Title: Fault detection system of compound type arithmetic device
Inventor: TOYODA EIICHI
IPC: B60L3/08
Filed: 1979-11-30
Abstract: PURPOSE: To make it possible to detect a fault of each arithmetic device exactly and fail-safely, by constituting the device so that the time for resetting a data request signal from its generation can be made shorter than the operation time of the fault detection means.  
     CONSTITUTION: In case when a data is not transferred from the device 31 due to a fault of the arithmetic device 31, although the arithmetic device 32 has output a data request signal A 2 , the signal A 2  is not reset all the time. Accordingly, the transistor TR36 remains conducting, exceeding the prescribed time, and therefore the fault detection relay 40 operates, and it can be detected that something abnormal has occurred. Also, in case when a coil of the relay 40 has been disconnected, outputs of the photocouplers 38, 39 die away, and the status becomes same as the data request signal A 1  or A 2  is being output, therefore the devices 31, 32 are able to detect it as an abnormal input. When the relay 40 cannot be driven due to a fault of the output buffers 33, 34 or TRs 35, 36, the devices 31, 32 are able to detect the fault according to the fact that the signals A 1 , A 2  which they have output themselves are not fed back.

Abstract: PURPOSE:To eliminate the need for the post treatment of powder solder and to facilitate the recovery thereof by ejecting the spheroidal powder solder having a specific value or below and a solvent into a vacuum chamber and bringing the powder solder into collision against each other or bringing the powder solder into collision against a rigid body, thereby deforming the spheroidal powder solder. CONSTITUTION:The spheroidal powder solder 1 of <=150mum obtd. by an atomization method using blowing of gaseous nitrogen and water 2 are force-fed into a pipe 4 connected at one end to the vacuum chamber 3. The inside of the vacuum chamber 3 is maintained under a reduced pressure by a vacuum pump 6 at all times. The pipe 4 may be heated by a heater 7. The spheroidal powder solder collides against each other or the spheroidal powder solder collides against the wall surface of the chamber 3 when the spheroidal powder solder 1 and water 2 increased in pressure in the pipe 4 are released into the chamber 3. The colliding part of the spheroidal powder solder is then deformed and is partly recessed. The water evaporates instantaneously as the b.p. thereof lowers. Only the spheroidal powder solder remains. The need for the post treatment of the powder solder after the deformation is entirely eliminated in this way and in addition, the recovery thereof is facilitated.

Abstract: PURPOSE:To estimate the mechanical character of a steel with definite grounds by selecting what is related to the mechanical character of the steel very much as the propagating speed of ultrasonic to be measured. CONSTITUTION:Transverse wave is transmitted to and received from the thick steel sheet 2 by an electromagnetic type transverse wave ultrasonic transmitter and receiver 21 so as to obtain the speed ratio of transverse wave VL/VC from the speed VL of the transverse wave of the polarization in a sheet rolling direction, which is transmitted in the thickness direction of the thick steel sheet 2, and the speed VC of the transverse wave of the polarization in a direction perpendicular to the sheet rolling direction. Then, the mechanical strength of the thick steel sheet 2 can be obtained by comparing the speed ratio of the transverse wave VL/VC with the relation between the previously obtained speed ratio of the transverse wave and mechanical strength. Thus, the averaged mechanical character of the entire steel, not only the surface layer of the steel, can be estimated.
