Abstract: PURPOSE: To provide an active substance donor for affording an active substance (a drug or the like) to a contact body (a human body or the like) which can adsorb or absorb the active substance, comprising one or more layers of a porous membrane and a liquid containing a nonvolatile active substance filled in said membrane.  
     CONSTITUTION: The active substance donor is constituted from porous membrane 12 having numerous pores 11 distributed entirely and uniformly therein and liquid 13 containing an active substance filled in said pores 11. Herein a pore diameter of said pores 11 is 10μ or below, pref. 0.1W5μ practically and a thickness of the membrane 12 is about 10W500μ, pref. 50W300μ practically. A content of the active substance in the liquid containing said active substance is pref. 0.1W10wt.%. Said donor is used in dosing an active drug all over the body or locally by contacting with a skin or a mucous membrane of the body or in extincting a harmful small animal or inhibiting propagation thereof by arranging at an arbitrary place to induce said animal to be contacted with said donor. In addition, the donor can be used in providing an active substance to wood or a rust-inhibiting agent to a metal surface.

Title: Wide band amplifier for identifiable reproducing repeater
Inventor: YAMAMOTO TAKUJI
IPC: H04B10/29
Filed: 1999-01-11
Abstract: PROBLEM TO BE SOLVED: To keep optimum an eye margin at an identification point by fixing the value of a low band cutoff frequency to a closed loop gain so as to follow the change speed of a DC component fluctuation based on short-time loss increase but not to follow the change speed based on a transmission code pattern density change. SOLUTION: Corresponding to a change in a DC gain μo of a main signal amplifier circuit 10 corresponding to a transmission line loss, βo (DC gain of feedback amplifier circuit) of a DC feedback circuit 40 is changed to be βo=fc (low band cutoff frequency of closed loop gain)/μof1 (high band cutoff frequency). When the DC gain of the main signal amplifier circuit 10 is increased corresponding to the increase of the transmission line loss, by decreasing the DC gain of the DC feedback circuit 40 just for the same quantity, the opened loop DC gain μo×βo is kept at a fixed value fc/f1. Therefore, a 0dB crossing frequency fc of the opened loop gain, namely, the low band cutoff frequency fc of the closed loop gain is also kept at the fixed value although the DC gain μo of the main signal amplifier circuit 10 takes a great value.

The treating gas is thereafter supplied into the passages in the shafts 5 and while the shafts 5 are rotated, the treating gas is released from the top end of each shaft 5 into the molten metal, thereby removing the gaseous H2 and nonmetallic inclusions in the molten Al. The supply of the treating gas and the rotation of the shafts 5 are stopped upon finishing of the treatment, then the body 4 is risen and the shafts 5 are taken out of the vessel 1 to prevent consumption of the shafts 1. While the body 4 is kept risen, the body 3 is moved along the rails 2 to the position deviating from right above the vessel 1 to avoid interference of the operation by the shafts 5 in the stage of maintaining and inspecting the vessel 1.

Title: Operation controller for ventilator
Inventor: KOBA YOSHITAKA
IPC: F24F11/02
Filed: 1997-01-13
Abstract: PROBLEM TO BE SOLVED: To improve comfortableness and energy saving capacity by specifying ordinary ventilation which performs a ventilation without heat exchange between outside air and room air with a heat exchanger by a specified formula when the room temperature is higher than the set room temperature and also, higher than the temperature of outside air. SOLUTION: A bypass path 17 is closed and outside air moving through an air supply path 15 is passed through a heat exchanger 4 to be supplied to the room side from an air fan 2. The room air moving through an exhaust path 16 is passed through the heat exchanger 4 to be discharged to the outdoor side from an exhaust fan 3. When the air passes through the heat exchanger 4, a heat exchange is performed between the outside air taken into the room side and the room air discharged to the outdoor side. In this manner, so-called heat exchange ventilation is accomplished. On the other hand, the bypass path 17 is opened and the outside air or the room air is supplied or discharged directly without any heat exchange between both with the heat exchanger. In this manner, so-called ordinary ventilation is accomplished by the formulas I and II.  The condition of the formula I is room temperature > set room temperature and room temperature > temperature of outside air and that of the formula II is room temperature < set room temperature and room temperature < temperature of outside air.

Abstract: PURPOSE:To assure the stable control to the amplitude fluctuation of an AC component for a gain controller which extracts the AC component given from a photoelectric microscope, etc., by carrying out a division or multiplication with use of a DC signal corresponding to the amplitude of the AC component of an input signal. CONSTITUTION:An input signal Ei is supplied to a detecting circuit 1 via an AC amplifier 3, and the circuit 1 delivers the DC voltage (P-P voltage) in accordance with the voltage ranging from a peak to another peak of the AC signal component. A setting circuit 2 delivers the voltage proportional to the P-P voltage in case when the P-P voltage is more than a prescribed value, e.g. the value corresponding to the noise component contained in the signal Ei, and delivers a certain level of voltage corresponding to the set voltage when the P-P voltage is less than the prescribed value. The output of the circuit 2 is supplied to a denominator input terminal D of a divider 5. On the other hand, the output of the amplifier 3 is further amplified or attenuated 4 to be supplied to numerator input terminal N. A signal Eo having the amplitude kept at nearly a constant level at all times can be obtained at the output of a divider 5. And the application of the gain control can be excluded to the noise contained in the input signal.

Abstract: PURPOSE:To avoid the amount of crosstalk between four-terminal input and output terminals, by setting a differential amplifier output so that signals from a 4-terminal input to 4-terminal output terminals are in opposite polarity to the output. CONSTITUTION:The circuit consists of a 2-wire output terminal 2, a summing amplifier 3 from the terminal 2 to a 4-wire output terminal 4, an amplifier 6 transmitting 4-wire input signals with a low output impedance, a 4-wire input terminal 5, a 2-wire impedance matching resistor 7, and a differential amplifier detecting a voltage across the resistor 7, and the output of the differential amplifier 8 is inputted to the amplifier 3.

Filed: 1991-01-18
Abstract: PURPOSE:To reduce color slurring or the like by sharpening a waveform characteristic of a chroma signal in the state of high contrast. CONSTITUTION:A contour addition circuit 12 generates a contour addition signal from a luminance signal. The signal is inputted to a post-stage high pass filter 13, from which a contour signal is extracted and inputted to a clamp circuit 14, from which a contour signal subjected to DC clamp to a reference potential Vs is outputted. Thus the contour signal generated by a contour signal generating means 2 is inputted respectively to 1st and 2nd slice circuits 3,4. The circuit 3 extracts a portion of the contour signal in excess of a 1st reference potential Vs+alpha and the circuit 4 extracts a portion of the contour signal less than a 2nd reference potential Vs-alpha. In order to slice the contour signal, the noise component is eliminated so as to be not in response to a weak or medium contrast border thereby mainly improving an unsharpened waveform of the chroma signal at a strong contrast border.
