Title: Coagulation of latex
Inventor: ISHIDA HISAKATSU
IPC: C08J3/16
Filed: 1982-04-09
Abstract: PURPOSE:To obtain, in good efficiency, a porous solid polymer having a uniform particle size distribution, by contacting a polymer latex with a coagulant solution in a tubular coagulator, thereby forming a highly concentrated coagulum slurry, and then diluting the slurry. CONSTITUTION:A tubular coagulator consisting of an external cylinder 15 having a length l1 and one blocked end i and an internal cylinder 16 having a length l2(l1>l2) and inserted into the external cylinder 15 on the side of end i is used. A polymer latex 17 such as a styrene/butadiene rubber latex 17 is fed into the internal cylinder 16 and a coagulant solution 18 (e.g., an aqueous sulfuric acid solution) is fed through a nozzle 13 into the external cylinder 15 to effect a coagulation reaction near the exit of the internal cylinder to form a highly concentrated coagulant slurry. Then, a diluent is fed through a nozzle 14 to dilute the slurry and the polymer solid 22 is separated in a solid/liquid separator 21 from a coagulated solution and then recovered. Further, the coagulated solution is sent to a coagulated solution tank 24 for heating with steam 23 and recirculated as the diluent.

Filed: 1988-03-15
Abstract: PURPOSE:To enable the title method to form the rest of a gate on the side of a sealing part, by a method wherein a cavity plate in which a gate groove is formed is interposed between a top and bottom forces, a side gate is formed at a position separated from the surface of a circuit board and sealing resin is cast into a cavity. CONSTITUTION:A cavity plate 3 is fixed to a recessed part 1a of a top force and a circuit board 4 is fixed to a recessed part 2c of a bottom force. A side gate 3d connecting with the side of a cavity 3a is constituted between the gate groove 3b of the cavity plate 3 and the top force 1 and a runner 2d is constituted between a runner groove 2b of the bottom force 2 and the top force 1.

Title: Semiconductor device
Inventor: YAMASHITA SHIGEAKI
IPC: H01L21/331
Filed: 1978-05-17
Abstract: PURPOSE: To increase the curvature radius of the PN junction surface and thus to avoid the field concentration when the impurity is diffused within the semiconductor substrate by drilling the hole part for diffusion to the insulator layer to be used as the mask and at the same time providing the concavity to the substrate in correspondence to the hole part of the insulator layer.  
     CONSTITUTION: SiO 2  insulator film 5 is coated on N-type Si substrate 1, and the P-type impurity is diffused from the back surface. Thus, P-type anode region 2 is formed from the buttom surface to the side surface. Then hole part 10 is drilled to film 5 in order to form gate region 3 within substrate 1 surrounded by region 2, and furthermore concavity 11 is formed within substrate 1 via the mixed acid of HF and HNO 3  and in correspondence to part 10. After this, the P-type impurity is diffused concavity 11 for a long time at the high temperatures of 1000∼1200°C, and thus depth t1 of the horizontal diffusion is made identical to depth t2 of the vertical diffusion. In such way, the curvature radius is increased for junction surface 12, thus increasing the dielectric strength.

Abstract: PROBLEM TO BE SOLVED: To provide a urinal washing system capable of flowing a proper amount of washing water in accordance with a state of use and preventing the overflow of washing water and the occurrence of clog in the urinal washing system. SOLUTION: A sensor unit 10 incorporating a pressure sensor and a signal processing circuit therein is provided upward of a trap section 5 formed in the bottom of the inside of a urinal main body 1. A tank 11 is provided to the rear side of the urinal main body, the tank 11 is connected to the trap section 5 with a thick piping 12, and the tank 11 is connected to a pressure leading section of the pressure sensor with a thin piping 13. In the case of urination, since the water level of the trap section 5 is raised to raise also the water level in the tank 11, the pressure in the tank/thin pipe 13 is raised in accordance with the water level. Accordingly, when pressure is detected by the sensor, the water level is found out, and detection can be made whether or not the urination is made besides the quantity thereof.  When the urination is made, a valve 8 is opened to supply washing water in the urinal main body through a washing water piping 7. Even if dust flows in the thick piping 12 side from the trap section 5 side, the dust is exhausted again with the decrease of the water level without being stopped up because of large sectional area.
