Title: Low voltage bias circuit
Inventor: KATOU KAZUYOSHI
IPC: H03F1/30
Filed: 1984-09-11
Abstract: PURPOSE:To obtain a low voltage bias circuit operated at a wide range by setting widely a value of a stabilized voltage extracted from a collector of the 2nd transistor (TR) in the 1st and 2nd TRs forming a differential TRs. CONSTITUTION:A voltage of a stabilized voltage terminal 12 being a collector of a TRQ5 is used as a stabilized voltage VB and the relation among the bias voltage VS, the voltage VB and a collector-emitter voltage of the TRQ5, VCE(Q5) is expressed as VS=VB, VB=VCC-VCE(Q5). The VCE(Q5) is operated nearly at 0.1V by designing a collector series resistance and in case of VCC=3V, the relation is VB=VCC-VCE(Q5)=3-0.1=2.9V. Thus, the voltage VB has no base- emitter forward voltage of the TR and voltage drop due to resistor drop, then the performance is improved remarkably.

Abstract: PROBLEM TO BE SOLVED: To restrain the development of shrinkage hole in a casting formation process and to obtain a prescribed strength by giving the directivity so as to solidify toward mutually reverse direction from the almost center portion of a cavity when molten metal filled into the cavity in a metallic mold is solidified. SOLUTION: When the metallic mold composed of an upper mold 12 and a lower mold 14 is preheated and the molten metal is poured from a sprue 20, the molten metal is filled into the cavity 16 through a runner 18. After starting the pouring, the heating of the metallic mold is stopped and at the same time, the cooling of the metallic mold is started, and then, the surface layer of the molten metal filled into the cavity 16 is rapidly cooled and changed into a shell-state solidified layer. In such a case, the solidification starts at the almost center portion of the cavity 16, in which the clearance between the bottom surface part of the upper mold 12 and the upper surface part of the lower mold 14 is the narrowest, and the respective solidifications progress toward both end parts from the almost center portion of the cavity 16.  Thus, the development of the shrinkage hole in a column can be restrained by giving the solidification the directivity.
