Title: Quadrature modulator
Inventor: TANAKA YASUHIDE
IPC: H03C3/40
Filed: 1994-03-29
Granted: 1997-06-10
Abstract: A quadrature modulator multiplies two carriers which are 90° out of phase with each other by a sine com-ponent and a cosine component of a baseband signal, respectively, adds the product signals to each other, and amplifies the sum signal to produce a quadrature-modulated output signal.  The quadrature modulator includes a phase comparator for detecting a phase distortion suffered when the sum signal is amplified, a first phase controller for correcting the phase of a single carrier generated by a carrier oscillator based on a compared phase output signal from the phase comparator, a phase difference detector for detecting the difference between 90° and the phase difference between the two carriers, and a second phase controller for outputting the two carriers to be multiplied by the sine and cosine components of the baseband signal and controlling the phase difference between the two carriers generated from the single carrier whose phase distortion has been corrected by the first phase controller, into 90° based on a detected output signal from the phase difference detector.

Abstract: A package structure, in which a drug-containing pressure-sensitive adhesive sheet comprising a support, a drug-containing pressure-sensitive adhesive layer, and a separator in this order is packaged and sealed in a packaging material, is disclosed, wherein unevenness is provided on at least one of the surface of the support on the side in contact with the inside of the packaging material, the surface of the separator on the side in contact with the inside of the packaging material, and the inside surface of the packaging material.      The unevenness reduces the contact area between the packaging material and the sheet so that an adhesive, a plasticizer or any liquid component of the adhesive layer is prevented from adhering to the inside of the packaging material. Therefore, the sheet can easily be taken out of unit package on use.

Abstract: Ultra-short  transform-limited  optical  pulses,  to  be utilized  for  high  bit-rate  transmission  systems,  are obtained through direct modulation of a semiconductor laser by means of pulses of such a duration as to excite only the first peak of the relaxation oscillations of the cavity of laser, tuned to such a length that the pulse portions that overlap inside the cavity interfere constructively.   The pulses emitted by the laser are then made to pass in a fibre with high negative dispersion to compensate for the phase effect due to the chirp.

Abstract: A system and method provide a low distortion hydrophone. A first known piezoelectric element is mounted so as to receive a pressure signal. A second piezoelectric element is provided with a means of receiving and enhancing the same pressure signal. Since a piezoelectric element is a capacitor, another capacitor is coupled in parallel with the second element to serve as a divider. The output voltage of the combination of the two elements is taken as the difference between the positive terminals of the two elements. Thus, the effect of the pressure enhancer and capacitance divider is to provide a difference in potential between the fundamentals from the two elements, while rendering the amplitude of the second harmonics equal. The two equal second harmonics cancel each other out at the output terminals, while retaining a useful fundamental for further signal processing. Further, the means of enhancing the pressure signal may comprise a cone-shaped baffle to amplify the pressure signal, or it may comprise a thinner diaphragm upon which the piezoelectric element is mounted to increase the flexing and thus the stress on the element. Also, more than two hydrophone elements may be coupled together to even more closely eliminate distortion over a wide pressure range.

Abstract: A lightweight exercise device offers variable resistance, including assisted resistance, for strengthening and conditioning various parts of the body. The device may be strapped to the user's back and is provided with rollers for contact with a wall, door, pad, or floor. The rollers are mounted on rotatable axles on the rear face of the device and operate in conjunction with a tensioning system which uses durable elastic cords or bands. As the rollers are rotated in one direction, the cords or bands wind about the axles thereby progressively increasing the cord or band tension. This increased tension thereby increases the resistance to rotation of the axles and the rollers mounted thereon. As the rollers are rotated back, the cords or bands unwind and the roller resistance decreases. The cords or bands may be wound by rolling the rollers or, in one embodiment, by turning a tension preadjustment crank connected to an intermediate axle. In one embodiment of the invention, the cords are connected to cams maintained on the axles. The cords or bands are easily connected to the axles so that the range of resistance provided by the device may be changed simply by changing the size and flexibility of one or more cords or bands. The device is of particular use in performing exercises for the legs, shoulders, and abdomen.
