Inventor: ADACHI KENJI
IPC: G01N23/227
Filed: 1991-10-23
Abstract: PURPOSE:To obtain a ratio of a glass mesh ornament body of Pb ion which is subjected to solid solution within a glass substance to a glass mesh constitution body by obtaining a relationship between a strength of a signal of Pb4f trajectory electron of lead ion which is obtained by the photoelectron spectral method and a combination energy and then by separating two peaks at a low-combination energy side out of four peaks which are observed in the signal strength. CONSTITUTION:A difference between a glass mesh constitution body and a glass mesh ornament body appears remarkably at a signal of Pb4f trajectory out of photoelectrons which are excited by irradiating X rays to a glass. A relation between a combination energy and a signal strength is obtained based on a signal of the Pb4f trajectory electron of lead ion which is obtained by the photoelectron spectral method according to a glass substance containing lead and two peaks at a low-combination energy side out of four peaks which are observed in the signal strength are separated into two peaks with a functional status to a fixed mixing ratio of Gauss function and Lorentz function. An integral strength ratio between two peaks is used as a ratio between the glass mesh constitution body and the glass mesh ornament body of Pb ion which is subjected to solid solution into the glass.

Title: Diagnostic apparatus for insulation of rotary machine
Inventor: YAMADA NAOYA
IPC: G01R27/02
Filed: 1989-11-22
Abstract: PURPOSE:To measure insulation resistance, a leakage current and tandelta by one measuring device by providing two kinds of threshold values to the measured value of insulation resistance and executing final charging and the transfer judgement to the measurement of a leakage current or the like on the basis of the respective threshold values. CONSTITUTION:When a test is started in a full-automatic mode, preparatory charging is performed at first by relatively low voltage to measure insulation resistance R1. When the value R1 is the first threshold value or more, final charging is performed. Preset DC voltage is charged in the final charging and, when the insulation resistance value R2 at this time is the second threshold value or more, a leakage current is measured. The measuring voltage of the leakage current in a full-automatic case is usually set same as Meg final charging voltage. Continuously, charged voltage is changed over from DC to AC by full-automatic control and voltage is allowed to rise and drop to preset upper limit voltage by a stepwise rising method and tandelta is measured at each voltage level. When the value R1 is below the first threshold value, the insulation resistance value is displayed and the test is interrupted. When the value R1 is below the second threshold value, the full-automatic mode is released to be altered to an individual automatic mode.

Title: Magnetic recorder
Inventor: SHINOHARA HAJIME
IPC: G11B5/02
Filed: 1987-12-02
Abstract: PURPOSE:To reduce the coefficient of friction between a magnetic head and a magnetic recording medium to prevent attraction of the magnetic head and the medium by setting the surface roughness of the floating face of the magnetic head and that of the medium to specific values or smaller. CONSTITUTION:When the surface roughness of the floating face of the magnetic head and that of the magnetic recording medium are denoted as R1 and R2, they satisfy R1>=20Angstrom , R2>=50Angstrom , and 70Angstrom <R1+R2<=2,000Angstrom . Attraction is actually caused though the surface of the recording medium is roughened in a certain degree if the surface roughness of the floating face of the magnetic head is <20Angstrom , and attraction is caused though the floating face of the magnetic head is rough if the surface roughness of the medium is <50Angstrom . If surfaces are too rough, projections or the like are locally generated to cause head crush or damage of the medium, and an average thickness of the medium is practically increased; and therefore, it is preferable that the sum R1+R2 of surface roughness of both surfaces is practically <=2,000Angstrom . Thus, the coefficient of initial friction is <0.7, and attraction is eliminated to obtain a magnetic recorded of high reliability is obtained.

Filed: 1995-10-30
Abstract: PROBLEM TO BE SOLVED: To control a power transient phenomenon by making a transient phenomenon suppression circuit start conducting at the time of connecting a disk and a power source or immediately after that, attaining a complete conducting state by the control of the transient phenomenon suppression circuit after the lapse of short time and disconnecting the impedance characteristics of a load from the power source by an interval for increasing the conducting. SOLUTION: When the transient phenomenon suppression circuit TSCa or TSCb is connected to the power source PS first, a power transistor Q1 or Q2 is turned OFF. When power source connection is completed, the conductivity of the power transistors Q1 and Q2 is increased as the function of time and a voltage connected to the disk is gently raised by time variable conductivity controlled by capacitors C1 and C2. When the power transistor is completely conducted, the power source finally encounters the impedance of the load of the disk receiving power supply directly from the power source. By taking the complete conducting timing of the power transistor, the impedance of the load is stabilized.
