Abstract: PROBLEM TO BE SOLVED: To simply and easily obtain a styrene polymer excellent in flowability, machanical strength and heat resistance and having a narrow molecular weight distribution by using a specified polymerization tank, a form of polymerization, polymerization conditions, etc., in polymerizing a styrene compound. SOLUTION: This process for producing a styrene polymer by polymerizing a styrene compound in one or more steps, wherein the following means is used: the first-step polymerization is effected at 110-160 deg.C to a conversion in the first step of 40-80wt.% by adding at least one sulfide compound having a dithiocarbamate group, an aryl group, etc., in an amount of 50-5,000ppm by weight based on the styrene compound to the polymerization system through a continuous bulk polymerization process using a complete mixing agitating polymerization tank. This provides a polymer having characteristics satisfying the relations of the formulas 1.0<Mw /Mn <2.0 and 1.0<Mz /Mn <3.4 (wherein Mw is weight-average molecular weight, Mn is number-average molecular weight, and Mz is Z average molecular weight).  Any of reactor can be used in the second and later steps so far as a complete mixing agitating polymerization tank is used in the first step.

IPC: C04B41/52
Filed: 1989-03-24
Abstract: PURPOSE:To prevent a fall of a rock, etc., due to areation with appearance of a rock face of a slope remaining intactly by covering the rock face of the slope with a resinous transparent paint film after a room temperature setting copolymer solution is sprayed on and applied to the rock face of the slope. CONSTITUTION:A room temperature setting copolymer solution, in which a principal chain is composed of carbon - carbon coupling, a side chain has group of 0.5-10weight% and hydrolysis tendency silane group of 0.4-7.5weight%, and having molecular weight of 3,000-50,000 is applied to a rock face of a slope, and then the rock face of the slope is covered with a transparent paint film. In this case, when a large crack exists on the rock face of the slide, the crack is filled with a normal composition substance in which water is blended with a mixture of a cement substance, aggregate, and synthetic high polymer emulsion, and then similarly the rock face of the slope is covered with a resin tendency transparent paint film. This enables infiltration of rainwater, etc., into the rock face of the slope to be prevented for a long time, and also occurrence of new cracks to be prevented.

Title: Remote monitor and controller for distribution line
Inventor: HAYASHIDA NAOTO
IPC: H02J13/00
Filed: 1989-03-24
Abstract: PURPOSE:To prevent an accident, where an error 'OFF' command is transmitted by the speeding of a program and a section switch is opened to cut OFF electricity by making the delay time of a delay circuit longer than the period of time until said speeding is detected by a speeding monitoring circuit and a microprocessor is initialized. CONSTITUTION:When the period of time from the beginning of the speeding of a program until initialization is expressed by T1 and the delay time T2 of a delay circuit 4 is set to T1<T2, the output from a storage circuit 2 outputs information before the speeding of said program to the outside because the information of a microprocessor 1 during the speeding of the program is delayed by a delay circuit 4. When the microprocessor 1 is initialized, information in the delay circuit 4 is eliminated so that said information before the speeding is read from the storage circuit 2 after said initialization and a section switch 3 is maintained at the state before said speeding.

Abstract: PROBLEM TO BE SOLVED: To restrict electromigration(EM) over the whole wiring by providing a folded structure wiring, and setting the length of the wiring of a non-folded part to that not exceeding critical length specified applied current density through the wiring. SOLUTION: When a wiring includes parts each having different widths and folded parts, those parts demonstrate a substantial dam effect for atom flow fluxes, the same effect is obtained when the wiring is divided, and the effect is particularly obvious when a ratio of the amount Δ of wiring displacement in the width direction with respect to the wiring width W is 0.4 or more in the adjacent non-folded parts Lp through the folded part, and the effect is further obvious when the ratio is 1.5 or less. Accordingly, the length of tire non-folded part is set to be less than a critical length defined by cut-rent density actually applied. As a result, EM is restricted over the whole wiring.

Abstract: PURPOSE:To contrive uniformization of the necessary wire extension length by detecting respectively the contact of a nozzle and base plate, and the wire and base plate by applying a voltage between the nozzle of a welding torch and the base plate, then by applying a voltage between the wire and base plate. CONSTITUTION:A voltage is impressed between a nozzle 1 and base plate 3 by pulling in a wire 2 after positioning the nozzle 1 of a welding torch at the adequate distance of the above of the base plate 3. The voltage is then cut OFF by detecting a nozzle touch signal when the nozzle 1 and base plate 3 are abutted by moving the nozzle 1 to the direction of the base plate 3. A wire touch sensor is in succession made by impressing a voltage between the wire 2 and base plate 3 after pulling back the nozzle 1 by a fixed distance L from the base plate 3. Thereafter, the voltage is cut OFF by stopping the feeding of the wire 2, when the contact of the wire 2 and base plate 3 is detected by sending out the wire 2 slowly in the base plate 3 direction. The wire extension length can thus be uniformized.
