A V-belt is mounted on a first fixed conical plate and second fixed conical plate of a lower unit, and an upper unit is made to descend. A first movable conical plate and second movable conical plate are installed in the upper unit, and the V-belt is gripped between the fixed conical plates and movable conical plates. When a rotary actuator of the lower unit draws a drawbar which extends below the movable conical plate downwards, a predetermined pressure is applied to the V-belt. The first movable conical plate and first fixed conical plate are rotated in this state to drive the V-belt, and a noise test is performed.

A data transfer system comprises a plurality of terminals; a plurality of high-speed data transfer units connected to the terminals through a network, each data transfer unit comprising a plurality of storage devices and a storage device group control device or unit for controlling readout of data from the storage devices, and dividing and storing data requested by the terminals; a virtual storage device group controlling device or unit for controlling readout of data from virtual storage device groups, each virtual storage device group being constructed by selecting a storage device from each high-speed data transfer unit; and an instruction conversion unit or device for receiving a data readout instruction on the basis of data requests output from the terminals, which instruction is given to the virtual storage device groups, from the virtual storage device group control unit or device, and converting the instruction into a data readout instruction to the storage devices from the storage device group control unit or device. In this data transfer system, the load for the data transfer processing is equally distributed among the high-speed data transfer units even when data transfer requests are output from plural terminals.

A power source apparatus for vehicles comprises first and second switch means respectively for controlling charging currents flowing from a rectifier of a generator to first and second batteries having equal open terminal voltages, and third switch means for controlling a current flowing through a field winding of the generator. The third switch means is controlled to be turned on/off in response to whichever of the voltages generated respectively by the first and second batteries is lower. The first and second switch means are controlled to be turned on/off on the basis of a duty factor set based on a voltage difference between the first and second batteries. When the voltage of the first battery becomes equal to or less than a predetermined voltage, that voltage being the lowest voltage that a starter motor needs to satisfactorily start an engine, the duty factor of the first switch means is made larger to charge the first battery with priority irrespective of whether the voltage of the first battery is larger than the voltage of the second battery or not.
摘要:
A cam plate is pivotably installed to the base plate by means of the pin, the base plate being to be secured to the lateral side of the seat cushion. The base plate has the toothed member pivotable installed thereon, and the toothed member has formed at the free end thereof a cam striker, concavity formed directed from the cam striker toward the base thereof and a projecting release hook contiguous to the end of the concavity. There is also formed on the cam plate a lock cam which supports the cam striker and also slides into the concavity, and a cut is formed in a portion adjoining the toothed member of the lock cam. There is installed to the toothed member a reverse spring which normally forces the lower teeth in such a direction as to engage the upper teeth. When the cam plate is pivoted in one direction, the opposite walls of the cut depresses the release hook. These walls will retain the release hook when the cam plate pivots in the opposite direction.

There are disclosed a method and apparatus for applying a strippable paint to a large-sized product finished with a sprayed coating, such as an automobile, to form a protective film on the surface of the coating. The product is conventionally kept in stock for a period of time before it is shipped. Contaminations such as dust are washed away from the surface of the product. Then, the strippable paint is applied, preliminarily dried, and non-preliminarily dried to form the protective film out of the strippable paint on the surface of the coating. This protective film is formed easily, appropriately, and reliably. The obtained protective film has a uniform and sufficient thickness. Even if the surface contains unapplied regions to which the paint should not be applied, the paint can be applied to the whole surface of the coating while avoiding the unapplied regions according to the invention. The application can be performed easily and reliably without leaving unapplied portions around the unapplied regions.
摘要:
In a data transfer system in which when a first to fourth terminals require reading data, the data are read out of a first to fourth storages to be stored in a first and second buffer memories while a first and second virtual groups of storages are alternately switched every constant cycle, and thereafter a first and second data sending units send the data stored in the first and second buffer memories to the terminals; on the other hand, when the first to fourth terminals require writing data, received data is divided in a way to distribute the process loads of data read and data write of the divided data equally into a first and second data transfer units. At the same time, the data are stored in the first and second buffer memories of the first and second data transfer units, and thereafter the data are written into the first to fourth storages while switching the first and second virtual groups of storages alternately. As a result, the load of transferring data to the terminals is not concentrated on a particular data transfer unit in the data transfer system, even when the rate of request-to-reads from the terminals changes or differs from those of others.

摘要:
In an address formation circuit for an image processing, an address formation is separately processed in parallel like a pipeline by first and second address calculation means. The first address calculation means controllable by a program calculates a head address of a macroblock, and the second address calculation means calculates addresses of pixels within the macroblock on the basis of the head address calculated by the first address calculation means. An instruction memory stores the program and a data memory and a data file memory store address moving amounts required the calculations. A sequence controller controls an exclusive hardware. Hence, a high speed memory access like a real time image processing in the address formation can be possible and, when a complicated address pattern is required, an overhead of the address formation time in the instruction processing can be prevented.
