Abstract:
A microscopic geometry cutting device includes: a controller that outputs a timer count start command in starting a driving program which controls a drive of an X-axis or a Y-axis moving mechanism; an arrival time calculator that calculates an arrival time from when the timer count start command is output till when the cutter arrives at a machining start position in accordance with relative moving speed information of the moving mechanisms and machining start position information of a workpiece W; an elapsed time determiner that determines whether an elapsed time from when the timer count start command is output is coincident with the arrival time and outputs a trigger signal when the elapsed time is coincident with the arrival time; and a reciprocating stage driver that drives the reciprocating stage in a manner that the cutter advances and retracts in a predetermined cutting depth in response to the trigger signal.
Abstract:
Provided is a machine tool spindle balancer that stably pulls and biases the spindle unit upward and thus reduces the load of the lift means for moving the spindle unit vertically, is easily applicable to existing machine tools, highly durable, downsizable, and has a simple structure advantageous in production cost.A spindle balancer 30 comprises a gas spring 31 having a cylinder body 32, a rod 33, and a compressed gas. The gas spring 31 is provided above the spindle unit 10. The bottom end of the rod 33 is coupled to the spindle unit 10 so that the spindle unit is pulled and biased upward by the biasing force of the gas spring 31 that is applied on the rod 33, whereby the biasing force of the gas spring 31 serves to reduce the load of the lift mechanism 20.
Abstract:
In an image encoder, a first quantization section which is selected when normal image quality is required performs quantization by dividing a wavelet transformation coefficient by a quantization step size and by thereafter rounding down a fraction thereof. On the other side, a second quantization section which is selected when high image quality is required performs quantization by dividing a wavelet transformation coefficient by a quantization step size, by adding 0.5 to the addition result, and by thereafter rounding down a fraction thereof. Therefore, the width of a dead zone where coefficients are quantized to a value of 0 is narrower than that in the first quantization section, and higher image quality is obtained accordingly.

Abstract:
A video signal processing method includes the steps of processing an input video signal and outputting an output video signal, detecting a temporal feature from the input video signal, smoothing the temporal feature by filtering and outputting the smoothed temporal feature, and controlling processing performed in the processing step in accordance with the temporal feature smoothed in the smoothing step. In this method, the smoothing step switches a characteristic of the filtering in accordance with the attribute of the input video signal.
Abstract:
In an image synthesizer (1), code stream analyzers (10, 11), code block extraction units (12, 13) and EBCOT decoders (14, 15) work together to decode encoded code streams (D10, D11) encoded according to the MPEG-2000 Standard and generate quantization coefficients (D16, D17) for each code block. In a cross-fading unit (16), multipliers (17, 18) multiply the quantization coefficients (D16, D17) by coefficients (α(t), (1−α(t))) and an adder (19) adds together the results of multiplication to provide a cross-fading quantization coefficient (D20). An EBCOT encoder (20), rate controller (21) and code stream generator (22) work together to encode the cross-fading quantization coefficient (D20) to provide a final encoded code stream (D23). Therefore, the image synthesizer (1) can combine two encoded code streams easily and effectively with a reduced use of a memory capacity.
