20090028713 | Centrifugal multiblade fan - 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. | 01-29-2009 |
20090053922 | Connector for jack - 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. | 02-26-2009 |
20090263240 | MULTIBLADE CENTRIFUGAL BLOWER - A multiblade centrifugal blower in which a length from a rear end to a front end of an outer edge of a blade is shorter than a length from a rear end to a front end of an inner edge of the blade. Moreover, a bell mouth is located at an air inlet such that a distance from a tip part of an inner edge of the blade to an inner wall of a scroll casing is minimum at an inner tip part of the bell mouth. | 10-22-2009 |
20100190365 | Card connector - A card connector for a plurality of memory cards includes a housing having a plurality of inserting holes for the memory cards, respectively. The card connector includes a swing member made of an elastic metal plate and having fixing portions and a swing part in the form of a hollow square rod having extending portions extending into the inserting holes when the swing member is fixed in the housing. A partition wall between the inserting holes is formed with a rectangular notch and slits in opposite faces of the rectangular notch for press-fitting the fixing portions of the swing member, respectively. When one memory card is inserted into one inserting hole, the inserted memory card causes the swing part to be further extended into anther inserting hole, thereby preventing another memory card from being inserted into the another inserting hole. | 07-29-2010 |
20120009059 | MULTIBLADE FAN - To provide a multiblade fan that enables an improvement in noise characteristics or blowing performance. The multiblade fan includes a scroll type casing that has a bell-mouthed inlet and an impeller housed in the casing. The impeller includes a plurality of blades and a rotation axis m oriented toward the inlet of the casing. The blades are annularly arranged. In the multiblade fan, a center axis of the inlet and the rotation axis of the impeller are arranged at a tilt angle to each other and in any one of an intersecting positional relationship and a skew-lines positional relationship so that a space between the inlet and the impeller increases from the rotation axis of the impeller toward an outlet of the casing. | 01-12-2012 |
20120017459 | HAND DRYER - A hand dryer includes a hand drying chamber that includes a hand insertion opening from which a hand is inserted, a first wall section that faces the hand inserted from the hand insertion, opening, a second wall section that faces the hand and the first wall section, and a plurality of air nozzle sections, which extends in a direction from the hand insertion opening to a far side and jets a high-speed air, on any one of the first wall section and the second wall section, wherein a distance between the first wall section or the second wall section that faces the air nozzle sections and the air nozzle sections is large in an upper portion and is small in a lower portion. | 01-26-2012 |
20120017460 | HAND DRYER - A hand dryer includes a hand drying chamber that includes a hand insertion opening from which a hand is inserted, a first wall section that faces the hand inserted from the hand insertion opening, a second wall section that faces the hand and the first wall section, and a plurality of air nozzle sections, which extends in a direction from the hand insertion opening to a far side and jets a high-speed air, on any one of the first wall section and the second wall section, and a distance between the air nozzle sections in a horizontal direction is wide on a side of the hand insertion opening and is narrow on the far side. | 01-26-2012 |
20150300675 | AIR-CONDITIONING APPARATUS - An air-conditioning apparatus includes refrigerant systems that each include an outdoor unit and indoor units and that air-condition a single room, and circulators for making a temperature distribution in the room uniform. The air-conditioning apparatus determines a load on each of the two refrigerant systems in operation, and, if it is determined that improvement of operating efficiency is possible on the basis of the determination result, performs a system-selective operation in which operation of one of the refrigerant systems determined to be under a low load is stopped and the other refrigerant system determined to be under a high load is selectively performed, and causes the circulators to transport blown air blown from the indoor units of the refrigerant system determined to be under a high load to an air-conditioned zone of the refrigerant system determined to be under a low load. | 10-22-2015 |
