The portable information apparatus has a battery, a boosting circuit for boosting a voltage of the battery, a battery voltage detector for detecting a voltage level of the battery, an oscillating circuit for generating CPU clock and a counting circuit for counting the interval from the start of the oscillation of the CPU clock to the time when it becomes stable. The apparatus negates the output of the battery voltage detector during the interval counted by the counting circuit so that it can prevent the monitoring of the battery voltage lowering in the time of usual performance from influencing of the battery potential drop due to the transient current at the start of the performance of the boosting circuit and the oscillating circuit.

The synchronous serial communication circuit transmits and receives data, which is added flag patterns for recognizing the coil winding direction at the first and last of data block, by the electromagnetic induction system using a pair of coils. So, the circuit provides modulation and demodulation circuits acting at the clock of twice of the transfer speed and a flag check circuit for recognizing the inversion of the coil winding direction by judging a state of the flag patterns included in the received data. The transmitted data is converted into the biphase signal by the modulation circuit and is transmitted by driving the coil using the biphase signal. The signal received by the coil is converted into the received data by the demodulation circuit. When the winding directions of coils does not agree, the flag check circuit recognizes the inversion of the coil winding direction and the received data is inverted by the demodulation circuit.

A working machine maintenance system having a plurality of working machines. A center server is provided that manages maintenance on the plurality of working machines by engaging in data exchange through bidirectional communication with each of the plurality of working machines via a communication line. The working machines each include an operation data storage device, an operation device operated to enter a maintenance work completion, a data transmission device, a data reception device, and a display device at which the maintenance information is displayed. The center server includes a data reception device that receives the operation data, the maintenance work completion data, and the maintenance data that have been transmitted, an operation database in which the operation data are stored, a maintenance database, a calculation device that calculates maintenance timing. and a data transmission device that transmits data related to the maintenance information.

Provided is a communication system for working machines, which makes it possible to transmit desired messages from sites, where the working machines are arranged, to their corresponding work administration centers at timings as needed. When a mail switch 10 arranged on a working machine 7 is operated to send information to a server 1, a terminal user-company identification unit 14 identifies, on the basis of a terminal information database 18, a user to which the information so received is to be sent. A user-company-dependent mail selection unit 15 selects customer information 19a on the user from a customer database 19. At a transmission mail creation unit 16, a corresponding new message 16a is created. The mail is then transmitted from a mail output unit 17. In this manner, a desired message can be sent from each working machine 7 at a remote location to the corresponding user at a timing as needed.

In order to provide a near field light head capable of guiding light efficiently to a near field light generating element, capable of being fabricated easily and at low cost and in correspondence with small-sized formation and thin-sized formation, the near field light head of the present invention has a transparent board including a near field light generating element at a lower face thereof. An upper face or the interior of the transparent board is formed with a lens to be opposed to the near field light generating element. The upper face of the transparent board is mounted with a single mode fiber. The single mode fiber is successively connected with a graded index (GI) fiber and a coreless fiber. An end face of the coreless fiber which is not connected to the GI fiber constitutes a reflecting face disposed at 45 degrees relative to the upper face of the transparent board. The reflecting face is arranged right above the lens.

The MFP 101 compresses the image data read by the scanner 102 using the JBIG format, and then stores the image data in the image-data storing unit 104. The converting unit 109 of the MFP 101 converts the stored image data into a specific file format and then outputs this converted image data. Herewith, the user need not have the MFP read the original source once again even when image data of that source is requested to be output in a different file format.

A method and system for managing a construction machine and processing apparatus therefor includes a controller 2 mounted on a hydraulic excavator 1 working in fields. An operating time for each of an engine 32, a front 15, a swing body 13 and a travel body 12 is measured and stored in a memory of the controller 2. The measured data is transferred to a base station computer 3 and stored in a database 100 inside the base station computer 3. The base station computer 3 reads, per hydraulic excavator, the data stored in the database 100 and then prepares and outputs a distribution graph of the number of operated machines with respect to the working time (engine running time) of the hydraulic excavator. While looking at the distribution graph, a machine maker estimates the number of hydraulic excavators to be renewed and estimates the sales quantity of hydraulic excavators, thereby setting up a production plan of hydraulic excavators.
摘要:
In a network cache and a cache control method involving the transfer of a large volume of data as the time of reproduction of multimedia data including video data, a stabilized data transfer is made by eliminating the waste of cached data or a useless cache processing which may be caused by the interruption of a user's operation. When a data transfer request from a user terminal connected to a local network is made to a server existing on the internet, a user request processing program starts a cache program. The cache program performs a cache processing independently of the data delivery to the requesting user terminal by the user request processing program so that even if the user's request is interrupted, the storage of transferred data into a cache file is performed without ceasing. Also, a required bit rate for data made an object of transfer is analyzed for comparison with a network throughput between the server and the network cache. When the network throughput is larger, the caching of transferred data is not performed so that the discard of data having been cached is not caused. Thereby, it is possible to prevent the cache hit rate from being lowered.
