Title: Developing device
Inventor: KOGA YOSHIRO
IPC: G03G15/09
Filed: 1990-03-09
Abstract: PURPOSE:To maintain the stable carrying state of toner and a developing state by making the surface roughness of a developing roller smaller than the minimum magnetic reversal interval of a magnetic field generation layer and smaller than the volume average grain size of one component magnetic toner. CONSTITUTION:The developing roller is obtained by forming an elastic layer 22 whose main component is elastic resin on a substrate 21, forming the mag netic field generation layer 23 on the elastic layer 22 and forming an electrically conductive layer 24 on the magnetic field generation layer 23. Since the surface roughness of the conductive layer 24 being the contact surface of the developing roller and the toner 25 is made sufficiently smaller than the minimum magnetiz ing and inverting interval, the thin layer of the toner 25 does not become ununiform by the surface roughness of the developing roller, and it becomes equal to or under the volume average grain size of the toner 25 and desirably to the extent of 1/2 of the volume average grain size, so that the toner 25 is prevented from being fixed on the conductive layer 24 and the contact area of the toner 25 and the conductive layer 24 is sufficiently secured. Thus, the triboelectric charge performance of the toner 25 is improved and stably maintained.

Title: Production of exterior decorative board
Inventor: YOSHIKAWA MAKOTO
IPC: B05D1/28
Filed: 1979-05-12
Abstract: PURPOSE: To provide pattern close to natural wood grain in patterning of exterior decorative board such as cement plate by a method wherein the surface of the board is provided with groove shaped depressions coated with undercoat, and the flat plate part other than the depressions is applied with three-dimensional stripes and different color coating, using a striping roll.  
     CONSTITUTION: The first color undercoating is applied to the surface of a cement plate 1 having reinforcement layer 3 such as synthetic resin and groove shaped depressions 2. Before the undercoating is cured, striping operation and the second color coating is applied on the area other than the depressions of the plate 1. In this manner, the top 71 of the groove shows mixed color of the first and second colors, the bottom 72 of the groove shows the second color, and the depressions 2 is given the first color layer 21 because the area is not given the second coating. The process thus provides a board having natural wood grain pattern.

Title: Opening/closing speed control device for valve
Inventor: NAKAJIMA TAKEO
IPC: F15B9/07
Filed: 1992-02-13
Abstract: PURPOSE:To enlarge a variable range of operating speed of an actuator by providing such a positioner that controls displacement amount of the actuator so that it becomes fixed functional relation with respect to an optional input signal, and a throttling means connected just upstream of a chamber in the duct line of that input signal. CONSTITUTION:When control pressure is supplied to a control pressure supply duct line 10 through a solenoid valve 9, pressure inside the duct line rises and specified control pressure acts upstream of a throttle valve 8. Control air is restricted by the throttle valve 8 in its flow rate, transmission speed is slowed down by volumetric effect of a cushion chamber 7, and the rising speed of the pressure of the control pressure input port 4 of a positioner 3 becomes slow. Accordingly, operating speed of a pneumatic actuator 1 whose displacement is controlled in response to an input signal is also slowed down, and opening speed of an on-off valve 2 becomes slow. Although the pressure existing upstream of the throttle valve 8 immediately drops to the atmospheric pressure when the duct line 10 is opened to the atmosphere by the solenoid valve 9, pressure in the port 4 gradually drops by the action of the chamber 7 and the throttle valve 8, and the closing speed of the on-off valve 2 becomes slow. From the foregoing, control range of valve opening/closing speed can be enlarged.
