Abstract: PURPOSE: An automatic gain control method and a circuit thereof are provided which can reduce a setup time that it takes to allow an automatic gain control to be stable and is not sensitive to an instantaneous variation of input signal level. CONSTITUTION: An automatic gain control apparatus includes: an IF amplifier(100) for amplifying an IF signal according to a gain control voltage; a modulator(110) for modulating an amplified IF signal to generate a signal having a video component and a frequency component twice as much as that of IF carrier; a low-pass filter(120) for removing high frequency components from the signal inputted from the modulator and outputting a video signal; a comb filter(130) for dividing the video signal into a color signal and a luminance signal; a sync-signal detector(140) for detecting a sync signal from the luminance signal; an amplitude detector(150) for detecting an amplitude of the video signal during a sync period; a transconductance amplifier(160) for variably amplifying a difference voltage between amplitudes of the video signal and a reference signal; a capacitor(170) for accumulating the output voltage from the transconductance amplifier(180) to output a charged voltage as the gain control voltage to the IF amplifier; and a microcomputer for controlling the gain control signal to the transconductance amplifier, such that transconductance amplifier has a gain less than that before being stable. Therefore, by varying the amplifier gain according to the degree of amplitude variation of input signal, the apparatus reduces a setup time that it takes to allow an automatic gain control to be stable and is not sensitive to an instantaneous variation of input signal level.

Filed: 1997-03-20
Abstract: PURPOSE: Replicated polymeric micro-structures have been used in the fabrication of optofibre wave guide connections, with the intention of simplifying the production of such connections, and therewith greatly reduce manufacturing costs. CONSTITUTION: Fabrication is commenced from a silicon chip (1) in which there have been etched grooves (2) whose cross-sectional shape has been adapted to accommodate wave guides, such as optofibres (3). Firstly, the silicon chip (1) is replicated by plating the silicon chip with nickel, for instance. The replication then serves as a model for producing a plastic copy of the silicon chip. This method of manufacture is able to produce wave guide accommodating grooves (2), such as optofibre (3) accommodating grooves, to a very high degree of accuracy. Furthermore, the method provides a high degree of freedom in the configuration of the grooves (2), and also enables branched grooves for receiving branched fibres to be produced. The wave guide connection can then be used with a wave guide, such as an optofibre, together with a light transmitter or light receiver.

Title: Anti-viral, anhydrous, and mild skin lotions for application to tissue paper products
Inventor: KLOFTA THOMAS JAMES
IPC: A01N25/34
Filed: 1997-05-30
Abstract: PURPOSE: An anti-viral, anhydrous, and mild skin lotion is provided to minimize or prevent a harmful effect to the tensile strength of a lotion-treated paper and a caliper while helping for maintaining the physical properties of the tensile strength and the caliper. CONSTITUTION: A lotion composition for killing such viruses as rhinovirus and influenza in addition to imparting a soft, lubricious, lotion-like feel when applied to tissue paper in amounts as low as from about 2 to about 20 % by weight, and tissue paper treated with such lotion compositions are disclosed. The anti-viral action of the lotion is due to the addition of an organic acid such as citric acid or a mixture of adipic acid, glutaric acid, and succinic acids. The solubilization of the organic acids within the lotion matrix and with the infected mucus is aided by the addition of such hydrophilic solvents as propylene glycol and polyethylene glycols. The lubricious lotions also contain a plastic or fluid emollient such as petrolatum, an immobilizing agent such as a fatty alcohol or fatty acid to immobilize the emollient on the surface of the tissue paper web and optionally a non-tonic surfactant to improve wettability when applied to toilet tissue. Because less lotion is required to impart the desired soft, lotion-like feel benefits, detrimental effects on the tensile strength and caliper of the lotioned paper are minimized or avoided. The anhydrous nature of the lotions also aids in the maintenance of such physical properties as tensile and caliper.

Filed: 1999-06-17
Abstract: PURPOSE: A pumping method is provided to achieve an improved workability by reducing work time and labor while allowing the contractile mortar to be effectively pumped, considering the height and distance of the work field. CONSTITUTION: When a cylinder rod(61a) of a lower cylinder(6a) moves backward, a suction force is generated within the lower cylinder. Thus, a weight ball valve(5a) opens a valve pipe(4a), and the contractile mortar flows into the lower cylinder through an inlet guide pipe(1). A cylinder rod(61b) of an upper cylinder(6b) moves forward so as to press the contractile mortar contained within the upper cylinder. Thus, the weight ball valve shuts off a valve pipe(4b) by the internal pressure of an upper suction pipe(2b), to thereby prevent the mortar from reversely flowing toward a lower suction pipe(2a), and a weight ball valve(5c) of an outlet pipe(3) opens a valve pipe(4c) by the pressure of the mortar. Thus, the mortar pushed through the outlet pipe is conveyed to the work field through a connection pipe(7). The lower cylinder sucks the mortar, while the upper cylinder discharges the mortar, thus preventing deterioration of pumping ability caused by contraction or reverse flow of the mortar.
