Title: Protecting circuit for complementary metal oxidized film semiconductor
Inventor: OOHATA MICHINOBU
IPC: H01L29/78
Filed: 1981-09-29
Abstract: PURPOSE:To effectively detect latchup phenomenon by connecting C-MOS group through an overcurrent detecting element, a switching element to a power source and inputting the output of a detecting element through a filter to a comparator and controlling the switching element with the output of the comparator. CONSTITUTION:A C-MOS group 4 of an input/output unit which feasibly occurs a latchup phenomenon is, for example, connected through an overcurrent detecting element 2 and a switching element 3 to a power source voltage VSS. The output side A of the element 2 is connected through a filter 11 to a C-MOS comparator 12, and the output of the comparator is connected to a flip-flop 13, thereby controlling the switching element 3. When the group 4 normally operates, the operating current flows in pulsating state. Accordingly, the flip-flop 13 does not invert. When it becomes latchup state, the output of the filter 11 decreases, thereby operating the comparator 12. Since the flip-flop 13 is thus inverted, the element 2 is interrupted.

Title: Pulse sequence for acquiring raw data and nuclear spin tomography
Inventor: KIEFER BERTHOLD
IPC: G01R33/48
Filed: 1999-06-01
Abstract: PROBLEM TO BE SOLVED: To avoid resolution loss at the time of a turbo spin echo sequence by executing a phase coding of a nuclear resonance signal with time elapsed that echo generated after exciting is made to correspond to a segment from a related line of raw data matrix. SOLUTION: A line of raw data matrix is divided again into segments as when a conventional technique is used. In this case, the segments are not made to correspond to specified echo numbers and are made to correspond to specified exciting. Nine echoes of first excitingexc1 are written in a center segment, an echo of second excitingexc2 is written in a segment S1 continuous in a positive direction and all the echoes of third excitingexc3 are written in a segment S-1 continuous in a negative direction (subsequently in the same way). By an array of this form, echo amplitude and T2 weight of an edge segment are corresponding to echo amplitude and T2 weight of a substantially center segment. Therefore, resolution loss due to lowering of T2 is not generated.

Whether the image is vertically long or horizontally long is confirmed inside the image controller 4. The image is displayed as is on a monitor 10 as a reproduction image by an image display IC 6, when it is horizontally long but the image is displayed after being rotated by 90 deg. to be vertical if it is vertically long. Thus, images stored in the camera are easily confirmed, even when a plurality of images are displayed by means of index.
