Abstract: PURPOSE:To prevent deflection of a car body due to rapid brake during running on a road surface where a friction factor is different between the right and the left by reducing the brake force of front wheels through control of the feed working fluid pressure of a working fluid feed passage on the front wheel side when a given rapid brake state is detected from the change of the working fluid pressure of rear wheels. CONSTITUTION:An oil pressure is generated from a master cylinder MC according to operation of pedalling operation of a brake pedal B and fed through oil pressure feed passages 2F and 2R to brake mechanisms for front wheels 3R and 3L and rear wheels 4R and 4L. When, for example, the left rear wheel 4L is brought into rotation about to be locked, an ABS device 5 is worked, the oil pressure of the oil pressure feed passage 2R on the rear wheel side is repeatedly fluctuated and a lock is prevented from occurring. In this case, on a brake control mechanism 6, when the ABS device 5 is started to control and an oil pressure fed to the rear wheels 4R and 4L side is reduced, a brake piston 17 is moved to the first liquid chamber 18 side, the volume of a second liquid chamber 19 is increased to decrease the feed oil pressure of an oil pressure feed passage 2Fb on the front wheel side is reduced, and the brake forces of the front wheels 3R and 3L are relatively reduced.

Abstract: PURPOSE: To keep boiler function even when coke can not be cut down from lower part and to prevent the residence of gas in a furnace, by a method wherein in a cooling gas-forced circulation system the downstream side of a waste-heat boiler is connected to the top part of a furnace, and a by-pass pipe line is provided which is opened as the occasion demands.  
     CONSTITUTION: The downstream side of a waste-heat boiler 25 is connected to the top part of a quenching furnace 25, and a by-pass pipe line 43 is provided which is opened as the occasion demands. When the supply of cooling gas becomes impossible by a trouble, an on-off valve 45 is adjusted and an on-off valve 44 is opened. The cooling gas is passed through the by-pass pipe line 43 into a duct 42, and then into the top part 38 of the furnace. Then the gas is contacted with red hot coke which is placed within a prechamber 25A and is not quenched under normal conditions. The gas heated to a high temperature is forcedly recycled through a throughhole 30, a circular gas 29, a duct 32, a waste-heat boiler 31 and a blower 34 to the by-pass pipe line 43. In this way, the same quantity of heat as during normal operation can be supplied to the waste-heat boiler 31. Since the recycling of the gas is continued, the prechamber is prevented from being filled with combustion gas.

Title: Image forming device
Inventor: ETO KOICHI
IPC: G03G15/08
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To improve a gradation characteristic by preventing the occurrences of so-called surface staining and the paint out of white clots by setting a developing bias value applied to a developing sleeve at the half of surface potential at the non-image part of an image carrier. SOLUTION: Developing bias having the same polarity as the surface of the image carrier 1 is applied to the developing sleeve 4c by a high voltage source 4d. The voltage value of the developing bias is a value between the potential of the non-image part and that of the image part. Thus, an electric field (developing electric field) in a direction where one-component type developer 13 on the developing sleeve 4c is stuck to the image carrier 1 is generated at the image part on the surface of the image carrier 1. The intensity of the developing electric field is shown by the absolute value of a difference in the potential of the image part and a developing bias value.  On the other hand, the electric field to make the one-component the developer 13 go from the surface of the image carrier 1 to the developing sleeve 4c is generated at the non-image part on the surface of the image carrier 1. The voltage value of the developing bias is set about the half of the potential of the non-image part of the image carrier 1, so that an excellent gradation characteristic is obtained.
