Abstract: Magnetic field sensors are already known which exploit the "planar Hall effect". It is now proposed to produce such magnetic field sensors using ferromagnetic amorphous metals. Amorphous metals made of Co75Fe5B20 or Co80B20 are particularly suitable for this purpose. The sensitivity of such magnetic field sensors is markedly higher than that of conventional ones normally produced using permalloy. Such particulary sensitive magnetic field sensors also make it possible to construct novel position sensor devices. Examples of these are given. <IMAGE>

Abstract: A DC power switching circuit is disclosed connecting a load to a DC power source (Jl-A3) while suppressing arcing across a relay in the network. A normally open relay (K2) has its energizing coil (X1-X2) connected to the control input (22) of the circuit, the opposite end (X2) of the coil being connected to the gate of a silicon controlled rectifier (SCR101). The SCR has its principal current conducting path connected between the load and the DC power source (J1-A3), for conducting current between the load and the power source during a first delay interval, thereby reducing the potential difference between the contacts (Al-A2) of the relay (K2) so as to prevent its arcing during the closure of the contacts (A1-A2). An FET device (Q103, Q104) has its principal current conducting path connected between the load and the DC power source (J1-A3) and has its gate (R30, C7, R31, U1D, CR7, R26, C8) connected to a timer. The timer has a control input connected to the control input (22) of the circuit so that it turns on the FET (Q103, Q104) for a duration of a second delay interval in response to an off signal at the control input (22) for the circuit so that the relay contacts (A1-A2) are shunted while they are opening from a closed state, thereby preventing arcing across the contacts. In this manner, the relay (K2) is protected from arcing both on opening and closing of its contacts (A1-A2).

Abstract: A composite glass/plastic ophthalmic lens consists of a thin layer (40) of glass, preferably photochromic, adhered to the front of a plastic layer (30), by a highly elastic adhesive (36). The rear surface (42) of the glass (40) has a different radius than the front surface (32) of the plastic (30) so that the space between the lenses forms a tapered gap which is filled by the elastic adhesive. The edge thickness of the elastic adhesive is sufficient to insure that the increase in diameter of the plastic layer with respect to the diameter of the glass layer due to differences in the thermal expansion characteristic of the glass and the plastic will not damage the lens even over a temperature range > 300°F (170°C).The glass layer (40) is shaped to have a power which compensates for differences in the index of refraction of the glass (40), adhesive (36) and plastic layer (30), and which compensates for the optical powers produced by the tapered adhesive layer, so that the composite lens can be finished to prescription as though it were an all-plastic lens.

Abstract: A reciprocable push button switch achieves sequential switching (ON/OFF or ON/ON) through a simple coil spring (28) and pivoted contact lever (26). A push button (14) of the switch has depending abutment means (14e, 14f) which cooperate with camming means (40,42) inside the switch case (10) to swing the contact lever (26) from side-to-side as it pivots about a first axis (32) between its limit positions. The camming means (40,42) contribute to an additional swinging motion about a second axis (35) to locate the ends (26a, 26d) of the lever (26) alternately in a position for operation by the abutment means (14e, 14f). The resulting compound contact lever action is achieved with a straight line push button motion.

Abstract: (D An optical display system (10) employs a holographic optical element (20 or 22) that has a holographic fringe pattern which is coordinated with the phosphor emission peak (32) of a cathode ray tube (24) to eliminate perceptible variations in image brightness. The holographic optical element has a reflection characteristic (34) that defines two diffraction efficiency peaks (36 and 38) which are resolved by a low diffraction efficiency dip (40) that is interposed between them. The optimum wavelength spacing between the two diffraction efficiency peaks for a given wavelength spacing is determined by computing for all observer (28) head positions and look angles of concern the differences among the areas under the intergrated efficiency characteristics (42) for the reflection characteristic (30) holographic optical element and the phosphor emission characteristic of the image-producing cathode ray tube. The optimum wavelength spacing is that which provides the desired variation among the computed difference values, which represent the display brightness uniformity. The center dip reflection characteristic increases the spectral bandwidth of the holographic optical element and thereby increases its reflectivity to promote good contrast with the use of a cathode ray tube operating at reduced beam current levels. When installed as a combiner (12 or 14) in a head-up display system (10) for aircraft, the holographic optical element superimposes the image on an outside scene without introducing significant discoloration of the scene.

Title: Tensioner for toothed drive belts
Inventor: KIMURA KAZUO C O TSUBAKIMOTO C
IPC: F16H7/08
Filed: 1986-06-13
Abstract: A tensioner for toothed belts comprises a hydraulic fluid filled cylinder having a piston with a rod projecting out of the cylinder and engaging a pivoted arm with a roller at one end for engaging the belt. A spring within the cylinder urges the rod in the projecting direction, and a check valve carried by the piston allows the rod to project rapidly to take up slack in the belt. Hydraulic fluid, however, flows through the small clearance between the piston and the cylinder wall as the rod retracts, and therefore limits the rate of retraction. This prevents the teeth of the belt from jumping over the teeth of its driving and driven wheels, which tends to occur particularly during momentary reverse rotation. 
     The cylinder unit may have a built-in or remote fluid reservoir. In the case of the built-in reservoir, a path is provided between seals surrounding the rod to route air directly to the reservoir so that it does not enter the fluid chambers within the cylinder. The piston material is chosen to expand more rapidly than the cylinder with increasing temperatures to reduce variations in leak-down time. A valved bypass passage may be provided to permit rapid withdrawing movement of the piston rod for belt replacement. This can be accomplished by providing a recess in the piston cooperating with a passage in the cylinder wall so that when the piston rod is rotated 90 degrees, the rod can easily be pushed into the cylinder. A sealed air accumulator can be provided to accommodate differences in variations of the volumes of the chambers on both sides of the piston in order to prevent leakage of fluid out of the cylinder and prevent air from entering the cylinder.

Abstract: A switch node (104-0) for the communication of circuit switched and packet information via parallel electrical and photonic connections within the node between input links (114-0) and output links (115-0). The links each have electrical (311-0) and optical (312-0) sublinks. A node (104-0) is responsive to an address (FIG. 2) received via the electrical sublink (311-0) of an input link (114-0) to establish both an electrical and photonic connection for the subsequent communication of both electrical and photonic data to an output link (115-0) designated by the address. The switch node (104-0) selects the designated output link from a set of similarly address designated output links all of which are equally capable of establishing the path. Based on this type of selection within the node, a switching network with a plurality of stages using the nodes has multipaths between any given input port to any output port.
