Title: Rotation transmitting mechanism for sleeve roll
Inventor: NAGAI TAKASHI
IPC: F16C13/00
Filed: 1981-11-10
Abstract: PURPOSE:To prevent a sleeve from occurrence of breakage or crack by a method in which the difference between the width of the key grooves on both ends of the sleeve connected to a shaft and the width of keys is caused to be larger than the difference between the internal diameter of the sleeve and the external diameter of the shaft. CONSTITUTION:The internal diameter of ceramic sleeve 2 which is connected to the external circumference of a shaft 1 is caused to be larger than the external diameter of the shaft 1 by D. The keys 7 are fitted into the key grooves 4 equipped on both ends of the sleeve 2, and the difference E between the width of the key groove and that of the key 7 is caused to be larger than said difference D. The force acting on the key 7 and the key groove 4 is decreased, thereby preventing the sleeve 2 from the occurrence of the breakage or crack.

Filed: 1984-08-31
Abstract: PURPOSE:To prevent a shift in transfer position and perform efficient fixation by providing driving motors for a photosensitive drum and a fixing roller in independently of each other and switching the position relation between the both according to the length of transfer paper. CONSTITUTION:The motor M1 for the rotary drum and the motor M2 for the heat roller 17a are provided independently of each other, and their motor speeds are controlled through a motor speed control circuit 23 according to the length of recording paper. The length of the recording paper is detected by a recording paper size sensor 20 and a decision circuit 20. When the recording paper length B is equal to or larger than the distance A from a separation position to a fixation position, a transfer speed V1 is equalized to a fixation speed V2 and when the length B is smaller than the distance A, switching is so performed that V1>V2. Consequently, the transfer paper is never suppressed with the speed of the heat roller, so a shift in transfer position is prevented and efficient fixation is performed.

Abstract: PURPOSE:To obtain recording and reproducing of a high quality by a laser of a low output by controlling an amplitude of a recording signal by an AGC circuit, supplying it to a laser driving circuit, making the center of an output light of the laser match a threshold power of a disk, and outputting it. CONSTITUTION:An AGC circuit 17 controls an input recording signal of an input terminal A by a position detecting signal (j) of a D/A converter 16, so that it becomes smaller toward the outside circumference, outputs it from a terminal G, and supplied it to a semiconductor laser driving circuit 1. In the driving circuit 1, a photoelectric converter PD detects a part of an output light of a semiconductor laser LD, generates a corresponding potential in a K point, and controls an output power of the laser LD so as to become constant. A reference of this control is determined by the potential of the K point, and a TRQ10 and resistances R11, R12 change the potential of the K point by a voltage inputted to a terminal J. Accordingly, a base voltage of a TRQ11 is varied and a forward current I is varied. Also, said recording signal is inputted to a terminal I, and in accordance with it, the laser output light is modulated. In this way, the potential of the K point is controlled so that the output light of the laser LD becomes a threshold power of a recording material on the whole surface of the disk.
