Title: Fm detection circuit
Inventor: MIURA MASAMI
IPC: H03D3/02
Filed: 1985-11-06
Abstract: PURPOSE:To apply phase locked type FM detection while using a voltage controlled oscillator by branching an input signal into two, inputting the one to a phase comparator via a transmission circuit whose transmission characteristic is varied, inputting the other directly and using a signal filtering the output of the phase comparator so as to change the characteristic of said transmission circuit. CONSTITUTION:The input is inputted to a phase comparator 103a via the 1st signal transmission circuit 101 from a terminal A and inputted to the phase comparator 103a via the 2nd signal transmission circuit 102. The capacitance of varactor elements D1, D2 is varied by a signal voltage inputted to a resistor R3 in the 2nd signal transmission circuit 102 to vary the frequency transmission characteristic. The output of the phase comparator 103a is inputted to a low- pass filter 104a and the output is fed back negatively to the 2nd signal transmis sion circuit 102 to compress the phase difference of the two inputs.

Title: Sensorless driving circuit of brushless dc motor
Inventor: TSUCHIMOTO RYOICHI
IPC: H02P6/182
Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To provide a sensorless driving circuit of a brushless DC motor which enables the stable driving of the brushless DC motor even if a load is suddenly changed and a power supply voltage is suddenly changed in a low speed and high load operation. SOLUTION: The level of a commutation command is switched from HIGH to LOW in an intermediate zone between 1st and 2nd current increase regions after the command is generated. By this switching, an analog switch AS1 is turned off. A voltage value (instantaneous output) of a current detection circuit 4 immediately before the turning-off is held in a sampling circuit 5, amplified approximately 1.6 times by an amplification circuit 6 and outputted to a target value control circuit 8 through a priority circuit 9. As the target value control circuit 8 keeps a commutation target voltage higher than a commutation target wave peak value at every commutation command, the commutation command is prohibited. A commutation target voltage outputted from the target value control circuit 8 is outputted to a commutation command circuit 10.  If a voltage value outputted from the current detection circuit 4 reaches a value certain times of the output voltage value of the sampling circuit 5, the commutation command circuit 10 outputs one-shot pulse to a numerical circuit 13 and the commutation of a brushless DC motor 51 is practiced by a distribution circuit 14 and an inverter circuit 3.

Title: Rotation transmitting system
Inventor: TAMURA CHIKATOMO
IPC: F16H49/00
Filed: 1990-09-19
Abstract: PURPOSE:To realize accurate and stabilized torque control and engaging/ disengaging of clutch on the output side by displacing a shutter, made of ferromagnetic material, in the gap between magnetized parts of each rotary body. CONSTITUTION:When a shutter 10 is displaced gradually, an opening 14 shifts from rotary bodies 4, 8 and the magnetic force of lines, existing between magnetized parts 3, 7, is blocked gradually by means of the ferromagnetic shutter 10 and thereby the torque of a rotary shaft 5 decreases correspondingly and the rotary shaft 5 stops when the torque decreases below a load torque. Since the torque of the rotary shaft 5 on the output side can be regulated smoothly and continuously according to the displacement amount of the shutter 10 while furthermore the rotary bodies 4, 8 are arranged in non-contacting state, torque control is scarcely subjected to the surface conditions of the rotary bodies 4, 8 or the ambient environmental conditions and thereby high accuracy can be sustained for a long term.

Title: Recorder
Inventor: KANEKO MASANORI
IPC: H04N1/23
Filed: 1988-10-03
Abstract: PURPOSE:To enable a smooth and secure clutch operation by rotating a motor reversely before switching a clutch, at the time of switching the clutch after rotating the motor by a required amount. CONSTITUTION:A clutch 12 is capable of such a switching is to transmitting a torque of a feeding motor 11 selectively to either one of two members 15, 16. A clutch solenoid 13 is turned ON during a sub-scanning period P for feeding a recording paper 2 by rotating a platen 1. The solenoid 13 is turned OFF during a main scanning period C for rotating a controlling rod 18. The motor 11 is rotated reversely by a slight amount before the solenoid 13 is switched OFF, that is, before time T9 at which a driving voltage for the solenoid 13 is lowered to an OFF state. Therefore, when friction is increased due to biting at each torque-transmitting part under rotation of the motor, the biting can be easily released, and the clutch can be switched securely and smoothly.

Abstract: PURPOSE:To form a high quality image at high speed and over a long term by performing a non-contact development process using a one-component type developer via the application of DC and AC superposed development bias to a latent image on a photoreceptor containing specified perylene pigment. CONSTITUTION:An electrostatic latent image is formed via exposure on the photoreceptor of a conductive carrier having a charge generation layer and a charge transfer layer containing the perylene pigment expressed by the formula I and/or II. In the formulae I and II, Z stands for a group of atoms required to form a replacement or non-replacement aromatic ring. Thereafter, development bias with DC and AC bias superposed is applied to the electrostatic latent image and the image is developed in a one-component type developer by using non-contact development method, thereby forming a toner image on the photoreceptor. Thus, an image can be formed at high speed, using a photoreceptor having high sensitivity characteristics, and a photoreceptor flaw due to carrier deposition, or an image defect such as a white and dark spot can be eliminated. Also, an image having clear fog can be provided. Furthermore, a high quality image can be provided stably, even when the image is repeatedly formed over a long term.
