Patent EP-0246597-A2 (EP)
Inventor: NAGASHIMA MICHIYOSHI
IPC: G11B7/007
Filed: 1987-05-18
Abstract: A method of reproducing signals formed in slant surfaces of a V-shaped track groove formed in an optical disk. The beam reflected from each slant surface has a portion having a small crosstalk component and a portion having a large crosstalk component, the portions existing separately. The beam reflected from the V-shaped track groove is detected by a photodetector which is composed of two photodetector units. Thus, the output from the first photodetector unit has a small crosstalk component, while the output from the second photodetector unit has a large crosstalk component. The reproduced signal is obtained by subtracting, from a signal formed by amplifying the output of the first photodetector unit, a signal formed by amplifying the output of the second photo­detector unit, so that the crosstalk component in the signal from the first photodetector unit is negated by the crosstalk component in the signal from the second photodetector unit, so that the reproduced signal can have a reduced crosstalk component. At the same time, the strictness of requirement for design and positional accuracy of the photodetector is reduced. It is also to arrange such that signals are simultaneously and inde­pendently reproduced from adjacent slant surfaces of the V-shaped track groove by a single laser beam spot.

Abstract: A method and apparatus for measuring structural characteristics of a manufactured circuit board containing solder joints by automated real-time digital X-ray radiographic inspection techniques. A circuit board under examination is automatically positioned by a digitally controlled multi-axis positioning system between an electronic X-ray source and an electronic X-ray imaging system. X-rays, in a beam of X-rays from the X-ray source, are directed towards the circuit board. The X-rays are absorbed, scattered and transmitted through the circuit board. The X-rays transmitted through the circuit board are directed upon the X-ray imaging system. The X-ray imaging system converts the transmitted X-rays into digital images which represent the radiographic density of the portion of the circuit board under examination. The digital images are stored within a digital image processor. A computer, under program control, performs calculational measurements on the digital images so as to measure the structural characteristics of the solder joints and components on the circuit board. The calculational measurements are compared to predetermined standards corresponding to acceptable quality standards programmed into the computer. In response to the comparison, the computer provides an accept/reject decision on the circuit board in addition to providing manufacturing process control information for correction of found defects.

Abstract: The present specification discloses a heat transfer device (1) for use in transferring heat to or from a material. Conventionally material is heated or cooled from the outside so that the surface layer of the material is first cooled or heated and then thus forms a heat barrier to the further cooling or heating of the centre region of the material. 
     The heat transfer device (1) of the present invention provides an elongate hollow body (3), preferably in the form of a needle, with an elongate inner duct member (5) extending through said body (3). Heating or cooling fluid can be passed through the inner duct member (5) and back along the gap (15) between the body (3) and the inner duct member (5), and by piercing the relevant material, the material can be heated or cooled from the inside out. This thus reduces the heat barrier problem referred to and allows the heating or cooling to be effected relatively quickly and more efficiently.

Abstract: An aircraft towing vehicle has a rearwardly opening recess adapted to receive the nose wheel of an aircraft to be towed. A nose wheel lifting and clamping mechanism has two nose wheel lifters which can be pivoted from a retracted position, in which they are parallel to sides of the vehicle frame, into an operative position, in which they extend into the recess for engaging the aircraft nose wheel. The lifters pivot on rocker arms which themselves pivot about a horizontal axis and are power driven by hydraulic actuators. A separate hydraulic swivel drive motor is provided for each lifter. The pressure increase which takes place when the swivel drive reaches the end of its path is used to initiate the delivery of pressurized fluid to the actuator. A crank arm driven by the hydraulic motor is connected to the support for the lifter with a low back pivot, self locking linkage to positively prevent even excessive forces generated during the nose wheel lifting process from unintentionally moving the lifters towards their retracted positions.

Abstract: On cassette tape recorders having two rubber pinch rollers and capstan spindles for reverse mode, it is known to bring the cassette drive into a neutral position after switching off, in which position both the rubber pinch rollers are lifted off from the capstan spindles. The invention provides for this neutral position to be reached after switching off the operating voltage of the cassette tape recorder by influencing the reverse switching member provided for the various playback mechanisms in such a way by a ratchet wheel that the desired neutral position is attained. The ratchet wheel in this case serves at the same time to act on the reverse switching member in such a way that the desired different playback directions can be assumed. The neutral position can thus be reached without the entire head support of the cassette tape recorder being moved together with the rubber pinch rollers with the aid of a complex servo-drive in order to move the rubber pinch rollers away from the capstan spindles in a complex way - as is usually the case with known cassette tape recorders. <IMAGE>

Abstract: The present invention relates to methods, compositions, and apparatus for treating and upgrading the tenderness and sensory qualities of fresh red meats. The present invention provides a mechanism whereby low grades of meat may be made tender, flavorful, and juicy without significantly increasing saturated fat content. This is accomplished by injecting the meat with appropriate injectates. Such injectates may include unsaturated vegetable fats such as corn oil, water, and even beef tallow or other saturated fats. It is presently preferred to include a binder in the injectate such that a substantial portion of the injectate is retained within the meat even after cooking. Failure to provide a binder often results in a drier tasting meat product. 
     The present invention also teaches the construction of an apparatus which allows injection in a sanitary manner. Additionally, injection can be accomplished such that the meat product may have the appearance of natural marbling.

Abstract: A cathode arrangement for a flat electron beam display device has an opposing electrode (6), a plurality of heating wires (7) parallel thereto and an attracting anode (5), likewise parallel to the opposing electrode. Focusing wires (8) and attracting wires (9) are additionally present, running parallel to the cathode wires. The attracting anode is designed such that it has in each case a plurality of transmitting lines for each cathode wire. As a result of this arrangement, it is no longer necessary for a separate cathode wire to be allocated to each transmitting line in the attracting anode, but it is adequate to use a single cathode wire in each case for a plurality of transmitting lines. In consequence, considerable heating power can be saved. <IMAGE>
