摘要:
The invention provides a low-pass filter suitably used as a loop filter for a PLL or a DLL that has a filtering characteristic equivalent to that of a conventional one and can be realized in a smaller circuit area. The low-pass filter includes first filtering means (31) for accepting, as an input, an input signal to the low-pass filter and outputting a first voltage; a circuit element (311) included in the first filtering means (31) for allowing a first current to flow in accordance with the first voltage; current generating means (32) for generating a second current at a given rate to the first current; second filtering means (33) for accepting, as an input, the second current and outputting a second voltage; and adding means (34) for adding the first voltage and the second voltage and outputting an output signal of the low-pass filter, in which the second current is set to be smaller than the first current.

In encoding, index information indicating a group of coefficients that minimizes the sum of the error between the value of each sample and the value obtained by multiplying the quantized value of the sample by a coefficient corresponding to the position of the sample, for all sample positions, among a plurality of groups of predetermined coefficients corresponding to the positions of the samples, is output. In decoding, a plurality of values corresponding to an input vector quantization index are obtained as decoded values corresponding to a plurality of sample positions;and, with the use of a group of predetermined coefficients corresponding to the plurality of sample positions and indicated by input index information, the values obtained by multiplying the decoded values and the coefficients, corresponding to the sample positions are output.

A housing of a high-pressure pump defines a passage communicating with a pressurizing chamber in which fuel is pressurized. The passage has an annular engagement groove which is radially outwardly concaved on its inner wall surface. A valve body is disposed in the passage. The engaged member is disposed inside of the passage wall. A valve body engaging member is comprised of a plurality of arc-shaped plate members, which form circular shape. The valve body engaging member is inserted into the engagement groove in such a manner as to be engaged with the valve body. A C-ring is firmly in contact with the plate members and biases them toward the engagement groove.

A package (2) comprises a box body (4) with an open end (22) at the top, a tongue-lid (6) adapted to close the open end (22), rotatably connected to a rear edge of the open end (22) by a lid hinge (30), and an inner pack (8) enclosed in the box body (4). The inner pack (8) includes an envelope (13) enclosing tobacco items (10) and keeping the inner pack (8) airtight.
摘要:
A functional-level processing unit converts a data path diagram into logic circuit data. A logic-level processing unit specifies cells in a data path circuit based on the logic circuit data. A synthesis processing unit uses geometrical functions of the cells which have been parameterized by delays thereof, thereby synthesizing a layout module for the data path circuit based on the logic circuit data used to specify the cells and on a floorplan for the module. The synthesis processing unit also obtains a geometrical function parameterized by delay for the layout module. By synthesizing a layout module using the geometrical functions of the cells, which have been parameterized by the delays thereof, the geometry of the layout module can be optimized with high accuracy. In addition, by generating a geometrical function for the layout module, it becomes easier to establish a linkage to the upper process of design.
