Title: Image forming device and method therefor
Inventor: ASADA HIROYOSHI
IPC: G03G15/11
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To avoide deterioration in printing quality and to enable an excellent transfer in a wider paper range, by changing process conditions in accordance with the surface 10-points average roughness of a recording material. SOLUTION: At the time of transferring a toner image to the recording material 6 from a photoreceptor 2, on which the toner image is formed with a liqiud developer being made so that toner grains are dispersed in a liquid carrier, the process conditions are changed according to the surface 10-points average roughness Rz of the recording material 6. The recording material 6 whose smoothenss is high is in a state where the gap between the surfaces of the photoreceptor and the recording material is filled with the liqiud carrier (a), but in the recording material 6 whose smoothness is low, the gap remains without being filled with the liquid carrier, to prevent the electrophoresis of the toner grains (b). In such a case, squeeze gaps of each color or the rotational speed of a squeeze roller is varied according to the surface 10-piece average roughness Rz of the recording material 6.  In a mat system coating sheet for instance, the squeezing gap is widened or the circumferential speed of the squeezing roller is reduced to make the amount of the liquid carrier on the photoreceptor large.

Title: Fluid sealing type active vibration control device
Inventor: TANAHASHI HIROAKI
IPC: F16F13/10
Filed: 1998-12-22
Abstract: PROBLEM TO BE SOLVED: To enhance vibration control capability by increasing transferred vibrating force to a main fluid chamber for an active vibration control device obtaining an active vibration control effect by transferring a pressure fluctuation generated in a sub fluid chamber to the main fluid chamber through an orifice passage by air-vibrating an exciting plate. SOLUTION: Multiple mutually independent vibrating plates 52, 54 are provided on an acting air chamber 58. The individual vibrating plates 52, 54 structure walls of a sub fluid chamber 74. Since the overall area of the vibrating plates 52, 54 is secured advantageously over a case where a single vibration plate is provided on a wall of the acting air chamber 58, the pressure change in the acting air chamber 58 is reflected more effectively to the sub fluid chamber 74, and also to a main fluid chamber 30, thereby increasing the overall vibration control characteristic of a vibration control device.
