Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To provide a polymer coagulant which has high ability to clarify a suspension and enables the reduction of the water content of a cake being formed, by sulfonating a styrene polymer. SOLUTION: A styrene polymer containing 60wt.% or less of another polymer such as polyphenylene ether, polycarbonate, polyphenylene sulfide, polyethylene terephthalate or the like is mixed, relative to 1 mole of an aromatic ring unit contained in the styrene polymer, with 0.5 to 2.0 mole of a sulfating agent and 0.01 to 2.0 mole of a Lewis base, together with a solvent such as a 1-2C aliphatic halogenated hydrocarbon, an alicyclic hydrocarbon and the like. The resulting mixture is allowed to react at a temperature of 0 to 100 deg.C for 10min to 10hr, so that the styrene polymer is sulfonated and a polymer coagulant having a weight average molecular weight of 150,000 to 600,000 is obtained. To a waste water, are added this polymer coagulant and, a non-ionic and or anion acrylamide polymer or a cationic polymer, to thereby clarify the waste water.

Title: Reinforced frame of pier and its connecting method
Inventor: ISHIBASHI TADAYOSHI
IPC: E04G23/02
Filed: 1995-10-03
Abstract: PROBLEM TO BE SOLVED: To work without being affected by working environment and increase workability by connecting a recessed joint and a protruded joint to members to be connected beforehand, opposing the recessed joint and protruded joint to each other at site, and pressing or inserting them by using a spring action. SOLUTION: Those steel plates 2 to which a recessed joint 10 and a protruded joint 20 are connected beforehand are opposed to each other by a working vehicle such as a crane at site so that they surround a pier, and the protruded joint 20 is inserted in parallel with the axial direction of the joint through the opening of the recessed joint 10. Also the opening is expanded by the spring action of the recessed joint 10, and the protruded joint 20 is inserted. When the protruded joint 20 is inserted completely into the recessed joint 10, the opening is recovered by the spring action. By this, the hooking protruded parts 10a and 10b of the recessed joint 10 are hooked to the extended protruded parts 20a and 20b of the protruded joint 20 and, therefore, even if a parting force acts on them, they will not be extracted completely.  Thus working can be performed without being affected by working environment, and the workability can be increased.

Filed: 1985-11-15
Abstract: PURPOSE:To make a signal alone at the time of breakage transmittable to a signal processing part, besides no effect of noise, as well as improve reliability in tool breakage detection, by installing a false breaking signal generating device, a signal processing device having a dead zone, and a sensitivity setting device. CONSTITUTION:A false breaking signal generator 4 is attached to a drill setting part of a drill supporting part 3 in a drilling machine, while an AE sensor is attached to the side of this drill supporting part 3 and it is connected to a dead zone amplifier 7 by way of an analog switch 6. The set AE signal is transmitted from the false breaking signal generator 4 and detected by the AE sensor 5, but this signal contains a rotational noise out of a bearing. When a peak value of this bearing noise is set to Vo and a peak value of the false breaking signal to Vp, respectively, a dead zone to Vo is set to the head zone amplifier 7 at a control circuit 8 whereby such a signal that removes the bearing noise is secured, and this signal is amplified and restored to the original false breaking signal, thus reliability in tool breakage detection is sharply improvable.

An alarm unit 4 is arranged, and when a signal from the signal processor 3 becomes, for example, 18% or less, an alarm is issued. Thereby, a wide range of oxygen concentration can be measured without being influenced by a local change in the oxygen concentration.

The light past the light transmitting part of the device 12 passes through a distributed index lens array 13 and forms an image 15 of the device 12 on a photosensitive drum 14. The image 15 is bright only in the position corresponding to the foam in the light transmittable part of the device 12 if the device 12 uses the opaque liquid and foam. Conversely, the image is dark in the position corresponding to the granular material if the device 12 uses the transparent liquid and foam or the transparent liquid and opaque granular material.

IPC: G06F13/00
Filed: 1987-10-15
Abstract: PURPOSE:To enable an information processor itself to perform an IPL (initial program loading) action at a high speed by adding a nonvolatile memory into the information processor to store an IPL program. CONSTITUTION:A program memory 12 stores previously a program to be stored in a control memory 11 at IPL before attachment of the memory1 3. When an IPL job is carried out, a control means 14 reads out the contents of the memory 12 based on an IPL program stored in an IPL control memory 13 and stores them in the memory 11. Then the means 14 carries out the contents of the memory 11 in place of the memory 13 when the IPL job is through. Thus the memory 12 is set into an information processor to store the program to be loaded into the memory 11 at IPL. In such a constitution, no SVP (service processor) nor external auxiliary memory can be omitted and the information processor itself can perform a high-speed IPL job.
