Title: Method for regulating capacitor capacitance
Inventor: IIZUKA HIROYUKI
IPC: H01G4/255
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To regulate a small and low-cost capacitor to a desired capacitor capacitance by a method wherein a voltage which exceeds a rated voltage is applied to a ceramic capacitor which is made of a ferroelectric ceramic and the capacitance of the ceramic capacitor is regulated. SOLUTION: A ceramic capacitor 10 is formed of a ferroelectric ceramic 11 and of an electrode 12 and an electrode 13 which sandwich the ceramic, and a PZT-based material is used as a material for the ferroelectric ceramic 11. A voltage is applied, by a voltage generation device 14, across both electrodes 12, 13 at the ceramic capacitor 10, the permittivity of the ferroelectric ceramic 11 is changed, and a capacitor capacitance is changed. When the applied voltage is at Em or -Em, the capacitor capacitance becomes a maximum value, and, when it is at Ec or -Ec, the capacitor capacitance becomes a minimum value. Consequently, when the height and the direction of the applied voltage are regulated, the capacitor capacitance can be regulated between the maximum value and the minimum value.

Title: Method of operating vehicle occupant protecting device
Inventor: MASHIYUU FUANGU
IPC: B60R21/16
Filed: 1995-02-07
Abstract: PURPOSE: To provide a method that activates impact-responsive devices in vehicles within a desired time limit in case of an impact event in need of device activation by discriminating between impact events in need and in no need of device activation. CONSTITUTION: A single-point sensing device senses the deceleration of a vehicle during an impact event. The sensed deceleration is integrated into the vehicle velocity. The velocity is then integrated into the vehicle displacement. The difference between the deceleration and a preselected deceleration bias is integrated into a residual energy density. The residual density is compared to a threshold residual energy density from an activation threshold line predefined on the basis of the impact characteristics of the vehicle. A residual energy density equal to or greater than the activation threshold line activates an impact-responsive device.
