  • Patent number: 7438598
    Abstract: The connector housing 30 is formed with a pair of guide grooves 50a, 50b and a pair of side walls 60. The guide grooves 50a, 50b support the both side edges of the upper body portion 21 of the thick first card 20 and also the both side edges of the card body 11 of the thin second card 10 and guide these cards as they are inserted or extracted. The side walls 60 define, below a space between the paired guide grooves 50a, 50b, a space in which to accommodate the lower body portion 23 of the first card 20. This construction ensures that, whichever of the first and second cards is inserted, the elastic displacements of the contact terminals 40 of a card connector 1 remain the same, allowing the card to be electrically connected stably.

  • Publication number: 20080011017
    Abstract: A method for fabricating a glass substrate for an information recording medium ensures removal of an abrasive or foreign mater adhered to the glass substrate after a polishing step, and involves, after the polishing step, keeping the surface of the glass substrate in contact with a liquid for 10 minutes or more before a scrub-cleaning step. To ensure that the abrasive or foreign matter firmly adhered to the glass substrate is removed by scrub-cleaning, preferably, the surface of the glass substrate is kept in contact with the liquid with the glass substrate immersed in the liquid which is collected.
