It has been argued that Japan lost its industrial competence during the 90's. At the dawn of the New Century, we have still been unable to escape this long stifling situation. Because of the lack of natural resources, the only way for Japan's restoration is a revitalization of the manufacturing industry, as defined by the culture of "co-relationship" The source of competitive advantage is nothing but human talent. To create an industry capable of overcoming global competition, we need an education revolution that aims at "diversity", though so far Japanese educational system has pursued uniformity. Shortsighted policy for economic growth is not enough for true recovery. From a long-term point of view that spans several decades, it is clear that we must invest in an educational revolution for the future.

The knowledge, which is fundamental by the graphic images of front view, top view and right-side view for the outline and the three-dimensional model preparation, is necessary for the students to use the three-dimensional model software.
The purpose of this paper is a development of the three-dimensional computer graphics software for the education and is to apply the software to the computer graphics education. As for the students, an experience can learn fundamental knowledge by using this software.
This software has the following educational effects.
(1) Students can understand the process to develop the three-dimensional model.
(2) They can grasp the graphic images of front view, top view and right-side view.
(3) The three-dimensional model can be expressed with the graphic image of every rotation angle in real time.
The author applied this software to actual computer graphics education, and could fulfill an original purpose.

In order to improve the lecture of the strength of material, I have been constructing some real experiments, which can be proceeded on a small desk during lecture time (90minutes). By the experiment, students construct things, think something, and find something by themselves. The presented desktop experiments can be carried out as easier and cheaper than the virtual experiments by using multimedia. In this paper, some results from the desktop experiment for the strength of materials are reported. Moreover, the lecture by associating the CAE tool and the desktop experiments is reported.

It is important to provide students with many experimental programs in control engineering upon which they understand the physical phenomena of control system and develop controller design skills. The experimental seesaw control system described in this paper includes a stepping motor as the actuator, and a combination of potentiometer and image sensing device to generate feedback signals for the seesaw angle and the roller position, respectively. The employed control methodologies are the minimum-time control and the optimum regulator, making comparative study with the human control performance. Human control action is executed by the aid of a joystick device.
