20080229010 | STORAGE SYSTEM AND METHOD FOR CONTROLLING CACHE RESIDENCY SETTING IN THE STORAGE SYSTEM - In a storage system adopting an external storage connection configuration, a first storage apparatus is capable of integrally managing the cache residency settings made in second storage apparatuses, which serve as external storage apparatuses. The first storage apparatus stores the cache residency information for the second storage apparatuses, i.e., external storage apparatuses, in a shared memory thereof. When the storage system receives a cache residency setting request from a management device or the like, the first storage apparatus issues a cache residency setting instruction to a second storage apparatus with reference to the residency information. In accordance with the setting instruction, the second storage apparatus sets a cache-resident area in a cache memory thereof. | 09-18-2008 |

20080317575 | COMPONENT TRANSFERRING APPARATUS AND IC HANDLER - A component transferring apparatus includes a shuttle; an inspection socket; a retaining device that moves between the shuttle and the inspection socket; a pressing device included in the retaining device to hold and transfer an electronic component; a position adjusting device that moves the pressing device to correct a position of the electronic component based on an image processing of image data obtained by photographing of the electronic component; a socket mark provided near the inspection socket; a hand mark provided on the retaining device such that the hand mark is positioned near the socket mark when the retaining device is moved to a mounting position where the electronic component hold by the pressing device is mounted in the inspection socket; a first camera provided on the shuttle to photograph a single image including the electronic component hold by the pressing device and the hand mark provided on the retaining device; a second camera that photographs a single image including the socket mark and the inspection socket and a single image including the socket mark and the hand mark of the retaining device moved to the mounting position; a first relative-position calculating unit that performs an image processing of data obtained by photographing of the single image including the socket mark and the inspection socket to obtain a first relative position between the socket mark and the inspection socket; a second relative-position calculating unit that performs an image processing of data obtained by photographing of the single image including the socket mark and the hand mark located at the mounting position to obtain a second relative position between the socket mark and the hand mark; and a third relative-position calculating unit that performs an image processing of data obtained by photographing of the single image including the electronic component and the hand mark to obtain a third relative position between the hand mark and the electronic component, wherein based on the first, the second, and the third relative positions, the position adjusting device corrects the position of the electronic component to mount the electronic component in the inspection socket. | 12-25-2008 |
20120034052 | COMPONENT TRANSFERRING APPARATUS AND IC HANDLER - An apparatus includes: a retainer moving between a shuttle and a socket; a presser holding a component; an adjuster moving the presser; a socket mark near the socket; a hand mark near the socket mark when the retainer is at a component mounting position; a first camera photographing a first image including the component and hand mark; a second camera photographing a second image including the socket mark and socket, and a third image including the socket mark and hand mark; a first calculator obtaining a first relative position between the socket mark and socket from the second image; a second calculator obtaining a second relative position between the socket mark and hand mark from the third image; and a third calculator obtaining a third relative position between the hand mark and component from the first image. The adjuster corrects the component's position based on the relative positions. | 02-09-2012 |
20130205804 | HANDLER AND PART INSPECTING APPARATUS - A handler includes a storage tank which stores liquid nitrogen, supply channels which supply refrigerant from the storage tank to inner passages of a first shuttle, a valve which opens and closes the supply channel, and a heat exchanger which has vaporization chambers with larger flow path cross-sectional areas than those of the supply channels to vaporize liquid nitrogen within the vaporization chambers. According to this structure, the respective vaporization chambers are filled with nitrogen gas produced by preceding vaporization. Thus, pressure fluctuations produced by successive vaporization of liquid nitrogen can be reduced. Moreover, nitrogen gas is supplied to the respective inner passages. Accordingly, excessive cooling for part housing pockets can be prevented. | 08-15-2013 |
