A compressor includes a cylinder block having a compression chamber therein, a piston arranged in the compression chamber which reciprocates up and down, and a driving mechanism which drives the piston. The driving mechanism includes an elastic member whose peripheral portions are fixed to the cylin
A compressor includes a cylinder block having a compression chamber therein, a piston arranged in the compression chamber which reciprocates up and down, and a driving mechanism which drives the piston. The driving mechanism includes an elastic member whose peripheral portions are fixed to the cylinder block so as to allow the elastic member to oscillate up and down, and whose center portion is attached to the piston, and one or more piezoelectric actuators that are arranged on the elastic member. In response to a power, one or more piezoelectric actuators repeatedly deform and apply an exciting power to the elastic member.

The capture of the narrow binding margin panel by the distal tip of the clasp jaw engaged at the junction between the sheets of the material forming the binder prevents the slide bar from being pulled laterally off of the binding edge of the stack. of CBN or diamond is sandwiched by a first layer and a third layer consisting of a tool material such as cemented carbide. Prismatic blanks of rectangular cross-section are cut out by cutting the three-layer laminate in strips. Semi-completed tips of a desired shape are obtained by cutting up the prismatic blanks. Desired cutting edges are formed on the semi-completed tips to produce completed tips. Because prismatic blanks are obtained from a three-layer laminate and semi-completed tips are cut out from the prismatic blanks like this, the semi-completed tips can be obtained in large numbers, yield is high, and the manufacturing cost of the tip can be reduced. upta, S., Gittins, S., Picherack, P.,"Insights into Some Key Issues with Solvent Aided Process", Petroleum Society--Canadian Institute of Mining, Metallurgy & Petroleum, Paper No. 2001-126, pp 1-23, Jun. 12-14, 2001.
