Abstract: A biological signal is obtained from a player, under a situation where a biological parameter can be calculated based on a biological signal repeatedly obtained from a sensor attached to a player, and a predetermined game processing can be performed using the biological parameter. Then, whether the sensor is attached to the player is determined based on the biological signal, and the predetermined game processing is performed in at least one of a case where the sensor attachment determining means determines that the sensor has changed from its attached state to its detached state and a case where the sensor attachment determining means determines that the sensor has changed from its detached state to its attached state, according to the timing at which the determinations is made.

Abstract: A video game apparatus includes a CPU, and the CPU executes a game according to a game program in a virtual space. During the game, the player selectively displays a 2D game screen and a 3D game screen by operating a controller. It should be noted that a player character, etc. is subjected to a modeling process in a virtual three-dimensional space, and the image is photographed by a virtual camera so as to be displayed as a 2D or 3D game screen on a monitor. If it is determined whether or not the player character and the predetermined object are contacted with each other, collision data for 2D display or collision data for 3D display set in advance to the object is utilized.

Abstract: An excavator of the invention comprises an excavating body having an excavating element and a clinometer detecting an inclination angle of ditch wall in a excavating ditch; a traveling distance recorder for measuring moving distance of said excavator; a calculator for calculating and accumulating the inclination signal for every moving distance of said excavator on the basis of the inclination signal outputted from said clinometer and the moving distance signal outputted from the traveling distance recorder; and a display device for displaying accumulated said inclination signal outputted from said calculator, thereby can excavate the ditch with excellent flatness of the ditch wall.

Abstract: The present invention provides a work control system for a trencher type excavator for soil cement wall, wherein in controlling the work of forming a soil cement wall carried out in the procedure such that a cutter post provided on a trencher type excavator for soil cement wall and having a chain cutter wound endlessly is inserted into the object ground, the cutter post is rotated while discharging a ground filler out of a discharge opening provided in the cutter post, and the cutter post is moved in a lateral direction of the ground, execution width of the soil cement wall based on a fixed work load, and filling quantity of the ground filler at each position of the soil cement wall forming work are displayed on a two-dimensional coordinate in a lateral axis and a longitudinal axis, respectively.

Abstract: A method is set forth for use in crown control in a multi-roll rolling mill, the method including the steps of: setting in advance a shape of a thermal crown of a work roll corresponding to various rolling conditions and a changing gradient of a mechanical crown for each rolling speed zone applied to a work roll which is determined according to a change in time of a thermal crown relative to a change in rolling speed; applying a roll bending force, as an initial value, to the work roll, controlling the roll bending force from the thermal crown shape and an initial value of a mechanical crown amount at a suitable position of the work roll which is determined from an expected rolling schedule and a target mechanical crown amount at a standing speed; detecting the rolling speed; selecting the changing gradient of the mechanical crown according to the rolling speed zone at that time; and at the same time adjusting the roll bending force applied to the work roll.
