Title: Suction nozzle for floor
Inventor: NAKAI KOICHI
IPC: A47L9/04
Filed: 1989-08-29
Abstract: PURPOSE:To effectively roll up dust extending for a long period and to heighten the cleaning- ability of the title implement by a method wherein on the outer surface of a rotary shaft in the form of a long axle, elastic material-made slide pieces each of which has a hollow part are provided along the longitudinal direction of the rotary shaft. CONSTITUTION:A rotary member 11 for cleaning is rolled at a high speed while a suction nozzle 4 for a floor is being traveled. In this way, to a floor surface A to be cleaned, a patting effect is applied with slide pieces 20 and the dust, such as fine dust, waste thread, hair and the like are stirred up and high rolling-up effect for the dust is obtained. Since each of slide parts 23 has a hollow part 24, the part in contact with the floor surface A is deformed and compressed toward the hollow part 24, and thus the part is very surly brought into contact with the floor surface A, and hence higher rolling-up effect is obtained. Furthermore, the floor surface A is not scratched by its deflection. When not brought into contact with the floor surface A, the contact part is restored to the original shape quickly and smoothly since the elastic force between the hollow part 24 and a side part 23a of the slide part 23 in the form of a rod is applied. In this way, even if the slide piece 20 repeats the compression and the restoration to the original shape everytime it is in contact with the floor surface A, it is always restored in the original shape, and hence high cleaning-ability can be maintained for a long time.

Title: Electrooptical part and its production
Inventor: KAWAGUCHI TATSUO
IPC: G02F1/035
Filed: 1994-09-16
Abstract: PURPOSE: To form an optical waveguide good in crystallinity according to a liquid-phase epitaxial method. CONSTITUTION: This electrooptical part is obtained by forming an electrooptical single crystal film constituted of the same kinds of elements as those of a substrate 9 comprising an electrooptical single crystal thereon according to a liquid-phase epitaxial method. A part 10 on the substrate side of the electrooptical single crystal film is formed by bringing the substrate 9 into contact with a melt at a prescribed temperature and the substrate 9 is then brought into contact with the melt at a higher temperature than the prescribed temperature to form a part 11 on the surface side of the electrooptical single crystal. Thereby, the refractive index of the part 11 on the surface side is higher than that of the part 10 on the substrate side.  A liquid phase and a solid phase are preferably made to coexist in the melt and the temperature of the melt is subsequently lowered to keep the liquid phase in a supercooled state. The substrate is then brought into contact with the liquid phase to respectively epitaxially grow the part on the substrate side of electrooptical single crystal film and the part on the surface side thereof.

IPC: H05K3/34
Filed: 1990-08-22
Abstract: PURPOSE:To enable a narrow pitch surface mounting type component to be arranged on a soldering plane and to dispense with a process that the surface mounting type component is tentatively fixed onto the soldering plane by a method wherein a solder bump is provided to the leads of an insertion mounting type component, the insertion mounting type component is mounted on a printed wiring board, and the solder bump is fused through reflow to solder. CONSTITUTION:An insertion mounting type component 4 is dipped into molten solder to enable a lead 4a to hold a solder 3c for the formation of a solder bump 3 (g), and then an insertion mounting type component 4 is inserted into a printed wiring board 1 (h). The insertion mounting type component 4 is soldered through a reflow method (i). The solder 3c is melt in this process and made to flow into a through-hole 1c through the lead 4a. By this setup, a surface mounting type component is prevented from being exposed to the jet flow of solder, and a narrow pitch surface mounting component can be optionally disposed on a soldering plane.

Title: Heat dissipating composite substrate
Inventor: YAMAKAWA TAKAHIRO
IPC: H05K3/38
Filed: 1991-08-07
Abstract: PURPOSE:To acquire an aluminum nitride-glass ceramics composite substrate which has good thermal impact resistance and heat dissipation properties by joining an aluminum nitride substrate and a glass ceramics substrate by epoxy adhesive containing aluminum nitride powder. CONSTITUTION:A heat dissipating composite substrate which is formed by joining an aluminum nitride substrate and a glass ceramics substrate by epoxy adhesive containing aluminum nitride powder. The content of the aluminum nitride powder is 20vol.% or more and a thickness of an adhesive layer of the adhesive is 2 to 200mum. Since an epoxy adhesive which adheres at a low temperature is used, generation of thermal stress during bonding and a difference of contraction amount are reduced. Furthermore, since the epoxy adhesive holds some elasticity after hardening, difference of contraction amount can be absorbed. Therefore, even if thermal impact is applied, the aluminum nitride substrate and the glass ceramics substrate do not peel off.

Abstract: PURPOSE:To enable printing operation to be prevented from delay by preventing magnetic force of a permanent magnet from decrease in the case of signal element driving, and by removing magnetic interference from other printing heads in the case of a plurality of elements simultaneous driving, by a method wherein a heel piece and a yoke are respectively made contact free and separation free by a transfer means, and in the case of contact a side magnetic path capable of constructing a magnetic path via on permanent magnet is established. CONSTITUTION:A piezoelectric element 17 impresses an electric field if necessary, and brings a second side path 16 respectively into contact with a heel piece 10 and a yoke 13 by contraction by a reverse piezoelectric phenomena. Therefore, in the case where a plurality of element units are simultaneously driven, the second side magnetic path 16 is brought into contact with the heel piece 10 and the yoke 13 and leak magnetic flux from other printing heads is conducted via the side magnetic path 16 without a permanent magnet 14. Besides, a coming round amount of magnetic flux to the magnetic path of other printing heads is decreased, and magnetic interference is reduced. Then, in the case where a simple element unit is driven, the side magnetic path 16 is released from the heel piece 10 and the yoke 13, and a magnetic flux of the permanent magnet 14 is prevented from leak to enable magnetic force to be utilized usefully as suction force of an armature 4.
