Publication number: 20240107854Abstract: The thickness of a display device including a touch sensor is reduced. Alternatively, the thickness of a display device having high display quality is reduced. Alternatively, a method for manufacturing a display device with high mass productivity is provided. Alternatively, a display device having high reliability is provided. Stacked substrates in each of which a sufficiently thin substrate and a relatively thick support substrate are stacked are used as substrates. One surface of the thin substrate of one of the stacked substrates is provided with a layer including a touch sensor, and one surface of the thin substrate of the other stacked substrate is provided with a layer including a display element. After the two stacked substrates are attached to each other so that the touch sensor and the display element face each other, the support substrate and the thin substrate of each stacked substrate are separated from each other.Type: ApplicationFiled: December 11, 2023Publication date: March 28, 2024Applicant: Semiconductor Energy Laboratory Co., Ltd.Inventors: Shunpei YAMAZAKI, Yoshiharu HIRAKATA, Kensuke YOSHIZUMI

Patent number: 7744594Abstract: A catheter for treating arrhythmia comprises a catheter shaft of a double-cylinder structure where an inner shaft is slidably inserted in an outer shaft, a balloon installed so as to straddle between the tip portion of the inner shaft and the tip portion of the outer shaft, a pair of high frequency current-carrying electrodes of which at least one electrode is provided inside the balloon, and a temperature sensor for monitoring the temperature in the balloon. The front edge portion of the balloon at least in a deflated state protrude from the tip portion of the inner shaft. Alternatively, a tube that is more flexible than the inner shaft is provided on the tip portion of the inner shaft.Type: GrantFiled: August 20, 2003Date of Patent: June 29, 2010Assignee: TORAY Industries, Inc.Inventors: Yoshiharu Yamazaki, Motoki Takaoka

Patent number: 7052507Abstract: A catheter with a balloon for mitral valve formative operation includes a double tube having an inner tube and an outer tube disposed concentrically. A balloon is fastened at one end to the inner tube and at the other end to the outer tube. A balloon-extending pipe stopper is disposed at the tip of the inner tube and includes an entry diameter at one end sized to receive a balloon-extending pipe with an allowance. An inner diameter of the balloon-extending pipe stopper at an opposite end is smaller than the entry diameter. The inner diameter of the extending pipe stopper is substantially equivalent to a diameter of the balloon-extending pipe. In use, the balloon-extending pipe is inserted into the inner tube and brought into contact with the balloon-extending pipe stopper for axially extending the balloon for contraction in diameter.Type: GrantFiled: December 21, 2000Date of Patent: May 30, 2006Assignee: Toray Industries, Inc.Inventors: Hiroshi Wakuda, Masato Shimagami, Yoshiharu Yamazaki

Patent number: 5330429Abstract: A catheter with a balloon characterized by a balloon reinforced with a composite yarn consisting of an elastic yarn and a non-elastic yarn with a larger free length of the non-elastic yarn than that of said elastic yarn. When the catheter is inserted into a blood vessel or taken out on a surgical operation, the balloon is deflated to a small diameter without producing any wrinkle and is stretched by inflation to the same size and the same shape at any time. Therefore, reliability of the balloon catheter in surgical operation is improved and the cut wound in the surgical operation is smaller. Treatment and management after the surgical operation are simple and the time required for recovery is extremely short.Type: GrantFiled: January 8, 1993Date of Patent: July 19, 1994Assignee: Toray Industries, Inc.Inventors: Noriyasu Noguchi, Yoshiharu Yamazaki, Mitsuyuki Hagio, Yasuhiko Futami
