摘要:
A drive device using an electromechanical transducer having inconsiderable loss of drive energy and excellent drive efficiency even with variation in load in which an elastic member is arranged between a driven member frictionally coupled to a drive member and a frictional member fitted to an opening of the driven member whereby drive force is transmitted from the drive member to the driven member with no loss of energy, a frictional force between the drive member and the driven member is periodically changed, an average frictional force is increased when a shift between a phase of variation in a drive velocity and a phase of variation in the frictional force is null, when the shift between the phases is 180.degree., the average frictional force is adjusted to decrease whereby the drive efficiency can be promoted, and when the device is stopped, the drive device can be protected against unintentional external force bringing the drive member and the driven member into fixing contact with each other by an electromechanical transducer.

An actuator using an electromechanical transducer capable of maintaining stable driving function even under a severe environment of high temperature and/or high humidity, or the like, and an apparatus mounted with the actuator. The actuator are disclosed is constituted to move a slider block frictionally coupled to a drive shaft in a predetermined direction by reciprocating oscillation having different speeds of the drive shaft driven by elongation and contraction displacements of a piezoelectric element and the piezoelectric element, a portion where the piezoelectric element is coupled to the drive shaft and a portion where the piezoelectric element is coupled to a frame is sealed by silicone resin, fluorinated resin or the like to thereby protect them from the high temperature and/or high humidity environment.
摘要:
A driving apparatus having an electromechanical transducer which extends and contracts; a first member connected to one end of the electromechanical transducer; a driving frictional member which is formed of a ceramic material and is connected to the other end of the electromechanical transducer; and a second member frictionally coupled with the driving frictional member, whereby either one of the first or second object is fixed and the electromechanical transducer is made to extend and contract, thereby driving in a specified direction the member which is either the first or second member and is not fixed.

The running stabilizing linkage system of the invention, which is applicable to the joints of a 3-coach articulate car essentially consisting of a front coach, a rear coach and an intermediate coach which is comparatively short, comprises a link holder 2 disposed rotatably about a vertical axis in the center in plan view of the intermediate coach, a pair of connecting rods 4, 4 each connected to the link holder through a bearing 7, with the connecting rods being supported rotatably about vertical axes in positions radially equi-spaced from the center of the link holder, and a pair of link brackets 3, 3 each disposed in the transverse center of the end of the front or near coach which is closer to the intermediate coach, with the other end of each connecting rod being connected rotatably about a vertical axis to the corresponding link bracket 3 through a bearing 8. This linkage prevents jolt of the car, particularly pitching of the intermediate coach.

An object is to provide a battery pack which can restrict movements of battery a module and a spacer even after use for a long period. A battery pack 100 comprises a plurality of battery modules 110, a plurality of holding spacers 130 each being placed in a space between the battery modules, and a first and second spacer support members 160, 170 which hold the holding spacers 130 in a vertical direction Z. Each holding spacer 130 includes a plurality of first elastic members 143 and a plurality of second elastic members 145 which protrude in the vertical direction Z. The holding spacer 130 is elastically held between the first and second spacer support members 160, 170 while the first and second elastic members 143, 145 are elastically deformed into elastic pressure contact with the first and second spacer support members 160, 170.

The object is to enable the user to selectively set the notification of a gamut error and notification deactivation condition. For this, a detection unit 3 detecting a gamut error of an input image signal, and a plurality of notifying units 5, 8 and 6, 9 and 11 notifying that a gamut error has occurred in different methods from each other are provided. And, a setting unit 15 carrying out the operation of setting which of these notifying units is to be caused to carry out notification and the operation of setting the condition for deactivating notification of a gamut error is provided. The information indicating the setting result by the setting unit 15 is stored in a storage unit 14. Further, under control of a control unit 13, based on that a gamut error has been detected by the detection unit 3, the notifying units indicated by the information acquired from the storage unit 14 is caused to carry out notification of a gamut error and deactivation of notification of a gamut error under the condition indicated by the information.
