摘要:
There is disclosed a damping force controller for controlling a damping force characteristic of a damper disposed between an unsprung mass and a sprung mass of a vehicle. A control unit repeatedly compares an output signal of a load sensor with a predetermined range. After the sensor output signal has been kept deviated from the predetermined range over a predetermined period of time longer than a resonance period of the unsprung mass, a damping force of the damper is increased for enhanced stability of the vehicle.

A suspension control system for an automotive vehicle comprises a multi-stage variable damping force shock absorber which is variable of damping characteristics at a plurality of mutually different damping modes. The control system also comprises means for monitoring a vehicular driving parameter representing a suspension control parameter, a plurality of data maps set in a memory unit respectively containing a damping characteristics selection pattern for deriving damping characteristics, toward which the damping characteristics of the shock absorber is to be controlled, on the basis of the suspension control parameter. Means, responsive to the current damping characteristics of the shock absorber, are provided for selecting one of the data map, and means for performing suspension control with selected one of data map for deriving a suspension control signal by looking-up the selected one of data map in terms of the suspension control parameter for controlling damping characteristics of the shock absorber.

A shock absorber has a cylinder tube coaxially arranged with a strut tube for defining therebetween an annular reservoir chamber and an upper reservoir chamber which is separated from the annular reservoir chamber. A first fluid path is defined for permitting fluid flow from a lower fluid chamber in the cylinder tube to an upper fluid chamber and the annular reservoir chamber in response to bounding stroke of vibration. A second fluid path is also defined for permitting fluid flow from the lower fluid chamber and the annular reservoir chamber to the upper fluid chamber and the upper reservoir chamber, in response to rebounding stroke of vibration. A first flow restriction means is disposed in the first path for generating damping force in response to bounding stroke of vibration, which damping force is variable depending upon the magnitude of the bounding stroke in essentially linear variation characteristics. A second flow restriction means is also disposed in the second path for generating damping force in response to bounding stroke of vibration, which damping force is variable depending upon the magnitude of the bounding stroke in essentially linear variation characteristics.

A raindrop detection wiper is provided with a raindrop detector for detecting a raindrop, a wiper motor for actuating a wiper blade, an automatic stop mechanism for stopping the wiper blade at a predetermined position, a control mechanism comprising a current detector, a memory and the like for operating intermittently or stopping the wiper motor in accordance with a signal from the raindrop detector and memory data stored by the memory. According to this invention, it is possible to wipe the wiping surface automatically by detecting the raindrop and drive current of the wiper motor even in a very light rain.
摘要:
A central heat source system is used as the method of air-conditioning individual spaces, and warm water in the range of 15.degree. to 25.degree. C. is produced by a warm water generator having a heating device and a cooling device. The warm water is circulated among the warm water generator and a plurality of heat pumps connected thereto. In a certain room, the heat pump can be operated to perform cooling by using the warm water as cooling water, while in another room the heat pump can be operated to perform heating by using the warm water as heat source water. In addition, when the heated warm water used for cooling and the cooled warm water used for heating are returned to the warm water generator and are mixed therein, the thermal energy gained or lost by the respective warm water can be offset with each other, so that it is possible to reduce the amount of energy necessary for maintaining the warm water at 15.degree. to 25.degree. C., thereby making it possible to effect energy-saving in air-conditioning.

摘要:
A stacked piezoelectric actuator has a laminate structure including piezoelectric layers and cover parts such that when an external electrode is applied with drive voltage, the piezoelectric layers become distorted and the entire stacked piezoelectric actuator deforms, and at that time, the cover parts become displaced, wherein the distortion difference occurring between the piezoelectric layers and the cover parts reduces, thereby inhibiting the development of cracks. Moreover, the surface area of the active region of the piezoelectric layers is the same as the surface area of the active region of the cover parts, and therefore the loss of the displacement transfer, which is produced by the piezoelectric layers, at the cover parts is reliably reduced.

A portable information terminal apparatus generates a first signal, based on the user's operation, that causes a recording/reproducing apparatus to acquire program information. A second signal based on the user's operation, causes the recording/reproducing apparatus to display the acquired program information. A third signal based on the user's operation causes the recording/reproducing apparatus to preset the program for unattended recording. A fourth signal based on the user's operation causes the recording/reproducing apparatus to convert the recorded program to video data in a predetermined file format.
摘要:
The present invention relates to a portable information terminal apparatus for additionally displaying information about other programs broadcast in the same time slot as a user-selected program. A TV program recording preset program under control of an I/O control program receives input of a user-selected start time of a given TV program. In turn, the TV program recording preset program extracts from a program list memory not the user-selected time but the start and end times of the TV program relative to the selected time, and retrieves information about all TV programs to be broadcast between the extracted start and end times so as to create a table of TV programs available in the designated time slot. The table is output to a display unit for display under control of the I/O control program.
