Title: Optical amplifier
Inventor: ONODA YOSHITO
IPC: G02F1/35
Filed: 1989-03-03
Abstract: PURPOSE:To increase the gain of the optical amplifier constituted by using a single progressive wave type optical amplifier by propagating light reciprocally in the progressive wave type optical modulator and amplifying the light twice. CONSTITUTION:Light which passes through a polarized light separating means 1, the progressive wave type optical amplifier 2, and a polarization plane rotating means 3 in this order is reflected by a reflecting mirror 4 and light which passes through a polarization plane rotating means 3 and the progressive wave type optical amplifier 2 in this order is outputted through the polarized wave separating means 1 through an optical path different from the incident light. The light, therefore, travels in the progressive wave type optical amplifier 2 reciprocally, so the light is amplified twice and the gain is increased. Consequently, the gain of the optical amplifier constituted by using the single progressive wave type optical amplifier can be increased.

Filed: 1997-03-06
Abstract: PROBLEM TO BE SOLVED: To use a debugging code for a debugger while executing an application by dynamically translating the block of a 1st code during the execution time of the 1st application and placing the debugging code inside the block of the translated code. SOLUTION: In order to generate a translated code, a dynamic translator 100 is used during the execution time. The block of the code from an application executable code 41 is translated at the time of execution. A debugger 99 inserts a conditional break point containing a conditional expression to be evaluated into the translated code. By communicating with the dynamic translator 100, the debugger 99 performs this insertion indirectly so as to show the kind of the set conditional break point and the position of that conditional break point inside the translated code 101. In that case, it is not necessary for the debugger 99 to stop the execution for evaluating the conditional expression.
