Title: Differential heat balance
Inventor: UCHIDA HIROSHI
IPC: G01G19/00
Filed: 1987-07-06
Abstract: PURPOSE:To simplify a component construction, by a method wherein a connecting rod is connected to one end of each of two balances while a sample and a reference sample are mounted at the other end thereof in the same furnace and the inclination of the balances is compensated for with an electromagnetic device. CONSTITUTION:As the weight of a sample 5 varies with a change in the temperature of a furnace 7, an output of a differential transformer 16 due to inclination of a balance 1 is amplified with an amplifier 18 to be applied to a coil 14 and the inclination thereof is compensated for to achieve equilibrium of the balance 1. Change in the weight of the sample 5 is obtained by an output of the amplifier 18. Variation of buoyancy, agglutination of a gas generated and the like attributed to a temperature change in the furnace 7 work on the sample 5 and a reference sample 6 simultaneously in the same direction so that balances 1 and 2 tend to incline in the same direction, but the inclinations thereof cancel each other with a connecting rod 10 to give no effect on the input and output of the amplifier 18. Thus, an output of the amplifier only responds to changes in mass, thereby producing a simple mechanism with the prevention of the generation of errors.

Abstract: PURPOSE:To form the longer-sized tape and to improve the quality thereof by ejecting the Mg or Mg alloy of a specific temp. held in a stainless steel crucible onto the surface of a roll made of an Al alloy, etc. and quickly cooling the same. CONSTITUTION:The molten Mg or Mg alloy held at 700-900 deg.C is poured into the crucible 1 made of the stainless steel and further gas 3 such as gaseous Ar is forced into the crucible 1. The molten meal 2 thereof is then ejected from a nozzle 4 provided to the bottom of the crucible 1 and is quickly cooled on the surface of the roller 5 made of the Al or Al alloy, etc. The tape 6 of the Mg or Mg alloy is continuously formed on the surface of the roll 5 by the above-mentioned method. Since the gaseous Ar 3 is used, the oxidation of the Mg is prevented and the ejection of the molten metal 2 is made easy. The length of the tape is thus made longer and the generation of pinholes, etc. is prevented, by which the quality of the tape is improved.

Filed: 1989-06-29
Abstract: PURPOSE:To improve measuring accuracy by applying reaction received at the time of braking rotation to a target solid in the forward or reverse direction of rotation without stopping the rotation of a fly-wheel rotated by inertia. CONSTITUTION:After rotating the fly-wheel 20 at a rated rotational speed after operating a controller C, a current flow is interrupted to rotate the fly-wheel only by its inertia. Then, the rotation of the fly-wheel 20 is braked in the forward or reverse direction by operating the controller C in a range where the initial rotational inertia is not sharply attenuated like pulses or continuously. When the rotation of the fly-wheel being rotated by its inertia is controlled by the controller C, its reaction is generated in a stator 14, the reaction of control is transmitted to ground surface S and only the SH wave is generated on the ground. Thus, the measuring record of an S wave having a large SN ratio can be obtained.
