Title: Method for reaction injection molding
Inventor: YAMATO MOTOTOSHI
IPC: B29C39/00
Filed: 1986-10-31
Abstract: PURPOSE:To obtain a molding with favorable surface condition having no sink mark by a method wherein a sheet is held on one surface in a mold at reaction injection molding. CONSTITUTION:A sheet is held on one surface in a mold at reaction injection molding. For example, a sheet is fixed softly on one surface in the mold 1 by applying double-sided adhesive tapes at several positions. Or one end of the sheet 2 is pinched between a top and a bottom forces 1 and 1. Or a force to which the sheet 2 is set is placed down. A sheet which neither melts by molding material nor deforms due to the heat generating during polymerization and hardening reaction is favorable. Especially, a Teflon sheet gives favorable effects regardless of the kind of molding material. When molding material is poured in a high-temperature mold, the material quickly polymerizes and hardens itself in the solid form and shrinks. When the sheet is held on one surface of the mold, the sheet tightly joins onto the surface of a molding and slides together with the cure shrinkage of the material, resulting in preventing sink mark followed by the shrinkage from developing.

Abstract: PURPOSE:To electrify the surface of a photosensitive drum to a uniform electrifying potential by means of a brush and to eliminate the need of an electrifying charger by setting a voltage impressed on the brush to a potential for electrifying the surface of the photosensitive drum. CONSTITUTION:The voltage impressed on the brush 2 from a high voltage power source 3 is selected/set to a value that the surface potential of the photosensitive drum 1 disposed opposite to the brush 2 can be set to the electrifying potential. On the other hand, residual toner after a transfer process, is uniformly dispersed on the surface of the photosensitive drum 1 by a high voltage impressed on the brush 2, and carried to the position of a developing unit 6, in this state. Therefore, the residual toner dispersed by the brush 2 and stuck to an unexposed part is recovered to the side of the developing unit 6, by the potential difference of a developing bias on the developing unit 6 and the surface potential on the unexposed part of the photosensitive drum 1. Thus, the electrifying action of the photosensitive drum 1 is carried without providing the electrifying charger.

Abstract: PURPOSE:To sense positive ions, negative ions, and neutral particles simultaneously by furnishing respective sensors on the tracks through utilization of the facts that neg. ions deflect to the left and the neutral particles go straight while the positive ions incident are deflecting to the right. CONSTITUTION:All ion beams 2 emitted from an ion source 1 are dispersed by the mag. field 3 according to the mass vs. electric charge ratio and deflected with the radius of curvature depending upon the ion accelerating voltage and the intensity of mag. field and only specific ions P5 will pass the electric field 4. This ion beam P5 is converged by combination of the mag. field 3 and electric field 4 and passes a slit A6. In a reaction chamber 7, this ion beam P5 impinge on He gas 8 for impinging activation, and dissociated ions F10 pass another slit B9. In a circular mag. field 11, for ex., a pos. jon F+12 and a neg. ion F-13 are deflected oppositely while a neutral particle N14 goes straight. Sensors 20-22 are thus located at the convergence point meeting the ion-optical convergence conditions for the ions, and in the straight running position for the neutral particles. This enables simultaneous sensing of pos. ions, neg. ions, and neutral particles.
