Abstract:
A semiconductor pressure transducer comprises a circular diaphragm formed of a single crystal semiconductor material, at least a first strain gauge element having a piezoresistance effect and formed by injecting an impurity into the diaphragm in a linear region extending in parallel with a predetermined axis which extends transversely of the surface of the diaphragm, at least a second strain gauge element having the piezoresistance effect and formed by injecting an impurity into the diaphragm in a linear region extending in the direction perpendicular to the axis, and means for securing the diaphragm at the outer peripheral portion thereof. The distance between the second strain gauge element and the center of the diaphragm is differed from the distance between the center of the first strain gauge element and the latter.

A capacitive sensor sheet producing method for producing a capacitive sensor sheet uses a base having an insulative base layer on which a binder resin layer including conductive nanowires is formed. The conductive nanowires partially projecting from a surface of the binder resin layer. The method includes removing a binder resin from projections of conductive nanowires partially projected from a plurality of detection electrodes by implementing a surface etching and shaping treatment on a surface of the binder resin layer, or surface ends of at least partial detection electrodes of the plurality of detection electrodes, forming wiring lines of the conductive pattern layer, and connecting the wiring lines to the surface ends of at least partial detection electrodes in the pattern layer. The projections of the conductive nanowires removed the binder resin are put into contact with the connecting portions.
Abstract:
The apparatus includes: orthogonal transforming means for orthogonally transforming an input video signal for each element block, quantizing means for quantizing each obtained transformation coefficient using a quantization parameter; coding means for coding the quantization parameter; decoded picture generating means for generating a reference picture signal for a motion compensation prediction from the quantized results of the quantizing means; filtering means for filtering the obtained reference picture signal at a strength corresponding to the quantization parameter when a non-zero effective transformation coefficient is present with respect to the element block; and controlling means for controlling at least anyone of transformation coefficients to be not zero, when all of the transformation coefficients are zero. This allows, even when all of the quantized results of the transformation coefficients of the element blocks are zero, coding of quantization parameter of current element block and control of filtering strength.
Abstract:
An electronic device requires an electronic component to be mounted for the purpose of static shielding. The mounting of such an electronic component raises a problem of avoiding thermal stresses and cracks generated due to the difference between the coefficients of linear expansion of component materials. A positioning recess, a joining-substance thickness ensuring recess, a joining-substance thickness ensuring projection, etc. are formed in a combined manner in an electronic component mount portion of each of leads, whereby spreading of cracks generated in the joining substance can be suppressed and reliability can be improved. Filling a sealing material so as to seal and restrain the electronic component mounted in the electronic component mount portion without leaving voids contributes to further suppressing spreading of cracks generated in the joining substance and ensuring more improved reliability of the joining substance.
Abstract:
An encoding apparatus having a direct mode as a prediction mode, when a pixel with opposite parity from a top field to a bottom field, for example, is referred to for obtaining a reference vector in the direct mode, performs correction by adding or subtracting a value corresponding to a half pixel to or from a value of the obtained reference vector. The encoding apparatus, when a pixel with opposite parity is referred to for obtaining a first and a second direct vector by temporally scaling the corrected reference vector, performs correction by adding or subtracting a value corresponding to a half pixel to or from values of the obtained direct vectors.
Abstract:
A virtual sensitivity value which is obtained, variously changing a pupil diameter is measured in advance for many examinees, and volume of correction which is necessary at the time when the sensitivity value is corrected into one in a standard pupil diameter is stored as correction volume database. An apparatus has measurement means for measuring the pupil diameter of the eye to be examined, computing means for computing a shape parameter rate of the measured pupil diameter to the standard pupil diameter, and judgment means for computing volume of correction by referring to the correction volume database from the shape parameter rate and correcting the virtual sensitivity value obtained by measurement of the eye to be examined and for judging a sensitivity step of the eye to be examined.
Abstract:
A non-contact sensor for sensing a rotational position of a rotating object is provided. A ring-shaped permanent magnet magnetized in the axial direction is sandwiched between two pairs of magnetic plates from above and below. Two pairs of upper and lower protruded magnetic substance portions are provided between the upper and lower magnetic plates at opposite outer ends thereof. Magnetic sensitive devices are inserted in air gaps between the two pairs of upper and lower protruded magnetic substance portions. A magnetic flux generated from the ring-shaped permanent magnet is substantially concentrated to the protruded magnetic substance portions and passes the magnetic sensitive devices. The amount of magnetic flux passing each magnetic sensitive device is substantially proportional to the rotational angle of the ring-shaped permanent magnet. The rotational position of the ring-shaped permanent magnet and hence the rotational position of a rotating shaft supporting the ring-shaped permanent magnet can be sensed in a non-contact manner as a signal output from the magnetic sensitive device. Since the magnetic flux is effectively concentrated to positions where magnetic sensitive devices are attached, a non-contact rotational position sensor having high accuracy and high sensitivity can be obtained.

Abstract:
The object of the present invention is to propose an etch channel sealing structure characterized by excellent impermeability to moisture and resistance to temporal change of the diaphragm in the pressure sensor produced according to the sacrificial layer etching technique, and to provide a pressure sensor characterized by excellent productivity and durability. After a very small gap is formed by the sacrificial layer etching technique, silicon oxide film is deposited by the CVD technique or the like, there by sealing the etch channel. Further, impermeable thin film of polysilicon or the like is formed to cover the oxide film. This allows an etch channel sealing structure to be simplified in the pressure sensor produced according to the sacrificial layer etching technique, and prevents entry of moisture into the cavity, thereby improving moisture resistance. Moreover, sealing material with small film stress reduces temporal deformation of the diaphragm.
