Title: Monitor system of program runaway
Inventor: MURAKOSHI TAKASHI
IPC: G06F11/30
Filed: 1984-02-08
Abstract: PURPOSE:To detect runaway with the expiration of either of both watchdog timers by providing two kinds of watchdog timer for monitoring program runaway and setting a monitor time to one watchdog timer with a program and fixing a set time to the other with hardware. CONSTITUTION:After the program is started, a time slightly longer than an initial processing time t3 is set to an auxiliary watchdog timer (WDT)3 by a signal (d). Next, a signal (c) is outputted for the purpose of resetting and starting WDTs 2 and 3. If the initial processing is terminated within the time t3, a value slightly shorter than a normal processing time t4 is set to the auxiliary WDT3, and the WDT2 and the auxiliary WDT3 are reset and started for every processing. If the WDT2 is not reset over the runaway allowable processing time t4 during the normal operation, the auxiliary WDT3 expires, and a time over signal (g) is generated. This signal is outputted as a WDT signal (e) from an OR gate 4 and is used as a condition of restart or stop of the program.

Filed: 1982-02-10
Abstract: PURPOSE:To make the oscillating frequency highly stable against a temperature change, by picking up an output from a hybrid circuit, in an oscillator used for a millimeter wave band radio communication device. CONSTITUTION:In Figure, the entire circuit consists of a band pass filter 1' comprising a dielectric resonator, an amplifier section combined with reflection type FET amplifiers 6, 7 and a 90 deg. hybrid circuit 4, and a feedback type oscillator having a feedback loop with the hybrid circuit 5. They are made small in size and stable by adopting microwave integrated circuits. In this feedback type oscillator constitution, the entire circuit is separated into two parts; the amplifier section comprising the band pass filter 1' cosisting of the dielectric resonator, the reflection type FET amplifiers 6, 7 and the 90 deg. hybrid circuit 4, and the feedback loop comprising the hybrid circuit 5. Since each of them is adjusted for the frequency characteristics against temperature change by the measurements, the characteristics of the two parts are so designed that they are cancelled with each other against the temperature change, allowing to realize the highly stable oscillator.
