Title: Electrophotographic picture stabilizing method
Inventor: NAKAMURA ISOJI
IPC: G03G15/04
Filed: 1982-01-16
Abstract: PURPOSE:To make a good constant continuous pictures formation possible, by changing the strength of exposure or charging for formation of a latent image in accordance with the change of the surface potential of a photoreceptor which is generated according to the number of continuously formed copies. CONSTITUTION:In case that images are formed repeatedly in a high speed, the potential of the surface of the photoreceptor tends to rise, and the image density becomes higher according as the number of formed copies is increased. This inclination cannot be resolved by dimming of a single time constant. Therefore, an original picture exposure means 14 is controlled by an original picture exposure controlling means 30. For example, in a graph where the number of continuously formed copies is indicated on the axis of abscissas and the voltage of an original picture exposure lamp which is the original picture exposure strength to be given by the expsoure means 14 is indicated on the axis of ordinates, the voltage of the lamp is changed in accordance with an exponential function curve (a), and the voltage of the lamp is changed in accordance with a curve (b), which is connected to the curve (a) and has a time constant longer than that of the curve (a), after the curve (a) is saturated approximately.

Title: Rotary drum device
Inventor: HIRAO MASAKI
IPC: G11B5/02
Filed: 1992-01-16
Abstract: PURPOSE:To improve the workability by bringing a stator of a motor into direct contact with a fixed side rotary transformer in order to utilize the rotary transformer for positioning at the time of fixing the motor which is required for its positioning. CONSTITUTION:A rotary side rotary transformer 3 is fixed to a rotary side cylinder 7, and the rotary side rotary transformer 3, the fixed side rotary transformer 2, the stator 4 of the motor and a rotor 5 of the motor are arranged in order from a rotary shaft 1 fixed in the center toward the outer side. By this method, the stator 4 of the motor and the fixed side rotary transformer 2 can be brought into direct contact with each other without providing a gap between them, and the positioning of the stator 4 of the motor can easily be performed by the fixed side rotary transformer 2. Consequently, since the motor is assembled without a reference of an outer diameter of an unstable shield plate 8 but with a reference of the outer circumferential surface of the fixed side rotary transformer 2, the accuracy is improved, and also the workability is promoted.

Abstract: PROBLEM TO BE SOLVED: To facilitate assembly and at the same time to reduce magnetic flux leakage through suppressing a spread in the external-diameter direction of the protrusions of first and second rotor cores by a third rotor core for improving the resistance against centrifugal force, and at the same time by retaining a magnet in the third rotor core. SOLUTION: A rotor has a laminated core 122, where an electromagnetic steel plate has been laminated, pole parts (protrusions) 123a and 123b which extend radially, field coil winding 124 which are wound and fitted, and/or a shaft 125. Although the outer periphery of a rotor 120 constitutes N and S magnetic poles by a magnet 128 inserted into the rotor 120, the N-magnetic pole is short-circuit through a pole part 123a which is engaged to an N-magnetic pole side groove, iron cores 121a and 121b, and a pole part 123b engaged to an S-magnetic pole side groove. As a result shunting, short-circuiting, and reducing effective magnetic flux to a stator side are realized.

With a pulling rod 2, the jig 1 is loaded into and unloaded from the treating tube 6 installed in a heating apparatus. In this case, if a cooling region 6' is provided on an extension of the treating tube 6, then, the semiconductor substrate 4'' are still located in the cooling region 6' even in a state wherein the first cap 3'' has not yet reached the end of the cooling region 6'. Therefore, if oxygen exists, the substrates 4'' do not react with oxygen. Accordingly, no oxide is formed on the semiconductor substrate surfaces.

Title: Semi-chord and different speed driving mechanism
Inventor: ARIMA TOKUE
IPC: F16H37/06
Filed: 1981-01-19
Abstract: PURPOSE:To permit exact operation of a driving mechanism by a necessary power suitable to the magnitudes of loads by using a system in which the continuous output of a motor can be alternately switched to a high-speed transmission mechanism and a low-speed transmission mechanism by the ON or OFF operation of an electromagnetic clutch. CONSTITUTION:When a low-speed transmission mechanism L is in connected state nad a rotator 21 begins to turn from the point (a), just before the point (c), a detector 34 is turned ON by a dog 32. By this, the magnetism of the first electromagnetic clutch 7 is erased and a transmission mechanism 2 is switched to quiescent state, while the second electromagnetic clutch 17 is excited and a high-speed transmission mechanism H is connected. On the principle, the rotator 21 is moved from the point (b) at which low-speed rotation is ended to high- speed rotation, and just before the point (a), the detector 33 is turned ON by a dog 82. As a result, the transmission mechanism is continuously operated from high-speed side H to low-speed side L, and the rotator 21 is likewise turned continuously while being switched to low-speed and high-speed sides.
