Abstract:
The invention is related to a trowel that can be easily assembled and replaced for blade. The trowel comprises a handgrip shank and a knife holder that can accommodate a blade. The knife holder has a crossing locking groove inside and its top is firmly attached to the top of the supporting surface of the shank by fasteners. Thus, a suitable gap is formed between the bottom of the knife holder and the supporting surface. As a result, when the knife back has multiple locking hooks apart in equal distance, the blade can use knife back to slide in from the knife holder side and be locked inside the locking groove with the locking hooks. This provides a firm assembly positioning without downward detachment. In addition, the blade can be quickly removed from the knife holder side for replacement.
Abstract:
The invention is related to a scraping tool that can be assembled and replaced for scraper blade quickly. The scraping tool in general comprises a stick for hand grasp and a scraping section in the front. The invention mainly uses an arm of suitable length extended from the back end of a jaw clamp toward the middle. It uses fasteners to be located inside the groove in the back of the scraping section. The fastener is also used as pivot for the arm to swing back and forth. On the arm in the back of the jaw clamp, there is a control button that provides vertical pushing force in the back of the jaw clamp and allows strong clamping force in the front of the jaw clamp onto the scraper blade to achieve stable assembly and fast replacement for scraper blade.

The present invention provides a method for producing carbon nanotubes comprising (a) providing a substrate; (b) coating a catalyst layer on said substrate; (e) heating the substrate from step (b); (d) continuously supplying a carbon source to grow carbon nanotubes; (e) interrupting the supplement of the carbon source and supplying an oxidizing gas; and (f) resupplying the carbon source to make the carbon nanotubes obtained from step (d) to re-grow at a higher growth rate. The present invention also provides carbon nanotubes fabricated by the above-mentioned method. The carbon nanotubes have extremely excellent field emission properties.
Abstract:
A method for preventing gate to source/drain bridging and reducing junction leakage by preventing defects in the source/drain region in the fabrication of a silicided polysilicon gate is described. A polysilicon gate electrode on a semiconductor substrate and associated source and drain regions within the semiconductor substrate are provided wherein spacers are formed on the sidewalls of the gate electrode. A layer of titanium is deposited over the gate electrode, spacers and source and drain regions within the semiconductor substrate. Arsenic ions are implanted into the titanium layer. The semiconductor substrate is annealed for a first time whereby the titanium layer is transformed into a titanium silicide layer except where the titanium layer overlies the spacers. The titanium layer overlying the spacers is stripped to leave the titanium silicide layer only on the top surface of the gate electrode and on the top surface of the semiconductor substrate overlying the source and drain regions. The semiconductor substrate is annealed for a second time whereby the titanium silicide is transformed into a lower resistance phase. An insulating layer is deposited over the surface of the semiconductor substrate covering the gate electrode. Metallization with electrical connections is provided to complete the fabrication of the integrated circuit device.
Abstract:
The invention relates to a scraper structure, which is generally comprised of a long handle for handgrip and a scraping section in its front. Basically, the scraping section of the scraper is comprised of a jaw plate, a blade, a fastener and a fastening button. The front end of the scraping section extends downward or forward to form a blade slot and has a jaw base at the bottom to connect to the blade slot. The jaw plate has identical shape to the clamp jaw in the front of the jaw base. The fastener and the fastening button are combined to provide tightening and enable the clamp jaw in the front of the jaw plate to exert great pressure onto the blade and achieve quick blade replacement and assembly. Further, the fastening button can exert more force by the front hand in grasping the handle and achieve powerful scraping.

Abstract:
A single-arm two-electrode blood pressure measuring device and a measuring method thereof are provided. The single-arm two-electrode blood pressure measuring device includes two sensing electrodes, a photoplethysmogram (PPG) sensor, an analog signal processing unit, a filter and amplifier unit, an analog-to-digital conversion unit, and a digital signal processing unit. The single-arm two-electrode blood pressure measuring method includes: providing the two sensing electrode to sense an electrocardiography(ECG) signal of an user; providing the PPG sensor to sense a PPG signal; inverting a common mode signal between the two sensing electrodes and outputting to a filter of the analog signal processing unit by a differential amplifier; filtering and amplifying the ECG signal and the PPG signal by the filter and amplifier unit; and detecting multiple feature points of the ECG signal and the PPG signal to generate an estimated blood pressure value by the digital signal processing unit.
Abstract:
The invention relates to a scraper blade assembly structure. The scraper includes a stem for hand grip and a scraping section in the front. The scraping section includes a jaw plate, a blade and a fastening button. The jaw plate extends backward to form an arm. The jaw plate is attached to the inside of the jaw plate groove of the scraping section by a fastener that also serves as a lever pivot for swinging back and forth. When a fastening button goes into the inside of the jaw plate of the scraping section, it pushes the inner side of the arm of the jaw plate, and so as to generate a great holding power for the front of the jaw plate. Further, the fastening button can be a handle protruding from one side of the scraping section.
