Title: Transducer supporting device
Inventor: MATSUBARA KENICHIRO
IPC: G11B21/21
Filed: 1987-03-23
Abstract: PURPOSE:To facilitate the stable holding of a gap between an air, bearing, slider and memory disk by taking the value (aspect ratio) of C/D in the case of taking the flange height as D and the width of the flat part of the beam part for loading as C more than three on whatever cross section of the beam part for loading. CONSTITUTION:The beam part 11 for loading is composed of the upstream side flange 14a and downstream side flange 14b made by bending a flat part 13 and its both edges. And in order to take the aspect ratio more than three at least on whatever cross section of the beam part 11 for loading the heights of the flanges 14a, 14b are lowered according to going to the tip from the tip vicinity of the beam part 11 for loading. The eddy separated from the upstream side flange 14a edge is therefore destroyed prior to reaching the downstream side flange 14b and the width of the following stream becomes smaller and the vertical asymmetry becomes stronger, so the fluid force is reduced and becomes irregular. The stable floating can thus be easily executed.

Title: Electrophotographic recorder
Inventor: MIURA TOMOHIRO
IPC: G03G15/00
Filed: 1987-03-23
Abstract: PURPOSE:To prevent generation of disturbance in image and jam, etc., in a transfer position by providing a roller pair for guiding a recording medium to the transfer position between a resist means and the transfer position. CONSTITUTION:The roller pair for guiding the transfer position is so disposed that axial centers 31a, 32a of an upper roller 31 and a lower roller 32 are respectively positioned on both sides of a drum 1 in the transfer position with the tangential direction S-S' thereof in-between ad that the line connecting both the axial centers 31a, 32a is nearly orthogonal with the tangential direction S-S' of the drum. The recording medium after the medium is led out of the roller pair 20 is, therefore, automatically guided linearly along the tangential direction of the roller even if the resist roller pair 20 is disposed in any position. The recording medium is thus exactly and surely introduced to the transfer position. Even if the recording medium is bounced up by the resist roller pair 20, such bouncing is blocked by the guide roller pairs 31, 32 and, therefore, the disturbance in the toner image on the peripheral face of the drum 1 arising from the bouncing-up is prevented.

Abstract: PURPOSE:To shorten start-up time by opening an intercept valve according to such opening characteristics that the intercept valve begins to open at bias value smaller than the bias value determined beforehand while turbines are idling for starting. CONSTITUTION:A steam governor valve 14 having bias value for biasing the beginning of the opening of an intercept valve 18 from the beginning of the opening of the steam governor valve 14 while very hot turbines 16, 19, and 20 are idling according to flow control signals and the intercept valve 18 are interlockingly opened and closed according to each opening characteristic. At this moment, the intercept valve 18 is opened according to the opening characteristics which begins to open at a bias value smaller than the bias value determined beforehand while the turbine 15, 19, and 20 are idling before starting. In addition, the opening degree of the intercept valve 18 is made to accord with the opening characteristics, while it is very hot, at the specified turbine speed. Since in the case where the temperature of a medium pressure turbine 19 is low, the flow rate of steam can be increased due to this constitution, the turbine is sufficiently warmed up for shortening start-up time.
