Inventor: NAGASAWA NAOKAZU
IPC: G03G9/083
Filed: 1983-01-11
Abstract: PURPOSE:To obtain a picture with prescribed density by arranging a magnet holding member which incorporates a magnet roll in a nonmagnetic sleeve arranged in a developing container, making the magnet roll and sleeve eccentric, and replacing the developer on the sleeve surface. CONSTITUTION:The nonmagnetic sleeve 7 is arranged in the developing container 4, the magnet holding member 12 is arranged in this sleeve 7, and the magnet roll 23 is arranged rotatably in the magnet holding member 12. The axial center of the magnet roll 23 is made eccentric with that of the sleeve 7. Consequently, the part where magnetic force is weak is formed on the surface of the sleeve 7 and a scraper is provided thereto to scrape easily the developer sticking to the surface of the sleeve 7 after development. Therefore, a fresh developer containing sufficiently mixed toner is stuck newly to the part where the developer after development is removed from the surface of the sleeve 7. Further, the part where the magnetic force is weak is utilized, so the power for scraping off the developer may be small. Furthermore, there is no developer which rotates while sticking to the sleeve surface as usual, so the picture with the prescribed density is obtained.

Title: Recording medium for thermal rheography
Inventor: YAMAGUCHI HIROYUKI
IPC: B41M5/382
Filed: 1987-01-12
Abstract: PURPOSE:To obtain recording quality with clearness and high resolution, by providing at least one thermal isolation layer capable of being melted or thermal ly broken down when being heated, on the surface of a recording paper. CONSTITUTION:A color developer 15 is isolated by a thermal isolation layer 16, so that mere adhesion of an ink 9 to the thermal isolation layer 16 does not enable a colorless dye 14 contained in the ink 9 to make contact with the color developer 15, and a color forming reaction does not take place. Only when the layer 16 is melted by heating and the ink 9 is adhered to the layer 9, the color developer 15 on a recording paper 2 makes contact with the color less dye 14 in the ink 9 to start a leuco color developing reaction, whereby a visible image is formed. Even when the ink 9 is adhered to the paper 2 in a surplus region, isolation of the color developer 15 and the colorless dye 14 from each other by the layer 16 in the region can be maintained by not heating the region, so that additional color development does pot occur even when the recording paper 2 is left to stand for a long time. Also in thermal rheography using a colored dye, a surplus of ink 9 adhered to the recording paper 2 can be wiped off by a cleaning roller or a felt, whereby a clear image can be obtained.

Title: Vehicle turn controller
Inventor: FUJITA KOZO
IPC: B62D6/00
Filed: 1995-01-12
Abstract: PURPOSE: To make a turn limit point proper at all times and to improve turn performance by changing the setting of a control limit point depending on whether a turn controller is mounted on a vehicle on which the other vehicle turn controller is mounted or not, or depending on whether the other turn controller is operating or not when it is mounted on the vehicle. CONSTITUTION: A rear wheel steering angle controller ARS and a vehicle behavior stability controller VSC are mounted on a same vehicle. While the controller VSC is operating, a transistor 154 is shut off, current flows into a resistor 142, and voltage of an input terminal 140 of a CPU32 becomes high level, increasing a control limit value. Moreover, when VSC is not operating, the transistor 154 conducts electricity and voltage becomes low level, reducing the control limit value. When the limit value is high, an operation region of ARS is B region, namely, the whole linear region and non-linear region among cornering characteristics, and when the limit value is low, it is only C region and cornering characteristic becomes a turn limit before the nonlinear region to facilitate correction steering.
