IPC: H02P8/12
Filed: 1987-05-26
Abstract: PURPOSE:To perform constant current drive even in high speed rotation of a step motor, by generating the voltage in proportion to the frequency of an input clock. CONSTITUTION:The frequency of a clock is converted into voltage with a frequency/voltage converter 5. The output voltage is amplified with an amplifier 6 and the amplified output V(f) is subtracted from a reference voltage V'ref with a subtractor 7, of which the subtracted output V'ref-V(f) is let to be a set voltage Vref of a subtractor 3.

Filed: 1993-05-31
Abstract: PURPOSE:To obtain a method and device for processing a waterless planographic printing plate by which the flow resistance and the printing durability of the waterless planographic printing plate after plate making are improved. CONSTITUTION:A stage for immersing a photosensitive layer in a compound infiltrating a non-image part or water solution containing the compound and having low water content in comparison with water-based developer is provided before or/and after coloring stage after finishing a developing stage.

IPC: B21J5/10
Filed: 1993-05-31
Abstract: PURPOSE:To prevent the occurrence of surface faults when a cut material is forged in the axial direction and formed in an annular forging plate. CONSTITUTION:Surface faults 21a, 21b caused on projecting and recessed parts existed on the cutting surface of a cut plate are existed on the surface of a 1st disk-like metal plate 21 that metal wire is cut in a specific length and the cut plate is formed with forging in the axial direction.

Title: Improvement of secondary adhesion of paint film on zinc plated steel sheet
Inventor: GOTOU MINOSHIGE
IPC: C25D5/26
Filed: 1982-07-26
Abstract: PURPOSE:To form a dense, fine and uniform phosphate film and to improve remarkably the secondary adhesion of a paint coated film, by applying plating of a limited thickness on zinc plating with an iron plating soln. contg. a specific amt. of tin. CONSTITUTION:Fe and Sn are electrodeposited at 0.01-10g/m<2> total on a zinc plated steel sheet from an aq. soln. contg. Fe<2+> and Sn<2+> within a range of <=0.2 (Sn<2+>/Fe<2+>+Sn<2+>). Or Fe is electroplated at 0.01-10g/m<2> on said steel sheet and in succession Sn is electroplated or electroless plated at about <=1g/m<2>. Then, Sn deposits on the part where the Fe plating layer is imperfect so as to coat thoroughly the base zinc, and since a slight amt. of deposited Sn increases the number of nuclei for generating a phosphate crystal, the purpose is presumably achieved. Thus the slight amt. of the deposited Sn is effective and if said amt. is too large, the nonuniform phosphate treatment is resulted.

Title: Photodetector
Inventor: ASAHINA MAMORU
IPC: G01J1/02
Filed: 1982-07-26
Abstract: PURPOSE:To detect a position of a photodetecting image extending over a wide range on a photodetecting face by simple processing, by combining two comb-shaped photoelectric elements so as to be meshed with each other, and varying linearly extending from the tip part to the base part with respect to sensitivity to light per unit length of a part corresponding to a tooth of a comb shape. CONSTITUTION:In figure, 3, 4, and 5, 6, and 7 denote comb-shaped photoelectric elements, a part of the photoelectric elements 3, 4 corresponding to a tooth of a comb shape, respectively, and an example of a photodetecting image, respectively. The teeth 5, 6, of the comb shape have a wedge shape in this example, and vary sensitivity of each length of the tooth. As a photoelectric element used in this case, if the intensity of illumination is the same, when an element which obtains an output being proportional to a photodetecting area is selected, an output of each photoelectric element 3, 4, by the image 7 is in proportion to an area for receiving an image of the parts 5, 6 of each tooth. If an interval of the teeth 5, 6 of the comb shape is sufficiently narrower than size of the image, the part irradiated by light of each tooth is regarded as a trapezoid by disregarding a bend of both end parts, therefore, its area becomes the product of the part irradiated by light and width of the tooth in the center part of the image.

Title: Converting apparatus of flow rate
Inventor: UCHIYAMA YOSHIFUMI
IPC: G01F5/00
Filed: 1988-05-26
Abstract: PURPOSE:To make it possible to measure a flow rate in a vibration-free and stable manner in the wide range of the flow rate, by a construction wherein a hole for introducing a fluid to be measured, which is larger than the opening of a hole for measurement, is provided on the upstream side of the hole for measurement and slender pipes for turning the fluid to be a laminar flow are provided in the former hole and a hole for bypass. CONSTITUTION:A cantilever-type pressure receiving plate 11 is warped by the flow pressure of a fluid to be measured which flows through a hole 9 for measurement. The amount of this warp is proportional to the flow rate of the fluid, and therefore the flow rate is measured by detecting the amount of the warp electrically by a detecting coil 12. On the upstream side of the hole 9, a hole 10 for introducing the fluid to be measured and a hole for bypass are provided, and a number of slender pipes 18 are provided in these holes. Accordingly, the fluid is made to be a laminar flow through the slender pipes 18, and thereby the generation of a vortex or the like is suppressed, no vibration being generated. Therefore the pressure receiving plate 11 can convert the flow rate into an electric signal in a stable manner. The slender pipes 18 act on a wide range of flow rates from small to large. By this construction, the flow rate can be measured in a wide range thereof in a vibration-free and stable manner.

Title: Oil-pressure circuit for oil-pressure shovel
Inventor: YOSHIMATSU HIDEAKI
IPC: E02F9/22
Filed: 1981-08-19
Abstract: PURPOSE:To permit the smooth turning of an oil-pressure shovel by a method in which a variable sequence valve is connected to the parallel pathway of a turning direction control valve so as to give priority to the turning circuit over the arm and boom circuits during period when turning arm and boom operations  are concurrently performed. CONSTITUTION:A variable sequence valve 40 is provided in the parallel pathway 32 of a turning direction control valve 21. In such a system, when the lever 51 of a turning remote control valve 50 is fallen down in the direction of arrow A, secondary pressure is directed even in the direction of arrow A3, the set pressure of the valve 40 is raised, and turning is accelerated by a turning motor M2. Then, the discharge oil of an oil-pressure pump P2 flows preferentially into the turning motor M3 and its excess oil is bleeded off by the valve 40 and directed into parallel pathways 34, 36, and 37 through the pathway 33. In short, when an arm control valve 23 is operated, said excess oil is directed in the direction of arrow A4 to actuate an arm cylinder C2. Thus, the operation of the arm cylinder C2 does not affect the operation of the turning motor M3.
