  • Publication number: 20190015044
    Abstract: A portable electronic device includes: a detection unit which detects at least one of biological information and motion information of a subject; a case which accommodates the detection unit; and a strap which fixes the case to the subject. The strap has a first surface which faces the subject when the case is fixed to the subject. The first surface is provided with a plurality of first protrusions, satisfying 0.03 mm?D?1.0 mm and 1<P/D?3, where P/D is a ratio of a pitch P representing a distance between centers of two of the first protrusions and an outer dimension D of each of the first protrusions.

  • Patent number: 9592675
    Abstract: There is provided a liquid fill container that is used to fill a liquid reservoir supplying a liquid to a liquid ejecting apparatus, with the liquid. The container includes a containing unit that contains the fill liquid; a filling port that is inserted into an inlet of the liquid reservoir, and that allows the liquid contained in the containing unit to flow therethrough to fill the liquid reservoir; and a positioning member that maintains the position of the filling port and the position of the liquid reservoir with respect to each other in the direction in which the filling port is inserted into the liquid reservoir during liquid filling of the liquid reservoir.

  • Patent number: 7492663
    Abstract: The present invention provides a storage device. The storage device includes a reset signal terminal, a clock signal terminal, a non-volatile memory, and a pull down resistance. The reset signal terminal is electrically connected to external equipment at a contact point, for receiving a reset signal. The clock signal terminal is electrically connected to the external equipment at a contact point, for receiving a clock signal. The data signal terminal is electrically connected to the external equipment at a contact point, for sending and receiving a data signal. The pull down resistance is connected to a lower side of electric potentials used by the storage device, at one terminal of the pull down resistance. The controller is initialized in response to the reset signal. The controller also writes to and reads from the non-volatile memory according to the clock signals and the data signals.

  • Publication number: 20080036828
    Abstract: [Object] To provide a liquid container allowing improvement of its dimensional precision. [Solving Means] An ink cartridge 22 as a liquid container includes a case 23 having a case body 30 and a lid case 32, and a moving member 36 attached to a surface of a flexible ink pack 25 housed in the case 23. The moving member 36 assumes different positional attitudes inside the case 23 in accordance with the volume of the ink pack 25 that is gradually reduced as the ink therein is consumed, so as to be detected by a detector provided in a printer when the moving member 36 assumes a positional attitude indicating that the ink pack 25 has become empty of ink. The case body 30, lid case 32, and moving member 36 are molded of a material containing at least polylactic acid to achieve a low mold shrinkage rate.
