Abstract: A tool is constructed by a plurality of diamond columns 22 arranged so as to protrude from a working surface and a conductive bond member 24 for integrally fixing the diamond columns. The conductive bond member is electrolytically dressed while a conductive liquid is supplied between the bond member and an electrode 4 which faces the bond member at a distance, thereby enabling the diamond columns 22 to protrude. By this construction, the tool can be applied to both an efficient rough cutting for a ductile material and a precise grinding for a brittle material without detaching or re-attaching a workpiece, the relatively soft ductile material such as aluminum, copper, or plastic can be worked with a deep cut, the brittle material such as monocrystal silicon, glass, or tungsten carbide can be efficiently and stably ground, so that a fluctuation of a working position due to wear can be compensated.

Abstract: Super clean air having therein chemical components—such as hydrocarbons, organic halogens, acidic gases, basic gases, aldehydes, nitrogen oxides, and H2O (that is, all components other than oxygen, nitrogen, and noble gases—the types of chemical components differ depending on the source of the air)—in concentrations no more than 1 ppb and a dew point lower than −40° C., is obtained from the atmosphere by low-temperature adsorption treatment in stages at temperatures ranging from −40° C. to −180° C. Material air collected from the atmosphere is pretreated in a room-temperature adsorption step to remove moisture and carbon dioxide. The pretreated air is then low-temperature adsorption treated by absorbents in a plurality of steps to adsorb the gaseous chemical components, the treatment temperature being lower in each succeeding step. Treatment at −40° C. may remove, for example, HF, SO2, and/or NH3. Treatment at −100° C.

Abstract: Light wave diffraction device formed of a dielectric layer (4), a reflecting structure (12) arranged on one lower face (10) of said layer, and a diffraction grating (8) arranged on one face (6) of said layer. The height (H) of the layer is selected so as to substantially satisfy the resonance condition for a leaky mode in said layer for at least one given incident wave having a wavelength &lgr; and a determined angle of incidence. Next, the diffraction grating has a spatial period selected so that the incident wave is diffracted essentially along the first negative diffraction order and at an angle of diffraction different to the angle of incidence (outside the Littrow condition). In particular, the invention provides that either the angle of incidence, or the angle of diffraction is high, i.e. relatively close to 90° from the direction perpendicular to the diffraction grating.

Abstract: A baler (10) for wrapping a rotating bale (52) of crop material (26) with strands of twine (72) has two twine tubes (68) through which the twine is fed so that ends of the strands dangle from the tubes. A bale density sensor (36) senses bale density and a controller (42) compares the sensed density with a desired density selected by an operator via an operator control panel (34). When the sensed density reaches about half the desired density the twine tubes are moved to a twine insert position so that the ends of the strands dangle adjacent the rotating bale. When a full bale has been formed, a duckbill (60) is actuated to push the ends of the strands toward the bale where they are caught up in the crop material. If either strand is not caught up in the rotating bale, the operator may abort the wrap cycle and initiate a new wrap cycle by pressing a wrap key on the control panel.

Abstract: An ejection device 1 for the high-pressure ejection of a liquid or a liquid containing solid particles, comprising a pressure chamber 13 to accommodate the liquid therein, which opens into an ejection opening 11 and is delimited by a working piston 5. The working piston 5 is, upon application of an elastic impact on its end facing away from the pressure chamber 13, capable of transmitting a compression wave which may displace the pressure chamber-facing end of the working piston 5 by a predetermined displacement stroke into the pressure chamber 13 so that the volume thereof is reduced. The reduction in volume of the pressure chamber 13 is signicantly smaller than the volume of the pressure chamber 13.
