Title: Liquid crystal electrooptic device
Inventor: KOBAYASHI IPPEI
IPC: G02F1/137
Filed: 1987-02-13
Abstract: PURPOSE:To eliminate the need for narrowing the inter-substrate spacing of a cell and to facilitate mass production by untwisting the spirals of liquid crystal molecules by the electric field to be impressed to the cell and controlling the angle at which the liquid crystal molecules incline by the positive or negative electric field and the impression time thereof. CONSTITUTION:The ferroelectric liquid crystal is put into the cell of an ordinary liquid crystal electrooptic device. The spacing between the substrates of the cell is set slightly wider so that the liquid crystal 5 can maintain the spiral state. The liquid crystal molecules 8 assume the spiral state having the spiral axis in the direction parallel with the substrates 2 while no electric field is held impressed to the cell from the outside. The liquid crystal molecules 8 assume the state B or C shown in the figure when a voltage is impressed between upper and lower electrodes 3 to generate the electric field in the cell in this state. The liquid crystal molecules 8 change the direction like C or B in the figure if the electric field in the cell is inverted. The change in the transmitted light arising from the difference in the angle at which the liquid crystal molecules incline is detected by polarizing means 1, 7 provided on the outside of the cell, by which the change in the transmission is embodied to make display. Since bistability is not needed, a larger industrial margin is allowed at the time of the production.

Filed: 1990-02-13
Abstract: PURPOSE:To hold a specific contrast and color balance and to obtain stable display quality by forming a transparent conductive film between a glass substrate and an orienting film. CONSTITUTION:Transparent conductive films 2a and 2b and orienting films 3a and 3b are formed on the inside surfaces of glass substrates 1a and 1b, which are sealed with a seal material 6 while liquid crystal 4 and spacers 5 are sandwiched.

Abstract: PURPOSE:To improve the operability in data input by displaying a shifting con- dition to make the movement of operator's eyes easy at setting the shift stage and at operating a input key. CONSTITUTION:When the shift stage corresponding to the item to which the operator wants to input, for example, is the 3rd stage, the input key K3 having the item corresponding to the 3rd stage is depressed. Then, the C2 input of a coincidence circuit 63 is set to logic ''1'' and the D2 input is set to logic ''0'', respectively. In this case, the J input of FF33 becomes ''1''. Then, the FF33 is set by the fall of a clock signal 17 at that time and only a lamp 3 is lighted continuously on a input keyboard 3. Simultaneously, and AND gate G7 is energized to make the clock signal 17 pass and the signal is fed to the 2nd frequency dividing circuit 91. A frequency dividing ratio N2 of the 2nd frequency dividing circuit 91 is set larger than a frequency dividing ratio N' of a 1st frequency dividing circuit 41. By means of this, confirmation of the shifted items corresponding to the depressed input key can be performed by prolonged lighting duration of lamps S1-S4.

Title: Synchronization pattern detection system
Inventor: IKEGAMI HIROSHI
IPC: H04L7/08
Filed: 1991-02-27
Abstract: PURPOSE:To suppress remarkable deterioration in a detection probability of a frame synchronizing signal included in a serial data in a digital communication line with a high error rate. CONSTITUTION:A coincidence circuit 4a discriminates the coincidence between a frame synchronizing signal included in a serial data 2 and a predetermined synchronization pattern 5 for each bit and the result of discrimination controls analog switches 6-1-6-n for each bit. When an output of an analog adder 8 exceeds a level of a comparison signal 11 fed to an analog comparator 12, a comparison output 13 goes to a high level and the end of synchronization is discriminated. The synchronization bit number in the synchronization pattern comprising plural bits is set in the unit of bit. Thus, the discrimination criterion is realized in a range not causing an error to suppress the reduction in the frame synchronization detection probability considerably.
