A method and a device for electrochemically machining workpiece having blade end plates at the longitudinal both ends of a blade-shaped portion having aerofoil shape in cross section by extending and retracting divided electrodes. A part of the blade-shaped portion and one blade end plate continued therewith are electrochemically machined by advancing the main electrode in an acute angle direction relative to the longitudinal direction of the blade-shaped portion. At the same time or subsequently, the remaining part of the blade-shaped portion and the other blade end plate continued therewith are electrochemically machined by slidably advancing an auxiliary electrode along the slope of the main electrode forming an acute angle relative to the blade-shaped-portion-machining-surface. Thus, the number of the parts of an electrode unit can be reduced and the structure thereof can be simplified.

A rotation detection sensor for inhibiting the invasion of high temperature and high pressure fluid includes a holder, a detection element, a case body, and a housing. The tip end portion of the holder at which is located the detection element is accommodated in the case body and the rear end portion of the holder is covered by the housing. A first groove accommodating a first O-ring is formed on the external peripheral surface of the holder, and a second groove accommodating a second O-ring is formed on the external peripheral surface of the holder toward the tip end side relative to the first groove. A method for forming the sensor involves positioning the case body and the holder in a recess portion of a die, and injecting resin into the die to form the housing covering the rear end portion of the holder.

A rotation detecting device for detecting a rotation number and a rotation direction of a rotating member based on at least two detection signals having different phases from each other and output from at least two sensor elements provided on the rotating member so as to face each other includes a waveform processing means for performing a waveform processing on the detection signals based on one of a plurality of predetermined conversion rules, a setting signal receiving means for receiving a setting signal for determining the predetermined conversion rule to be used from the plurality of predetermined conversion rules, and a conversion rule setting means for determining the predetermined conversion rule to be used based on the setting signal received by the setting signal receiving means.
摘要:
A threshold value at a side of a bottom value of a sensor signal is renewed by a value calculated by multiplying a minimum value of a deviation between the bottom value and a reference value for the predetermined period of time by a ratio when the minimum value of the deviation is equal to or smaller than the threshold value. A threshold value at a side of a peak value thereof is also renewed by a value calculated by multiplying a minimum vale of a deviation between the peak value and the reference value from the predetermined period of time by a ratio when the minimum value of the deviation is equal to or smaller than the threshold value.
摘要:
An automobile antenna adapted to be mounted onto the roof of an automobile and which includes an antenna body portion formed with antenna receiving grooves which is adapted to be mounted onto the roof of the automobile with suitable suction cups or magnets mounted on the bottom of the antenna body and including a pair of rod shaped telescoping antennas which in a stored position are received in the antenna receiving grooves and which are movable to a second position to form a predetermined V-shape. Locking mechanisms lock the rod antennas in the antenna receiving grooves when in the stored position and means are provided for holding the rod antennas in the extended position when in use.
