Abstract: The method comprises steps of making a plaster dental cast of a patient, reconstructing jaw image assembly models, performing registration between physical stone and image model, adjusting the plaster dental cast based on a x-ray cephalometric plan, tracking movements of the plaster dental cast, obtaining optimal symmetry planes of the upper and lower jaw image assemblies, determining whether a degree of overall symmetry is elevated, and making surgical occlusal splints for surgical guiding. With foregoing method, possible results of executing an orthognathic surgical plan can be predicted and the surgical plan can be considered more carefully to achieve both occlusion function and facial symmetry.
Abstract: A method for producing microfine fibers having low resistance to deformation and high elasticity in accordance with the present invention comprises acts of: (a) providing polymer A and polymer B; (b) melting polymer A and polymer B to make a filament; (c) drawing the filament to make a staple fiber; (d) entangling the staple fiber to form a non-woven; (e) impregnating the non-woven with a impregnating agent; and may further have the acts of (f) impregnating the nonwoven with polyurethane; (g) coagulating the non-woven with dimethylformamide (DMF); (h) washing the non-woven with hot water; (i) impregnating the non-woven with a treatment agent; (j) abrading the non-woven to attain a split type mirofine fiber substrate; and (k) bonding a coating to the microfine fiber substrate. Therefore, the method can attain an artificial leather product having low resistance to deformation and high elasticity.
Abstract: The invention concerns the gyroscopic instrument engineering and can be used in determination of main navigation parameters for marine, air and surface vehicle positioning. Technical result consists in increased accuracy of output parameters, including substantial increase of the vehicle heading generation accuracy as well as principal improvement of dynamic properties of output parameter generation. To achieve these results control signals of gyro platforms or gyro platform models are generated under the condition that in the absence of ballistic deviations, autonomously, a natural period of the gyro platforms or the gyro platform models differ from Schuler period.

Abstract: A jet pump on pipe string and packer, pump body being provided with steplike pass channel embodied therein and communicates with pumped-out medium supplying channel and active medium supplying channel, connected to active nozzle at the output and to annular space. The pumped-out medium-supplying channel connects to the pipe string downstream of steplike channel via return valve. A hollow steplike cylindrical body sealing unit provided with a top part sealing element arranges in said steplike channel. An annular projection supported spring-loaded steplike piston is downstream. The piston lower position closes unit body holes. When the piston is in top position, the channel for supplying medium pumped-out from the well through the unit holes and pump bodies connects to the pipe string downstream of the pump body. The piston and sealing element include coaxial channels therein, used for passing a cable with logging instrument suspended below the pump body.
Abstract: A personal property securement device mountable to a vehicle may comprise a cable housing with a safety port that defines a passage extending from internal to external the housing. A cable may be threaded through the passage with one end fixed to a cable retention knob external the housing and the other end fixed to a reel that may be disposed for rotation within the housing. A power spring may present a torque on the reel to enable retrievable winding and tensioned unwinding of the cable. The property securement device may further comprise a ratchet mechanism in cooperation with the reel to release tensioning of the cable at given incremental extractions.
Abstract: A nozzle for the spraying of black liquor in a recovery boiler has discharge orifice inserts that can be removed and replaced with other inserts, to provide variable spray patterns, by changing the size and/or shape of the orifice of the nozzle, without requiring replacement of the entire nozzle body, to enable fine tuning of the atomization of the spray.

Abstract: An FM transmitter with improved degree of freedom in parts selection comprises: an oscillator connected with a crystal oscillator; a clock generating circuit uses a signal formed by frequency-dividing an oscillator output as a reference frequency, and which generates a clock having a frequency of an integer multiple of the frequency of the reference frequency; a DSP operates synchronously with the clock performing stereo modulation processing, FM modulation processing, and IQ modulation processing to inputted stereo data by digital processing; a frequency synthesizer generates a reference having a frequency an integer multiple of the frequency of the reference; mixers which mix signals outputted from the DSP with signals generated by the frequency synthesizer, respectively; an adder which adds outputs of the mixers; and an amplifier which amplifies an output signal of the adder and transmits the amplified signal from an antenna.
Abstract: An audio device capable of easily generating two or more sets of surround signals based on 2-channel stereo signals and a method for generating surround sound are provided. The audio device 100 includes: an SL signal generation section 20 and a BL signal generation section 40 as first surround signal generation units for receiving an L signal and an R signal as 2-channel stereo signals, extracting a component of the R signal having high correlation with the L signal, subtracting the component from the L signal, thereby generating a first surround signal; and an SR signal generation section 30 and a BR signal generation section 50 as second surround signal generation units for extracting a component of the L signal having high correlation with the R signal, subtracting the component from the R signal, thereby generating a second surround signal.
Abstract: A multilayered volume hologram structure of the invention comprises a substrate 2 for a certificate or the like, and an adhesive layer 5, a volume hologram layer 5 and a surface protective film 7 laminated on the substrate in the described order. When a multilayer structure consisting of the volume hologram layer 5 and surface protective layer 5 is forcibly released from the substrate for the purpose of making a photograph replacement or falsifying a personal information area, the volume hologram image can break down certainly, thereby ensuring prevention of falsification. A multilayered volume hologram structure-making label is useful for making a multilayered volume hologram structure.
Abstract: A laser rangefinder with a voice control function has a housing, a voice sensor module, a measure module, a circuit board and a display module. The housing has a voice-receiving hole and a screen. The voice sensor module receives voice commands through the voice-receiving hole. The measure module produces and emits a laser beam toward an object and then receives the laser beam reflected from the object. The circuit board judges the voice command sent by the voice sensor module to activate the measure module for calculating and determining a distance between the laser rangefinder and the object based by a time interval of the laser beam traveling toward and returning from the object. The display module shows a determined result on the screen.
Abstract: A smoothing circuit for realizing the miniaturization and the increase of integration scale of a circuit and for easily varying attack time and release time. This smoothing circuit comprises a capacitor, voltage comparator, charging circuit, and discharging circuit. The voltage comparator compares the terminal voltage of the capacitor with its input voltage and actuates the charging circuit or the discharging circuit according to a comparison result. The charging circuit charges the capacitor by intermittently supplying charging current. The discharging circuit discharges the capacitor by allowing discharging current to flow intermittently.
