Abstract: An image forming device includes a plurality of developing devices and a photosensitive drum. Each of the developing devices includes a developer carrying roller. Preselected one of the developing devices is moved to a developing position confronting the photosensitive drum which is formed with a latent image. A first developing bias including a d.c. component and an a.c. component is applied to the developer carrying roller and developer on the developer carrying roller is rendered in contact with the latent image on the photosensitive drum so that the latent image is developed. On the other hand, when the developer on the developer carrying roller comes in contact with and separates from the photosensitive drum due to the movement of the developing device, a second developing bias is applied to the developer carrying roller. The second developing bias generates an electric field where the developer on the developer carrying roller is more reluctant to move toward the photosensitive drum as compared with the first developing bias. The second developing bias may include only a d.c. component.

Abstract: A frequency division multiplexed signal generating apparatus includes a distributor separating digital information signals into plural groups. Plural operation circuits convert the plural groups of the digital information signals into plural frequency division multiplexed signals, respectively. Plural peak detecting circuits detect peak powers of the plural frequency division multiplexed signals, respectively. Detection is made as to whether or not the detected peak powers are lower than a threshold power. In cases where at least one of the detected peak powers is equal to or higher than the threshold power, at least one of polarities of the plural frequency division multiplexed signals is controlled in a direction of canceling the peak power being equal to or higher than the given power. An adding circuit combines the plural frequency division multiplexed signals into a final frequency division multiplexed signal. <IMAGE>

Abstract: A balanced focus system and method achieve optimal focus of different areas of an object that are concurrently imaged and then combined to form a combined image. The balanced focus method is particularly suited for, but not limited to, use with an automatic inspection system for contactlessly measuring at an endface of an optical fiber termination the eccentricity of an optical fiber core relative to a theoretical ideal center of an alignment surface of the termination. The inspection system has an imaging system with a feature imager and one or more boundary segment imagers but preferably four in number, a focus adjustment mechanism (FAM) for adjusting the position of the imagers relative to the imaged object along an optical axis, and a machine vision system for receiving image data from the foregoing imagers and configured to control the FAM. The feature imager is positioned to capture an image of the feature ( e.g ., fiber core endface), and the one or more boundary segment imagers are positioned to capture an image of a corresponding boundary segment of the object ( e.g ., termination endface). The machine vision system determines the eccentricity based upon the feature image and the one or more boundary segment images. Significantly, the machine vision system employs the balanced focus system and method to achieve an optimal focus position for the imaging system based upon a series of combined images and a statistic S that is computed for each of the sampling locations.

Abstract: Method and apparatus for tracking the frequency and phase of signals in spread spectrum communication systems that makes more efficient use of available carrier frequency and phase information by utilizing a substantial portion or all of the energy occupying the frequency spectrum of a received carrier signal, including energy from communication signals intended for other system users. Multiple spread spectrum communication signals are input in parallel to data receivers where they are despread using preselected despreading codes at an adjustable phase angle and decoded over multiple orthogonal codes active within the communication system. Multiple decoded signals are then combined to form a single phase detection signal which is used by at least one tracking loop to track frequency and phase of the carrier signal for the received communication signals. The tracking loop generates a timing signal which is used to adjust the phase angle used during despreading. In further embodiments, the communication signals are despread using appropriate PN codes and separated into in-phase (I) and quadrature channels (Q) where data symbols are processed by fast Hadamard transformers to generate corresponding data bits. The data is formed into pairwise products between the channels and summed over multiple or all active subscriber orthogonal codes. This sum indicates a degree to which the estimated phase differs from the actual phase of received communication signals and is used to adjust the phase of application for the PN codes.

Abstract: With the object of reducing the circuit size and shortening the lock-in time of a DPLL circuit used in a receiver for radio data communication employing the GMSK modulation system, a data latch circuit (23) and subtractor (24) find the phase information difference for each symbol from the incoming phase data. A modulation component removal circuit (25) removes the modulation component from the phase information difference. A frequency error calculating circuit (26) integrates the phase information difference over an interval of n symbols, multiplies this integrated value by 1/n, and takes the result as the mean frequency error value for the interval of n symbols, and then outputs this to loop filter (32). A phase error calculating circuit (27) further integrates over an interval of n symbols the integrated value from the frequency error calculating circuit, and multiplies the result by 2/n. Adder (28) adds an initial phase latched by a data latch circuit (22) to the output of the phase error calculating circuit, and outputs the result to NCO (33) as the phase error value. Operation of loop unit (36) is commenced with a timing that is preset by the mean frequency error value and phase error value.
