Filed: 1995-02-28
Abstract: PURPOSE: To prevent a building from being damaged when a huge earthquake occurs, by a method wherein part of a foundation bed and foundation are so formed as to be easy to disintegrate as compared with the other part thereof and are disintegrated by its vibrational energy only at the occurrence of the huge earthquake, and they are apparently separated from the building, and hence the vibration of them is not directly propagated to the building. CONSTITUTION: Ground 1 is leveled and strengthened in conformity with predetermined regulations, according to the shape and scale of a building 3. A foundation 2 is formed on the place whereat broken stones 4 are laid and leveling concrete 5 is placed. The building 3 is constructed in conformity with predetermined regulations and is made earthquakeproof. In addition, part of the foundation 2 is formed of a disintegrable material layer 21 which is made a little weaker than the other part thereof, and is so formed as to be disintegrated only by its vibrational energy at the occurrence of a huge earthquake. In this way, the connection between the foundation 2 and the building 3 is apparently released.  Granular and lump material desintegrated lies between the ground 1, the foundation 2 and the building 3, and prevents the vibration of the foundation 2 from being directly propagated to the building 3, and hence the quake of the building 3 is made smaller and the building 3 is saved from its damage.

Title: Heat exchanger
Inventor: IWANAGA SHIGERU
IPC: F28D7/00
Filed: 1982-04-22
Abstract: PURPOSE:To obtain the heat exchanger which has a small heat conduction resistance and is compact in size and which is manufactured at low cost, by a method wherein a flow regulating member for a heat medium is arranged within an inner cylinder having a number of fins on the inner surface thereof leaving a clearance from the latter so that the clearance serves as a primary side fluid passage and a heat conductive member having a secondary side fluid conduit embedded therein is bonded tightly to the outer circumference of the inner cylinder. CONSTITUTION:The heat medium which is a high temperature gas from a primary side fluid inlet port 5 enters a primary side fluid passage 10 divided into a number of sections, through an inlet chamber 11. In this case, the heat medium radiates heat to the water in a pipe 13 through the inner surface of the inner cylinder, fins 2 and a heat conductive member 16, condenses to become a low temperature liquid which collects in an outlet chamber 12 and flows out from a primary side fluid outlet port 6. At the same time, the water enters the pipe 13 from a secondary side fluid inlet port 14, flows upward along the outer periphery of the inner cylinder in a helical fashion so as to be heated to an elevated temperature by the high temperature heat medium and flows out from a secondary side fluid flow-out port 15 provided at the upper part of the heat exchanger. Thus, as the heat medium flows vertically from the upper part down to the lower part of the heat exchanger, the condensed and liquefied heat medium falls down smoothly to the lower part of the heat exchanger. Accordingly, the liquid film generating on the heat transfer wall of the heat exchanger at the time of condensation of the heat medium become thin so that the increase of thermal resistance due to an increase in the thickness of the liquid film is prevented and the heat transfer efficiency of the heat exchanger is improved.

Title: Manufacture of semiconductor ic device
Inventor: AKASAKA YOUICHI
IPC: H01L21/82
Filed: 1984-04-04
Abstract: PURPOSE:To obtain the titled device regardless of the thickness of protection film and without the adverse effect of the dispersion of a fuse medium by a method wherein the fuse medium is covered with a protection film in the part other than the section to be fused, and is irradiated with laser beams. CONSTITUTION:An SiO2 film 2, a poly Si 3 (fuse medium), and a PSG4 are superposed on the inactive region of an Si substrate 1. The PSG4 is opened 7 and the protection film 6 is deposited, which is then opened 8 smaller than the hole 7, thus exposing the poly Si 3. Next, the poly Si 3 is fused 9 by irradiation with laser beams I through the hole 8. This construction enables secure fusion with good reproducibility without being influenced by the thickness of the protection film 6, because of direct irradiation of the poly Si 3. Further, the protection film 6 allows the deposition of the substance dispersing by fusion entirely on the film 6, resulting in no harmfulness.

Title: Foam molding mold
Inventor: KITANO MINORU
IPC: B29C33/26
Filed: 1991-04-01
Abstract: PURPOSE:To eliminate the development of non-conforming article due to the development of burr following by the spouting of gas during foam molding or to the puncture of urethane foam and, at the same time, increase the speed of processing and, in addition, prevent non-conforming article from developing due to residual gas by releasing the gas at the proper time. CONSTITUTION:An upper mold 5 is vertically and slidingly opened and closed along guide groove 21, with which the upper mold 5 is horizontally supported. The opening and closing actions can be quickly and smoothly carried out due to the direction of the inclination of the lower end part 21a of the guide groove. As a result, catalyst and raw material having high reaction speed can be selectively adopted and mold clamping can be executed at the front and rear of the mold, thus preventing the spouting of gas at the rear of the mold, which may occur in the conventional mold having a hinge pivoting system. Further, since clamping claws 53 can take two stage clamping positions after mold closing, gas can be released at the proper time.
