Inventor: UEHARA TADAYOSHI
IPC: B29C45/56
Filed: 1986-07-18
Abstract: PURPOSE:To enable the title method to manufacture a high-precision cylindrical material, by a method wherein a cavity side is swollen out into a molding cavity by raising pressure of a hydraulic fluid of a pressurizing device after filing of synthetic resin. CONSTITUTION:The inside of a molding cavity 11 formed by descending a movable side template 20 is kept at a predetermined temperature and molten synthetic resin is injected within the cavity 11 by feeding the molten synthetic resin to a sprue 62 with pressure. In this instance, when the movable side template 20 is descended until the same abuts against a cavity block 30, a piston 82 of a pressurizing device 80 is pressed by the movable side template 20 and a cavity side 52 is swollen out into the molding cavity 11 by hydraulic pressure of hydraulic oil 85 with which the inside of a pressurizing chamber 84 is filled. Therefore, the molten resin in the molding cavity 11 is compressed in a diametral direction by the cavity side 52, stretched in an axial direction, and filled out to every nook and corner of the cavity 11 such as a male screw part 53 and air gaps are removed in detail. Therefore, the molded product can obtain sufficient accuracy.

Filed: 1985-08-01
Abstract: PURPOSE:To secure necessary resolution eliminating the redundancy, by processing the demodulated reception signal with a plurality of filters with the pass band set according to the diagonal distance to a irradiation field. CONSTITUTION:The equiphase component I of the reflected reception signal which is demodulated after synchronously detected with a synchronous detection circuit 7 is processed with an LPF8 with the pass band corresponding to the signal received from a near irradiation field and a quantization circuit 13 while being processed with an LPF8 with the phase band corresponding to the signal received from a far irradiation field and a quantization circuit 14. The same is performed with the component Q orthogonal to the component I of the reflected reception signal. This eliminates the redundancy of the frequency band more than required to keep necessary distance resolution for the far irradiation reception signal as in the processing of signals received from far and near irradiation fields with one LPF thereby simplifying the processing of the received signal with secured necessary resolution while getting rid of the redundancy.

Abstract: PROBLEM TO BE SOLVED: To evaluate in a short time a layer structure of a resin coat layer of a metallic plate coated with a resin including polyethylene terephthalate by irradiating a section of the resin coat layer with a laser light and measuring a Raman spectrum. SOLUTION: In order to evaluate a resin coat layer of a metallic plate coated with a resin including polyethylene terephthalate(PET), a section of the resin coat layer is irradiated with a laser light and a Raman spectrum is measured. In other words, a half width of a peak resulting from a C=0 stretching vibration near 1730 cm-1 of a Raman shift among the Raman spectrum obtained by irradiating the section of the resin coat layer with the laser light is obtained. A density of the PET resin and the peak half width have a good correlation and are proportional to each other. A linearly polarized or unpolarized laser light is used as the irradiating laser light. According to the method, the resin coat layer can be highly accurately evaluated, enabling quality control for stable production of the resin coated metallic plate.
