摘要:
In order to fix an optical fiber to a desired position in a holding member easily and tightly, provided is an optical collimator (10) having a plastic optical fiber (13) and a cylindrical holder (11). The holder (11) is configured to hold a collimator lens (12) at an end and has an insertion hole (11a) at an opposite end for inserting the plastic optical fiber (13). The plastic optical fiber (13) is sandwiched by an inner surface of a recess (11e) which is formed at a part of the holder (11) in proper alignment with the collimator lens (12).
摘要:
A rechargeable battery pack attachable to a power tool includes a display element, a remaining capacity detection device, a remaining capacity display control device, an abnormality detection device, and an abnormality display control device. The display element is provided such that a lighted state thereof can be confirmed from outside. The remaining capacity detection device detects a remaining capacity of a rechargeable battery. The remaining capacity display control device displays the remaining capacity detected by the remaining capacity detection device by controlling the lighted state of the display element. The abnormality detection device detects an abnormality of the rechargeable battery. The abnormality display control device displays the abnormality of the rechargeable battery detected by the abnormality detection device by controlling the lighted state of the display element to an abnormality display state, which is different from a remaining capacity display state controlled by the remaining capacity display control device.
摘要:
An adapter for a power tool powered by a detachable battery pack which adapter includes a connector configured to detachably connect the adapter directly to the power tool, an adapter controller, at least one memory and/or storage device in communication with the adapter controller and configured to store maintenance information concerning the battery pack or to store maintenance information concerning the battery pack and the power tool, at least one communication port configured to transmit electrical communications, including said maintenance information, from the adapter controller to a controller located in the power tool and vice versa, and a transmitter configured to wirelessly transmit the maintenance information to an external device.
摘要:
In a load port apparatus, a door driving mechanism that supports a door through a communication opening portion leading to a mini-environment is housed in a housing chamber that is in communication with the mini-environment through the communication opening portion. Exhaust opening portions are provided in the upper portion of a wall of the housing chamber that is opposed to the communication opening portion and a bottom wall of the housing chamber. Thus, gas passages from the mini-environment to the housing chamber and then to the external space are formed. Thus, dust in the load port apparatus is removed.

摘要:
Each of a battery charger and a battery pack has a microcomputer. The respective microcomputers mutually perform data communication while the battery pack is being charged by the battery charger, and confirm an operational state of the microcomputer of the communication counterpart (mutual operation confirmation) based on a result of the data communication. When an abnormality of one of the microcomputers is detected, the other microcomputer executes a predetermined process for stopping charging.
