  • Publication number: 20240113793
    Abstract: A purely-lateral position estimation unit (1603) estimates as an estimated purely-lateral position, when a disturbance wave to disturb communication performed in a train is generated while the train is traveling, a position existing in a purely-lateral direction with respect to a position of a generation source of the disturbance wave. A feature extraction unit (1604) extracts a feature of a measured reception power value being a reception power value measured in the train during a disturbance wave generation period wherein the disturbance wave has been generated.

  • Publication number: 20230238070
    Abstract: A semiconductor device includes a storage element write unit including a storage element configured to be electrically written only once and store two values, a write controller connected to the storage element through a first node signal and configured to perform a write to the storage element based on a write control signal instructing a write to the storage element, and a write state detection circuit configured to detect that the storage element is in a write state based on a measurement signal obtained by measuring the first node signal. In a case where the write controller receives a detection signal indicating that the storage element is in the write state from the write state detection circuit after start of a write to the storage element, the write controller stops write operation after a lapse of a predetermined time from detection of the write state of the storage element.

  • Patent number: 7850110
    Abstract: The drag adjusting device is provided with a pin member 70 arranged on a plate-like member 80 of a reel unit 1 such that it can be attached to and detached and such that its position can be changed. The pin member 70 serves to remember a prescribed pivot position of a drag mechanism operating member 2. When an angler finds an optimum drag lever position, the angler installs the pin member 70 in a mounting recess 81 corresponding to the optimum drag lever position. In this way, the angler can easily set the drag mechanism operating member 2 to the optimum drag lever position without having to remember the drag lever position.

The information communication unit is adapted for receiving second information concerning fishing from a fish finder or a GPS through a fishing information display device and an information coordinating unit. A second display unit of the fishing information display device can display the first information concerning the reel obtained from the reel and the second information concerning fishing with one of the first and second information being superimposed on the other. In this fishing reel, a large amount of information can be displayed while the size of the reel is kept small. Also, information concerning fishing can be obtained quickly.
