    摘要： This invention discloses an electronic device with electricity recording function and an electricity recording method thereof. The electronic device comprises a power module, a gauging module, a storage module and a processing module. A type and a level of the power module are gauged by the gauging module and stored by the storage module during a buffering time before the electronic device is shut down. When the electronic device is powered on, the processing module is used to take the type and the level of the power module from the storage module for reducing the waiting time of the electronic device when it is powered on.

    摘要： Captive washers are used with tension control devices on a drum having a drum shell, two drum hoops, two drumheads and multiple tension control devices. Each tension control device is mounted on the drum shell and has a mounting post, a connector and two adjusting bolts. Each captive washer presses against the drum hoop and has a flange, a lip, an annular groove and a through hole. The annular groove is formed between the flange and the lip and is mounted securely in an elongated groove in the drum hoop to hold the captive washer in the drum hoop. The through hole extends longitudinally through the captive washer.
