Abstract: According to the prior art, it is known to connect tagboards (10) of loadspeakers to the loudspeaker frame by riveting. It is also known to strain-relieve connecting cables, which are connected to the tagboard (10) and a signal source, at the loudspeaker. According to the prior art, this is mostly achieved in such a manner that the connecting cable is pressed against the magnet system of the loudspeaker by means of a so-called cable tie. It is also known to clamp in the connecting cable between a lug formed at the loudspeaker frame (12). To simplify production, it is specified to provide the tagboard (10) with locking hooks (13) which securely hold the tagboard (10) at the loudspeaker frame (12) after it has been connected to the web (11). The strain relief for the connecting cable (22) is achieved in such a manner that a locking latch (18) can be inserted into openings (16) of the tagboard (10). Once the locking latch (18) has found its final position on the tagboard (10), the locking latch (18) interlocks with the tagboard (10). The shaping of tagboard (10) and locking latch (18) matches in such a manner that, when the locking latch (18) has found its final position, a connecting cable (22) inserted between these two components is clamped in. This achieves effective strain relief in the area of the tagboard (10). <IMAGE>

Abstract: A pay out system for paying out a flexible elongated element such as a filament, connecting a first object such as an air vehicle (2), to a second object such as a launcher (4), includes a bobbin (8) carried by the first object and having a first flexible elongated element (6) wound therearound one end of which is connected to the first object and the opposite end of which is connected to the second object by a second flexible elongated element (6) wound in loop form on a second bobbin (10) adjacent to the second object. A tension sensor senses the tension in the second flexible elongated element.

Abstract: An optically-amplifying repeater includes a monitor and control portion (9,9') for outputting a response signal in response to a supervisory control signal, a pair of erbium-doped fibers (1,1') for optically amplifying an input optical signal by stimulating action of a pumping laser diode (6,6') and outputting the amplified optical signal, a pair of optical output stabilization portions (5,5') for outputting a DC current I DC  driving the pumping laser diode such that the optical output level of the erbium-doped fiber becomes constant, and a pair of amplification portions (7,7') supplied with the response signal output from the monitor and control portion (9,9') for outputting an AC current I AC  driving the pumping laser diode. The repeater further includes a pair of gain control portions (13,13') for outputting a control signal V CONT  controlling the gain of each of the amplification portions (7,7') such that the DC current I DC  and the AC current I AC  satisfy the relationship I AC  = a x I DC  + b (a, b: constants). With such arrangement, the main signal and the response signal are amplified at the same rate and, hence, the index of modulation of the response signal component relative to the main signal can be kept virtually constant even when there is produced a change in the input signal level to the optical amplifying repeater, the temperature of the same, and the like.

Abstract: A flaw detection system that can detect not only bubbles, stones and knots but also flaws, such as cords and reams, that are subject to less optical changes in transmitted light is provided. A glass plate (10) travelling in a manufacturing line is scanned with a beam spot (26) in the direction orthogonally intersecting the manufacturing line. The light transmitted through the glass plate (10) is received by an optical-fiber array (32) arranged in a direction orthogonally intersecting the line. Optical fibers (34) in the optical-fiber array are connected cyclically to a plurality of photomultipliers (PM1-PM10), which convert the light received by the optical fibers into electrical signals (SG1-SG10). Flaw signals are produced by extracting flaw information signals (TH+, TH-, MASK) from these electrical signals in an analog processing section (44), and masking them in a masking section (46). Positional information indicating flaw patterns and positions is produced from these flaw signals.

IPC: H03K17/08
Filed: 1993-05-27
Abstract: A particular electrostatic discharge (ESD) protection problem is faced when only n-channel output transistors (e.g., 201, 202) are present, since there is no p-n junction that could serve to clamp positive ESD voltages, as would be the case if a p-channel output transistor were present. In the present technique, the output transistor itself is used to conduct the ESD current to a power supply conductor (V SS ). To assist in the turn-on of the n-channel output transistor, a transistor (e.g., 208) couples the bond pad (e.g., 200) to the n-tub (e.g., 213) in which the p-channel pre-driver transistor (e.g., 210) is formed. Conduction through this transistor raises the n-tub voltage when an ESD event occurs, thereby preventing the p-n junction of the p-channel pre-driver transistor from clamping the turn-on voltage, which would limit the protection obtained by this technique. This technique is especially valuable for SCSI (Small Computer System Interface) chips, since only n-channel output transistors are used. It may also be used in TTL-output buffers, which also use n-channel pull-up and pull-down devices. P-channel devices may be comparably protected.

Title: Magnetic driving mechanism for a pump having a flushing and cooling arrangement
Inventor: GERGETS PAUL
IPC: F04C15/00
Filed: 1993-08-17
Abstract: A magnetic drive mechanism and cooling system for driving a rotary pump having a magnetic rotary drive member with a recess therein. A magnetic rotary driven member is located in the recess of the drive member. A container is located between the drive member and the driven member for preventing the escape of cooling fluids circulated therein. Inlet and outlet fluid passages extend through the housing of the drive mechanism to the fluid containment area. Another fluid passage extends from the fluid containment area into the chamber of the pump. A cooling fluid is pumped through the fluid passages at a higher pressure than the pressure of the pumped fluid within the pump to prevent flow of the pumped fluid into the fluid passages and containment area of the drive mechanism to avoid contamination thereof while the cooling fluid is circulated to cool the driven member.
