摘要:
A ball-point pen having a coupling, a tip at the distal end of the coupling, and a reservoir tube at the proximal end of the coupling. The tip may held in a tip holder, which, in turn, is coupled to the distal end of the coupling. A valve chamber is formed within the coupling with a ball seat having a guide hole therethrough on the rear portion of the valve chamber and projecting ridges on the front portion of the valve chamber. When the ball-point pen is positioned with its tip upward, a ball valve is brought into contact with the ball seat to close the guide hole and thereby prevent back flow of ink. When the ball-point pen is positioned with its tip downward, the guide hole is opened and the ball valve contacts the rear ends of the projecting ridges, so that ink flows into the tip through the guide hole, the valve chamber, and grooves formed between the ridges. A spring may be interposed in the inner hole of the tip with its proximal end held in place by the coupling. The distal end of the spring presses a writing point ball into contact with the ball-holding portion of the tip. A low-viscosity ink or an ink having shear thinning properties, i.e., statically a high viscosity which is decreased upon rotation of the ball during writing, is preferably used.

A writing implement includes a cylindrical shaft member, a pen tip member which is fixed to one end of the shaft member and from which colored ink seeps out, liquid for ink which is stored in the shaft member and which comprises a part of the colored ink seeping out from the end of the pen tip member, and colorant to be added to the above described liquid for ink to be the colored ink. Moreover, at least a part of a cylindrical side surface of the shaft member corresponding to the storing part of the liquid for ink is formed to be transparent. Between the liquid for ink and the colorant-storing part storing the colorant is provided a colorant-adsorbing core which introduces the liquid for ink into the colorant-storing part while capturing the colorant diffusing toward the storing part of the liquid for ink.

摘要:
A charging system and method is capable of starting or stopping charging a battery of a vehicle at a convenient time. A portable device and a vehicle unit can communicate with each other. A user is determined to be away from the vehicle based on a result of communication between the portable device and the vehicle unit. A charging ECU starts charging a battery when the user is away from the vehicle. Charging of the battery can be started when the user is assumed to have stopped using the vehicle and will not use the vehicle for a period of time. When the user is determined to be close to the vehicle it is assumed that use of the vehicle will be resumed at which point the system instructs the charging of the battery to be stopped. The system thereby allows the vehicle to be ready for use.
摘要:
There are provided an inorganic compound-containing thermoplastic resin composition that practically retains various properties of a general-purpose resin such as mechanical properties and moldability and has excellent thermal conductivity, and a highly thermally conductive molded article molded using the resin composition.In a polymer alloy comprising a thermoplastic resin excluding a thermoplastic polyester resin, a thermoplastic polyester resin and a highly thermally conductive inorganic compound, the thermoplastic polyester resin forms a continuous phase and the highly thermally conductive inorganic compound is preferentially present in a phase other than the thermoplastic resin excluding a thermoplastic polyester resin. Therefore, the composition and the highly thermally conductive molded article molded using the resin composition can have a thermal conductivity improved only by adding a relatively small amount of the highly thermally conductive inorganic compound.
