  • Publication number: 20090205154
    Abstract: A side plate of an impeller is formed so that the height thereof is lowered gradually from an edge portion of a central opening portion toward a circumferential portion. When the distance from the edge portion of the central opening portion to the circumferential portion, in a direction perpendicular to the output shaft, is taken as L, the distance from the edge portion of the central opening portion to the circumferential portion, in the direction of the output shaft, is taken as H, a point on the side plate away from the edge portion of the central opening portion by 0.1×L in the direction perpendicular to the output shaft is taken as P, and the distance from the edge portion of the central opening portion to the point P in the direction of the output shaft is taken as ?H, ?H/H?0.4 is satisfied. With this configuration, the formation of a vortex flow in the flow channel inside the impeller from the air inlet to the air outlet is reduced, and, thus, air blowing efficiency is improved.

  • Publication number: 20090122366
    Abstract: An image forming apparatus is supplied which enables print medium to be simply taken out even if an interval between a print processing section and an image reading section is not sufficiently secured. In the image forming apparatus, an image reading section is furnished on the upside of a print processing section; an ejection opening is furnished between the image reading section and the print processing section for ejecting a medium that has been printed; a loading part is furnished between the image reading section and the print processing section and is used for loading the ejected medium. The loading part includes a body part, a movement member that is movable from the body part, and a guide section that guides the movement member to move from the body part along upward slant direction with respect to a horizontal plane.

  • Publication number: 20070015563
    Abstract: In a gaming machine according to the present invention, a main control circuit transmits, to a sub control circuit, a variable display pattern command which is indicative of the variable display pattern of identification information and identifies whether or not variable display of identification information should result in a specific display mode and a variable display result command indicative of the result of variable display of identification information. If the sub control circuit determines that the combination of the received variable display pattern command and the received variable display result command is a combination at the time of an error, it detects a predetermined error and notifies the result of the detection.

  • Patent number: 6865364
    Abstract: A fixing device (1) includes a fixing roller (11), a heating roller (12), an endless belt (13) stretched around the fixing roller (11) and the heating roller (12), and a pressure roller (14) facing the fixing roller (11) via the endless belt (13), and has an internal heat source. The endless belt (13) is applied the tension by means of a tension applying spring (17). The fixing roller (11) is supported by a swing lever (15) and pressed against the pressure roller (14). The swing lever (15) is pushed by a cam (18) upward, so that the fixing roller (11) shifts in the direction away from the pressure roller (14). As the fixing roller (11) shifts upward, the tension applied to the endless belt (13) decreases.

  • Patent number: 4892882
    Abstract: Compounds of formula (I): ##STR1## (wherein: R.sup.1 represents a hydrogen atom or a halogen atom;R.sup.2 represents a C.sub.1 -C.sub.6 alkyl group; andA represents an oxygen atom, a sulphur atom, a sulphinyl group or a sulphonyl group)have good insecticidal activity coupled with a low toxicity to warm-blooded animals. Compounds in which A represents an oxygen or sulphur atom can be prepared by reacting a corresponding alkali metal alkoxide or mercaptide with the corresponding 3-dimethylcarbamoyloxy-5-halomethylisoxazole derivative, while compounds where A represents a sulphinyl or sulphonyl group may be prepared by oxidizing the corresponding compound wherein A represents a sulphur atom. The compounds may be formulated with conventional insecticidal carriers or diluents and exhibit a synergistic increase in activity when combined with various known organic phosphate and carbamate insecticides.
