Patent JP-S63102515-A (JP)
Title: Optical reception circuit
Inventor: TAKAHASHI MASAAKI
IPC: H04B10/572
Filed: 1986-10-20
Abstract: PURPOSE:To always attain correct AGC by using a pilot signal interruption output signal at the time of standby state from a control circuit to increase the gain of a 2nd AGC amplifier circuit more than that at the steady-state while using a photoelectric conversion rate changing circuit to decrease the photoelectric conversion rate of an avalanche photodiode APD more than that at the steady-state. CONSTITUTION:A setting voltage Vref is fed to an APD multiplier setting circuit 22 by a pilot signal interruption detection output to decrease the multiplication factor of the APD 10 more than that at the steady-state. On the other hand, the gain of a variable amplifier 34 receiving the supply of the pilot signal interruption detection output from a control circuit 18 is increased more than that at the steady-state to make the gain constant up to the input of the control circuit 18 regardless of the signal level to bring the titled circuit to be in standby-state for an incoming call. Thus, even if a strong optical signal reaches, no overload is exerted on a preamplifier 12, the control circuit 18 detects a pilot signal to apply AGC. Conversely, even if an incoming optical signal is too weak, since the pilot signal is amplified by the operation of a 2nd AGC amplifier 34, the AGC function is operated sufficiently also in this case.

When the temperature of the temperature sensing element 12 rises up to the specific temperature, a comparator 18 outputs a reset command signal to a flip-flop circuit 19. Thus, a pulse signal after the time width corresponding to the setting and presetting operation of the circuit 19 is obtained, so this time width is used as air flow rate measurement information. Consequently, high-precision engine control is performed.

Title: Method and device for analyzing working of microprocessor
Inventor: MATSUSHIMA NORIYUKI
IPC: G06F11/28
Filed: 1985-11-08
Abstract: PURPOSE:To easily analyze the working of a processor at high speed and with high accuracy by deleting the information unnecessary for the analysis of a single step action produced by a prefetching action. CONSTITUTION:An instruction 1 is processed in the periods T1-T4. However 'operation code of an instruction 2' that is unnecessary for the analysis of a single step action is inserted mistakenly to a period T3 owing to a prefetching action. This makes it difficult to analyze the operation of the instruction 1. The contents of a control signal memory circuit 14 are equal to 'L' in the period T3. When the contents of the circuit 14 are read out together with the contents of a bus state memory circuit 12 for the analysis of operations at and after a period T10, a simulator main body part 30 detects the operation code detecting signal 'L' stored in the period T3 and the 'L' that means the contents of the circuit 14. Thus the 'operation code of the instruction 2' of the bus state signal is never read out in the period T3 and the undesired data is deleted.
