Abstract: A device having a slidable body (4) driven by a synchronous-type electric motor (3), wherein a cylindrical drum (10) is secured to the output shaft (11) of the motor, a leaf spring (12) is provided between the drum periphery and the slidable body (4), and the position control of the slidable body is performed by counting the frequency of the power circuit is disclosed. The output shaft of the motor has a specific rotating speed or angle relative to the frequency of the power source. Therefore, the sliding body has a specific amount of axial reciprocating movement depending on the direction of the rotation of the output shaft of the motor. It is, therefore, possible to determine the actual position of the sliding body by counting the frequency of the power source simultaneously with the rotation of the output shaft of the motor. Because the drum (10) which connects the slidable body (4) by means of the leaf spring (12) is precision cylindrical, the leaf spring on the surface of the drum converts the rotation of the output shaft (11) of the motor (3) accurately to the axial movement of the sliding body.

Abstract: A starburst processor (20) for use with a system having a means (16) for generating graphic data for logical pixels to be displayed on a display (14) having physical pixels receives commanded intensity values which have one-to-one correspondence with logical pixels. The starburst processor (20) provides actual intensity values which have a one-to-one correspondence with physical pixels, each actual intensity value I ij  being a function of commanded intensity values for a predetermined group of neighbouring logical pixels including a selected logical pixel corresponding to the physical pixel to receive the actual intensity value. This actual intensity value I ij  is assigned a value from a predetermined plurality of different values stored in a PROM (66) addressed by three intermediate read out from another PROM (56) addressed by three adjacent, vertically aligned commanded intensity values made coincident by timing and delay circuitry (36,38,40,42,44,46,48,50,52,54) interposed between an input (34) for a sequence of commanded intensity values and the first PROM (56).

Abstract: A method for "on-line/off-line" digital signing is described and begins by pre-computing a data string x from a pair of matching public and secret keys of a digital signature scheme such that, for any message m later selected to be signed, a signature of m derived from x can be computed substantially faster than the signature of m derived from the matching public and secret keys. After a message m is selected to be signed, the method computes a signature a of the message m using the data string x. Because the method uses a two-stage approach to sign a message, the technique can be advantageously used to enhance the security of known digital signature schemes or to effect transaction processing using "smart" cards.

Abstract: A method for increasing the width of a transistor includes first forming a nitride cap (14) over the substrate (10) and then forming trenches (24) and (26) on either side of the cap (14) and having tapered sidewalls (28) and (30). A conformal layer of nitride (32) is formed over the substrate and then anisotropically etched to form sidewall layers (34) and (36). Field oxide is grown in the trenches with birds beaks (42) and (44) extending upward under the sidewall layers (34) and (36). A portion of the sidewalls (28) and (30) of the trenches remain such that the overall surface area between the edges of the birds beaks (42) and (44) is increased. A layer of strip oxide is then grown on the substrate to provide rounded edges (47) and (49). The strip oxide is then removed by a fifty percent over etch to cause the birds beaks (42) and (44) to recede, thus further increasing the surface area. The gate electrode of a transistor (54) can then be disposed thereacross, thus increasing the width of the transistor for a given silicon surface area in the initial material.

Abstract: The system according to the invention is used for providing the possibility for bidirectional transmission of telephone and data signals between a central station and subscribers in the subscriber line area. In the central station (100), a frequency-division multiplex signal is formed which contains the subscriber-individual telephone and data signals for a group of subscribers (111). This frequency-division multiplex signal is transmitted from the central station via an optical waveguide (112) common to the group of subscribers to the vicinity of the subscribers where it is optically distributed and transmitted to the subscribers via subscriber- individual optical waveguides (L1 to Lk). Subscriber-individual carrier frequencies are used for the subscriber-individual signals. From the subscribers (111) to the central station, the subscriber- individual telephone and data signals are transmitted via the same optical waveguide (112, L1 to Lk) with the same wavelengths but subscriber-individual carrier frequencies. <IMAGE>

Abstract: An improved needle device for infusion of the type including a liquid delivering passage and an air introducing passage extending in parallel with each other is disclosed. The needle device comprises a tubular needle (1), a bottom portion (6) into which the rear part of the tubular needle is immovably fitted, a flange portion (9) made integral with the bottom portion, a cover member (4) airtightly secured to the flange portion and a valve disc (8) received beneath a circular projection on the flange-shaped part of the cover member. As air enters through an air inlet port (10) on the flange portion, the valve disc is raised up so that air is introduced into the interior of a parenteral liquid container via a cutout on the circular projection, a clearance between the bottom portion and the cover member and an annular clearance between the tapered foremost end of the cover member and the tubular needle. When liquid in the container flows out through the air inlet port, the valve disc comes in the inside wall surface of the flange portion under the effect of dead weight of the liquid itself to close the air inlet port with the valve disc.

Abstract: In a known magnetic videotape device for the transparent recording of a baseband television signal, a non-linear preemphasis is carried out at the recording end and a non-linear deemphasis is carried out at the replay end for improving the signal/noise ratio. The novel magnetic videotape device should also be suitable for the transparent recording of composite colour television signals and at the same time ensure a good signal/noise ratio. Essentially, this is achieved by automatically switching between a non-linear and a linear preemphasis of the higher-frequency signal components during the recording and deemphasis during the replaying. The non-linear part of the preemphasis and of the deemphasis, respectively, is only effective in the presence of baseband television signals. In the case of composite colour television signals, a linear preemphasis and deemphasis is carried out exclusively. Magnetic videotape devices by means of which both satellite television signals and composite colour television signals can be recorded. <IMAGE>
