摘要:
Disclosed are a frequency modulation apparatus and a frequency modulation method for generating an image clock that is used for turning on/off a laser beam that scans an image bearing member, such as a photosensitive drum. The frequency modulation apparatus divides, into a plurality of segments for each pixel, a main scan line on an image bearing member, and calculates auxiliary clock periods based on a reference clock period and variable-magnification coefficients corresponding to the segments. Then, the frequency modulation apparatus generates image clocks for the respective segments based on an initial predesignated period value and the obtained auxiliary clock periods. Furthermore, the frequency modulation apparatus includes a detecting device for detecting a difference between a reference value stored in a memory and an actual laser irradiation location, and corrects a shift in the laser irradiation location in accordance with the detection results obtained by the detecting device.

In the present invention, processing for a service such as reducing the charges placed on electronic mail transmitted and received within a predetermined group is performed efficiently. An electronic mail charging system comprises: a user database storing information specifying a mobile communication terminal in association with the group ID of a group to which the terminal belongs; an ID comparison unit for detecting the transmission of an electronic mail from a transmission terminal to a reception terminal, obtaining information specifying the transmission terminal and reception terminal from the electronic mail, referring to the user database on the basis of this information, and comparing the group ID corresponding to the transmission terminal with the group ID corresponding to the reception terminal; and a charging server for generating charging information in order to place charges on the transmitted electronic mail on the basis of the result of this comparison.
摘要:
A power-line communication device in which a control signal is superimposed on a power line between a switching power supply and a unit to be controlled to which an output of the switching power supply is supplied, so that the control signal is transmitted to the unit. At the same time, a switching noise generated by the switching power supply is monitored and communication is started by using the switching noise, as a synchronizing signal. Subsequently, communication can be performed during the intervals between the switching noises so that erroneous signal detection is reduced.

A picture coded signal decoding apparatus for decoding a plurality of picture coded signals into one picture signal. The apparatus includes a code string editing unit which edits the picture coded signals to generate one picture coded signal, and a decoder which decodes the one picture coded signal to generate one picture signal. The code string editing unit generates the one picture signal representing a composite picture including pictures corresponding to said picture coded signals. Each picture coded signal includes at least one coded sub-picture representing a sub-picture having a predetermined number of scanning lines. Each coded sub-picture includes a positional code for indicating a sequential position of the sub-picture in the picture coded signal. The code string editing unit includes an extracting unit which extracts the coded sub-picture included in each picture coded signals from each the picture coded signal, a connection unit which connects the extracted coded sub-pictures in a predetermined sequence, and a numbering unit which changes the positional codes at sequential positions according to a predetermined rule.

A recording and reproducing apparatus of the present invention has reproduction change detector for receiving information indicative of a detection of a reproduction operation from an in-reproduction detector, and a record change detector for receiving the information indicative of the detection of the reproduction operation of recording parts from in-record detector, thereby having excellent operability by simple switching operation.
摘要:
An optical fiber reinforcing structure and method of manufacture thereof for reinforcing an optical fiber having a cladding portion removed to expose a fiber core portion. The optical fiber with the fiber core portion is placed in a longitudinal groove of a reinforcing member. The optical fiber is fixed to the reinforcing member at the ends of the longitudinal groove using an adhesive. A cover is then fixed to the reinforcing member to hermetically seal the optical fiber within the longitudinal groove. The reinforcing structure of the present invention prevents environmental conditions from adversely affecting the optical characteristics of the optical fiber.
