  • Publication number: 20240384116
    Abstract: The present invention provides an epoxy resin that has excellent curability, when a low-activity catalyst is used or when used at low temperatures, that has excellent storage stability, and that yields a coating material having excellent coating film finish properties and corrosion resistance. The present invention further addresses an object of providing an amine-modified epoxy resin produced by reacting the epoxy resin with an amine compound, as well as providing a cationic electrodeposition coating material containing the amine-modified epoxy resin. The solution provided is a modified epoxy resin produced by reaction of at least the following (i) and (ii) and having an average polyfunctionalization degree (X1) per molecule of the modified epoxy resin of 0.

  • Publication number: 20240364213
    Abstract: A switching circuit including: a switching device configured to conduct or open a state between a drain terminal and a source terminal; a drive circuit including a first switch element and a second switch element, the drive circuit being configured to open and close the first switch element and the second switch element, and output a drive voltage for driving the switching device to the gate terminal via an output end; a clamp circuit including a third switch element configured to conduct between a reference potential of the drive circuit and a connection point of a path connecting the output end of the drive circuit and the gate terminal; and a ferrite inductor provided immediately near the output end of the drive circuit, and having one end connected to the output end and the other end connected to the connection point.

  • Patent number: 12101018
    Abstract: A driving circuit for a switching element that drives a switching element of a current-driven type. The driving circuit includes a controller including a first terminal and a second terminal and that outputs a control signal to a gate terminal of the switching element. A first resistor, which regulates a current serving as the control signal, is connected to the first terminal, and a first capacitor is connected in parallel to the first resistor. A second resistor and a second capacitor are connected in parallel, and a current path extends from the first resistor and the first capacitor to the gate terminal and from a source terminal of the switching element to the second terminal of the controller. The second resistor and the second capacitor are in the current path.

  • Patent number: 5815143
    Abstract: A video picture written in the bit map memory (4) is displayed in a predetermined area on the display screen (70) of the display device (7) within the computer main body (100). The masking memory (2) having a bit number equal to or less than the number of the pixels of the video picture to be inputted is provided separate from the bit map memory (4). When the pixel data of the video picture data has been inputted, the input pixel data is selectively written in the bit map memory (4) based on the contents of the masking memory (2). In displaying a compressed picture of the input video picture on the display screen, an oblique line generating algorithm is used.

  • Patent number: 5652881
    Abstract: Still picture search/retrieval method and system for retrieving a still picture without omission by extracting representative color component from a location of the still picture which includes a thing for search. A search condition input processing module receives color information constituting a search condition via an input unit. A still picture dividing method determination processing module receives via the input unit a method for dividing the still picture into rectangular meshes of a same size. A divided mesh designation processing module receives designation of a mesh for search from those resulting from the division. Still picture information is read out from a database for dividing each still picture into meshes by a still picture division processing module. A representative color component extraction processing module extracts a color component having the highest frequency of histogram within the search-destined mesh.

  • Patent number: 5182676
    Abstract: A retractable turn-over type rearview door mirror in which angular adjustment of the mirror member can be effected by manually operating an actuation lever. By using a certain linkage mechanism, a favorable correspondence is achieved between the direction of movement of the actuation lever and the direction of movement the mirror member. The use of a clutch unit permits the adjusted state of the mirror member to be conserved, even when the rearview door mirror is retracted and restored, by minimizing the influences of the retracting movement upon the linkage mechanism. This can be accomplished by applying a suitable amount of friction to the linkage mechanism, but, by using a lock lever which fixes the angular orientation of the mirror member when the rearview door mirror is retracted, the angular orientation of the mirror member may be kept fixed without requiring such a friction and it allows the operation of the actuation lever to be performed with a small force.
