Title: Manufacture of ball-point pen
Inventor: OGURA NORIO
IPC: B43K7/02
Filed: 1997-12-24
Abstract: PROBLEM TO BE SOLVED: To expand the selection range for ink materials by a method wherein the volume of air bubbles is made larger by a vacuumized atmosphere, and the specific gravity difference with a liquid part is further expanded, and the removal of bubbles is performed by a weaker centrifugal force. SOLUTION: Invisible air bubbles in a ball-point pen, further speaking, in an ink 20 and in an ink following body, are expanded by vacuumization, and removed to the outside of a system. Therefore, the removal of air bubbles theoretically can be performed by a weaker centrifugal force than a case of a normal pressure if the atmospheric pressure is lower than a normal pressure, but the pressure of the atmosphere is preferable to be 0.5 atmospheric pressure or lower. Under this atmosphere, air bubbles become an approx. twice larger volume, and the specific gravity difference between a liquid part and the air bubbles becomes roughly twice larger as well. Further speaking, it is preferable to be 0.2 atmospheric pressure or lower. Especially, when a water-soluble ball-point pen is built up, caution is required for an excessive reduction of the atmospheric pressure. The boiling point for water under 0.2 atmospheric pressure is approx. 60 deg.C, and even by a temperature ascent which is generated by a friction or the like between a centrifugal machine and air, as long as the machine is not continuously used, the ink 20 does not boil, but at 0.01 atmospheric pressure or lower, the boiling point of water is lower than 10 deg.C.

Title: Three-dimensional curved surface traveling carriage
Inventor: INAMI SHOICHI
IPC: B23K9/12
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To prevent a sudden attitude change even if a carriage travels on the three-dimensional curved surface by mutually connecting a pair of left/right wheel parts through the joint part having one degree of freedom, and arranging plural wheels in the advance direction in the respective wheel parts. SOLUTION: A pair of left/right wheel parts 1A and 1B are mutually connected by the joint part 30 having one degree of freedom. In this case, the joint part 30 is composed of a shaft 31, a bearing 32 and the recessed part 33. The shaft 31 arranged on the side of the wheel part 1A is fitted in the cylindrical recessed part 33 arranged on the side of the wheel part 1B to be rotatably supported by the shaft 31 installed in the recessed part 33. Therefore, when a carriage travels on the three-dimensional curved surface, either one wheel part 1A or 1B among the left/right wheel parts 1A and 1B rotates according to a recess/projection on the curved surface. A suddent attitude change is not caused as usual since four wheels 141 , 142 , 151 and 152 are always grounded on the three dimensional curved surface.

Abstract: PROBLEM TO BE SOLVED: To detect an overshoot, an undershoot, and a waveform deformation produced in an output period of digital signals output from a semiconductor digital circuit at a low cast in a short period. SOLUTION: If an overshoot occurs, a peak hold circuit 13 holds a high level, when an undershoot occurs, a peak hold circuit 15 holds a high level and when a waveform deformation occurs, a peak hold circuit 14 holds a high level. In all these cases, a high level is output from an OR circuit 17 so as to detect a defective product. When a normal waveform occurs because all peak hold circuits 13, 14, and 15 hold a low level, a low level is output from the OR circuit 17 so as to detect a nondefective product.
