The etching of dielectric oxide ceramics and dielectric single crystal oxides, particularly perovskite ceramics, is executed by means of laser radiation in an atmosphere having a reducing effect.

An improved surgical instrument cartridge is described. The cartridge comprises a plurality of wound closure elements. Each element has a crown and two opposite side legs. The distal end of each leg of a wound closure element contacts the crown of the adjacent preceding element. The improvement comprises the legs of each element being self-aligning, relative to the adjacent preceding element. A su...

A stabiliser tool for connection in a drill string having a fluted stabilising portion comprising a body part (16) integral with the shank (10) of the tool and a leading end sleeve part or cap (18) removably secured to the shank. The cap (18) can readily by replaced when worn. The tool may be suppled as a set including different interchangeable caps having for example, spiral flutes (22) for norma...

Disclosed in the present application is a method of curing a dental impression material by passing actinic light through a tray while the tray is in contact with the impression making composition, a new dental impression composition that is polymerizable by having an initiator activated by actinic light within the visible light range of 360 to 600 nanometers, a new composition of matter that is a ...

PURPOSE:To compensate various aberrations excellent over the whole power variation range of a zoom lens which has two positive and negative lens groups by composing the 1st positive lens of three lens elements and setting specific conditions. CONSTITUTION:The small-sized zoom lens has the 1st positive lens group and the 2nd negative lens group and the power is varied by varying the gap between bot...

PURPOSE:To improve life characteristics by providing one part of the outer circumferential region of a fine solder group connecting a metallic layer carried to a semiconductor base body and a metallic layer carried to a dielectric substrate with a means controlling the shape of the fine solder group. CONSTITUTION:A metallic region 111 is brought into contact with a metallic layer 16a at a step whe...

PURPOSE:To reduce the feeding and preparing time for flank fabric films by fitting simultaneously a plurality of blank fabric films same width or different width. CONSTITUTION:The blank fabric films fitted into a blank fabric film feeder may be a plurality of films in arbitrary number. The specified film from a plurality of blank fabric films having been fitted is transferred to a specified positi...

This invention discloses a thermal head having a resistive layer of a thin Ta-Si-O film containing more than 45 mol % and at most 75 mol % of a silicon oxide in terms of SiO2, and a method of manufacturing a thermal head by sputtering a sintered target in vacuum atmosphere at an argon gas partial pressure of 10x10-3 Torr to 80x10-3 Torr so as to obtain the resistive layer.

PURPOSE:To form a coated layer having the impact strength resistance, the wear resistance and the corrosion resistance on the surface of a metallic or ceramic base material by applying a hot-hydrostatic compression method on a sprayed coated layer which is formed on the surface of the metallic or ceramic base metal to make it dense and vanishing a pore. CONSTITUTION:The surface of a metallic base ...

A knockdown platform or storage bed employs single or double rows of U-shaped channel members to join laterally opposed sideboards, through a detachable coupling at opposed ends of the channel members, to receivers fixed to the inside of the sideboards at longitudinally spaced positions and at both ends. The channel members are provided with C-shaped slots to each side slidably receiving insertabl...

PURPOSE:To attain immediate diagnostic decision by executing sampling and analytical processing always continuously and sequentially updating the analytical data on the basis of moving average or the like. CONSTITUTION:A diagnosing device consists of an arithmetic and control unit 1, a storage device, a conversational input device 3, and a display device 4 similarly to an ordinary constitution. Th...

PURPOSE:To reduce the moment of inertia by fixing and mounting a coil body for a linear motor and fitting a magnet body to a tool arm. CONSTITUTION:When a capillary 16 reaches the upper surface of a pellet 47, the change of a positional signal is detected by an algorithm 50, a changeover circuit 51 is changed over, an algorithm 49 and a comparison circuit 43 are connected while the algorithm 49 is...

A tape cassette has a housing, at least one tape reel, a front wall and a pressure spring for exerting a spring force on the tape reel(s). The pressure spring is held, e.g. jammed or wedged, between the front wall and a connecting pin connecting parts of the housing together by means of anchoring means forming part of the spring itself.
