IPC: G01B21/30
Filed: 1989-11-06
Abstract: PURPOSE:To remove the distortion of an image resulting from the change of the amplitude of a needle by providing a means for vibrating the needle and a means for maintaining the frequency/amplitude of the needle constant at all times. CONSTITUTION:A needle 1 is vibrated when an alternating voltage V (frequency (f)) of an oscillator 3 is impressed to a piezoelectric body 2. As the needle 1 is in touch with a sample 4 more strongly, an electromotive force of the frequency (f) of a piezoelectric plate 5 is increased. A feedback circuit 6 detects the electromotive force of the piezoelectric plate 5, takes out and rectifies a voltage of the components of the frequency (f), and maintains the distance between the needle 1 and sample 4 constant by a minute driving mechanism 7 so that the voltage is kept constant. Moreover, the needle 1 is moved along the surface of the sample 4 by the action of the circuit 6 and a scanning circuit 8, and the locus of the needle is indicated at a display part 9. Further, the mechanism 7 is provided with a piezoelectric plate 10 to detect the vibration of the piezoelectric body 2. A feedback circuit 11 detects an electromotive force S of the piezoelectric plate 10, rectifies a voltage of the components of the frequency (f), and controls an output voltage V of the oscillator 3 so that the voltage is maintained constant. Accordingly, even when the resonance frequency of the vibrating body is changed as a result of the deformation of the mechanism 7, the amplitude of the needle 1 is kept constant.

IPC: B23B47/00
Filed: 1998-09-02
Abstract: PROBLEM TO BE SOLVED: To obtain a mixture which is safe and shows better cooling efficiency and higher drilling efficiency than water by mixing a solvent and water in a specific ratio and filling the mixture into an aerosol can or a container other than a high pressure gas container for use. SOLUTION: Water as a base agent is mixed with 5-59 vol.% of a water soluble organic solvent to produce a liquid mixture which is usable as a coolant for wet drilling capable of taking heat and being easily volatilized by decreasing specific heat, a boiling point and specific gravity. The water soluble organic solvent includes ethanol, isopropanol, acetone, ethyl acetate and the like and the use thereof increases drilling efficiency much more than the use of only water. When a hole having a 25 ϕ diameter and a depth of about 100 mm is bored in an edge boundary concrete block with a super drill under a press load of about 30 kg, a boring time in case of using a coolant containing 60 vol.% of an organic solvent such as ethanol or the like is reduced to 86-101 seconds, while the boring time in case of using only water is 192 seconds.
