Title: Power amplifier circuit
Inventor: INAMI DAIJIRO
IPC: H03F3/30
Filed: 1989-09-04
Abstract: PURPOSE:To avoid a change in a through-current at non-signal state by combining a 1st current generating circuit generating a stable current at all times independently of an input signal and a 2nd current generating circuit generating a large current only at a large amplitude input. CONSTITUTION:Let a source potential of an N-channel MOS transistor (TR) 1 be V1, its threshold level be VTN, a source potential of a P-channel MOS TR 5 be V5, and its threshold level be VTP, then the TR 1 is conductive in the case of Vin-V1-VTN>0 with an input voltage Vin applied to an input terminal (a), and the TR 5 is conductive in the case of Vin-V5-VTN<0, and the TRs 1, 5 are not simultaneously conductive. A through-current at non-signal state depends on currents resulting from currents IDD9, IDD10 amplified by current mirror circuits 3, 5 respectively, and is independent of currents IDD1, IDD5. Thus, the bias voltage is independent of manufacture and temperature conditions and a through-current always stable is obtained.

Abstract: PURPOSE:To provide a spinning apparatus capable of remarkably decreasing the breakage of a spun yarn and enabling stable spinning by setting the distance between the front roller of a drafting part and the delivery roller to take-up the spun yarn to be shorter than the maximum fiber length of the supplied staple fiber. CONSTITUTION:A staple fiber tow S is passed through a back roller 1 and an apron roller 3 constituting a drafting part and delivered from a front roller 4. The tow W is introduced into a spinning nozzle 6 and ballooned with an air-ejection nozzle Na of a 1st nozzle 5a to free the tip end of the fiber constituting the surface part of the staple fiber tow S. The tow passed through the 1st nozzle 5a is false-twisted by the action of the air-ejection nozzle Nb of a 2nd nozzle 5b and the fibers of the surface part is wound around the core fiber in the untwisting of the false-twisted fiber to form a spun yarn Y. In this process, the breakage of the spun yarn Y can remarkably be decreased by setting the distance D between the front roller 4 of the drafting part and the delivery roller 7 to take-up the spun yarn Y to be shorter than the maximum fiber length of the supplied staple fiber.

SOLUTION: In a magnetic-alloy thin band 1 punched by a press, the areal occupation factor of carbons existent on its surface which is measured by an Auger electron spectroscopic method is made not larger than 5% to make preventable its seizure when subjecting it to a heat treatment. An insulation layer is interposed between the respective adjacent magnetic-alloy thin bands 1 when they are laminated to form a laminated core. This insulation layer serves as an interlayer insulator. The thickness of the magnetic-alloy thin band 1 is made preferably not smaller than 10 μm and not larger than 500 μm. Also, an arithmetic mean roughness Ra of its surface is made preferably not smaller than 1 μm and not larger than 12.5 μm, and more preferably not smaller than 0.5 μm and not larger than 5 μm.  When the numeral value of Ra falls within this scope, the interlayer seizure of the magnetic-alloy thin bands 1 are prevented, and the volumetric factor when they are laminated can be secured to make securable the characteristic obtained as the laminated core.

Abstract: PURPOSE:To prevent any inequality in the distance between a positive and a negative current collector which might be caused by repeated or long-period bending or deformation as well as any cracks in a separator which might be caused by external force or shock by dispersing a number of granular spacers in generation elements. CONSTITUTION:After exterior members 1 and 2 prepared by forming flexible macromolecular films in almost the same shape are superimposed on each other, current collectors 5 and 6 made of aluminum, copper or the like are provided on the inner sides of the exterior members 1 and 2 in desired form. Parts of the exterior members 1 and 2 are provided with windows 3 and 4 for taking out terminals before lead terminals 7 and 8 are provided in the windows 3 and 4.

Here the granular spacers 11 either consist of a resin or rubber system material or are coated with either of these materials. As a result, there is no possibility that the exterior members 1 or 2 or the current collector 5 or 6 is damaged or broken even when the battery is curved, any external shock will be absorbed by the elasticity of the spacers 11 and migration of the spacers 11 is caused only with difficulty. Consequently any breakage of a separator as well as any extreme deformation of the battery can be prevented.
