Title: Spark plug and its manufacture
Inventor: SUGIMOTO MAKOTO
IPC: H01T21/02
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a spark plug for which its insulator is covered with a glazed layer that can be glazed at a relatively low temperature and has a high insulating property. SOLUTION: In this spark plug 100 having a resistor, its glazed layer 2d formed on the surface of an alumina-based insulator 2 has a composition containing 18-35 wt.% of SiO2, 25-40 wt.% of B2O3, 10-25 wt.% of ZnO, 7-20 wt.% of BaO, 3-9 wt.% of Na2O, and 3-9 wt.% of K2O. This glaze hardly causes a crack or the like because the difference between its linear expansion coefficient and that of the alumina-based insulating material is relatively small. In addition, it has a softening temperature lower than that of conventional lead silicate glass, so that the glazing temperature can be lowered to 800-950 deg.C, and oxidation in a central electrode 3 or a terminal metal fitting 13 hardly occurs even when the glazing is carried out simultaneously with a glass sealing process.  Although its content of the alkaline metal constituent is high, it has a good insulating property and is excellent in flashover resistance.

Title: Foreign-matter inspecting apparatus
IPC: H01L21/66
Filed: 1992-03-31
Abstract: PURPOSE:To detect the foreign matter in a fine pattern by casting the S-polarized laser beams having the different wavelengths on one point of a wafer, separating the scattered light for every wavelength with a dichroic mirror, separating the light for every polarizing component, and obtaining the intensity ratio of S-polarization. CONSTITUTION:An S-polarized laser beam 14 having the wavelength lambda1 and an S- polarized laser beam 17 having the wavelength lambda2 are cast on one point of a wafer 18. The scattered light is condensed by an objective lens 19. The light is separated into the scattered light having the wavelength lambda1 and the scattered light having the wavelength lambda2 by a dichroic mirror 20. Then, each scattered light, which is separated for every wavelength, is separated into the P-polarization component and the S- polarization component with polarization beam splitters 21 and 22. The intensities of the S-polarization components are converted into the electric signals with photoelectric converter elements 23 and 24. The signals are outputted into signal processing devices. The signal strength ratio of the elements 23 and 24, i.e., the ratio of the S-polarization intensities, is discriminated with a suitable threshold value. Thus, the pattern edge and the foreign-matter are judged, and the fine foreign matter in the fine pattern can be detected.

IPC: H02P6/20
Filed: 1978-06-26
Abstract: PURPOSE: To enable stable and exact starting of a brushless motor of type for detecting the position by speed electromotive force by detecting back electromotive force of the motor to thereby switch the synchronization of the motor.  
     CONSTITUTION: When a brushless motor is started, the input voltage of a voltage- controlled oscillator 10 is controlled to thereby gradually raise the drive frequency of an inverter 1 to thus accelerate the revolving speed of the motor 2. When the motor 2 reaches the speed that the position of the rotor may be detected by its back electromotive force, a signal is produced from a comparator 11 to shut off the gate signal from the inverter 1 at an inhibit circuit 15 to thereby stop the inverter 1. The induced voltage of the motor 2 is detected during the stopped period of the inverter 1 to synchronize it with the induced voltage of the motor 2 upon detection of the induced voltage to thereby restart the inverter. After the restarting of the inverter 1, the motor 2 is operated by the output of the position detector 3 of the type for detecting the back electromotive force.

Abstract: PURPOSE:To obtain the polarization nondependent optical switch which has small loss and short device element length by making the width of the optical waveguide of an optical incidence part consisting of a curved optical waveguide larger than the width of the optical waveguide of an optical coupling part. CONSTITUTION:When the width W2 of the optical incidence part 2b consisting of the curved optical waveguide 2 is made larger than the width W1 of the optical waveguide 2 of the optical coupling part 2a and the optical waveguides 2 of the optical coupling part 2a and optical incidence part 2b are formed with a specific Ti diffusion quantity, the equivalent refractive index of the optical waveguide of the optical incidence part 2b is larger than that of the optical waveguide of the optical coupling part 2a, so light is confined more to the optical waveguide 2 of the optical incidence part 2b in light wave mode than to the optical waveguide 2 of the optical coupling part 2a. The loss of the light wave mode at the curved optical incidence part 2b is reduced as compared with a case wherein the optical coupling part 2a and optical incidence part 2b have the same width W1. Further, even if the curved optical waveguide is curved sharply, a low-loss optical incidence part 2b is obtained, so the device element length of the optical switch is reducible.
