Title: Connection of a tap or fitting connection piece with a conduit, tap or fitting for the connection and method of manufacturing the connection and the tap or the fitting
IPC: F16L13/16
Filed: 1989-04-27
Abstract: Press connection of a connection piece of a tap (1) or of a fitting of cast metal to a conduit (5) whose crushing yield point and modulus of elasticity are greater than those of the connection piece (2). The wall thickness of the piece (2) is so dimensioned that it can be pressed onto an elastic conduit (5) adapted to its internal diameter. Since, for example, in the case of a plastic or copper conduit the crushing yield point and the modulus of elasticity of the conduit are smaller than those of the piece (2), an elastic support sleeve is pushed into the pipe, its crushing yield point and modulus of elasticity being greater than those of the piece (2), pressing the plastic conduit sealingly against the piece (2). <IMAGE>

Title: Process for fabricating superconducting ceramic materials
IPC: C04B35/00
Filed: 1989-05-31
Abstract: A R-A-Cu-O based superconducting ceramic is

Subsequently, the molded body is sintered in an oxygen 
atmosphere, at a predetermined temperature for a 
predetermined retention time to thereby obtain a 
sintered molded body or a ceramic. Then, the ceramic is 
cooled at a cooling rate satisfying a relation expressed 
by the equation:    
 
 = k · T · √ P O₂      
(0.8 ≦ k ≦ 1.0)

molded body during said cooling,  
t indicates cooling period (hours),  
P O₂  indicates the partial pressure of oxygen 
(atm) during cooling  
in a high temperature region at a temperature not lower 
than 300 °C after sintering. The ceramic having high 
critical temperature, high critical current value, and 
critical magnetic field is obtained.

Title: Capacitive incremental position measurement and motion control
IPC: G01D5/245
Filed: 1989-05-17
Abstract: A capacitance based, high resolution, incrementally encoding, position 
measuring system employs an array of identical replicated electrodes that are 
driven in unison from an RF source and mounted in proximity to a patterned 
monolithic reference ground plan of arbitrary size. Motion of such position-­
sensing arrays is monitored by measuring both the sums and the differences of the 
electrode displacement currents in such a way as to provide incrementally 
encoding position signals  in both one and two dimensions  together with a 
continuous measurement of the height of the sensor array above the patterned 
ground plane. In various modifications, the system and methods are applied both 
to one dimensional linear, as well as to two dimensional planar and two 
dimensional cylindrical motion measurement and control. Various techniques for 
eliminating the effects of spurious capacitances are also disclosed.

Patent EP-0384353-A3 (EP)
IPC: G01S17/04
Filed: 1990-02-19
Abstract: A reflective-type photoelectric switch projects emitted light from a light-emitting element toward a detection zone by a light-projecting optical system, and guides reflected light from an object to be detected in the detection zone to a light-receiving element by a light-receiving optical system. A special optical element is used in part of at least one of the two optical systems. The optical element functions to diverge light in a direction parallel to a plane containing the optic axes of the light-emitting and light-receiving elements, and condense light in a direction perpendicular to the same plane. As a result, it is possible to detect, with excellent sensitivity, both an object which is far from the switch and an object very near the switch.

Title: Paper feeding control device
IPC: G03G15/00
Filed: 1990-05-29
Abstract: A paper feeding control device in which paper 
sheets delivered from paper containing sections (12, 13, 
14) are stopped when their front ends are detected by 
paper detecting means (24, 25, 26). The paper sheets are 
subsequently fed from the position where they are 
stopped. The subsequent paper sheet is delivered at 
intervals of time (tl) corresponding to a minimum 
required spacing between paper sheets. Accordingly, even 
if the spacing between paper sheets is decreased to a 
desired spacing or less by slip of the paper sheets 
during feeding, the paper sheets do not collide with each 
other and the paper jam or the like does not occur. In 
another embodiment, in continuously feeding paper sheets, 
two conditions, that is, the elapse of time (t2) 
corresponding to the ideal spacing with which paper 
sheets are fed and the elapse of time (tl) corresponding 
to the required minimum spacing between paper sheets are 
ANDed, to control the timing of starting to feed the 
subsequent paper sheet. The paper sheets continuously 
conveyed are always suitably spaced apart from each 
other. Accordingly, even if the ends of the paper sheets 
are out of line with each other in a paper containing 
section (12, 13, 14) and the paper sheets are delivered 
 
 
slightly earlier or later at the time of starting to feed 
the paper sheets or the paper sheets slip while being fed 
or conveyed, there occurs no paper jam or the like on a 
conveying path.

Title: Method and apparatus for storing imbricated sheets upon a pallet
IPC: B65H33/04
Filed: 1992-05-06
Abstract: Imbricated or overlapped copies of printed material (10) are formed within a plurality of rows (8) to form a single layer (4) of a multi-layered and cubic-shaped stack (1). The stack (1) allows for more efficient use of space within the storage of printed materials (10), and allows for easier and faster storing and retrieving of the printed materials (10). The apparatus for forming the stack (1) includes a plurality of in-feed conveyors (22) which feed imbricated copy stream segments (8) to a shuttle assembly (41) upon a plurality of side-by-side rows. Once filled, the shuttle assembly (41) is positioned over a flat separator sheet (6) and drops the plurality of rows (8) onto the separator sheet (6), thereby forming a single layer (4). The layer (4) is formed directly upon a stack (1) which is formed upon a pallet (2). The separator sheet (6) of the formed layer (4) is supported by the copy streams (8) which lie below on the preceding separator sheet (6). The resulting stack (1) is cubic-shaped and includes a plurality of layers (4) of a plurality of side-by-side rows of relatively flat and horizontal imbricated copy streams (8) that run the full width of the pallet (2). A method of retrieving the copy streams (8) from the stack (1) to the conveyors (23,24) uses the same apparatus for forming the stack (1) and is substantially the reverse of the method of forming the stack (1).
