摘要:
A synchronizer ring having a stabilized friction characteristic relative to a taper cone and having sufficient mechanical strength and anti-abrasion characteristic. The synchronizer ring is made from a ferrous sintered alloy containing 0.2 to 1.0% by weight of carbon, 8.0 to 15.0% by weight of copper, 0.1 to 7.0% by weight of at least one component selected from a group consisting of chromium, manganese, molybdenum, and phosphorus, and balance iron and inevitable impurities. A free copper is precipitated in a matrix of the sintered alloy. Porosity of the sintered alloy is from 3 to 8 vol %.

In an image processing apparatus using a read buffer, in a case where access request target data is not stored in the read buffer, the read buffer is controlled such that data corresponding to a position having coordinates, which is most distant from a position having coordinates corresponding to the access request target data, is discarded or replaced. Consequently, the image processing apparatus increases the probability that data corresponding to a position close to a position corresponding to the access request target data remains in the read buffer. Accordingly, the hit rate of the read buffer is increased. Thus, the frequency of access to an external memory can be reduced.

A master device in a system including a bidirectional bus and at least one device manages whether the system is in an access state in which the master device permits an access to or from one device or a non-access state in which the master device permits an access to none of the devices. The master device drives the bidirectional bus using a predetermined current to transfer data to or from one device connected to the bidirectional bus when the system is in the access state. When the state of the system changes from the access state to the non-access state, the master device drives the bidirectional bus in order to stabilize the potential of the bidirectional bus to keep the bus potential from changing when the system is in a non-access state, thereby eliminating the need for conventional pull-up/pull-down resistors for stabilizing the bus potential during a non-access state.

摘要:
A processor performance analysis device analyzes performance of a multithreaded processor in a system LSI which includes: the multithreaded processor which executes processing in parallel using multiple logical processors; a functional core which executes processing different from the processing executed by the multithreaded processor; and a memory interface which receives each access request and controls access to memory. The processor performance analysis device includes: an operational information output unit which monitors the multithreaded processor to output operational information; an access information output unit which monitors the memory interface to output memory access information; and an analysis information output unit which analyzes the performance of the multithreaded processor using the operational information and the memory access information.

A sintered Fe alloy for a valve seat is made of a prepared powdery alloy which comprises C of from 0.3 wt. % to 1.6 wt. %, Cu of from 5 wt. % to 20 wt. %, hard particle of from 5 wt. % to 40 wt. % which consists of at least one species selected from ferroalloy, ceramic and intermetallic compound, and a balance which is a powdery Fe atomizing alloy containing at least one species of from 1 wt. % to 8 wt. % selected from Cr and Mo. The prepared powdery alloy containing the above-mentioned component and content is subject to a press forming process by a compression molding to form a green compact body which is then sintered. The sintered Fe alloy has a high thermal conductivity, a high strength at a high temperature and an excellent abrasion resistance, and, moreover, can be used for a valve seat provided in a high function engine.
