  • Patent number: 11911850
    Abstract: A pillar delivery method is a method for delivering a plurality of pillars onto a substrate, including a glass panel, to manufacture a glass panel unit. The pillar delivery method includes an irradiation step, a holding step, and a mounting step. The irradiation step includes setting, over a holder, a sheet for use to form pillars and irradiating the sheet with a laser beam to punch out the plurality of pillars. The holding step includes having the plurality of pillars, which have been punched out of the sheet, held by the holder. The mounting step includes picking up some or all of the plurality of pillars from the holder and mounting the pillars onto the substrate.

  • Patent number: 11913277
    Abstract: A method for manufacturing a glass panel unit includes an assembling step, a bonding step, a gas exhausting step, a sealing step, and an activating step. The bonding step includes melting a peripheral wall in a baking furnace at a first predetermined temperature to hermetically bond a first glass pane and a second glass pane together with the peripheral wall thus melted. The gas exhausting step includes exhausting a gas from an internal space through an exhaust port in the baking furnace to turn the internal space into a vacuum space. The sealing step includes locally heating to a temperature higher than a second predetermined temperature, and thereby melting, either a port sealing material or an exhaust pipe to seal the exhaust port and thereby obtain a work in progress. The activating step includes activating a gas adsorbent after the sealing step to obtain a glass panel unit.

  • Patent number: 8576643
    Abstract: 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 a maximum variation width of a threshold voltage for memorizing an information set larger than that of the second nonvolatile memory area. The first nonvolatile memory area can be prioritized to expedite a read speed of the memory information, and the second nonvolatile memory area can be prioritized to guarantee the number of times of rewrite operation of memory information.

  • Patent number: 8171662
    Abstract: A method for processing a separation and rupture portion of a display label is a method for forming, on the display label attached to an attachment target object, the separation and rupture portion for rupturing the display label upon separation of the display label from the attachment target object. This method includes attaching, to the attachment target object, the display label having a back side on which an adhesive layer is formed, and then forming a slit serving as the separation and rupture portion on the display label.

  • Patent number: 8130571
    Abstract: 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.

  • Patent number: 7805562
    Abstract: 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.

  • Patent number: 7310700
    Abstract: 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.
