Patent JP-H09202088-A (JP)
Title: Writing instrument
Inventor: MATSUMOTO KAZUAKI
IPC: B43K7/10
Filed: 1996-01-24
Abstract: PROBLEM TO BE SOLVED: To enable an ink to be naturally guided out to a pen point without the necessity to initiate the suction of the pen point by forming a capillary created by a gap communicating with the center of an ink guide core with a maximum capillary width set smaller than the minimum groove width of a reservior groove width so that the ink suction force of the capillary is stronger than that of the reservior groove. SOLUTION: An ink guide core 7 has a cross section consisting of an almost radially formed gap as a capillary formed continuously in the longitudinal direction of the ink guide core 7, through which an ink flows. In addition, the maximum width of the capillary is set not larger than the minimum width N of the reservior groove 3, so that the capillary attraction of the capillary is stronger than that of the reservior groove 3. After assembly, the ink comes into contact with the rear end part of an ink reservior 5 and the rear end part of the ink guide core 7, if the pen point 10 is turned downward or set on the side. However, the capillary attraction of the ink by the largest capillary of the flow passageway of the ink guide core 7 is stronger than that of the smallest capillary of the reservior groove 3 of the ink reservior 5.  Thus the ink finds its way into the ink guide core 7 instead of into the reservior groove 3, and is naturally guided to the pen point 10 through a center core 8.

Title: Method for numerically analyzing physical quantity
Inventor: YABE TAKASHI
IPC: G06F19/00
Filed: 1989-02-10
Abstract: PURPOSE:To obtain the solution of a hyperbolic type equation as a practically very satisfactory approximate solution by giving a function value as the solution of the hyperbolic type equation and is deviation with respect to two variables and performing numerical analysis of the physical quantity by interpolation dependent upon a cubic polynomial consisting of the distance from one of these two variables to a variable intermediate between them. CONSTITUTION:The function as the solution of the hyperbolic type equation and its differential calculus exist, and two variables sufficiently close to each other and a variable intermediate between them are set; and when values of the function for two variables and their deviations are given, the value of the function for the intermediate variable is interpolated by the cubic polynomial consisting of the preceding given function value, its deviation, and the distance between one of two variables and the intermediate variable. Thus, numerical analysis of the physical quantity which has a high degree of satisfaction and supplies sufficient data for production of an actual machine is realized by numerical simulation using a computer without actually executing the expensive analytic experiment of the physical quantity which takes a long time.

Title: Stopping circuit for dc motor
Inventor: MARUYAMA YOSHIJI
IPC: H02P3/12
Filed: 1990-02-08
Abstract: PURPOSE:To rapidly stop a DC motor by closing a relay contact inserted in series with a resistor connected in parallel with the motor at the time of stopping to actively short-circuit the inducted electromotive force of the motor. CONSTITUTION:A contact switch 11 is opened at the time of stopping to stop a relay 13, its relay contact (make contact) 3 is opened, photocouplers 7, 8 are stopped, and a driving circuit C is stopped. In this case, since the relay contact (break contact) 1 of a stopping circuit E is closed, a generated voltage from a DC motor 5 is eliminated since a short-circuit current I1 flows through a resistor 6. This resistor 6 is to limit a current, and its resistance value can be selected for sufficiently smaller than the impedance of the motor 5. Accordingly, when the motor is stopped, the contact 1 is closed to actively short-circuit the voltage generated from the motor 5.

Title: Projection welding method
Inventor: FUKAYA YOSHINORI
IPC: B23K11/14
Filed: 1988-02-12
Abstract: PURPOSE:To save energy of a welding current by partitioning a point and its vicinity to come into contact with a projection at the thin plate side of the surface of a thick plate with the peripheral surface via proves or the difference in level of height to balance almost heat capacity between members to be joined. CONSTITUTION:The thin plate 1 is superposed on the thick plate 2 and the projection 3 at the thin plate 1 side is brought into contact with the contact point 5 at the thick plate 2 side and subsequently, while electrodes 6 and 7 pressing the members 1 and 2 to be welded, the welding current is carried between the projection 3 and the projection contact point 5. Since the projection contact point 5 and the vicinity 2a of this contact point of the upper surface at the thick plate 2 side are then partitioned from the other remaining surface 2b via the grooves 4, the radiation of heat of the contact point 5 and the vicinity 2a of the contact point to the remaining surface 2b side is suppressed effectively. As a result, even when the projection 3 is provided to the thin plate 1 and projection welding is performed, the heat capacity of both weld zones 3 and 5 between the members 1 and 2 to be welded is almost balanced by a function of the grooves 4 at the thick plate 2 side and satisfactory projection welding can be performed with the low welding current.
