Abstract: To provide a stacked piezoelectric device which is inexpensive and excellent in bonding strength between a piezoelectric layer and an internal electrode layer, the piezoelectric device comprises piezoelectric layers and internal electrode layers containing not less than 50 percent by weight of Cu stacked alternately. Between the internal electrode layer and the piezoelectric layer, there is a diffusion region formed by mutual diffusion of components of the internal electrode layer and the piezoelectric layer to the other layer and comprising at least one component of the piezoelectric material and Cu. The diffusion region occupies not less than 90 percent of area of interface between the internal electrode layer and the piezoelectric layer, and a thickness of the diffusion region is not more than 10 percent of a thickness of the internal electrode layer.

Abstract: A hand held hole punching device having a shaft and a main body with a device for axially moving the shaft in a reciprocating motion. The tool head is connected to the shaft and includes a fixed portion fixed to the main body to slidably engage the shaft so that the shaft is permitted to slide axially relative to the fixed portion. Also, a movable portion is fixed to the shaft so that the movable portion moves axially with the shaft and the movable portion and the fixed portion cooperatively define at least two hole punchers. Each hole puncher has a punch pin that is different from a punch pin of any other hole puncher on the tool head.

Abstract: An improved hole-punching pliers has a holding part and a pressing part that are in pivotal combination with each other by way of a pair of connection plates. The holding part and the pressing part are provided respectively with a dentate engaging section so that they can be partially in mesh with each other in assembly to provide a secondary fulcrum in addition to the connection plates. Thereby when the holding part and the pressing part are held by a pair of connection plates and pressed with force, the mesh of the dentate engaging sections of the holding part and the pressing part can produce a double lever effect, rendering effective transmission of force applied to the holding part and the pressing part to punch a hole on an object.

Abstract: The invention provides a tool which can be used with a punch press. On such tool includes a marking punch which has a recess; a marking punch magazine having a channel in which the marking punch is received and an external surface having a transverse groove therein which is in communication with the channel; a striker which strikes the marking punch to move the marking punch from its rest position to its marking position; and a resiliently compressible body received in the transverse groove of the magazine and in the recess in the marking punch. This compressible body desirably is compressed between the magazine and the marking punch when the marking punch is in its marking position, but resiliently biases the marking punch towards its rest position. The invention also provides a method of marking a workpiece, which method can employ such a tool.

Abstract: A tag punch system for punching symbols into livestock identification tags or other target materials comprises a handle system, a pressure positioning system located on a first handle of the handle system, and a punching system located on a second handle of the handle system. The punching system has one or more stencil chains, having a plurality of user-selectable stencils. A target material is positioned and secured over a slider stencil of the pressure positioning system, a desired stencil is selected and brought into position, and the two handles are squeezed together causing the stencil symbol to be punched into the target material.

Abstract: An apparatus for forming a selectively-shaped paper cut-out comprises a cutting table assembly which has a plurality of cutting means disposed therein, In one embodiment, the cutting table assembly is rotatably mounted to a base member within a U-shaped support bracket extending therefrom. In another embodiment, the cutting table assembly is not mounted on a base member; rather, it has the necessary actuating means in place to independently actuate each of the plurality of cutting means provided therein. To use the apparatus, a user simply turns the cutting table assembly to choose the desired shape, inserts a sheet of paper into the assembly, and punches out the desired shape.

Abstract: A new and improved hand-held seam notching apparatus includes two double-armed lever assemblies. A first double-armed lever assembly includes a first handle portion, a first fulcrum portion, and a first jaw portion. The first jaw portion includes a first well portion and a first cutter assembly received in the first well portion. The first jaw portion also includes a first connector for connecting the first cutter assembly to the first well portion. A second double-armed lever assembly includes a second handle portion, a second fulcrum portion, and a second jaw portion. The second jaw portion includes a second well portion and a second cutter assembly received in the second well portion. The second jaw portion also includes a second connector for connecting the second cutter assembly to the second well portion.

Abstract: An improved tire puncturing device includes a base plate having a plurality of drive pins whose axes are formed in a plane perpendicular to the plane of the base plate. The drive pins extend from one side of the base plate and include a free end which forms a piercing point. Each of the drive pins are secured in the base plate and have an aperture formed therethrough for enabling fluid to enter the aperture at the piercing point and exit the drive pin at the other side of the base plate.

Abstract: A punch and embossing device for punching out or impressing a plurality of designs in a sheet. The device includes a base, a multiple punch cassette and a handle. The handle is pivotally connected to the base. The base has a punch station disposed adjacent the handle. The base station comprises a platform parallel to the plane in which the axis of pivot of the handle is disposed to support the cassette. The handle contains a member which contacts the cassette when the free end of the handle is pivoted toward the base. The cassette comprises a first plate containing a plurality of punches and a second plate each containing a plurality of dyes each of which is aligned with one of the punches and has a complementary shape to the punch shape. The first plate normally being spaced from and spring urged away from the second plate so that a sheet may be placed between the plates.

Abstract: An instrument for pressing items out of receptacles in a storage card, the card having open topped recesses which are closed by a burstable foil layer. The instrument includes a pair of arms which are held together in scissor fashion or by a resilient connection at their ends. One arm has a flat face protruding collet jaw. The other arm carries a counter member having an annular through hole or receptacle for receiving the collet and the item pressed from the card when the collet is pressed against the closed end of the recess and toward the counter member. The counter member supported on its arm may have a plurality of different size receptacles, and the base of each receptacle may be defined by the arm on which the counter member is supported. Also, the counter member on the arm may be replaceable with another counter member.

Abstract: A turret-type hand punch adapted primarily for punching holes in leather, imitation leather, or other plastic material. Means are provided on the punch to receive the cut portions of the leather or the like and to retain the same therein during the punching operation so as to prevent the littering of the area where the punching is taking place, with the punched out pieces of leather and the like.
