Filed: 1988-10-12
Abstract: A method of making a filter body for a filter of the depth layer type comprises helically winding a braid (3) of cellulose-spinbonded nonwoven cloth around a bobbin having many pores and reciprocating in the axial direction while rotating. The braid is thus wound clockwise around the bobbin during the reciprocating movement in one direction and counter-clockwise during the reciprocating movement in the other direction so that intersections occur, and the clockwise wound braids (5-n, 5-n+1) and the counter-clockwise wound braids (6-n, 6-n+1) are successively stacked in aslant relation while partly overlapping each other to form roof-shaped structures. The height of the roof-shaped structures formed in subsequent cycles is progressively increased toward the outer periphery of the filter body so as to establish a distribution in which the space density increases progressively from the outer periphery toward the inner part of the filter body.

Abstract: A grinding machine for grinding epitrochoidal, hypotrochoidal, and circular bearing races in one set-up without having to move the part and to insure near perfect concentricity between all of the bearing races. 
     A machine blank is mounted on an upper rotary table that is in turn mounted on a lower rotary table. The upper table is driven both by the lower table and by an independent servomotor. The net speed of the upper table is the difference between the two driving speeds of the tables. The axis of rotation of the upper table is capable of being offset from the axis of rotation of the lower table. The two tables are rotated in opposite directions while a grinding wheel is moved laterally into contact with the surface of a rough-machined part to form the trochoidal surface. The characteristics are determined by the amount of the offset, the diameter of any rollers that are to be positioned between the trochoidal surfaces in the speed change device, and the relative speeds of the two tables. After the trochoidal surface or surfaces are completed, the lower table is stopped in its home position and the upper table is driven in order to grind the circular bearing race or races. Three independently-driven grinding spindles are provided.

Abstract: An optical switch having two spherical or elliptical corner-reflecting surfaces (5c) provided in a light-conducting member (5, 10), a shutter (8) to open and close a light path between the corner-­reflecting surfaces, and focusing lenses (5b) to focus the incident beam from an emitting optical fiber (3) and to focus the emitting beam from the light-conducting member to a primary receiving optical fiber (4). Because almost all the beam transmitted through the light-conducting member is focused at one point (A) in an air gap (5d) in which the shutter moves, the optical switch can transmit the beam with high efficiency without leakage to the outside, and a small stroke of the shutter is sufficient to completely transmit or stop the beam. In another similar optical switch having a reflecting surface (11a) at the tip of the shutter (8) for inclining the beam, as well as having a secondary receiving optical fiber (12) aligned with the path of the inclined beam, the beam is switched to be transmitted to the primary receiving optical fiber (4) or to the secondary receiving optical fiber (12) according to the position of the shutter. Thus, the ON/OFF state of the optical switch can be indicated, or a transfer-type optical switch can be obtained by using the secondary receiving optical fiber as well as the primary receiving optical fiber as switching circuits.

Abstract: A smart reactivity computer is disclosed that processes signals from multiple neutron detectors to generate regional values of core reactivity that are supplied to a strip chart recorder. When the regional values are coincident for a time duration sufficient to satisfy a statistical fit test to a straight line, the computer alerts the operator and determines control rod worth by first fitting a straight line to the coincident portion of the reactivity values. The computer then determines intersections between the straight line and the reactivity value lines produced when the control rods are moved on both ends of the straight line. The difference between intersections for.a single control rod movement line determines control rod worth for that movement.

Abstract: This invention relates to tThermal dye transfer printing systems which are adapted for multiple-use printing modes wherein one dye transfer sheet is repeatedly used and which comprise a dye transfer sheet having, on a substrate, a dye transfer layer containing a sublimable dye and a binder resin and a dye receiving sheet having a dye receiving layer which has a diffusion rate of the dye smaller than the dye transfer layer. This is effective in suppressing a lowering of printing density owing to the increase in number of printing cycles using one dye transfer sheet. Alternatively, the dye transfer sheet is constituted such that the dye transfer layer is made of a least two sub-layers in which the concentration of the dye decreases from the sub-layer formed directly on the substrate toward the surface side of the dye transfer layer. The dye is invariably supplied from the higher concentration sub-layers to ensure full color printing with a remarkably increasing number of multiple-use printing cycles.
