Patent
Torque detecting apparatus
Hiroshi Kimura,Shotaro Naito,Kunio Miyashita,Yasuo Noto,Noboru Sugiura,Tadashi Takahashi,Hirohisa Yamamura,Seizi Yamashita,Syooichi Kawamata,Fumio Tajima,Shigeru Horikoshi +10 more
TL;DR: In this paper, the authors proposed a method for detecting load torque using angle detectors fitted with a certain spacing on a shaft which is rotated by a drive source and on the basis of a relative angular difference of angles detected by the angle detectors.
Patent

Haruo Koharagi,Kazuo Tahara,Tsunehiro Endo,Kunio Miyashita,Yoshitaro Ishii,Fumio Jyoraku,Syuji Watanabe,Hisanori Toyoshima,Kohichi Saito,Wakichiro Hishi,Koujirou Yamashita +10 more
TL;DR: In this article, the rotational speed of a variable speed fan motor adapted to give a suction force to a vacuum cleaner and its change range are discriminated, and a speed command of the fan motor is corrected on the basis of the result of the discrimination.
Patent
Permanent magnet electrical machine with reduced cogging
Fumio Tajima,Hiroshi Katayama,Kunio Miyashita,Teizo Tamura,Kenichi Hironaka,Takuro Kawano,Yoshimi Sekita,Kouichi Saito,Akira Tamura +8 more
TL;DR: In this paper, a group of grooves is formed between the salient magnetic poles having an interval of 2/3Mπ, with M being an integer which is not a multiple of three.
Patent
Device for detecting rotation of rotary shaft and rotation controlling apparatus using the same
Ryoso Masaki,Toshiyuki Koterazawa,Kazuo Tahara,Kunio Miyashita,Yoshikazu Hoshi,Tadashi Takahashi,Shuichi Nakano +6 more
TL;DR: In this article, a rotation detecting device for a rotary shaft and a rotation controlling apparatus using this rotary detecting device is described. But the rotary torque can be obtained by calculating a difference between the rotating angles measured at two points apart from each other on the rotial shaft.
Patent
Vacuum cleaner with fuzzy logic control
