Abstract: PURPOSE:To cake asbestos and to make it harmless by forming a basic glass coat on the surface of the asbestos by treatment with an aq. soln. of an alkali metal silicate and drying, dissolving the acicular asbestos by acid treatment and forming a mass. CONSTITUTION:The surface of waste asbestos is coated with an aq. soln. of an alkali metal silicate such as sodium silicate or potassium silicate by spraying or other method and the soln. is dried and solidified to form a basic glass coat of about 0.1-100mum thickness on the surface of the asbestos. This asbestos is then treated with an aq. soln. of an acid such as sulfuric acid or phosphoric acid to dissolve the acicular asbestos and a mass is formed. The concn. of the acid soln. is about 1-100wt.%, the pH is about <=3 and the acid soln. is sprayed or applied by an amt. (weight) about 0.1-1.5 times the amt. of the asbestos. The acicular crystals of the asbestos are vanished and the asbestos is caked and can be made harmless.

Filed: 1979-09-27
Abstract: PURPOSE:To enable stabilization of the film diameter and high speed take-up of the film in the manufacturing step by prolonging the distance and time required for the contact of the cylindrical film with cooling water thereby to improve the cooling effect. CONSTITUTION:A film 2 extruded from a mouth piece 1 is expanded in diameter by air blasted from a blasting pipe 3, and cooled with cooling water on the upper step cooling ring 41, and lower cooling ring 42 of a cooling device 4. The cooling water in a pressure reduction chamber 44 is supplied through a water supply pipe 46' and a part of the cooling water is exhausted through an exhaust pipe 47', and the major part thereof is sucked up by means of a pump 6 as shown by arrow A. The larger the pressure reduction water suction function of the pump 6, the better. If the pump 6 has a function more than the difference A between the level of water stored in the inner side reduction chamber and the level of water on the upper ring 41, the film 2 is taken up downward while pressing and sealing cooling water on the outer peripheral surface, and hence variation in the diameter of the film 2 becomes small, and the time required for contacting cooling becomes large, so that the high-speed take-up of the film 2 becomes possible.

Inventor: COURT AGNES
IPC: F16K7/18
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To couple a material having flexibility to a material having rigidity so that operation of a hinge is practicable. SOLUTION: For example, a ventilation device 30 to ventilate the internal part of an automobile contains a frame 32 molded out of a thermoplastic material having rigidity. The frame 32 is provided with a side wall, for example, 32A, for forming an opening, end walls 32C and 32D, and a partition wall 32E. The opening is controlled by flap valves 38 and 40. Since the flap valves 38 and 40 are molded in their positions by using a material having flexibility and are not suited for a material having rigidity, the valves are not adhered to the frame 32 at a molding process. A material for the flap valves 38 and 40 has a series of holes in which studs 58 and 60 are protruded. The studs 58 and 60 have an expansion head part to form hinges 42 and 44 and the flap valves 38 and 40 are bent between an opening position and a closing position.  In the closing position, the flap valves 38 and 40 seal respective valve seats 50 and 52.

Filed: 1982-07-21
Abstract: PURPOSE:To permit the maximum torque operation by a method wherein dynamics between an ignition timing and a crank angle, in which the probabilistically varying pressure in a cylinder becomes maximum, is considered to control the ignition timing most properly. CONSTITUTION:In case the ignition timing is regulated to bring the combustion of an engine 8 into MBT (Minimum advance for Best Torque), the estimated value xi' of the proper dimension of the amount xi of a condition parameter, representing the dynamic internal condition of the engine, is obtained at first based on a probabilistic dynamics model between the ignition timing IT and a crank angle thetapmax in a condition observing device 9 (Karman filter). Subsequently, a value, obtained by multiplying the estimated value xi with a gain ki in a gain block 10, is applied to the ignition timing by feedback to control the engine 8. According to such manner, the value thetapmax may be regulated to a predetermined value upon transition and the maximum torque operation may be effected, if the most proper control of the dynamics is effected upon transition.

Title: Biasing method of self-oscillator
Inventor: KOBAYASHI YASUMI
IPC: H03B5/12
Filed: 1984-06-18
Abstract: PURPOSE:To prevent destruction of elements due to a surge voltage of -Ldi/dt generated from the inductance of a circuit and the sudden change of current by increasing the value of a fixed bias after growth of oscillation to make it easy to flow a main circuit current and keeping a switching element turned on even when self-oscillation is stopped. CONSTITUTION:A voltage +DC of a power supply circuit passes a resistance RC and is divided by a variable resistance VR2, and this divided voltage is supplied through a diode D2 and an OR circuit consisting of diodes D1 and D2; and a power supply circuit (i) consisting of a resistance VR1 and the diode D2 is preferred at a start time with respect to bias, and a power supply circuit II is preferred in accordance with the rise of the voltage +DC. Since the circuit is fixed to the bias voltage for a certain period (several ms at most) even if oscillation is stopped not to output a detection signaly by load short-circuit, a transistor F is in the conductive state, and the variation of di/dt is small, and thus, it is possible that the over-voltage due to E=-Ldi/dt does not exceed the dielectric strength of the transistor F.
