Title: Current generation circuit for array element
Inventor: UENISHI KATSUJI
IPC: H01L27/04
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To enable such control that current outputs of current generation circuits of all channels are at the same level by a single common reference voltage signal input. SOLUTION: A single reference power supply input is used as a control signal. Transistors(Tr) 101-10n of a plurality of channels are installed near a control signal input terminal and in a locally concentrated manner on an integrated circuit chip. A common input reference voltage source supplies a current control signal to the base of each of the transistors, and constant-current generation circuits 100A-100N connected to a common ground line with resistors 201-20n of the same level are constituted on the emitters of the respective transistors. Current outputs from the collectors of the respective transistor are inputted to array function circuit blocks dispersed within the integrated circuit chip. Also, in place of the external control voltage, an internal reference voltage provided on the same chip is used as the control signal.

Abstract: PURPOSE:To obtain a wound core with good occupancy rate by a method wherein the radius of curvature at an angle section of a magnetic steel belt is alternately changed in long and short length for every layer and a gap is provided between each layer. CONSTITUTION:While applying tension to a magnetic steel belt 3 by a device 7, the steel belt 3 is wound by one turn along a spool 2.
