There is disclosed an image display control system comprising a display device for forming an image, a detection device for detecting the moving direction or moving velocity of the visual axis of an eye of the observer, and a control device for controlling the display state of the display device according to the detection signal from the detection device, or an image display device capable of detecting the moving direction or moving velocity of the visual axis thereby anticipating the position o...

A cutting device includes a cutting mechanism, a hitching structure designed to be connected to a motor vehicle, a support beam joined to the hitching structure and to the cutting mechanism and a traction device. The traction device is comprised of at least one draw-spring designed to lighten the cutting mechanism during operation and a control device designed to void the action of the at least one draw-spring when the cutting device is placed. The control device has, among other things, a rod a...

A electronic device is disclosed having an underlying conductor formed in a predetermined pattern on a surface of an underlying insulator and made of at least one member selected from the group consisting of Ti, Ta, Mo, Cr, Nb and W and their alloy, a main conductor made of Cu formed in a predetermined pattern on the underlying conductor, a first coating conductor made of at least one member selected from the group consisting of Ti, Ta, Mo, Nb and Ni and their alloy, and a second coating conduct...

A fixing device has a fixing roller, a press member disposed in a press state in an axial direction of the fixing roller on the periphery surface thereof, and a transport guide for guiding transport of paper. The press member is formed so that the free height of a guide part on an upstream side with respect to the transport direction of the paper is lower than that of the pressure portion pressed to the fixing roller via a heat resistant sheet. Therefore, since the apparent elasticity hardness o...

A semiconductor device includes a superlattice having a first semiconductor layer having a first band-gap, a second semiconductor layer having a band-gap narrower than the first band-gap, the superlattice having a band structure with an energy level of a conduction band of the second semiconductor layer being lower than an energy level of a conduction band of the first semiconductor layer and an energy level of a valence band of the second semiconductor layer being lower than an energy level of ...

The present invention relates to an optical element fixing device, and particularly to a prism mounting device for an optical device using light beam which passes through a prism or lens, a lens fixing device for aligning and fixing the center of a lens with a prescribed optical axis, and a device for fixing a reflecting mirror of an optical device. The invention can easily and securely position the prism to be press-contacted to the lens within a case, in which changes in the magnitude of press...

A developing device capable of high quality image recording by separating a toner supply chamber for supplying toner to a developing roll and a toner recovery chamber for recovering regulated toner by a regulating blade from each other by a sheet-shaped member thereby stabilizing the toner supply to the developing roll and the toner recovery.

A tint mixing apparatus having a supply shelf in the form of a lazy-susan and having a plurality of vertically disposed rotating supply decks for the paint containers holding the basic tints. The supply decks can be moved vertically and the lower decks are provided with recesses at their rims which are larger than the support platform of the scale and bypass this platform when the lower decks are moved in a vertical direction.

A rotatable pin cylinder and a coacting backing or anvil roller define a nip through which die cut and creased sheet material is fed to have intervening waste pieces removed. A hollow cylinder or combing drum is telescoped over the pin cylinder for rotation about an axis which is eccentric with respect to the pin cylinder axis. The drum and cylinder and driven in unison and as they rotate through a complete cycle, radially projecting stripper pins carried by the pin cylinder are caused to projec...

This invention relates to improvements in a roller device by which articles placed on a roller face are moved in a desired direction in a plane, and composed of a main body, a plurality of rollers mounted around the periphery thereof with a cylindrical boss included in the main body and adapted to receive a shaft for mounting a plurality of the devices.
