  • Publication number: 20190099871
    Abstract: A driving tool drives a fastener by a striking mechanism. The driving tool includes a trigger, a contact arm, a contact lever and a regulator. The trigger and the contact arm receive manipulations which operate the striking mechanism. The contact lever is movable according to operations of the trigger and the contact arm and switches operating states of the striking mechanism. The regulator regulates a movement of the contact lever according to a movement of the contact arm in which another manipulation is released. The regulator operates with a fluid for operating the striking mechanism, and keeps the contact lever at an operation standby position where the contact lever is operated by manipulation of the contact arm for a predetermined time period by controlling a flow rate of the fluid.

  • Patent number: 6449986
    Abstract: In a method of manufacturing a porous glass preform for an optical fiber which preform is formed as a deposit of fine glass particles by using a burner, a method to prevent the contamination of any glass particles having failed to be properly deposited so that the generation of voids may be minimized in a transparent glass preform which is produced by heating the porous glass preform. An inert gas is caused to flow through the burner at a rate of at least 25 m/s before fine glass particles are formed by the hydrolysis and/or oxidation of a glass material in a flame produced by the burner supplied with a mixture of a gas of the glass material and a gas for combustion and are deposited on a rotating starting member. It is desirable to elevate the pressure of the inert gas above the atmospheric pressure by a device connected to the burner by a pipeline, and cause it to flow rapidly through the burner.

  • Patent number: 5915356
    Abstract: In a prescribed low-speed rotation region where a control rack is maintained in a prescribed low-speed side designed position, when a detected position (output voltage) of a rack sensor is offset towards the high load side than the position (voltage) written in a memory, the detected position is written in the memory. In a prescribed high-speed rotation region where a control rack is maintained in a prescribed high-speed side designed position, when a detected position of the rack sensor is offset towards the high load side than the position written in a memory, the detected position is written in the memory. The output characteristic of the rack sensor is calculated based on the detected position written in the memories, and the low-speed side and the high-speed side designed positions. The position of the control rack is calculated from the detected position based on this output characteristic.
