Abstract: An impact dissipation tool for supporting a downhole tool in downhole applications. The tool includes a base and a housing. The tool also includes a carriage located within the housing and coupled to the base, the carriage being movable relative to the housing upon a predetermined impact force. A dissipator disposed inside the housing is collapsible due to the relative movement of the carriage and the housing. The collapse of the dissipator dissipates the impact force transferred to the downhole tool.

Abstract: Various embodiments illustrated and described herein include at least one of systems, methods, and software for invoice gap number alerting and processing. Some such embodiments include monitoring, within a computing system involved in at least one of invoice generation and storing, continuity of invoice numbering. Upon noting a missing invoice number, some embodiments include stopping creation of invoices and pushing an alert to a managing entity responsive to noting the missing invoice number. Input will typically be received from the managing entity regarding a missing invoice number. In response to the received input, various embodiments further facilitate registration of the missing invoice number to enable creation of the new invoice and restart creation of invoices.

Abstract: Embodiments of the present invention generally relate to methods and systems for logging through a drillstring. In one embodiment, a method of logging an exposed formation includes drilling a wellbore by rotating a cutting tool disposed on an end of a drillstring and injecting drilling fluid through the drillstring; deploying a BHA through the drillstring, the BHA including a logging tool; forming a bore through the cutting tool; inserting the logging tool through the bore; longitudinally connecting the BHA to the drillstring; and logging the exposed formation using the logging tool while tripping the drillstring into or from the wellbore.

Abstract: Disclosed are systems and methods that permit both real-time, and off-line, measurement of weld penetration depth. Exemplary systems and methods comprise an ultrasound source, such as a pulsed Nd:Yag laser, that simultaneously generates longitudinal and shear waves that radiate adjacent one side of a weld joining two specimens. An ultrasonic sensor, such as an electro-magnetic acoustic transducer or a piezo-electric transducer, capable of detecting shear and/or longitudinal waves, is disposed on an opposite side of the weld from the source. A signal processor is coupled to the sensor that processes time of flight signals for selected longitudinal or shear waves transmitted across the weld seam. The signal processor implements an algorithm that computes the weld penetration depth from the time of flight signals.

Abstract: Since the capacitor of the semiconductor memory has the storage electrode comprising a shape of the cylindrical structure having rough polysilicon portions on base and sidewall portions thereof, it can increase electrostatic capacitance. Further, since the rough portions of the base and sidewall rough storage electrode layers are respectively formed by independently controlling a condition of Chemical Vapor Deposition, it can easily control formations of the rugged portions of the capacitor, therefore it can achieve the improvement of the productivity of the rough portions. Accordingly, the semiconductor can achieve a stability of a memory operation.

Abstract: A method of manufacturing a one-transistor one-capacitor memory cell structure. In a first step, a buried insulating film layer is formed in a semiconductor substrate and a semiconductor layer is formed on the buried insulating film layer. In a second step, a capacitor trench is formed in the substrate by penetrating through the buried layer and a dielectric film layer is formed on an inner side wall surface of the trench. Then, a conductive material is filled into the trench to form a capacitor. Finally, an MIS transistor is formed in the semiconductor layer adjacent to the trench capacitor such that either the drain or the source makes contact with the conductive material.

In a first step, a buried insulating film layer is formed in a semiconductor substrate and a semiconductor thin film layer is formed on the buried insulating film layer.

Then, a conductive material is filled into the trench to form a capacitor. Finally, a MIS transistor is formed in the semiconductor thin film layer adjacent to the trench capacitor such that either the drain or the source makes contact with the conductive material.

Abstract: An LDD MIS FET comprises a silicide over the lightly doped regions to reduce the parasitic resistance and to prevent the depletion of the lightly-doped regions, reducing the hot carrier injection effect. By the provision of the silicide, the overall parasitic resistance can be made low. Moreover, the increase in the resistance of the lightly-doped region due to the negative charge being trapped at the interface of or in the oxide film over the lightly-doped region and the resultant degradation in the characteristic are eliminated.
