  • Patent number: 9453509
    Abstract: A scroll compressor which can be mounted in an automobile has a slide bearing resulting from baking onto a back metal a sliding layer of 5-60 wt % graphite having an average diameter of 5-50 ?m and a graphitization degree of at least 0.6, the remainder containing a polyimide resin and/or a polyamide-imide resin. The form of the graphite has: (a) an average shape factor (YAVE) as defined of 1-4 for the particles excluding the minute particles that are no greater than 0.5 times the average diameter, and there being at least 70% by number of particles having a shape factor (Y) in the range of 1-1.5; or (b) graphite particles having a particle ratio of at least 0.5 being at least 50% of the total by number.

  • Publication number: 20140301880
    Abstract: [Problem] To exchange the roller bearing that has been used in a scroll compressor mounted in an automobile with a m slide bearing. To provide a slide bearing having a performance that is at least equivalent to that of a roller bearing. [Solution] The slide bearing results from baking onto a back metal a sliding layer of 5-60 wt % graphite having an average diameter of 5-50 ?m and a graphitization degree of at least 0.6, the remainder comprising a polyimide resin and/or a polyamide-imide resin. The form of the graphite has: (a) an average shape factor (YAVE) as defined of 1-4 for the particles excluding the minute particles that are no greater than 0.5 times the average diameter, and there being at least 70% by number of particles having a shape factor (Y) in the range of 1-1.5; or (b) graphite particles having a particle ratio of at least 0.5 being at least 50% of the total by number.

  • Patent number: 7788318
    Abstract: A user sends a printing request of a cost estimate to an electronic file management server, applying a user terminal. The electronic file management server that received the printing request, generates printing data of the cost estimate. Next, the electronic file management server allots URL to the generated printing data, and stores the printing data, and URL in a document data storing unit. Then, the electronic file management server generates a two-dimension bar code including the URL, allotted to the printing data, and the data concerning the printing condition, and sends it to the user terminal. Then, a printing apparatus obtains via a bar code reader, the read data of the two-dimension bar code output to a display unit, obtains printing data from the electronic file management server, applying the URL extracted from the two-dimension bar code, and performs printing.
