Inventor: SIM CHANG SEOP
IPC: D03D15/00
Filed: 1998-09-22
Abstract: PURPOSE: A production method is provided to improve the surface effect of a suede fabric by uniformly embodying a napping of very fine fineness in the surface of fabric when a nap is raised. CONSTITUTION: A suede fabric is used in a cotton yarn of sea island typed polyester single fiber in a weft and a false twisted yarn of polyester long fiber in a warp. The cotton yarn of sea island typed polyester single fiber is the cotton yarn to become the 10-40 thickness by spinning the polyester single fiber of the 0.01-0.1deniers fineness of single fiber after decreasing. A woven fabric is thermally set after passing a re-reduction using a relaxer scouring and a non-tension dyeing device. The fiber becomes very fine by the decreasing process, and the surface effect of the fabric such as a soft touch is embodied thereby. The fabric is dyed after embodying the very fine fiber in the surface by napping.

Filed: 1998-09-24
Abstract: PURPOSE: A method for isolating a trench having a nitride liner of thin film is provided to prevent the generation of a dent on an interface between an active region of a semiconductor substrate and a field region where an isolation is formed. CONSTITUTION: A method for isolating a trench having a nitride liner of thin film is provided to form a trench(135) on a field region on a semiconductor substrate(110) and then to form an isolation by filling an insulation material in the trench. A silicon nitride pattern(120) is formed on the field region on the semiconductor substrate. A spacer(130) is formed on a side wall of the silicon nitride pattern. The trench is formed by etching the revealed semiconductor substrate using the spacer as an etching mask. The spacer is removed. Thus, the side wall of the silicon nitride pattern is connected to a side wall(140) of the trench. A nitride liner is deposited on the front of the structure. Then, the isolation is formed by filling the insulation material. A material layer on top of the semiconductor substrate of the active region is removed. The etching of the nitride liner below the top surface of the semiconductor substrate is prevented because the nitride liner wraps the side wall of the silicon nitride pattern and the side wall of the trench.

Title: Opto-acoustic thrombolysis
Inventor: CELLIERS PETER
IPC: A61B19/00
Filed: 1997-04-23
Abstract: PURPOSE: A device is provided to analyze an artery thrombus by using a high frequency wave of series of low energy laser pulse generating a supersonic wave excitation to a fluid being near to the thrombus. CONSTITUTION: This invention is a catheter-based device for generating an ultrasound excitation in biological tissue. Pulsed laser light is guided through an optical fiber (10) to provide the energy for producing the acoustic vibrations. The optical energy is deposited in a water-based absorbing fluid, e.g. saline, thrombolytic agent, blood or thrombus, and generates an acoustic impulse in the fluid through thermo elastic and/or thermodynamic mechanisms. By pulsing the laser at a repetition rate (which may vary from 10 Hz to 100 kHz)an ultrasonic radiation field can be established locally in the medium. This method of producing ultrasonic vibrations can be used in vivo for the treatment of stroke-related conditions in humans, particularly for dissolving thrombus or treating vaspasm. The catheter (14) can also incorporate thrombolytic drug treatments as an adjunct therapy and it can be operated in conjunction with ultrasonic detection equipment for imaging and feedback control and with optical sensors for characterization of thrombus type and consistency.

Title: Device and method for radio transmitters
Inventor: CARLSSON TORSTEN JOHN
IPC: H03G3/30
Filed: 1997-06-04
Abstract: PURPOSE: A device for radio transmitters is provided to solve the difficulties in reducing the power consumption, non-linearity in the output signal when using non-linear amplifiers in radio transmitters, and achieving a high signal-to-noise ratio in the output signal without connecting filter arrangements after such an amplifier. CONSTITUTION: The transmitter stage in the radio transmitter comprises a converting device(5) PCH, an amplifier control device(8) PAC, a power detector(13) and a power amplifier(2). An information signal has been split into two components before the transmitter stage; a phase reference component signal and an amplitude component signal. The phase reference component signal is connected to the converting device, which generates a pure phase modulated signal of constant amplitude and with the appropriate carrier frequency to the amplifier, which amplifies and outputs the signal as an aerial signal to an aerial with associated circuitry. This signal is fed back to the converting device so as to phase lock the aerial signal to the phase reference component signal. The output power from the amplifier and the amplitude of the aerial signal are controlled by the amplitude component signal and a control value signal for the output power. A power detector senses the current consumption of the amplifier and outputs a true value signal to the control device of the amplifier. The true value signal is a measure of the output power, as there is a specific correlation between the output power and the current consumption.
