Abstract: A butterfly-type control valve (1) includes a valve housing (2) that is molded from synthetic resin. The valve housing has a housing wall that defines a flow path (3). A non-circular valve member (5) is disposed within the flow path and has opposing long sides (5a). The valve member (5) is mounted on a valve shaft (4) that is rotatably supported by the valve housing. The housing wall has wall portions (2a) that extend substantially parallel to the long sides (5a) of the valve member. Each of the wall portions (2a) has an inner surface (2a1) that is concave in a direction away from the valve shaft in a state after the valve housing has been molded and before the valve housing has been cooled.

Abstract: A wire collecting device includes at least two independent main wheel bodies provided with a side recesses at side walls thereof, respectively, large turning wheels having a larger diameter, respectively, and small turning wheels having a smaller diameter, respectively, wherein each pair of large and small turning wheels have a same center opening, respectively; large and small wire storage grooves formed at wheel breadths of the large and small turning wheels; and independent immovable axes flexibly connected into the center openings of the main wheel bodies, respectively. According to the aforesaid structure, a wire is winded and stored in the large and small wire storage wheels, respectively, and are distinguished as at least two A and B wires and at least two C and D wires being stored in the large and small wire storage grooves, thereby selectively and independently releasing at least two wires with predetermined lengths.

Abstract: An ice rink defines a predetermined shape and includes a source of black and/or white light for illuminating the surface of the rink. In one form, the rink includes a plurality of rectangular synthetic panels and a plurality of adjusting elements for forcing the panels tightly together and for compensating for changes in temperature. The panels also include a plurality of grooves and a plurality of metal splines which are dimensioned to fit into the grooves of adjacent panels to provide a smooth skating surface.

Abstract: A pair of pliers has a handle (11), a head (13), a rivet (15), at least one colored layer (17) and optionally, plastic sleeves on the handle (11). The at least one colored layer (17) is at least one color especially designed with unique features to make identification of the pliers easy and make the pliers have an attractive appearance.

Abstract: The present invention relates to a memory card connector comprising an insulation base seat, a shielding shell, a plurality of conductive terminals, a detecting means, a writing-protection detecting, and a card advancing/withdrawing mechanism. The card advancing/withdrawing mechanism has an integral connecting arm, and therefore made simple constituent parts and low manufacturing cost. The present invention is applicable to memory card automatic locating and withdrawing.

Abstract: The LEDs of a display panel are arranged in a matrix array and oriented at an angle with the directions of columns or rows. Such an orientation causes the diffused light incident on neighboring LEDs of activated LEDs to create a shaded area with the same aspect ratio of the activated pattern and to yield a virtual stereoscope illusion.

Abstract: A battery charger having an attached base includes a battery charger main body having a power plug and a connected wire with a predetermined length; and a base consisted of left and right housings and provided with upper and lower guiding orifices such that the wire enters the base via the upper guiding orifice and an outer end of the wire connected to a plug is extended out of the base via the lower guiding orifice. Wherein, the base is provided with a storage recess at an inner surface thereof, an inner surface of the main body may be superposed onto the inner surface of the base, and the power plug is placed and concealed in the storage recess.
