Publication number: 20240186151Abstract: An object is to provide a display device with excellent display characteristics, where a pixel circuit and a driver circuit provided over one substrate are formed using transistors which have different structures corresponding to characteristics of the respective circuits. The driver circuit portion includes a driver circuit transistor in which a gate electrode layer, a source electrode layer, and a drain electrode layer are formed using a metal film, and a channel layer is formed using an oxide semiconductor. The pixel portion includes a pixel transistor in which a gate electrode layer, a source electrode layer, and a drain electrode layer are formed using an oxide conductor, and a semiconductor layer is formed using an oxide semiconductor. The pixel transistor is formed using a light-transmitting material, and thus, a display device with higher aperture ratio can be manufactured.Type: ApplicationFiled: February 7, 2024Publication date: June 6, 2024Inventors: Shunpei YAMAZAKI, Junichiro SAKATA, Masashi TSUBUKU, Kengo AKIMOTO, Miyuki HOSOBA, Masayuki SAKAKURA, Yoshiaki OIKAWA

Patent number: 5399302Abstract: A parison length control method for a blow molding machine in which a parison is extruded vertically, the end of the parison is closed, and a blowing gas is blown into the closed parison. The method includes the step of deriving a relationship between parison length and extruder screw rotation speed during a test molding process. Current parison length is then detected during normal molding operation, and the difference between the current parison length and a target parison length is derived. The extruder screw rotation speed is then controlled by calculating a correction amount for the extruder screw rotation speed based on the parison length difference in combination with the relationship between parison length and extruder screw rotation speed. The extruder screw rotation speed is then adjusted by the correction amount so as to attain the target parison length.Type: GrantFiled: December 22, 1992Date of Patent: March 21, 1995Assignees: Kao Corpoation, Tahara Machinery LimitedInventors: Tokuji Noguchi, Masashi Yano, Masayuki Akimoto, Mitsuo Yamanoi, Minoru Ohizumi

Patent number: 5198161Abstract: A parison thickness control system includes an extruder die and a mandrel which are movable relative to each other to change wall thickness of a parison extruded between the extruder die and the mandrel during an extrusion or forming cycle of the parison. A parison control pattern is derived by manually inputting master points each defined in terms of a target parison wall thickness and an elapsed time during the parison extrusion cycle. A further parison control pattern is derived by performing the spline interpolation to interpolate between the master points. A still further parison control pattern is derived by correcting the above-noted further parison control pattern to allow the maximum or minimum value of the master points to indicate a limit value for the target parison wall thickness during the parison extrusion cycle. The parison extrusion cycle is divided into a given number of equal time intervals to define cycle points.Type: GrantFiled: March 5, 1991Date of Patent: March 30, 1993Assignees: Kao Corporation, Tahara Machinery Ltd.Inventors: Masashi Ogura, Yutaka Saito, Masayuki Akimoto, Minoru Oizumi
