Title: Inclined magnetic field coil for mri apparatus
Inventor: YOKOI MOTOHISA
IPC: G01R33/38
Filed: 1990-04-17
Abstract: PURPOSE:To generate a designated inclined magnetic field by modulated pulse drive by providing a filter plate adapted to check a modulated pulse from passing and pass an inclined magnetic field pulse on the inside of a resin field for sealing a coil conductor. CONSTITUTION:An inclined magnetic field coil 20 is formed cylindrically by sealing a coil conductor 21 by a resin member 22, and an grounded filter plate 23 made of copper 5-10mum thick is disposed on the inside of the resin member 22. The filter plate 23 is constructed so that a joint 23a is formed in a position inclined at 45 from the direction X in such a manner as to generate symmetrical inclined magnetic field pulses both in the directions X, Y of inclined magnetic field. In this arrangement, when a power supply of a modulated pulse is given from a PWM power supply 30 to the coil 20, even if switching noise Ns goes on an electric current flowing through the coil conductor 21, the noise is reduced by the filter plate 23. The filter plate 23 prevents the occurrence of coupling of an excitation pulse and an inclined magnetic field pulse as well, so that even if the excitation pulse Pr is generated with the generation of an inclined magnetic pulse, low-frequency noise Nr will not go thereon so as to form a designated inclined magnetic field pulse Pt.

Title: Light signal processing element
Inventor: YOKOO YASUHIKO
IPC: G02F1/13
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To provide a light signal processing element under the application of a simple constitution and a simple manufacturing method, using a plurality of types of wavelength, by stacking a film having a nonlinear optical effect and cholestric liquid crystal layers capable of showing different optical rotatory dispersion characteristics, so as to make a plurality of beams of different wavelength incident from the cholestric liquid crystal layers. SOLUTION: A first layer 11 and a second layer 12 are cholestric crystals showing different spiral pitches, made of polymer doped with a tertiary nonlinear optical substance through a film of tertiary nonlinear optical material, and clamped with glass substrate 13 and 14. When input light 18 composed of each control light and reference light superposed is incident from the cholestric liquid crystal layers, the plane of polarization of each control light comes to be incident on a tertiary optical material in such a state as inclined by 45 degree for the plane of polarization of the reference light. As a result, when only one control light exists, the reference light changes in the plane of polarization and passes through a polarization plate 17, but in the presence of both control lights, polarization changes offset each other, thereby preventing the reference light from passing through the polarization plate 17.

Title: Direction finder
Inventor: EGARASHI KEIICHI
IPC: G01S7/40
Filed: 1980-07-25
Abstract: PURPOSE:To enable the accurate direction finding to be readily performed by detecting the variation period of the receiving radiowave which varies periodically, and measuring the direction of the arriving radiowave in synchronization with said period. CONSTITUTION:A receiving antenna 5 which is driven by a rotating device 4 is connected to a receiver 3. The output of the receiver 3 is connected to a measuring device 6 and a synchronous detector 7. When a transmitting antenna 2 is stationary, the receiving electric field is steady and the direction can be readily found. However, when the antenna 2 begins to rotate, the field intensity periodically varies as shown in the Figure. The synchronous detector 7 stops the direction finding operation of the measuring device 6 by a DC voltage b, and detects a period S, time t when the maximum signal E appears during said period, and a time length W of E. Then, the synchronous detector 7 offsets the DC voltage b, controls the measuring device 6 via a synchronization control device 8, and makes the receiving device 6 perform the direction measurement at the time t for the time length W, repeatedly. In this way, erroneous measurement due to side lobe is avoided, and the accurate direction measurement can be performed.
