20090209686 | Eraser - Provided is a plastic eraser excellent in safety and environmental pollution resistance and, not detracting from the erasability thereof, further excellent in bleeding resistance and eraser dust gatherability. The eraser comprises a base resin such as a vinyl chloride resin and, as incorporated therein as a plasticizer, a liquid acrylic polymer having a glass transition point (Tg) of not higher than 0° C. The eraser may comprise the liquid acrylic polymer alone or as combined with one or more other plasticizers. Containing the liquid acrylic polymer as a plasticizer, the eraser has excellent bleeding resistance and excellent dust gatherability which could hardly be balanced. | 08-20-2009 |
20090060625 | Pressurized pen - Provided is a pressurized pen, which is enabled to enhance the sealing property of a compression chamber at a pressurizing time in the knocking operation of a knock mechanism and to improve the durability. A pressuring pump mechanism includes: a pressure member having a front end opening portion communicating with the inside of a medium containing tube and a compression chamber made extensible and contractible in axial direction; and a push member for coming in axial direction into and out of abutment against a rear end opening portion of the pressure member and for pushing the compression chamber of the pressure member in a gas-tight condition in a compressing direction. The push member is associated with the pushing action of a knock mechanism such that it is enabled to irrotationally move toward the rear end opening portion of the pressure member. | 03-05-2009 |
20080277517 | Coating film transfer tool - A coating film transfer tool is provided capable of firmly preventing a non-transcribing portion from being brought about at a transcribed face by coating film detachment of the transcribing tape at an application head and eliminating idle slip at every time of starting to be used. The coating film transfer tool has a protecting cover which is slidable in a front and rear direction between an advanced position in a state of covering the application head and a rear position in a state of exposing the application head at a front end portion of a case main body. The protecting cover is urged in a direction of the advanced position by a spring. There is further provided a tape reel out means for reeling out the transcribing tape to the application head at inside of the case main body. The tape reel out means is moved in cooperation with driving means for moving the protecting cover to the rear position when operating the driving means in starting to be used. | 11-13-2008 |
