Abstract: A coordinate-detecting device of a voltage-detecting type, the device including: a coordinate input pad having an upper sheet and a lower sheet opposing each other at a predetermined gap, the sheets being in electrical contact when there is a touch on the coordinate input pad; a voltage-detecting part for alternately detecting voltage values representing an X-coordinate and a Y-coordinate of a contact point; and a control part for generating a coordinate data from the voltage values detected at the voltage-detecting part. The upper sheet and the lower sheet oppose each other at the predetermined gap by a repulsive force between magnetic poles with the same polarity.

Abstract: An improved coordinates input apparatus for designating a particular set of coordinates in three-dimensional space has a substantially box-like frame, a first magnet, a second magnet, and a plurality of magnetoelectric transducers. The first magnet and second magnet are mounted on the frame and disposed so that sides thereof having identical magnetic poles are disposed opposite each other. The second magnet is disposed so as to be tiltable in response to a disposition of forces acting thereupon. The forces include a repulsive force arising between the first magnet and the second magnet and a pressing force exerted on the second magnet. The plurality of magnetoelectric transducers mounted on the frame opposite the second magnet and output voltage values that vary according to a change in a gap between the magnetoelectric transducers and the second magnet, such that the voltage values indicate a set of X,Y coordinates in two-dimensional space.

Abstract: A device includes a coordinate-detecting sheet and a rotating member having a contact part which circularly slides on the coordinate-detecting sheet. Coordinate data of coordinates of the contact part on the coordinate-detecting sheet is output from the coordinate-detecting sheet.

Abstract: A refrigerating system having a refrigerating cycle constructed by connecting an accumulator, a refrigerant compressor, a four-way valve, an outdoor unit heat exchanger, an outdoor unit expander, a receiver, an indoor unit expander and an indoor unit heat exchanger sequentially by pipes. Normally, excessive refrigerant is stored in the receiver and when it becomes necessary to raise a ratio of lower boiling point refrigerants, a flow amount of the refrigerant is decreased by restricting the outdoor unit expander during the cooling operation or by restricting the indoor unit expander during the heating operation to move the excessive refrigerant within the receiver to the accumulator. Thereby, the composition of the refrigerant circulating within the refrigerating system using non-azeotrophic refrigerant mixtures may be changed without using a complicated system structure or control method thereof and the capacity of the refrigerating cycle may be changed.

Abstract: A pointing device includes a resilient substrate having flat upper and lower surfaces, a plurality of strain gages integrally formed on at least one of the upper and lower surfaces of the substrate, and a stick having a base connected to a central portion on the upper surface of the substrate, and a tip end opposite the base and displaceable in an arbitrary direction. The stick extends perpendicularly to the upper surface of the substrate. A displacement direction and a displacement quantity of the tip end of the stick are detectable from outputs of the strain gages.

Abstract: A magnetic sensor including a magnetoresistance effect element directed to prevent deterioration in the detection sensitivity occurring due to inversion of the magnetization of a plurality of ferromagnetic thin film stripes forming the magnetoresistance effect element with respect to the initial direction during the repeated operations, the magnetic sensor being arranged in such a manner that the magnetoresistance effect element is disposed at a position deviating from the center of the magnetic pole surface of a cylindrical magnet, preferably at a position deviating in a direction perpendicular to a direction in which the magnetic object to be detected is moved. The thus-employed arrangement enables a bias magnetic field to be applied to the magnetoresistance effect element in parallel to the deviation direction. Therefore, the magnetization of all of the plurality of the ferromagnetic thin film stripes forming the magnetoresistance effect element can be caused to face the same direction.

Abstract: A position detector having a magnetic sensor for measuring linear or angular displacement, or detecting a position of a body without contact thereto. The detector has a closed circuit including magnets and yokes. The magnetic leakage flux which emanates from the inside surfaces of the yokes is utilized to detect the position of the body. The magnetic sensor is transferred along the inside surfaces of the yokes by a transferring circuit, which senses the magnetic field intensity of the leakage flux distributed thereon. This enables the detector to have a longer measuring range than that of a prior art detectors. An output signal is stable due to the shielding effect of the yokes. The magnetic closed circuit has many magnetic and mechanical configurations. For example, for the magnet, a permanent magnet and an electromagnet can be used.
