摘要:
A display apparatus is constituted by a display device including a plurality of scanning lines, a plurality of data lines intersecting the scanning lines, and a pixel formed at each intersection of the scanning lines and data lines and showing plural display states depending on signals applied to an associated scanning line and an associated data line. The display device is driven by applying a selection signal to the scanning lines and applying to the data lines data signals for causing prescribed display states at the pixels in association with the selection signal. Further, at least one scanning line in a nonselected state is supplied with a dummy signal for temporarily changing display states of pixels on the at least one scanning line, whereby flickering on the display device is suppressed. The display apparatus is also applicable to gradational display.

Disclosed is an ATM exchange for granting permission to a camp-on request in a short time. A temporarily saved band value management table for managing temporarily saved band value is provided, as is a band management table for managing empty band value in the storage device of an ATM exchange comprising a storage device, a control device, and the like. The control device selects a corresponding empty band value for a temporarily saved band value when a first camp-on request is received from a terminal, and sets the empty band value to "0." In addition, the control device adds to the temporarily saved band value a band value released by a break in communication when a camp-on request is registered, and grants permission for communication to the terminal that has issued this camp-on request when the temporarily saved band value is higher than the band value required by a registered camp-on request. The control device determines whether or not a connection request can be accepted on the basis of the empty band value stored in the band management table.

Code conversion tables for some major language spheres are stored in a ROM 13 in a printer. Pattern information of all kinds of characters, discriminately represented by their internal codes, are stored in a character generator 15. For code conversion tables for other language spheres than major language spheres, the definition information of each code conversion table is registered in an EEPROM 17 in the printer, from a host device. The definition information of a code conversion table may be prepared by defining the internal codes corresponding to all of the external codes. The definition information may also be prepared in such a way that a code conversion table is selected from among the code conversion tables stored in the ROM 13 and used as a base code conversion table, and only information of the code conversion table which is different from that of the base code conversion table, is defined. Before the printing operation is performed, a CPU 19 prepares a code conversion table in a RAM 7 on the basis of related definition information in the EEPROM 17. During the printing operation, the CPU 19 refers to the code conversion table in the RAM 7.

A zoom lens is disclosed, comprising a front lens group having a first, a second and a third lens units, totaling at least three lens units, and whose overall refractive power for the wide angle end is positive and a rear lens group having a lens unit of positive refractive power and another lens unit of negative refractive power, wherein when zooming from the wide angle to the telephoto end, the first, the second and the third lens units all axially move in such relation that the overall refractive power of the front lens group is weaker in the telephoto end than in the wide angle end, and the lens units in the rear lens group all axially move in such relation that their separation narrows.

An air conditioning control system ensuring the desired full utility so that the operation of a plurality of air conditioners installed in a building can be controlled and monitored at a plurality of spots in the building. The air conditioning control system includes a building's central monitor board controlling and monitoring the operation of the individual air conditioners, and a centralized control unit relaying air conditioner control information outputted from the central monitor board and information indicating the operation status of the individual air conditioners, each of the central monitor board and the centralized control unit including an input part inputting the control information to the individual air conditioners and a display part displaying the operation status information regarding the individual air conditioners. The centralized control unit further includes a decision part deciding to identify newest control information inputted from the input part of each of the central monitor board and the centralized control unit and a transmitter part transmitting this newest control information to the individual air conditioners.
摘要:
An air bag apparatus in which the appearance of the interface between the portion covering the air bag and portions surrounding it can be improved, the number of components can be reduced, and the assembly process can be shortened. A cover unit covers an air bag, which inflates on a predetermined occasion, consists of a cover which-opens with the inflation of the air bag, and a body for holding the cover. The cover unit is an integrally molded product in which a skin is formed on a substrate, and includes, at the location connecting the periphery of the cover with the body, a breakaway portion along which the cover is separable from the body when the air bag inflates, and a hinge portion for maintaining the connection of the body and the cover. In the breakaway portion, the substrate has a fragile portion, and the skin is separated into two parts at the position of the fragile portion. In the hinge portion, the substrate and skin are continuously formed and extend from the body to the cover.

A beam spot controlling method for controlling the beam-converging position by a light beam from an objective lens on a recording track of a recording medium comprising the steps of (a) rotating a tapered prism having an inclination-imparting portion capable of imparting an inclination to a light beam which enters the tapered prism for changing the inclination of the light beam incident on said objective lens for controlling the beam-converging position by the light beam; (b) causing a light beam to enter the tapered prisms; and (c) causing the light beam exiting from the tapered prism to enter the objective lens, and directing the exiting light beam onto the recording track of said recording medium, and an apparatus for performing the above beam spot controlling method.
