Inventor: TAKEHISA INOUE C O TORAY INDUS
IPC: F16K11/074
Filed: 1983-01-31
Abstract: The present invention relates to a rotary valve for distributing a fluid in various directions and collecting fluids from various directions. The rotary valve consists of two stator disks having passages that constitute a part of complete passages through which the fluid runs, and a rotor disposed between the two stator disks and having passages which communicate with selected at least two of the passages in the stator disks to form complete passages through which the fluid runs. Each time the rotor is turned intermittently, different passages are formed through which the fluid runs.

Abstract: A method of fabricating a CMOS device is provided for patterning the gates and protecting them during ion implantation. 
     A metal layer (20) is sandwiched between the gate material layer (18) and the photoresist layer (22) that is used as a pattern mask for the gate material during etching. The photoresist pattern (22) masks the metal as it is etched, and the metal pattern (20M) masks the gate material as it is etched to form a gate pattern. The metal mask is left over the gates to serve as an ion implant stop mask. Two photoresist patterns are successively formed to cover the devices of one conductivity type while the opposite type device source and drain regions are implanted. 
     Then, the metal mask may be easily stripped without causing damage.

Abstract: Die Erfindung betrifft ein Verfahren zur fließenden Anlage von Bögen, die über einen Anlegetisch, schuppenförmig versetzt, einer Ausrichtvorrichtung zugeführt und nach dem Ausrichtvorgang an die bogenverarbeitende Maschine abgegeben werden. Die Bögen behalten während dieser Ausrichtung ihre Bewegung in Richtung auf die bogenverarbeitende Maschine bei. Das Verfahren besteht aus folgenden Schritten: Zunächst erfolgt die Vorderkantenausrichtung durch ein synchron zur bogenverarbeitenden maschine bewegtes Maschinenteil mit Vordenmarken, danach wird die Seitenkantenausrichtung durchgeführt und schließlich hält, bzw. transportiert die Ausrichtvorrichtung den ausgerichteten Bogen in seiner Soll-Lage solange, bis die passerhaltige Übernahme des Bogens von einem weiterfördernden Transportorgan gewährleistet ist. Die ausrichtung der Bögen auf dem Anlegetisch erfolgt somit ohne Stillstand.

Abstract: At its free end, a machine-tool spindle has a cylindrical locating bore (3) and an annular end face (4) surrounding the locating bore and running perpendicularly to the spindle axis (S-S). A toolholder (9) which can be inserted into the spindle has a cylindrical shank (10) fitting exactly into the locating bore (3) and an annular surface (13) surrounding this shank (10) and running perpendicularly to the shank axis. In the area of the cylindrical locating bore (3), the spindle (1) is provided with two diametrically opposite, radially running internal threads (5, 6) into which one clamping screw (7, 8) each provided with a conical extension (7a) or a conical recess (7b) can be screwed.

Title: Alphanumeric keyboard
Inventor: TSIKOS CONSTANTINE J
IPC: G06F3/023
Filed: 1984-09-20
Abstract: A simple, low-cost alphanumeric keyboard contains, in the sequence from its lower side to its upper side, (a) a base, which is a non-conductive supporting surface (24) directed upwards, (b) a conductive strip (26), which is arranged on the supporting surface (24) and (c) a flexible layer (56), which is arranged above the conductive strip (26). The conductive strip (26) is preferably formed as a continuous strip of a material coated with an electrical resistor, having an essentially uniform, constant resistance per unit length. The flexible layer (56), which is arranged above the conductive strip (26), has a conductive surface which is directed downwards, in the direction of the conductive strip (26). The flexible layer (56) is attached in a manner such that it is normally not in contact with the conductive strip (26) but can manually be pressed down in the direction of the conductive strip (26), in order to make contact with the conductive strip (26) at individual points which are allocated to the respective alphanumeric characters (18). The conductive strip (26) and the flexible layer (56) thus form a voltage divider which generates a specific voltage as a function of the point of contact between the conductive strip (26) and the flexible layer (56). This voltage is applied to an A/D converter (34), which forms a digital signal. <IMAGE>

Abstract: A novel device for mass transfer across a membrane is disclosed, which is particularly suitable for use as a blood oxygenator. The novel device is of the type having a pleated, selectively permeable membrane defining first and second sets of alternating pockets for the flow of a fluid to be treated (e.g. blood) and a treating fluid (e.g. oxygen), and a discrete support screen disposed within each of the pockets of said first and second sets. Of considerable importance is the feature that the support screens are designed to be substantially interdigitated when the assembly of membrane and support screens is held as a compressed stack within the housing of the device. The novel mass transfer apparatus may be utilized as a compact blood oxygenator with excellent gas transfer rates, low pressure drops and negligible trauma to blood components.

Abstract: A font recall system stores a font of alphanumeric characters in a video display format for selective insertion as a caption into a video image. Characters are stored on a video disk (22) in digital pixel form with full dynamic resolution. Low pass filtering is employed to preserve high image quality and eliminate jagged edge aliasing at character boundaries. A first frame store (32) receives selected characters from the video disk through an image size reducer (46) to store the characters at selected display positions with a selected size to form a caption under control of a central processing unit. A keyer receives the caption video data from the first frame store as well as a background image to form a composite image, which is stored in a second frame store (34) before being output as a continuous television video signal.

Abstract: To generate an image, at least two transparent single images (12,13) are arranged behind one another, in which the transparencies of the individual picture elements (21-25) are selected in such a manner that the mean value of the products of the transparencies of picture elements in each case located behind one another in the direction of viewing, over a number of adjacent picture elements, result in the transparency of the image to be generated. In this connection, the two single images can be completely independent of one another and of the image to be generated, which merely results in a certain restriction in the range of the transparency values. If the two single images are arranged at a certain distance behind one another, stereoscopic images can also be generated in this manner. In this case, in particular, the two single images can also be generated by LCD displays (12,13) which rotate the polarisation of the passing light (18a,18b,18c). …<IMAGE>…
