Title: Burnout detection device of resistance thermometer
Inventor: HARUHARA FUSHIAKI
IPC: G01K7/24
Filed: 1979-11-24
Abstract: PURPOSE: To make it possible to prevent misreading of the meaured value, by outputting a saturation output from the operational amplifier, in case when one wire of the three-wire conductor for connecting the thermometric resistor of the resistance thermometer, and the measuring instrument is cut off.  
     CONSTITUTION: In case of the regular operation, a constant current from the current source 1 is supplied to the conductor 2, the thermometric resistor R(t), the conductor 3, and the zero point set resistor RZ, and the variation of resistance value caused by a temperature of the thermometric resistor is output from the operational amplifiers 4, 7 as a variation of voltage. When the conductor 2 or 3 is cut off, a current does not flow into the thermometric resistor, voltage -V is applied to the positive input side of the operational amplifier 4, the comparatively high voltage of the current source 1 is applied to the negative input side, and therefore its output is saturated to negative. When the condutor 5 is cut off, the voltage -V is applied to the positive input side of the operational amplifier 4, and its output is saturated to negative. Accordingly, the output of the operational amplifier 7 is saturated to positive, and the output of the resistance thermometer which is not shown in the figure swings to the positive side.

Filed: 1980-10-29
Abstract: PURPOSE:To obstruct flowing of more current than necessary in an electromagnet and to prevent burning down of the electromagnet and destruction of an electromagnet driving circuit by a method wherein a driving signal is supplied to the electromagnet being limited only for the allowable driving period, and a reset signal is made to be generated when the signal is supplied exceeding the period thereof.

When the signal AS is normal, because output action of the signal AS finishes surely within the allowable driving period TBS set by a monostable multivibrator 9, an abnormal signal DS is not outputted from an NAND circuit 11. When the signal AS is outputted continuously after the lapse of the period TBS, the signal DS is outputted from the circuit 11, a reset signal ES is generated consequently from a monostable multivibrator 12 to reset a CPU2. Accordingly putting out of the signal AS from the circuit 3 is made to stop.

Title: Method and apparatus for recording and reproducing radar signal information
Inventor: RENEI EICHI CHIKUHANII
IPC: G01S7/285
Filed: 1988-06-20
Abstract: PURPOSE: To prolong the recording time of radar signal information by reducing the band width per channel by giving a prolonged pulse which is coincident with the leading edge of a master trigger pulse and having relatively prolonged duration. CONSTITUTION: A parallel-series converter 21 receives azimuth data through a plurality of parallel lines and serially inputs the data to a recording and reproducing device 13. A pulse prolonging device 23 having a one-shot multivibrator receives a master trigger signal and outputs a high-speed rising output pulse which is coincident with the leading edge of a master trigger pulse. By appropriately selecting the time constant of the multivibrator, the duration of the prolonged master trigger pulse is made coincident with the band width of a channel to be recorded. The prolonged output pulse of the device 23 is given to a detector 15 and the elongated mater trigger pulse is periodically sampled at a certain multiple of the internal clock speed. The prolonged master trigger signal minimizes the sampling error and reduces the band width required for recording.
