An oscillation type inertia force sensor includes an oscillator, an oscillation circuit unit, and a detection circuit unit. The oscillation circuit unit functions as a self oscillation circuit of a closed loop with the oscillator as a resonant element, and includes an AGC circuit. The AGC circuit includes a VGA circuit, a comparison circuit comparing a predetermined reference voltage with a voltage of the monitor signal to output a control signal based on the compared result, and a pulse width modulation circuit modulating the control signal to a pulse width modulation signal. Based on the pulse width modulation signal, the driving signal is modulated with the output of the VGA circuit switched between an ON state and OFF state to control the degree of the amplification factor of the VGA circuit.

A rear suspension system for motor vehicles. Both leg ends of a gate-shaped swing arm which at its free end supports the central part of a rear axle are pivotably secured to a vehicle body frame, a tension rod is provided between the lower end of a downwardly extending swing link mounted near the free end of the swing arm and a portion of the vehicle body frame near and below the above pivoted point of the swing arm, and one end of a damper disposed between both legs of the swing arm in a position above the tension rod is mounted near and above the pivoted point of the swing arm, while the other end thereof is attached to the swing link. The rear suspension system can be mounted in a relatively narrow space, and even with devices of relatively large capacities mounted thereabout, it can exhibit its damping characteristics satisfactorily.

An inertia force sensor that shortens a time from power activation until inertia force can be detected includes an oscillator, an oscillation circuit unit, and a detection circuit unit. The oscillation circuit unit functions as a closed loop self oscillation circuit with the oscillator as a resonant element, and includes a CV conversion circuit converting a monitor signal based on electrostatic capacitance according to an oscillating state of oscillator into a monitor signal based on a voltage corresponding to an amount in change of the electrostatic capacitance, and an automatic gain control circuit controlling gain based on the monitor signal converted at the CV conversion circuit to generate a driving signal, and supplying the driving signal to the oscillator. The CV conversion circuit includes an amplifier that amplifies a monitor signal with an amplification factor for a predetermined period after power activation.

A web-mail system receives from a web server mail IDs assigned to clearly distinguish one e-mail from another among all the e-mails stored in a mail box, and transmits the mail IDs determined according to a scroll position in a list window to the web server, making a request for list information of those mail IDs. The web-mail system receives the requested list information from the web server and stores the list information in a list information storage unit. The web-mail system creates a list to be displayed in a list the list window based on the list information stored in the list information storage unit.

An external-force detecting apparatus includes at least one drive line connecting the corresponding drive electrodes to a driving unit and at least one monitor line connecting the corresponding monitor electrodes to the driving unit. The driving unit outputs a drive signal to the at least one of the drive electrodes through the at least one of the drive lines to drive an oscillator and performs automatic gain control to the level of the drive signal based on the oscillation state of the oscillator acquired from the at least one of the monitor electrodes through the at least one of the monitor lines. The external-force detecting apparatus further includes a switching circuit arranged to switch between connection and disconnection of an electric path between the oscillator and the driving unit via at least one of the drive lines or the multiple monitor lines.
