Abstract: The invention relates to electrical devices which comprise two planar electrodes and a PTC conductive polymer element. According to the invention, the conductive polymer element has an intermediate portion of increased resistance, resulting from the presence of one or more relatively non-conductive portions within the conductive polymer element, so that when a hot zone is formed in the PTC element, it is located at or near the intermediate portion, away from the electrodes. Particularly useful devices are circuit protection devices, as illustrated in the Figure.

Abstract: A memory device including memory cells each consisting of a single transistor and a single capacitor is disclosed, in which a large number of active regions of clavicle-like shape in a plan configuration surrounded by a field region are arrayed as interlaced with each other. Each active region includes a common source or drain region connected to a data line, and channel regions and capacitor regions on the both sides of the common region. Capacitor electrodes, gate electrodes and data lines are formed from first, second and third polycrystalline silicon layers, respectively. Owing to the above-mentioned novel construction, reduction of a stray capacitance of a data line and increase in a capacitance of a capacitor section can be realized simultaneously with high density circuit integration.

Abstract: Aus dem digitalisierten Bildsignal wird mittels eines digitalen Filters das Farbartsignal abgetrennt und einem steuerbaren Verstärker zugeführt, der aus der Reihenschaltung einer Shift-Stufe und eines Multiplizierers besteht. Beide Stufen werden von einer Steuerschaltung gesteuert, die den auf digitale Weise gewonnenen maximalen Amplitudenwert des Farbsynchronsignals erhält. Abhängig von diesem Amplitudenwert wird das Farbartsignal stellenverschoben und anschließend in einem Multiplizierer mit einem Faktor multipliziert, der beispielsweise zwischen 0,5 und 1 liegt. Auf diese Weise ist der Verstärkungsfaktor in zwei Teilfaktoren zerlegt, von denen der eine eine ganzzahlige Potenz von 2 ist, und damit wird der Multiplizierer sehr viel günstiger ausgenutzt. Der Amplitudenwert des Farbsynchronsignals wird vor dem Verstärker ermittelt, so daß es sich um eine Vorwärtssteuerung handelt, bei der keine der bei geschlossenen Regelschleifen auftretenden Probleme vorhanden sind.

Abstract: A water softener control includes a cell (29) of sampling resin (30) which received periodic samples of water which has passed through a major portion of the softening bed (11). The sampling resin (30) changes volume when it becomes exhausted and the change in volume is employed to initiate regeneration of the softening bed (11). At the start of the regeneration cycle, regenerative fluid is delivered directly to the sampling resin (30) as well as to the softening bed (11). The delivery to the sampling resin (30) is through a control valve (60, 70) which is piloted by pressures at a venturi injector (21) which is used to withdraw regenerative fluid from a brine tank (22). A vacuum operated control valve (75) which is responsive to the closing of an air check valve (25) in the connection between the injector (21) and the brine tank (22) may be employed to positively close the connection from the sampling cell (29) to the injector (21) when the supply of regenerative fluid is exhausted.

Title: A method of fabricating a MOS transistor on a substrate
Inventor: RYDEN WILLIAM D
IPC: H01L29/423
Filed: 1982-12-10
Abstract: The invention relates to fabrication techniques for the construction of MOS transistors to provide source/drain regions (20, 22) which are self-aligned and non-overlapping with respect to their gate electrode (16). The non-over-lapping feature is provided by defining a gate electrode (16) over a substrate (10), forming an implant mask of dielectric (18), for example, on the sides of the gate electrode (16), and implanting a source/drain region (20, 22) such that the implant mask shields a portion of the substrate from implantation to provide a gap between a side edge of the gate electrode (16) and the implanted regions (20, 22). The source/drain region (20, 22) is then heat driven until its side edge is substantially aligned with the edge of the gate electrode (16). Self-aligned source/drain contacts are also provided using the implant mask to isolate the gate electrode from the contacts and interconnects.

Abstract: This method is used to apply a multilayer, high-adhesion and soft-solderable contact metallisation (7) to the highly doped surface of a silicon semiconductor component (1) and preferably finds application in power semiconductor components such as thyristors. The first layer (2) applied is a metal such as nickel which readily forms a silicide with silicon. The second layer (3) is provided by a metal such as chromium whose silicide formation proceeds appreciably more slowly than that of nickel. A metal such as nickel, which is only slightly dissolved by soft solder, follows as third layer (4). The fourth layer (5) applied is a transition layer of nickel and a noble metal and this gradually merges into a fifth layer (6), which is a protective layer of silver. Alternatively, the nickel and chromium of the first and second layer can be applied together. <IMAGE>

The digital filter (22) can track the rotational frequency of the rotating component and can be accurately centred on that frequency. The digital filter includes a pair of memories (82, 88) which respectively store sampled data and constant coefficients. The sampled data storage can accommodate the output of more than one sensor and data from each sensor can be alternately processed.

Abstract: t An injection port for injecting fluid through a needle into the contents of a container. The port has a covering film securing a sterile pad of resealable material to a base member having a portion pierceable by a needle. A tear strip is heat welded to the cover so as to form a removable tab comprised of a welded tear strip section, a welded cover section and an unwelded lap forming a grip for removing the tab. The tab is connected to an unwelded portion of the cover by a tear joint of substantially less tear strength than either the tab or the unwelded cover portion. The cover and the base member define a chamber for maintaining the sterility of the pad until the tab is removed to expose a sterile portion of the pad for insertion of the needle. The base member may be a container wall, a tube communicating with the container interior, a mounting film providing a modular port, or a protector fim preventing contact between the pad and the bag contents. The cover may have a pull tab for removal of the pad. The modular port may be held in position by a pressure sensitive adhesive. A method for making the port is described.

Abstract: A method for isolating from a cell population those cells producing and secreting antibody exhibiting a high binding affinity for a particular antigen. The isolation depends upon the ability of any such antibody to displace from the antigen previously-bound F ab fragments of antibodies exhibiting less binding affinity for the antigen, and then using the F c region of any such displacing antibody as a site for the binding of materials which bring about a selective distinguishable condition which can be used as an indicator of the location of cells in the population which produced and secreted the.displacing antibody.
