Abstract: A writing tool includes a writing unit, a capillary member, a dispensing unit, and a replaceable ink cartridge. The capillary member, the dispensing unit, and the replaceable ink cartridge are mounted in the writing unit. The dispensing unit contacts the capillary member and has at least one cutting portion. The replaceable ink cartridge accommodates ink therein and has a film at one end thereof. The replaceable ink cartridge can be installed in the dispensing unit and the film can be pierced and cut by the at least one cutting portion. The ink flows through the film and is delivered to the writing unit via the capillary member and the dispensing unit for writing. The writing tool can thus dispense the ink fluently and leave no residual ink.

Abstract: Example implementations relate to establishing communication links with computing devices. As an example, a device stand includes a first member including an attachment feature to couple the device stand to a computing device. The device stand also includes a second member including a rotation track to enable the first member to rotate with respect to the second member to decouple the device stand from the device. The device stand further includes a third member including an opening to receive the attachment feature. The second member is situated between the first member and the third member. The device stand further includes a first sidewall having a first slope and a second sidewall having a second slope that is different from the first slope. The first sidewall and the second sidewall are defined by the first member and the second member.

Abstract: A writing tool has a pen tube, a capillary unit, and a dispensing unit. The capillary unit is mounted in the pen tube, and is connected to a nib. The dispensing unit is mounted in the pen tube, and has a communicating tube and a pressing segment connected to the communicating tube. The pressing segment has at least one connecting arm connected to the communicating tube. A dispensing interval is formed between the communicating tube and a periphery of the pressing segment. The communicating tube contacts the capillary unit to make the capillary unit form different compression densities via the pressing segment and the dispensing interval, thus facilitating dispensing ink downward easily through the dispensing interval and providing a better occlusion effect to further avoid ink leakage.

Abstract: A pressure regulating device for a writing tool has a deformable member. Minor air pressure variations in a pen tube of the writing tool can be regulated by deformation of the deformable member. Major air pressure variations in the pen tube can also be regulated by movement of the pressure regulating device. Thus, the pen tube of the writing tool can avoid internal air pressure imbalance caused by external high temperature or low air pressure. Before the writing tool is shipped from a manufacturer, the deformable member is pressurized in advance, such that the minor air pressure variation formed when a pen cap caps the writing tool offsets the air pressure pre-applied to the deformable member. Accordingly, ink inside an internal chamber does not spout out upon removal of the pen cap and the ink will not be overly dispensed or leak during writing.

Abstract: A reciprocating pencil sharpener has a shavings receptacle, a stationary member, a cutter and a ratchet mechanism. The cutter includes a blade secured to a blade holder. The ratchet mechanism is mounted between the stationary member and the cutter and allows the cutter to rotate relative to the stationary member in one direction only. When a user desires to sharpen a pencil, the user can keep the pencil in the hand and rotate the pencil in reciprocating rotation, thus obtaining the sharpened point of the pencil. Consequently, it is convenient for the user to apply a rotational force and a high efficiency of sharpening operation is achieved.

Abstract: The present invention discloses a method for non-fluorescence higher harmonic generation ground state depletion super-resolution microscopy, it includes the following steps: providing an organic material unit, focusing excitation light and ground state depletion light, generating a higher harmonic signal, performing ground state depletion and performing microscopic imaging. With the implementation of the present invention, the stimulated electrons of the organic material remains majorly on the singlet (S1) state or the triplet (T1) state, instead of the ground (S0) state, to provide modulation of the spatial distribution of the non-fluorescence signal, and make STED microscopy applicable to non-fluorescence signals to promote the resolution of the images.

Abstract: This invention relates to a vacuum-pump sucker for high-resolution microscopy comprising a sucker body and a transparent plate. The vacuum-pump sucker is designed as a stabilizer for sample stabilization in a clinical optical virtual biopsy system with sub-micron resolution. The sucker is connected with a vacuum pump. As the vacuum pump pumps out air or gas, tissues around the imaged area will be sucked by the sucker and the distance between objective lens and the imaged tissue can be stabilized. In this way, the stability and resolution of the clinical biopsy system can be greatly improved.

Abstract: An automatic cover-opening device has a body, at least one cover panel and a recoil mechanism. The body has an insertion hole defined in the body. The at least one cover panel is mounted on the body and moveably closes the insertion hole. Each one of the at least one cover panel has a guiding segment having at least one guiding edge inclined relative to an axis of the insertion hole to guide an axial force along the axis of the insertion hole to a lateral direction non-parallel with the axis, so as to generate a lateral component force for opening the at least one cover panel. The recoil mechanism is disposed on the body to push the at least one cover panel to a closed position for closing the insertion hole. With such an arrangement, an automatic cover-opening device that can be applied for insertion of a rod-like object is provided.
