Patent JP-S59194687-A (JP)
Title: Controller of dc motor
Inventor: KOIE KAZUHIRO
IPC: H02P7/28
Filed: 1983-04-18
Abstract: PURPOSE:To enable to correctly discriminate the polarity of a torque by providing a limiter means for limiting the level at a filter of the front stage of a torque polarity discriminator. CONSTITUTION:Since a speed actual value signal detected by a tachometer generator and led to a speed regulator contains a ripple, the output signal of the regulator instantaneously tends to invert the polarity near zero. When this signal instantaneously becomes negative, a regulating amplifier is saturated to the zero holding signal, with the result that a torque polarity signal Tp inputted to a torque polarity discriminator becomes like (b). This signal Tp is limited to a small value by a clamping diode 90D provided in the filter 90 and supplied to a comparator 92. In this manner, a phenomenon for erroneously detecting the inversion of polarity near the zero of the rotating speed can be prevented.

Title: Fan alarm detection system
Inventor: HONDA SHIGERU
IPC: H05K7/20
Filed: 1990-03-20
Abstract: PURPOSE:To improve the processing efficiency of a fan alarm detection system by giving the redundancy to a fan system and inhibiting the production of an instruction signal for the break of a power supply of the system against the abnormality of a fan which is kept within the range of the redundancy. CONSTITUTION:The redundancy is provided to (n) pieces of cooling fans 111-11n so that a device can be work normally even if (m) pieces of these fans (m<n) stop their operations. The alarm detectors 121-12n produce the alarm detection signals when the abnormality is detected in the fans 111-11n. An alarm deciding part 13 instructs a power control part 14 to break the power supply of a system if the abnormality is detected in (m) pieces of fans or more by the alarm detection signals. When the abnormality is detected in (m) pieces of fans or less, the fan actions to be carried out at the time of generating abnormality are instructed based on the fan redundancy constitution. Then the information of an alarm is informed to a system monitoring part which is not shown in the diagram. As a result, the system down frequency due to the abnormality of a small number of fans can be reduced and the system processing efficiency is improved.

Title: Synchronizing signal detector
Inventor: HAYASHI SHINICHI
IPC: H04L7/08
Filed: 1985-04-03
Abstract: PURPOSE:To detect a synchronizing signal with no effect of error by obtaining the auto-correlation with a prescribed one of digital signals for detection of the synchronizing signal in response to the characteristics of errors caused when the information is read and detecting the value larger than a prescribed level for said auto-correlation. CONSTITUTION:A decoder 1 takes notice of only the part ''1'' of a synchronizing signal pattern to obtain an auto-correlation; while a decoder 2 takes notice of only the part ''0'' of said signal pattern to obtain the auto-correlation respectively. Then an OR is obtained between both correlations by an OR circuit 5 through peak detectors 3 and 4. Thus a synchronizing signal can be detected despite an extra error or a missing error. As a result, both extra and missing errors never arise at a time within a synchronizing signal. Therefore a synchronizing signal detector can have the assured synchronization.

Abstract: PURPOSE:To prevent shaking of a channel box and thereby to improve the precision in measurement by a method wherein rollers each of which supports the channel box laterally and can rotate in the direction of insertion are provided oppositely for an upper frame of a measuring apparatus. CONSTITUTION:Rollers 5 each of which supports an inserted square channel box so that it holds the channel box from four sides, can rotate in the direction of insertion and is formed of an elastic material are provided oppositely for an upper frame of a measuring apparatus. The rotating shaft 6 of the roller 5 is slidable in the horizontal direction and a spring 7 follows the dimension of the outside diameter of the channel box and actuates the roller 5 in the opposite direction to the other by a prescribed force so that the channel box can be centered automatically. Since the roller 5 holds down the channel box even when it shakes before it is inserted into the measuring apparatus, according to this constitution, the shake vanishes at the time of measurement of the amount of deformation and the thickness of an oxide film and these can be measured precisely. Since the roller 5 is rotatable, besides, the possibility of damaging the channel box is eliminated.
