Title: Method of determining transmission coefficient of ac calibrator
Inventor: EDOUIN EI SUROON
IPC: G01R27/28
Filed: 1988-05-30
Abstract: PURPOSE: To exactly decide the frequency transmission characteristics of a linear or almost linear signal processing system for an arbitrary input waveform by calculating the vector sum of input patterns, calculating frequency area conversion, and calculating a correction coefficient vector. CONSTITUTION: A data acquiring system(DAS) 10 incorporates a device necessitating calibration, and the response of the DAS 10 is calibrated for the frequency transmission function H(ω). Patterns are inputted one by one each time from a Walsh pattern generator to the DAS 10, and each response yk (t) and a value ak , for weighting are stored in a memory. Then, the Fourier transformation of the added responses of the DAS 10 is calculated. The sum of the Fourier transformation of the input patterns calibrates one part of a rate used for deciding the frequency transmission function. Therefore, the rate of the Fourier transformation of the sum of the response signals to the Fourier transformation of the sum of the input signals to the DAS 10 is calculated so that the frequency transmission function H(ω) can be obtained.

IPC: G06K17/00
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To enhance the reliability of such devices as a personal computer, facsimile, printer, etc., where the cards are loaded, by using a static charge removing member to eliminate the static electricity of the card before the card inserted through its slot reaches a terminal connecting position. SOLUTION: A static charge removing unit 1 is placed at a memory card slot of a card guide member 2 and holds a static charge removing member 1a at a prescribed position. The member 1a consists of a brush and a cloth for removing state charge or a plate spring, etc. Then, the unit 1 is attached to a side plate made of a conductive metallic member by means of a conductive fixing screw 3 together with the plastic member 2. When a memory card is inserted, the static electricity charged on the card flows to the side plate and eliminated via the unit 1 before the card gets close to a terminal connector.

Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To provide the orthogonal frequency division multiplexing(OFDM) receiver by which noise included in a correlation detection output is eliminated in an excellent way through a simple configuration. SOLUTION: The received OFDM signal is converted into a base band OFDM signal at a frequency conversion circuit 1, a harmonic component is eliminated at an LPF 2, given to an A/D converter circuit 3, where the signal is converted into a digital signal and it is fed to a fast Fourier transform(FFT) circuit 4. On the other hand, the digital signal from the A/D converter circuit 3 is fed to a correlation detection circuit 6 directly and via a one-symbol delay circuit 5, and synchronization is detected by using the correlation for the guard interval period of OFDM.  The detected synchronization detection signal is given to a noise elimination circuit 9, where a high level noise component is eliminated from the signal, a waveform processing circuit 7 generates a synchronizing signal from the synchronization detection signal from which the noise component is eliminated and the synchronizing signal is fed to the FFT 4. The FFT 4 applies FFT to the digital signal from the A/D converter 3 based on the synchronizing signal to demodulate the OFDM modulation wave.

IPC: B60R22/34
Filed: 1993-06-02
Abstract: PURPOSE:To provide structure of mount a retractor device with a pretensioner mechanism capable of reducing the longitudinal width of a center pillar. CONSTITUTION:Since a cylinder 24 is tilted to the side of the longitudinal center line S of a retractor body 9, and the front edge or rear edge of a center pillar 26 and the cylinder 24 become hard to interfere with each other, a front edge 27a or rear edge on the side corresponding to the cylinder 24 of the center pillar 26 can be positioned near the longitudinal center line S, and the longitudinal width P2 of the center pillar 26 can be reduced. Since a guide cylinder 25 formed bent downward for insertion of wires is provided in the lower end part of the cylinder 24, a wire 18 can be smoothly pulled up even when the cylinder 24 is tilted. Therefore, the performance of a pretensioner mechanism itself is surely maintained.

Title: Power measurment mechanism of optical fiber for laser power transmission
Inventor: DOI YUZURU
IPC: G01J1/42
Filed: 1980-09-24
Abstract: PURPOSE:To make it possible to accurately measure the laser power at the emitting end of a laser power transmitting optical fiber, by measuring the laser beam part reflected from the emitting end of the fiber by means of a sensing means disposed in the vicinity of an incidence end of the fiber. CONSTITUTION:A laser beam source 1 produces a laser beam 2 which is introduced through a focussing lens 3 into the incidence end 4a of a transmitting fiber 4 and is transmitted through the latter so as to be emitted from the emitting end 4b of the same. A part of the laser beam is inevitably reflected at the emitting end 4b and runs in the reverse direction through the fiber 4 so as to be emitted from the incidence end 4a as a beam 6. This beam 6 is made to pass through the lens 3 and is reflected by a perforated mirror 7 (or a half mirror) which is disposed so as not to intercept the incidence laser beam 2. The reflected beam is then transmitted to a display unit 11 for a display thereof, through a photosensor 8, amplifier circuit 9 and an arithmetic operation circuit 10. It is possible to use a perforated sensor 13. According to this arrangement, it is possible to countinuously and precisely measure the laser power while maintaining continuous application of the laser beam. The apparatus, therefore, can suitably be used in medical treatment.

Abstract: PURPOSE:To prevent generation of errors with a simple structure by providing a number of dot-like projections on the inner surface of another case placed oppositely to a lifter and arranging the dot-like projections in the radial direction without leaving no clearance with the lifter. CONSTITUTION:A plurality of roughly columnar projections having diameters of 0.5 to 1.0mm and heights of 0.1 to 0.5mm are arranged disorderly on the inner surface of an upper case 20 placed oppositely to a lifter 31 in the radial direction.
