Abstract: An improved stereolithography system for generating a three-dimensional object by creating a . cross-sectional pattern of the object to be formed at a selected surface of a fluid medium capable of altering its physical state in response to appropriate synergistic stimulation by impinging radiation, particle bombardment or chemical reaction, using information defining the object which is specially tailored to provide built-in supports for the object, reduce curl and distortion, and increase resolution, strength, accuracy, speed and economy of reproduction, the successive adjacent laminae, representing 'corresponding successive adjacent cross-sections of the object, being automatically formed and integrated together to provide a step-wise laminar buildup of the desired object, whereby a three-dimensional object is formed and drawn from a substantially planar surface of the fluid medium during the forming pro- 'cess. Stereolithographic supports for the object are described, including a preferred embodiment known as web supports.

Abstract: This invention concerns alteration of the interaction of PTKs and T-cell receptors. We have found that PTKs and T-cell receptors are complexed within the T-cell and the formation of this complex dictates the susceptibility of the T-cell to activation and to infection by viruses such as HIV. The nature of the interaction between the kinase and the T-cell receptor in a human is also related to the potential for cancer cell formation in that human, and to susceptibility to an autoimmune disease.

Abstract: Sensor arm (5) detects paper (1) at the printing stations of a printer (13). The sensor arm is linked through shaft (37) to position ledge (43) where it encoun­ters and extension (47) of spring clutch (31) to decouple the spring clutch. Sheetfeed (11) is both driven and controlled from the platen (3) of the printer. With the spring clutch deactivated by the presence of paper, pawl (29) continues to hold the sheetfeed in an inactive sta­tus. In the absence of paper, the sensor arm (5) moves past the printing region, moving the ledge (43) away from contact with the spring clutch. Backward movement of the platen then initiates a sheetfeed cycle by movement of gear (35) being transmitted through the spring clutch (31).

Abstract: The time required for the cobalt modification treatment of magnetic iron oxide, which is a long time according to the convention technique, can be shortened and this treatment can be conducted in continuous manner. A magnetic iron oxide powder is covered with cobalt by a preliminary cobalt treatment, and then a cobalt modification treatment is carried out under high-temperature and high-pressure conditions (100 to 200°C and 1.2 to 15 kg/cm²), whereby the total treatment time can be shortened to 2 to 6 hours, although the total treatment time is 9 to 50 hours in the conventional process. Moreover, by carrying out the cobalt modification treatment under high-temperature and high-pressure conditions by using a flow-type reaction vessel, it becomes possible to carry out the treatment in a continuous manner, although the treatment must be conducted batchwise in the conventional process.

Abstract: An active suspension system for an automotive vehicle is provided which regulates relative displacement between a vehicle body and wheels. This suspension system includes first and second gain controllers associated with hydraulic cylinders for supressing vehicular rolling based on lateral acceleration acting on the vehicle body. The first and second gain controllers amplify the level of the lateral acceleration, monitored by a sensor, by first and second gains respectively to vary pressure of the hydraulic cylinders. The suspension system further includes a low-pass filter which restricts a frequency of a signal output from the acceleration sensor higher than a preselected cutoff frequency to decrease the second gain relative to the first gain to reduce the degree of load shift for the rear wheels relative to that of the front wheels.

Abstract: There is provided a photosensitive medium (17) for recording a charge latent image, composed of a photo-­conductive layer (4) having an electrode (3) and a protective layer (18) at each surface thereof. There is further provided a charge latent image recording method. A photo-conductive layer (4) and a charge holding layer (6), each having an electrode (3 and 7) at a surface thereof, are arranged to face each other through a gap. A predetermined voltage is applied across the photo-­conductive layer and the charge holding layer (4 and 6) through the electrodes (3 and 7) to cause discharge thereacross. At the time, an electro-magnetic wave corresponding to the charge latent image intended to be recorded is emitted to the photo-conductive layer (4). The impedance of the photo-conductive layer (4) is thus varied to record the charge latent image on the charge, holding layer (6). In the method, the rise time constant of the voltage applied across the electrodes (3 and 7) is adjusted to that of the discharge or more, and the potential of the charge latent image is adjusted to a discharge starting voltage or less.

Abstract: An extended dwell shock sensing device (10) is constructed to operate in two stages. A carriage (34) that includes a magnet (40) is slidably mounted between a first abutment (20) and a second abutment (22). The carriage (34) also includes a cradle (52) in which a non-magnetic mass (54) is slidably mounted between a first wall (53) and a second wall (55). At a rest position, the carriage (34) is biased away from the second abutment (22) by a spring (50) and the non-magnetic mass (54) is biased away from the second wall (55) by a spring (58). A reed switch (24) is mounted to be responsive to the position of the magnet (40). Upon application of an acceleration force, the shock sensing device (10) operates in two stages. In a first stage, the carriage (34) travels to a position where it approaches the second abutment (22), and activates the reed switch (24). In a second stage, the non-magnetic mass (54) travels toward the second wall (55). The inertia of the non-magnetic mass (54) resisting a rapid change in the return direction of the carriage (54), combined with the relatively long distance to travel back to the first stage position extends the time that the reed switch (24) stays activated.

Abstract: An automatic focusing system includes an active range finding system (11) and a passive range finding system (12). An initial measurement is made by the active range finding system (11). If the initial measurement indicates that the lens focus is within a predetermined scope, control of further focusing is transferred immediately to the passive range finding system (12). If this condition is not met initially, lens focusing begins based on data from the active range finding system (11). The difference between measured range and the distance at which the lens (23) is focused is monitored. When this difference falls below the predetermined scope, the range finding function is transferred to the passive range finding system (12). Also, the variance between the distance measured by the active range finding system (11) and the distance at which the lens (23) is focused is used to determine a degree of blur. If the degree of blur is less than a predetermined blur, the range finding function is transferred to the passive range finding system (12). In one embodiment, the active range finding system (11) employs a plurality of spaced-apart light emitters (13) that illuminate physically spaced-apart objects.
