Embodiments of a connector (which may also be also referred to as a connector unit) are described. In accordance with one embodiment, the connector may comprise a case, first and second connectors, at least one stiffener bar, and at least one flexible circuit. The first connector may be located in a first opening of the case and the second connector may be located in a second opening of the case. The stiffener bar may be disposed in the case. The first connector may receive a first end of the flexible circuit while a second end of the flexible circuit may be interposed between the stiffener bar and the second connector.
摘要:
The present invention provides a card connector which prevents the retainer fitting from coming off even when the molded base plate is deformed during reflow soldering and which can be reduced in size, height and weight. The card connector includes a shell body and a molded base plate. The molded base plate includes at least a card eject mechanism incorporating a compression coil spring for inserting/ejecting a card and a retainer fitting for holding the card eject mechanism pushed by the compression coil spring. The shell body is formed with at least one engagement hole for engagement with at least one hook portion of the retainer fitting. The retainer fitting includes a horizontal member and a vertical member rising vertically from the horizontal member. The horizontal member and/or vertical member have at least one pair of press-fit projections and one hook portion.

The present invention provides a card connector whose molded base plate is not deformed during reflow soldering, thus allowing reductions in size, height and weight of the card connector. The card connector of the invention has a shell body and a molded base plate. The molded base plate includes at least a card eject mechanism having a compression coil spring and adapted to insert and eject a card and a stopper for holding the card eject mechanism pushed by the compression coil spring. The shell body includes at least one bent piece for fixing and supporting the stopper in three-dimensional directions.

A damper unit for a piano is provided in which the position of a hammer stop rail for contacting the hammer shanks before the hammers strike the strings can be changed from an inoperative retracted position to a stop position with a relatively small drive force and the hammer stop rail is firmly and reliably positioned at the stop position. Stop rail support arms for supporting the hammer stop rail are connected, via linkage mechanisms composed of links and lever arms, to a rotary shaft. By pulling a wire that is connected to the rotary shaft, the rotary shaft is rotated, such that the hammer stop rail can be positioned, via the linkages, at the stop position and the retracted position, in which the hammer stop rail does not contact the hammer shanks. As compared with the conventional damper unit, the position of the hammer stop rail can be changed with a relatively small drive force. Moreover, the hammer stop rail is thus fixedly positioned at the stop position, thereby reliably dampening the hammer striking sound. The linkage mechanisms may be replaced with a cam mechanism that contacts the stop rail support arms for changing the position of the hammer stop rail.

A porous and spherical silica is recovered in high yields from a neutralized product of an alkali silicate obtained by using an acrylamide type polymer as a coagulation growing agent, and the above silica is reacted as a precursor with a metal compound of the Group II of periodic table in an aqueous medium to obtain amorphous or fine, laminar and crystalline porous and spherical silica or silicate granules having a high degree of true sphericality, a symmetrical grain size distribution and a refractive index over a range of from 1.4 to 1.7. The porous and spherical granules have a primary grain diameter of 0.3 to 30 .mu.m as observed through an electron microscope, have an apparent specific gravity of from 0.05 to 0.5 g/ml, and are cheaply obtained in high yields, and can hence be used as a filler for various paints and resins. In particularly, the granules excellently disperse in the resins, have a refractive index close to those of the resins, are not crushed during the kneading with resins or extrusion, or do not damage the apparatus. The films obtained by using these granules exhibit very excellent transparency, anti-blocking property and scar resistance. Moreover, the porous and spherical zinc phyllosilicate type granules having fine grain sizes and symmetrical grain size distributions, are excellent in their odor scavenging property and sweat controlling property.

The amorphous silica has a large apparent specific gravity despite of its BET specific surface area of 20 to 500 m.sup.2 /g, has an oil absorption amount of as small as 50 to 120 ml/100 g, has an agglomeration degree (D1/D0=DA) defined by the ratio of silica elementary particle diameter D0 to primary particle diameter D1 of from 10 to 50, and has nearly a spherical particulate structure which is quite different from that of the conventional gelation method silica (DA=.infin.). The amorphous silica-type filler exhibits excellent properties in regard to handling, processability, dispersion property and abrasion-resistant property and, when added as, for example, an anti-blocking agent, makes it possible to obtain resin films having transparency and scratch-resistant property without fisheyes or voids. Owing to the above properties, the amorphous silica that is used as a filler for the heat-sensitive recording papers suppresses ground fogging, improves the image concentration, makes it possible to apply a highly viscous coating solution since the filler dispersed in an aqueous solution creates very small viscosity, and imparts excellent abrasion resistance to the apparatus during the step of coating.

Disclosed is a composite adsorbent consisting of a molded body of a homogeneous mixture comprising powdery active carbon and hydrous alumina of the pseudoboehmite type. This composite adsorbent has high mechanical strength and abrasion resistance. This composite adsorbent is excellent in the capacity of adsorbing organic components such as gasoline, and the desorption of the adsorbed components can be easily accomplished at a high desorption ratio. These excellent capacities are retained even if the adsorption-desorption cycle is repeated. Accordingly, this composite adsorbent is especially valuable as the adsorbent for an automobile canister.

An inorganic filler composed of a modified montmorillonite group clay mineral and having an X-ray diffraction pattern inherent to montmorillonite, an oil absorption of at least 100 ml/100 g and a Hunter whiteness of at least 80%. The modified clay mineral is produced by reacting a clay mineral of the montmorillonite group which 10 to 200% by weight based on the dry weight of the mineral, of an alkaline earth metal hydroxide in the presence of water, and reacting the reaction product with a salt of a metal of Group IIb, III or IV of the periodic table containing an acid radical which gives a soluble alkaline earth metal salt upon reaction. The inorganic filler is especially suitable for use in lightweight paper.

A card connector has a housing, a sliding member that is designed to receive a card, and a latching member that is connected to the housing. The sliding member is slidable relative to the housing. The latching member is designed to engage the card to prevent the card from being removed from the housing.
