A portable-device position determination system has a portable device that is configured to be possessed by a user, and an in-vehicle device that is mounted on a vehicle and conducts wireless communication with the portable device. The in-vehicle device transmits a request signal to the portable device. The portable device detects a received signal intensity of the request signal to send back the received signal intensity to the in-vehicle device. The in-vehicle device compares the received signal intensity of the request signal detected by the portable device to a threshold to determine a position of the portable device. The in-vehicle device includes a transmission controller that generates the request signal, supplies an electric power to a transmitting antenna, and transmits the request signal from the transmitting antenna, and a current detector that detects a current passed through the transmitting antenna when the request signal is transmitted.

A control system has a control device for performing a control of a predetermined process, and a communication device for communicating with the control device. The control device has a first transmission unit for transmitting a request signal requesting for transmission of a response signal to the communication device, a first reception unit for receiving the response signal transmitted through a predetermined procedure from the communication device in response to the request signal transmitted by the first transmission unit, an authentication unit for performing authentication of the communication device using identification information of the communication device contained in the response signal received by the first reception unit and identification information of the communication device registered in advance, and a process executing unit for executing the predetermined process when the authentication of the communication device by the authentication unit is successful. The communication device has a first storage unit for storing transmission scheduled time information indicating a time scheduled to transmit the response signal assigned to the communication device, a second reception unit for receiving the request signal transmitted from the first transmission unit, and a second transmission unit for transmitting the response signal corresponding to the request signal received by the second reception unit to the control device at a time different from times assigned to other communication devices based on the transmission scheduled time information stored in the first storage unit.
摘要:
In a pyrometallurgical smelting method of copper, the copper-ore and auxiliary fuel, such as carbonaceous material, is blown through an ore-concentrate burner into a reaction shaft. In an improved pyrometallurgical smelting of copper, the carbonaceous material is used to reduce the Fe.sub.3 O.sub.4 contained in the slag. The present invention provides an improved method for reducing the Fe.sub.3 O.sub.4 even in a case at a decreased amount of auxiliary fuel is to be decreased. The carbonaceous material is blown into a lower portion of the reaction shaft where the oxygen partial pressure is low.

摘要:
In the operation, a flux mainly composed of silica ore and a non-ferrous metal-ore raw-material are charged into a smelting furnace via a conveying system.In order to increase the production amount of the metal, the flux is conveyed and treated through a first system, in which the flux is crushed in a ball mill and dried in the ball mill while hot air is blown into the ball mill, and the crushed and dried flux is conveyed directly before the smelting furnace. In the drier of copper concentrate, the flux is not dried at all.
摘要:
A syndrome sequential decoding system for error correction of a convolutional code has a syndrome former for providing a syndrome sequence from a received sequence, a syndrome buffer memory for storing the syndrome sequence, an estimated error buffer memory for storing an estimated error sequence, a syndrome register for representing a syndrome state under searching, a comparator for testing if content of the syndrome register is all zero, and an algorithm controller. The algorithm controller controls the syndrome register, calculates a path metric and raises a flag in the estimated error buffer memory for showing an estimated error bit position. The syndrome sequential decoding system also includes an exclusive-OR circuit for correcting an information bit error according to the output of the estimated error buffer memory. When the content of the syndrome register is all zero, it shows that a currently searching path merges with the maximum likelihood path. Then a decoded sequence up to this point is explicitly determined. Moreover no further search will be required as long as the following syndromes remain zero. When the content of the syndrome register becomes nonzero, the normal path search restarts at this point. A back search limit pointer is provided on the estimated error buffer memory and a syndrome buffer memory to show the limit of the depth of back search.
