Title: Base isolation structure for building
Inventor: SHIMATANI KAZUHIKO
IPC: E04H9/02
Filed: 1998-07-30
Abstract: PROBLEM TO BE SOLVED: To enable base isolation of the whole building, by supporting a tower against a building body by an elastic body, and constituting a spring-mass system dynamic damper using the tower as a mass and the elastic body as a spring. SOLUTION: A mechine chamber 2 for an elevator is installed on the roof floor of a mid-to-high-rise building 1 and supported by a base isolation device 3 installed under the chamber. The base isolation device 3 supporting the machine chamber 2 for the elevator is formed of a laminated rubber integrally superimposed with thin iron plates and the rubber sheets. The base isolation device 3 vibrates so that the natural frequency of the machine chamber 2 for the elevator becomes nearly equal to the frequency of a forcible external force resulting from an earthquake or the like to absorb the energy of the whole building 1. In this way, a base isolation device is installed only in an existing tower without newly installing an additional vibrating body such as a pendulum or the like. Accordingly, since base isolation of the whole building can be realized, the cost can be reduced.

Filed: 1996-07-16
Abstract: PROBLEM TO BE SOLVED: To obtain a measuring apparatus by which the mass of an object whose position of the center of gravity is not clear can be measured in a very small gravity environment and a weightless environment. SOLUTION: A dynamic vibration absorber 4 in which a measuring base 11 to which an object 10 to be measured is attached is used as dynamic absorption mass is attached to a vibrating base 3, and the vibrating base 3 is excited by a harmonic external force which is generated by an exciter 5. Then the angular frequency of the harmonic external force agrees with the natural frequency of the dynamic vibration absorber 4, the vibration of the vibrating base 4 is suppressed. The amplitude of the harmonic external force is divided by the product of the vibration amplitude of the measuring base 11 in this state multiplied by the square of the angular frequency of the harmonic external force, the mass of the measuring base 1 is subtracted from the quotient, and the mass of the object 10 to be measured can be found.

Abstract: PURPOSE:To make an energizing test for large current without providing a capacitor, etc., by arranging a test cable and dummy cable so that their inductances are cancel each other and supplying thereto approximately equal currents having inverse directions each other. CONSTITUTION:A specified current is supplied to the primary side of a current transformer 4 from a power source 7 through a slidac 6, and the energizing current set beforehand is induced to the test cable 1. At the inside of this test cable 1, the dummy cable 10 which is connected in a loop state with the use of a lead wire 13 for energizing, is arranged. The test cable 1 is mounted on the secondary side of this current transformer 4, and also by means of inverting its polarity, the lead wire 13 for energizing is mounted. As a result, in the case the current is made to flow to the cable 1 in the direction of the arrow 11 at a certain moment, the current is made to flow to the cable 10 in the direction of the arrow 12, i.e. opposite direction to the cable 1. Consequently, magnetic fields to be formed are cancelled each other when the energizing current values for both are equal.

Abstract: PURPOSE: To provide a method of removing surface particulate matter from an article at a low cost by immersing an article heated to a sufficiently high temperature in a bath of liquid cryogen and removing the article from the bath of liquid cryogen after the both have reached thermal equibrium. CONSTITUTION: The articles 12 are immersed in a bath of liquid cryogen 14 which is chemically nonreactive with the articles 12 to be cleaned. Prior to immersion, it is necessary for the articles 12 to have a sufficiently high temperature above that of the liquid cryogen 14 and during immersion it is also necessary to immerse the articles at a sufficient rate such that the liquid cryogen 14 undergoes film boiling at the surfaces of the articles 12 to afterthat conduct nucleate boiling. The articles 12 are left immersed so that the nucleate boiling of liquid cryogen 14 occurs at the surfaces of the articles. During the nucleate boiling, the surface particulate matter 27 is carried from the articles 12 and settled into the bath of liquid cryogen 14. After the articles 12 have reached thermal equilibrium with the liquid cryogen 14, the articles 12 are removed from the bath.

Abstract: PROBLEM TO BE SOLVED: To move an image inputting part at a narrower pitch than a width equivalent to one side of one picture element for constituting a frame memory and to improve measurement accuracy by providing an image inputting part, a traveling means, a frame memory, and a control part. SOLUTION: A camera for inputting image and a measurement target are relatively moved a width which is equal to or less than 1/2 of a width equivalent to one side of one picture element so that a viewpoint by the camera for inputting image moves in the direction of an arrow 19. A true edge part T1 of a pattern 11 to be measured does not exceed a boundary position T3 of a picture element 16-2 and a picture element 16-3. That is, the true edge part T1 of the pattern 11 to be measured can be predicted to exist within a range of a range N which is limited by a disector M2 of the picture element 16-2 and the boundary position T3. At this time, since a relationship (a width equivalent to one side of one picture element) = |L| = 2|N| can be established, a measurement accuracy can be improved doubly.

Inventor: MIYAKI YOSHIMITSU
IPC: C22C1/02
Filed: 1983-11-18
Abstract: PURPOSE:To improve toughness, fatigue strength, workability and resistance to stress corrosion cracking by irradiating the ray flux having a high energy density to a large-sized casting ingot consisting of a metal or alloy to effect continuously local remelting and solidification thereby forming finer structure and increasing the solid solubility limit of the additive elements. CONSTITUTION:A large-sized casting ingot of a metal or alloy is generally low in cooling rate and therefore the crystal grain size is large and in the case of an alloy, an intermetallic compd. is crystallized by which the workability in rolling, extruding, casting, etc. is deteriorated and various physical characteristics are deteriorated. The ray flux having a high energy density such as electron beam, plasma arc or the like is irradiated from the surface to the large-sized casting ingot in this case to effect local remelting and succeeding quick cooling. The crystal grain size of the casting ingot is made fine and in the case of the alloy, the solid solubility limit of the alloy elements is increased, by which the hot and cold workability is improved and the toughness, fatigue strength, corrosion resistance, etc. of the worked product are improved.
