Patent number: 12098587Abstract: A glass panel unit includes: a first panel including a glass pane; a second panel including another glass pane; a sealing portion; an exhaust port; and a printed portion. The second panel is arranged to face the first panel. The sealing portion is formed in a frame shape and hermetically bonds respective peripheral edge portions of the first and second panels to create an evacuated, hermetically sealed space between the first panel and the second panel. The exhaust port is provided for one panel selected from the first and second panels. A port sealing member hermetically seals the exhaust port. The printed portion is provided for the other panel selected from the first and second panels. The printed portion is located in an area, facing the exhaust port, of one surface of the other panel. The one surface either faces toward, or faces away from, the hermetically sealed space.Type: GrantFiled: August 27, 2019Date of Patent: September 24, 2024Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Kenji Hasegawa, Eiichi Uriu, Kazuya Hasegawa, Tasuku Ishibashi, Hiroyuki Abe, Masataka Nonaka, Takeshi Shimizu, Haruhiko Ishikawa

Patent number: 12091359Abstract: A sealing head includes a frame, an intake unit, a pressing pin, and a non-contact heater. The frame is configured to be detachably attached to a work in progress of a glass panel unit. The intake unit, the pressing pin, and the non-contact heater are supported by the frame. The work in progress includes a first substrate, a second substrate, a bonding part, and an internal space. The first substrate has an evacuation port. The bonding part bonds the first substrate and the second substrate together. The internal space is formed by being surrounded by the first substrate, the second substrate, and the bonding part. The internal space is communicated with the evacuation port. The pressing pin is configured to press, toward the second substrate, a sealing material which is heat fusible and which is inserted into the evacuation port. The non-contact heater is configured to locally heat the sealing material in a non-contact manner via the second substrate.Type: GrantFiled: February 28, 2019Date of Patent: September 17, 2024Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Haruhiko Ishikawa, Takeshi Shimizu, Masataka Nonaka, Eiichi Uriu, Kazuya Hasegawa, Tasuku Ishibashi, Hiroyuki Abe

Patent number: 12043574Abstract: A glass panel unit manufacturing method includes a bonding step, an insertion step, an evacuation step, and a sealing step. The bonding step includes bonding a first substrate having an evacuation port and a second substrate with a bonding material having a frame shape to form an internal space. The insertion step includes inserting a sealing material into the evacuation port. The evacuation step includes evacuating the internal space by connecting an exhaust device to the evacuation port and driving the exhaust device. The sealing step includes sealing the evacuation port with the sealing material while an evacuated state in the internal space is maintained. In the sealing step, a measured value by a pressure gauge is monitored while the sealing material is heated, softening of the sealing material is detected based on the transition of the measured value, and heating of the sealing material is stopped.Type: GrantFiled: April 15, 2019Date of Patent: July 23, 2024Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Takeshi Shimizu, Masataka Nonaka, Haruhiko Ishikawa, Eiichi Uriu, Kazuya Hasegawa, Tasuku Ishibashi, Hiroyuki Abe

Patent number: 8130571Abstract: A semiconductor integrated circuit has a central processing unit and a rewritable nonvolatile memory area disposed In an address space of the central processing unit. The nonvolatile memory area has a first nonvolatile memory area and a second nonvolatile memory area, which memorize information depending on the difference of threshold voltages. The first nonvolatile memory area has the maximum variation width of a threshold voltage for memorizing information set larger than that of the second nonvolatile memory area. When the maximum variation width of the threshold voltage for memorizing information is larger, since stress to a memory cell owing to a rewrite operation of memory information becomes larger, it is inferior In a point of guaranteeing the number of times of rewrite operation; however, since a read current becomes larger, a read speed of memory information can be expedited.Type: GrantFiled: June 16, 2011Date of Patent: March 6, 2012Assignee: Renesas Electronics CorporationInventors: Yutaka Shinagawa, Takeshi Kataoka, Eiichi Ishikawa, Toshihiro Tanaka, Kazumasa Yanagisawa, Kazufumi Suzukawa

Patent number: 7805562Abstract: A microcomputer capable of on-board programming of dedicated user communication protocols without requiring a serial interface on the mounted board, and that will not destroy the dedicated user communication protocol code even if the system runs out of control. A user boot mat other than a user mat is provided for programming control programs for the user in the on-chip non-volatile memory of the microcomputer. The user boot mat serves as the mat for programming the dedicated user communication protocol and also provides a user boot mode for running the program. The user boot mat cannot program or erase in this user boot mode. By separating the user boot mat and user mat, an interface capable of programming and erasing the user-specified programming can be achieved without having to program a dedicated communication protocol on the user mat.Type: GrantFiled: August 23, 2007Date of Patent: September 28, 2010Assignees: Renesas Technology Corp., Hitachi Hokkai Semiconductor, Ltd.Inventors: Naoki Yada, Eiichi Ishikawa

Patent number: 7310700Abstract: The present invention provides a microcomputer wherein in a system which needs to respond to events developed at intervals each shorter than an erase/program process time, erase/programming can be effected on an on-chip non-volatile memory as necessary during its processing. An erase and program control program for an electrically erasable and programmable non-volatile memory is configured inclusive of a loop of the application of a high voltage pulse and data verify or the like, for example. If a program jumped to a subroutine for an address specified by a user is programmed in advance during this loop, then a process by a CPU can be temporarily jumped to the subroutine for the user defined address. Thus, erase and programming can be effected on a system which needs to confirm internal and external events every predetermined intervals or a system with a learning function, or the like during the execution of a user program.Type: GrantFiled: February 7, 2007Date of Patent: December 18, 2007Assignees: Renesas Technology Corp., Hitachi Hokkai Semiconductor, Ltd.Inventors: Naoki Yada, Eiichi Ishikawa
