Title: Pantograph
Inventor: AOKI RIYOUICHIROU
IPC: B60L5/22
Filed: 1977-12-26
Abstract: PURPOSE: To return the current collecting shoe separated from a trolley wire to the original position in a pantograph by detecting the separated shoe between the pantograph and the trolley wire, when once separated, and lifting the shoe for predetermined time to thereby  increase the follow-up ability of the shoe.  
     CONSTITUTION: The contacting strength between a trolley wire 16 and a current collecting shoe 17 is detected by a poppet 24. When the shoe 17 approaches separation from the wire 16, the poppet 24 detects it to thereby supply hydraulic oil to a cylinder 19 of a shoe lifting unit during time determined by the discharging time of an accumulator 29 so as to lift a piston 23 telescoped with the cylinder 19. It excessively compresses a recoil spring 15 at a distance corresponding to the stroke of the piston 23 by means of the reaction of the piston lifted so as to increase the lifting strength of the shoe 17. Thus, the separated shoe 17 is returned to its original position so as to prevent an arc from occurring therebetween.

Filed: 1988-06-23
Abstract: PURPOSE:To reduce the fluctuation of the frequency characteristics of the reproduction output by forming an NiO thin film between a magnetic core base part and a ferromagnetic metallic thin film of a magnetic core. CONSTITUTION:An NiO thin film 6 is formed between a magnetic core base part 2 consisting of a ferromagnetic oxide film and a ferromagnetic metallic thin film 3 of a magnetic core 1. As a result, the soft magnetic properties of the film 3 can be improved at the initial part of formation of the film 3, i.e., a part near an interface between the film 3 and the film 6. Then the adhesive intensity is improved between the part 2 and the film 3. Thus the fluctuation is reduced for the frequency characteristics of the reproduction output. Furthermore it is possible to avoid such an inconvenient case where the film 3 exfoliates in the working process of a magnetic head.

Filed: 1979-12-05
Abstract: PURPOSE:To minitor a plurality of control operations that correspond to a pattern signal prescirbing more than one pattern by supplying the pattern signal from a controller to an operation monitoring device in the operation monitoring system for a sequence control system. CONSTITUTION:To permit input-output part 2 to be monitored to perform a plurality of operations, controller 1 exercises control that corresponds to patterns with control signal 4 for the input-output part to be monitored.

Abstract: PURPOSE:To allow the faithful binary recording of even the high space frequency component of a Fourie transform image by distributing the photoconductivity of a photoconductive layer symmetrically with a center in the plane and increasing the photoconductivity the further from the center within the plane. CONSTITUTION:Transparent substrates 1a, 1b consisting of glass, plastic, etc., for crimping liquid crystal molecules are provided with transparent electrode layers 2a, 2b and oriented film layers 3a, 3b on the surfaces. The photoconductive layer 5, a light shielding layer 6 and a ferroelectric mirror 7 are laminated and formed between the transparent electrode layer 2a on the writing side by light and the oriented film layer 3a on this electrode layer. The photoconductivity of the photoconductive layer 5 of the liquid crystal light valve is distributed symmetrically with the center in the plane and increases the further from the center within the surface and, therefore, the effective photosensitivity is higher the further from the center within the plane of the region irradiated with the Fourie transform images. The high-frequency components are eventually recorded with the higher sensitivity than the low-frequency components of the Fourie transform images. The exact recording of the high-frequency components of the Fourie transform images is possible in this way even if the light intensity of the high-frequency components of the Fourie transform images decreases drastically.
