发明内容
发明所要解决的课题
有关上述专利文献1的线性发电装置是如下的构造，即，由单燃烧室形缸构成的自由活塞发动机(流体压缸)的燃烧爆炸和线性发电机的作为电动机的功能的协作，使自由活塞发动机的活塞在轴线方向往复运动，将线性发电机的线圈作为电动机和发电机的原件共用，与控制它的控制装置一起，具有构造复杂，且成本高的问题。
另外，因为通过燃烧爆炸进行活塞向一方向的移动，通过电动机进行向另一方向的移动，所以，具有发电效率差的问题。
另外，因为是将自由活塞发动机和线性发电机串联连接的构造，所以形状长大，需要过大的占有空间。
为了解决课题的手段
本发明提供一种在构成流体压缸的活塞和缸之间引起发电的、消除了上述问题的线性发电装置。
概括地说，有关本发明的线性发电装置，具有交替地向缸内的活塞施加与缸的左端壁相接的左流体压室内的流体压和与缸的右端壁相接的右流体压室内的流体压而使该活塞在轴线方向往复移动的流体压缸构造，并做成下述结构，即，在上述活塞的与上述左流体压室相接的左受压面和与上述右流体压室相接的右受压面之间形成永久磁铁区域，同时，在上述缸的左右端壁间的筒壁上形成遍及上述左、右流体压室的发电线圈区域，通过具有上述永久磁铁区域的活塞在轴线方向的往复移动，引起上述发电线圈区域中的发电。
上述左、右流体压室构成燃烧室，并做成通过由该燃烧室中的燃料的燃烧爆炸产生的流体压在轴线方向移动上述活塞的结构。
或者，所述的线性发电装置是从外部交替地向上述左、右流体压室内供给高压流体，通过该高压流体的流体压在轴线方向移动上述活塞的结构。
将上述活塞做成筒形，由承受流体压的受压端板封闭了该筒形活塞的筒孔的两端开口面。
将由永久磁铁构成的多个环或多个短筒体叠层形成了上述筒形活塞。
发明的效果
根据本发明，能够将交替地施加缸两端的左、右流体压室的流体压而使活塞往复运动的流体压缸的构造作为基本构造采用，同时，在构成该流体压缸的活塞和缸之间引起发电，能够实现发电装置的构造的简单化和小型轻量化，能够稳定地得到效率好的发电。
另外，通过将活塞作为筒形，由受压端板承受流体压，得到活塞的移动的构造，能够实现该活塞的轻量化，引起圆滑的往复移动和效率好的发电。
进而，能够由上述受压端板有效地保护上述活塞的永久磁铁不受冲击、热的影响。

具体实施方式
为了实施发明的优选方式
下面，根据图1至图7，说明用于实施本发明的最佳方式。
有关本发明的线性发电装置具有交替地向缸1内的活塞(自由活塞)6施加与缸1的左端壁2相接的左流体压室4内的流体压和与缸1的右端壁3相接的右流体压室5内的流体压而使该活塞6在轴线方向往复移动的流体压缸构造。
上述缸1由左端和右端被端壁2、3封闭的正圆筒形的两端封闭形筒体构成，内部具有能够在轴线方向移动的活塞(自由活塞)6，在该缸1的左端筒壁和活塞6及左端壁2之间划分成上述左流体压室4，在该缸1的右端筒壁和活塞6及右端壁3之间划分成上述右流体压室5。
有关本发明的线性发电装置采用上述流体压缸构造，同时，具有如下的构造，即，在上述活塞6的与上述左流体压室4相接的左受压面7和与上述右流体压室5相接的右受压面8之间形成永久磁铁区域9，并且在上述缸1的左右端壁2、3间的筒壁上形成遍及上述左、右流体压室4、5的发电线圈区域11，通过具有上述永久磁铁区域9的活塞6在轴线方向的往复移动，引起上述发电线圈区域11中的发电。
上述左、右流体压室4、5构成燃烧室，并做成通过由该燃烧室中的燃料的燃烧爆炸产生的流体压在轴线方向移动上述活塞6的结构。
或者，做成从外部交替地向上述左、右流体压室4、5内供给高压流体20、20’，通过该高压流体20、20’的流体压在轴线方向移动上述活塞6的结构。
如图1、图2、图3所示，上述活塞6由永久磁铁筒体6’形成，并以如下的方式构成，即，由受压端板14封闭该永久磁铁筒体6’的筒孔13的两端开口面，由该受压端板14承受流体压。
作为具体例，图1是表示通过由单一的筒体6a构成的永久磁铁筒体6’来形成上述筒形活塞6的例子，将该永久磁铁筒体6’做成外插于筒形磁轭10，由受压端板14封闭两端开口面的活塞构造。
另外，图2是表示由将由永久磁铁构成的多个短筒体6c一体且同轴芯地叠层了的构造的永久磁铁筒体6’形成上述筒形活塞6的例子，将该永久磁铁筒体6’做成外插于筒形磁轭10，由受压端板14封闭两端开口面的活塞构造。

