Title: Cursor controller
Inventor: SCHMIDT MICHAEL
IPC: G06F3/0354
Filed: 1987-10-23
Abstract: PURPOSE:To prevent the operation vectors of a control ball from varying when the control ball is started only in one coordinate axis direction by varying the axial diameter of rotary rolling bodies which contact the control ball. CONSTITUTION:At least one of the rolling bodies 4 and 5 which rotate is varied in diameter axially so that the rolling bodies 4 and 5 contact the control ball 3 at two contacts. Namely, the control ball 3 is given momentum as shown by an arrow 17 and then when the control ball is left as it is, the control ball 3 is accurately guided not by the friction at contacts 5a and 5b of the rolling body 5, but principally by the friction at contacts 4a and 4b of the rolling body 4. The control ball 3 is guided at the contacts 4a and 4b (where the statical friction at those contacts exceeds the slide friction at the points 5a and 5b), namely, only the rolling body 4 rotates to maintain rotary momentum in the initial direction. This makes it secure that a cursor moves completely linearly as shown by 2'.

Title: Magnetic resonance imaging apparatus
Inventor: KAJIYAMA KOJI
IPC: G01R33/32
Filed: 1989-10-18
Abstract: PURPOSE:To suppress artifacts so as to obtain an image free from blur without an extension of measurement time by correcting a difference of longitudinal magnetization caused by a longitudinal relaxation time before start of every projection by using a free induction damping signal. CONSTITUTION:A magnetic resonance imaging apparatus is equipped with a central processing unit(CPU) 1, a sequencer 2, a transmission system 3, a magnet 4 for generating static magnetic field, a reception system 5 and a signal processing system 6. Assuming that a magnitude of longitudinal magnetization before start of n-th projection is Mn-1, a free induction damping(FID) signal turns out to be a function of Mn-1 and a spin echo signal also a function of Mn-1. Therefore, this free induction damping(FID) signal is utilized for removing an influence of a longitudinal relaxation from the spin echo signal. It is thus possible to reduce artifacts due to a difference of longitudinal magnetization before start of every projection and to obtain a clear image free from blur.

Abstract: PURPOSE:To improve the performance of a handwritten character recognition by preserving feature in the direction of the stroke of an original pattern for a binarized character pattern, and obtaining the feature pattern in which the dislocation of the stroke is corrected. CONSTITUTION:The binary pattern of a 2-dimensional picture is stored into a binary pattern storing means 1, a characteristic histogram extracting means 2 reads the binary pattern from the means 1, and the histogram with the characteristics determined for horizontal and vertical directions is generated. An initial feature extracting means 4 reads the binary pattern from the means 1, and extracts the geometric initial characteristics corresponding to each picture element. A normalizing function calculating means 3 calculates an accumulated curved line from the histogram in the horizontal and vertical directions generated in the means 2, and then the non-linear normalizing function in the horizontal and vertical directions is obtained. An initial feature normalizing means 5 normalizes the initial characteristics obtained by the means 3 by the non-linear normalizing function in the horizontal and vertical directions, and obtains the feature pattern.

And, when a zero or negative voltage is applied to a gate region 5, a depletion layer is extended from the gate region 5 to the cathode region 2 to shut off a current which flows through a high resistivity region 4 between a cathode region 2 and an anode region 3, and even a region separate from the gate bonding pad 7 becomes small in a gate resistance component, so that a voltage is restrained from dropping. Therefore, a gate electrode can be decreased in resistance and a semiconductor device, which can prevents the concentration of a current from occurring at turn-OFF, can be obtained.
