Abstract: An electrical charging system (17) for repeatedly electrically charging a photoconductor layer (16) on an electrical conductor through charging that photoconductor layer (16), selectively discharging it, providing toner thereon, and removing the charge image in the photoconductor (16) for each of as many toners as desired for forming a final printed image, followed by using a removal radiation of a shorter wavelength on the photoconductor (16) to avoid long term changes therein. A further charging cycle may be used before the next printed image operation begins.

Abstract: A method of fabricating a semiconductor laser device includes disposing a lower cladding layer (22), a superlattice active layer (23), an upper cladding layer (24), and a contact layer (25) in the named order on a substrate (21), disposing, on resonator end surfaces, films (26A,26B) containing a material which can cause disorder of the semiconductor superlattice structure at a high temperature, and causing current to flow between the substrate (21) and the contact layer (25) to cause laser oscillations. The laser oscillations cause laser light to be generated, which is absorbed at the resonator end surfaces (28A,28B). The resonator end surfaces (28A,28B) are locally heated due to absorption of laser light, whereby the disorder-causing material is diffused into the resonator end surfaces and the semiconductor superlattice structure in the vicinity of the resonant end surface is disordered to thereby form window regions (27A,27B).

Abstract: In a reproducing operation, scanning information is detected while scanning an information string with a probe (1) such that a density of the scan lines (A₁,B₁,C₁,D₁,E₁,F₁) is higher than a density of the recorded information, and a logical-sum signal of the plurality of scanning information is used as a reproduced signal.

Abstract: When printing on plastic products, it is necessary first to subject their surface to a high-energy pretreatment. This procedure increases the surface energy of the plastic part and thus the adhesive strength of the ink. A typical example is the application of a corona discharge to a web (3). In order to control the output of the corona generator and thus the strength of the pretreatment, the surface energy of the web (3) running out (3) must be checked constantly. Hitherto this has been done manually, using so-called test inks, which is laborious and does not permit automatic control of the corona generator. The core of the present invention is the determination of the surface energy of a web (3) by virtue of its adhesive strength. In one embodiment, the web (3) is passed over two rollers (1, 2), and the deviation of its course (8) from the common tangent (7), generated by adhesion to the first roller (1), is evaluated. Evaluation is effected, for example, by reflection of a laser beam (13). In a further embodiment, the web (3) is passed over a braked roller (1), and the torque transmission from the web (3) to this roller (1) is measured. In a third embodiment, a tab (19) slides on the web (3), the sliding-friction force being measured. In all cases, the primary signal can be processed by incorporating various process parameters, and then serves as a value for the surface energy of the web (3), by means of which, for example, a corona generator can be controlled. <IMAGE>

Abstract: A method is disclosed for terminating a coaxial connector (10) to a coaxial cable (12).

The signal wire is then electrically and mechanically bonded to an exposed portion of the signal pin within the rear portion of the shield member while the signal pin is held by the shield member. The rear portion of the shield member is then closed around the bonded portions of the signal wire and the ground means.

Abstract: A television system includes a picture tube beam current limiting arrangement which operates to reduce image contrast without affecting image brightness when the beam current exceeds a first threshold. However, if the user brightness control setting exceed the nominal (midrange) brightness control level, the image brightness is reduced when the beam current exceeds a second threshold which may be equal to or greater than the first. The image brightness is reduced only until the image brightness is within a small margin of the nominal image brightness level. Any further beam current limiting, for example to account for abnormal operating conditions of the television system, is accomplished by further brightness reductions.

Abstract: A marine propeller includes a hub rotatable about a longitudinal axis and having a plurality of blades extending radially outwardly therefrom and pivotable about respective radial pivot axes between a low pitch position and a high pitch position. Each blade has a hydrodynamic force characteristic which shifts the location of the resultant hydrodynamic force on the blade in a direction aiding up-pitching of the blade, and increasing the up-pitching pivot moment with decreasing angles of attack. A counteractive hydrodynamic force generating area is provided on the negative pressure backside surface of the blade and shifts the location of the resultant hydrodynamic force on the frontside surface forwardly with decreasing angle of attack. The blade is pivoted by increased water flow along the counteractive hydrodynamic force generating area with decreasing angles of attack, which increased water flow generates a backside hydrodynamic force on the blade at the counteractive hydrodynamic force generating area spaced from the pivot axis by a moment arm provided by the section of the blade between the pivot axis and the counteractive hydrodynamic force generating area, such that the backside hydrodynamic force acting on the moment arm pivots the blade to an increased pitch position. The counteractive hydrodynamic force generating area on the backside surface at the rearward trailing portion separates water flow along the backside surface at high angles of attack, and re-attaches water flow along the backside surface at low angles of attack to change the backside surface at the rearward trailing portion to a positive pressure area to generate the up-pitching moment. A disc has a plurality of guide slots each receiving and retaining a respective lever arm extending rearwardly within the hub from a respective blade. A biasing spring coaxial with the longitudinal axis of rotation of the hub biases the disc to in turn bias the lever arms and blades to the low pitch position. The disc is a generally flat planar plate-like member extending radially outwardly from the longitudinal axis at the rear of the hub and includes a preload mechanism accessible at the rear of the hub for adjusting the bias. The disc restricts movement of the lever arms along the guide slots such that the lever arms can move only in unison, which prevents blade flutter. Pivoting of the blades is controlled by both a) movement of the lever arms along the guide slots, and b) arcuate movement of the guide slots as the disc rotates about the longitudinal axis, such that pivoting of each blade from its low pitch position to its high pitch position requires both a) movement of the respective lever arm along its respective guide slot, and b) rotation of the disc to arcuately move the guide slot.

Abstract: A regenerative digital communication channel extender (136,137) is provided which converts electrical signals in a first communication network (101) into optical signals and then reconverts the optical signals back into electrical signals for application to a second communication network (102). The conversion is preferably performed using state machines. The communication in the first and second communication networks are preferably in a first protocol, whereas the optical communication is in a second protocol. The state machines convert the communications from the first protocol to the second protocol, and back from the second protocol into the first protocol. In the process, the communication in the first communication network is faithfully regenerated in the second communication network. In addition, a unique phase lock circuit is contemplated which requires only one pulse of an incoming digital communication to synchronize a local clock.
