1200 V SiC IE-UMOSFET with low on-resistance and high threshold voltage
Shinsuke Harada,Yusuke Kobayashi,Akimasa Kinoshita,Naoyuki Ohse,Takahito Kojima,M. Iwaya,Hiromu Shiomi,Hidenori Kitai,Kyogoku Shinya,K. Ariyoshi,Yasuhiko Onishi,Hitoshi Kimura +11 more
TL;DR: In this paper, a SiC UMOSFET is developed to cope with the trade-off between low on-resistance and extremely low gate oxide field, which is known as gate oxide protection.
Journal ArticleDOI
Direct observation of the tympanic cavity by the superfine fiberscope
Hitoshi Kimura,Hideki Yamaguchi,Seishu Cheng,Tadao Okudaira,Atsushi Kawano,Naohisa Iizuka,Moriyoshi Imakirei,Sotaro Funasaka +7 more
TL;DR: A newly invented superfine fiberscope is reported which makes it possible to insert through the eustachian tube, and direct views of the middle ear structures on normal subjects and patients, and that no surgical intervention was necessary in the procedure.
Journal ArticleDOI

TL;DR: In this paper, a flip-type n-channel implantation and epitaxial (IE)-IGBTs were developed, and the static and dynamic performance of IE-IGBT was investigated.
Journal ArticleDOI
Audiological Findings in Patients with Essential Retrocochlear Lesions
TL;DR: Five cases of so-called retrocochlear deafness with impaired speech intelligibility in spite of nearly normal pure-tone sensitivity were presented, and it was supposed that the impaired speech perception might be due to interference with the precise neural timing relations required by such tasks.
Journal ArticleDOI
Cystic lesions of paranasal sinus with eye symptoms.
Hitoshi Kimura,Hideki Yamaguchi,Tadao Okudaira,Osamu Takahashi,Sotaro Funasaka,Naohisa Iizuka,Tunemasa Sato +6 more
TL;DR: Thirty patients with post operative paranasal cysts and ophthalmological symptoms were treated at Tokyo Medical College Hospital from January, 1984 to December, 1987, 18 males and 12 females and exophthalmos was the most prominent eye disorder.
