Abstract: To provide a method for manufacturing a color selection electrode structure easily capable of measuring a tension amount of the color selection electrode in the process for manufacturing the color selection electrode structure and a color cathode ray tube using the color selection electrode structure. The color selection electrode is stretched with tension applied in the direction of the shorter axis thereof, and welded and fixed onto the top face that is curved inwardly in the direction of the longer axis of the longer side members. Thereafter, the weight is placed on the color selection electrode so as to allow the color selection electrode to deflect by the load due to the mass of the weight. The deflection amount of the color selection electrode may be measured by using a laser displacement meter and the measured deflection amount of the measured color selection electrode is converted into the tension amount by the correlation graph.

Abstract: A displacement transducer capable of measuring very small displacements (on the order of 100 &mgr;m or less) comprises a strain gage mounted to the curved arc of a substrate. The transducer has a resolution of at least 10 &mgr;m, preferably at least 1 &mgr;m or better. The transducer can measure positive or negative displacement in a specimen and can also be used as an extremely sensitive load cell for very high resolution weight, load or mass determinations.

Abstract: The present invention is based on an use of the already existing actuator bottom as a deformation element for a direct measurement of braking force, and on its geometric configuration in order to measure a force in a way which is largely independent of temperature and free of hysteresis. Accordingly, a force sensor is integrated into an actuator for generally or transmitting a force in the force flux. The actuator bottom is transverse to the force flux.

Abstract: Vehicle seat including a cushion defining a surface adapted to support an occupying item, a spring system arranged underneath the cushion and a sensor arranged in association with the spring system and/or cushion for generating a signal based on downward movement of the cushion caused by occupancy of the seat which is indicative of the weight of the occupying item. The sensor can be a spring retained at both ends and which is tensioned upon downward movement of the cushion whereby a force in the spring indicative of weight of the occupying item is measured. The sensor can also include strain gages, e.g., SAW strain gages.

Abstract: A shapemeter for measuring the flatness of a tensioned metal strip has a plurality of coaxially aligned measuring rings, with each measuring ring being rotatably supported on the outer circumference by an associated force sensor.

Abstract: A seat belt tension sensor is attached to a seat belt in a vehicle. The seat belt tension sensor includes a housing attached between the vehicle and the seat belt. A limit structure is located in the housing. A sensor is attached to the limit structure for generating an electrical signal in response to the sensor being placed in tension. The electrical signal changes as a function of tension on the seat belt. The limit structure moves between a first position in which the limit structure transfers the seat belt tension to the sensor and a second position in which the limit structure transfers the seat belt tension to the housing.

Abstract: There are provided a stable and highly sensitive nanometric mechanical oscillator having a considerably high detection resolution that enables detection of variation in force or mass on the nanometer order, as well as a method of fabricating the same, and a measurement apparatus using the same. A nanometric mechanical oscillator (10) includes a base (11), a tetrahedral oscillator mass (13); and an elastic neck portion (12) for connecting the base (11) and the tetrahedral oscillator mass (13). The oscillator (10) assumes a mushroom-like shape and has a nanometric size. The oscillator mass (13) assumes a tetrahedral shape and is suitable to be used as a probe of a scanning forth microscope in which the oscillator mass (13) serving as a probe is caused to approach to an arbitrary sample surface in order to observe the surface state.

Abstract: An instrument is provided with several sensing elements to enable several parameters of a processed yarn to be measured or determined. In order to minimize the total sensing element/guide contact with the yarn within the complete process threadline, the yarn is guided through the instrument by contact only with the inlet and outlet guiding elements of the instrument and contact operative sensing elements. One particular instrument consists, in succession, of an interlace sensing device, a tension sensing device and an oil content sensing device. The electrical resistance of the yarn is measured between two pins of the oil content sensing device and in this case, the first pin is also a tension sensing pin of the instrument, and the second pin of the oil content sensing device is also the outlet guide of the instrument.

Abstract: An apparatus for measuring the deflection of a belt in an electrophotographic printing machine includes an elongate arm member having a first end and a second end. The second end engages and is displaced by the belt. A gearbox includes a plurality of gears interconnected into a gear arrangement, and a gearbox shaft rotatable by the gear arrangement. The second end of the arm member is coupled to the gear arrangement, which converts displacement of the second end of the arm member to rotation of the gearbox shaft. An encoder is associated with the gearbox shaft. The encoder includes at least one encoder output. The encoder senses rotation of the gearbox shaft and issues electrical pulses on the encoder output. The electrical pulses are indicative of the magnitude and direction of the rotation of the gearbox shaft. A counter includes at least one counter input and at least one counter output. The counter input is electrically connected to the encoder output.

Abstract: The preferred orientation, or planar oscillation plane, of a golf club shaft is located by measuring the oscillation of the shaft when a horizontal impulse is applied and from those measurements determining an orientation in which the oscillation would be substantially planar. In a preferred embodiment an iterative process is used to converge on the preferred orientation. The location of the preferred orientation may be marked on the shaft and used to assemble a golf club with the planar oscillation plane in a predetermined orientation. The assembly of the golf club can be done manually—e.g., in a refitting situation—or automatically—e.g., in a new club manufacturing setting.

Abstract: A pressure sensitive switch disposed in the seat of a vehicle and a seating detector having the pressure sensitive switch are provided. Loss in its production can be reduced for obtaining an inexpensive pressure sensitive switch. The pressure sensitive has a movable contact layer formed underneath a top sheet and a fixed contact layer formed over a bottom sheet. A mark showing the resistance characteristic of the contact layer in the pressure sensitive switch is indicated on the top surface of the top sheet.

Abstract: A seat belt sensor for attachment to a seat belt in a vehicle. The seat belt tension sensor has a substrate with a top surface, a bottom surface and a pair of slots therethrough. The seat belt passes through the slots. The substrate has a pair of apertures. An actuator bar is located adjacent the top surface and has a first and second end that pass through the apertures. The seat belt passes over the actuator bar. A load beam is attached to the substrate and has a first and second end. The ends of the actuator bar contact the ends of the load beam. Strain sensitive resistors are located on the load beam. The seat belt, when placed in tension, causes the actuator bar ends to flex the ends of the load beam placing stress on the strain sensitive resistor. The strain sensitive resistor generates an electrical in response to being placed under stress.

Abstract: A method of measuring the tensile stress distribution in a metal strip between two roll stands, between a roll stand and a coiler, within a blooming stand, or upstream or downstream from a deflection roller, with the metal strip being deflected and the deflection of the metal strip being measured by two or more sensors arranged across the width of the metal strip. The tensile stress distribution in the metal strip is calculated as a function of the deflection of the metal strip. A correction is performed on the measured values of sensors in the edge area of the metal strip whose measurement area is not covered completely by the metal.
