The invention relates to a semiconductive resin composition containing at least two kinds of conductive fillers, wherein the difference in threshold values of percolation between at least two kinds of the conductive fillers is within a range of 10 to 50 mass %. The semiconductive resin composition of the present invention can be used widely in various form of molded products, such as component used for transport in a clean room, spin chuck, IC test socket, various rollers installed in copier, seamless belt, bearing, antistatic fiber, member for electrostatic coating, fuel tube, part around fuel or chemical tube.

Semiconductive resin composition

The invention relates to a heat-resistant sliding resin composition, comprising a vapor carbon fiber having a specific surface area of 10 to 50 m/g, a mean aspect ratio of 20 to 500 and a mean fiber diameter of 50 to 200 nm and a synthetic resin, wherein a heat deflection temperature under high load (ASTM D648) is 160&#xb0; C. or higher and a thermal conductivity is 0.8 W/mK or higher. The resin composition has heat resistance, heat-radiation property and sliding property. Particularly, the resin composition, which neither wears away nor abrades a soft metal member which is a counter member under high temperature and heat generative conditions, can be employed for various sliding members such as bearings.

Heat-resistant sliding resin composition, production process and use therof

The invention provides a production method of a conductive polymer, comprising a step of blending a polymer in a state of a melt viscosity of 600 Pa&#xb7;s or less at a shear rate of 100 swith a vapor grown carbon fiber in 1 to 15 mass at a mixing energy of 1,000 mJ/mor less, and a conductive polymer obtained thereby. Preferably, a vapor grown carbon fiber used has an outer fiber diameter of 80 to 500 nm, an aspect ratio of 40 to 1,000, a BET specific surface area of 4: to 30 m/g, a do02 of 0.345 nm or less according to an X-ray diffraction method, and a ratio (Id/Ig) of 0.1 to 2 wherein Id and Ig each represent peak heights of a band ranging from 1,341 to 1,349 cmand a band ranging from 1,570 to 1,578 cmrespectively, according to a Raman scattering spectrum. According to the invention, an excellent conductivity can be attained by compounding vapor grown carbon fiber in a smaller amount than in a conventional method.

Electrically conducting polymer and production method and use thereof

A loop track for racing objects is disposed at the center of a race game device, for example for a simulated horse race. A plurality of racing objects, such as race horses, run on the track. The X- and Y-directional positions of the race horses are detected by a separable position detecting means underlying the track. The separable position detecting means allows for easier maintenance, transport, assembly, and disassembly of the device. Information regarding the positions of the horses is displayed on a game screen. Players can write memos to themselves on individual game screens by pressing a trace over the game information on the game screen. A control unit provides game information corresponding to other races other than a current race, including future races, and players may select information corresponding to future races on the individual game screen.

Race game device

A loop track for race horses is disposed at the center of a horse race game device. Twelve race horses run on the track. A gate is disposed in a paddock in the track. The gate is advanced to a start point of the track from the paddock. Twelve satellites are disposed on three sides of the track. A large projector for displaying images of developments, etc. of a race is disposed on one of the short sides of the track. Speakers for live broadcasting, fanfares, BGM, etc. are disposed on both sides of the large projector. The horse race game device enables a larger number of running objects to be raced at once, whereby race developments are made more amusing.

A progressive gaming system pays out a progressively increasing bonus to a player who wins a game with a predetermined winning combination. The progressive gaming system includes a plurality of gaming controllers which detect when a player gets one of a plurality of predetermined winning combinations and pays out a predetermined number of coins or tokens according to the winning combination. Each of the gaming controllers counts coins or tokens bet by the player before the game is started and outputs an indication signal of the amount of the bet coins or tokens. The progressive gaming system further includes an master controller operatively connected to the plurality of gaming controllers, which adds a predetermined percentage of the bet coins or tokens reported by each of the gaming controllers to a bonus value, performs a lottery when the player gets a predetermined winning combination, and controls each of the gaming controllers to pay out coins or tokens corresponding to a predetermined reward for the predetermined winning combination and saved bonus value.

Gaming system that pays out a progressive bonus using a lottery

This invention relates a game machine in which a combination of characters stopped along a winning line is judged based on a winning table showing winning combinations of characters to determine the presence of a win and a payment of coins. In this game machine, a substitutable character can be used as another character, and when its substitution makes a combination of characters a winning combination, a payment of coins for the combination is increased or decreased to determine a new payment of coins.

Slot machine with payout modifying symbols

The present invention provides a slot machine for determining winning or losing by selecting predetermined symbols from symbol trains arranged on X reels, in accordance with a random number, in which the X reels have symbol trains of different numbers of symbols arranged thereon.

Clot machine

This invention relates to a slot machine which comprises random number generating unit and X reels each having a plurality of symbols. All the combinations of the symbols among the reels made when one symbol of each reel is selected are identified by respective numbers, and one random number is generated by the random number generating unit, so that a combination of the symbols bearing an identification number corresponding to the random number is selected.
