IPC: G11B5/53
Filed: 1988-01-22
Abstract: 1. Recorder for a matrix-like recording. 2.1. In a matrix-like recording according to German Offenlegungsschrift 3,509,584 with two track lanes on two tape halves (H1, H2) and two groups (K1, K2) of heads, a perfect simultaneous sensing of the track lanes is not guaranteed because of tolerances. A head drum (8) which allows a perfect simultaneous sensing of the two track lanes will be provided. 2.2. This is achieved in that two groups (K1, K2) of heads are provided offset in the axial direction (31) on the head drum (8), and one group (K2) is mounted adjustably in the axial direction (31) by means of an electromechanical actuator (A). 2.3. The recorder is especially suitable for two correlated digital video or audio signals, for example a television signal and an additional signal for HDTV.

Abstract: A system for measuring a chromatic dispersion of an optical fiber based on a baseband phase comparison method has an optical signal transmitter (20), a reference optical fiber (61), a measurement optical fiber (62), and an optical signal receiver (40). The transmitter has  n  light sources (25) for selectively generating, as measurement optical signals, optical signals having wavelengths corresponding to  n  wavelength points to be measured. One of the  n  light sources (25) also serves to generate a reference optical signal. The transmitter (20) further has an optical switch (26 and 27). The optical switch (26 and 27) has  n  optical signal inputs arranged in correspondence with the  n  light sources (25), a measurement optical signal output, and a reference optical signal output. The optical switch (26) commonly outputs, to the measurement optical signal output, the measurement optical signal which is output from the designated one of the  n  light sources (25) and is selectively input to the  n  optical signal inputs. The optical switch (27), which is a half mirror (27), is provided for outputting the reference optical signal generated by one of the  n  light sources (25) to the reference signal output. The optical signal receiver (40) is coupled to the reference optical fiber (61) and the measurement optical fiber (62), and receives the reference optical signal from the reference optical fiber (61) and the measurement optical signal from the measurement optical fiber (62), respectively, for measuring chromatic dispersion. The receiver (40) includes a plurality of programmable optical attenuators (41 and 42).

Abstract: A hand-held pneumatically-powered breakstem rivet placing tool comprises a pulling head (12) driven by a pneumatic piston and cylinder device (13). The drive is transmitted by means of a chain (15), one end (45) of which is secured to the body (11) of the tool and the other end (49) of which is secured to the piston rod (35) of the pneumatic device. Between its two ends the chain forms a loop which passes over a roller (52) which is connected to the pulling head (12) by means of a link mechanism (54, 58). When the pneumatic device (13) is actuated, the movable end (49) of the chain is pulled down, thus pulling the roller (52) and driving the head (12) to place a rivet. The roller (52) is carried on the top of a plunger (56) which is continuously urged upwards by air pressure in the cylinder (63) in which it slides, thereby to return the mechanism to its original position after a rivet has been placed.

Abstract: For monitoring the press loads of the upper and lower punches, which work in pairs, in a tablet press, with which a mean value formed from successive measuring results is compared with two adjustable tolerance limits (G), the mean value (A) is assigned two adjustable individual value limits (B, C) in the case of known methods, by means of which limits the maxima of the individual values of the press loads are compared. However, such an apparatus and this method cannot be used satisfactorily for recognising certain causes of operational disturbances in good time, since, for example, slight damage to an individual punch does not substantially alter the mean value. In addition, the tolerance range must be chosen to be comparatively wide in order to prevent a frequent standstill of the tablet press without particular operational disturbances being present. In order to remedy this, it is provided according to the invention to assign the individual pairs of punches (1,2,3) so-called punch-pair mean value limits (Su, So) by means of which the particular punch-pair mean value (S) is compared, preferably via a connected computer. …<IMAGE>…

Abstract: A magnetic field enhanced vacuum single wafer plasma etch reactor (60) is disclosed. The features of the reactor include an electrically-controlled stepped magnetic field for providing high rate uniform etching at high pressures; temperature controlled reactor surfaces including heated anode surfaces (66 I, 67 I) (walls and gas manifold) and a cooled wafer supporting cathode (72) and a unitary wafer exchange mechanism comprising wafer lift pins (79) which extend through the pedestal (72) and a wafer clamp ring (78). The lift pins (79) and clamp ring (78) are moved vertically by a one-axis lift mechanism (140) to accept the wafer (75) from a cooperating external robot blade (76), clamp the wafer (75) to the pedestal (72) and return the wafer (75) to the blade (76). The electrode cooling combines water cooling (170, 172, 174) for the body (128) of the electrode and a thermal conductivity-­enhancing gas parallel-bowed interface between the wafer (75) and electrode (72) for keeping the wafer surface cooled despite the high power densities applied to the electrode. A gas feed-through device (175, 176, 178, 180) applies the cooling gas to the RF powered electrode (72) without breakdown of the gas. Protective coatings/layers (811, 83) of materials such as quartz are provided for surfaces such as the clamp ring (78) and gas manifold (80). The combination of these features provides a wide pressure regime, high etch rate, high throughput single wafer etcher (60) which provides uniformity, directionality and selectivity at high gas pressures, operates cleanly and incorporates in-situ self-cleaning capability.

Abstract: A launcher (10) has an outer conductor (26) and a tapered central contact pin (42) within a bore (28) of the outer conductor (26) and connects a coaxial trans­mission line with a microstrip transmission line (12). When used with a microstrip transmission line (12) having a specific thickness of dielectric substrate (16) it provides matching of both the characteristic impedance and the electro-magnetic field configuration. The launcher (10) may also be used effectively with microstrip trans­mission lines having different substrate thicknesses. An adjustable stop (46) transversely positions the upper surface of the microstrip transmission line (12) relative to the launcher's outer conductor (26) to counteract capacitive discontinuities caused by different subtrate thicknesses. Although such adjustments flex the central contact pin (42) transversely, thus changing the launcher's characteristic impedance, the launcher provides better overall matching between the two types of transmission lines. The contact tip (44) of the pin (42) has a cylind­rical contact surface coaxial with the pin, thus forming a repeatable line contact with the upper conductor (14) of the microstrip transmission line (12) enabling consistent results. The bore (28) of the outer conductor (26) is at an angle with respect to the coaxial transmission line jack (30), allowing the tapered pin (42) to extend coaxially with the jack (30) so that the pin (42) can be drilled and tapped on its center axis, simplifying its mass production.
