  • Patent number: 7098651
    Abstract: A rotation detection sensor, which is a wheel-speed sensor, has a detection unit placed in a metal capped cylindrical casing and a holder fit in an opening of the casing. A flange is provided along the entire edge of the opening of the casing. Between the flange and the holder, a viscoelastic liquid gasket is entirely applied. The edge of the opening of the casing and the exposed part of the holder are covered with a resin portion. Thus, the viscoelastic liquid gasket smoothly enters the gap between the casing and the holder to ensure the gap is closed. Moreover, since the viscoelastic liquid gasket is quickly cured owing to its solvent which is speedily volatilized, the gasket exhibits a good workability. Then, after the solvent is volatilized, a rubber-based elastic sealing material is produced. The sealing material thus withstands any temperature change without problem, it never occurs that the sealing material melts to leak out, and the sealing between the casing and the holder can be ensured.

    Abstract: A rotation detection sensor, which is a wheel-speed sensor (21), has a detection unit (7) placed in a metal capped cylindrical casing (1) and a holder (2) fit in an opening (1a) of the casing (1). A flange (11) is provided along the entire edge of the opening (1a) of the casing (1). Between the flange (11) and the holder (2), a viscoelastic liquid gasket (sealing material) (12) is entirely applied. The edge of the opening (1a) of the casing (1) and the exposed part of the holder (2) are covered with a resin portion (4). Thus, the viscoelastic liquid gasket (12) smoothly enters the gap between the casing (1) and the holder (2) to ensure the closedness between the casing (1) and the holder (2). Moreover, since the viscoelastic liquid gasket (12) is quickly cured owing to its solvent which is speedily volatilized, the gasket exhibits a good workability. Then, after the solvent is volatilized, a rubber-based elastic sealing material is produced.

  • Patent number: 5929939
    Abstract: There is provided a correlation degree operation apparatus in which the search area is readily extensible, in which a high-speed process can be assured even though the search area is extended, and which can be formed in a simple arrangement. The search area memory stores the picture element data of a search area including ((m.times.M).times.L) candidate blocks. The correlation degree operation unit executes an operation of a degree of correlation between a reference picture block and each of the candidate blocks, with the use of picture element data supplied from the search area memory, this operation being executed by a pipeline process for each candidate block group composed of (M.times.L) candidate blocks. The search area memory has the function of supplying four picture element data at the same clock cycle. This enables the correlation degree operation unit to continuously execute the pipeline processes for the candidate block groups.

  • Patent number: 5885066
    Abstract: In a scroll compressor, a gas purge bore is formed to extend from an oil bore penetrating a drive shaft of the compressor, causing coolant gas to be expelled out with rising of lubricating oil sucked up by an oil pump through the oil bore. This allows the lubricating oil to rise without undergoing resistance of the coolant gas. By positioning the oil bore close to an oil groove formed in an eccentric bearing, the lubricating oil can be surely supplied to the oil groove.

  • Patent number: 5664323
    Abstract: Producing vehicles by using a plurality of production lines allowing the vehicles to successively pass through a welding step, a coating step and an assembling step in each line, in accordance with an increase or decrease in the number of vehicles to be produced in the respective production lines, some of the vehicles in one of the production lines which has less of a margin for production are transferred, after passing through the welding step, to another production line at a portion between its welding step and coating step which line has more of a margin for production. With this arrangement, when it becomes necessary to increase or decrease the number of vehicles in the lines, it is possible to produce vehicles without changing the production ability in the respective steps after the welding step, only by adjusting the number of vehicles in the welding step of the production line which has a less of a margin for production.

  • Patent number: 5596518
    Abstract: Stored in each of four coefficient memories are eight elements of each row of a matrix in 4 rows and 8 columns, which matrix consists of absolute values of elements of upper four rows out of an inverse discrete cosine matrix in 8 rows and 8 columns to be subjected to an 8-point IDCT processing. An input element y.sub.ij is supplied in parallel to four multipliers. Each of the four multipliers executes multiplication of an output of the corresponding coefficient memory out of the four coefficient memories, by the input element y.sub.ij. Eight accumulators are disposed for executing, in parallel, accumulation for obtaining eight inner products using results of the four multipliers while restoring signs of the coefficients of the orthogonal transform matrix. An 8-input selector is disposed for successively selecting results of the eight accumulators to supply an inner product w.sub.ij corresponding to the input element y.sub.ij.

  • Patent number: 5583803
    Abstract: The two-dimensional DCT (discrete cosine transform) of plural n.times.n data items is carried out at high speed, with requiring less hardware. X(h) is an operation in which row vectors of A(h) are sequentially transmitted from a first memory to a one-dimensional DCT processor for product-of-matrices computations and the products thus found are sequentially written to at addresses of corresponding row vectors of B(h) of a second memory. Y(h) is an operation in which column vectors of B(h) are sequentially transmitted from the second memory to the one-dimensional DCT processor for product-of-matrices computations and the products thus found are sequentially written to at addresses of corresponding column vectors of C(h) of the first memory. The operation X(h) starts at h=1 and ends at h=m. Then, the operation Y(h) starts at h=1 and ends at h=m. The one-dimensional DCT processor performs the pipelining operation of n-element one-dimensional vectors for product-of-matrices computations.

With this arrangement, when it becomes necessary to increase or decrease the production of vehicles in the respective production lines, it is possible to produce vehicles with high efficiency without changing the production ability in the respective steps after passing through the welding step, only by adjusting the production of vehicles in the welding step in the production line which has less margin for producing vehicles.

  • Patent number: 5477478
    Abstract: The output of a butterfly unit is entered into a product-sum unit in a forward DCT and the output of the product-sum unit is entered into the butterfly unit in an inverse DCT. The product-sum unit employs, as a bit-string distribution circuit, a register circuit having eight bit shift registers each having a 16-bit parallel input and a 2-bit shift output and the bit shift registers are different in bit width from one another. Data are entered into the bit shift registers with the largest bit-width bit shift register first, such that the respective bit shift registers are shifted rightward by 2 bits per cycle. Four shift registers are disposed between the bit-string distribution circuit and a RAG circuit such that, when bit strings are entered, as delayed cycle by cycle, into eight RAGs of the RAC circuit, the final accumulation results are successively provided from the RACs in a proper order. This reduces the bi-directional DCT processor in circuit arrangement.
