Title: Television receiver and on-screen signal generator
Inventor: SHIODA KAZUTAKA
IPC: H04N5/445
Filed: 1993-10-28
Abstract: PURPOSE:To eliminate distortion of an on-screen picture when a video image whose aspect ratio is 4:3 is displayed on the entire display screen whose aspect ratio is 16:9 while the display size of the video image in the horizontal direction is magnified closer to left and right edges relatively with respect to a middle part in the horizontal direction. CONSTITUTION:An on-screen picture outputted from a character generator 1 is written in a VRAM 2 and one line of the picture is inputted to a shift register 4. The shift register 4 decomposes the picture in the unit of picture elements based on a reference clock received from a reference signal generator 6 to provide an output of an on-screen signal. A parabolic waveform generating circuit 61 generates a parabolic waveform signal, and a VCO 62 outputs a reference clock whose frequency is higher at both edges in the horizontal direction and whose frequency is lower in the middle. Thus, the displayed size of the on-screen picture is reduced relatively toward the left and right edges with respect to the middle part in the horizontal direction and then distortion is cancelled.

Abstract: PURPOSE: To secure the light quantity of illumination light and to make illumination waveforms uniform simultaneously by sealing the light emitting surface of a light emitting element by a transparent resin material provided with a different light diffusion property corresponding to the position and light quantity of light emitted by the light emitting element. CONSTITUTION: The light emitting surfaces of a red LED 23 and a blue LED 21 whose emitted light quantity per piece is large are sealed by translucent resin 33 provided with a diffusion property. Thus, the illumination waveforms are approximately uniformized.

Title: Switching element
Inventor: MATSUMURA KOJI
IPC: H01L29/778
Filed: 1988-11-18
Abstract: PURPOSE:To improve a switching speed by a method wherein one of two channels is in an ON state and the other is in an OFF state and a bias applied to one gate is changed to switch over the ON and OFF states of both the channels. CONSTITUTION:Normally, a current along an X-Y direction between a source electrode 1 and a drain electrode 2 is in an OFF state and a current along a U-V direction between a source electrode 4 and a drain electrode 5 is in an ON state. Then, if a bias applied to a front gate 7 is changed, electrons stored in a channel I 19 directly under the front gate 7 are transferred to a channel II 20 and, finally, a potential state is obtained. In other words, electrons in the channel I 19 are removed and a two-dimensional electron gas is formed in the channel II 20. With this process, the current along the X-Y direction is turned ON and the current along the U-V direction is turned OFF. That is, electrons are transferred between the channel I and the channel II without charge and discharge of electrons, so that a very high switching speed can be achieved.

IPC: G11B20/10
Filed: 1986-12-10
Abstract: PURPOSE:To improve reliability of an information signal in a recording/reproducing mode by driving a laser power source so as to increase the number of sections where the reflected light quantity is reduced in a reproducing mode compared with those sections where the reflected light quantity is increased, and recording signals. CONSTITUTION:The output of a differentiation signal 13 is supplied to a code inverting circuit 51 and the output of the circuit 51 is inverts the code of the output of the circuit 13. Therefore, the total light emitting period of a semiconductor laser 15 is longer than the total non-light emitting period when the laser 15 is driven by the output of a code inverting circuit 14. Then the number of sections where the reflection factor is reduced by recording is increased compared with those sections where the reflection factor is increased. As a result, the error occurring probability is reduced even though the reflected light quantity is reduced in a reproducing mode due to the foreign matters 36 mixed into a protecting substrate 31 of a recording medium or the dust/stains 37 and scratches, etc., on the surface of the substrate 31 owing to a shorter period during which errors occur by the matters 36, etc., with large reflected light quantity.
