Piezoelectric actuator, method for manufacturing piezoelectric actuator, and liquid transporting apparatus

A piezoelectric actuator includes a supporting member in which pressure chambers are formed, a vibration plate which is joined to a joining section of the supporting member, a piezoelectric layer formed on the vibration plate, and an FPC provided on the piezoelectric layer. A contact section of an electrode formed on the piezoelectric layer and a terminal section of the FPC are electrically connected via a bump formed on the terminal section. A recess is formed on an upper surface of the supporting member right below the bump. While joining the piezoelectric layer and a wire member, any damage of the piezoelectric layer and any poor connection do not occur.

Electric connector of shielding cable, electric connector body and its manufacture

This invention can obtain a stable impedance characteristic by improving reliability of connection of a grounding terminal and an external conductor, to attain improvement in manufacturing and equalization of the impedance characteristic between products by entirely eliminating soldering process, to make thinning available, and to prevent that the grounding terminal and the external conductor cause poor connection by making secondary mold. It is the electric connector 100 used for connection of shield cables 200, which have signal wires 210 and grounding wires 220. The first housing 120 is primarily molded to the external conductor 110, and a support projection 113, which contacts the grounding terminal 140 by projecting to the inner side of the external conductor 110, is formed. At the position, which faces the support projection 113 through the grounding terminal 140 in the second housing 160 which is secondarily molded, a through hole 161, which is made of a core pin 341 that has carried out pressing of the grounding terminal 140 by projecting into the inner direction from a mold 310, is provided.

Laminated ceramic capacitor

Provided is a laminated ceramic capacitor in which internal electrodes (A1-D1, A2-D2) are buried in layers at intervals in the thickness direction of a ceramic main body (1). The lead-out electrodes (a1-d1, a2-d2) lead out to the side of the ceramic body (1) to constitute a lead-out portion. One end of the dummy electrodes (51-58) is led out to the side in the layer provided with the internal electrodes (A1-D1, A2-D2), and constitutes a lead-out portion. The lead-out portions of the extraction electrodes ( a1 to d1 , a2 to d2 ) of each layer overlap with the lead-out portions of the dummy electrodes ( 51 to 58 ) belonging to other layers in the thickness direction.

Hose clamp

The invention discloses a hose clamp. The hose clamp comprises a clamping belt (10) and a locking assembly (50) connected with the clamping belt (10). The locking assembly (50) comprises a lock body (51) and a locking piece (52) slidably connected with the lock body (51) in a matching mode. The clamping belt (10) comprises a movable end (12) penetrating into the lock body (51). The movable end (12) is provided with a plurality of closely arranged stopping parts (13). The locking piece (52) can selectively extend into or out of a groove (13a) formed between two adjacent stopping parts (13). After the locking piece (52) extends into the groove (13a), the movable end (12) can be prevented from moving reversely. According to the hose clamp, through the arrangement of the locking piece and thestopping parts matched with the locking piece, the situation that soft and hard pipes are poor in connection due to thread loosening after vibration or long-term use will not happen, and the reliability is high.

Circuit substrate and circuit substrate manufacturing method

A circuit substrate includes protruding terminals and has a structure that ensures an excellent connection with an electronic component, such as an IC. The circuit substrate on which an IC is to be mounted includes terminals that are to be electrically connected to solder bumps located on the IC. The terminals protrude from the mounting surface of a substrate body on which the IC is to be mounted. The sectional area of the top surface of each of the terminals is about 1.2 times the sectional area of each of the terminals on the mounting surface.
