Abstract: A road marking device comprises: a tubular, bottomed casing which has an open top end; a cover mounted over an opening in the casing and having a window; a self-luminous marking system composed of a condenser housed in the casing, an illuminant which emits light by receiving a power supplied from the condenser, and a circuit for driving the illuminant; and a transparent element which transmits and outwardly radiates the light emitted from the illuminant. The transparent element is fixed between the cover and the casing which cooperatively hold a periphery of the transparent element, with a part of the transparent element protruding outwardly from the window in the cover. In a self-luminous marking system, an LED is utilized without application of voltage so as to detect the quantity of light in the road environment and to generate an electromotive force in response to an incident light. Based on the electromotive force generated by this LED, the drive of a display LED is controlled.

Abstract: The stretch wrapping machine employs a touch panel input device as input means for setting the film wrapping data into the controller, and the display of the touch panel input device provides digital presentation of the information on set values of the film wrapping data or a machine failure. Wrapping conditions (e.g. feed rate of the feed mechanism, control amount of the feed roller, rotation ratio of the feed roller to a stretch roller) can be automatically computed simply by entering film wrapping data on the number of wraps on the load, the film overlap amount, the film wrapping tension or the film stretch ratio, etc. The film wrapping operation is performed based on the computated conditions. The wrapping machine further comprises a load detection unit for detecting a load which is imposed on a film fed out from the feed roller onto an article.

Abstract: The present invention relates to: a packaging strap coil and its production method, wherein the innermost strap end is securely fixed to prevent un-winding thereof and the strap can be smoothly drawn out to the innermost end for strap-packaging of an item; a packaging strap coil unit which prevents deformation of the strap coil; and a packaging machine. The strap coil 11 comprises a number of layers of a resin packaging strap 11a wound helically and carelessly around a hollow 11b defining the axis of the strap coil 11. The strap 11a is made of a thermoplastic resin at least on its external surface. In the strap coil 11, a plurality of perforations 11d are pierced in the vicinity of an innermost end of the strap 11a through to a plurality of laminated layers. Each perforation 11d provides a melt-bonded area 11e along its periphery to bond the laminated layers of the strap 11a together.

Abstract: The following constitution is employed for enhancing the visual recognition of a road traffic sign by presenting a road traffic sign composed of a solid pattern having shades as visual image. A marking pattern divided into plural sections is tightly formed on the road, and the adjacent sections are mutually different in lightness, so that, in the road traffic sign of the invention, a solid figure is recognized as the visual image of the marking pattern. Herein, the adjacent sections have a lightness difference of 1 or more in Munsell value, and the lightness of each section is selected at lightness in two to four stages set at mutually different Munsell values. Moreover, when the adjacent sections are colored in hues mutually different in lightness, a more solid visual image will be obtained due to the difference in hue among the sections.

Abstract: A packing band having a superior weld is disclosed. The band can be made of a stretched thermoplastic resin having a flat cross section. The weld is formed by overlapping ends of the band extending in the lengthwise direction thereof. The weld portion of the band includes a plurality of welded sections separated by at least one non-welded section along the lengthwise direction of the band. The welding of the packing band can be accomplished by overlapping parts of the band in a lengthwise direction thereof; melting discontinuous portions of the parts in a pattern along the length of the band parts of a melted portion, an unmelted portion and a melted portion; and then pressing the parts together so that the melted and unmelted portions of the parts contact each other and form a weld.

Abstract: A tool for frictionally welding and binding art overlapped part of thermoplastic strap wound about an object by an vibrator.

Abstract: A self-straightening tape measure which is commonly called a convex rule, has hitherto been prepared exclusively of steel, however, the tape measure of steel is not only liable to be rusted but also is dangerous owing to good conductor of electricity when used in the vicinity of electric wires. In order to eliminate the above disadvantages, the present invention provides a self-straightening tape measure of resin, which is prepared by impregnating a tape material of crossing fibers with a large amount of thermosetting resin, bending the tape material in the width direction to form an arc in cross section, so that the arc may occupy from one-third to three-fourths of the whole circumference of the circle described by extending the arc, and heating the tape material to harden the resin and to have the said arcuate form.
