  • Patent number: 5945202
    Abstract: The invention provides an ink-oozing plate for a stamp with an ink-impregnated part having stamp-ink impregnable open cells, where the printing face of the stamp comprises a stamp ink-oozing part and a stamp ink-non-oozing part, where the stamp ink-non-oozing part is concave and is 0.01 mm or more lower than the ink-oozing part, the stamp ink-non-oozing part being made of a stamp material-molten part and a penetrating molten-mixing part where a heat-fusing substance penetrating part and a stamp material-molten part are present together.

  • Patent number: 5878668
    Abstract: On the surface of an ink-permeable sponge material having open cells, a melted portion and an unmelted portion are formed by a thermal head printer controlled by a memory processor for desired imprint data to prepare a stamp having the unmelted portion as an ink oozing imprint surface. Furthermore, a stamp material plate comprising the tape-like sponge material is wound up in the form of a roll and then received in a cassette case, and a stamp material cartridge comprising this cassette case is mounted in a cartridge receiving section of the thermal printer capable of printing in a tape form. A print image set by input from a keyboard or external input is printed on the stamp material comprising the sponge material fed from the cartridge by the thermal head, while the stamp material is pressed, to form a concave having a depth of 0.01 mm or more, thereby preparing a print plate for a stamp having a suitable length.

  • Patent number: 5691102
    Abstract: A process of producing an ink-oozing plate for a stamp having open cells, in which the production steps and the apparatus are simple, and an ink-oozing plate for a stamp which can provide a sharp impress image and is conveniently used, including such a method as using an exothermally fusible sheet coated with a heat-fusing substance which generates heat by irradiating with infrared rays and can penetrate into a stamp material, irradiating with infrared rays while pressing the stamp material, and coating an impress image copy with a liquid substance containing water, and thus coming to complete the process of producing the ink-oozing plate for a stamp of the present invention.

  • Patent number: 5669299
    Abstract: A cartridge containing a thermosensitive stencil original comprising a tape-formed thermosensitive stencil original which is to be perforated to create a print image, a pressing member for pressing the thermosensitive stencil original, and a cassette case having the pressing member disposed therein. The thermosensitive stencil original is also accommodated inside the cassette case so that the stencil original may be carried out from the cartridge. The mirror image of the desired print image is perforated onto the surface of the thermosensitive stencil original.

  • Patent number: 5611279
    Abstract: A stamp and a process of producing a stamp includes a stamp that is made from a sponge having open cells to allow repeated impressing operations without supplying stamp ink for a long time. The process includes fitting a heat-fusing ink sheet or a heat-generating plate, which contains a heat-generating material, over the surface of a stamp-piece that has open cells therein. A liquid substance soaks a manuscript having characters, patterns, etc., which are represented by non-applied areas of recording material. The manuscript is placed over the top in such a manner that an image may appear to be a mirror image. The manuscript is irradiated from above with light to cause light to pass through the non-applied areas of recording material to increase the temperature of the heat-generating material at sites corresponding to the non-applied areas of recording material.

  • Patent number: 5040219
    Abstract: A sound reproducing apparatus is capable of reproducing a stereo or a voice signal and adding thereto effect sounds, such as an initial reflected sound, and reechoed sound during the reproducing. Each of the effect sounds is added with a delay time depending on a change of the sound source signal. To obtain the delay time, the sound source signal is converted into a three-value signal, and then the time in which the auto-correlation of the three-value signal decreases to a predetermined value is determined. Thus the effect sounds can be added automatically with a desired delay time due to the sound source signal. Therefore manual adjustments are unnecessary, and the circuit structures of the entire apparatus can be simplified.

  • Patent number: 5033894
    Abstract: A knock-out type mechanical pencil which comprises a lead containing tube in which the inner and outer walls thereof are so tapered that the lead inlet thereof is larger in diameter than the opposite end thereof. The mechanical pencil further comprises a spring supporting ring interposed between the clamping ring so attached to the outer periphery of a chuck portion integrally formed with the lead guide of the lead containing tube and spiral springs to oppose with the base end of the ferrule within the outer barrel for urging the spring supporting ring to the ferrule. Thus, this mechanical pencil can eliminate the lead jams in the lead containing tube and lead breakage therein.

  • Patent number: 4843986
    Abstract: When two stitch lines parallel with the hem of a workpiece are stitched by a multi-needle sewing machine, a thread feeding apparatus positively feeds threads to each needle in proportion to the radius of the stitch line curvature such that well-balanced stitch lines are performed. Sensors located adjacent to said needles, and CPU (Central Processing Unit) operate cooperatively to drive each stepping motor which positively feeds the exactly required stitch length to each needle.

  • Patent number: 4654035
    Abstract: An injector such as a hypodermic syringe and the like is improved in that an amount of injection each time thereof is mechanically determined by provisions of a stopper disconnectably attached to the barrel of the plunger and a plurality of convex/concave portions provided integrally on the outer surface of the plunger and cooperating with the stopper so that the stopper acts as a limiter for an advancing movement of the plunger in the cylinder of the injector to determine the amount of each injection of the injector.

  • Patent number: 4352580
    Abstract: A knock-out type mechanical pencil has a supporting rod mounted with an eraser at its rear end and axially slidably engaged within the interior of a cylindrical knock-button. A tubularly cylindrical weight is axially slidably engaged around the supporting rod. A cylindrical magnet is axially magnetized and secured to the inner peripheral surface of the knock-button. An annularly inwardly raised guide portion is formed on the inner peripheral surface of the knock-button for guiding the weight to the axial line of the knock-button when the weight is axially slidably dropped downwardly toward the writing tip of the pencil. To protrude and fix an eraser from the rear end of the tubular cylindrical body, the rear end of the pencil is tilted downward. To automatically contain or retract the eraser in the knock-button, the writing tip of the pencil is directed downwardly in writing state.
