Abstract: PURPOSE:To surely obtain a measuring point with high efficiency regardless of the curvature of a peculiar line set on a processing line, by performing the copying measurement of said peculiar line with weaving by a sensor head based on the curvature, the pitch and the weaving width of the peculiar line. CONSTITUTION:A peculiar line is provided on a processing line of a work and an optical sensor head 20 is attached at an arm tip part 10a of a processing machine main body 10. A copying measurement arithmetic part 40 gives the copying weaving point based on the coordinates of an intersecting point between an optical spot and the peculiar line. At the same time, a CPU of the part 40 calculates the pitch and the weaving width in response to the curvature of the peculiar line. If the calculated pitch is set out of a prescribed range, the pitch is set at its upper or lower limit value so that the pitch is limited within a prescribed range. Based on this pitch, the weaving width is calculated. Thus it is possible to surely obtain a measuring point with high efficiency regardless of the curvature of the peculiar line.

Title: Outgoing call restriction and detection system
Inventor: ZAMA TOMIO
IPC: H04Q3/555
Filed: 1980-03-24
Abstract: PURPOSE:To avoid the ineffective processing in an early time from the detection of outgoing call to the channel block, by controlling the subscribing line monitor scanner if outgoing lines are all in use and avoiding to detect the calling of other subscribers located in the switch. CONSTITUTION:Even if the subscriber telephone set 1 makes outgoing call, when the primary switch outgoing lines are all in use, since no vacant channels are selected, a series of processing from the detection of outgoing call to the selection of channels is made ineffective. The state of usage of the primary switch outgoing lines is monitored in a given period and if they are all in use, the signal distributor (SD)17 is controlled and the SD relay 15 is driven to open the SD contact 14. With this state, if call is made from the subscriber telephone set 1, the line relay contact 13 is closed or the SD contact 14 is open, then the call is not detected, allowing ineffective processing.

Title: Accelerated evaluating method for soft error
Inventor: MATSUMOTO MASATOSHI
IPC: G01R31/26
Filed: 1992-02-24
Abstract: PURPOSE:To accurately perform evaluation even for an accelerated soft error evaluation by the irradiation with alpha-rays exceeding a dose at a usual time by directly connecting a silicon substrate to an external constant potential part to fix the potential of the silicon substrate constant. CONSTITUTION:A silicon substrate 2 is directly connected to an external constant potential part 18 to be held to normal potential V0. That is, the potential of the substrate 2 originally becomes the internal generated potential V2 thereof and the substrate 2 is normally operated but, by the irradiation of alpha-rays exceeding a dose at a normal time, a large amount of holes (h) generated by the irradiation with alpha-rays are drifted to the substrate 2 and, as a result, the potential of the substrate 2 fluctuates. Therefore, by directly connecting the substrate 2 to the constant potential part 18, the fluctuation of the potential of the substrate 2 is prevented. In this case, the potential V0 of the constant potential part 18 is set to a value equal or near to the internal generated potential V2 of the substrate 2 at the time of normal operation.

Filed: 1980-03-24
Abstract: PURPOSE: To obtain sludge having good precipitating and dehydrating properties by quickly adding and mixing a neutralizer containing slaked lime in the acid washing waste water of steel materials.  
     CONSTITUTION: A neutralizer containing slaked lime is quickly added and mixed in acid washing waste water, where mixing and dispersion are finished in a short time before the gel of hydroxides is separated out. Since the slaked lime particles are uniformly dispersed in waste water, hydroxides are formed on the surface of individual slake lime particle, and the formed hydroxides are separated by the mutual collision of the particles due to stirring under such a condition, a silty and blackish green-colored sludge having good precipitating and dehydrating properties, but not in stable gel state, can be obtained.
