Patent EP-0469282-A2 (EP)
Inventor: STORLIE CHRIS A
IPC: G03G15/01
Filed: 1991-06-21
Abstract: A method and system for controlling the alignment and registration of color images such as those of cyan, yellow, magenta, and black (C, Y, M, K) which are successively printed on a photoconductive drum (30, 76) and then transferred from the drum to paper (44) during electrophotographic color printing. Each successive color image printed on paper is fused (36, 38) therein, and then vertical, horizontal and angular error signals are generated (56) after each fusion (36, 38). These error signals represent the difference between an original image reference position and the image position after each color image fusion into the paper. These error signals are then processed (60, 62) in a closed loop feedback control system in such a manner as to control (104, 102, 98) the position and scan rate of a laser beam (96) being projected onto the photoconductive drum (30, 76) to thereby cause the next-printed color image to be aligned with the previously printed color image. In this manner, the electro-optical control of each successively printed latent image formed on the photoconductive drum (30, 76) is responsible for the above alignment and paper correction without requiring complex mechanical schemes to accomplish same.

Abstract: In a gas valve control system including a microprocessor (5), a first relay (1 K), a second relay (2K), a flame sensor (60) and a timer (40) said timer controls a switch (55) which is connected in the power supply path of the second relay. The second relay controls the gas valve (25). Activation of the first relay (1 K) causes activation of the second relay (2K) which causes the valve (25) to open. Also, activation of the first relay causes the timer (40) to operate. The flame sensor (60) then must sense flame or else the microprocessor (5) will deactivate the first relay (lK). If the microprocessor fails to deactivate the first relay, the timer (40) causes the switch (55) to open and break the power supply path to the second relay (2K). This in turn causes the valve (25) to close.

Abstract: An improved linear motor device is disclosed having a vibration reduction unit. The linear motor device can be applied to a copying machine. As a magnetic field forming device (36) receives reaction force and is moved, in the opposite direction to the movement of movable members (10a, 10b), vibration is not transmitted to a base frame (1). The magnetic field forming device is carried to a most suitable position for absorbing the vibration by a driving device (40) employing a pulse motor. A velocity reduction ratio in a velocity reduction mechanism of the driving device is set to be different from a velocity reduction ratio under an ideal condition in which frictional force is neglected. As a result, the magnet field forming device can be driven by a smaller pulse motor.

Abstract: In order to control wheel spin in a vehicle driven by an internal combustion engine, a spin calculator (7) determines the amount of wheel spin and compares (8) this with a target value. If the target value is exceeded, an engine controller (9, 10) reduces engine output demand, for instance by reducing the opening of a throttle (12). A fuelling controller (14-19) forms a threshold value which is inversely dependent on the difference between the reduced engine output demand and the actual engine output demand. When the wheel spin exceeds (18) the threshold value, the controller (19) cuts off the supply of fuel for a predetermined pattern of engine fire events.

Abstract: Disclosed is an improved method and apparatus of automatically terminating connector pieces to a plurality of insulated wires in which insulated wires of desired lengths are prepared. Right connector pieces (R) are terminated to the right ends of the cores of said insulated wires and left connector pieces (L) are terminated to the left ends of the core conductors of the insulated wires or the left ends of the insulated wires may remain unterminated. Right connector pieces each having terminals fixed thereto are displaced from an initial position to a terminating position. The right connector pieces are terminated to the right core conductor ends of the insulated wires at the terminating position. The right connector piece terminated to the right core conductor ends of said insulated wires are displaced to the initial position which results in pulling the insulated wires out of a wire supply against a resilient tension which is applied to the insulated wires for withdrawal toward said wire supply. The insulated wires are pushed down at the intermediate position between the initial- position and the terminating position to a predetermined lowest level against the resilient tension. A selected insulated wire or wires which are desired to have the longest length are held at the lowest level while allowing the other insulated wires to resiliently rise up to a predetermined second lowest level, thus measuring the second longest length of wire. This measuring operation is repeated until all the insulated wires are clamped and set at of their desired lengths. The insulated wires are then cut at their left ends and the left connector pieces are optionally terminated to the left core conductor ends of said insulated wires, or they remain unterminated.

Abstract: Recombinant hepatitis B virus surface proteins produced in recombinant host cells are rapidly and efficiently purified from heated whole cells at neutral pH. The whole cells are heat treated, cooled and in the case of high pH extract, the pH is reduced. The surface proteins are then adsorbed onto wide pore silica followed by elution and concentration. This method eliminates the requisite introduction of protease inhibitors, stabilizes the surface protein and improves product yield.

Abstract: The second harmonic wave of the solid laser light which is emitted from a second harmonic wave light source is divided into a plurality of laser beams by a diffraction grating. The divided laser beams are converged on a record carrier into a plurality of light spots by an optical head. Magnetic field generating coils for applying magnetic fields to the respective light spots in accordance with the recording signals from a signal line are disposed under the record carrier. Part of the solid laser light is reflected and input to a beam splitter. Since part of the light input to the beam splitter is taken out and on the basis of the output, a stabilizer controls the output of the solid laser light from the second harmonic wave light source, parallel recording/reproduction using the plurality of light spots which are arranged on the record carrier is enabled and the formation of the plurality of light spots is effectively controlled. Thus, a magneto-optical recording and reproducing apparatus which is capable of high-density recording and high-speed data transfer, which supplies a stable and accurate optical output, and which facilitates the control of the optical output is provided.

Abstract: Disclosed is a method and apparatus for driving conventional 3-bit luminance digitally accessed LCD panels so as to provide a perceived greater number of colors than can be directly or digitally accessed. In one embodiment, spacial mixing is used to access adjacent pixels which, when viewed from a distance, appear to be a color average of the two pixels. In another preferred embodiment, temporal mixing is utilized such that each pixel is accessed two or more times so that the time-wise average luminance level is perceived by the observer. In a further preferred embodiment spacial and temporal mixing are used to provide a "real time" or "on the fly" embodiment which provides accurate 5-bit perceived color displays. In a further embodiment, the use of a dual port frame store allows video to be clocked in to the storage at a conventional video rate but the data can be clocked out at a much higher rate so that a greater amount of temporal mixing can be utilized to provide 6-bit perceived color.
