Title:
双安定バルブの受動的にアドレス可能な行及び列アレイ、紙ハンドリングシステム及び常閉双安定バルブ
Document Type and Number:
Japanese Patent JP4065043
Kind Code:
B2
Abstract:
A bistable valve (10,30) useful for paper handling applications is disclosed. The valve (10,30) can be batch fabricated in two dimensional valve arrays, with each valve in the array being controlled by passive matrix addressing. Typically, each valve (10,30) includes a valve housing (12,32), an electrically conductive movable element (13,33) such as cantilever beam, diaphragm or film. Valve action is provided by use of housing embedded switching electrodes (17,19) for moving the movable element (13,33) between an aperture blocking position and an aperture open position. To reduce unswitched movement when the switching electrode bias is reduced or not present, electrostatic or mechanical catches can be used.
