  • Patent number: 11967294
    Abstract: A common electrode driver includes an inverting amplifier including a first resistor, a second resistor, and an operational amplifier, and a resistance ratio adjustment circuit that adjusts, in accordance with a length of one horizontal scan period, a resistance ratio being a ratio of a resistance value of the second resistor to a resistance value of the first resistor. A feedback voltage is provided to one end of the first resistor. The resistance ratio adjustment circuit sets the resistance ratio when second driving is performed, in which a length of one horizontal scan period is a second time longer than a first time, to be smaller than the resistance ratio when first driving is performed, in which a length of one horizontal scan period is the first time.

  • Publication number: 20020079678
    Abstract: An air bag device having a switch adapted to be operated when a breakable cover member covering an air bag module mounted in the steering wheel is pushed. Particularly, H-shaped tear lines, including grooves of a V-shape in section, are defined in an inner surface of the cover member. The tear lines are broken by a pressure resulting from the expansion of the air bag to open a lid defined in the cover member. A pair of ridges are integrally formed on the cover member astride a central one of the tear lines. The rigidity of the rear cover member is enhanced by the ridges, whereby the deformation of the cover member is prevented. Thus, the cover member can be slid smoothly to ensure the reliable operation of the switch.
