This invention relates to the process for obtaining sheets made from seaweed that, when wrapped around a coal mine, wax mine or ink loads, give rise to the cylindrical and elongated cover of pencil or pen made based on algae, salt, bentonite and water, with a final layer of cotton thread optionally, tinctured with natural plant elements and having seeds at its rear end. The process for the production of films made from algae by heat treatment with the addition of salt and bentonite for making covers of pencil or pen comprises the following steps: i) boiling seaweed containing collagen for gelatinization together with salt and bentonite; ii) poring the gelatinized algae into the bowl and dip a graphite for writing; iii) subjecting to temperature for drying the algae and obtaining sheets; iv) cutting the sheets, according to the size of graphite for writing, leaving a space at the rear end to place the seeds; and iv) wrapping the graphite for writing with pieces of wet sheets to obtain a particular shape.

Articulated pens are provided. A pen includes: a shank; an ink tube comprising a first section, a second section, a third section, and a fourth section; a writing tip connected to the fourth section; a first guide rail connected to the shank and that bends the ink tube at a first angle between the first section and the second section; and a second guide rail pivotally connected to the first guide rail and that bends the ink tube at a second angle between the third section and the fourth section. Pivoting the second guide rail relative to the first guide rail adjusts a third angle between the second section and the third section.

A writing implement in which a joint connecting an ink supply section and a ballpoint pen tip together is configured from three members. The three members configuring the joint are a substantially cylindrical center member, a substantially cylindrical surrounding member formed at the outer periphery of the center member, and an interposing member that is molded by a soft member molded so as to cover the outer periphery of the center member and the surrounding member. An annular gap section is provided between the center member and the surrounding member. The leading end of the ink supply section is fitted into the gap section. The joint is formed by two color molding. The center member and the surrounding member are molded by primary molding, and the interposing member is integrally molded onto the center member and the surrounding member by secondary molding.

A method of coextruding polymeric materials into multiple layers of desired thickness to form a tubular workpiece. The method includes conveying a first polymeric material through a main extruder and a second polymeric material through a coextruder. The second polymeric material has dispersed therein an amount of electrically conductive particles effective to impart electrical conductivity to the tubular workpiece. The method further includes simultaneously extruding the first polymeric material and the second polymeric material through a coextrusion die to form the tubular workpiece. The tubular workpiece is extruded in the form of one or more outer layers having the first polymeric material and one or more inner layers comprising the second polymeric material. A tubular workpiece prepared by the method of coextruding polymeric materials into multiple layers of desired thickness. A system for coextruding polymeric materials into multiple layers of desired thickness to form a tubular workpiece is also provided.

A method for producing a partly transparent body with a color gradient, include: providing a transparent first casing having a first joint surface on a protrusion and including an encased object; providing a second casing which is not completely transparent and which has a second joint surface in a recess. The shape of the protrusion and the shape of the recess correspond to each other; and combining the first casing and the second casing by inserting the protrusion into the recess and melting the first joint surface of the first casing with the second joint surface of the second casing. A pressure force and a temperature are applied to the first joint surface and the second joint surface such that the first joint surface of the first casing transitions into the second joint surface of the second casing in a visually seamless manner, followed by a removal of material.

The invention relates to a component for writing, drawing, painting and/or cosmetic implements for receiving at least one application medium, the component comprising at least one sleeve, which is made of a polymer-bonded wood substitute substance and which has an inner sleeve wall and an outer sleeve wall, the component further having at least one migration blocking layer, the at least one migration blocking layer directly or indirectly covering the inner sleeve wall of the at least one sleeve.

Object

To provide an information processing system and the like which enables a user to start communication between a writing instrument and an electronic device with a simple operation.

Solution

An information processing system includes a writing instrument having a communication function and an electronic device that communicates with the writing instrument. The writing instrument includes a sensor that detects a motion, a determination unit that determines whether the motion detected by the sensor is a predetermined motion, and a transmission unit that transmits a predetermined signal to the electronic device. The transmission unit transmits, to the electronic device, the predetermined signal for causing the electronic device to execute a first operation without an operation by a user, when determining that the motion detected by the sensor is the predetermined motion.

Provided is a ballpoint pen refill including: an ink storage tube made of a synthetic resin and storing an ink thereinside; a ball holder made of a synthetic resin and attached to a distal end of the ink storage tube; a ball pressing rod mounted inside the ball holder; and a writing ball stored in a distal end of the ball holder and having a rear end side held by the ball pressing rod, in which the ball pressing rod includes: a fixing portion fixed to the ball holder; a movable portion slidable in a front-rear direction with respect to the ball holder; a compression portion connecting the fixing portion and the movable portion; and a rearward movement restricting portion protruding from a distal end of the fixing portion and provided with a gap from a rear end of the compression portion.

An artificial house plant, hereby named Pen Plant, made from artificial wired plants wherein each individual shoot comprises of a ballpoint pen arranged in a pot or vase to realistically resemble a house plant. Floral tape may be used to create the illusion of the extension of the plants shoot or root. Pieces of the plant may be used to decorate vase or pot with, in some cases and as shown below, a ribbon.
