Title: Surface defect inspection device
Inventor: EBISAWA KATSUHIDE
IPC: G01B11/30
Filed: 1992-04-17
Abstract: PURPOSE:To inspect change in recessed and projecting parts of a coated object and that in color and then eliminate scattering by mounting a differential interference lens with a specific magnification in front of a CCD camera for capturing reflection light fro an object to be inspected. CONSTITUTION:For observing a surface defect of an object 7 to be inspected such as a magnetic drum and an optical disk a CCD camera 1 is mounted so that the distance to the surface of the object 7 to be inspected is maintained to be constant. A differential interference lens 2 with a magnification of 5-400 or a bright visual field lens 3 is mounted as needed. It is desirable that a mercury-xenon lamp 5 should be mounted to maintain the brightness of the object 7 to be inspected to be constant. Also, it is desirable that a dichroic mirror 4 should be mounted in front of the camera 1 to examine the change in color. A signal from the camera 1 is guided to an oscilloscope 6, thus judging presence or absence of defect. At this time, the width of a reference value is determined previously and those above or below the value are determined to be defective.

Filed: 1995-04-24
Abstract: PURPOSE: To prevent that a switch element discharges, during off state, up to the voltage equal to or lower than one half of the DC power supply voltage by respectively connecting snubber circuit to a capacitor so that a voltage equal to one half of the DC power supply is applied thereto through a discharging resistor. CONSTITUTION: When a switch element T1 turns off, a surge current is bypassed to control a surge voltage applied on a switch element T1 . Only surge voltage is additionally charged in a snubber capacitor Ca and when charging is completed, the additional charges are discharged through the circuit of power supply E1 and resistor Ra and thereby voltage of capacitor Ca returns to one half of the power supply voltage. When the switch element 1 turns off, a current flows to the switch element 2 through a diode D11 . When the switch element T2 turns off, a surge current is bypassed from the neutral point 0 and the surge voltage applied on the switch element T2 is controlled. From the symmetrical structure of the circuit, the other switches T3 , T4 also operate in the same manner.

Abstract: PURPOSE:To make negative pressure act in a direction of drawing fuel in a throw jet or suchlike, as well as to improve the extent of speed persistence with a fuel feed function at time of engine low speed increased, by opening an air intake of a fuel increaser to an air chamber for air jet use. CONSTITUTION:With engine starting, fuel in a float chamber 40 is fed to an intake passage 32 of a carburetor 24 from a main jet and a throw jet 44. At this time, since a heater 68 of a fuel increaser 52 is not energized with current, a valve body 64 is opened upward. Then, a diaphragm 53 of the fuel increaser 52 is operated, and the fuel in the float chamber 40 is guided to a pump case 54 from an outlet 57 and then it passes through the circumference of a needle valve 62 and is discharged to another outlet 82. In this case, negative pressure being produced in an intake manifold 22 is transferred to an air chamber 74 via an increment fuel passage 84, the fuel increaser 52 and air passages 71, 72. Since it works in a direction of drawing the fuel from the throw jet 44, the fuel being supplied at time of low speed becomes somewhat thickish.

Abstract: PROBLEM TO BE SOLVED: To relax the field concentration on the ends of field plate electrodes, without comparatively increasing the thickness of an insulation layer by partly burying insulator plates between a first and second insulation layers beneath the ends of the field plate electrodes. SOLUTION: Non-doped polycrystalline Si-made insulator plates 8 are buried between a first and second insulation layers 5, 6 so as to raise the ends of field plate electrodes 7. This allows the thicknesses d1, d2 of the insulation layers between the field plate electrodes 7 and semiconductor substrate 1 to be increased away from p-n junctions 3 to outside diffused regions 2. If hence a depletion layer 10 is formed around the p-n junctions 3 to result in generation of an electric field, the field concentration at the ends of the field plate electrodes 7 can be relaxed to improve the breakdown field intensities at the p-n junctions 3 and the insulation layer beneath the ends of the field plate electrodes 7.
