Title: Testing method for device mounted with processor
Inventor: MARUYAMA TORU
IPC: G06F11/30
Filed: 1989-09-14
Abstract: PURPOSE:To easily carry out a test without providing a circuit, etc., required for the test only to a device mounted with a processor by reading the control signal or the data out of a memory and checking the signal or the data in a cycle when the processor uses no bus via its internal process. CONSTITUTION:A processor releases a bus for the application of other devices in a cycle when the processor carries out its internal processes including the instruction interpreting processes, the computing processes, etc. Thus a check address is transmitted to a cycle when the processor does not use the bus and the check data is acquired. Thus it is possible to check the control signal and the data stored in a memory which changes properly in response to the internal process of a device as well as the status of an input/output controller, etc. Therefore the device to be tested is not required to provide a program or a circuit mounted in the memory and outputting the control signal, etc., to the outside. Furthermore a tester is prepared in order to obtain the check data by the timing and to carry out the test. Then the test is attained just by connecting the tester to the bus to be tested. Thus the test is easily carried out.

Title: Data driving automation rating used for data communication
Inventor: MAHENDORA PATERU
IPC: H04L29/08
Filed: 1994-10-04
Abstract: PURPOSE: To effectively transmit data by executing data driving for the automatic rating route of MODEMs in the case of transmitting information from one cellular MODEM to the opposite side cellular MODEM through a cellular communication channel. CONSTITUTION: It is supposed that a MODEM 100 sends information to an opposite side end point 30 through a cellular communication channel. When the quantity of information to be transmitted to the end point 30 is less, the data speed of the MODEM 100 is low. For instance, the data speed is a low level of 4800 bps, and in this case, capacity for automatic rating to the upper side direction of the MODEM 100, i.e., fall forward, is disabled. When the quantity of information to be transmitted to the end point 30 is much, the capacity for automatic rating to the upper side direction of the MODEM 100 is started, so that the data speed of the MODEM 100 is increased to the highest speed allowed to the cellular channel to transmit a block of large information.

Title: Method for controlling air separator
Inventor: SOMEYA KAZUO
IPC: F25J3/04
Filed: 1990-09-12
Abstract: PURPOSE:To get a high recovering rate of argon and perform a control of a stable operation by a method wherein a pressure of argon is detected as a temperature of a main condenser by an air separator for adjusting an amount of nitrogen in gas supplied to a crude argon column for taking argon from it in reference to a temperature difference between a middle part of an upper rectifying column and a main condenser, its saturation temperature is calculated and controlled. CONSTITUTION:As a temperature of a middle part of an upper rectifying column is detected, a temperature at a point B is detected. A temperature of a main condenser is calculated by detecting a pressure at a point A. This temperature difference is set in such a way as a concentration of argon in a feeding gas is kept as high as possible and an amount of included nitrogen is less than its allowable limit value. If the temperature difference is set to 10 deg.C, for example, and an operation for decreasing an amount is changed to an operation for increasing the amount, a pressure at a main condenser of the upper rectifying column is increased. If this value is increased from 1.4kg/cm<2>abs to 1.6kg/cm<2>abs, the temperature of the main condenser is varied in its saturation temperature from -180 deg.C to -178.6 deg.C, so that the temperature controlled value at the middle part has a constant temperature difference, resulting in that it is varied from -190 deg.C to -188.6 deg.C. With such an arrangement, it is possible to increase a feed gas composition and to perform a high recovering and stable operation for argon.

Abstract: PURPOSE:To reduce the number of connectors in a mix substrate and to easily lead a pattern as well. CONSTITUTION:CH1-CH6 are inputted to a channel substrate 2 via a buffer 1, and the processing of format conversion and equalizing, etc., are applied to audio data on each channel, and there after it is inputted to the mix substrate 41. Prescribed audio data out of the one on each channel is selected at the mix substrate 41, and mixing processing, etc., is applied to it. The audio data for which the processing is applied, after the format conversion being applied, is outputted to the connector 6 as bus out, and it is outputted and derived via a buffer 11. Also, the audio data for which the processing is applied is outputted to the connector 42 as meter out and cascade out without applying the format conversion. Such audio data are set as the meter output via a D/A converter 12. Since the connector 42 is used as the meter out also as the cascade out, the number of connectors can be reduced, and the leading of the pattern can be also simplified.
