摘要:
In a xerographic copying apparatus of the invention, a control unit to control a stepping motor to cause rotation of an image supporting body to synchronize with running of a transfer medium performs acceleration and deceleration of a rotation speed of the image supporting body while the image supporting body is rotating in a reverse rotation direction, and accordingly, paper powder or foreign matter accumulated in a cleaning mechanism to clean a developer on the image supporting body can be collected, the occurrence of abnormal noise is prevented, and a definite amount of reverse rotation of the image supporting body can be realized while avoiding damage of the image supporting body due to a speed difference between the image supporting body and the transfer medium.

摘要:
An apparatus in which ultrasonic vibrations or acoustic emissions are detected includes a rotating shaft 21 having a dressing wheel 31 mounted on one end, and a detection liquid supply unit 41 disposed at the end face of the wheel and/or shaft so as to form a gap S therebetween and to supply detection liquid toward the rotational center of the wheel to form a detection liquid membrane in the gap. An AE sensor 43 is provided integrally with the detection liquid supply unit and detects the ultrasonic vibrations or acoustic emissions of the wheel and/or shaft through the detection liquid membrane formed in the gap.
摘要:
A digitized quasi-phase synchronous phase detecting signal of the PSK signal is used to generate digitized quasi-synchronous phase detecting signal phase-corrected by phase correcting data and a first phase display data indicating the phase of the carrier of the PSK signal is generated from the phase-corrected digitized quasi-synchronous phase detecting signal. Alternatively, the digitized quasi-synchronous phase detecting signal of the PSK signal is used to generate second phase display data indicating the phase of the carrier of the PSK signal and third phase-corrected phase display data is generated from the second phase display data. The first or third phase display data is used to generate fourth phase display data indicating the phase assigned to the code of the PSK signal and a decoded digitized code is generated from the fourth phase display data. When signal presence display information is in its state to indicate the amplitude of the PSK signal is larger than a predetermined threshold, the frequency and phase of the carrier of the PSK signal are predicted using their estimated frequency and phase based on the first or second and fourth phase display data. When the signal presence display information transitions to its state to indicate that the amplitude of the PSK signal is smaller than the predetermined threshold, the frequency and phase estimated until then are used to predict the frequency and phase of the carrier of the PSK signal and phase data in the predicted frequency and phase data is generated as the phase correcting data.

摘要:
Alkyl (or aralkyl) .alpha.-isocyanoacetate is condensed with a trihalogenoacetic aldehyde or its hydrate in the presence of an amine to give trans-4-alkoxycarbonyl(or aralkyloxycarbonyl)-5-trihalogenomethyl-2-oxazoline. The oxazoline compound is hydrolyzed under acidic conditions to give threo-.gamma.,.gamma.,.gamma.-trihalogenothreonine, which is then subjected to catalytic or electrolytic reduction. The above-mentioned reactions can be carried out stereoselectively and threo-threonine is thereby obtained without by-products such as allo-threonine.
