  • Patent number: 5539004
    Abstract: A process and an apparatus for recycling resin scrap including a thermosetting resin paint film and a thermoplastic resin substrate as its major components, wherein the resin scrap is supplied into a passage of a cylinder, melted, and delivered by delivering means from an upstream side to a downstream side of the passage of the cylinder, and hydrolyzed by a hydrolyzing agent while forming a highly packed region with a resistor. The resistor restricts the resin scrap to flow from the upstream side to the downstream side in a short period of time, and forms the highly packed region where a contact efficiency is enhanced between the resin scrap and the hydrolyzing agent.

  • Patent number: 5458829
    Abstract: Waste parts made of synthetic resin and having a hydrolyzable coating thereon are crushed into chips. The chips are supplied quantitatively to a hydrolyzer apparatus where they are continuously transported through the hydrolyzer with a screw while in contact with steam so as to hydrolyze the coating. The chips with the hydrolyzed coating are dried in a drying furnace and the dried chips are transported to a kneader wherein the hydrolyzed coating is kneaded into chips. The kneaded chips are cooled and then pelletized into pellets in a pelletizing apparatus.

  • Patent number: 4960548
    Abstract: A method of manufacturing a molded wooden product includes the steps of: preparing a ligneous molding material by adding a binder essentially consisting of a synthetic resin and the like to wood fibers; adjusting the weight of the molding material in a fibrous state or in a state of being aggregated into a predetermined configuration; directly supplying the molding material to a shaping mold; shaping the outer periphery of the molding material by moving the shaping mold toward the center in conformity with the final external shape of a molded product; and hot compression molding the molding material, thereby obtaining a molded wooden product of a predetermined configuration.

  • Patent number: 4660053
    Abstract: In a thermal transfer recording method for use in a recording apparatus using a roll of recording paper of an ordinary paper material wound about a core and a strip of ink ribbon would about an ink ribbon feeding roll, recording is effected by means of a thermal head while both the recording paper and the ink ribbon are transported forwardly in the superimposed state. During transportation of the recording paper and the ink ribbon after the recording, they are parted away one from the other and only the recording paper is transported to an automatic cutter by means of which a part of the recording paper on which recording has been effected is cut off. After completion of cutting operation an unused parts of the recording paper and the ink ribbon are transported backwardly to the position where the leading end of the thus returned recording paper is located in the proximity of the thermal head.

  • Patent number: 4470288
    Abstract: Manufacturing method for a tubular shell of a constant velocity universal-joint for flexibly coupling two rotary shafts, to one of which the shell is fixed at a flange thereof. The method comprises a groove and preliminary flange forming process and a flange forming process. In the former process a hollow cylindrical blank is applied pressing in a radial direction for forming plural grooves therein and forming at the same time a preliminary flange at one end of the cylindrical blank by expanding it into a funnel shape, and in the latter process the preliminary flange formed on a semi-finished article in the former process is formed into a completed flange by a flange forming die, while holding the semi-finished article in a restrained status under pressure from either side, external and internal, by means of restraining dies. An apparatus suitable for performing the method is also disclosed.

  • Patent number: 4453395
    Abstract: A shell for a universal joint for flexibly coupling two rotary shafts. The shell is constructed using a manufacturing technique to produce a shell of light weight and excellent strength. The shell generally has a hollow cylindrical configuration and is secured at one end to a rotary shaft and formed to have a plurality of grooves extending parallel to its cylindrical axis. A second rotary shaft includes portions which engage the plurality of grooves for transmitting movement from one shaft to the other through the shell. The shell may be formed using a tubular work piece or a planar work piece, and may be provided in substantially complete form by use of a machine press prior to subjecting the material to an ironing process to make the grooves of accurate shape and dimension. The process is performed such that no machining is required to form the grooves and produce the shell.
