A driving tool includes: a body provided with an outlet where a fastener is driven; an urging member attached to the body; and a plunger movable in a projecting direction toward the outlet by extension of the urging member. An urging force in the projecting direction acts on the body from the urging member when the urging member is extended.

Driving tool

A driving tool includes: a plunger movable in a launch direction of a fastener; an urging member that is extendable and contractible and is configured to serve as a drive source of the plunger; a moving member that is disposed at an end portion in an extension-contraction direction of the urging member and is movable in the extension-contraction direction of the urging member; a string-like member configured to connect the moving member and the plunger and transmit a driving force of the urging member to the plunger via the moving member; and a rotation prevention portion configured to prevent rotation of the moving member around a central axis in the extension-contraction direction of the urging member.

A driving tool includes: a plunger movable in a first direction along a direction in which a fastener is launched; an urging member that is extendable and contractible in the first direction and serves as a drive source of the plunger; and guide rails configured to guide movement of the plunger in the first direction. The guide rails extend along the first direction of the urging member and are disposed on both sides sandwiching the urging member, and the guide rails are arranged such that a virtual line connecting the guide rails on the both sides of the urging member is deviated from a central axis of the urging member in a plan view of the urging member as viewed from the first direction.

Provided are a vehicle data readout device and a vehicle data readout method with which it is possible to reduce power consumption in a state in which a vehicle has not been activated, even if the vehicle data readout device, which receives power from an in-vehicle power source, remains connected to the vehicle. Taking as a trigger a port voltage (Vp) of a readout communication line exceeding a voltage threshold (THv), a vehicle data readout device switches a change-over switch from off to on, to generate a pull-up state by means of a pull-up resistor, and initiates a read-out of operation parameter data (Dp) by a computer.

Vehicle data readout device, and vehicle data readout method

A diagnostic device, in accordance with a marker condition setting function, sets marker conditions for adding markers to collected data. Next, the collected data are read out from a data collecting device. Next, in accordance with a marking function, markers are added to the collected data at points in time when the set marker conditions are satisfied. Then, in accordance with a file creation function, with reference to the markers of the collected data, the collected data that took place within a predetermined time range before and after the markers is extracted, and the collected data is stored in individual analysis files.

Vehicle diagnostic system, vehicle diagnostic method, and diagnostic device

A fastener driving machine includes an actuator which injects a fastener to a driving target object, a controller which controls an operation of the actuator, and a sensor which detects a physical quantity changed by a contact with the driving target object. The controller controls the actuator based on the physical quantity detected by the sensor.

A storage condition setting device searches, from among a plurality of ECUs that reside within an in-vehicle network, for a target ECU corresponding to a diagnostic item that is input to an input unit. In the case that such a target ECU exists, the storage condition setting device acquires from the target ECU equipment information of a vehicle related to storage conditions that correspond to the diagnostic item, and selects and sets as storage condition data in the target ECU only those items that correspond to the equipment information from among the storage conditions.

Storage condition setting device and data storage system for vehicle diagnosis

A data collecting apparatus sets types of target ECUs, and stores, in a storage unit, driving parameter data items, which are capable of being output by a plurality of ECUs, in association with IDs of the plurality of ECUs. Subsequently, for each of the aforementioned types, a query is made to a vehicle as to whether an installed ECU exists, and the installed ECU is identified as a target ECU. Thereafter, based on the ID of the installed ECU, driving parameter data items capable of being output by the installed ECU that was identified as the target ECU are set as collection items.

Vehicle diagnostic data collecting apparatus, vehicle diagnostic data collecting method, vehicle diagnostic machine, and vehicle diagnosing method

An internal combustion engine diagnostic device and an internal combustion engine diagnostic method identify an abnormal cylinder having an abnormal air-fuel ratio among a plurality of cylinders during the operation of an internal combustion engine. The internal combustion engine diagnostic device comprises: an air-fuel ratio control unit for changing the air-fuel ratio in a stepwise manner by controlling a fuel injection amount adjusting means that adjusts the fuel injection amount of each of the plurality of cylinders; and an abnormal cylinder identification unit for identifying an abnormal cylinder on the basis of the relationship between each air-fuel ratio changed in a stepwise manner and the number of misfires occurring in the plurality of cylinders, the number being counted by a misfire counter for each air-fuel ratio changed in a stepwise manner.

According to a method and an apparatus of the present invention for diagnosing a fault of an engine, a cranking rotation state is created by rotating a crank shaft while explosions in each cylinder are stopped; a variation of angular velocity of the crank shaft is detected for each cylinder in the cranking rotation state; a cylinder the compression pressure of which is insufficient is detected based on the variation; and if a cylinder indicated as a misfiring cylinder by a fault code is the same as the cylinder detected as being insufficient in compression pressure in the cranking rotation state, the cylinder is specified.
