Title: Flash fixing device
Inventor: OZAWA MASATAKA
IPC: G03G15/20
Filed: 1980-12-24
Abstract: PURPOSE:To obtain a flash fixing device with a high efficiency and low noise characteristic by specifying irradiating time corresponding to the electric energy for flash discharge. CONSTITUTION:In the figure showing the relation between a radiating time tau and accumulated electric energy W, when the electric energy for one time flash discharge is <=1,000J, the radiating time is in the range lower than the part of a slanting line in the figure. And in order to reduce the level of noises to <=90 phone, flashing discharge may be carried out in the region in the right side of the 90 phone line. Namely, arrangement should be tau>=(W/500-0.6)ms. Also, since the radiating time is made shorter, the smaller the electric energy for fixing, considering improvement of the efficiency, the radiating time tau is arranged that (W/500-0.6)ms<=tau<1.6ms. With this, a device for fixing by flash of high efficiency and of low noise is obtained.

IPC: G06F12/08
Filed: 1997-06-26
Abstract: PROBLEM TO BE SOLVED: To enable efficient cache allocation by caching data structure after one avoidable cache error. SOLUTION: A computer system 100 is provided with plural subsystems 110, 120,...180 mutually linked through a global interconnect 190. Peculiar network node addresses are allocated to the respective subsystems. When a cache error is detected, it is determined whether that cache error can be avoided or not. Namely, when data are cached before and further remaining yet in a cache, it is determined whether the current cache error is to occur in spite of that or not. Only after the avoidable cache error occurs, data are to be cached. The data are cached only after one avoidable cache error at least in place of every access.
