  • Publication number: 20130080604
    Abstract: The present invention is for efficiently managing large numbers of apparatuses using multiple management protocols. A management information acquisition part 1A uses multiple different management protocols P1 and P2 to acquire management information for each of the management protocols from each apparatus 3. Anode configuration information management part 1B identifies apparatus configuration information acquired from the same apparatus of the respective apparatuses 3 by comparing the apparatus configuration information, and collectively manages these multiple pieces of apparatus configuration information as a single piece of apparatus configuration information. A component information management part 1C identifies multiple pieces of component information related to the same component, and manages these identified multiple pieces of component information after associating these pieces information with each other.

  • Patent number: 8393543
    Abstract: An optical aberration is intentionally introduced into the optical system which produces the scanning beam of an optical code scanner, in order to produce a scanning beam which has plural focal points or waists at different distances from the scanner. The operating range of the scanner can thereby be increased by taking advantage of different beam waist locations when the optical code is at different distances from the scanner. In accordance with an embodiment of the invention, coma is intentionally introduced to an optical system providing a light beam for an optical code scanner. This provides a scanning beam with plural beam waists at different distances from the scanner. This may be accomplished by orienting the light source and focusing optical system so that their optical axes intersect or by introducing an optical member, such as a prism, between the original light source and the focusing optical system.

  • Patent number: 8387559
    Abstract: Fluorine gas generators are connected with semiconductor manufacturing apparatuses through a gas supplying system including a storage tank that can store a predetermined quantity of fluorine gas generated in the on-site fluorine gas generators. When one or more of the on-site fluorine gas generators are stopped, fluorine gas is supplied to the semiconductor manufacturing apparatuses from the storage tank storing a predetermined quantity of fluorine gas, so as to keep the operations of the semiconductor manufacturing apparatuses. Thereby obtained is a semiconductor manufacturing plant in which fluorine gas generated in the fluorine gas generators can be safely and stably supplied to the semiconductor manufacturing apparatuses, and with superior cost performance.

  • Patent number: 8366886
    Abstract: A fluorine/fluoride gas generator which has an electrolyte made of mixed molten salt containing hydrogen fluoride in an electrolytic cell including an anode chamber and a cathode chamber, and generates a gas containing fluorine by electrolyzing the electrolyte, includes a raw material supply pipe for supplying an electrolysis raw material, reaching the inside of the electrolyte in the electrolytic cell, a normally-closed valve provided in the middle of the raw material supply pipe, and a bypass pipe provided with a normally-open valve, joining the raw material supply pipe on the downstream side from the normally-closed valve to a gas phase area of the electrolytic cell. Accordingly, the electrolyte is prevented from being suctioned into the raw material supply pipe in the fluorine/fluoride gas generator, and solidification of the electrolyte inside the raw material supply pipe can be prevented.

  • Patent number: 8012258
    Abstract: The liquid surface position of the melt in the crucible in the silicon single crystal growth process utilizing the Czochralski method is monitored using the melt surface position on the occasion of seeding as a reference position and an estimated melt surface position can be calculated according to every situation, so that the distance between the melt and the thermal shield or water-cooling structure can be controlled with high precision. When the estimated melt surface position passes a preset upper limit and approaches the thermal shield, an alarm goes off and, further, when the melt comes into contact with the thermal shield or approaches the water-cooling structure, an alarm goes off if desired and, at the same time, the crucible is forcedly stopped from moving, so that a serious accident such as steam-incurred explosion resulting from the melt coming into contact with the water-cooling structure can be prevented.

  • Publication number: 20100181378
    Abstract: A compact barcode reader is provided in which the imaging lens and a linear sensor are in a straight line path with the barcode (no bend in path). By using a wide angle lens with a short back focus, it is possible to reduce the distance between the barcode and linear sensor to a fraction of what it was in the prior art. In addition, the maximum image height and the downward projection of the sensor are reduced to a fraction of what they were in the prior art. As a result, despite the straight line optical path, compact barcode reader becomes so small that it does not interfere with the operation of the beverage maker.
