An EL element having a color filter formed on an upper electrode thereof enables a decrease in the pixel loss or line defects. In the EL element, a lower transparent electrode, first insulating layer, luminescent layer and upper transparent electrode are laminated on a glass substrate. Further, a color filter is formed on the upper transparent electrode. As the color filter there is used a posi-resist having an average molecular weight in a range of from 100 to 50000 or a nega-resist having a polymerization reaction percentage in a range of from 5% to 70%.

An electro-luminescent display apparatus which is capable of displaying two kinds of images is disclosed. The apparatus has a front and a rear electro-luminescent unit therein, and the green light emitted from the front unit directly displays the real image which looks close to a viewer while the orange light emitted from the rear unit is reflected by a reflector disposed at the back of the apparatus and displays a virtual image which looks far from the viewer. In order to reflect the light emitted backward from the front unit and the light emitted forward from the rear unit, reflecting electrodes are provided on the rear surface of the front unit or a reflecting film is disposed in the space between the front and the rear units.

An optical scanning device includes an image reading station and a printing station wherein image reading and recording operations are accomplished using an optical system common to both the image reading station and the laser printing station. Recording and reading light beams having different wavelengths are separately emitted from two semiconductor lasers and are combined by a first dichroic mirror. The combined laser beams are deflected by a polygon mirror to scan a predetermined range and then focused by a focusing lens. The laser beams emerging from the focusing lens are applied to a second dichroic mirror where the recording and reading light beams are separated. The recording light beams are directed toward a photosensitive drum to irradiate thereonto. The reading light beam is directed toward an original document placed face down on a glass plate. The scattering light from the original document is detected by photo-detectors to produce an image signal indicative of the image on the original document. To print the original document, the recording light beam is modulated according to the image signal output from the photo-detectors.

摘要:
A condition of not permitting an increased temperature value of a diode to exceed the junction temperature is satisfied by a simple structure at a low cost. A plurality of countercurrent prevention diodes between terminal boards to which electrodes of solar cell modules are connected are connected in parallel. When an output current from the solar cell module flows in a circuit of the plurality of diodes connected in parallel, a current flowing in each diode is reduced by a factor of the number of diodes connected in parallel, for instance, when the three diodes are connected in parallel, the current becomes one third. When the value of the flowing current is reduced, a heating value is also reduced. A heat radiating piece is provided on the terminal board.

There is provided a vehicle drive control system performing the stability control of a vehicle by highly accurately and easily sensing accelerations generated in each tire and sensing a tire ground contact pattern, a sensor unit thereof and a tire. Using a sensor unit 100 mounted in each tire 2 of a vehicle 1, accelerations generated in X, Y and Z directions are sensed and at the same time, a low frequency noise component and high frequency noise component added to the Z axis direction acceleration signal are extracted. Digital values being the sensing result are transmitted as digital information to a monitor device 200 by radio wave. The monitor device 200 compares many pieces of tire ground contact pattern information preliminarily stored with the digital information to thereby specify a tire ground contact pattern and output the information to a stability control unit 700. The stability control unit 700 performs, based on the acceleration values and the information on tire ground contact pattern obtained, the correction control of driving of a sub-throttle actuator 412 or a brake drive actuator 640.

An acceleration sensor-attached tire is provided which can detect acceleration in one arbitrary direction, in two or more directions where vectors are linearly independent of each other, or in two or more directions where vectors of the detected acceleration cross each other generated in a tire in a practical velocity range. A sensor unit 100 is embedded inside a tire, and the acceleration in three directions crossing each other and generated in the tire 300 is detected by an acceleration sensor provided in this sensor unit, and the detected acceleration is transmitted.
