Abstract
Description
また、特許文献1に示すように、ユーザーの腕の動きなどを捉えて運動エネルギを電気エネルギの変換する電磁誘導型発電器付の電子時計でも、非携帯状態にある場合には蓄電池(2次電池)の消費電力を低減させるべく、自動的に節電状態になるパワーセーブ機能を有している。
図3は、本発明の第1実施形態を示す図2のA-A線に関する模式的断面図である。図4は、本発明の第1実施形態の地板の平面図である。図5は、本発明の第1実施形態の内部構造を示す概要である。図6は、本発明の第1実施形態を説明するための部分的斜視図である。図7は、本発明の第1実施形態の対向電極2と帯電膜3のパターンを示す図である。図8は、本発明の第1実施形態の対向電極2と帯電膜3の別のパターンを示す図である。図3の断面図において、風防(glass)24側を上部、上側、上方といい、裏蓋(case back)42側を下部、下側、下方と称す。
本実施形態は、腕時計など携帯用電子時計に適用した場合の実施形態である。携帯用電子時計は、風防24を含む外装ケーシング41、42(裏蓋42)と、文字板25と、ハウジング33、34と、このハウジング内に配置されたクオーツムーブメント200と、ハウジング内に配置された静電誘導発電器とを有している。風防24は、パッキン43を介して外装ケーシング41に嵌めこまれている。風防24は、ミネラルガラスに限らずプラスチックなどの一般的な透明材料で形成されている。
軸8には回転部材4が固定されており、回転部材4の下面には帯電膜3が配置されている。一方、帯電膜3に対向するように、上部表面に対向電極2が配置された対向基板1が、地板33に設置固定されている。クオーツムーブメント200の回路基板5も、対向基板と同様に地板33に設置固定されている。
ここでは、対向基板1と帯電膜3とのギャップを精密に管理するため、対向基板1と回路基板5を別体で作製しているが、同様の位置精度が満たされるなら回路基板5と対向基板1を同一の基板に形成することも可能である。回路基板5と対向基板1とが別基板の場合は接続コネクタ、導通バネ、接続端子などで導通を行う。これらは、後述の実施形態においても同様である。
本発明で帯電膜として用いられるエレクトレット材料には、帯電しやすい材料を用い、例えばマイナスに帯電する材料としてはシリコン酸化物(SiO2)や、フッ素樹脂材料などを用いる。具体的には一例としてマイナスに帯電する材料として旭硝子製のフッ素樹脂材料であるCYTOP(登録商標、Amorphous Fluoropolymer)などがある。
帯電膜3(エレクトレット膜)の内面には、負電荷が保持されているので、対向電極2には、静電誘導により正電荷が引き寄せられる。対向基板1に設けられた対向電極2、回転部材4の下面に設けられた帯電膜3は、図7に示すようなパターンであって、中心から等しい角度の放射部2’、3’が等間隔で形成されている。図7のパターンでは、図6の斜視図にみられるように、放射部3’、3’相互間はそれぞれブランク部(透し孔)となっており、放射部2’、2’相互間には電極が設けられておらず、対向基板1が露出しているか、対向基板1をブランク部にしても良い。なお、放射部3’、3’相互間はブランクでなく、透過性の部材で構成しても良く、その場合には前記透明性部材の窓部側に、回転を目立たせる印刷や凹凸などを設けることで、時計上面から窓部51と52を通して回転部材4が回転している様子を認識しやすくなる。もちろん、前記印刷や凹凸は、放射部3’の窓部側に施されていても良い。
詳しい時計製作工程は後述するが、本実施形態では、軸8、回転部材4、対向電極2を時計に組み込む際に位置合わせが必要であり、特に帯電膜3と対向電極2とのギャップは発電特性にかかわるため微調整が必要となる。したがって、第1パターンにおいて、回転部材4の放射部3’、3’相互間と、対向基板1の放射部2’、2’相互間に位置する部位を、ブランクかあるいは透明部材にした場合には、時計の裏ブタ42側、あるいは、時計の風防側24から、相互の位置と状態を目視しながらの調整が可能となる。これにより調整工程を簡易化できる。この調整作業においては、すべての放射部3’、3’相互間と、対向基板1の放射部2’、2’相互間に位置する部位とを、ブランクか透明部材で構成する必要は無く、それぞれ一部に相互の位置を確認できるブランクか透明部材による窓を設けるだけでも良い。
本発明の第2実施形態は、図3の第1実施形態における回転部材4の下面に、帯電膜3の代わりに対向電極2、対向基板1の上面に、対向電極2の代わりに帯電膜3が設置されたものであり、その他の構成は第1実施形態と同様である。したがって、本実施形態では、上部から下部に向かって、文字板25の窓部51、地板33の窓部52、回転部材4、対向電極2、帯電膜3、対向基板1、受け板34の順序で配置されている。対向電極2、帯電膜3のパターンは、図7の第1パターンを採用しており、対向電極2は回転部材4が固定された軸8から出力端子を取出し、静止している対向基板1の上面に設置された帯電膜3からも出力端子を取り出している。
図10は、本発明の第3実施形態を示す模式的断面図である。
(a)地板33に、対向電極2が設置された対向基板1を組み込む。
(b)クオーツムーブメント(歯車駆動部21、回路基板5など)を組み込み、回路基板5と対向基板1との導通をとる。
(c)回転部材4を上方に寄せる(押圧)ためのバネ7を設置する。
(e)回転錘10と歯車15が軸9に固定されて、軸9が受け板34にベアリングで支持されて一体化している。受け板34には、回転部材4が取り付けられた軸8を軸支する軸受け50を設けられている。歯車15を軸8に固定された歯車14にかみ合わせつつ、軸受50の高さ調整により、回転部材の帯電膜3と対向基板の対向電極2とのギャップ調整を行なう。このとき、作業確認窓53より、目視しながらギャップ調整を行うことができる。帯電膜3と対向基板1が接触すると電荷が逃げてしまい帯電量が減るので、接触しないように留意しなければならない。
(f)回転錘を取り付ける。
(g)地板33に2次電池22を載置する。
本発明の第4実施形態は、図10の第3実施形態における対向基板1の下面に、対向電極2の代わりに帯電膜3、回転部材4の上面に、帯電膜3の代わりに対向電極2が設置されたものである。したがって、本実施形態では、上部から下部に向かって、文字板25の窓部51、地板33の窓部52、対向基板1、帯電膜3、対向電極2、回転部材4、受け板34の順序で配置されている。
図13は、本発明の第5実施形態の一例を示す模式的断面図である。図14は、本発明の第5実施形態のソーラーセル(a)~(c)を示す模式的平面図である。
第1実施形態を用いた場合には、対向電極2、対向基板1を第3実施形態と同様に透過性の基板、電極を用いれば、これらの下にソーラーセル6を設置することができるので、第5実施形態が、実現可能である。また、第2実施形態を用いた場合、回転部材のブランク部を透過性の部材、穴などにし、対向基板1上の帯電膜3に遮光塗料を塗布し、放射状の非帯電膜部分を、透過性の部材、ブランク部などにすれば、第5実施形態が可能となる。第5実施形態は、後述する実施形態においても同様に適用することが可能である。
図15は、本発明の第6実施形態の一例を示す模式的断面図である。
また、図15では、第3実施形態を用いて第6実施形態を説明しているが、これに限定されるものではなく、本明細書に記載の各実施形態に適用可能である。ソーラーセル6’のリング状のソーラーセル6’を、回路基板5などのICに外光が当たらないように、遮光壁の役割を持たせるように配置するとより効果的である。
