IPC: G12B5/00
Filed: 1990-06-11
Abstract: PURPOSE:To reduce shock force generation mechanism to put on a moving object and minimize and lighten the device by providing a spring made of a shape memory alloy to produce an attracting force and repelling force, and a shock force generation mechanism having a generator for magnetic force or electrostatic force. CONSTITUTION:To move a moving object means 1 to the right, electric current is supplied to a generator 4 for magnetic force or electrostatic force to generate larger attracting force between the mass 1 and an inertia body 2 than the friction force operating on the mass 1, and the mass 1 receives a rightword force to move to the right. At this moment, the reaction force to the mass 1 is mitigated by a buffer spring 6 and a shape memory alloy made spring 3. Conversely to move to the left, a control current is sent to the spring 3 to heat up over the critical temperature in a short time. Then the spring 3 is reversely transformed to generates a larger elastic force than the friction force acting on the mass 1, and then the mass slightly moves to the left. The reaction force to the mass 1 at this moment is mitigated by the spring 6. On the contrary, it is possible to generate a repelling force by the generator 4 to move the object 1 to the right and attracting force by the spring 3 to move it to the left.

Title: Ink-jet recording head
Inventor: YAMANAKA AKIHIRO
IPC: B41J2/16
Filed: 1998-05-19
Abstract: PROBLEM TO BE SOLVED: To prevent a top plate from being deformed because of pressure fixing of the top plate and a substrate and prevent printing from being inclined due to the deformation by setting a deep part at a butt part where an orifice plate having an ink discharge opening connected to one end of an ink passage groove butts against an end part of the substrate. SOLUTION: A deep part 7 is set in an orifice plate 4 to correspond to an end part of a heater board 1. Many fine recessed parts and wall parts are formed in the vicinity of the end part of the heater board 1. When the heater board 1 is pressure fixed to the orifice plate 4, a force concentrating to a contact face is dispersed because a wall of a part pressed strongly is broken, and the end part of the heater board 1 is brought into a state equal to when pressed to a soft elastic body. The orifice plate 4 is thus restrained from deformation. Good printing without bending at the end part is achieved with no cost rise resulting from a size increase of the heater board.
