Title: On-line character recognition device
Inventor: IKEHATA YOSHIKAZU
IPC: G06V30/10
Filed: 1997-06-09
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for a special operation for inclination correction and to reduce burdens on a writer by correcting inclination by using the inclination of a pen on the input surface of a character obtained when the character is inputted. SOLUTION: A character input part 1 inputs a character pattern written with the pen, an inclination detection part 2 detects the inclination (inclination angle) of the pen on the input surface of the character input part 1 and a first inclination storage part 3 holds a predetermined inclination angle. A inclination correction part 4 corrects the inclination of the character pattern by using the inclination angle detected in the inclination detection part 2 and the inclination angle held in the first inclination storage part 3 and then, a recognition part 5 recognizes the character pattern whose inclination is corrected. In this case, the inclination detection part 2 obtains an angle formed by the projection of the pen to the input surface and a coordinate axis (x) as the inclination angle. The first inclination storage part 3 holds the inclination angle expected to be suited to many writers in the case of performing write so as not to obliquely incline the character beforehand.

Title: Method and apparatus for cooling oxide superconducting coil
Inventor: MORITA MITSURU
IPC: F25D3/10
Filed: 1991-05-28
Abstract: PURPOSE:To prevent the magnetic flux of a superconducting coil from creeping by evacuating liquid nitrogen to cool the coil at the triple point temperature of nitrogen. CONSTITUTION:After fluid nitrogen 7 is filled into a housing chamber 1 for an oxide superconducting coil 6, it is cooled to the triple point temperature (63.1K) of nitrogen while evacuating it by means of an evacuating pump 2, and then the coil 6 is stably cooled while it is kept under a constant temperature. On the other hand, upon filling nitrogen 7 into a spare evacuating chamber 8 to cool it to the triple point temperature through evacuation, nitrogen 7 is replenished into the chamber 1, so that the coil 6 is cooled at a constant temperature for a long period by repeating such replenishing steps. Thus the creeping of the magnetic flux of the coil 6 can be prevented.

Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To insert and take out a memory medium to a monitor supporting body without damaging the medium by allowing the memory medium in the monitor supporting body to be discharged only when an angle of a monitor panel to a predetermined face is detected to be a perfectly open state. SOLUTION: A tilt mechanism 50 changes an angle of a monitor panel 10 between a perfectly close state where a rear face of the monitor panel 10 is opposite to a body front face (predetermined face) 29, and a perfectly open state where a monitor front face of the monitor panel 10 is perpendicular to the body front face 29.

Title: Condenser
Inventor: MIYOSHI NORIOMI
IPC: G02B5/00
Filed: 1980-10-29
Abstract: PURPOSE:To condense light to small area (of optical fiber, etc.) efficiently without leaking light out, by decreasing the refractive index of a condenser, which is sectioned circularly and decreases in diameter lengthwise, from the center of the area to the circumference. CONSTITUTION:Light is emitted from the largest-diameter part 2L of a circularly sectioned condenser 2 having the distribution that the refractive index IR-1 of the section S-1 decreases from its center part to the circumferential part. Light approaching the flank of the condenser 2 increases light in velocity rapidly and is bent to the center axis of the condenser 2 at any time. Therefore, light traveling from the largest-diameter part 2L to the smallest-diameter part 2S, while waving as shown by the solid line, reaches the smallest-diameter part 2S without leaking out. AY this time, when the refractive index decreases to the smallest-diameter part even lengthwise, the leakage of light is further decreased.

Title: Microwave oven
Inventor: INOUE MASANOBU
IPC: G01G23/01
Filed: 1989-06-14
Abstract: PURPOSE:To develop various types of microwave ovens which are equipped with the same type of weighing elements and are different in maximum weighing capacity and resolution, by a method wherein a load exerted from a table to a support rod is magnified or reduced at a specified transmitting ratio and transmitted to a weighing element. CONSTITUTION:A magnetron 5 attached on the wall of an oven 2 sends high-frequency waves into a compartment of the oven. A table 1 is located in the compartment of the oven 2. The total weight of an object to be detected and the table 1 is transmitted downward through a support rod 3. The load exerted on the point of force 13 is magnified or reduced at a load transmitting ratio of a lever and transmitted to an action point 14. When the weight is transmitted from a sensor compressing part 11, an elastic body on the upper portion is deformed and the distance between electrodes is shortened resulting in a reduction in the electrostatic capacity between the electrodes. Various kinds of specifications regarding the magnitude of maximum weighing limit and resolution can be satisfied only by changing the setting position to change the load transmitting ratio of the lever even when the same sensor element and mechanical components are used, so that a wide range of types can be developed.