在将上述环6b、短筒体6c做成了叠层构造的情况下，通过环6b或短筒体6c的叠层数量的增减，能够增减活塞6(永久磁铁区域9)的长度。
最好是，将在图1至图4中说明的受压端板14通过由陶瓷板、纤维板、石材板、水泥板、碳板、金属板等构成的耐热板形成。

形成上述发电线圈区域11的发电线圈，包括按照上述各例示的极配置，由多个单位发电线圈组形成的情况。
当然，也可以以使形成永久磁铁筒体6’和永久磁铁柱体6”的所有的短筒体6c或环6b或短柱体6d在外周部成为同极，在内周部成为同极的方式做成叠层构造。
图5是表示采用由上述永久磁铁筒体6’(或永久磁铁柱体6”)构成活塞6的手段，同时在缸1中设置环状地包围发电线圈区域11的外周面的固定永久磁铁筒体1’，更有效地进行由发电线圈产生的发电的实施例。

作为例示，如图5所示，将多个永久磁铁环1a叠层，形成固定永久磁铁筒体1’，由该筒体1’环状地包围发电线圈区域11的发电线圈，而且经该发电线圈区域11环状地包围构成活塞6的永久磁铁筒体6’。
换言之，做成在发电线圈区域11的发电线圈的内周面和外周面配置永久磁铁筒体6’、1’，使发电线圈夹在了两永久磁铁筒体6’、1’间的构造。
构成上述固定永久磁铁筒体1’的永久磁铁环1a和构成上述活塞6的永久磁铁环6b，例如如图3、图5所示，以邻接的环1a、6b成为相反极性的方式分别叠层。
在图2所示的由短筒体6c形成了永久磁铁筒体6’(活塞6)的情况下，也可以采用以如下的方式配置的结构：将多个永久磁铁短筒体叠层形成固定永久磁铁筒体1’，由该筒体1’环状地包围构成活塞6的永久磁铁筒体6’，例如使筒体1’和6’中的邻接的短筒体成为相反极性。
在图1至图4的各例示中，可以设置包围上述发电线圈区域11的固定永久磁铁筒体1’，在设置了该固定永久磁铁筒体1’的情况下，可以将构成活塞6的永久磁铁筒体6’做成薄壁，同样，将活塞永久磁铁柱体6”做成小直径，谋求进一步的活塞6的轻量化。
如上所述，在上述左、右流体压室4、5构成燃烧室的情况下，例如在左右端壁2、3上设置火花塞19，在该左右端壁2、3或缸1的左右端筒壁上设置燃料喷射阀17，例如在左右端壁2、3或左右端筒壁或缸筒壁的中间部上设置排气阀18。
下面，根据图6A至图6D，说明左右流体压室4、5构成左右燃烧室的情况下的动作。
如图6A、图6B所示，通过由左侧的火花塞19使通过同燃料喷射阀17供给的左燃烧室4内的压缩燃料燃烧爆炸，对受压端板14的左受压面7赋予流体压，在轴线上向右方移动活塞6(永久磁铁筒体6’或永久磁铁柱体6”)。
如上述图6C、图6D所示，通过活塞6的上述向右方移动，将通过右侧的燃料喷射阀17喷射到右燃烧室5内的燃料(与气体的混合气)压缩，由右火花塞19点火，在右燃烧室5内使压缩燃料燃烧爆炸，对受压端板14的右受压面8赋予流体压，在轴线上向左方移动活塞6(永久磁铁筒体6’或永久磁铁柱体6”)。
由上述左右燃烧室4、5内的燃烧爆炸产生的流体(燃烧气体)20，伴随着活塞6的往复移动，通过排气阀18排出。
通过反复进行上述动作，形成上述活塞6的永久磁铁筒体6’或永久磁铁柱体6”(永久磁铁区域9)反复进行往复移动，引起发电线圈区域11中的发电。
接着，基于图7A、图7B，说明从外部向上述左、右流体压室4、5供给高压流体，使活塞6往复运动的实施例。这里，所述的高压流体20’，除了空气、蒸气以外，还可以使用各种瓦斯气体。
例如，在左右端壁2、3上设置流体供给阀21和排气阀22，如图7A所示，通过左流体供给阀21向左流体压室4内供给高压流体20’，对受压端板14的左受压面7赋予该高压流体20’的流体压，在轴线上向右方移动活塞6(永久磁铁筒体6’或永久磁铁柱体6”)。
接着，如上述图7B所示，在活塞6到达了上述右方移动的终端时，通过右流体供给阀21向右流体压室5内供给高压流体20’，对受压端板14的右受压面8赋予该高压流体20’的流体压，在轴线上向左方移动活塞6(永久磁铁筒体6’或永久磁铁柱体6”)。
通过反复进行上述的动作，形成上述活塞6的永久磁铁筒体6’或永久磁铁柱体6”(永久磁铁区域9)反复进行往复移动，引起发电线圈区域11中的发电。
