Title: Ball for ball point pen
Inventor: NAKATANI YASUNORI
IPC: B43K1/08
Filed: 1999-09-16
Abstract: PROBLEM TO BE SOLVED: To provide a ball for a ball point pen, with which broken lines are hard to develop during continuous writing and a smooth writability can be ensured. SOLUTION: In this ball for a ball pen, first holes A and second holes B, the average hole diameters of which are different from each other, are formed on at least the surface of a spherical body made of rigid material. Since the ball is rotated under the state that pigment and ink are held in the holes B, the average hole diameter of which is larger than that of the hole A, between the first and the second holes A and B, the ball easily rotates, resulting in dipping out much ink. In addition, due to the presence of the hole A, the average hole diameter of which is smaller than that of the other hole, the adhesion of the ink to the ball becomes higher and simultaneously the dipping-out effect of the ink is improved.  Thus, the rotatability of the ball and the adhesion of the ink are improved and the efflux of the ink becomes larger, resulting in making the conventional development of broken lines difficult and allowing to ensure a smooth writability.

Title: Combustion device
Inventor: ASOU TOMOMICHI
IPC: F23D14/66
Filed: 1994-10-26
Abstract: PURPOSE: To miniaturize the device structurally, save the energy, and enable reduction of NOx in the cinbustion. CONSTITUTION: A rotary body 7 has a honeycomb constitution and axially a plurality of passageways. Each of the passageways is formed into a flame hole at the end, where a flame is formed, and the combustion gas flows in the reverse direction through the respective passageways of the rotary body 7 opening to a combustion chamber 12. Since the passage of the combustion gas is stationary, the temperature of the rotary body 7 rises. The rotary body 7 is rotated by a motor 14 so that fuel-air premix which passes through the rotary body 7 can be preheated continuously and the combustion gas, recirculated together with the fuel-air premix. Therefore, the thermal efficiency can be improved by preheating and NOx in the combustion gas can be reduced.  Since a flame is formed at the end of each passageway in the rotary body 7, the use of the rotary body 7 as the combustion part enables an apparatus to be made structurally smaller.
