  • Patent number: 6249973
    Abstract: A mechanical thinning razor includes a shank, a handle, a blade, a bladeguard, a driving member and a sliding member. When pushing an external surface of the driving member toward a hollow midsection of the shank, the bevel of the driving member forces the sliding member to move longitudinally over a distance that corresponds to a width of exposed segments or non-exposed segments, thereby doubling the working life of the blade.

  • Patent number: 5938889
    Abstract: A tape feeding apparatus capable of feeding a tape laminate made by superposing a first tape having a first chemical material layer on one side and a second tape having a second chemical material layer on one side reacting with the first chemical material with the layers in contact with each other. When the chemical reaction occurs between them, the second chemical material layer exhibits an indication which is visually recognized. Rollers press the first tape drawn out from a first reel and the second tape drawn out from a second reel so that the first and second chemical material layers come in mutual contact, and form the tape laminate.

  • Patent number: 5722319
    Abstract: The present invention is directed to an apparatus which is suited for use by women, children and the like who have limited physical strength to continuously stamp embossed patterns with clear outlines with the same spacing. A press roller is provided with an embossed pattern stamping die on a circular external circumferential surface, with its rotating shaft supported by bearings at a specific position, and is caused to perform axial rotation by a rotating drive force applied from the outside. A receptacle portion faces opposite the external circumferential surface of the press roller, with its opposing surface constituted as a flat surface or a convex surface to form a gap between itself and the press roller where a sheet-like object to be stamped is to be inserted.

  • Patent number: 5553277
    Abstract: One unit of image/text information (a card) is formed from image information, which is for displaying respective ones of N--number of images, and text information, and a large number of cards are stored in a memory device to construct a data base. When search conditions such as a desired keyword or numerical range have been entered, at least one card which satisfies the search conditions is searched and retrieved from the data base by referring to the text information of each card. First images from each of the cards retrieved are reduced in size and then combined, the reduced and combined images obtained are displayed on a display device, and a desired item of image/text information is selected from the reduced and combined images.

  • Patent number: 4118780
    Abstract: A technique for monitoring the frequency difference between pulse output signals derived from a pair of flowmeters interposed respectively in the inlet and outlet lines of a flow conduit supplying cooling water to the tuyere of a blast furnace, the frequency difference being indicative of water leakage. The furnace has a plurality of such tuyeres, each conduit of which is monitored. The pulse output signals from the flowmeters at each monitoring point are fed to a common processing unit in which there are stored the constants representing the instrumental error between each pair of flowmeters as well as their mean conversion constants. In the processing unit, computations are carried out on the basis of the pulse output signals derived from each pair of flowmeters, the instrument error constant thereof and their mean conversion constants, in order accurately to determine the flow rate difference therebetween at each monitoring point independently of the instrumental error.

  • Patent number: 4090179
    Abstract: A system for monitoring the frequency difference between pulse output signals derived from a pair of flowmeters interposed, respectively, in the inlet and outlet lines of a flow conduit supplying cooling water to the tuyere of a blast furnace, the frequency difference being indicative of water leakage. The pulse output signals produced by the respective flowmeters during each predetermined measuring period are integrated. The integrated values are compared with each other, the difference therebetween being monitored whereby when the difference exceeds a predetermined set value, an alarm is generated.
