Abstract: In a print head of a dot matrix printer, support frames carrying the piezoelectric elements of the print wires are seated in and bonded to a base unit to provide a rigid, unitary printing structure. The base unit has projections extending therefrom which define grooves into which the support frames are received. An adhesive or solder is used to adhere the support frames to the base unit. Silicone rubber may also be used to fill gaps between the support frames and the base unit and between individual print units.

Abstract: A device for magnifying displacement of an elongated piezoelectric element adapted to be displaced by application of voltage thereto, including a main frame extending along one side of the piezoelectric element and having a lateral projection for supporting one end of the piezoelectric element with respect to a direction of displacement of the piezoelectric element; a movable member mounted on the other end of the piezoelectric element with respect to the direction of displacement of the piezoelectric element; a first leaf spring fixed at its one end portion to the main frame; a second leaf spring fixed at its one portion to the movable member and disposed in opposed relationship to the first leaf spring; a rocking member fixedly connected to the other end of the first leaf spring and the other end of the second leaf spring and adapted to be rocked by flexing of the first and second leaf springs to be generated by the displacement of the piezoelectric element; a sub frame extending along the other side of the

Abstract: In a motion conversion mechanism for converting mechanical expansion and compression of a material, such as a piezo electric element, to the motion of the other material, provided are moving member arranged to be movable in accordance with the motion of the material along a predetermined direction, transmitting member for transmitting the movement of the moving member toward the other material along the predetermined direction, and regulating member for regulating the transmitting operation of the transmitting member so as not to be skewed from the predetermined direction. Thus, the transmitting operation of is accurately executed.

Abstract: A method of producing a device for magnifying displacement of a piezoelectric element adapted to be displaced by application of voltage thereto. The method includes a first step of forming a movable member integrally with a frame through a connecting portion in such a manner as a space for inserting therein a piezoelectric element is defined between the movable member and a base portion of the frame; a second step of fixing the leaf spring to the frame and the movable member; and a third step of forming a separation groove in the connecting portion to separate the movable member from the frame.

Abstract: A method for separating polysaccharides from tamarind seeds, comprising:(1) pulverizing the tamarind seeds to form particles of less than 80 microns;(2) dispersing the particles in an aqueous medium consisting essentially of water and 5-60% by weight of at least one water soluble organic solvent;(3) classifying the dispersion in a hydrocyclone, whereby the particles of polysaccharides descend to the bottom of the hydrocyclone, from which they are discharged; and whereby particles of other components, in particular proteins, simultaneously rise to the top of the hydrocyclone, from which they are discharged.

Abstract: A device for magnifying displacement of a piezoelectric element adapted to be displaced by application of voltage thereto, comprising a frame extending substantially parallel to a direction of displacement of the piezoelectric element; a movable member fixed to a first end of the piezoelectric element with respect to the direction of displacement; a first mount surface formed on said frame and extending substantially parallel to the direction of displacement; a second mount surface formed on the movable member and extending substantially parallel to the direction of displacement, which second mount surface is opposed to the first mount surface; a first leaf spring mounted at a first end portion on the first mount surface and extending substantially parallel to the direction of displacement; a second leaf spring mounted at a first end portion on the second mount surface and extending substantially parallel to the direction of displacement; and a rolling member fixed to second end portions of the first and seco
