摘要:
To reduce pseudo errors.A stationary signal is propagated through the circuit to be checked. A combination is extracted in which different asynchronous transfers occur between a transmitting side register and a receiving side register. From the extracted combination of asynchronous transfers, a circuit to be checked is extracted, and a synchronization circuit of a plurality of signals is excluded from the circuit to be checked. A stationary signal is propagated through the circuit to be checked, for each combination among all combinations of logic values “1” and “0” of the stationary signal. It is checked whether or not there exists one asynchronous transmitting side register to which signal change can logically reach, in the combination of logic values of the stationary signal propagated. Based on the result, it is determined whether or not the circuit is appropriate as a synchronization circuit for a single-signal transfer, thereby reducing pseudo errors.
摘要:
A welding control apparatus according to the present invention includes an integrator for starting calculation of a voltage error integral value Sv2, expressed by a formula (1) given below, from a time when a first pulse period ends and a second pulse period starts in a pulse cycle, based on various data of information regarding a gradient Ks of an external characteristic of a welding power supply and a welding current setting value Is2 and a welding voltage setting value Vs2 both in a second pulse period, which are preset as parameters in the formula (1), as well as on an instantaneous value Io2 of a welding current and an instantaneous value Vo2 of a welding voltage both detected in the second pulse period, a comparator for comparatively determining whether a value of the voltage error integral value Sv2 provided as the calculation result has become 0, and a waveform generator for, per pulse cycle, terminating the relevant pulse cycle and starting a next pulse cycle at a time when the value of the voltage error integral value Sv2 has become 0, whereby a variation in an arc length caused by disturbances is precisely suppressed in pulse arc welding of consumed electrode type: Sv2=∫{Ks(Io2−Is2)+Vs2−Vo2}dt (1)
摘要:
Disclosed is a menu distribution system that provides a menu, which is viewable in a conventional manner and is customized for each customer. A customer allows a read/write device to read a customer ID information storage medium storing customer ID information. The read/write device transmits the customer ID information to a menu server. The menu server has a customer information storage unit that stores, for each customer, attribute information such as food preferences. The menu server selects a menu item most suitable for the customer identified by the transmitted customer ID information, by comparing customer attribute information and menu items stored in a menu item information storage unit. Menu image data is generated based on the selected menu item and is transmitted to the read/write device. The read/write device writes the received menu image data to a memory of a paper like display.
摘要:
A code stream generating part converts image data into two-dimensional wavelet coefficients, quantizes the same and coding the quantization result so as to compress the image data and generate a code stream. An additional information creating part creates additional information concerning the image data, and an additional information embedding part embeds the thus-created additional information into the code stream as a code in an off-rule zone which is not decoded by a JPEG 2000 standard rule.
摘要:
An image decoder comprises a code decompression/decoding unit that decodes code data produced through compression and encoding of image data, a power supply state detection unit that detects a current state of a power supply of the image decoder, and a controller that controls the code decompression/decoding unit based on the current state of the power supply so as to reduce power consumption in performing decompression and decoding of the code data.
