Abstract: This invention relates to a rotational speed control system including a plurality of motor drivers for driving motors, and the object thereof is to drive a plurality of motors at the same rotational speed without depending on the number of motor drivers and without depending on the characteristics of each motor driver. A remote controller 31 and a motor driver 202 are connected to a motor driver 201. The motor drivers 201 and 202 control motors M11 and M12 at a prescribed rotational speed, respectively. A rotational speed instructing signal 91 indicative of the rotational speed is supplied from the remote controller 31 to the motor driver 201, and further supplied from the motor driver 201 to the motor driver 202. Because the rotational speed instructing signal 91 indicates a rotational speed which is transmitted in a digital value between the motor drivers 201 and 202, both of the motors M11 and M12 are driven at the rotational speed indicated by the rotational speed instructing signal 91.

Abstract: A system and apparatus for transmitting audio and video information to one or more subscribers terminal from a server. Each subscriber terminal includes a storage unit. The server selects an information distribution scheme (unicast or multicast) and sends the information to the subscriber terminal(s). Each subscriber terminal receives the information in accordance with the selected information distribution scheme, and stores the information in the storage unit. The system can cope with multiple requests from the subscribers without increasing the VOD service cost.

Abstract: An arrangement for transmitting audiovisual information to one or more subscribers terminal from a server. Each subscriber terminal includes a storage unit. The server selects a transmission channel and/or transmission rate in accordance with a type of information to be distributed and/or other factors. The server then distributes the information on the basis of the selected transmission channel and/or rate. The system can cope with requests flooding from the subscribers without increasing the VOD service cost.

The metal plate includes a plurality of first holes corresponding to cylinder bores, at least one second hole corresponding to another hole, and a side portion around the second hole. The sealing device is disposed on the metal plate outside the side portion relative to the second hole, and surrounds the second hole for sealing the same. The thin support portion is located inside the sealing device and is disposed on a part of the side portion around the second hole without extending the entire side portion. The support portion supports a part of a pressure applied thereto to securely seal around the second hole.

Abstract: In a self-luminous display panel driving system, one field of a composite video signal is divided into N sub-fields, luminance of each pixel is set by a pixel data. The pixel data comprises N bits corresponding to the number of the sub-field. A present pixel data of a pixel is compared with a prior pixel data of a same pixel and a change between a data of a highest luminance and a data of a luminance of a one digit lower is detected. An inter-frame change signal is produced when a change is detected. In response to the inter-frame change signal, the present pixel data is corrected so as to change the sub-field of the present pixel data.

Abstract: A plurality of air conditioning system control units are connected to each other through a communication line (20). Discharge resistors (R1, R2) are provided for discharging residual charges of the communication line (20). The control unit has a power superposition circuit (50) for applying a direct-current voltage and outputs an identification number signal from the power superposition circuit (50) to the communication line (20).

The gasket is basically formed of a metal plate and includes holes corresponding to the holes of the engine. The gasket includes a bead for sealing around the fluid hole, to which different tightening pressure is proportionally applied when the gasket is tightened. The bead includes at least one first portion where high tightening pressure is applied, and at least one second portion where moderate tightening pressure is applied.
