To provide a shape memory alloy actuator using a shape memory alloy that mechanically restrains a moving body in position to prevent oscillation, the actuator has a moving body pushing member adapted to be capable of abutting to the moving body, a bias spring for the moving body pushing member that exerts an external force on the moving body pushing member in the direction opposite to the direction of change in the shape of a shape memory wire caused by heating, a bias spring for the moving body that exerts an external force on the moving body in the direction same as the direction of change, a first stopper that restricts the movement of the moving body to a predetermined position upon cooling. One end of the shape memory wire is fixed, the other end is mechanically linked with the moving body pushing member. The moving body pushing member and the moving body are moved by deformation caused by heating, and the moving body and the moving body pushing member are separated, when the moving body is stopped at the position of the first stopper.

In a drive mechanism which displaces a movable lens to be displaced, a shape memory element which is displaced due to heating. A displaceable range of a movable lens is restricted between a first position and a second position. With the shape memory element in a heated state upon applying a predetermined amount of heat to the shape memory element, the movable lens is displaced to the first position, and when the shape memory element is not heated, the movable lens is displaced to the second position. During a normal observation, a time for which the movable lens is displaced to the second position is longer than a time for which the movable lens is displaced to the first position.

A shutter device includes a stationary plate having a plurality of driving electrodes movable element opposes the stationary plate and including a sheet subjected to an electret-forming process. A drive control unit for moving the movable element using variation in electrostatic force, thereby shielding light. The electrostatic force is generated between constant charges held in the movable element as a result of the electret-forming process, and charges generated in each of the driving electrodes when a voltage is applied to each driving electrode. The generated electrostatic force is varied by varying the voltage applied to each driving electrode.

A sheet binding processing apparatus includes a conveying portion, a conveying path for sheets, a stacking portion on which sheets from the conveying path are stacked, a first regulating portion for regulating a sheet bundle on the stacking portion in a crossing direction, a second regulating portion for regulating a sheet bundle in the conveying direction, a manual setting portion for setting sheets from an outside of the apparatus, and a binding device which binds a sheet bundle by a staple and moves in the crossing direction. An angular posture of the binding device located at a third position is different from an angular posture located at a first position. An angular posture of the binding device located at the third position is different from an angular posture located at a second position. The second position is located at a second side of the first position.

To provide an image forming apparatus having a sheet processing apparatus installed in an in-body space, capable of discharging sheets of different sizes without interfering with discharge operation of the sheet processing apparatus in a compact configuration. An image forming apparatus has a sheet binding unit disposed in an in-body space part thereof, a first conveying path for conveying the sheet discharged to the in-body space part toward the sheet binding unit, and a second conveying path for conveying the sheet discharged to the in-body space part toward a second stack tray that stacks thereon the sheet vertically below a first stack tray disposed outside the in-body space part. The second conveying path extends, inside the in-body space part, substantially horizontally between an image forming part and the sheet binding unit.

To facilitate permeation of water when water is applied to the crimping range of a sheet made of a water-permeable paper material. A binding unit applies water to placed sheets and then crimp-binds the sheets. The binding unit includes a pair of pressure teeth (pressure teeth and receiving teeth part) provided on both the front and back sides of the sheets and configured to crimp-binding the sheets, a water reservoir provided on the back surface side of any one of the pressure teeth and configured to store water to be applied to the sheet, and a pressurizing member (piston) that pressurizes the water in the water reservoir to apply water to the sheet crimping range.

A sheet binding apparatus includes a stack portion on which sheets are stacked; a manual setting portion, different from the stack portion, to which sheets are manually set from an outside of the apparatus; a first binding portion binding sheets stacked on the stack portion and set on the manual setting portion, the first binding portion being movable to a first position where sheets on the stack portion are bound and to a second position, different from the first position where sheets set on the manual setting portion are bound; and a second binding portion binding sheets stacked on the stack portion, the second binding portion being different from the first binding portion. The first position is set, with respect to a moving direction of the first binding portion, between the second position and a third position where the second binding portion binds sheets stacked on the stack portion.

Within an area of substantially regular hexagons arranged at regular intervals on an imaginary reference plane, a sheet material includes a concave-convex section (20) having a basic pattern in which one first region (A1) is surrounded by six second regions (A2). This basic pattern repeats in regular intervals in lateral and longitudinal directions of the sheet material. The concave-convex section includes first protruding portions (21) and second protruding portion (22), which protrude in opposite directions from each other in the thickness direction in the first regions and the second regions, respectively. The first and second protruding portions may have a hexagonal pyramidal shape or a truncated hexagonal pyramidal shape.

It is arranged to obtain charging voltage when charging voltage is applied to a nonaqueous electrolyte type lithium ion secondary battery and discharging voltage when a discharging current is generated by the battery. A coefficient of a quadratic term of an approximated curve of a quadratic function with respect to changes in value within a sampling period for each of the charging voltage and the discharging voltage is calculated. This calculation is repeated over a plurality of the sampling periods. Based on occurrence situations of symmetry phenomenon and intersection phenomenon in the calculated coefficients, it can be determined whether or not there is a possibility of lithium deposition without disassembling the battery.

A sheet material (1) includes a stiffness-increasing concave-convex part (20). A first reference plane (K1), an intermediate reference plane (K3), and a second reference plane (K2) serve as a reference system. The intermediate reference plane is partitioned by first lattice straight lines (L1), second lattice straight lines (L2), and third lattice straight lines (L3) so as to define hexagonal unit areas (24) and triangular unit areas (25) in the intermediate reference plane. Areas that include a plurality of the hexagonal unit areas and the triangular unit areas are designated as first, second and third reference areas (214, 224, 234), respectively. Combinations thereof constitute new first, second and third reference areas (213, 223, 233), respectively. The concave-convex part includes first areas (21) and second areas (22), which respectively include the new first reference areas and the new second reference areas, and third areas (23), which include the new third reference areas.
