A vehicle suspension system includes a cylinder device provided between a vehicle body member and a vehicle wheel member for the vehicle body member in which suspension characteristics are changed by controlling a hydraulic fluid supply for the cylinder device. A pressure detector detects a hydraulic pressure of the cylinder device for each of the vehicle wheel members, and a warp control unit computes a warping of vehicle body so as to control a hydraulic fluid supply for the cylinder device in a manner such that the warp of the vehicle body is suppressed. The warp control unit is provided with a front pressure ratio computing section for computing a front hydraulic pressure ratio between the cylinder devices for right and left front wheels, and a rear pressure ratio computing section for computing a rear hydraulic pressure ratio between the cylinder devices for right and left rear wheels so that the warp control unit controls the hydraulic fluid supply for the cylinder device based on the front and rear hydraulic pressure ratios. The front pressure ratio computing section produces a value of the hydraulic pressure ratio corresponding to a threshold limit value when the front hydraulic pressure ratio computed in the front pressure ratio computing section is beyond the threshold limit value. An understeer property of the vehicle can thus be obtained in a high lateral acceleration condition.

A vehicle suspension system includes a liquid piston-cylinder device connected between the vehicle body and a wheel. A liquid pump is provided in a liquid passage which connects the liquid piston-cylinder device to a reservoir in which hydraulic liquid is reserved, and feeds under pressure the hydraulic liquid in the reservoir through the liquid passage. A control valve controls the flow of the hydraulic liquid through the liquid passage, thereby controlling feed and discharge of the hydraulic liquid to and from the liquid piston-cylinder device in order to control the properties of the suspension. An accumulator is connected to the liquid passage between the liquid pump and the control valve and accumulates the hydraulic liquid under pressure. A return passage connects the reservoir to the liquid passage between the liquid pump and the control valve and is provided with an on-off valve which opens and closes the return passage. The on-off valve closes the return passage when the ignition switch is turned off.

Disclosed is a sheet feeding device for printers and the like, which comprises a detachable holder for thick cut sheets. In this device, thin ordinary cut sheets, supported in a pile by paper supporting means, are delivered one by one in a sheet feeding direction by feed rollers, which are in contact with the uppermost one of the sheets. In feeding relatively thick cut sheets, such as postal cards and other cards, the holder carrying the sheets thereon is detachably mounted on the supporting structure. The holder includes a supporting member for supporting the leading ends of the thick cut sheets, with respect to the sheet feeding direction. The supporting member has a slanting or curved guide surface. As the feed rollers rotate in contact with the uppermost one of the thick cut sheets, the sheets are delivered, sliding on the guide surface.

This invention provides a control method of a remote copy system for establishing a disaster recovery system for transmitting data in database by a copy function between storage devices possessed by the storage device so as to minimize a public line necessary for the data transmission. In a remote copy system for transmitting data in a main storage device to a remote storage device, the main storage device classifies a group of logical volumes for ensuring the data update order into a plurality of small groups and sets the utilization of a side file at which the data transmission is interrupted. When the quantity of data collected in the side file exceeds a threshold, data transmission is interrupted in the order from a small group having a lower utilization of the side file without stopping the data transmission of all logical volumes in the group.

Among two damping devices arranged in series between wheel side members and body side members, while in one damping device spring constant of a spring member is set low and damping coefficient of a damper member is set high, in the other damping device spring constant of a spring member is set high and damping coefficient of a damper member is set low. By this arrangement, difference in damping force between the area of low oscillation frequency and the area of high oscillation frequency can be made large, whereby running stability and comfortableness to ride in can be improved on a high level.

A suspension apparatus of a vehicle has a cylinder unit interposed between a sprang weight and an unsprung weight, which changes a ride height of the vehicle body by supplying or discharging an operating liquid through a supply/discharge control valve. The supply/discharge control valve is controlled on the basis of a predetermined condition so as to control a posture of the vehicle body. There are further provided a rebound detecting means for detecting a rebound of each of the wheels and a pressure detecting means for detecting a pressure in the cylinder unit. When the rebound is detected by the rebound detecting sensor to be above a given value, if the pressure detected by the pressure detecting means is continued at a magnitude above a given value for a given period of time, it is judged that the supply/discharge control valve is in trouble.

A suspension-steering control apparatus is provided with suspension-characteristic changing means for changing a suspension characteristic and a rear-wheel steering mechanism for steering rear wheels of a vehicle. The suspension characteristics is such that, for example, a magnitude of a damping force of a suspension or a rolling rigidity ratio of the rear portion of the vehicle body to the front portion thereof can be changed. The rear-wheel steering mechanism is controlled on the basis of a predetermined steering characteristic. The steering-characteristic is corrected in synchronization with alteration of the suspension characteristic.

摘要:
A technique is provided that easily detects biopolymers such as a DNA or a protein by utilizing semiconductor nanoparticles having different excitation wavelengths and fluorescence due to differences in particle size. By binding the semiconductor nanoparticles with avidin (or biotin), detection of biopolymers labeled with biotin (or avidin) is enabled.

Provided is an apparatus for detecting biopolymers (DNA) capable of total analysis including non-reacted samples without complicated operations such as washing. A DNA probe is fixed to one of electrodes and direct current voltage is placed between the electrodes, so that it becomes possible to separate complementary strand sample DNA and non-complementary strand sample DNA. By analyzing from a ratio in the whole reaction system, it is possible to obtain clearer results. Further, by using electrophoresis by gel together, it is possible to separate reacted samples and non-reacted samples to perform measurements therefor in the same reaction field.
