Made up of a step of preparing a map expressing a correlation between solid phase percentage and viscosity of a slurry-form semi-solid metal () for a given metal composition; a step of setting a target viscosity corresponding to a target solid phase percentage using this map; a viscosity measuring step of measuring the viscosity of a semi-solid metal in a vessel () while cooling it; and a step of carrying out cooling until this viscosity reaches the target viscosity, by these steps being carried out in from the preparation of the map expressing the correlation between solid phase percentage and viscosity of the semi-solid metal to the end of cooling of the semi-solid metal the solid phase percentage of the semi-solid metal is made to match the target solid phase percentage. Because the viscosity is detected, the affects of cooling rate changes and time can be eliminated, and it is possible to raise management accuracy of the solid phase percentage of the semi-solid metal much further than with related art management based on time.

Molding of slurry-form semi-solidified metal

An apparatus for simulating a ride on a vehicle has a base, and a simulated vehicle body which is supported on the base with a freedom of two-axis rotation about a rolling axis and a pitching axis. A pair of linear actuators are disposed in a position offset to one side in an axial direction of one of the rolling axis and the pitching axis, e.g., offset to one axial side of the rolling axis relative to the pitching axis. The actuators are disposed symmetrically relative to a plane which crosses the pitching axis at a right angle and which includes an axial line of the rolling axis. A fixing member and a movable member of each of the actuators are coupled to the base and the simulated vehicle body, respectively, through universal joints.

Apparatus for simulating ride on vehicle

An optical axis of a headlight of a vehicle is adjusted by picturing an illuminating pattern of the headlight to appear on a screen which is disposed in front of the vehicle. A position of a center of gravity of a region above a predetermined illuminance in the illuminating pattern is obtained. A position of a stepped region in which a stepped portion of a light/dark border line of the illuminating pattern is present is obtained. A position of a point of inflection, in the stepped region, of an iso-illuminance curve having a predetermined rate of illuminance relative to an illuminance in the center of gravity is measured. The optical axis is adjusted based on this point of inflection.

Method of adjusting optical axis of headlight of vehicle

That illuminating pattern of the headlight which appears on a screen disposed in front of the vehicle is pictured. The optical axis of the headlight is adjusted based on an image of the illuminating pattern. A distribution of illuminance of the illuminating pattern along a scanning line which bridges a light portion and a dark portion of the image of the illuminating pattern is measured. A position of a reference point which serves as a reference in adjusting the optical axis is obtained from that point on the scanning line which corresponds to a crossing point of a first straight line and a second straight line. The first straight line is obtained from a portion corresponding at least to one of the light portion and the dark portion of a curve which represents the measured distribution of illuminance. The second straight line is obtained from a portion corresponding to a transient region which is positioned between the light portion and the dark portion.

A riding simulation apparatus comprises a color picture image signal generating apparatus for outputting video image information of a forward field of view of the rider and video image information of the rear of the rider, a display apparatus for receiving the video image information outputted from the color picture image signal generating apparatus, masking a picture image based on the video image information of the rear of the rider and reflecting a video image based on the image information of the forward field of view of the rider on a flat screen provided at a position forwardly of the rider, and a pair of left and right liquid crystal television sets provided at the positions of back mirrors of the simulation motorcycle for receiving the video image information of the rear of the rider and displaying a picture image based on the video image information of the rear of the rider. A running mode selecting controller for selecting a specific running mode, a first control for controlling the behavior of the simulated motorcycle according to a selected specific running mode, and a second control for controlling a picture corresponding to the running mode by changing the contents of the picture according to the selected specific running mode may be included.

Riding simulation system

A synchronous operation control system for a numerically controlled machine such as a gear grinding machine or a hobbing machine includes a first motor for rotating a master shaft supporting a tool, a second motor for rotating a slave shaft, and a workpiece shaft operatively coupled to the slave shaft for supporting a workpiece which is to be machined by the tool. First and second encoders are coupled respectively to the master and slave shafts. Processors are provided for differentiating output signals from the first and second encoders with respect to time and thereafter calculating at least positional errors between the master, slave, and workpiece shafts. In addition, an adder is provided for adding output signals from the processors and applying an output signal to the second motor.
