Game machine, game control method, and computer readable storage medium

A game system is provided that can control power-feeding of a power-feeding device according to playing of a game. In a game system that executes an arcade game and that is provided with a power-feeding device that feeds a personal terminal device, it is determined whether or not the arcade game is being executed, and the power-feeding function of the power-feeding device is controlled on the basis of the result of that determination.

Game system and game control method

A game system is provided that is capable of imparting a novel game sensation to the user by operating together with a means that selects at least one option from among several options. In a game system, with which a lottery game in which at least one option is selected from a plurality of options, and a chain game in which the progression of the game changes on the basis of the game result of the first game are executed, in the chain game, region data is generated for arranging, in a plurality of game progression regions, a plurality of selectable regions that are linked to the plurality of options; and the region data is updated so as to set certain game progression regions as being acquired regions, on the basis of the options selected in the lottery game.

It is possible to select plural types of drawing games in accordance with a condition and to provide a game player with the selected drawing games. A game device () for performing a bingo game for drawing either a first prize or a second prize with a ball Band a ball Bincludes an outer bingo stage () for drawing either the first prize or the second prize with the ball B, an inner bingo stage () for drawing either the first prize or the second prize with the ball B, supply means for supplying the drawing medium, which is either the ball Bor the ball B, to a predetermined transporting path, medium type specifying means for specifying if the drawing medium is the ball Bor the ball B, first feeding means for feeding the ball Bto the outer bingo stage () when the game medium supplied to the predetermined transporting path is the ball B, and second feeding means for feeding the ball Bto the inner bingo stage () when the drawing medium supplied to the predetermined transporting path is the ball B

Gaming device and its control method

In an injector having three concentrated fuel spray bands, one of the fuel spray bands is directed to an spark plug, and the others are directed to curved grooves on a piston. The sprays that enter each groove advance along each groove, mutually collide substantially under the spark plug, and are ascended. Further, these spray bands are carried to the vicinity of the spark plug by a tumble flow and stable stratified air-fuel mixture is formed. As described above, stable and satisfactory stratified combustion can be made.

In warming up operation when the temperature of an engine is low, heat release in a combustion chamber is delayed by making ignition timing immediately before the top dead center of compression stroke or later. Hereby, exhaust gas including a large quantity of unburned HC, oxygen and carbon monoxide is exhausted into an exhaust passage. Then, the mixture of the HC, oxygen and carbon monoxide is accelerated by a turbulence generating means for generating turbulence in an exhaust flow mounted in the exhaust passage. Hereby, the HC is combusted in the exhaust passage, exhaust temperature is raised, resulting in that effective reduction of the HC. As the exhaust temperature is raised, it can activate earlier a catalytic converter for purifying exhaust.

Spark ignition engine and method of controlling combustion of the engine

A combustion control device and a method for a direct injection engine are disclosed wherein, when the engine is operating in the partial load range, the valve opening/closing mode of an intake valve and/or an exhaust valve is controlled so that exhaust gases remain in a combustion chamber; and control is performed such that fuel is injected from a fuel injection valve into residual exhaust gases at least once during the time period from the latter half of an exhaust stroke to the first half of an intake stroke in one combustion cycle, and that an air-fuel mixture is ignited in the latter half of a compression stroke thereafter.

Control device and control method for direct injection engine

An internal combustion engine which injects fuel directly into a cylinderand ignites air-fuel mixture formed in the cylinder, wherein each fuel injection of said internal combustion engine comprises a lead spraywhich moves faster and a main spraywhich moves slower, the lead sprayis oriented towards an ignition plug, and the air-fuel mixture made by pre- and main sprays is ignited twice or more. This invention of the above configuration can provide a simple and inexpensive direct cylinder injection type internal combustion engine which reduces abrasion of electrodes and consumption of electric power while assuring stable fuel combustions even when ignition timing is retarded.

Cylinder direct injection type internal combustion engine

A humanoid robot including upper limbs, lower limbs, and a trunk. Hip joints which connect the lower limbs and the trunk each possess degrees of freedom provided in correspondence with a hip joint yaw axis, a hip joint roll axis, and a hip joint pitch axis. The humanoid robot is a leg-movement-type robot which walks on two feet. By arbitrarily offsetting the hip joint yaw axes in a roll axis direction, the effects of the movement of the center of gravity occurring when the mode of use of the robot is changed are accommodated to in order to flexibly balance the weights of the upper and lower limbs. The waist is made more compact in order to form a humanoid robot which is well proportioned and which makes it possible to prevent interference between the left and right feet when the direction of a foot is changed. Accordingly, a robot which moves naturally and in a way sufficiently indicative of emotions and feelings using fewer degrees of freedom is provided.

A control apparatus for a direct injection engine having an intake valve, an exhaust valve and a fuel injection valve for injecting fuel directly into a cylinder of the engine and in which fuel injection by the fuel injection valve is performed during intake stroke or during compression stroke of the engine, has combustion stabilizing device for stabilizing combustion in the cylinder. The combustion stabilizing device has next operation mode determination device for selecting either an operation mode of recovering the combustion stability by fuel injection during intake stroke or an operation mode of recovering the combustion stability by fuel injection during compression stroke when a deteriorated state of combustion is detected in fuel injection during compression stroke.

The vehicle surroundings monitor detects the sizes and positions of obstacles, ditches and humans as well as the depths of the ditches to provide the driver with sufficient information to secure safety during driving. The pattern light projector receives an incoming laser beam and projects a light spot matrix in the form of a regular grating onto the monitored area. The camera photographs the light spot pattern on the monitored area and sends image signals to the data processor which processes the image signals to detect the presence of any obstacle, ditch or human. Based on the steering angle detected by the steering angle sensor, the path the car will take is predicted and a possible contact or collision of the car with the obstacle is detected beforehand. The buzzer, voice synthesizer and display device are used to alert the driver and indicate the presence of the obstacles, the possible contact with them and the location where the possible contact will occur.
