Publication number: 20230251327Abstract: In an embodiment, a diagnostic apparatus of an electric power converter is provided, and the electric power converter outputs a converted AC electric power to an electric motor, thereby driving the electric motor. The diagnostic apparatus includes an output control unit and a degradation determination unit. The output control unit controls operations of semiconductor elements of the electric power converter, thereby outputting electric power from the electric power converter to the electric motor by constant voltage output, which constantly sets an output voltage to the electric motor in a target voltage pattern. The degradation determination unit determines a degradation state for at least one of the semiconductor elements based on a current flowing through the electric motor in the constant voltage output.Type: ApplicationFiled: December 9, 2022Publication date: August 10, 2023Inventors: Toshimitsu Aizawa, Shinichi Kominato, Tsuyoshi Shinohara, Kohei Hasegawa

Publication number: 20180279810Abstract: A support has a loading surface that is formed for placement of a merchandise. A guide is disposed around the support and along an outer circumference of the loading surface. A drive unit changes a disposition of a main mechanical unit from a first disposition to a second disposition. A level of the support relative to the guide in the second disposition is lower than the level of the support relative to the guide in the first disposition. The main mechanical unit in the first disposition supports a bottom of a bag with the loading surface, while the bag with a bag mouth facing downward is put on the support and the guide from above. The main mechanical unit puts the merchandise into the bag by allowing a side periphery of the bag contiguous to the bottom of the bag to stand upward from the bottom of the bag via the guide by changing the disposition of the main mechanical unit from the first disposition to the second disposition.Type: ApplicationFiled: October 5, 2016Publication date: October 4, 2018Applicant: Panasonic Intellectual Property Management Co., Ltd.Inventors: RYOJI INUTSUKA, SHOZO FUKUSHIMA, MASATOMO KITADA, NAOYA HABA, TSUYOSHI SHINOHARA, KAZUYA HIROSAKI
