A connector for a jack includes four contacts of first, second, third and fourth contacts each having a contact portion and a connection portion, and a housing, to exchange signals and to ascertain whether a plug connector has been inserted into the connector. The third contact substantially U-shaped in cross-section includes a contact piece having a first contact part adapted to contact the plug connector, and a spring piece having an elasticity facing to the contact piece and provided by forming a U-shaped slit in a part of the third contact at a location opposite to the contact piece. When the plug connector is inserted into the connector, the plug connector pushes the first contact part of the contact piece to cause the contact piece to be displaced to the spring piece so that the contact piece pushes the spring piece to cause the spring piece to be displaced toward the housing and at the same time the spring piece pushes the contact piece with each other with the aid of its elasticity. The connector achieves a reliable holding force for the plug connector without scratching it.

A card connector includes contacts adapted to contact contacts of two memory cards, a housing having inserting openings for inserting the memory cards and arranging and holding the contacts therein, and a shell covering the housing. The housing includes two side walls, a rear wall, and a lower wall contiguous with these side and rear walls to form the inserting openings for the memory cards by these two side walls, rear wall and lower wall, and is provided with a pivotally movable plate to form, by its pivotal movement, the one inserting opening for inserting either of the cards and simultaneously to prevent the other card from being inserted. The card connector enables stable connection by merely inserting two different cards having equal lengths in the inserting direction and different widths and thicknesses into the connector.

A blower includes: an impeller on which there are arranged axial flow blades 40 mounted at circumferential intervals to an outer peripheral surface of a boss; a case surrounding the impeller; and a bell mouth cylindrically constricted to guide gas into the case, wherein an inner diameter of the bell mouth is smaller than an outer diameter of the impeller. Further, each blade has, in the radial direction, a sweepforward wing portion situated on the boss side and exhibiting a positive advance ratio value, and a sweepback wing portion situated on the outer peripheral side of the blade and exhibiting a negative advance ratio value, with the arc length of each blade increasing from the boss side toward the outer peripheral side. Therefore, it is possible to achieve an improvement in ventilation efficiently, through an increase in static pressure and to achieve a reduction in noise.

An electrical connector adapted to be mounted onto a panel of an electronic appliance includes a housing and a predetermined number of contacts held and fixed in the housing. The housing includes one or more projections formed on each of an upper surface and a lower surface of the housing, and the projections are adapted to be positioned on a first side of the panel. The electrical connector also includes a block which engages the housing, and the block is adapted to be positioned on a second side of the panel which is opposite the first side of the panel. Moreover, the block includes a through-hole formed therethrough. The electrical connector also includes a fixing pin, and a portion of the fixing pin is positioned within the through-hole.

The present invention relates to a method of removing harmful components selected from the group consisting of volatile inorganic hydrides, volatile inorganic halides and organometallic compounds and a method of detecting the same, apparatus employed according to these methods. The harmful components can be removed by bringing it into contact with a crystalline cupric hydroxide. The harmful components can be detected based on the color change of the copper hydroxide.

A plurality of curved rectangular blades are arranged in a circumferential direction on a periphery of a disc, forming a pipe-like basket shape with an opening on a front side of the disc. Rotation of the disc draws in air from the opening and draws out the air in a centrifugal direction through a space between the blades. The blades are formed of a thick plate part close to the disc and a thin plate part that is thinner than the thick plate part and farther than the thick plate part from the disc. A bulge serving as a boundary between the thick plate part and the thin plate part is formed on a negative pressure surface of the blades, which is of curved convex shape.

A card connector includes a plurality of contacts adapted to contact memory cards, a housing holding the contacts and having a plurality of inserting openings arranged in vertically overlapping relationship for inserting memory cards, respectively, and a shell covering the housing. A pivot member is installed at a predetermined position in the housing so as to be pivotally moved when one memory card is inserted in one of the inserting openings such that part of the pivot member extends into all the inserting openings except for the one inserting opening, thereby preventing a further memory card from being inserted into the card connector. In assembling, after the pivot member is set in the housing so that protrusions provided in the housing are fitted in slits formed in the pivot member, the shell is fitted on the housing to push the pivoting member into the predetermined position.
