A processing unit (processor) performs processing of programs. A monitoring unit measures the rate of operation of an instruction processor in the processing unit. Information which is a standard for judging modification of the performance is stored in a control information memory unit. A control unit judges on the basis of the operation rate of the processor collected by the monitoring unit and the control information stored in the control information memory unit whether it is necessary to modify the performance or not and controls to modify the performance of the processor on the basis of the judged result.

Performance control apparatus and method for data processing system

Lengths of arms of pressing members held at a lower end of an arm section of a cover member are determined in correspondence to the retention of semiconductor devices having contour dimensions different from each other, and are shorter than a length of the arm section so that part of the pressing members is projected outside through a recess of the socket body.

Socket for semiconductor device

A guide member is supported to be movable relative to an accommodation portion of a contact-moving member An engagement pin is engaged with a post portion so that the maximum displacement of the guide member is limited within the maximum displacement of a semiconductor element. The inner circumference of the accommodation portion of the contact-moving member is brought into contact with the outer circumference of the guide member so that the maximum displacement A of the contact-moving member is limited. Thus, a gap CL (=A&#x2212;B) is defined between the inner circumference of the contact-moving member and an end surface of the guide member opposed thereto.

Semiconductor device socket

A virtual machine system is constructed between a plurality of real machines of a multiprocessor system. In order to move a virtual machine operating in a virtual machine system on a given real machine to a virtual machine system on another real machine, each virtual machine system is managed by attaching a common logic name to the real machine resources. The origin of the virtual machine (VM) is notified of the logic name of the real resource corresponding to the VM configuration information. The destination VM includes a device for generating an identical VM configuration according to the logic name received thereby to realize the movement of the VM configuration. Also, the origin VM holds a new asynchronous operation request for the VM to be moved, and suspends the operation of the VM. The VM resource information and the asynchronous operation hold information are transferred to the destination. The destination VM restarts the VM operation in accordance with the received information.

System with virtual machine movable between virtual machine systems and control method

An accommodation portion for a semiconductor device to be mounted is formed of an accommodation portion of a positioning member that is restricted in its position to a socket body and supported on the same, and an accommodation portion of a positioning member that is supported on the socket body relatively movably with respect to the socket body.

Semiconductor device-socket

A semiconductor device-socket is provided, in which the amount of the movement of a contact deviation member is restricted by a protrusion P such that a predetermined gap CL is formed between a partition wall W and a movable contact portion A , and a predetermined gap CL is also formed between an outer peripheral surface of the partition wall W and a movable contact portion A

A recording apparatus having a carriage which scans along a guide shaft and which is provided with recording heads includes a position detector for detecting the positions of the carriage in the scanning direction; and a fixing device for engaging with the carriage to regulate the carriage in the scanning direction when it is detected by the position detector that the carriage is in a given fixing position and fixing the carriage in the given fixing position. With the structure thus arranged, this recording apparatus is capable of preventing the carriage from being bent or deformed when the ink tanks and recording heads are detachably mounted or the gap adjustment for the recording heads are executed on the carriage, thus enabling the operation and positioning of the carriage to be executed exactly.

Recording apparatus with structure for locking and supporting recording

A color ink jet printing apparatus including a single suction mechanism having a capping member designed to cap any one of the printheads of the apparatus and carrying out a suction recovery of that capped printhead. A plurality of additional caps which are not associated with the suction mechanism are provided for capping the printhead. Various printing moving schemes are devised to provide quick and efficient positioning of selected printheads opposing the suction mechanism to speedily service that printhead.
