To overcome the problem of offset images in electrophotography when using a heated roller in fixing a toner image, a toner composition containing a non-linear polyester resin is used. The polyester resin is made from 1-60 mol % polyhydric alcohol having at least three hydroxy groups and 2-65 mol % of a polycarboxylic acid having at least three carboxy groups.

The controller of the gaming machine executing processing operations of: (a) determining a magnification of a respective one of plural kinds of colors which are produced in a color displayable manner by means of the multiple color light emitting backlight and then displaying on the display; (b) determining a light emitting color by means of the multiple color light emitting backlight and then controlling light emission in the determined color; and (c) executing a payout of a number which is obtained by multiplying the magnification that corresponds to the color determined in the processing (b), from among the magnifications of the respective colors, the magnifications being determined in the processing (a), for a payment that corresponds to the pattern of the specific symbols.
摘要:
According to a gaming machine 1 of the present invention, a specific number of free games are generated when three or more trigger symbols 100 have been stop-displayed in a normal game. Further, when one or two trigger symbols 100 have been stop-displayed in a free game, numeric values in number equivalent to the number of stop-displayed trigger symbols 100 are selected, and then the number of times obtained by summing up the selected numeric values is added to the number of free games.

摘要:
A vehicle front structure of the present invention includes a hood ridge extended along a fore-and-aft direction of a vehicle in an upper edge portion of a vehicle front, a front side member extended along the fore-and-aft direction of the vehicle in a lower edge portion of the vehicle front, and a strut housing located between the hood ridge and the front side member. Further, the structure includes a hood ridge lower front portion composed in a manner that a rear edge portion thereof is connected to a front-side surface of the strut housing, and that an upper edge portion thereof and a lower edge portion thereof are connected to the hood ridge and the front side member, respectively. The hood ridge lower front portion has a hood ridge lower front outer member and a hood ridge lower front inner member. The hood ridge lower front inner member is provided to be spaced from the hood ridge lower front outer member at a predetermined interval and forms a closed cross section together with the hood ridge lower front outer member.
