Abstract: PURPOSE:To reduce the number of signals connected to an operation verifying circuit. CONSTITUTION:The operating results of a function circuit 9 are output as operating result outputs 8, and the operating results are verified whether they are correct or not by an operation verifying circuit 5. AND circuits 1 and 3, and NOR circuits 2 and 4 which are logical circuits are circuits unable to be verified sufficiently whether the operation is correct or not by only verifying the operation result outputs 8, and these logical circuits have a low frequency to make the output '1'. As a result, the outputs of these four logical circuits are added to the input end of an OR circuit 6, the logical sum is picked up from the signal line being the output end of the OR circuit 6, and it is verified by the operation verifying circuit 5. Even in such a way, a sufficient verifying is secured.

Title: Cooling mechanism of resin granulating machine
Inventor: AMANO TERUYOSHI
IPC: B29B17/00
Filed: 1984-05-01
Abstract: PURPOSE:To obtain a product free from dispersion in quality by connecting the end of a heat pipe laid around an extrusion port on a suitable cooling device. CONSTITUTION:Resin scrap in the conveyor chamber 1c which is extruded in a semigelled form is cooled and begins to harden at the extrusion port 6 and nearly completes hardening in a granular form. However, since the heat pipe 15 is laid in the wall along the circumference of the extrusion port and both ends of the heat pipe abut on the water tank 16, the whole circumference of the extrusion port is kept in a uniform temperature and the melted and semigelled scrap material can be cooled quickly and uniformly. The cooling temperature can be controlled easily on the cooling mechanism side. Therefore, the scrap material cut in a granular form can be recovered without being loosened and as it is and defects which are stuck to each other are hardly found.
