  • Publication number: 20190224417
    Abstract: Certain embodiments of the present invention relate to a pharmaceutical injection device, and it is an object thereof to optimize the mixing of pharmaceutical in a pharmaceutical cartridge. To achieve this object, a pharmaceutical injection device may comprise a main case, a piston, a drive motor, a buzzer, and a controller. The main case has a cartridge holder. The piston is inserted into a pharmaceutical cartridge mounted to the cartridge holder. The drive motor drives the piston. The buzzer emits a sound that tells the user to shake the pharmaceutical cartridge to mix or dissolve its contents. Before activating the drive motor and injecting the pharmaceutical, the control unit controls the buzzer so that a sound is emitted at specific intervals to prompt shaking.

  • Patent number: 7369218
    Abstract: An analysis apparatus capable of normally creating image data and an analysis disc used for this. Instead of using a signal which has been read in time series by pickup following a track so as to create an image by utilizing address information engraved on an optical disc, a mark (110) is recorded over the radius direction (A) of a read area (109) of the analysis disc (108) where an analysis object (B) is arranged, at least at a preceding position or a following position of the read area (109) in the rotation direction (C), so that video processing aligned according to this mark is executed, thereby executing video acquisition or a shape count with a high accuracy.

  • Patent number: 7016281
    Abstract: An optical disc that has a recognition mark area behind a recorded area and in which the last data in the recorded area is stably accessed, the recognition mark area can be accessed without bringing about an abnormal state, and the first data in a succeeding recorded area, if it exists, is stably accessed. An unrecorded area (5) is provided outside the recorded area (4) of the optical disc (1). A mark area (6) is provided between the recorded area (4) and unrecorded area (5). A recognition mark area (6d) is provided in the mark area (6) in order to recognize the boundary between the recorded area (4) and the unrecorded area (5). In the mark area (6), first and second buffer areas (6b and 6c) are provided respectively in front of and behind the recognition mark area (6d).
