Patent JP-S6442184-A (JP)
Title: Manufacture of thermocouple
Inventor: WASHINO AKIRA
IPC: H01L35/34
Filed: 1987-08-08
Abstract: PURPOSE:To obtain a thermocouple which has a high relative density and hence has excellent electrical and mechanical characteristics with a low cost as a whole by a method wherein the raw materials are tempered into fine uniform particles and kneaded with organic materials, injection-molded and sintered by debindering. CONSTITUTION:The material of a P-type thermoelectric element and the material of an N-type thermoelectric element each are tempered into approximately spherical fine and uniform particles with diameters of 2-5mum and kneaded with binder whose volume ratio to the thermoelectric materials is 40% to obtain soft mixtures. Then the kneaded mixtures each are injected into a mold which has at least two apertures from the respective ends and unified at a predetermined position in the mold. The injection molding is gradually heated to eliminate most of the organic materials in the molded unit. The debindered molding is heated at a high temperature and the temperature is maintained until the molded unit is alloyed with uniform components by the diffusion of the respective atoms and sintered. With this constitution, the relative density can be improved to 95%-97% as a whole and, moreover, by the uniform distribution of voids, a thermocouple which has a reduced resistance and can take out an electromotive force without attenuation electrically and which has an extremely high ductility mechanically can be obtained.

Title: Hot runner for injection molding machine
Inventor: OKADA NORIHISA
IPC: B29C45/26
Filed: 1990-07-30
Abstract: PURPOSE:To prevent a rocking end face of a runner main body and a roller from getting worn and improve durability by bringing the rocking end face into contact with the roller by means of a coned disk spring and also bringing a tip into contact with a resin feeding hole by means of a fluid pressure cylinder. CONSTITUTION:When a piston rod 25 is moved forward by means of hydraulic pressure of a hydraulic pressure cylinder 24, a tip 29 is brought into contact with a resin feeding hole 8. When a runner main body 15 is rocked, the piston rod 25 is bent, and the runner main body is rocked smoothly without trouble even if plate-shaped sections 25a and 27 are fixed. Also, as a rocking end face of the runner main body 15 is brought into contact with a rotating roller 18, the rocking end face and the roller 18 are free from getting worn. After that, molten resin injected out of a nozzle 1 passes through a resin path 15b and the tip 29 and is injected from the resin feeding hole 8 into a cavity of mold and solidified to manufacture a molded product. At that time, when the runner main body 15 is thermal expanded, its rocking end face is brought into contact with the roller 18 and its movement to the left in the drawing is restricted, and the runner main body 15 is stretched to the right of the drawing in a manner of compressing a cured disk spring 20, and thermal expansion is absorbed by the corned disk spring 20.

A secondary electron 202 generated from the substrate 12 is guided to a secondary electron detector 14 by means of a reflector 300, and its output signal is transmitted to an image processing unit 104 for detecting a defect and the like on the substrate surface. When scanning the electron beam device is stopped temporarily, electric excitation of the condenser lens 3 is regulated so as to reduce focussing, so that current quantity of the electron beam passing through the objective diaphragm 4 is reduced by about 30-60%.  The electron beam is deflected from an aperture of a blanking diaphragm 7 by mean of the deflector 5 so as to be blanked.

Title: Rolling method for high polymer
Inventor: WATANABE KAZUO
IPC: B29L7/00
Filed: 1988-08-12
Abstract: PURPOSE:To enable a material having a high melting point to be rolled up to the minimized wall thickness stably and efficiently by installing a heat keeping furnace in front and the behind of a rolling machine, and rolling it while the material temperature is being kept constant upon rolling high polymer. CONSTITUTION:Polypropylene 2 is in the region of about 160 deg.C in its melting point, and heated at 140 deg.C immediately lower thereof, and started to roll by a rolling machine 1. As the pass number advances and the time lapses gradually, the thinner the material thickness, the lower the material temperature, and as the critical temperature becomes 100 deg.C or less in this instance, deformation resistance increases, at the same time, edge cracks or the like arise, so that the rolling can not be continued virtually. At this time, in order to prevent lowering of the material temperature, heat keeping furnaces 3, 4 are installed on tables in front and the behind of the rolling machine 1, and, it is required that the material should always be rolled therein. That is, it means that the material 2 is kept at all times in the heat keeping furnaces 3, 4, and thus, the material temperature is held at an approximately constant state.
