Abstract: Disclosed is an operating device of a game machine which is installed in the game machine including a display portion which displays the progress of a game in accordance with a control of a body controller and a result of the game and operates the progress of the game in conjunction with a display on the display portion. This operating device includes a rotation operation portion capable of being rotated by a player, a rotation operation detecting portion which detects a state of rotation operation of the rotation operation portion, a decoration display portion which displays any one of a pattern, a symbol and a letter, or a combination thereof, and a connection portion which outputs a signal of the rotation operation detecting portion to the body controller and inputs a signal for controlling a display of the decoration display portion from the body controller.

Abstract: Provided is a game machine system including a game machine capable of progressing different kinds of games and a table games with different kinds of the games, the game machine system including an administration controller connected to a plurality of game machines and the game machine capable of displaying progress of a game selected from a plurality of kinds of games and a result of the game, in which the game machine includes an operating device with which a player operates the progress of the game, and the progress of the game connected to the administration controller is performed by operation of the operating device of the game machine selected by the administration controller.

Abstract: Disclosed are educational straws having an end portion of a defined shape and the name of said shape displayed on the exterior body of the straw thereby instilling a cognitive recognition of a sequence of letters associated with the shape which will enhance vocabulary, spelling and object spatial recognition for a plurality of defined shapes.

Abstract: Disclosed is a beverage container having an internal flexible straw having spaced apart flexure joints positioned to create pressure within the straw body so that when the pull tab is removed from its covering position of the beverage body port the stored energy within the straw flexure joint portions will extend the top portion of the straw through the body port opening into an operative position.

Abstract: Disclosed is to an easy-open envelope having a tear-line located within a length of the envelope's seam fastened to frangible portions of the envelope created by strategically placed perforations creating an envelope mailer with an integral opener that eliminates the need for using a knife or letter opener potentially damaging the envelope contents or using a finger which leaves the envelope ragged.

Abstract: A micro-welder, by which a superfine wire such as a lead wire can be welded on a desired position of a parent material with a minimum welding area, including: a power source having a capacitor-charging device for generating a predetermined voltage and a voltage controller for adjusting the level of voltage output from the capacitor-charging device; a charge-storing member connected in parallel to the power source for storing the voltage output from the capacitor-charging device; a switching member connected in parallel to the charge-storing means for conducting the voltage output from the capacitor-charging device; a switch driving member for turning-on the switching member; and a welding circuit connected in serial to the switching member.

Abstract: A heat-flux gage, a manufacturing method and a manufacturing device thereof which are improved from circular foil heat-flux gage disposed in ASTM E511 comprise: a cylindrical body having a receiving space therein, and a foil mounting hole on one end thereof; a foil including a heat absorption surface, an inner surface facing the heat absorption surface, and a radiant side surface connecting the heat absorption surface and the inner surface, wherein the inner surface faces toward the receiving space and the radiant side surface is contacted to a side surface of the foil mounting hole; a foil lead wire connected on a center of the inner surface of the foil; a body lead wire connected to an opposite end of the foil mounting hole on the cylindrical body; and a filler filled in the inner receiving space, to prevent the foil lead wire from being damaged by fixing the foil lead wire.
