Title: Magnetic resonance imaging apparatus
Inventor: KUHARA SHIGEHIDE
IPC: A61B5/055
Filed: 1988-01-22
Abstract: PURPOSE:To obtain water and fat separated image as real part and imaginary part images within a short time by one imaging, by setting the time from excitation to data collection so that water and fat signals have 90 deg. phase difference to obtain a sequence of ultrahigh speed imaging. CONSTITUTION:The time from the excitation of a nuclear spin to the start of data collection is adjusted so that the signals from water and fat mutually have 90 deg. phase difference. In a pulse sequence, a reading gradient magnetic field Gr and an encoding gradient magnetic field Ge are removed and only a high frequency magnetic field rf and a slicing gradient magnetic field Gs are used and the generated echo signals are collected as data. When these data are subjected to unidimensional Fourier transform, water and fat spectra are obtained. In the case of DELTAtau=0, water and fat spectra are obtained as the spectra having the same code of a Real part like a water spectrum 23 and a fat spectrum 24. By adjusting DELTAtau from this state, the fat spectrum 24 is adjusted so as to be generated in a state separated into an Imaginary part.

IPC: G06F12/08
Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To reduce time for retrieving its own node cache by controlling the hit rate of cache, retrieving server only when information does not exist when the hit rate is high, retrieve-requesting a server first and retrieving a cache within its own node next when the hit ratio is low. SOLUTION: When a past hit rate is higher than a set value, server retrieval request processing 2B requests retrieval to the server 28, and after than client retrieval processing 3B is executed. Then data presence/absence judging processing 4A judges whether its own node information exists or not, and when not existing, a retrieval is requested to the server. When the hit rate is low, server retrieval request processing 2B requests retrieval to the server 28, and then client retrieval processing 3B is executed. The server starts the retrieval of server information with the retrieval request from its own node. When information is found in the cache of its own node in the middle of retrieval, server retrieving processing is stopped.

Title: Test device for semiconductor integrated circuit
Inventor: KOBAYASHI MASAHIRO
IPC: G11C29/56
Filed: 1988-01-21
Abstract: PURPOSE:To decide whether or not the integrated circuit is normal by comparing parity information on an expected output value with the parity calculation result of the output value of the integrated circuit. CONSTITUTION:A ROM tester generates a test address by an address generation part and sends it to an expected value parity storage part and a device to be tested. The expected value parity storage part is stored with only the data- directional even parity of expected value data. For example, when expected values are 35H, 8CH, DOH, AAH..., their even parity values are 0, 1, 1, 0.... When an address is inputted, the device to be tested outputs storage contents corresponding to it and the output is inputted to a parity arithmetic part to calculate the even parity immediately. For example, when the output of the device to be tested is 25H, the even parity is 1. Then the even parity 0 of the expected value 35H is inputted to and compared by a quality decision part. In this example, the comparison result is dissident and it is decided that the tested device is defective.
