Title: Method for using inverter
Inventor: NAKAJIMA KAORU
IPC: H02M5/14
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To make commercial single-phase AC power supply usable as the input power of an inverter, by using an inverter device having a relatively large capacity for a motor for three-phase power supply, in a system which variably controls the speed of the motor. SOLUTION: The converter section of an inverter device is constituted of a rectifying diode 11 and a capacitor 12, and rectifies alternating current inputted through R-, S-, and T-terminals into a direct current. The inverter section of the inverter device again generates AC power of an arbitrary frequency and voltage by making chopping by means of a power element 13, and outputs the AC power to U-, V-, and W-terminals. The converter section usually rectifies commercial three-phase AC power, but can rectify the AC power even when the converter section is wired in a single-phase state by eliminating the S-phase wiring shown by the dotted line in the figure. When the converter section is wired in the single-phase state, the input current becomes about 1.7 times as large as that in the case of the three-phase power supply when the AC output is the same.  Therefore, even when the inverter device for commercial three- phase AC power supply having such a allowable input current capacity that is increased by about 1.7 times is wired in the single-phase state, the inverter device can use commercial single-phase AC power supply within its power capacity.

Abstract: PURPOSE:To improve heat exchange efficiency, to reduce incurring of a loss of radiation from a heat exchanger during the stop of combustion, and to reduce an installation area by a method wherein a burner mounting part is disposed to the upper part of a heat exchanger for hot water and a discharge port to the lower part of the heat exchanger, and both primary and secondary heat exchangers are provided at the upper parts with respective piping connec tion parts. CONSTITUTION:Combustion gas burnt by a burner 24 is discharged to the outside from the interior of a combustion chamber 32 through a discharge part 34 by means of the interior of a discharge box 18, a discharge passage 33, and a discharge cover 16. Hot water flows through a return port 29 to a water passage 28 of a heat exchanger 27 and is heated by the heat exchanger 27, and is fed through a hot water outlet 31 to a given radiator. In which case, a water passage 28 in the heat exchanger 27 is disposed in a lateral U-shape in a manner to cover a combustion cylinder 15, a discharge box 18, and fine tubes 16 therewith. By arrang ing the flow of combustion gas and the flow of hot water in juxtaposition with each other, heat exchange efficiency is improved, and delivery of uniform high temperature water is practicable. By arranging the combustion chamber 32 and the discharge passage 33 vertically in two stages and forming combustion gas and the water passage 28 in a lateral U-shape, the width of a heat exchanger may be reduced. Since, by forming a hot water outlet 31 in the upper part of a secondary drum 20, the temperature of the upper part of a secondary outer drum is increased, formation of the hot water outlet in the upper part thereof enables the feed of high temperature water to a radiator.

Abstract: PROBLEM TO BE SOLVED: To provide a methodology for tracking the dynamic behavior of a single molecule functional polymer, or the like, on the order of atom or molecule. SOLUTION: In a sample for detecting the dynamic behavior of a functional biological polymer using a single molecule, a target molecule 6 is adsorbed onto an X-ray transmitting membrane 2 for holding the target molecule and a microcrystalline cluster 3 is labeled at the target position of the target molecule. At the time of measuring Laue diffraction, conditions for allowing function of the target molecule 6 are realized in two X-ray transmitting membranes 2, 5 so that a time sharing measurement can be carried out. Since variation in the direction of the microcrystalline cluster 3 labeled at some position of a functional polymer can be projected while being enlarged through Laue diffraction and detected, dynamic variation can be detected from a single molecule resulting in high speed measurement.
