Title: Biaxial stretching of poly(4-methylpentene-1) film
Inventor: NIIZAWA MASAYUKI
IPC: B29C55/14
Filed: 1985-04-03
Abstract: PURPOSE:To provide a method of realizing the high draw ratio progressive biaxial stretching of poly(4-methylpentene-1) (PMP) without developing uneven stretching and breakage of film by a method wherein unstretched film made of resin mainly consisting of PMP is laterally stretched and, after that, longitudi nally stretched at the respective specified temperature. CONSTITUTION:Homopolymer of PMP, copolymer consisting of PMP as main component and another alpha-olefin as copolymeric component, a mixture of PMP and polyalpha-olefin such as polyethylene, polypropylene or the like are preferable as the resin mainly consisting of PMP. Firstly, unstretched film made of resin mainly consisting of PMP is laterally stretched at a temperature ranging film 130 deg.C or higher to under the melting point of the film with the draw ratio of 300% or more. Secondly, the resultant film is longitudinally stretched at a temperature ranging from 100 deg.C or higher to under the melting point of the film with the draw ratio of 300% or more. Because PMP is progressively and biaxially stretched as mentioned above, the satisfactory stretching is realized. Consequently, the obtained film has excellent mechanical properties as biaxially stretched film and no unevenly stretched portion.

Thereafter, the liquid is treated in an active sludge disposer 2. The disposed water is introduced into the first reaction vessel 3. In the vessel 3, the water is adjusted at pH4W6 by the addition of an acid 9, and a ferrous salt 10 is added, agitated and reacted with the water. After the reaction is completed in the vessel 3, the liquid is introduced as such, without separating precipitated cyanoferrate complex salt, into the second reaction vessel 4. In the second reaction vessel 4, the liquid is adjusted at pH6W9 by the addition of an alkali 11, and a ferric salt 12 is added and reacted with the liquid to precipitate suspensoids. Thereafter, a high molecular flocculant 13 is added to the liquid, if necessary. Flocks are formed in a line mixer 5, and separated in a sedimentation pool 6.

The detection magnetic field of the element 2 becomes intense by magnetism gathering effect when the chopper 1 comes close, but becomes weak when the chopper 1 moves away. The output signal of the element 2 is the AC signal with the vibration period of the chopper 1, so a fine magnetic field can be detected.

IPC: H03K5/13
Filed: 1987-03-25
Abstract: PURPOSE:To obtain a target multiple signal at all time by generating the magnification signal based on the outputs of plural delay circuits. CONSTITUTION:Input signals undergo the delay circuits 4-1-4-n and are subjected to different delays therein, then inputted to a selector 3 from respective connection parts. In the selector 3, either one of the inputted signals in accondance with an output from a duty decision circuit 5, and the result is inputted to an exclusive OR circuit 8, so that a multiplied output signal is outputted from its output terminal 2. The duty decision circuit 5 detects the duty of an output signal from the circuit 8. And if the time during which the level of a pulse is in a high level is shorter than a time when in a low level, the selector 3 inputs an input signal of a longer delay time to the circuit 8, but if the high-level time is longer than the low-level time, an input signal of a shorter delay time is inputted to the circuit 8. As a result, a stable signal free from the incluence of temperature variation or variance due to manufacture can be obtained.

Abstract: PURPOSE:To improve the inference process efficiency by showing a fact of possibility to an operator so that a fact is specified by the operator. CONSTITUTION:An inference control part 3 defines a received fact to be proved as a hypothesis and extracts a production tule including said hypothesis in a conclusion part out of a rule memory part 1 and checks whether the hypothesis is concluded or not as a fact. If the fact memory part of a dynamic data memory part 7 does not include a fact with which a conditional part is concluded as a fact, it is decided whether the fact can be proved or not by another production rule. If this proof is impossible, the confirmation of a fact is questioned to a user through a display part 4 in terms of the fact of possibility estimated as the conditional part. Then the user registers the fact of possibility shown by a user input part 5 to a user input memory part 6. At the same time, the inference process is advanced by means of said fact.

Title: Method for controlling movement of pipe for ejecting refractory material
Inventor: HONDA MASAMICHI
IPC: B05D1/02
Filed: 1982-04-27
Abstract: PURPOSE:To accurately, certainly and automatically control the motion of an ejecting pipe, by detecting the rotation number of the ejecting pipe with a tachometer, and controlling a mechanism for moving the pipe back and forth and/or a mechanism for driving a piston. CONSTITUTION:When an amount of a refractory material to be injected through an ejecting pipe 1 into a tapping hole A is increased, the rotation torque of the ejecting pipe 1 is also increased. If said increase exceeds a preset value, the rotation number of a hydraulic motor 5 is reduced. This reduction is detected by a means 70 for detecting a rotation number, and the detected signal is dispatched to an electromagnetic valve 57 to control the back and forth movement or stop of the second hydraulic cylinder 10, i.e. the ejecting pipe 1, and/or a mechanism for driving a piston. Consequently, the motion of the pipe can be automatically, accurately and certainly controlled to form excellent lining.
