Abstract: Provided is a semiconductor memory device comprising an active region extending in a cell isolation layer, wherein the active region includes a first region and a second region; a bit line intersects the active region; a bit line contact between a substrate and the bit line, wherein the bit line contact is electrically connected to the first region; a bit line spacer that is on side surfaces of the bit line and the bit line contact; a node pad on a lateral side of the bit line spacer, wherein the node pad is electrically connected to the second region; a storage contact that is on the node pad and on a side surface of the bit line spacer, wherein the storage contact includes a first part having a first width and a second part having a second width different from the first width.

Abstract: A wind control blade (31) of a wind guide (30) of the present invention forms a 20° wind control blade lateral curved surface gradient angle (32), a 30° wind control blade longitudinal spiral twist angle (33), a 180° wing control blade alignment angle (34), and a 15° wind control blade rear gradient angle (35). In addition, a turbine blade (41) forms a 30° turbine blade lateral curved surface gradient angle (42), a 40° turbine blade longitudinal spiral twist angle (43), and a 120° turbine blade alignment angle (44). The 20° wind control blade lateral curved surface gradient angle (32) and the 30° wind control blade longitudinal spiral twist angle (33) of the wind control blade (31) have more gradual and wider incidence angles than the 30° turbine blade lateral curved surface gradient angle (42) and the 40° turbine blade longitudinal spiral twist angle (43) of the turbine blade (41).

Abstract: Disclosed is a generator wherein a rotary shaft is rotatably supported by a rotary shaft rest, and an inner casing is formed in a cylindrical hollow shape in such a way that one side thereof is fixedly engaged to the rotary shaft, thus rotating by the rotary shaft, and another side thereof is engaged to a rotary shaft rest by an inner casing engaging support member which includes a thrust bearing, and a plurality of through holes and ventilation holes are formed at the side surfaces and outer circumferential surfaces of the inner casing and the outer casing.
