In a complex tool to be installed on a machine tool capable of turning machining and milling machining operations, a main body is provided, and carries inserts for turning machining, inserts for milling machining and inserts for drilling machining. Turning machining and drilling/milling machining operations can be executed using the inserts installed on the main body, without the need for tool exchange, saving time and labor. The inserts as installed have opposite rotational cutting directions, ...

This invention relates to a complex of eletriptan and a sulphobutylether-beta-cyclodextrin, or a pharmaceutically acceptable salt thereof, and to processes for the preparation of, pharmaceutical formulations including, and the uses of, such a complex.

An embodiment of a complex lens (1) includes a central substrate (10), two opposite glass layers (12), and two opposite IR-cut layers (13). The substrate is made of transparent plastic, such as polycarbonate or polymethyl methacrylate. The glass layers are deposited on opposite surfaces of the substrate. The IR-cut layers are deposited on surfaces of the glass layers. The substrate has a spherical or an aspheric surface. The IR-cut layers have a function of filtering infrared rays, thereby impro...

A complex tool has a main body and a turning tool provided at an outer periphery portion of the main body. The turning tool is capable of machining on a rotating workpiece without rotating itself. An insert installed on the turning tool has a top end which contacts a workpiece by projecting a predetermined amount outside the main body's outer peripheral face. It also projects a predetermined amount from a top end portion of the main body in a direction of an axial center of the tool. The complex...

Complex multiplication is performed using a multiplier by generating time division signals with a first clock and a second clock having a speed twice as fast as the first clock and operating the multiplier in a time division mode by the time division signals. Using a first clock and a second clock, the time division signals delayed by one-forth cycle are generated during one cycle of the first clock. Real element and imaginary element of two complex numbers are stored in D flip flops. A multiple...

A multifunctional complex incorporates multiple uses and comprises a series of upright wall members including a first interior wall dividing the complex into at least a concert hall. The concert hall includes a stage structure excavated below ground level, a truncated annular dance floor surrounding the stage structure also excavated below ground level and a series of truncated pie-shaped audience seating sections radiating upwardly from the dance floor in which the lowest tier of open seating i...

A metal complex and its use for binding or cleaving a nucleic acid. The metal complex has the formula: ##STR1## M is Pt, Pd, Ni, Co, or Cu; X is aryl, heteroaryl, cyclyl, or heterocyclyl; Y is halogen, tosylate, mesylate, triflate, pyrophosphate, or carboxylate; each of A.sub.1 and A.sub.2, independently, is N or C; each of A.sub.3 and A.sub.4, independently, is N, S, or O, wherein A.sub.1, A.sub.2, A.sub.3, and A.sub.4 taken together have one positive charge; and each of R.sub.1 and R.sub.2, in...

A copper complex coordinated with a Schiff base is provided herein, which complex is especially advantageous to catalyze the asymmetric synthesis of alkyl chrysanthemates. The specific complex of the present invention is a copper complex coordinated with a chiral Schiff base of the formula: ##STR1## wherein C* is an asymmetric carbon atom, R.sup.1 is selected from (a) alkyl groups whose carbon atom number is 1-10, and (b) aralkyl groups with or without alkoxy substituent(s), whose total carbon a...
