Title: Method for removing out-of-plane dust of mri sequence
Inventor: SUGIURA ATSUO
IPC: G01R33/28
Filed: 1989-03-10
Abstract: PURPOSE:To eliminate the adverse effect of out-of plane dust by expelling a dust echo to the outside of a lead gradient by applying a gradient magnetic field of a reverse phase having an area equal to or slightly larger than the area of the lead gradient between a 180 deg. pulse an the lead gradient. CONSTITUTION:For the purpose of expelling a dust echo 12 to the outside of a lead gradient 8 in order to eliminate out-of plane dust, the area of an FC gradient C33 is taken so as to become almost equal to that of the lead gradient to calculate the amplitude G3 of the FC gradient C33. Based on the gradient moment nullifying method, the phase of a spin at the central position of an SE signal is adjusted so as to become zero to erase the effect of blood flow to respectively calculate the amplitudes G1, G2, G3 of FC gradients A31, B32, C33. The FC gradient A31 thus obtained is applied between a 90 deg. pulse 1 and a 180 pulse 7, and the FC gradient B32 is applied immediately after the FC gradient A31 and before the 180 deg. pulse 7 and the FC gradient C33 is applied after the 180 deg. pulse 7.

Title: Optical associative memory
Inventor: YOSHINAGA HISAO
IPC: G11C15/00
Filed: 1988-03-14
Abstract: PURPOSE:To improve an S/N by detecting the most intensive one of correlative light separated in terms of space, radiating the hologram of reference light corresponding to an image having the highest correlation with the input to a reference light source based on information on the detecting position of said most intensive light, and obtaining the image having the highest correlation as an output. CONSTITUTION:When the information is recorded in a hologram 23, the incident angle of the reference light 33 is changed for each information to be recorded. Thus input information light 32 is radiated on the hologram 23 where plural pieces of information are recorded. Then the correlation is secured between the information recorded in the hologram 23 and the input information 21. Then the information having the highest correlation with the information 21 is identified based on the intensity of scattered light having the optical intensity proportional to the correlative value scattered from the hologram 23. Based on the identified information, the light used as the reference light 33 is selected and radiated on the hologram 23. Thus the information reproduced out of the hologram 23 is taken out as the output which is most similar to the information 21. In such a way, the S/N is improved.

Title: Method for measuring partial discharge of cable
Inventor: EBINUMA YASUMITSU
IPC: G01R31/12
Filed: 1980-05-07
Abstract: PURPOSE:To make use of a noise eliminator effective and eliminate measurement errors owing to the noise eliminator by differing the frequency of a measuring power source and that of surrounding power source. CONSTITUTION:The frequency of a measuring power source 3' is differed, for example, 60Hz when the power source frequency of surrounding electric installations is 50Hz, and 50Hz when it is 60Hz. Hence, the pulse groups in which external noise and signal are mixed are detected with a partial discharge detector, but even if the external noise and the signal are of the same polarity, only the signal can be taken out by on and off of a gate 8 because there is a time lag in the generation of the respective pulses, whereby the anihilation of the signal by the removal of the external noise is averted.

Filed: 1989-03-13
Abstract: PURPOSE:To process the picture data at a high speed by using the coded data as an address to separate the picture data into the densities of three primary colors for production of the density data before the picture data is stored in a picture memory. CONSTITUTION:The hardware is added to decode data with no use of a CPU of a recording device after providing a logic arithmetic circuit before the picture data containing the encoded density information is sent to a picture memory 6. A decoding means consists of an S-RAM 5, a counter 4, and a data latch mechanism 2. For the inputted data, the picture codes are inputted to the lower rank addresses as the memory addresses of the S-RAM 5. At the same time, the higher rank addresses serve as the selection addresses of three primary colors and the output serves directly as the density data corresponding to the three primary colors. Thus the picture data is converted at a high speed.

Abstract: PROBLEM TO BE SOLVED: To provide a character recognition device with which learning is enabled without increasing the size of learning dictionary by linking the feature of character to be learnt with the feature of character already registered on the learning dictionary when learning the character of the already learnt code. SOLUTION: When the feature of an erroneously recognized character is sent to a learning part 50 by a feature extracting part 30, while referring to a learning dictionary 70, the learning part 50 investigates whether the character of the same code as the character to be learnt is already learnt or not.
