  • Patent number: 6785505
    Abstract: A fixing device includes an abutting member arranged at a position between an upstream side of a fixing roller and a downstream side of a heating roller in a moving direction of a fixing belt so as to abut against the fixing belt and expand a fixing region. The fixing device may also include a first supporting member and a second supporting member, which supports the fixing belt, etc., with respect to the first supporting member. An angle, formed between an approaching direction of a sheet-like recording medium and a line tangential to an upstream end of the fixing region in the moving direction of the fixing belt, is set equal to 20° or larger.

  • Patent number: 6636709
    Abstract: A fixing device for fixing a toner image on a recording medium includes a heating roller, a fixing roller, an endless fixing belt extended around at least the heating roller and the fixing roller and configured to be heated by the heating roller, a pressing roller disposed opposite to the fixing roller via the fixing belt, a temperature detecting member configured to detect a surface temperature of the heating roller, and a control device configured to control a surface temperature of the fixing belt at a predetermined temperature based on a surface temperature of the heating roller detected by the temperature detecting member. The temperature detecting member contacts a circumferential surface of the heating roller where the fixing belt is not extended around, such that the temperature detecting member is held in a low frictional relation to the circumferential surface of the heating roller.

  • Patent number: 6507054
    Abstract: A solid-state imaging device having contacts for a charge sweeping component or the like, with which increases in dark current can be suppressed while increases in contact resistance and the production of alloy spikes can be prevented, and a method for manufacturing this device. A solid-state imaging device has a charge accumulator for producing and accumulating signal charges when light is received, and a charge transfer component for transferring these signal charges, including a conductive layer 18 formed on a substrate 10, such as a silicon layer or metal wiring; an insulating film 21 formed over the conductive layer 18; an opening CH formed over the insulating film 21 and leading to the conductive layer 18; and a wiring layer 34 composed of aluminum containing copper in an amount between 0.4 and 5 wt %, formed at least inside the opening CH contiguously with the surface of the conductive layer 18.

  • Patent number: 6164698
    Abstract: A steering device is mounted in a limited space in a small engine compartment, thereby providing improved efficiency for assembly on production lines and improved vehicle maintenance. A steering column extends upward diagonally from in front of an engine into a driver's cabin. When seen from above the vehicle, the steering column extends from the front of the engine to driver's cabin through a space formed between the engine and a side member of a chassis frame. A steering shaft and a middle shaft of the steering column are connected via a joint, which passes along the side of the engine. The joint has a pair of tightening bolt holes, and serrations. Both shafts also have serrations mating with the serrations on the joint. One of the bolts is loosely fitted into one of the bolt holes during installation. A flat cavity on one of the joining shafts receives the loosely fitted tightening bolt. The flat cavity permits limited in and out motion of the joint for setting the final position of the joint.

  • Patent number: 6038411
    Abstract: An image forming apparatus having an image carrying member bearing an electrostatic image wherein the electrostatic image is visualized into a toner image by a developing device. The image carrying member is arranged for transferring the toner image to an intermediate transfer element while the image carrying member and intermediate transfer element are moving at a usual speed corresponding to the speed of movement of the image carrying member during toner image development. Multiple such toner images of different colors may be transferred in this manner to form multi-color images superimposed on the intermediate transfer element for subsequent transfer to a recording medium, usually paper.

  • Patent number: 5857887
    Abstract: In a method of manufacturing a cathode-ray tube having an electron gun in which a voltage-dividing resistor is disposed, metal straps are disposed on the right and left of the electron gun. When metal deposited films for stabilizing a potential are formed on the inner wall of a neck portion of corresponding portions or the like by a radio-frequency heating means, metal deposited films of substantially the same thickness can be formed.

  • Patent number: 5694638
    Abstract: An image generating device is provided with a control mechanism which controls an exit paper delivery speed after an image has been fixed to a form. The exit paper delivery speed is changed depending on information detected about the process of generating the image to prevent the form from being delivered with wrinkles. The information detected includes size of paper intervals between forms, length of forms, and whether the image generating process is a repeat copying or continuous form feeding process.
