摘要： PURPOSE:To prevent the generation of gel in a mixing part by providing both a specified discharge means of a mixed raw material and a feed means of washing fluid in a mixing head wherein plural raw materials are introduced into a clearance between the faces having relative velocity difference and mixed by shearing force. CONSTITUTION:When raw materials A, B are discharged through the discharge ports 8, 9 for the raw materials, the discharge pressure overcomes stress of an elastic body 13, a clearance is formed between the faces 5, 6, and the raw materials are fed to the clearance. According as a rotator 14 is rotated in high speed the raw materials are received with shearing force by the relative velocity difference caused between a concave type cone face 5 and a convex type cone face 6, mixed and injected through an injection port 7. Then when the injection is finished by stopping the feed of the raw materials, the faces 5, 6 are closely stuck by energizing force 15 of the elastic body 13 and the residual mixed liquid is discharged. When washing liquid (gas) is fed under pressure nearly overcoming the energizing force 15 of the elastic body 13, the faces 5, 6 are pushed and opened and the faces 5, 6 are washed by rotating the rotator 14 in high speed while holding the resulting minute clearance.

摘要： PURPOSE:To make the preparation of cylindrical frame for telescoping lenses easier, to obtain the accuracy easier and to reduce the labor cost, by pouring and solidifying a resin in the space between a fixed cylinder and a metal mold main body for injection-molding to form a resin layer and cavities for holding sphere balls on the surface of the fixed cylinder. CONSTITUTION:A fixed cylinder 17 of the cylindrical frame for telescoping lenses is inserted and positioned in a metal mold main body for injection-molding 8. Pins 9 for forming cavities are then inserted into a positioning block 15. Steel sphere balls 11 pressed into the top parts of the pins 9 for forming cavities are positioned in such positions that the cavities can be formed to hold sphere balls 33 in the position fitted to multi-screw grooves 31 of the rotational cylinder 30 of the cylindrical frame for telescoping lenses. An epoxy resin is poured from a pouring hole 22 and cured at room temp. or by heating. When assembling after curing, a sphere ball 33 is inserted into each cavity of the fixed cylinder 17 and fitted to the screw grooves 31 of the rotational cylinder 30. As the accuracy of the positioning of the sphere balls is easily obtained by this means, the accuracy of the cylindrical frame can be therefore easily obtained.

摘要： PURPOSE:To contrive to shorten a molding cycle, by heating the outer surface of a rubber mold by means of a heating plate, by forming a metal bar and/or a metal block contacted with the heating plate in the part of large thickness and by sending hot air between a cavity and a core. CONSTITUTION:A rubber mold consists of a core 2 and a cavity 3 and a reductive hole 7 is formed in the part of large thickness where an aluminum block has been located in advance. Hot plates 8, 10 are formed above and below the mold and an aluminum block contacted with the hot plate 8 is set. The hot plates are heated by means of cylindrical heaters 11, 12 and the temp. is kept at 160 deg.C by means of sensors 14, 15. Hot air controlled at 160 deg.C by means of an industrial air heater is blown from an inlet 5 and exhausted from an outlet 6. It is made possible by these means to accelerate the heating speed of the rubber mold by more than four times and to stabilize the reaction temp. which is most important.

摘要： PURPOSE:To obtain accuracy of a specular barrel easily and to omit a process requiring manhour, by a method wherein a plurality of pieces of spheres is made to abut against a cylindrical surface of a forerunner of the specular barrel by a supporting member at predetermined positions and a resin layer is formed by casting and curing resin into a void between the forerunner of the specular barrel and the cylindrical surface. CONSTITUTION:A stationary cylinder 20 of a specular barrel for drawing-out of a lens is inserted into a main body 8 of a casting mold for positioning. The a positioning block 18 of a fixing pin is fitted to a predetermined position and steel balls 9-11 are inserted into the block 18 by fitting them to the tip of magnetized fixing pins 12-14. Then a holding plate 19 of the pin is fitted by inserting press springs 15-17. Hereupon, the steel balls 9-11 are positioned at positions of fitting in a multiple flighted thread groove of a rotating cylinder of a specular barrel for drawing-out of the lens. To fix the steel balls 9-11 on a cylindrical surface, epoxy series resin is cast through a resin casting port 25 and the stationary cylinder 20 is unloaded by removing a jig after completion of cure. Accuracy of the specular barrel is obtained easily by keeping the positioning block of the pin processed by improving accuracy of the same.

摘要： PURPOSE:To enhance the quality of ferrite products such as magnetic head by provisionally fixing a ferrite work on the base table through the use of an ultraviolet hardening resin, machining is and removing with the resin swollen with an organic solvent. CONSTITUTION:A ferrite work given an approximate contour previously 1 is placed on a ceramic base table 2 and located fast by a locating jig 3, and is coated with an ultraviolet hardening resin 5 using a dispenser 4. Then ultraviolet radiations are applied while he ferrite work 1 is held by the jig 3 provisionally until the ultraviolet hardening resin 5 hardens. After the work 1 is machined, an organic solvent 7 is dripped over this processed work 1 by the use of a dispenser 8 to bring about swelling of the resin 5, and a mechanical external force is applied with a defoliating jig 9. Then the work 1 is removed from the base table 2. In the product thus obtained, contaminations due to resin residues on the ferrite surface are reduced to assure an enhanced quality.
