Patent number: 11932787Abstract: A two-part curable adhesive composition includes a main agent (A) containing a urethane prepolymer (a1) and a remaining polyisocyanate (a2), and a curing agent (B) containing a non-crystalline polyol compound (b1) and a polyamine compound (b2). An equivalent ratio of an isocyanate group in a raw polyisocyanate to a hydroxyl group in the polyol compound is from 2.05 to 12. The equivalent ratio of the isocyanate group in the main agent (A) to an amino group in the polyamine compound (b2) is from 1.2 to 6. The equivalent ratio of the isocyanate group in the main agent (A) to the hydroxyl group in the non-crystalline polyol compound (b1) is from 2 to 12.Type: GrantFiled: September 27, 2019Date of Patent: March 19, 2024Assignee: The Yokohama Rubber Co., Ltd.Inventors: Kazushi Kimura, Hirokazu Kageyama, Yutaro Yamamoto

Patent number: 6399950Abstract: In a two-dimensional radiation detector of the invention, a semiconductor layer for converting a radiological image or light image converted therefrom to a picture image of charges by sensing X-ray, and a switching element matrix are integrally formed. A bias electrode common to a signal electrode of the semiconductor layer is connected to a bias power source through a switch or a resistance. An electric current flowing through the bias electrode from the bias power source is detected by a detector, and supplied to a control circuit. The control circuit compares a detected value supplied from the detector with a threshold value, and turns off the switch when the detected current value reaches the threshold value to shut off application of the bias voltage to the bias electrode.Type: GrantFiled: November 27, 2000Date of Patent: June 4, 2002Assignee: Shimadzu CorporationInventors: Yutaro Kimura, Takayuki Takemoto

Patent number: 5631944Abstract: The rotary cathode X-ray tube equipment of present invention is constructed so as to permit radiation of X-ray from all directions with respect to the whole circumference of a subject, and is used for x-ray CT. The equipment of the invention is constructed to prevent an X-ray radiation window 40 of a low strength from being influenced by atmospheric deformations of a vacuum vessel 1 or by machining and assembling errors, for example by using a joint portion disposed between the X-ray radiation window and an inner ring and having both a surface perpendicular to a rotational axis of a rotary member and a cylindrical surface parallel to the rotational axis, a face seal formed on the surface of the joint portion perpendicular to the rotational axis, and an axial seal formed on the cylindrical surface of the joint portion parallel to the rotational axis.Type: GrantFiled: August 28, 1996Date of Patent: May 20, 1997Assignees: Shimadzu Corporation, Mitsubishi Denki Kabushiki KaishaInventors: Yutaro Kimura, Tetsuhiko Ikeshima, Hiromichi Tonami, Ikuo Konishi, Hiroshi Horikawa, Akihiro Daikoku, Shigekazu Sakabe, Masao Inoue, Akinori Yamasaki

Patent number: 5515411Abstract: An X-ray image pickup tube converts a transmitted X-ray image into electric signals. The pickup tube includes a target structure having a fluorescent element, and a translucent conductive film for receiving a high voltage, with a photoconductive film laminated thereupon. The fluorescent element receives transmitted X rays in a two-dimensional distribution, and converts them into visible rays in a two-dimensional distribution. The translucnet conductive film is optically coupled to a surface of the fluorescent element opposite from an X-ray incident surface thereof. The photoconductive film includes an amorphors semiconductor layer which converts the visible rays transmitted in a two-dimensional distribution through the translucent conductive film, into electric charges in a two-dimensional distribution, and which multiplies the electric charges in the two-dimensional distribution based on electric fields formed by the high voltage applied to the translucent conductive film.Type: GrantFiled: March 22, 1994Date of Patent: May 7, 1996Assignees: Shimadzu Corporation, Nippon Hoso KyokaiInventors: Hiromichi Tonami, Takahisa Nishikawa, Takayuki Takemoto, Yutaro Kimura, Keiichi Hiragaki, Hidetoshi Kishimoto, Tatsuya Shimizu, Shiro Oikawa, Tutomu Katou, Shirou Suzuki, Toshio Yamagishi, Kenkichi Tanioka
