Abstract: PURPOSE:To make it possible to print a micro-patterned thin film by using a composition which consists of an indium compound and a solvent in which two or more among a small amount of tin compound, a gummy natural resinous rosin, and a terpene solvent of a high boiling point are combined together. CONSTITUTION:A composition is composed of an indium compound and a solvent in which two or more among a small amount of tin compound for adjusting a resistance value, a gummy natural resinous rosin as a tackifier, and a terpene solvent of a high boiling point, i.e., of a boiling point not less than 200 degrees Celsius with a small range of temperatures are combined together. For the indium compound and the tin compound, indium octylate which is salt of octylicacid and di-butyltin-dioctate are used, and for a natural rosin, the one principally composed of abietic acid and gummy rosins are preferred. For a terpene solvent of a high boiling point, that of a small range of boiling points is preferred, and for example, two kinds of such materials as terpineol, pine oil, sesquiturpentine, n-bornylacetate are combined together for use. Thereby a transparent conductive layer of a thin film is obtained, thereby the patterned line on which formed by offset printing is delicate and sharp.

Filed: 1981-07-10
Abstract: PURPOSE:To detect the leakage of liquid such as oils by detecting the change in the loss of the quantity of heat generated in a heating element resistor by the change in the heat conductivity of fluid. CONSTITUTION:A heating element resistor 1 is connected to one side of a bridge circuit. The bridge circuit is connected with an electric power source 5 via a transistor 8. When fluid sticks to or contacts the resistor 1, heat is dissipated therefrom, and the resistance value of the resistor 1 changes. To make the difference between the atmospheric temp. and the temp. of the resistor 1 constant, the unbalance voltage outputted by the bridge circuit is amplified with a differential amplifier 6 and the output of the amplifier 6 is applied to a transistor 8, which controls electric current until the unbalance voltage of the bridge circuit is made zero. The voltage of the resistor 3 is detected with an indicator, whereby the leakage of the fluid is detected.

Title: Method for removing backlash of continuous casting plant
Inventor: ITOU HITOSHI
IPC: B22D11/16
Filed: 1980-08-05
Abstract: PURPOSE: To remove titled backlash by subjecting motors for drive rolls drawing a dummy bar forcibly to motoring or braking operation irrespectively of actual drawing resistance.  
     CONSTITUTION: The drawing resistance generated by a slab and a dummy bar is on negative side because the gravity falling force of the dummy bar overcomes the same. A drive motor 20A for roll guides the dummy bar while making braking operation. When the next motor 20B is connected to a thyristor device 21 by a selector 23, the signal of a torque detector 26B of the motor 20B is also selected to a comparator 27. On the other hand, the motor 20A is connected to a thyristor device 22 and the motor 20B continues braking operation until the torque set value is attained. The motor 20A switches to motoring operation. Hence, compressive force acts between both ends of the dummy bar and the clatter in the coupling part of links is eleminated. Since the motors make respectively stable operations, the backlash of speed reducers is eliminated.
