Title: Method for recording multicolor image
Inventor: TASHIRO JIYUNICHI
IPC: G03G13/01
Filed: 1984-02-08
Abstract: PURPOSE:To prevent disturbance of a toner image due to magnetic carrier particles different in diameter and to solve the problem of exchange of a developer by using multicolor developers each composed of a mixture of a nonmagnetic toner and a magnetic carrier similar in particle diameter to said toner, and using said carrier in common for different color developers. CONSTITUTION:The surface of a photosensitive drum 1 is uniformly electrostatically charged with an initial charger 2 to a prescribed potential VSO, and exposed to the light of the first color image with an exposure means 3 to attenuate the exposed parts to potential Vk1 and to form a latent image 21. A red toner image 22 having Vt1 is formed by mixing a red nonmagnetic toner with a magnetic carrier similar in particle diameter to the toner, applying developing bias potential VB1, and developing the latent image with the binary magnetic brush developer thus prepared in a developing device 4. Then, a black toner image 24 is formed by recharging the drum 1 with a recharger 5, exposing it to the second black image light, using a developer of a mixture of the magnetic carrier and a black nonmagnetic toner similar in particle diameter to the carrier, and developing the latent image with a developing device 7. As a result, problems of disturbance of an image due to the magnetic carrier particles different in diameter, exchange of the developer, etc., can be solved.

Title: Material testing machine
Inventor: MATSUBARA TERUTSUGU
IPC: G01N3/38
Filed: 1998-02-04
Abstract: PROBLEM TO BE SOLVED: To obtain a material testing machine in which a displacement feedback control operation and a load feedback control operation are performed stably even when a displacement to be controlled and a load to be controlled are small when a test piece is loaded by a motor-driven actuator. SOLUTION: A motor-driven actuator 2 generates a thrust F with reference to a driving signal (i) which is input. When a feedback control operation is performed only by the deviation between the displacement, of a test piece, detected by a displacement sensor 31 and a target displacement, a feedback system becomes a resonance system and a test cannot be made with good accuracy when a displacement is very small. Then, the displacement, of the test piece, detected by the displacement sensor 31 is used as a major loop, the deformation speed, of the test piece, detected by a speed sensor 32 is used as a minor loop, and the feedback control operation is performed. The feedback system becomes a stable system, and a dynamic characteristic is improved.

Filed: 1996-01-18
Abstract: PROBLEM TO BE SOLVED: To stabilize the output of a resonant switching power unit by using an inexpensive PWM control IC by using a variable inductive element and fixing the switching frequency of the power unit. SOLUTION: The PWM-1 circuit 201 of a PWM circuit 2 for controlling output voltage is connected to a switching element S1 and the PEM-2 circuit 301 of a PWM circuit 32 for controlling resonance frequency is connected to a switching circuit Sr. The capacitance of a capacitor Cr and the inductance value of a main winding Lr are set in accordance with the longest on-time of the switching element S1. Therefore, when the duty ratio of a signal Vpwm changes in accordance with voltage fluctuation, the duty ratio of another signal Lpwm also changes and the resonant condition can be controlled in accordance with the on-time of the element S1. Consequently, the switching frequency of the element S1 can be fixed and the load can be reduced at the time of taking a countermeasure against EMI.
