Title: Rectifying circuit
Inventor: SAKAI EIJI
IPC: H03K17/73
Filed: 1993-11-12
Abstract: PURPOSE:To make possible an increase in switching frequency and the miniaturization of a switching power supply by shortening the turn-off time of rectified currents by using a rectifying circuit as a rectifying circuit for an output from the transformer of the switching power supply. CONSTITUTION:In a switching power supply, a rectifying circuit is composed of a capacitor C1, diodes D11, D12, and switches Q1, Q2, and the switches Q1, Q2 are turned off simultaneously at the time of the turn-off of forward currents. The switches Q1, Q2 are turned off simultaneously while forward currents remain blocked. Consequently, when forward currents are turned off, rectified currents are commutated by the resonance of the leakage inductance L1 of a transformer for the switching power supply and the capacitor C1 for the rectifying circuit and the commutation time of turn-off is shortened, to make possible an increase in the switching frequency and the miniaturization of the switching power supply. Charges stored in the capacitor C1 are discharged to the input side through the switches Q1, Q2 while forward currents remain blocked, and provided for the turn-off of the next period.

Title: Method and apparatus for measuring thickness of running film
Inventor: YASUDA ATSUSHI
IPC: G01B7/06
Filed: 1998-10-22
Abstract: PROBLEM TO BE SOLVED: To make measurable safely and a highly accurately using simple facilities, by moving a magnetic material-made true spherical body in a direction perpendicular to the run of a film to detect the change of the magnetic field intensity while the spherical body put on a film top face is attracted by a magnetic field generating contact at a lower face. SOLUTION: When a magnetic field generator generates a magnetic field, a magnetic field is generated from a contact 3 to magnetically attract a steel ball 2. When the contact 3 is moved along a rail 4, the ball 2 being attracted to the contact 3 rotates to follow up the contact. If a film 1 has a nonuniformity in thickness, the difference appears in the magnetic field intensity between the ball 2 and contact 3, a magnetic field measuring means electrically connected to the contact 3 continuously measures the magnetic field intensity to detect its change, thereby measuring the thickness of the film 1. This method has no need of a special apparatus or space and makes the calibration before measurement very simple.

Filed: 1993-11-26
Abstract: PURPOSE:To provide a method for evaluating the life time through temperature acceleration test in which the acceleration test can be finished in a short time under ruptured state of actual machine and a linear relationship can be obtained with respect to the creep rupture time. CONSTITUTION:Since a creep brittle materials is not subjected to the fluctuation of test temperature, creep test is performed for a sample sampled from a part to be evaluated at a plurality of test temperatures higher than the working temperature of an actual machine thus determining a relationship between each test temperature and the creep rupture starting time. The results are extended linearly and the creep life time at a required machine temperature is determined. In case of a creep ductile, relationships are determined between the test temperature and the creep rupture starting time and breaking elongation while taking account of the fluctuation in test temperature. The results are extended linearly to determine the breaking elongation at actual machine temperature which is then corrected by the ratio to the breaking elongation at each temperature thus determining the rupture time at each test temperature. The corrected rupture time is extended linearly to determine the creep life time at actual machine temperature.

IPC: G01N27/04
Filed: 1995-11-14
Abstract: PROBLEM TO BE SOLVED: To obtain an inspection method in which the unstable electric breakdown of an insulating film can be detected by a method wherein the high-frequency component of the output of a gas-sensitive film is detected and, when its value is at a threshold value or higher, the insulating film is judged to be damaged. SOLUTION: The frequency of the dielectric breakdown of an insulating film is related to the composition of the insulating film, and the frequency of the dielectric breakdown is high in an Mg-free glass which is important in enhancing the durability of a gas-sensitive film. The dielectric breakdown can be detected by measuring the insulation resistance of a heater film, but the dielectric breakdown which is unstable appears as the high-frequency component of a sensor output. Then, when the high-frequency component is detected, an unstable insulation range can be detected.  In its detection, the waveform of the sensor output due to pulse heating is observed by an oscillograph or the like, the output is A/D-converted, the difference between the moving average of the output and the output is added up, or the output is Fourier-transformed and processed, a frequency is analyzed, and the component is detected. A heat-insulating glass film 4 and the heater film 6 are formed on an insulating substrate 2. The insulating film 12 is constituted of a lower layer 13 and an upper layer 14. In the inspection, the insulation resistance of the heater film 6 and the gas-sensitive film 16 is measured, and the insulating film can be judged to be defective when a measured value exceeds a threshold value.
