摘要:
A magnetic recording/reproducing apparatus for reproducing data recorded on a recording medium based on the signal read by a head contains a filter circuit which restricts the frequency range of the read signal and allows the low frequency read signal to pass through it, a full wave rectification circuit for full wave rectification of the read signal output from this filter circuit and an integrating circuit for generating a threshold signal of the read signal output from the filter circuit based on the integrated value obtained by integrating the output signal from the full wave rectification circuit when reproducing data and for holding the integrated value at the time of the immediately before data reproduction during the operation other than the data reproducing operation. Further, the apparatus contains a binarization circuit for generating read data pulses based on the threshold signal output from the integrating circuit and a differentiated signal obtained by differentiating the read signal output from the filter circuit.

The present invention provides a search and rescue radar transponder easy in maintenance and checking. In the search and rescue radar transponder of the invention, the transmission electric power of the transmitting circuit 3 leaked at the changeover switch 7 is inputted to the receiving circuit 2, and whether the search and rescue radar transponder operates normally or not is judged by comparing the leaked electric power level detected by the receiving circuit 2 with a prescribed level at the controlling circuit 4. Hereby, the operation-checking of the search and rescue radar transponder proper other than an antenna can be executed by a built-in apparatus, and its maintenance and checking can be executed easily and rapidly.

A phased-array antenna is provided with a dummy antenna element and a dummy transmit/receive module for testing the other transmit/receive modules by transmitting test signals to, or receiving test signals from, the other antenna elements in the array. Test signals are transmitted in a test mode that alternates with normal-mode operation. Receive power level and/or phase can be checked. The transmit/receive modules in the array are simplified in structure and improved in reliability due to the elimination of special receive check circuits. Antenna accuracy can also be improved by adjusting the phase shifters in the transmit/receive modules to compensate for variations in transmission phase.

A magnetic recording/reproduction apparatus of the invention has a magnetic head for reading a vertical magnetically recorded signal, an inplane magnetic recorded signal or a magnetic recorded signal having both a vertical magnetic component and an inplane magnetic component and for supplying a reproduced signal, a first analog signal converting circuit for converting the reproduced signal into an analog inplane reproduced signal when the reproduced signal is a vertical reproduced analog signal, a second analog signal converting circuit for bypassing an inplane analog reproduced signal when the reproduced signal is the inplane reproduced analog signal, and a third analog signal converting circuit for converting the reproduced signal into an inplane reproduced analog signal when the reproduced signal is the inplane reproduced analog signal. The circuits are switched to operate selectively in accordance with the type of signals reproduced from a magnetic recording medium.

An image forming apparatus includes a body, a toner container that is removably set in the body and contains toner, a toner supplier to supply the toner from the toner container to the body, a memory that stores container information that is information of the toner container, and circuitry. The circuitry is to determine, after the toner container is set in the body, based on the container information acquired from the memory, whether the toner container set in the body is same as a toner container set in the body in a past and the container information satisfies a predetermined condition, and to drive the toner supplier in a case where the toner container set in the body is determined to be same as the toner container set in the body in the past and the container information satisfies the predetermined condition.

A method for monitoring a mounting tact of a component mounting apparatus including a component supplier for supplying a component and a component holder for holding the component from the component supplying device and mounting the component onto a circuit board. The method includes collecting and monitoring a mounting tact result value of the component mounting apparatus during a mounting operation via a communication system. The method further includes calculating a tact loss corresponding to an amount by which the mounting tact result value is greater than a standard mounting tact and monitoring the calculated tact loss.
