Title: Driving method for piezoelectric actuator
Inventor: TAKAHASHI SADAYUKI
IPC: H01L41/09
Filed: 1990-09-21
Abstract: PURPOSE:To make it possible to make a piezoelectric actuator withstand to a long-time continuous use under a high humidity by a method wherein a DC voltage, on which an AC voltage of a fine amplitude is superposed, is applied. CONSTITUTION:In a piezoelectric actuator constituted by a method wherein piezoelectric ceramic layers 1 and metal electrode films 2 are alternately laminated and are integrally formed, the films 2 are electrically parallel-connected by a conductive film 4 via insulators 3. Two electrode leads 6 are led out from the film 4 and when a voltage is applied between these leads 6, the element is expanded and contracted in its height direction. At this time, when an AC voltage of a fine amplitude is used to a DC voltage as an applying voltage, the DC voltage generates a desired displacement in the actuator and the AC voltage of a fine amplitude, which is superposed on the DC voltage, generates heat in the element. This heat generation is one due to a dielectric loss. When the heat is generated in the element, the temperature of the element itself becomes higher than an environmental temperature encircling the element. As a result, moisture is prevented from penetrating into a sheathing resin and the electrical destruction of the element is prevented.

Patent JP-S61128212-A (JP)
Title: Reinforcing method of optical fiber juncture
Inventor: MURATA NORIO
IPC: G02B6/36
Filed: 1984-11-27
Abstract: PURPOSE:To obviate an increase in the transmission loss at the juncture during molding or when temp. is low by injecting a melt-liquid crystalline thermoplastic resin which exhibits a low coefft. of linear expansion into molds after setting the juncture into the mold then forming a coating layer around the juncture. CONSTITUTION:Any polymer which is liquid crystal in a molten state is usable as the melt-liquid crystalline polymer. Any polymer consisting of polyethylene terephthalate and P-hydroxy benzoic acid is particularly suitable among such polymers. The welded juncture of optical fibers is set into upper and lower metallic molds 1, 2 and after the molds are clamped, the heated melt-liquid crystalline polymer is poured through a pouring port 3 into the molds. The polymer receives the shearing stress in the longitudinal direction of the fiber and consequently a molecular orientation arises in the longitudinal direction to decrease the coefft. of linear expansion. The polymer packed around the juncture set in a resin packing chamber 4 cures immediately and the juncture is thereby protected and reinforced. Since the melt-liquid crystalline thermoplastic polymer exhibiting the low coefft. of thermal expansion is used as a molding material, the increase in the transmission loss during molding or when low temp. is lessened.

Title: Filler for filling sealing resin and its manufacture
Inventor: OKUAKI YUTAKA
IPC: H01L23/29
Filed: 1986-10-22
Abstract: PURPOSE:To strengthen the adhesion force to sealing resin, to suppress its thermal expansion and to prevent the penetration of the moisture or the like by a method wherein a filler is formed in the form of a short fiber whose cross-sectional circumference is curved and whose both ends are shaped like curved surfaces and its contact face in the longitudinal direction is sufficient in relation to the sealing resin. CONSTITUTION:An inorganic fiber, e.g. a glass fiber, whose diameter is about several mum is prepared; this fiber is cut by means of a cutter or the like to shape a prescribed size, e.g. about several mum to several tens mum in length. The glass fiber which has become a short fiber is blown into a high-temperature furnace from above by means of a spreader or the like or is dropped by being sprinkled so that it can be exposed to the high temperature inside the furnace. During this process, the temperature of the furnace is adjusted to a value which is higher than the melting point of the flass fiber, e.g. about 1800 deg.C. The dropped glass fiber is heated at a prescribed temperature for a prescribed time; both ends formed after the cutting operation are melted and are transformed into the ends with curved surfaces. The shape of the dropped glass fiber is maintained after the fiber has been cooled at a temperature which is lower than the freezing point, and a filler 17 is obtained in the form of a short fiber whose both ends form curved surfaces. This filler is mixed with resin 18 in the resin-weight ratio of about 50-80%. A resin material 19 can be formed by distributing the filler uniformly.
