Abstract: The signal-processing circuit of the present in­vention, more particularly the gain-controlled amplifier circuit, comprises a MOSFET (metal oxide semiconductor field-effect transistor) (2l), and an NPN bipolar tran­sistor (22) cascade-connected to the MOSFET (2l). The gain-controlled amplifier circuit amplifiers the signal supplied to the gate of the MOSFET (2l), with the gain corresponding to the voltage applied to the base of the NPN bipolar transistor (22). The circuit can generate an output signal at one end of the emitter-collector path of the NPN bipolar transistor (22), said output signal containing negligibly small distortion com­ponents; in particular, negligible third distortion components.

Abstract: A liquid flow regulator (10) has a housing (11, 12) including an axial bore (13), an inlet (14), an outlet (15) and a plurality of axial grooves (17) opening endwise of the inlet (14) and laterally of the housing (11, 12) into the bore (13). The grooves (17), which have different axial lengths, taper axially so that the cross-sectional area of each groove (17) gradually decreases from the inlet (14) to nothing at a point where the groove (17) merges with the bore (13). An elastomeric sock (19) fits within the bore (13). A plunger (21, 22) for expanding the sock (19) radially outward into sealing engagement with the housing (11, 12) adjacent the bore (13) is axially movable within the bore (13). Flow through the grooves (17) and the bore (13) is regulated by the axial position of the plunger (21, 22) and the minimum cross-sectional area of the tapered, axial grooves (17) at the axial location where the sock (19) seals the bore (13). Axial adjustment of the plunger (21, 22) sequentially opens and closes passage from the grooves (17) through the bore (13) to the bore outlet (15). The upper end of the plunger (21, 22) is provided with threads (49 for engagement with internal threading (50) in a passageway so that rotation of the plunger (21, 22) adjusts its axial position for control of the flow. The connection between the plunger and passageway threads is flexible so that the threads can be flexed out of engagement with each other when it is desired to axially and non-rotatively move the plunger to quickly place the regulator in a fully open or fully closed condition.

Abstract: There is disclosed a method for separating alpha-l-­proteinase inhibitor (also known as alpha-l antitrypsin) from an aqueous solution of plasma proteins, especially from Cohn Effluent II & III and Cohn Effluent I. The method includes the steps of first treating the aqueous solution to lower the concentration of salts therein and, optionally, its alcohol content, contacting the resulting solution with an anion exchange resin having selective affinity for alpha-l-proteinase inhibitor to selectively bind the alpha-l-proteinase inhibitor and allow unwanted plasma proteins to elute through the resin, displacing the alpha-l-proteinase inhibitor from the resin and recovering the same.

Abstract: Thru-holes are drilled in a printed circuit board panel having alternating dielectric layers and electrically conductive layers. A water soluble dry film lubricant sheet is placed adjacent an electrically conductive outer layer of the panel prior to drilling thru-holes through the panel with a rotary drill. The drill surface is lubri­cated while forming a clean thru-hole from contact between the drill and the lubricant. The dry film lubricant gener­ally may comprise a water soluble lubricant hardened to a solid or semi-solid dry film-form and impregnated in a carrier such as a porous paper sheet. In one embodiment, the dry film lubricant includes a water soluble lubricant such as dipropylene glycol, a non-ionic surfactant, and a wax-like hardener. Following drilling of the thru-holes, the dry film lubricant sheet is removed, and the thru-­holes can be rinsed in an aqueous alkaline solution. The thru-holes are then plated with an electrically conductive metal for forming electrical contacts between the metalized thru-holes and the electrically conductive layers of the panel. The dry film lubricant extends drill life and produces a clean thru-hole that prevents epoxy smear and avoids the prior art use of harsh chemical treatment follow­ing drilling to otherwise remove dielectric smear or fibers that might extend into the thru-hole and disrupt the continuity of the later-formed electrical contact.

Abstract: A threshold switching device for protecting an electrical circuit from an overvoltage comprises a switching element formed from a chalcogenide glass and a pair of electrodes that are in contact with the com­position. When the circuit experiences an overvoltage transient, the switching element will switch to its low resistance state to pass the electrical current to ground and then revert to its high resistance state. 
     The switching element includes an indium layer or an indium containing layer between the switching ele­ment and at least one, preferably both electrodes. The presence of the indium layers improves the adhesion of the electrodes and/or reduces the electrical contact resistance between the chalcogenide glass and the electrodes and thereby increases the amount of electri­cal energy that may be passed through the device during a voltage transient before the device latches in its low resistance state.

Abstract: A developing method for converting an electrostatic latent image on the surface of an electrostatic latent image holder (5) into a visible image by arranging the electrostatic latent image holder (5) for holding the electrostatic latent image thereon and a toner conveyer (l) for conveying non-magnetic one-component type toner (4) thereon an extremely small space apart from each other; applying the non-magnetic one-component type toner onto the toner conveyer; and transferring the toner (4) to the electro­static image holder (5). The method satisfies the following requirements: the aforesaid developing agent is composed of non-­magnetic type toner; the frictional charge quantity relative to the surface of the non-magnetic type toner is +30∼l00µC; and fluidity is 5 g or less in terms of the toner amounting to 20 g but remaining on a l00-mesh sieve after it has been vibrated a rate of 3,000 V.P.M. and an amplitude of l mm for 30 seconds. The non-magnetic one-component type toner may be positively charged; the non-magnetic one-component type toner at least contains resin and a colouring agent, the resin satisfying the following requirements: the glass transition point is over 50°C; the softening point is within the range of 110°C-160°C; and the frictional charge amount relative to the surface area is within the range of 25∼l50 µC/m². The non-­magnetic one-component type toner may be prepared by treating the surface of toner containing binder resin whose glass transition   point is over 50°C and whose softening point is within the range of ll0∼l60°C and a colouring agent with a silane coupling agent having an amino group. 
     According to the above method, development fog and the scattering of the toner are prevented so that a visible image of good quality can be formed.
