Title: Production of steel sheet for easy-to-open can having excellent openability
Inventor: SHIMIZU KEIICHI
IPC: C21D8/02
Filed: 1983-12-05
Abstract: PURPOSE:To obtain a steel sheet for a titled can having excellent openability by regulating the secondary cold rolling rate after hot rolling, primary cold rolling and annealing which are intermediate stages for producing a steel sheet for an ordinary can in a specific range from the relation among the hardness, content of C and cleanliness after annealing. CONSTITUTION:The above-described secondary cold rolling rate R is regulated by the equation and is made into the range of R<45 then hot rolling, primary cold rolling, annealing and secondary cold rolling which are intermediate stages for the steel sheet for the can are successively accomplished. Hardness H in this case varies with an annealing method (box annealing, continuous annealing, etc.), annealing conditions (temp. and heating and cooling conditions) and steel components and is generally in a 40-65 range in HR30T hardness. The content of C can be adjusted in a <=1,300ppm range with the steel plate for the can according to the decarburized state of the molten steel or the presence of absence of decarburization annealing in the intermediate stage. The resulting steel sheet for the easy-to-open can has good openability even if the residual thickness of a score is the same and further the reduction in the residual thickness of the score is made possible.

Title: Lighting device for discharge lamp
Inventor: SATOMI AKIRA
IPC: H02M7/12
Filed: 1990-08-28
Abstract: PURPOSE:To prevent a discharge lamp from its burn-out and miniaturize component elements of a lighting device and enhance reliability by raising the output voltage of a chopper circuit when lamp voltage is found to be raised according to the output of a lamp voltage detecting circuit. CONSTITUTION:During normal lighting of a discharge lamp at which lamp voltage VLA is low, a voltage at the connecting point of a diode D2 and a condensor C2' is lower than a reference voltage Vref and hence the output of a comparator IC2 is at low level and a transistor Q2 is off. Therefore a voltage obtained by division of a chopper output voltage VDC is sent to a control circuit 4 and the voltage VDC is set at a voltage V1. When the voltage VLA is raised and a voltage at the positive input terminal of the comparator IC2 is raised to above the reference voltage Vref of the negative input terminal of the comparator IC2, the output of the comparator IC2 is set to high level and the transistor Q2 is kept turned on. Thereby a resistance R12 is connected in parallel to a resistance R10 and the voltage input to the control circuit 4 is lowered. The voltage VDC is thus heightened to a voltage V2.

Abstract: PROBLEM TO BE SOLVED: To pick up the image of the positional distribution of various kinds of elements existing on the surface of a substance and a thin film accurately and quickly for analysis by providing an angle dispersion-limiting means at the substance and the limiter for limiting the angle dispersion of fluorescent X rays and bringing the detector and the limiting means closest to the substance. SOLUTION: A collimator plate 1 of an angle dispersion means and a camera 2 are installed immediately above the closest distance of a sample 3 and the rear proximity position of the plate 1, respectively. Monochromatic radiation light X rays of a synchrotron radiation light source are used as an X-ray source 4. After X rays pass through a slit 5 and a double crystal monochrometer 6, a light path width in a horizontal direction is limited by a slit 7, X rays pass through an incidence intensity detector 8 and are totally reflected on the surface of the sample 3 at a small angle, the angle dispersion of fluorescent X rays being generated near the surface of the sample 3 is limited by the plate 1 and an image is picked up by the camera 2. At this time, since the plate 1 is the fine tube assembly of glass, the angle dispersion of small fluorescent X rays is limited.  An image is picked up quickly for analysis by this kind of X-ray image pick-up analysis device.

Title: Fuel cell fluid floating plate
Inventor: DEBITSUDO ESU WATOKINZU
IPC: H01M8/10
Filed: 1990-08-30
Abstract: PURPOSE: To prevent water from being collected in a groove to form dead points in various areas over the whole plate, which deteriorates the gas flow distribution on positive electrode side by making the groove cross the main central, area of the surface as a plurality of passages. CONSTITUTION: A fluid flowing field plate 13 adjacent to a negative electrode 16 supplies a fuel, or a gas rich in hydrogen in this case to a negative electrode 16, and a fluid flowing plate 12 adjacent to the positive electrode 18 supplies an oxidizing agent (pure oxygen or air) to the positive electrode 18. A plate, thus, one continuous groove 22 crossing the surfaces of the adjacent electrodes 16, 18 as a plurality of passages of alternately arranged narrow long passages and short passages is used, whereby the approach of proper fuel and oxidizing agent gas to the substantially whole surface of the negative electrode 16 and the positive electrode 18 is ensured. Since the formed water is thus surely carried through the groove by the gas flow and discharged from a battery, no dead point by collection of water is formed on any part of the positive electrode operating surface.

Title: Method and apparatus for power management in network of computer station
Inventor: FURANKU DEIA
IPC: G06F15/177
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To provide improved energy saving characteristics for the computer station which is connected by the network. SOLUTION: The frame address matching function of a network control unit is increased. In full power-on mode, the control unit performs ordinary functions. In low power mode, the control unit includes functions for frame address and frame data matching and a specific and programmable autonomous response to the network. If a coincidence regarding a frame address or frame data is generated, a system related to the control unit is placed in a wake-up state. When the control unit is so programmed as to perform pattern matching in a frame data area, the control unit automatically generates and sends a simple response packet through the network if the said matching of the frame data is obtained. If the matching is not detected, on the other hand, no operation is done.

Filed: 1982-12-28
Abstract: PURPOSE:To increase the accuracy in the shape and size of a magnetic head and to make magnetic characteristic hardly deterioratable by providing at least one throughhole in the lamination direction of said head and packing an adhesive material in the through-hole. CONSTITUTION:Adhesive agents 18a, b, c, d are sealed in through-holes 17a, b, c, d. The shape of a core member 9 is preferably taken into consideration to determine the number, shape and position of the through-holes. When, for example, the member 9 is considered as a magnetic circuit, the magnetic resistance in the magnetic path near a winding window 19 is required to be made smaller than the magnetic resistance in a gap spacer part 14. The gap depth in the actual gap spacer part 14 is 30-50mu with, for example, a video head, and therefore the through-holes provided in the positions apart by 2-3 times of the window 19, that is, >=150mu, from said window by accounting for safety are satisfactory. In the case of the video head, the size of a head core is about 2mm.X2mm. and even if the through-holes of about 300mu are made, there is no problem in the magnetic circuit and no influence is given on the electromagnetic conversion characteristic thereof.
