摘要:
A stabilizer control apparatus includes a first torsion bar, a second torsion bar, and a connecting and disconnecting means including a rotation member rotating as a unit with the first torsion bar, and a housing accommodating therein the rotation member so as to be rotatable and forming two pressure chambers, the two pressure chambers being filled with a fluid. The connecting and disconnecting means generates a connecting state in which a movement of the fluid to the two pressure chambers is blocked so that a relative rotation between the first torsion bar and the second torsion bar is prohibited and a disconnecting state in which a movement of the fluid to the two pressure chambers is allowed so that the relative rotation between the first torsion bar and the second torsion bar is allowed.

摘要:
Distortions of motor voltage and current and a torque ripple of the motor are generated by dead band compensation for preventing an arm short circuit of an inverter, and a feeling of physical disorder is given in a handle operation. Therefore, the distortions of the motor voltage and current and the torque ripple of the motor are improved by using the dead band compensation for estimating the voltage distortion on the basis of a model current generated from a current command value such that no feeling of physical disorder is given in the handle operation of an electric power steering apparatus.

A wireless operating system, which is used with a mobile telephone, for wirelessly operating an operated target, includes: an adapter including transmitting means for allowing operation information required for an operation of the operated target to be transmitted by short distance radio; a short distance wireless unit having receiving means for receiving the operation information and operating means for operating the operated target in accordance with the received operation information; and an operated target control unit. The adapter further includes: communication means capable of performing direct communication with the mobile telephone by being carried with the mobile telephone; and operation information generating means for generating operation information in accordance with portable communication terminal information acquired from the mobile telephone. Under the circumstances where a user carries the mobile telephone, it is possible to provide a wireless operating system in which various operated targets and the mobile telephone are wirelessly operated.
摘要:
To provide an optical assembly capable of enhancing black level display while preventing deterioration of a WV film, and a projector assembled therewith, optical compensation elements are disposed before and after liquid crystal light valves, so that an unintended phase difference generated on the incident and emission sides of the liquid crystal light valves for individual colors is eliminated by adjusting the rotational positions of the optical compensation elements, thus enabling an enhancement in the contrast of a color image displayed on a transmission screen member. In case of B light including ultraviolet light in part, the optical compensation element is disposed at the subsequent stage of the liquid crystal light valve, so that as compared with when the optical compensation element is disposed at the preceding stage of the liquid crystal light valve, the optical compensation element can be reduced or prevented from deteriorating with age, thus enabling the contrast of image display to be maintained over a long period of time.

It is possible to certainly prevent a vehicle from being stolen at low cost. A user of an automobile 31 registers an on or off state of a security mode with a center apparatus 33 in advance. When abnormality is detected by a sensor 41, the abnormality is notified to a center communication device 52 from an on-vehicle communication device 43 through a communication network 34. When the security mode is on, a center control device 51 notifies the abnormality to a portable telephone 32 of the user of the automobile 31 through the communication network 34.
摘要:
An ink jet recording apparatus is provided with a black head and a plurality of color heads. The black head has a predetermined number of first orifices aligned at predetermined intervals (e.g. 0.0169 mm) in a sub scanning direction (direction in which a print medium travels). The plurality of color heads eject different colored ink drops. Each color head has the predetermined number of second orifices aligned in the sub scanning direction perpendicular to the main scanning direction. The second orifices of adjacent color heads are aligned in a main scanning direction perpendicular to the sub scanning direction.
摘要:
A system for detecting an ink consumption in an ink jet recording device comprises a non-volatile memory for storing an accumulated amount of ink consumption, update section for incrementing the stored amount by a new amount of ink consumption, a comparator for comparing the accumulated amount against a variable reference amount, and a display section for displaying the accumulated amount of ink consumption or a residual amount of ink in the ink jet recording device. The recorded amount includes total ink consumption by nozzle cleaning, nozzle suction and ink discharge.
