Title: Casting-crack-preventing mold
Inventor: SAITOU SHIGEKI
IPC: B22C9/02
Filed: 1978-12-22
Abstract: PURPOSE: To ease the mold resistance at the solidification shrinkage of casting and prevent the cracks produced in the casting by inserting the one comprising mixing the specific material in organic-base self-hardening molding sand and making the mixture porous into the back side of the layer formed by organic-base self-hardening molding sand.  
     CONSTITUTION: The one comprising heating the organic-base self-hardening molding sand mixed with material such as foamed polystyrene beads which reduce or lose their volume by the heat of molten metal to about 200W300°C is inserted into the back side of organic-base self-hardening molding sand 1 composed of thickness about 30W50mm of the layer and is molded in a flask 5. The casting 4 cast by disposing backing sand 3 to the mold made in this way has less mold resistance at the solidification shrinkage of casting and has extremely less cracks in the sudden thickness changing parts as compared to conventional ones. The amount of addition of expandable styrene beads may be about 1/2 the volume of the organic molding sand.

Inventor: WATARI KENJI
IPC: B01D63/02
Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To enable potting with high productivity by injecting a first potting resin in a container when at least one end of the separation membrane charged in the container is fixed by a resin and subsequently injecting a second potting resin therein to form a potting part to solidify the same. SOLUTION: As a potting resin constituting a separation membrane module used in the concn. of a liquid or the like, a thermosetting resin is mainly used and becomes a high hardness resin after curing in many cases. In the potting of a hollow-fiber yarn membrane by this thermosetting adhesive resin, a first potting resin is injected in a container and a second potting resin is next injected therein to form a potting part which is, in turn, solidified. If the second potting resin 2 is injected below the first potting resin, the surface of the separation membrane is coated with the first potting resin and subsequently potted by the second potting resin becoming a main component.

Abstract: PURPOSE:To make the boundary between an SiO2 layer and an Si layer flat by a method wherein oxygen ions are implanted into an Si substrate with a low energy from a slant direction and then implanted with a high energy vertically and, after that, oxygen is made to react with Si by annealing. CONSTITUTION:In order to form a buried silicon dioxide layer by implanting oxygen into an Si substrate 1, oxygen ions are implanted into the Si substrate 1 having Miller indices (100) with a low energy (approximately 70keV) from a slant direction so as to have an incident angle about 7 deg. as a first process while the temperature of the Si substrate is kept at about 650 deg.C. (In the figures, marks X denote oxygen atoms in Si.) Then oxygen ions are implanted into the Si substrate 1 with a relatively high energy (approximately 90keV) vertically so as to have an incident angle of 0 deg. as a second process. After that, the substrate is subjected to a thermal treatment (annealing) in an argon atmosphere containing about 0.5% of oxygen at about 132 deg.C for about 6 hours as a third process to form the buried SiO2 layer 2 and an SOI layer 3 having flat boundaries 4 and 5.

Abstract: PROBLEM TO BE SOLVED: To reduce an energy amount to be used for an operation of a heating boiler or to dry a grain only by a solar energy by effectively utilizing the solar energy. SOLUTION: Panels 4 each having a plurality of air intake holes 4a are provided at an outside of a building wall surface. A space 5 extended in a vertical direction is formed between the wall surface and the panels 4.

The warm air takes heat from the holes 4a in the case of passing the holes 4a, and hence the warm air further takes heat from rear surfaces of the panels to rise in the space. Thus, the warm air is introduced into a grain drying chamber as a drying warm air.
