Title: Powder concentration decision method for electric discharge machining liquid mixed with powder
Inventor: TAKAHASHI NOBUYUKI
IPC: G01J3/52
Filed: 1992-10-26
Abstract: PURPOSE:To allow easy and accurate measurement to be performed in a quite short time by comparing a reference spot formed on a filter paper by an electric discharge machining liquid mixed with a powder at a known concentration with a similar test spot formed by a machining liquid mixed with a powder at unkown concentration. CONSTITUTION:When a plurality of electric discharge machining liquids mixed with a powder at a known concentration is sampled by means of a filler and dripped on a filter paper, black spots (reference spots) having different gradations can be obtained due to the difference of powder concentration in a quite short time. On the other hand, a black spot (test spots) of electric discharge machining liquid mixed with a powder at unknown concentration to be measured is formed on the filter paper by the similar operation. When the black color of the test spot is compared with that of the reference spot and an identical or an approximate spot is selected, powder concentration of the test spot can be decided. When the powder concentration is in the range of 0.20-2.00wt.%, the power concentration can be determined quantitatively basing on the gradation of the black color.

Abstract: PURPOSE:To maintain the contact pressure of a slider to be constant and to stably operate a slide table by a specified driving force by obtaining a contact pressure of the slider in pressure-contact with a transmission rod, from a constant-load elastic member or constant fluid pressure. CONSTITUTION:A piezoelectric vibrator 1a is excited by application of a high frequency voltage, a transmission rod 2 is fixed to the piezoelectric vibrator 1a, and a slider 3 is in pressure-contact with the transmission rod 2. By exciting the piezoelectric vibrator 1a, one way progressive wave is produced on the transmission rod 2, and this progressive wave generates a driving force, in a direction opposite to that of propagation of the progressive wave, on the slider 3. This driving force moves the slider 3 in a direction opposite to that of propagation of the progressive wave. A contact pressure of the slider 3 in pressure-contact with the transmission rod 2 is obtained from a constant-load elastic member, the load of which is constant independent of stroke, or a fluid pressure controlled to be constant. This enables the contact pressure of the slider 3 to be always constant, and the slider 3 can be operated by a stable driving force.
