Title: Method and apparatus for coating wire with thermoplastic resin
Inventor: MATSUNO SHIGEHIRO
IPC: B29C48/06
Filed: 1985-02-20
Abstract: PURPOSE:To remove the running disturbance of a core wire in the guide hole of a nipple passing the core wire by passing the core wire through the guide hole with thermoplastic resin between the guide hole and the core wire and coating the core wire with thermoplastic resin. CONSTITUTION:Between the nipple 3 and the die 5 is mounted a guide member 14 having in the center a cavity 12 of approx. V-section which inclines at the nearly same angle as the slope surface of the tip of the nipple 3. Resin which branches and flows into a reservoir 26 forms an equal thickness around the outer circumference of the core wire A and the core wire A passes the guide hole 22 through thermoplastic resin melted between the guide hole 22 of the guide member 14 and the core wire A. By this process, the mild surface of the core wire is not scraped by the guide hole of the crosshead and therefore, the running disturbance of the core wire is avoided. Since the inner diameter of the guide hole guiding and supporting the core wire can be approached sufficiently to the outer diameter of the core wire, the core wire can be arranged without any variation over a long distance, precisely at a given position.

Title: Tritium measuring apparatus
Inventor: MICHIGUCHI YOSHIHIRO
IPC: G01T1/167
Filed: 1984-02-22
Abstract: PURPOSE:To enable the detection of tritium to the extent of about 1PCi/cm<3> by use of a detector employing a hydrogen adsorbing metal for a part of an electrode. CONSTITUTION:A hydrogen gas alone is introduced to a radiation detector 5 employing a hydrogen adsorbing metal through a solidifier 1, a hydrolysis unit 3, an oxygen remover 3' and a changeover valve 4. The detector 5 is set at a certain temperature with a temperature controller 6 and the amount of hydrogen determined by the temperature is occluded into a hydrogen adsorbing metal. When the hydrogen in the detector 5 reaches a balanced pressure determined by the set temperature and the type of metal, an ionizing gas fills the detector 5 from an ionizing gas feeder 7. Then, the ionizing gas is ionized by beta ray emitted from tritium in the detector 5. The output of the detector 5 provides one pulse at one decay of tritium and the resulting signal is counted 10 through an amplifier 9. Then, data of the amount of air provided for the measurement from a flowmeter 2 and the number of pulses due to the decay of tritium from a counter 10 are obtained with a controller/arithmetic unit 11 to determine the amount of tritium existing in the air measured.

Title: Device for removing molded product
Inventor: SHINTAKU SEITA
IPC: B29C45/42
Filed: 1987-02-16
Abstract: PURPOSE:To simplify structure of a removing device of a molded product by shortening a period of time required for taking out the molded product, by possessing a shifting mechanism of a holding mechanism, which shifts linearly the holding mechanism of the molded product between a position holding the molded product and a standby position outside of a mold. CONSTITUTION:When molten resin is injected within a stationary mold 16 and movable mold 18, and molding is completed, a movable platen 12 begins shifting from a stationary platen 10, and mold break is begun. Under a state where shifting of the movable platen 12 has completed, a holding mechanism 30 for a molded product at the tip of a taking-out arm 28 arrives up to a position for holding the molded product of a movable mold 18 under a state of mold break. The molded product which is adhered to the movable mold 18 is held by the holding mechanism 30 of the molded product. When the movable platen 12 begins a forward movement toward the stationary platen for the next molding, the taking-out arm 28 begins a backward movement. The holding mechanism 30 or the molded product moves backward down to the standby position by the time when the movable mold 18 becomes the state of the mold break where the movable mold 18 has come into contact with the stationary mold 16, and the removal of the molded product is completed. Since the holding mechanism 30 for the molded product moves directly in the shortest distance, time required for removing the product becomes short.

Filed: 1978-03-18
Abstract: PURPOSE: To eliminate the necessity of the enormous amount of hydrogen, to improve the properties and yield of a caking agent, and to reduce the cost, by using a mixed solvent of methanol for treating coal.  
     CONSTITUTION: The aromatic solvents Y 1  and Y 2 , 3W20 wt.% of methanol M, and coal S are ground by the mill 1 and mixed in the agitating tank 2 to form a slurry, which is then sent to the reactor 6 via the heating furnace 5 by the compression pump 3 under pressure. The methanol is readily decomposed into CO and H 2  to promote the extraction of the organic substances of the coal into the solvent and to prevent the polymerization and coking of the extract. The reaction product is passed through the reducing valve 7, low-pressure separator 8, and separated into a gas and a solid and liquid. The residue Z is removed from the solid and liquid by the solid-liquid separator 9, and the liquid is subjected to equilibrium distillation by the distillation column 10 to give the caking agent N and the mixture K of gas, light oil, and water from the top, and the middle oil T having a boiling point of 250W350°C from the intermediate point of the column 10.
