Title: Pn junction type photodiode
Inventor: OKAMOTO KAZUYA
IPC: H01L31/10
Filed: 1986-11-12
Abstract: PURPOSE:To effectively generate a photocurrent and to increase sensitivity of short wavelength light, by forming a P-type semiconductor layer of that of high concentration and that of low concentration in a PN junction photodiode and making the PN junction small in depth. CONSTITUTION:A P-type semiconductor layer is formed of P-type semiconductor of high concentration and that of low concentration, and the PN junction is made small in depth. When short wavelength light L becomes incident, minority carriers optically generated in the first P layer 5 move effectively to the second P layer 6 caused by an electric field Ex formed in the first P layer 5. Namely electrons move easily in the direction of an arrow A. Concerning the second P layer 6, its concentration is lower than that of the first P layer 5, and its carrier recombination speed is small, and its life time is long in the order of mus. Therefore, carriers drift to a depletion layer 3 and go through the junction part, and so that photocurrent is generated.

Title: Sample stand of scanning type electronic microscope
Inventor: KURODA KATSUHIRO
IPC: H01J37/20
Filed: 1987-10-28
Abstract: PURPOSE:To make secondary electrons on the bottom of a deep groove hole emitted on a surface of a sample without impinging on side walls of the groove hole and to enable the effective detection of these emitted secondary electrons, by applying a negative voltage to the sample and besides disposing a lattice- shaped electrode in the vicinity of a surface of the sample. CONSTITUTION:A sample stand 8 is made of a metal and so a holder 82 is disposed thereon with an insulation spacer 81 in between, and a sample 3 is mounted on this holder. Further, a lattice-shaped electrode 84 is mounted on the sample stand 8 with a thin insulation spacer 83 in between at a surface side of the sample. Although the electrode 84 is biased at an earth potential and a negative voltage 9 is applied to the holder 82 from the outside of the vacuum, a small voltage can be used to apply a large electric field there because the spacer 83 is thin. Since the sample stand 8 of such composition is disposed inside the lens 5, even secondary electrons generated on the bottom of a deep groove hole are emitted from the surface of the sample and made to pass through a magnetic pole 51 and detected by a detector 4 when electron beams 1 are radiated on the sample 3.

Title: Checking method of contact gear pattern of gear
Inventor: HIRAOKA MINORU
IPC: G01M13/02
Filed: 1989-10-19
Abstract: PURPOSE:To reduce costs of a checking system and to shorten the checking time by obtaining the degree, strong or weak, of the contact between tooth surfaces and a figure corresponding to the gear contact pattern from an infrared image of the tooth surfaces when the gears are meshed with each other. CONSTITUTION:An image of the tooth surfaces corresponding to the degree of the contact between the tooth surfaces of a gear 10 and the gear contact pattern is picked up by an infrared camera 15. The infrared image is smoothed by an image processing apparatus 17 and a constant temperature line for every predetermined time interval is obtained from the smoothed infrared image. Then, a temperature inclination is obtained from the constant temperature line, based on which the gear contact pattern is evaluated. As the temperature inclination becomes sharper, an excessive load is more and more impressed to the subject part of the gear, causing a problem from the viewpoint of the strength. Therefore, for example, if the temperature inclination of the gear exceeds a predetermined value (reference value), the gear is judged as NG. Accordingly, it becomes unnecessary to apply a paint on the tooth surface or provide an illuminating device for the tooth surface, whereby the checking system is reduced in cost and the checking time is shortened.
