thus, it becomes implementable to reduce the occupational area of the individual nozzle mechanisms in XY directions (horizontal direction), allowing the pitch of neighboring nozzles to be narrowed. It also becomes achievable to keep up with increasingly narrowing mounting pitches of electronic components in boards of increasingly smaller-size and higher-integration. | 03-05-2009 |
20090119904 | Method for Detecting Condition of Nozzle Member, Method for Detecting Holding of Components, Method and Apparatus for Mounting Components - An apparatus for mounting components provided with a multi-nozzle type component mounting head for moving vertically includes a plurality of movable parts linearly arranged; a plurality of nozzles respectively connected to tip parts of the movable parts; a height detector for detecting positions of the plurality of movable parts; a light projector provided on an extension of an arrangement of the plurality of nozzles; a light receiver provided at a position opposed to the light projector, wherein all of the plurality of nozzles are made to stand-by on an upper side of an optical axis L from the light projector, an arbitrary one of the nozzles is made to descend, and at a timing when the light receiver detects that light shielding of the light from the light projector is switched by the tip part of the nozzle, a vertical position of the movable part is measured by the height detector. | 05-14-2009 |

20110073603 | SAMPLE LOW-TEMPERATURE STORAGE CASE AND ORGANISM TRANSPORTATION SUPPORTING SYSTEM - The storage case has a structure in which a sample storage case (S) contained in a storage case is cooled and held at a low temperature by a Stirling refrigerator. A detection element is disposed in a room-temperature area of the storage case. The chemical or physical property of the detection element varies when a contaminant adheres to the detection element. Entrance of a contaminant into the storage case can be checked by contactlessly checking the detection element from the outside of the storage case. The storage case includes a server for receiving the result of the check from the detection device, storing the result, and setting up connection via a communication line to at least two out of a terminal operable by the forwarder, a terminal operable by the carrier, and a terminal operable by the recipient to transmit the result to the two. | 03-31-2011 |
