Title: Positive or reverse revolution change-over method of voltage type thyristor-motor
Inventor: KOUNO KIMIO
IPC: H02P7/00
Filed: 1978-05-17
Abstract: PURPOSE: To inhibit inrush currents to a thristor-motor, by inserting a delay circuit functioning only when change-over between a current control circuit for comparing current commands and current feedback signals and an automatic pulse phase shifter.  
     CONSTITUTION: A delay circuit 20 is mounted among a current control circuit ACR for obtaining deviation between the currents VCB of thyristor transducers 25∼28 and current commands VCP and automatic pulse phase shifters 21, 22 for controlling the ignition phase of thyristors 25, 27 at the positive side or ones 26, 28 at the negative side in response to the output ΔVC 1 . The delay circuit 20 is provided with the functions that put out voltage ΔC 2  near zero regardless of the output ΔVC 1  from the current control circuit ACR during the time when both positive and reverse  transducers are under OFF conditions when said transducers are changed over, and slowly  increase output with time constant beforehand decided so that the output become to the output  value ΔVC 1  from the current control circuit VCR when either of said positive or reverse transducer is in ON. Thus, inrush currents to a thyristor- motor 13 are inhibited when changing over  the transducers, and the generation of torque-ripple is reduced.

Title: Image transfer device
Inventor: IMABAYASHI ARATA
IPC: B41F13/00
Filed: 1993-03-18
Abstract: PURPOSE:To prevent inaccuracy in register, by making, in the case of carrying out transfer by the use of a drive means that drives and rotates one cylinder and by the use of a drive transmission means that synchronously rotates the other cylinder, the effective periphery of the synchronously rotated cylinder longer than that of the driving cylinder, and by setting the difference within the specific value. CONSTITUTION:In the case of driving a transfer cylinder 1 by means of a motor 33 and synchronously rotating an impression cylinder 8 via gears 31 and 30, the effective periphery of the impression cylinder 8 is-made longer than that of the transfer cylinder 1. In this case, torque produced by friction in the nip part is small compared to an amount that the gear 31 rotates. As a result, the impression cylinder 8 is caused to rotate by forcibly slipping the nip part by the driving force transmitted from the gear. At this time, in the case where the effective periphery of the impression cylinder 8 is considerably large compared to that of the transfer cylinder 1, an amount of slip in the nip part becomes large to exert an unnatural force to an image formation material and this adversely affects accuracy in register. Therefore, the effective periphery difference is set to as little a 1.0% or less.

Title: Method for controlling heat roller fixing of copying machine
Inventor: KAWAUCHI SHIGEHIRO
IPC: G03G13/20
Filed: 1986-03-19
Abstract: PURPOSE:To remove miscopy by setting up the setting temperature of a fixing roller in a whole image mode higher than that in a non-image part forming mode. CONSTITUTION:The setting temperature of the fixing roller in the whole image mode is set up higher than that in the non-image part forming mode. Namely the non-image part forming mode and the whole image mode can be switched to prevent the generation of jam or temperature rise and the temperature of the fixing roller is set up to about 18 deg.C in the non-image part forming mode and set up to about 195 deg.C in the whole image mode. When the non-image part forming mode is switched to the whole image mode, copying operation is disabled until the temperature of the fixing roller reaches 195 deg.C to suppress the generation of miscopy. Since no jam is generated and fixing also is sufficiently available when the whole image mode is switched to the non-image part forming mode, it is unnecessary to disable the copying operation until the temperature of the fixing roller is dropped to a low temperature and the copying operation can be immediately executed.
