There is disclosed a mechanical pressing machine utilizing a rotation cam, in which an unbalanced inertia force, produced during a reciprocal movement of a slider, is canceled in a slider system without producing a large flexure in the whole of the pressing machine, thereby enhancing a dynamic precision. The slider and a balance weight are mounted respectively on an upper portion and a lower porti...

There is disclosed a mechanical pressing machine utilizing a crankshaft, in which an unbalanced inertia force produced during a reciprocal movement of a slider is canceled without producing a flexure in the whole of the pressing machine, thereby enhancing a dynamic precision. A balance weight, which is equivalent in weight to the slider vertically slidably supported on a frame, is slidably mounted...

There is disclosed a mechanical pressing machine of the general-purpose type which has advantages of a crank press, a knuckle press and a cam press. The pressing machine includes a slider which is mounted on a frame for vertical sliding movement, and has an upper press die mounted on a lower surface thereof, a pair of sliding blocks mounted respectively on right and left side portions of the frame...

The invention relates to a mechanical press which uses a cam plate (20), a nonbalanced inertia force generated during the reciprocating movement of a carriage (8) being eliminated without there being any overall deformation of the press, increasing dynamic accuracy. A cam plate (20) and a ribbed cam (21) are fixedly mounted to an end section of a drive shaft (13), the carriage (8) can be made to r...

What is described is a device for carrying out a method for securing layers of palletised products. A frame (1) consists of two pairs of mutually parallel rods (2, 3; 4, 5). The rods (2, 3) of the first pair of rods are provided at each of their ends with a guide (6), in which respective end portions of the rods (4, 5) of the second pair of rods are received slideably. Drive means act on the rods ...

An optical film made of multi-layered structure (25) which has a high-refractive-index layer (26) composed of titanium oxidic nitride, aluminum oxidic nitride, or silicon oxidic nitride.

The video cassette recorder selects channels in succession, determines the presence or absence of additional information included in the broadcast signal for the selected channel, and stores the selected channel regarded as a reception channel for the additional information when detecting the presence of the additional information in the broadcast signal. Further, the recorder extracts station ide...
