摘要： To provide a zoom lens system with a vibration reduction having a long back focal length suitable for a digital SLR camera, a high zoom ratio, and a wide angle of view of 70° or more. The system includes, in order from the object, a first positive lens group, a second negative lens group, a third positive lens group, and a fourth positive lens group. Upon zooming from wide-angle end state to telephoto end state, a distance between the first and second lens groups increases, a distance between the second and third lens groups decreases, and a distance between the third and fourth lens groups varies. The third lens group is composed of a positive front lens group and a negative rear lens group. Image plane correction upon camera shake can be performed by shifting only the rear lens group substantially perpendicularly to the optical axis. Given conditions are satisfied.

摘要： A piezoelectric/electrostrictive device includes a pair of thin plates confronting each other, a fixing member supporting the thin plates thereon, and movable portions disposed on end portions of the pair of thin plates. Protrusions are formed on principal surfaces of first ceramic green sheets according to at least a single thick film forming process. The protrusions will subsequently serve as the movable portions, and the first ceramic green sheets will subsequently serve as the thin plates. The first ceramic green sheets and a second ceramic green sheet which will subsequently serve as the fixing member are stacked into a ceramic green laminated body. The ceramic green laminated body is baked into an integral ceramic laminated body. Piezoelectric/electrostrictive elements are formed on the ceramic laminated body. After the piezoelectric/electrostrictive elements are baked, unnecessary portions are removed from the piezoelectric/electrostrictive elements to fabricate the piezoelectric/electrostrictive device.
摘要翻译：压电/电致伸缩器件包括彼此面对的一对薄板，支撑其上的薄板的固定部件和设置在该对薄板的端部上的可动部分。根据至少一个厚膜形成方法，在第一陶瓷生片的主表面上形成突起。这些突起随后将用作可动部分，并且第一陶瓷生片将随后用作薄板。第一陶瓷生片和随后用作定影构件的第二陶瓷生片堆叠成陶瓷绿色层压体。陶瓷绿色层压体被烘烤成一体的陶瓷层压体。在陶瓷层叠体上形成压电/电致伸缩元件。在压电/电致伸缩元件被烘烤之后，不必要的部分从压电/电致伸缩元件去除以制造压电/电致伸缩器件。

摘要： In a snow-removing machine, an expandable and contractible regulating mechanism is coupled between a steering handlebar of a machine body including a snow-removing section and a drive section capable of being turned relative to the machine body about a wheel driving shaft, and is capable of regulating the level of the snow-removing section relative to the drive section. The expandable and contractible regulating mechanism is comprised of a cylinder connected to the machine body, a piston which divides the inside of the cylinder into a first chamber and a second chamber, a piston rod coupled to the piston and connected to the drive section, a communication passage permitting communication between the first and second chambers, and an on-off valve for opening and closing the communication passage. A high-pressure gas is filled in the first and second chambers, so that the expansion and compression of the high-pressure gas is permitted upon closing of the on-off valve. Thus, during a snow-removing operation of the snow-removing machine, vibration applied to the drive section can be absorbed utilizing the expandable and contractible regulating mechanism for regulating the level of the snow-removing section.
摘要翻译：在除雪机中，可膨胀和收缩的调节机构联接在包括除雪部分的机体的转向车把与能够围绕车轮驱动轴相对于机体转动的驱动部分之间，并且是能够调节除雪部相对于驱动部的高度。可膨胀和可收缩的调节机构包括连接到机体的气缸，将气缸内部分成第一室和第二室的活塞，联接到活塞并连接到驱动部的活塞杆，连通通道，允许第一和第二室之间的连通，以及用于打开和关闭连通通道的开关阀。高压气体被填充在第一和第二室中，使得在关闭开关阀时允许高压气体的膨胀和压缩。因此，在除雪机的除雪作业中，利用用于调节除雪部的水平的可膨胀收缩调节机构，能够吸收施加于驱动部的振动。
