Abstract: The present invention provides for a process for preparing hollow polymer latexes. A first charge of a organic phase is introduced to an aqueous phase. The first charge of the organic phase comprises monomer, which is virtually insoluble in the aqueous phase, and an inert-nonpolymerizable hydrocarbon. The polymer formed from polymerizing the monomer is virtually insoluble in the hydrocarbon, the hydrocarbon is virtually insoluble in the aqueous phase and the monomer is miscible with the hydrocarbon. The monomer is polymerized to produce a low molecular weight polymer which phase separates from the organic phase and concentrates at the surface of the organic phase forming a low molecular weight polymer phase. A second charge of the organic phase is then introduced to the aqueous phase when the low molecular weight polymer reaches a conversion of monomer to polymer of equal to or less than 80 percent, wherein the second charge of the organic phase comprises a crosslinking monomer and wherein the crosslinking monomer is imbibed in the low molecular weight polymer phase. Further polymerization produces a hollow polymer latex particle.

Abstract: PURPOSE:To get a high-efficiency type explosive generator by continuously changing the quantity of charged explosive so that the quantity of charged explosive may be small at start of explosion of an explosive and maximum at the end of explosion when the condensation of a magnetic field is maximum. CONSTITUTION:In the case of a coil-type generator, a spacer 9 is inserted in the center of the generator 1, and an explosive 8 is charged around it. And, the material of the spacer 9 is an inert resin such as acrylic resin, and the shape is conical. Accordingly, the quantity of explosive charged between the spacer 9 and the inwall of an armature 1 is becomes larger continuously from the starting point of explosion where a triggering device 5 exists to the end point of explosion. As a result, the quantity of explosive per unit length in advance direction of explosion becomes larger gradually, and it can enough exhibit the compressive force surpassing the force of resisting the reduction of a gap 2, so the quantity of explosive can be saved as compared with a conventional explosive, and a high-efficiency type explosive generator capable of efficient power generation can be gotten.

Abstract: A positive photosensitive printing plate is prepared wherein the photosensitivity is to near-infrared rays which do not induce a chemical change in a photosensitive component. The photosensitive material has an inclined structure from the viewpoint of dissolution of the irradiated portion in an alkali developer. The dissolution rate is such that it continuously increases from the upper, surface part of the photosensitive material to the lower part of the photosensitive material. This effect may be enhanced by diffusion of a material, preferably a polar compound, such as H2O, from the surface toward the inner lower part of the photosensitive material. Techniques for accomplishing the diffusion include contacting the surface of the photosensitive material with an atmosphere of high humidity or overlaying the photosensitive material with a layer of protective material (paper) containing moisture and heating the resultant composite. The photosensitive material may include a solubility suppressing agent such as a sulfonic acid ester or a compound having a triarylmethane skeleton.

Abstract: A quick connector assembly for coupling a flexible hose or tube to a bore formed in a housing thereby to establish fluid communication between the interiors of the hose and bore, respectively, comprises an elongate tubular male insert having one end adapted to receive and retain the tube about its periphery. The other end of the male insert includes a contoured external surface defining an external locking flange, and a pair of axially-spaced external circumferential grooves for receiving a pair of O-rings which ultimately sealingly engage complementary cylindrical sections of the housing bore upon insertion of the connector assembly thereinto. Prior to its insertion into the housing bore, the connector assembly includes a garter spring which is radially collapsed about the male insert's contoured external surface by an encompassing annular spring guide. Upon inserting the connector assembly into the housing bore, the spring guide first seats itself against the housing and the garter spring is thereafter displaced by the locking flange from its radially-collapsed pre-insertion position within the spring guide down into the housing bore and, ultimately, into a locking groove formed internally of the housing bore. The garter spring thereafter further expands to allow the locking flange to pass therethrough and then radially contracts upon full insertion of the male insert into the housing bore to lock the connector assembly therein.
