Title: Method and apparatus for molding mold
Inventor: ISHIZAKA RYUZABURO
IPC: B22C15/02
Filed: 1990-10-16
Abstract: PURPOSE:To obtain a precise mold without any deformation by fitting low friction member to inner wall face, shifting into a flask after packing molding sand in an auxiliary flask having size of interval between walls smaller than size of interval between walls of the flask and fixing the molding sand to the flask with an upper peripheral segment. CONSTITUTION:On a lower pressurizing segment 24', a molding board 27 and a side mold 22 are mounted. The upper segment 24 which can receive/pressurize the molding sand 21 independently and arbitrarily according to the shape of the side mold 22 is arranged. Then, the low friction member 11 is fitted on the inner wall face of auxiliary flask 20. The size of interval between the walls of auxiliary flask 20 is a little smaller than the size of interval between the walls of flask, and after packing the molding sand 21 in the auxiliary flask 20, this is shifted in the flask 23 and the molding sand 21 is fixed to the flask 23 with the upper peripheral segment 24. By this method, internal stress to be cause of deformation of the mold can be relieved.

Abstract: PURPOSE:To minimize the built-in area of aggregate components with microelectronic components electrically connected in vertical layout by electrically connecting a solder bump in the bottom of a microelectronic component to a metal conductor with a solder connection jig interposed in a closer-to-tip part of a tubular reinforcement member so as to be orthogonal to the major axis of the reinforcement member. CONSTITUTION:Microelectronic components 5 are so laid out as to be orthogonal to the major axis of a reinforcement pipe 3. With a lower mount fixing ring 19 kept still, an upper microcomponent ring 21 is pressed down. A solder bump 7 in the bottom of a microelectronic component 5 contacts a solder ball 13 half exposed from the top of the connection jig 9. At this time, the solder ball 13 also contacts the top of a metal conductor in a throughhole of the connection jig 9. solder is fused by selectively heating this zone from outside the reinforcement pipe 3, and solder solidifies on later cooling, resulting in an electrical connection of a microelectronic component 5 and a metal conductor 17.

Abstract: PURPOSE:To suppress light returning to a light emitting source, by providing plural various element on a substrate and means which give light transmitting characteristics unreversible in the transmitting direction between the elements on the substrate and to the light emitting surfaces of elements having laser light emitting functions among the elements of other substrates. CONSTITUTION:Parallel light transmitting signals are converted into parallel electrical signals by means of a photodetector element array 3 and the parallel electric signals are subjected to processes, such as intersignal operation, switching of signal route, etc., at a electronic circuit chip 4. The processed electric signals are inputted in a semiconductor laser array 5 and, after they are converted into optical signals again, sent to an output optical fiber 8. In order to stably operate the individual oscillation of the semiconductor laser array 5 without noises, it is necessary to suppress reflecting lights produced at the connecting point of an optical waveguide 9 which leads the light emitted by the laser array 5 to the optical fiber 8 and the optical fiber 8 and the returning light by reflection from the other end of the optical fiber 8. Since an optical isolator 6 provided at the light outgoing end face of the laser array 5 rotates the polarized light of the above-mentioned reflected returning light by 90 deg., nonoise is induced to the laser array 5.

Title: Cushioning material
Inventor: HORIUCHI KUNIHIRO
IPC: B65D81/107
Filed: 1992-09-24
Abstract: PURPOSE:To make the impact absorbing force larger, and make it recyclable by making a single-faced corrugated fiberboard into a pillar shape by winding by several layers. CONSTITUTION:A single-faced corrugated fiberboard 2 is made into a pillar shape by winding by several layers, and respective interlayer parts are not bonded or bonded only by appropriate intervals. Therefore, when an impact is received, the center core 1 can be relieved, and also the relieving direction, i.e., crushing direction does not become one direction, and a buckling phenomenon of the center core 1 does not take place, and a sufficient cushioning effect can be presented. Also, when the outer the center core 1 is formed on the outer peripheral side of the single-faced corrugated fiberboard 2, the wider the relieving space becomes, and the cushioning effect can be increased. Also, the winding final end of the one-face corrugated fiberboard 2 is fixed while remaining a bonding edge piece at the tip, for a packaging material. In addition, on the outermost side of the wound cushioning material, a cylindrical frame made of a paper, fabric, or elastic metal plate is wound. By doing this, the center core 1 only deforms and is restored without being buckled, and therefore, repeated absorbings of an impact are possible.
