IPC: G06F12/00
Filed: 1988-09-22
Abstract: PURPOSE:To widely reduce the block range of processing at the time of system recovery and a range, in which history information are investigated, by deciding the position information of a part updated by a processing request, for which the processing is not completed and updated result is not reflected to an external storage device, and storing the information. CONSTITUTION:At first, a history information analyzing device 3 investigates which processing request the history information are correspondent to from the history information. When the history information correspond to the processing request which appears for the first time, the identification name of this processing request and the successive number of the history information are added to the list of the uncompleted processing request. Then, information such as the position of a memory 2, which is updated by the processing request from the history information, or the position of an external storage device 6 are housed with being made corresponding to the processing request. When a system trouble is recovered, a recovery processing part in a CPU 1 blocks an access from the other processing to the part and permits the access to the other part from the position information updated by the uncompleted processing request. Parallelly, the CPU 1 reads only the history information part of the uncompleted processing request and returns the contents of the memory 2 to a correct condition just before the system trouble. Thus, when the system trouble is recovered, the block range and range, in which the history information are investigated, can be limited.

IPC: G02F1/225
Filed: 1998-08-25
Abstract: PROBLEM TO BE SOLVED: To enable the intensity modulation of output signal light by using a drive circuit of simple modulation voltage by manufacturing the well layers of respective multiple quantum well structures(MQW) constituting branched two optical waveguides from different film thicknesses or different materials, impressing the same modulation voltage thereto and effecting phase modulation varying in the respective waveguides. SOLUTION: The MQW layers constituting the optical waveguides 9, 10 are so formed that their refractive index increases with an increase in the impressed voltage, on one hand, and decreases on the other when the same modulation voltage is impressed thereto. Namely, the MQW structures of the first optical waveguide 9 and the second optical waveguide 10 are composed of the MQWs varying in the thicknesses of the well layers. The change rate of the refractive index with the impressed voltage may be changed by changing the thicknesses of the well layers of the MQWs constituting the two optical waveguides 9, 10. The arbitrary setting of the change rate of the refractive index of the optical waveguides with respect to the modulation voltage is made possible by changing the structures and materials of the MQWs in the manner described above.
