Title: Character font memory and character pattern generating device using same
Inventor: WATANABE KIYOSHI
IPC: G06K15/02
Filed: 1990-06-11
Abstract: PURPOSE:To generate a character pattern of high quality by including a flag which indicates whether or not a coordinate point is a point constituting the contour of the character pattern, the absolute coordinate values of a reference point, and relative coordinate values or the absolute coordinate values of the reference point. CONSTITUTION:The English letter 'H' is represented as coordinate values of plural points obtained by expanding the coordinate values of a control point starting at the coordinate values of coordinates A1 (coordinate reference point) with vectors. Coordinates points A1 and A1 are coordinate reference points which are not included in the contour constituting the character, namely, the flag which indicates whether or not they are points constituting the contour of the character pattern is OFF. In this case, only those coordinate reference points are represented as the absolute coordinate values of (X, Y). Consequently, a character in a complicate shape can be outputted with high quality over a wide character size range without any deterioration in the quality even after enlargement, reduction, or deformation arithmetic by making the segments uniform in thickness and holding symmetry of the segments.

Filed: 1994-06-30
Abstract: PURPOSE:To reduce stress leak current without making erasing and writing time longer and increasing the number of applying signals, by temporarily reversing the heights of potential between a word line and a bit line, source line and substrate at the time of data erasing and writing operation. CONSTITUTION:In erasing operation, bit line and source line are opened, and a high potential as a first potential is given to a p-type well, then a low potential as a second potential is given to a selection word line so as to emit electrons of a memory cell. Then, when the p-type well is to be lowered to a second potential, it is not fixed at a second potential immediately, and a lower third potential VR than the second potential is given thereto, then it is restored to the second potential after emitting a hole trap. Thus, the heights of potential between a word line and a bit line, source line and substrate are temporarily reversed at the time of data erasing and writing, so that stress leak current can be reduced without making erasing and writing time longer and increasing the number of applying signals.

Title: Simplified checker for air pressure of tire
Inventor: TOYOFUKU MASANORI
IPC: G01L17/00
Filed: 1996-05-21
Abstract: PROBLEM TO BE SOLVED: To effectively prevent the destruction and the damage of a simplified checker and to effectively prevent the generation of an air leak by a method wherein a means by which information on the air pressure of a tire is confirmed visually is installed in a state that it does not protrude from the surface of a tire wheel. SOLUTION: When the air pressure of a tire is within a required range, the air at the inside of a wheel flows into a body housing 11 from an air hole 13A. By the action of the air pressure, a diaphragm 14 is pushed and moved upward against the elastic force of a spring 15, and a display column 16 is pushed up from the lower side. As a result, the head part of the green display column 16 is advanced into a transparent cap 12 from the body hosing 11, it can be visually confirmed easily from the outside, and it is possible to check that the air pressure is at a prescribed air pressure.  In this manner, since a means by which information on the air pressure is confirmed visually is installed in a state that it does not protrude from a tire wheel, possibility that a simplified checker is damaged and destroyed when it collides with an edge stone is reduced, and the reliability of the checker is increased.

Filed: 1985-07-09
Abstract: PURPOSE:To reduce the production stage of a magnetic head and its production cost by using a chip obtained by coating the surface of a non-magnetic base plate with an amorphous magnetic substance as a back core. CONSTITUTION:The surface of the ceramic base plate 1 is coated with a stainless mask 3 having about 100-500mum thickness and forming two through holes by etching.
