Title: Bimorph piezoelectric element
Inventor: OKAMURA TOSHIHIKO
IPC: H01L41/09
Filed: 1993-07-09
Abstract: PURPOSE:To prevent the characteristic of an element from being lowered and to prevent the element from being destroyed even when a steam sterilization treatment or the like is executed by a method wherein a piezoelectric substance is provided with the Curie temperature at a specific temperature or higher and a material at a glass transition temperature or higher is used as an adhesive. CONSTITUTION:The Curie temperature of a piezoelectric substance is set at 200 deg.C or higher, preferably at 220 deg.C or higher. When the Curie temperature is lower than 200 deg.C, the polarization of the piezoelectric substance is loosened when heat is applied in a sterlization treatment or the like. In addition, it is preferably that the dielectric constant of the piezoelectric substance is at 1500 or higher and that an electromechanical coupling coefficient kp is at 0.5 or higher. When the dielectric constant of the piezoelectric substance is lower than 1500 and the electromechanical coupling coefficient kp is smaller than 0.5, the characteristic of an element is lowered. When a material as specified in the above is used, the characteristic of the element is not lowered and the element is not destroyed even when a steam sterilization treatment or the like is executed.

Title: Production of powder coating material from fine by-product powder
Inventor: NAGAO TETSUO
IPC: C09D5/03
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To produce a powder coating material capable of forming a coating film without defects in its properties from a fine by-produce powder obtd. as a by-product in the grinding step after kneading a powder coating material compsn. and to thereby recycle the by-product powder by molding the powder into granules with specified sizes and using the granules as a raw material compsn. SOLUTION: A fine by-produce powder is compression molded, e.g. with a two-roll mill pref. at 60 deg.C or lower, still pref. 40 deg.C or lower, into granules with granular sizes of 1mm or higher, pref. 1-50mm, still pref. 5-30mm, and is used as a powder coating raw material compsn. A granular size lower than 1mm degrades the mixing properties as a powder coating material while one higher than 50mm reduces the amt. per unit time of the powder flowing into a kneader, increasing the dwell time in the kneader, and deteriorating the properties of the resultant coating material. The compression molding temp. is pref. low to avoid the problems due to heat hysteresis.

Abstract: PURPOSE:To control the movement extent of an objective part in its tracking direction without damaging a coil nor decreasing the efficiency of a magnetic circuit by providing a support member and/or yoke part with a control part which controls the movement extent of the objective part in the tracking direction. CONSTITUTION:A projection 21 is so formed to abut on the external yoke 10c of the yoke 10 freely and its projection extent is set so that the inner peripheral surface of the coil 8 does not abut on the center pole 10a of the yoke 10 when the projection 21 abuts on the external yoke 10c. When the objective 1 is moved and controlled in the tracking direction, the projection 21 abuts on the external yoke 10c, and consequently the movement extent in the tracking direction is controlled. In such a case, the coil 8 does not abut on the center pole 10a, so neither the breaking of the coil 8 nor the peeling of a film is caused, the gap of the magnetic circuit is not held properly. Consequently, the optical head is prevented from becoming faulty and the stabilization and reliability improvement of the product are attained.
