Title: Magnetic resonance imaging method
Inventor: YODA KIYOSHI
IPC: A61B5/055
Filed: 1987-09-25
Abstract: PURPOSE:To obtain a magnetic resonance imaging method imparting good contrast and a good S/N ratio, by exciting and saturating the spin in a predetermined thickness while applying the first inclined magnetic field in the direction vertical to the plane of a receiving coil and exciting the spin in a slice having a certain thickness while applying the second inclined magnetic field in the direction parallel to said plane. CONSTITUTION:The first inclined magnetic field is applied in an X-direction with respect to the Z-Y plane of a receiving coil 2 to excite the spin in the predetermined thickness of a human body 1 in the X-direction. By continuously applying the first inclined magnetic field, the phase of the spin falls into disorder and the spin of the first region 7a is saturated at last. A 90 deg.-pulse is applied while the second inclined magnetic field is applied in a Z-direction. By this method, the spin in the slice of the human body 1 having a certain thickness in the Z-direction is excited but, since the sin of the first region 7a is saturated, the spin only of the second region 7b is excited. This operation is repeated while the intensity of the third inclined magnetic field is anithmetically changed to obtain a plurality of spin echo signals S which are, in turn, subjected to two-dimensional Fourier transform with respect to a time and the intensity of the third inclined magnetic field to perform the imaging of a desired slice.

Title: Semiconductor device
Inventor: KINOSHITA HIROYUKI
IPC: H01L29/78
Filed: 1999-08-25
Abstract: PROBLEM TO BE SOLVED: To obtain a highly stable high performance semiconductor device in which finer atterning can be effected while suppressing short channel effect. SOLUTION: Impurity concentration in the channel region 30 of an MOS transistor is set higher at the end of a surface depletion layer 26 than on the surface of a semiconductor substrate 20 by providing an impurity concentration profile of linear or higher order function or Gaussian distribution. Since elongation of source and drain depletion layers 27, 28 can be controlled and the depletion layer regions 29s, 29d not contributing to the threshold voltage of a MOS transistor can be minimized, short channel effect is suppressed resulting in a highly stable high performance semiconductor device in which finer patterning can be effected.

Filed: 1988-09-22
Abstract: PURPOSE:To prolong the life of a lamp by providing a switching means, turning on a pulse only when a large amount of light is required and turning on the lamp at a prescribed amount of light in normal observation. CONSTITUTION:A lamp current changeover switch 27 is provided on the operating part of an electronic endoscope 1 to switch turning-on at a certain amount of light and turning-on of pulse.
