In this research, in educational coffee roasting machine, a parallel type hole was made in the plate installed between stove and rotating drum, and the effect of the perforating ratio of plate (R = 0, 7, 20[%]) on the temperature of the roasted coffee bean was investigated. The temperature was measured with an infrared camera. The temperature rise of roasted coffee beans can be accelerated as of increasing the influence of heat transfer by changing perforating ratio of plate R. Although gas consumption can be suppressed, it became clear that the rapid temperature rise of coffee beans is not always a good condition for coffee roasting.

Under the influence of Covid-19, many different types of masks were developed and produced, but most of them were based on common head shapes or were simply cut from materials. By using an individual's unique shape, the product made will be unique to that person, and the enjoyment of manufacturing can be expected. In addition, there are no examples of education that uses digital devices developed in recent years to obtain the shape of an individual. Therefore, this paper reports on the search for a simple and inexpensive method of acquiring shapes that can be used in education, and an attempt to design and prototype a highly functional mask for oneself.

In manufacturing education, it is desirable to have an education that guides students to think what they want to do, seek a way to realize it, and realize it. However, 1st graders do not have enough knowledge to think about what they want to do. And even if they come up with what they want to do, their skills often cannot catch up. Therefore, the authors conducted a lesson in which students introduced a simple electric vehicle that can be manufactured within a limited class period as a teaching material. In this paper, we report the outline.

With the rapid technological progress in recent years, training engineers with practical skills is a major issue. On the other hand, our university has introduced PBL education on the subject of automobiles and is working on improvement. Here, you can learn how to design a car with basic mechanics so that you can design and manufacture an automobile from scratch. On the other hand, there remains a problem that the concept cannot be realized in the actual experience that involves design and production. Therefore, we applied a thinking method such as the logical breast method and examined how to solve the problem.

"Manufacturing" is an important thing that supports modern society, but in modern times it is difficult to understand its importance. The Toyota Commemorative Museum of Industry and Technology aims to widely convey "manufacturing" to society and contribute to the development of society. Currently, the automobile production technology exhibition zone is being renovated into a new exhibition that adds "experience type" to "exhibition type". This time, in the first case of setting up the "painting training experience corner", we looked back on the purpose, the process leading up to the exhibition, and the reaction after the exhibition. As a result, we succeeded in understanding that "manufacturing", which is the purpose of setting up a new corner, is based on "human ability improvement" and that the current life is supported by human power. As a future task, it was pointed out that it was necessary to build a system to train guide members who could understand and explain the purpose of the exhibition.

Measurement engineering includes a wide range of natural sciences. In recent years, sensing technology has developed and the types of measuring equipment have increased. The basics of measurement, which is to properly process the numerical values obtained from the measuring equipment, are universal. In this paper, we report an attempt to incorporate Excel exercises as a practical opportunity for measurement engineering. Complicated calculations are required to utilize the theory in the real world. Therefore, software skills are required. Creating opportunities to practice theory can be expected to be a bridge between theory and practice.

On-demand type distance learning was carried out in the intermediate level class of computer programming for undergraduate students in fundamental science and engineering through a semester. Learning materials, a set of slides describing the key knowledge on focused points in exercises with explaining voices, were provided by the learning management system. In the exercises, the students made source codes of the C language according to given specifications and completed codes were submitted with a web page interface. Editing and submitting were repeated until all of the codes were accepted by the teacher. The status of the code submission and the result of the final examination suggest that the polarization of understanding appears among the students in the online class. The answers to the questionnaire show that no opportunity to discuss each other for the coding work is a demerit of such distance learning.

The author has tried to improve the lesson by using an interactive lesson method. Under the circumstances of the corona, we conducted a full online class, and conducted a flipped classroom and a class that adopted the sink pair sharing method. In this report, we will consider whether the lessons conducted were effective based on the confirmation of comprehension level by the minute paper filled out by the students for each lesson and the lesson evaluation by the student questionnaire.

Kobe City College of Technology department of mechanical engineering was starting the new curriculum from 2017. In the new curriculum, 3D CAD and 3D printing lecture in machine practice subject was start for the second grade students from 2018 because of necessary skill for mechanical engineer. On the other hand, it is difficult to introduce a large number of full-scale CNC machines into the machine practice subject because of their size and price. In this study, we attempt to establish CAM and small CNC milling machine education environment by adopting open source 3D modeler software CAM workbench for machine practice subject.

The authors have developed a teaching material to understand the structure and principle of gears by using CG animation materials. However, it is difficult for younger children who have low cognitive ability to understand only visual information to understand the structure of gears with CG contents. In this study, we developed a teaching material of gears to promote the understanding of the structure by touching the object, which cannot be supplemented by visual information alone. In this teaching material, the gears can be attached to any place on the board by using Velcro or strong magnets on the shaft of the gears, so children can learn the principle of gears while playing.

In this paper, the author proposes a new concept to examine the present affair with many problems, standing with a point of view on the phrase "visit from the past to the future" advocated by the technology and social division of the Japan Society of Mechanical Engineers. By the way, time flows with the past, the present, and the future, and the history of technology examines the background and society of the technology developed in the past, and solves problems for the present and the future. It is based on the past and present and is viewed the future. By replacing "problem solving" with "challenge", and it will be approached in the future. Future history is a category of research and study for examining the future situation by trans-looking the past, present and future. The concept has been discussed in the present paper.

Many of the machine elements are made of wood in the Pre-modern Ages in Japan, which makes material processing including wood cutting work technologically important. Wood cutting work, usually provided in a divisional system, differs from metal cutting work, mainly provided by smiths, and manufacturing in a composite system can also be provided including material processing of some composites made of both metal and wood, or material processing with machinery. The aim of this series of papers is to study how material processing and manufacturing was provided in the Pre-modern Ages in Japan.

In order to discuss the preserve and utilization of the items recognized as The Mechanical Engineering Heritage by JSME, which has been done since 2008fy, seven recognized items located in Fukuoka Prefecture are surveyed and reported. All the items are good condition and satisfied situation of the utilization except for two items. In spite of the existence of these exceptions, the activity on MEH are considered to be still significant to understand mechanical engineering and the history of machine and that of mechanical engineering.

The engineering ethics committee which is in Technology and Society divisiona of JSME has opened an engineer ethic seminar since 2008 every year. In this report, the theme of the past seminar is looked back on. Then the situation of the recent seminar is also arranged. From these results, the engineer ethic education of the near future is reviewed.
