Title: Plunger solenoid
Inventor: MATSUMOTO MITSUSABUROU
IPC: H01F7/16
Filed: 1979-01-11
Abstract: PURPOSE: To provide the control function for the absorption speed of a moving core by a method wherein a permanent magnet is equipped in a portion of the moving core, detects the traveling speed of the core by measuring the variation of flux density, and dynamically feeds back the results to a control coil.  
     CONSTITUTION: When a driving coil 3 is excited, a moving core 2 is absorbed by the magnetomotive force in the direction shown by an arrow mark. At the same time an electromotive force is generated in a speed detecting coil 7 according to the motion of a permanent magnet 6. This electromotive force is amplified by an amplifier 9, transmitted to a controlling amplifier 10 and generates a controlled coil-driving signal to excite a coil 5. The mangetomotive force induced in the coil 5 is an antiphase vector, its phase is shifted by 180° from that of the exciting coil 3, and backward excites excessively and instantaneously to absorb the core 2 to the set up position. By this way, the absorption force toward the core 2 can be partially and voluntarily controlled during the time from start to end of its absorbing action. When this method is adopted, the touch pressure condition of a piano can be mechanically set up.

Filed: 1981-01-12
Abstract: PURPOSE:To maintain excellent image quality for a long period by providing a control means which precisely controls the quantities of light for discharging corresponding a transferred area and an untransferred area on a photoreceptor. CONSTITUTION:When an original smaller than the size that a photosensitive drum can takes a copy is copied, a transferred area 18 and an untransferred area 19 are formed; a great amount of toner sticks to the untransferred area 19 when an original press plate is not used like a copy of a book, and only a small amount of toner is left in the transferred area 18. For this prupose, shutters 20 and 21 divided corresponding to the size of transfer paper are arranged on the front surface of a discharging lamp 9; when large-sized transfer paper is used, the shutters 20 and 21 are half-opened to perform discharging with a small quantity of light and when transfer paper with smaller size is used, the smaller shutter 21 is opened fullt while the other shutter 20 is half-opened during the discharging. Thus, the optical fatigue of the photosensitive drum is reduced.

Abstract: PURPOSE:To obtain recording quality with clearness and high resolution, by using one of a diazonium salt and a coupler as a constituent of a colored substance, using the other as a constituent of a recording paper, performing recording by bringing the diazonium salt and the coupler into reaction with each other, and irradiating a recorded surface with electromagnetic waves to decompose the diazonium salt left unreacted. CONSTITUTION:Heat generating elements 4 of a perforated type thermal head 6 are energized to generate heat, thereby melting an ink 9. The melted ink 9 passed through ink passage holes 7 to adhere to a surface layer 17 of a recording paper 2. A diazonium salt 16 contained in the melted ink 9 performs a diazo coupling reaction with a coupler 20 contained in the surface layer 17 of the paper 2 to form an image-forming substance. The reaction is accelerated by the heat transferred from the heat generating elements 4 to the surface of the paper 2 and by a guanidine salt 22 and a sensitizer 21. The diazonium salt 16 contained in the surplus ink 9 which is adhered to the surface layer 17 but not subjected to the coupling reaction is photolyzed by UV rays 19 emitted from a UV lamp 18. The image-forming substance formed by the coupling reaction has excellent stability.

Abstract: PURPOSE:To prevent a copy from being stained by coupling a ring-shaped from body by a beam and fitting a cleaning member which cleans nearby members at the periphery of a transfer drum to the beam of the transfer drum wound with a transfer film made of a dielectric. CONSTITUTION:The ring-shaped frame body is coupled by the beam 22 and the cleaning member 14 which cleans the nearby members at the periphery of the transfer drum 20 is fitted to the beam 22 of the transfer drum wound with the transfer film 24 made of the dielectric. The cleaning member 14 can be shifted in its fitting position so that the quantity of abutting on the nearby members is small when image formation is in process and large when it is not in process. Consequently, stains of the nearby members which are arranged nearby the transfer drum 20 such as an entrance shield can be removed at all times and the cleaning member 14 is also cleaned by a transfer drum cleaning device 40, so copies can securely be prevented from being stained. Further, only when the nearby members are cleaned, a fur brush protrudes, so torque variation due to the friction against the nearby member such as the photosensitive body is not caused and no jitter position shift occurs.
