An engine vibration sensor for detecting the engine vibration as an electric signal including a vibrator set to resonate at a specific frequency of vibration of an engine to which it is attached, the vibrator being composed of at least one piezoelectric plate and having a root and a vibrator element; means for increasing the cross-sectional area of the vibrator element to make the second moment of area of the root of the vibrator relatively larger than that of the vibrator element; a base to be connected to an engine body; and a clamp for retaining the root firmly between the clamp and the base. The clamp may be provided with a projection having a flat surface for retaining the root of the vibrator. This construction prevents a change in the effective length of the vibrator element, thereby stabilizing the characteristics of the resonant frequency of the vibrator.

A gateway (GW) for relaying a communication between a public telephone network and a routing server for managing use status of the GW and a network are provided on the internet. When a connection request is received, the GW issues a request to retrieve a route in which the costs are minimum and a necessary bandwidth can be reserved. The routing server retrieves the route of the minimum costs using the bandwidth reservation status of the internet and the partner's telephone number and notifies the request issued GW of the address of the partner GW. The costs at that time point may be notified to the user and the user selects whether the communication is performed or not. By managing the current connection information established by each GW, if a necessary bandwidth cannot be reserved, an audio compression ratio may be changed.

In a digital copying machine, a ground in a document image is removed according to the type of document by referring to a histogram of reflectance data on a document image prepared for each line. A ground peak or a gradation level having the largest frequency in the histogram is determined. Further, frequencies are obtained in three windows appropriate for extracting characteristic quantities for ground, background and characters. A window for the ground quantity is determined according to the ground peak, and a ground range for removing the ground is determined by using the ground peak and the three frequencies. Then, the gradation data are corrected according to the ground range, and an image is formed on a sheet of paper according to the corrected gradation data. Thus, a ground can be removed by analyzing the histogram without a prescan.

The data backup device comprising a receiver unit receiving from an image forming apparatus via a network, backup data and sender information indicating the location of the image forming apparatus on the network; a memory unit storing the backup data and the sender information that are received; an operating state acquiring unit acquiring based on the sender information, the operating state of the image forming apparatus whether or not it is ready to receive the backup data; a judgment unit judging based on the acquired operating state, whether or not the image forming apparatus is ready to receive the backup data; and a transmitting unit sending back the backup data to the image forming apparatus based on the sender information when the judgment unit judges that the image forming apparatus is ready to receive the backup data.
摘要:
By adopting a method of requesting a band for each plurality of calls, or a method of requesting a band independently of origination or termination of a call, a method of reducing the frequency of origination of a call is provided. A first aspect may provide that a gate keeper requests security and release of a band not every call, but collectively for a plurality of calls, and the security and the release of a band are requested at frequency less than that of origination or termination of calls. A second aspect may provide that an estimated value of a time series change in necessary band is previously set in a gate keeper, and security and release of a band required for communication are requested depending on a time, but independently of origination and termination of a call.

An image processing device acquires composition guideline data containing information specifying a plurality of manuscript data sets and the printing order of the data sets. The image processing device accesses an external device based on composition guideline data to acquire at least one of the manuscript data sets from that external device via communication. A print instruction is issued such that the plurality of manuscript data sets specified by composition guideline data, including the acquired manuscript data set, are printed in the order indicated by composition guideline data. Thus, a plurality of manuscript data sets may be easily printed in a prescribed order based on composition guideline data.

A charging management server is informed of an ED number stored in an IC card, and a user charging table of the charging management server is read. A new user charging list is transmitted to an MFP. In the case where the MFP receives a cooperative job to be executed by a cooperative server, a sub charging list is generated. The generated new sub charging list is transmitted together with image data to the cooperative server. The cooperative server executes the job on the basis of charging a fee for the job. As the job is executed on the basis of charging, the sub charging list is updated. In parallel with the execution of the cooperative job by the cooperative server, the WP can perform a normal job according to the charging list.

Out of viewers of the same content, multi-user talking service is provided to only viewers who wish to enjoy the content in a large number of people. Only when an address of a terminal 4, 5 that has transmitted a request for participation in multi-user talking is registered in a viewer management DB (which manages viewers of contents), a content distribution/multi-user talking service center 1 registers the above-mentioned address into a participant management DB (which manages participants in multi-user talking) associating the address with identification information of a content that is registered in association with the address in question in the viewer management DB. Then, for each content, respective pieces of talking data received from addresses registered in association with identification information of said content in the participant management DB are synthesized to generate multi-user talking data, and generated multi-user talking data is transmitted to each of said addresses.

An audio gateway is provided for receiving an internet relay request and a number called in a call from a telephone via the internet. An audio data gateway is selected using the number called, and relay operations are performed with the selected destination audio data gateway. The relay audio data is multiplexed for streams based on multiple relay requests having the same relay destination so that the relay audio data in these streams are multiplexed into a single relay stream.
