Title: Image forming device
Inventor: KOGA YOSHIRO
IPC: G03G15/09
Filed: 1990-03-09
Abstract: PURPOSE:To stably form a high-resolution and high-definition image without having irregularities in a density and with having the excellent reproducibility of a fine line and an isolated dot by specifying both a minimum dot pitch in optical writing to a latent image carrier and the minimum magnetization inverting interval of a magnetic field generating layer. CONSTITUTION:An elastic layer 22 made of an elastic resin as a main component on a substrate 21 such as a shaft, the magnetic field generating layer 23 is formed on the elastic layer 22, and a conductive layer 24 is formed on the magnetic field generating layer 23 to obtain a developing roller. The minimum dot pitch in the optical writing to the latent image is set <= 100(mum), and the minimum magnetization inverting interval of the magnetic field is set <= 500(mum). Thus, the magnetization of a very small pitch is carried out on the thin magnetic field generating layer and the minimum magnetization inverting interval is narrowed, so that an uniform thin toner layer 25 can be formed on the developing roller. Thus, the irregularities in the density caused by the fluctuation of the magnetic field and the thickness of the toner layer are reduced, and a development with the excellent reproducibility of the fine line and the isolated dot is carried out even with respect to a high resolution electrostatic latent image.

Title: Hydraulic circuit
Inventor: YOSHIDA KUNIHIKO
IPC: F15B11/05
Filed: 1981-04-20
Abstract: PURPOSE:To surely control the speed of an actuator independently of the magnitude of the load upon it. CONSTITUTION:A pressure-compensation-type flow control valve 31 is provided in a halfway part of a pipe passage 30 extending from the work ports of directional control valves 4-6 to a tank 29. The flow control valve 31 is regulated by the output pressure of a shuttle valve 28 so that the rate of flow through the valve 31 corresponds to the output pressure of the valve 28 and is independent of the pressure of the work ports of the directional control valves 4-6. For that reason, when an operating lever 15a is turned down rightward, an output corresponding to the changed position is supplied from a pressure reducing valve 19 to shift the directional control valve 4 rightward to expand a hydraulic cylinder 10. At that time, since the rate of flow through the flow control valve 31 corresponds to the output of the pressure reducing valve 19, the speed of the cylinder 10 corresponds to the changed position of the operating lever 15a.
