Title: Composite grating lens
Inventor: OOGOSHI SEIICHI
IPC: G11B7/09
Filed: 1983-01-28
Abstract: PURPOSE:To obtain a composite grating lens which provides desired diffracted light with a simple construction and easy operation by forming grating-shaped ruggedness at a specified grating interval and step on one surface of a light transmittable base plate, and providing the ruggedness corresponding to the pattern of a Fresnel zone plate in superposition thereon. CONSTITUTION:Grating-shaped ruggedness 11 is formed at a specified grating interval and step on one surface of a lens base plate 11 consisting of an acrylic resin or PVC which is a light transmission medium and ruggedness 31 having the fine period corresponding to the pattern of a Fresnel lens plate is formed in superposition thereon. The step d1 of the ruggedness 31 is set at the value at which the optical path difference equivalent to 1/2 wavelength given by the following equation where the refractive index of the lens material is designated as n: d1=lambda0/2(n-1) is produced. If a light emitting source such as a semiconductor laser which can be regarded nearly a spot light source is placed in the focal position of the lens constituted with the pattern of such a Fresnel zone plate, the primary light of the light past the lens is diffracted to parallel luminous fluxes. Further, the ruggedness 31 is formed superpositively on a grating-shaped ruggedness 21 having a period A0, so that the light past the lens is converted to the diffracted light of 0 order and n-th order by a linear diffraction grating 21 and is at the same time converted to parallel luminous fluxes.

Title: Reflection preventive film
Inventor: MIYATA TAKEO
IPC: H03L7/093
Filed: 1983-01-27
Abstract: PURPOSE:To obtain a reflection preventive film which is highly resistant to environment, is less absorptive and is therefore usable for CO2 laser having high resistance to light power by forming an arsenic triselenide film, lead fluoride film and arsenic triselenide film in this order at specific thicknesses on a KRS-5 substrate. CONSTITUTION:The optical thickness of As2Se32 having a refractive index n3 of 2.8 is n3d3=2.15mum, the optical thickness of PbF23 having a refractive index n2 of 1.67 is n2d2=1.691mum and the optical thickness of As2Se34 having a refractive index n1 of 2.8 is n1d1=0.4883mum. These optical film thicknesses are determined to satisfy the relation of Mouchrat concerning a three-layered reflection preventive film. The respective materials are successively deposited by using a resistance heating vacuum deposition method on a KRS-5 substrate 1 to form the reflection preventive film consisting of the three-layered construction. The absorptivity of the three-layered reflection preventive film is lower than 0.05% of a single PbF2 layer having the lowest absorptivity among two-layered constructions. Said film has the higher resistance to environment than the single layered PbF2 reflection preventive film as PbF2 is protected by the As2Se3 film which is chalcogenide glass and is insoluble in water.

Title: Method for detecting defective insulator
Inventor: KIRISAWA TAKASHI
IPC: H01B17/00
Filed: 1989-01-20
Abstract: PURPOSE:To permit certain and easy detection of defective insulators all the time by computing the ratio of shared voltage of insulators to be measured to that of insulators adjacent thereto to judge defective insulators when the ratio of the shared voltage is less than an allowable value. CONSTITUTION:Good insulators has a property of shared voltage constant shown in the Fig. in terms of suspension insulators without arcing hone, however the insulators mixed with defective insulators has shared voltage lowered to make the shared voltage of the defective insulators smaller than that of the good insulators adjacent thereto, accordingly. So, the ratio of shared voltage of insulators to be measured to that of insulators adjacent thereto is computed to judge defective insulators when the ratio of the shared voltage is less than an allowable value. It is thus possible to detect defective insulators which are lowered to 100MOMEGA or less in insulation resistance, occupying 90% or more in total of defective insulators. As a result, if standard shared voltage property is not memorized for every measured insulator, defective insulators can be detected surely and easily with an unchangeable criterion all the time.

IPC: G11B11/10
Filed: 1984-01-26
Abstract: PURPOSE:To improve the C/N by providing two pairs of photodetectors consisting of two photodetectors having angles containing transmission axes having equal positive and negative polarizing directions, a differential amplifier which produces a difference signal from each pair of photodetectors which detects the transmitting light of the photodetectors and an arithmetic circuit which performs addition or subtraction of outputs. CONSTITUTION:Two pairs of photodetectors consisting of two photodetectors respectively are used to calculate two outputs which are detected differentially. For a photodetector pair A, photodetectors 42 and 43 form an angle theta to the polarizing direction 18 and the difference between both detectors 42 and 43 is defined as DELTAIA. While photodetectors 44 and 45 of a photodetector pair B form an angle theta' to the polarizing direction 17, and the difference between both detectors 44 and 45 is defined as DELTAIB. Then the difference between DELTAIA and DELTAIB is defined as I. Thus these differences are produced by a circuit shown in (c). The table 1 shows the output of a differential amplifier in a simple form. The maximum value is shown in the parentheses when theta=theta'=45 deg. is satisfied. The difference between H and L levels is defined as 8LthetaK from (d). This value is equal to double as much as 4LthetaK that is obtained by a conventional differential detection method. As a result, the C/N is increased.
