摘要： A connector includes a housing and a plurality of contacts, and the bottom portion of the housing has a holding bar for holding the contacts. In a region of the bottom portion of the housing corresponding to tips of all the contacts extending from the holding bar upwardly and toward the interior of the housing, a rectangular recess is provided, and a contact buckling-preventing plate is provided in the recess, which includes an upper surface portion formed with through-holes at locations corresponding to contact portions of the contacts, partition walls forming defined spaces for accommodating the contacts in cooperation with the upper surface portion, and jointing ends to be connected to both lateral inner ends of the recess on the side of the holding bar to permit a pivotal movement of the plate. In this manner, the connector can realize an even more reduced overall height and prevent the buckling of contacts upon extraordinary insertion and removal of a card-shaped connecting object.

摘要： A tuned oscillator utilizing a thin film ferromagnetic resonator is disclosed. The oscillator comprises an active element for oscillator and a YIG thin film resonator connected to the active element as a part of feed-back circuit for the active element. The YIG thin film resonator is applied with a bias magnetic field perpendicular to a surfce of a YIG disk which is generated by a permanent magnet for a fixed component and a coil for a variable component for the resonance frequency. The resonance frequency is stabilized by use of a PLL circuit connected to an output of the oscillator and feeding back to the coil. Since the YIG thin film tuned oscillator has a high Q value, high quality communication signal processing can be achieved. The YIG tuned oscillator is used as local oscillator for a transciever.

摘要： In a thin film ferromagnetic resonance tuned filter is disclosed which comprises a ferrimagnetic thin films, input and output signal transmission lines respectively coupled with the ferrimagnetic thin films, and a magnetic circuit for applying a DC magnetic field to the ferrimagnetic thin films, the present invention expands the variable frequency band by forming extensions each extending from the signal transmission line so that the distance from the coupling point of the signal transmission line coupled with the corresponding ferrimagnetic thin film to the grounded end thereof is 1/10 or above and less than 1/4 the wavelength of a wave transmitted in the transmission lines at the upper limit frequency of a tuning frequency band. Further the deterioration of the isolation characteristics is suppressed by bending the extended portions not to form parallel portions to another transmission line.

摘要： An electrical connector includes a connector body to be mounted on a circuit board of an electrical appliance by means of protruding terminal legs of contacts incorporated in the connector body and by means of fixing legs of a shell as a worked body of a metallic plate forming an outer casing of the connector body. A mating connector socket of the shell is positioned so as to open outwardly of the electrical appliance. The shell has an auxiliary leg to be fixed to the circuit board. The auxiliary leg is formed by extension pieces extending from part of the shell on the side of the mating connector socket with respect to the fixing legs of the shell. The auxiliary leg serves to mount the electrical connector on the circuit board with great stability which is maintained for a long time.
