  • Patent number: 10633138
    Abstract: A printing apparatus includes a print head, a first cutter and a processor. The print head performs printing on a printing medium. The first cutter cuts the printing medium on which the print head has performed the printing. The first cutter trims away a corner at an end in a width direction of the printing medium. The processor controls the print head and the first cutter based on cutting information on an area to be trimmed by the first cutter so that a printing area of the printing medium is not cut by the first cutter.

  • Patent number: 10166802
    Abstract: A stamp-face platemaking device transports a medium holder inserted into a plate insertion portion to a printing unit. The medium holder holds a stamp face material in a plate-like member, and has a predetermined pattern in a side end portion thereof. An optical sensor detects the top end portion of the medium holder on a sensor scanning line in the inserting direction, and the pattern start point and the pattern end point of the predetermined pattern. At least one of the horizontal and vertical sizes of the stamp face material is set based on the positions of two of the detected end portions. When the pattern end point is detected, platemaking with the stamp face material is started.

  • Patent number: 9610665
    Abstract: A stamping-face plate holder is provided. The stamping-face plate holder comprises a plate holding member formed with a positioning recess for receiving and positioning a stamping-face plate and a film for covering the stamping-face plate held in the plate holding member. The stamping-face plate is made of a porous material impregnated with ink. The plate holding member consists of a top paper board and a bottom paper board, both boards being integrated by adhering and the positioning recess is formed in the top paper board. The film covers the whole surface of the top paper board and adheres to the top paper board excepting the stamping-face plate held therein.

  • Patent number: 9020260
    Abstract: CPU performs a process to obtain image data, and defines a predetermined range in the obtained image data. Further, CPU extracts outlines of images falling within the predetermined range, and selects a closed line among the extracted outlines. Then, an image processing unit and CPU converts an image surrounded by the selected closed-line into a painterly rendering image.

  • Patent number: 8870738
    Abstract: A cardiac function variation evaluation apparatus includes: a continuous flow type auxiliary artificial heart 20 connected to a ventricle (10A); a pressure sensor 30 for detecting ventricle (10A) internal pressure; and means (a personal computer 40) for evaluating contractile variation of the ventricle, to which the auxiliary artificial heart 20 is connected, based on internal area APMp of a closed-loop of a relationship between the ventricle internal pressure detected by the pressure sensor 30 and a consumption power of the auxiliary artificial heart 20. Thus, the contractile variation of the ventricle, to which an auxiliary artificial heart is connected, can be continuously evaluated not by use of an ultrasonic echo apparatus or a conductance catheter but by use of a non-invasive method.

  • Patent number: 7938588
    Abstract: A size-reduced printer that conveys a recording sheet in a circulating manner along a ring-like conveyance path while printing a plurality of images on the recording sheet in different colors sequentially in a superimposed manner, thereby forming a full color image. When a ribbon cassette that contains a multi-color ink ribbon is loaded at a predetermined position within a printer housing, a ring-like conveyance path is formed between the ribbon cassette and the printer housing. While the thermal head is driven and the recording sheet is conveyed once in a circulating manner along the conveyance path, a one-color image is printed on a previous printed one-color image in a superimposed manner in a corresponding one of the different color inks of the multi-color ink ribbon, thereby forming a full color image finally.
