Abstract:
Communication arrangements wherein each of ONUs of a first or second PON transmits data toward a connected first or second OLT after a wait time period designated by the connected first or second OLT; the first communication device of the first packet communication network sends a first frame for measuring communication time period, to the second communication device of the second packet communication network through the first PON, and sends a second frame for measuring communication time period, to the second communication device through the second PON; and the second communication device calculates a difference of communication time period between the received first and second frames, and instructs the first or second OLT of the first or second PON, for correcting a wait time period which is set to the one or plural ONUs connected to the first or second OLT, based on the difference between communication time periods.
Abstract:
An image forming apparatus includes an image carrier and a detection unit. The image carrier is stretched around a plurality of rolls. The detection unit detects a density of a toner image formed on the image carrier, based on an amount of regularly reflected light from a surface of the image carrier. A detection length where the detection unit performs the detection in a movement direction of the image carrier is longer than a length, in the movement direction of the image carrier, of a deformation area where a deformation of the image carrier is caused.

Abstract:
In the case of the on setting of an eco switch signal ESW, when a torque demand Tr* is less than a good fuel consumption-assuring minimum torque Temin, the hybrid vehicle of the invention stops the operation of an engine and controls a motor MG2 to output a required torque for constant speed drive. When the torque demand Tr* is not less than the good fuel consumption-assuring minimum torque Temin, on the other hand, the engine is driven at a drive point in a good fuel consumption range among drive points on an optimum fuel consumption operation curve to ensure output of the required torque for the constant speed drive. Such control enhances the fuel efficiency for the constant speed drive.

Abstract:
A measurement control apparatus designed to automatically select an interface circuit compatible with a measurement controlled object without error. A measurement control processor outputs interface setting data for setting one interface circuit compatible with the measurement controlled object in advance of output of measurement control data to the measurement controlled object. Based on this, an interface setting means activates only that interface circuit. Further, the processor is provided with a loopback unit for returning the interface setting data to the measurement control processor and confirms the match of the output interface setting data and the returned interface setting data. Further, it is provided with an identification code setting means for setting an identification code unique to an interface board mounting the interface circuit and confirms that the interface board has been correctly selected.

Abstract:
A communication system is provided which allows synchronous devices in different synchronous communication networks to have synchronous communications with one another via an asynchronous communication network. In the communication system of the present invention, a master communication device generates a master clock based on a reference clock which is provided by a clock supplier. The master communication device sends a synchronization information frame, which contains information about the generated master clock, to plural slave communication devices via the asynchronous communication network. The slave communication devices each reproduce the master clock from the received synchronization information frame.
