摘要:
The present invention provides a cooling apparatus which is easy to build and to fix it to electronic devices, superior in thermal conduction and heat dissipation, and possible to make thin the total configuration of the apparatus. The liquid cooling unit 9 and the air cooling unit 12 are formed in a unit. A heat absorption surface 19 of the liquid cooling unit 9 is contacted or bonded to the heat generation component such as the CPU and the heat generator, which have the largest power consumption and also locally generate heat within a small area in the box 2. In the liquid cooling unit 9, a liquid cooling pump 14 composed of an electromagnetic pump is arranged for circulating the coolant in the flow path 10. The heat generated by the heat generation components such as CPU 6, heat generator 7, and the like is thermally diffused with heat conduction into the whole liquid cooling unit 9 by circulating the coolant with the liquid cooling pump 14.
摘要:
A connector housing has a lock arm for locking a terminal therein. The lock arm deflects in an complete insertion state of the terminal so that a spacer abuts against a side surface of the lock arm. The lock arm is formed with a projection which abuts the incompletely inserted terminal in the spacer advancing direction. The projection may be a plate piece elongated in the longitudinal direction of the lock to be pinched by a pair of a resilient contact plates of the terminal. Alternatively, the lock arm may have a protrusion engaging with an engagement hole formed in the connector housing. The protrusion is a rectangular plate extending from the fore end of the lock arm. An inclined guide surface continuous with the engagement hole may be provided in the connector housing. Alternatively, the connector housing may have an inner embossed wall positioned closely to the deflected lock arm to oppose to the spacer. A clearance between the embossed wall and the lock arm is determined within the elastic deflection limit of the lock arm.

A double lock connector 1 having spacers 3,4 for engaging terminals is provided with detecting pin inserting portions 16,17 continuing from the front end of a connector housing 2 to the spacers 3,4. The detecting pin inserting portions are of slits. The detecting pin inserting portions 16,17 communicate with respective accommodating recesses 13,14 for base plate portions 9,10 of the spacers 3,4. Detecting pins are arranged opposite to the front end of the connector housing 2, and the detecting pins are inserted into the detecting pin inserting portions and abut against the respective spacers 3,4. The detecting pins are set inside a continuity testing portion of a terminal continuity testing member, and the continuity testing portion is moved toward the front end of the double lock connector 1. Thus, the presence of the spacers is securely detected.

摘要:
A piezoelectric actuator 60 includes a piezoelectric element 10 expanding and contracting according to a state of an electric field, a pedestal 20, a vibration film 30, and a support member. In the vibration mode of the divided vibration occurring in the piezoelectric actuator in a high frequency band, one or more reinforcement members 50 are selectively disposed on an upper surface or a lower surface of the piezoelectric element 10, in a region where a node of divided vibration occurs. With such configurations, the vibration mode can be changed in the piezoelectric element 10. Therefore, in the frequency sound pressure level characteristics, the divided vibration causing hills or valleys (peaks or dips) can be effectively suppressed, thus enabling the achievement of flatness of frequency sound pressure level characteristics and of reproduction of excellent sound.
