Title: Method for transferring data
Inventor: NISHIMURA TAKUYA
IPC: H04N21/4363
Filed: 1995-04-21
Abstract: PURPOSE:To efficiently transfer a data packet having a variable length data header by the use of an end flag and a format flag by indicating an end by an end flag in an N-th header element counted from the leading header element and continuation by the end flag of a header element other than the N-th one. CONSTITUTION:In a data header 303, an end flag 100 included in a 1st header element 109, e.g. indicates whether or not header elements are continued succeeding to the element 109. Namely, when the value of the end flag 100 is '0', header elements are continued succeeding to element 109, and when the value is '1', no header element is continued succeeding to the element 109. A format flag 103 is combined with the flag 100 to specify a description format of a header 106. Thus an equipment receiving packet judges the end of the data header 303 based on the contents of the end flags 100 to 102 included in respective header elements 109 to 111.

Title: Digital/analog converter
Inventor: HATTORI SHIGEO
IPC: H03M1/66
Filed: 1995-04-21
Abstract: PURPOSE: To reduce a consumed current in a digital/analog converter as a whole device including an analogously operating part and a digitally operating part. CONSTITUTION: This converter is a digital/analog converter in a power supply matrix system, and it includes an operational amplifier 1 provided with a control circuit to reduce the consumed current at the time of non-operation and a current changeover circuit part 2. A constant current source element P9 is controlled by using the output signal of this operational amplifier 1. When the digital/analog converter is in a non-operating state, a flow-through current of the operational amplifier 1 is cut off by a current control signal, and the output terminal of the amplifier is turned into a pull-up state. Accordingly, since the constant current source element P9 too is tuned into the pull-up state, and the current of the constant current source element P9 is cut off, the consumed current of not only the analogously operating part but also the digitally operating part can be reduced at the time when the digital/analog converter needs not operate.

Abstract: PURPOSE:To obtain a second address transition detecting pulse in which both edges of a fall and a rise are steep and the pulse width can be correctly controlled by synchronizing and making variable the impedance of the load element of the second address transition detecting circuit to the change of an address. CONSTITUTION:When a load impedance control signal line 24 comes to be an 'L' level, the impedance of a load element 21 comes to be very low, and the second address transition detecting signal line 22 is quickly charged through the load element 21 and comes to be rapidly an 'H' level. Namely, when the second address transition detecting signal line 22 should discharge, the impedance of the load element 21 is highly set and when the line should charge, the impedance of the load element 21 is lowly set. Thus, both the fall and rise of the second address transition detecting pulse 9 are steep, and the pulse width can be correctly controlled by the pulse width of the first address transition detecting pulse 5 and a load impedance control circuit 23.
