  • Patent number: 6380719
    Abstract: An integrated system for comprehensive control of an electric power generation system utilizes state machine control having particularly defined control states and permitted control state transitions. In this way, accurate, dependable and safe control of the electric power generation system is provided. Several of these control states may be utilized in conjunction with a utility outage ride-through technique that compensates for a utility outage by predictably controlling the system to bring the system off-line and to bring the system back on-line when the utility returns. Furthermore, a line synchronization technique synchronizes the generated power with the power on the grid when coming back on-line. The line synchronization technique limits the rate of synchronization to permit undesired transient voltages.

  • Patent number: 6381376
    Abstract: An image processing device includes an intermediate processing section for appending identification data to each pixel, showing a kind of region to which each pixel belongs, based on multi-value image data of a plurality of input images entered from a scanner, and a matching data generating section for generating matching data of each pixel. A CPU classifies the kind of region to which each input image belongs based on the identification data of each pixel stored into an identification data memory by means of a connection processing section, and compares the matching data stored in a matching data memory after processed adequately depending on the kind of region. Then, the CPU extracts matching points of the input images and connects the binary image data of the input images using the extracted matching points as reference points. Consequently, a plurality of input images can be restored to a single image by being connected accurately whether the input images are picture, shadow, or picture images.

  • Patent number: 6364462
    Abstract: An image recording apparatus includes a heating portion and a granulating portion to generate colorant particles, a charging portion to charge the generated colorant particles, an ejecting portion to intermittently eject the charged colorant particles onto a recording medium in response to an electrical signal corresponding to image data to be recorded, and a transport portion to sequentially transport the colorant particles through these portions. The heating portion heats and evaporates solid or liquid colorant. The evaporated colorant is transported to the granulating portion, cooled, solidified and agglomerated into colorant particles. The colorant particles are transported to the succeeding charging portion, charged there and transported to the ejecting portion. The charged colorant particles are electrically induced toward a recording medium through an ejection hole and ejected onto a recording medium, so that the colorant particles stick and permeates to the medium according to image data.

  • Patent number: 6366334
    Abstract: The purpose of the present invention is to provide a method for manufacturing a liquid crystal display device which can easily remove a removal part even from the liquid crystal display device using substrates made of thermoplastic resin. The liquid crystal display device is constructed by sticking the first and second substrates made of thermoplastic resin to each other using a sealing material. A dividing line is formed on the first substrate by a dicing method which is a half cut with a predetermined remaining thickness so that the removal part within the first substrate becomes easy to be removed. A jet of compressed air is emitted into between the first substrate the half cut is performed on and the second substrate so as to lift up the removal part. The jet of compressed air is emitted in the diagonal direction toward the liquid crystal display device. When the jet of compressed air is emitted, a removal head is inserted between the removal part and a terminal area so as to remove the removal part.
