Abstract: PROBLEM TO BE SOLVED: To obtain a liquid crystal display device with a driver circuit in one body having a small size, a large aperture ratio and high reliability by forming signal lines and pixel electrodes as separated layers by using a polyimide as an interlayer insulating film. SOLUTION: A pixel driving transistor 209, pixel electrode 210, scanning lines included in a first wiring layer 211 with the pixel driving transistor 209 and a gate electrode of a driver circuit 203, and signal lines included in a second wiring layer 212 are formed in a display region 202. The first wiring layer 211 and the second wiring layer 212 are insulated from each other by a first interlayer insulating film 213, and the second wiring layer 212 and the pixel electrode 210 are insulated by a second interlayer insulating film 214. The second interlayer insulating film 214 is removed in the area on the driver circuit 203 and the area under the seal 206. Therefore, the aperture rate can be increased. Since a polyimide can be formed by a spin coating method, the surface of the element substrate can be formed flat, which prevents disturbance in the alignment of a liquid crystal.  Thus, a display of high quality can be obtd.

IPC: G02B6/12
Filed: 1990-04-27
Abstract: PURPOSE:To allow an edge to a high electric field part and to increase superposition between the formed part and input light by arranging 2nd clad part on a prescribed position adjacent to 1st clad part and having electric resistance different from that of the 1st clad part. CONSTITUTION:The optical switch is obtained by adjacently forming the 1st clad part 51 having low electric resistance and the 2nd clad part 52 having electric resistance higher than that of the 1st clad part 51 on the surface of a base 50 forming an electrode 50a on its bottom. An optical wave guide layer 53 is formed on the whole surface of both the clad parts 51, 52 and clad layers 54a, 54b, clad layers 55a, 55b and electrodes 56a, 56b are successively formed on the layer 53 with a prescribed interval. When voltage is impressed to the electrode 56a an electric field E is concentrated into the edge part 51a of the clad layer 51 and a high electric field part is generated. Consequently, superposition between the high electric field part and input light is increased and operation voltage necessary for switching can be reduced.

Abstract: PURPOSE:To prevent noises from increasing by stopping speaker output for sound elimination for a constant time if vehicle body vibration from a road surface exceeds a threshold value when a speaker is controlled by an adaptive controller by using an engine vibration detecting means so that the input of a microphone becomes minimum. CONSTITUTION:This device is equipped with the adaptive controller 5 which identifies the reverse transfer function of a transfer function G from the vibration system of a vehicle body to the ear, the speaker 6 which outputs the output signal of the controller 5 into the vehicle room, the microphone 4 which detects all in-room vehicle noises, and a means 10 which detects the vehicle body vibration from the rod surface. Then the controller 5 controls the speaker 6 so that the input of the microphone 4 becomes minimum and when the vehicle body vibration obtained by the vehicle body vibration from the road surface by another means 10 exceeds the threshold value, the output from the speaker 6 is inhibited for the constant time. Consequently, the in-room vehicle noises are prevented from becoming worse.

IPC: H04N1/00
Filed: 1995-04-17
Abstract: PURPOSE: To reduce an entire communication time by eliminating negotiation of size revision in the case of sending plural originals in mixture of different sizes. CONSTITUTION: Magnification or the like for image processing of a head page is decided by a recording paper size information detection section 46 of an opposite equipment. The magnification or the like is decided for second and succeeding pages in matching with the size after processing of a head page in place of the recording paper size of the opposite equipment and the longitudinal and lateral directions. An image processing section 44 conducts image processing such a magnification, reduction or rotation based on the decided magnification or the like and sends the resulting image.

Title: Information reproducing device and reproducing method
Inventor: YAMAGUCHI SHIGEO
IPC: G11B7/00
Filed: 1997-05-02
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of an abnormal amplitude reference value caused by a defect or the like without damaging effect of adaptation by setting the initial value of the amplitude reference value to an amplitude reference value so as to update for each clock based on the operation result of a reproducing signal and a Viterbi decoding method when an amplitude reference in which a prescribed discrimination reference is not satisfied is generated. SOLUTION: An amplitude reference value adaptation block (RAA) 101 calculates a new amplitude reference value based on a state data vale sm[k+n] supplied at each point of time and a reproduced signal value delayed by (n) clocks and supplies it to a Viterbi decoder 130. An amplitude reference value initializing block (RAinit) 102 sets the initial value of the amplitude reference value to the RAA 101 when the newly calculated amplitude reference value does not satisfy the prescribed discrimination reference. Thereby, the initial value is not a value obtained by adaptation, but as it is not an abnormal value, the reduction of decoding accuracy can be prevented without failure of a Viterbi decoding.
