Abstract: The adhesiveness of a treatment target made of a fluorine-based hard-to-adhere material is improved. A process gas containing any one or two or more among carbon monoxide, carbon dioxide, hydrogen, water vapor, ethanol, propanol, hexanol, ethylene glycol, and ammonia is supplied from a process gas supply unit 10 to a plasma generation unit 20. In the plasma generation unit 20, the process gas is activated by plasma and is brought into contact with a treatment target 9, and through a reaction caused by the contact, the residual ratio of fluorine atoms on a surface of the treatment target 9 is adjusted to 60% or less of that before the contact, and any one among a carbon atom, a hydrogen atom, and an oxygen atom, or a molecule containing one or more of these atoms is provided to the surface of the treatment target.

Abstract: A forward direction line is set on a course, in a virtual game world, on which a player object is allowed to move. An advancing direction at a current position of the player object is determined based on the forward direction line. The advancing direction is determined as a direction in which the player object advances so as to control a movement of a player character in accordance with an acceleration instruction, and a leftward-rightward movement instruction from a player. Consequently, it is possible to assist the player in controlling a direction in which an object operated by the player moves.

Abstract: Each time a player hits either one of right and left strike surfaces of a conga controller, it is determined whether: the right strike surface has been hit continuously; the left strike surface has been hit continuously; or the right strike surface and the left strike surface have been hit alternately. When the right strike surface has been hit continuously, a character in a game world is caused to move rightward. When the left strike surface has been hit continuously, the character is caused to move leftward. When the right strike surface and the left strike surface have been hit alternately, the character is caused to accelerate. Based on the above, a game program and a game apparatus, which are capable of giving various action instructions to the character of the virtual game world by using continuous inputs by a plurality of switches, can be provided.

Abstract: Sound generated by handclaps of a player is converted into an electric signal by a microphone, and the electric signal is inputted to a game apparatus. When a jump instruction is inputted, a player character jumps. However, the character jumps in accordance with the handclaps of the player only when the character is positioned on a jump ramp set in a virtual game world. In a case where ambient noise is inputted through the microphone when the character is not positioned on the jump ramp, the player character does not jump, but performs a provocative action. The provocative action does not exert any influence on a movement of the player character. Thus, in an action game for causing the player character to perform a predetermined action in accordance with a sound input, it becomes possible to prevent the player character from performing an action which is not intended by the player, even if the sound input is mistakenly detected.
