  • Patent number: 7123487
    Abstract: In a structure where the lid portion is mounted on the main housing body comprising apertures and in such a manner as to turn freely thereon, the concave lock portion and the locking protrusion adjacent thereto capable of locking the lid in the closed state are located in the aperture side of the main housing body. The lid portion is provided with the hooking piece comprising the spring portion and the arc-shaped protrusion. When the lid portion turns to open or close the aperture portion, the arc-shaped protrusion comes into contact with the locking protrusion under pressure with the spring portion, in order that a force opposing to the turning direction may be applied thereto before and after it passes through the locking protrusion, to keep the lid portion in two states i.e. the open state and the closed state.

  • Patent number: 7118638
    Abstract: An organic electroluminescence display includes a transparent glass substrate, an ITO anode layer, a positive hole transition layer, an RGB luminescence layer, an electron transition layer and a metallic cathode layer. Highly pressurized N2 gas is sealed in the interior of the display. To absorb and retain the moisture in the sealed gas, a hygroscopic member is disposed between a sealing member and the cathode layer. The hygroscopic member includes a nonwoven fabric including a fiber layer made of fibers bonding to each other and a hygroscopic agent adhering to one surface of the fiber layer and an air-permeable sheet covering the nonwoven fabric as a whole.

  • Patent number: 7108557
    Abstract: An Integrated Circuit (IC) card connector includes a housing member, an ejection mechanism, and a plurality of braking pieces. The housing member includes an accommodation portion for selectively accommodating an IC card. When the ejection mechanism ejects the IC card from the accommodation portion, an end of at least one of the plurality of braking pieces contacts a movable part of the ejection mechanism. After contacting the movable part of the ejection mechanism, the end of the at least one braking piece retreats. Thus, the braking piece decelerates the ejection speed of the IC card and avoids the undesirable jumping-out of the IC card. Embodiments consistent with the invention may also include an improper insertion piece provided in the housing member.

  • Patent number: 6976863
    Abstract: A guide member is supported to be movable relative to an accommodation portion of a contact-moving member An engagement pin is engaged with a post portion so that the maximum displacement of the guide member is limited within the maximum displacement of a semiconductor element. The inner circumference of the accommodation portion of the contact-moving member is brought into contact with the outer circumference of the guide member so that the maximum displacement A of the contact-moving member is limited. Thus, a gap CL (=A?B) is defined between the inner circumference of the contact-moving member and an end surface of the guide member opposed thereto.
