Title: Production of chloromethylated polymer
Inventor: TADA AKIRA
IPC: C08F8/24
Filed: 1983-12-26
Abstract: PURPOSE:To reaction mixture between particles of styrene polymer and chloromethyl methyl ether is combined with hydrogen chloride and distilled to produce the titled polymer with industrially advantage so that the remaining ether is effectively recovered without decomposition. CONSTITUTION:(A) Particles of styrene polymer are allowed to react with (B) chloromethyl methyl ether in the presence of an organic solvent such as pentane and a catalyst. The resultant reaction mixture is combined with (C) hydrochloric acid and distilled to recover the excessive amount of component B and/or its decomposition products as well as the objective polymer. The amount of component C is preferably 1-5 times the molar amount of component B and the use of hydrochloric acid as a component C is preferred, because it deactivates the catalyst in the reaction mixture and prohibits the component B from being hydrolyzed.

Abstract: PURPOSE:To stabilize a power amplifier element stably for a long time and to attain also unmanned motion by providing the titled device with a negative feedback circuit for holding an optimum output value determined by a control circuit stably. CONSTITUTION:A CPU body 14 varies a reference voltage generator 4 while monitoring the output of a detector 5' to search the range of stable operation voltage of a load 9 and sets up a reference voltage 4 to the stop voltage.

Filed: 1989-09-26
Abstract: PURPOSE:To lessen the number of output terminals and to enable simplification of construction of an output section selecting circuit by a method wherein output electrodes in a group so provided as to divide a resistance layer into a number of sections are separated into a plurality of sets and a common output terminal is provided for each set. CONSTITUTION:When output terminals in a group are separated into (T1, T3, T5) and (T2, T4, T6) and taken out collectively from common output terminals Ta and Tb respectively, an image position detection characteristic obtained in this case is as shown in the figure 1B. An image position corresponding to an output value e0 obtained herein can not be specified from X1 to X5. Accordingly, a bias layer C is also constructed to be a resistor and output terminals TC1 and TC2 are taken out from the opposite ends thereof. Thereby an output characteristic as shown in the figure 1D is obtained. Now, when it is assumed that an output obtained by computation from the terminals TC1 and TC2 is (ec), it is found that the position of incidence of light is Xc and that it is located in a section between the terminals T4 and T5 of the figure 1A. An image position X4 between the terminals T4 and T5 can be determined with high resolution from the output value e0 obtained by computation of an output current from the terminals Ta and Tb.

IPC: B65G47/68
Filed: 1994-10-17
Abstract: PURPOSE:To provide a branching-joining conveyor equipment by which conveyance objects can be always suitably branched off or joined together regardless of the size of a shape. CONSTITUTION:When the roller axes 19 are formed in an orthogonal shape to a conveying passage 9, conveyance objects 60 can be carried to the lower part by roller 16 groups without being sorted out. When the conveyance objects 60 are sorted out, an angle changing device 30 is actuated, inclinations of the roller 16 groups are respectively separately changed, that is, the upper part side inclination is made small, and the inclinations are inclined by making them gradually large. Branching operation is performed by gradually approaching the conveyance objects to the side up to a large quantity from a small quantity while gradually changing the direction to a large angle from a small angle. The conveyance objects 60 can be always suitably branched off out of relation to the size of a shape by exerting a sufficient branching action without early (suddenly) exerting the branching action. They can be always suitably joined together by an inverse action out of relation to the size of a shape.

Title: Propeller for ship
Inventor: NISHIYAMA YUKIO
IPC: B63H1/26
Filed: 1984-11-26
Abstract: PURPOSE:To improve the resistance of a propeller to cavitation erosion and corrosion by forming Cr plating of a specified thickness on the forward and backward sides of the body of the propeller. CONSTITUTION:Cr plating of >=100mum thickness is formed on the forward and backward sides of the body of a propeller for a ship so that the sides are coated entirely or partially with the plating. It is preferable that the Cr plating is composed of two or more layers.
