Title: Magnetic resonance imaging method and apparatus
Inventor: MEULEN PETER VAN DER
IPC: G01R33/565
Filed: 1993-06-28
Abstract: PURPOSE: To provide a magnetic resonance imaging method and device to reduce effect of eddy current and interference such as phase distortion of RF pulses without using an auxiliary coil or the like. CONSTITUTION: In MRI equipment a gradient magnetic field to be switched is applied in the forms of slice selection (231-234), phase coding (241-243, 241'-242') and readout gradient (252-253). These switches of the gradient magnetic field generate eddy current in the metal part of this device. The eddy current interferes with the magnetic field applied, thereby changes the phase of the precessing spin of a subject, causing defects of reproduced images. Another interference is phase distortion of an RF amplifier. It is possible to greatly compensate these interferences by changing the gradient (251, 231') between the excited pulse (221) and the first refocused RF pulse (222) and/or changing the phase of the RF pulse. The size of the gradient is adjusted by measuring the time position and the relative phase of the spin/echo signals (162, 163) in the preparatory sequence (121-173).

Title: Limiter circuit
Inventor: TAJIMI NOBURO
IPC: H03G11/00
Filed: 1988-07-27
Abstract: PURPOSE:To obtain excellent accuracy, frequency characteristic and distortion characteristic by adopting a feedback type utilizing a differential amplifier for a limiter circuit and employing a transistor(TR) to constitute its feedback circuit. CONSTITUTION:The feedback type limiter circuit consists of a differential amplifier 1 and a feedback TR 3 for limiter. Then the TR 3 for limiter is completely turned off in the region where no limiter is applied. Thus, the original signal is not distorted and the deterioration in the frequency characteristic is not caused. Since the difference from a setting voltage is compressed to a fraction of loop gain of the feedback circuit in the limiter region, it is possible to apply limiting up to a high frequency when a high gain is applied to the feedback circuit at a broad band. Thus, the limiter circuit with excellent accuracy, distortion characteristic and frequency characteristic is obtained as a simple circuit against a signal with a small amplitude and a wide band such as a picture signal.

Filed: 1980-12-26
Abstract: PURPOSE:To detect the position of a travelling object without regulating the moving range of the travelling object, by obtaining the correlative function between plural distance function signals stored in a storage device and the distance function signal sent from a contour detector and then having the discrimination for the degree of coincidence between both signals. CONSTITUTION:A contour detector 3 mounted on an unmanned car 1 which travels within a certain space measures a distance (d) between the car 1 and an obstacle X. This distance signal and an angle signal of each time are written into a memory of an electronic computer 8 in the form of the distance function signals. At the same time, the devices within the space which can be viewed at the front from the car 1 and the profile of the wall surface are previously  stored in the memory as plural distance function signals. These signals are compared with the distance function signals supplied from the detector 3. Thus the  position and direction signals of the car 1 are outputted based on the conditions  by which the distance function signal to which a coincidence is obtained.

Filed: 1988-07-25
Abstract: PURPOSE:To suppress a force for opening a metal mold, and to reduce the impregnation of resin by providing a through hole at the cull bottom of a runner block, inserting a pin into the hole, and supporting the pin from below by the use of a post. CONSTITUTION:A through hole 3c is formed at the bottom of the cull 3a of a runner block 3, a pin 15 is inserted into the hole 3c, and supported from below by posts 16 in such a manner that the load received by the section of the pin 15 is not applied to a component except the posts 16 for supporting the pin 15. Accordingly the pin 15 contracts the posts 16 by the resin pouring pressure to slide the hole 3a toward the pouring direction. In this case, a lower surface plate 10 is not necessary to support a part corresponding to the area of the pin 15 against the pouring pressure of the cull 3a. Thus, a force for opening a metal mold is reduced, and the impregnation of the resin at the parting faces of the molds can be decreased.
