Filed: 1997-12-17
Abstract: PROBLEM TO BE SOLVED: To provide an ink jet printer in which an auxiliary operation of suppressing generation of satellite drop and a stabilized jetting operation of ink drop are realized, and a recording head driver and driving method for ink jet printer. SOLUTION: A piezoelectric element 116a for jetting ink drop and a piezoelectric element 116b for suppressing generation of satellite drop are provided for each ink chamber 114 corresponding to a nozzle 118 and applied with driving signals. Upon starting contraction of the ink chamber 114 due to displacement of the element 116a, the driving signal is raised to a specified level for preventing displacement. Consequently, the element 116b is prevented from being displaced in the expanding direction of the ink chamber by a jetting pressure produced through displacement of the element 116a. The jetting pressure produced from the element 116a is used for jetting an ink drop substantially with no loss thus ensuring stabilized ink jet in which fluctuation is suppressed.

Filed: 1998-12-09
Abstract: PROBLEM TO BE SOLVED: To provide a torsional stress absorbing shaft for a seat belt device which is capable of reducing the webbing drawing force step by step with a simple constitution. SOLUTION: (A) A torsion bar 24 is formed of three layers. When the torsional stress is loaded in the torsion bar 24, and reaches the yield point (P1), the torsional angle is increased, and (B) an outer layer 40 is fractured. Thus, the torsional stress is reduced approximately to the yield point (P2) of an intermediate layer 42 and an inner layer 44, and when the reduced torsional stress is loaded, the torsional angle is further increased. When the intermediate layer 42 is fractured (C), the torsional stress is reduced approximately to the yield point (P3) of the inner layer 44. By forming a multi-layered structure and fracturing it by layer, the force to be applied to the webbing can be reduced step by step, and the reaction on an occupant from the webbing is reduced thereby.

Filed: 1998-12-10
Abstract: PROBLEM TO BE SOLVED: To reduce the change of a color with time by constituting an elastically deformable grip member which is arranged at the gripping section, of two kinds of elastic bodies of which the colors are different, and preferably, of which the temperatures for complete melting are different, and arranging one of them into a marble-state. SOLUTION: For a writing utensil 1, a grip member 4 is arranged at the gripping section 3 of a barrel cylinder 2. Then, the grip member 4 is constituted of two kinds of elastic bodies, an elastic body 4a, and an elastic body 4b wherein the temperature for the complete melting is higher than that of the elastic body 4a, and in addition the color is different from that of the elastic body 4a. When an injection molding is performed using the mixed material of the elastic bodies 4a and 4b, the resin temperature is set higher than the temperature by which the elastic body 4a completely melts, and lower than the temperature by which the elastic body 4b completely melts. Since the elastic body 4b does not completely melt, the elastic body 4b is arranged in the elastic body 4a under a marble-state. By this constitution, the change of the hue with time becomes less.
