]]> Good will Mission from Michigan State, USA visited our factory https://www.myppj.com/en/information/good-will-mission-from-michigan-state-usa-visited-our-factory.html Mon, 11 Sep 2017 07:00:38 +0000 http://myppj.com/?p=4568 もっと読む→]]> Today, university people from Michigan Goodwill Mission visited our Kusatsu factory of PPJ (Pulsed Power Japan laboratory ltd.), through the introduction of Shiga Prefecture Industrial Support Center.

 

Shiga prefecture and Michigan, both of which have great Lakes, joined together to form a sister state relationship in 1968, celebrating its 50th anniversary next year.

 

The original important matter was the exchange of information and knowledge about conservation and development of natural resources in Michigan and Shiga prefecture.

 

Every year Michigan and Shiga send goodwill missions alternately, and currently promote the interactions in three fields; “culture ・art・ sports”, “youth” and “economy”.

 

This year, which is an odd year, the mission of Michigan was sent to Shiga Prefecture.

A commemorative ceremony will be held in Michigan next year, when the sister state relationship will mark its 50th anniversary.

 

We are really honored that people from the long-established mission visited us and we wish the good relationship of Michigan-Shiga sister state will continue on forever.

We also would like to contribute to the industrial development of Shiga prefecture and international technological development.

Over 30 years experience & achievement in Pulsed Power Technology

Concept

PPJ will support the development of the science and technology. Additionally, We will contribute to protect all of the global environment and enrich people’s livings by offering the technology with safety generation and control of the extreme situation; Pulsed Power.

Corporate Principles

  • We cooperate with research laboratories such as universities and national research institutes. We will systematically do the Maintenance, the development, and the succession of the pulsed power technology in our country.
  • We always try to study, and to create new social needs in development and the improvement of the technology.
  • We try to collect overseas technical intelligence, and always aim at the top technological level of the world.

Message

I have studied pulse power technology at Nagaoka University of Technology, and have developed a large number of pulsed power systems for many research institutions.
Our company is young and small, but We can provide the excellent technical service which specialized in the further state-of-the-art pulse power technology.
Our hope is that we contribute to development of technology with the clear technology based on the experience and the achievement for over 40 years of the high voltage, large current pulsed power devepolment.
Moreover, it cooperated with the universities and the research institutes engaged in research of pulse power technology, and I aim at becoming a pivotal organization which achieves systematically maintenance, development and  succession of the pulse power technology in Japan.
