Title: Porous anisotropic conductive elastomer
Inventor: KURAMOCHI HIROSHI
IPC: C08J9/26
Filed: 1993-02-18
Abstract: PURPOSE:To obtain the subject elastomer which is very flexible, is excellent in cuttability-an important property in its processing, and does not cause bending of a conductor at a cut point. CONSTITUTION:An anisotropic conductive elastomer is produced by using, in place of a insulating elastomer in a conventional anisotropic conductive elastomer, an insulating elastomer filled with aggregate particles usually used for making a material porous, and is cut to a required size. Since the insulating elastomer contg. the aggregate particles has an increased hardness and is excellent in cuttability, the anisotropic conductive elastomer of this invention, unlike a conventional one, does not cause bending of a conductor at the cut point even when a thin metal wire is used as the conductor. After the cutting, the anisotropic conductive elastomer is immersed in a solvent to dissolve the particles to remove them from the insulating elstomer, making the insulating elastomer porous and very flexible.

Filed: 1988-03-25
Abstract: PURPOSE:To stably attain the transmission of picture data to any opponent and to improve communication efficiency by executing communication control in each communication opponent, changing a communication route in advance according to the condition of a line to the opponent and transmitting the data. CONSTITUTION:The picture data to be read in a reading part 1 are once accumulated in a picture memory 8. After modulation is executed in a MODEM part 3 on the basis of these data, the data are sent on the line through a network control part 4. In such a case, when there is no error at the time of transmission processing, normal transmission control processing is executed. On the other hand, when the error is generated, a communication result in the past is referred for the generated error and an error generating rate is computed in each communication opponent. Then, this result is written to the communication control information area of a storing part 7, here, a main control part 6 selects the line of the low error rate on the basis of the control information of the storing part 7 and transmits the picture data. Thus, since the generating rate of the line error can be grasped in each opponent and the other line can be automatically set on the basis of these data, the communication efficiency can be wholly improved.

Title: Driving method for liquid crystal light valve
Inventor: OTA SUNAO
IPC: G09G3/18
Filed: 1987-03-24
Abstract: PURPOSE:To obtain a high contrast ratio and to reduce deterioration due to a DC component even when a ferroelectric liquid crystal which is inferior in memory performance is used by applying a voltage pulse which determines the light transmission state of a liquid crystal light valve at a prescribed period and applying a voltage pulse for DC correction which sets the mean value of a voltage applied to the ferroelectric liquid crystal in the same period to zero, and then controlling charges accumulated in the liquid crystal by driving circuits provided corresponding to plural respective dots. CONSTITUTION:When a liquid crystal light valve is turned on, a voltage pulse 2 of level -V which corrects a DC component is applied in a period where a signal 102 for determining the timing of the application of a voltage pulse to a liquid crystal element is at high level, e.g. in the former front t11 of t1, and a voltage pulse 1 of level +V which places the liquid crystal light valve in a light transmission state is applied in the latter half t12; and a high- impedance state is entered in the remaining t13. The charges accumulated in the t12 decrease in the period t13 by the self-discharge in the liquid crystal and discharge through a driving circuit. Further, the resistance of the liquid crystal and driving circuit is sufficiently high so a voltage VLC across the liquid crystal is high enough to make liquid crystal molecules respond even at the end of the t13, and the liquid crystal molecules are held in an on-state with the voltage VLC. Consequently, the high contrast ratio is obtained.

Filed: 1986-03-28
Abstract: PURPOSE:To attain quick correction even when a bit error takes place in a digital value stored in a register by adding a bit error correction circuit correcting the bit error automatically to a register storing tentatively the digital value. CONSTITUTION:An error correction code generated based on a data written at first by an error correction code generating section 32 is stored in a storage section 33. Then a digital data stored in a register l is read at any time by a register content read section 31. Then a comparison sectoin 34 compares the data with an error correction data stored in the section 33, then whether or not a bit error takes place is discriminated. If a bit error takes place, and when the bit error rate is small, the bit error is corrected automatically based on the error correction code. When the bit error rate is large and it is not corrected automatically, an alarm is raised to a CPU to urge the processing such as re-loading.
