Title: Liquid crystal display element and production thereof
Inventor: TATSUTA SUMITAKA
IPC: G02F1/13
Filed: 1989-06-13
Abstract: PURPOSE:To obtain the liquid crystal display element having good orientability and good memory characteristic by adopting such a combination of an oriented film and a ferroelectric liquid crystal with which the contact angle of the liquid drop of the ferroelectric liquid crystal is >=53 deg. at the upper limit temp. when the above-mentioned liquid drop is dropped onto the oriented film. CONSTITUTION:The oriented film subjected to an orientation treatment and the ferroelectric liquid crystal are formed of such a combination of the oriented film and the ferroelectric liquid crystal with which the contact angle of the liquid drop when the liquid drop of the ferroelectric liquid crystal is dropped onto the oriented film is >=55 deg. when the temp. is increased from the inclined smectic phase forming temp. region of the ferroelectric liquid crystal to the upper limit temp. thereof. The reason thereof lies in that the effect of improving the memory characteristic is by the treatment to impress electric fields only with the combination of the liquid crystal and the oriented film with which the contact angle at the upper limit temp. of the Sm* phase at the time of the temp. rise is >=53 deg.. In addition, this effect of improving the memory characteristic exhibits the tendency to increase with an increase of the contact angle in excess of 53 deg.. The ferroelectric liquid crystal display element having the good orientability and memory characteristic is obtd. in this way.

IPC: H02P6/12
Filed: 1995-05-24
Abstract: PURPOSE: To judge the abnormality of a position detection system and discontinue the operation of a brushless motor by a method wherein the time interval of the detection of the position of a rotor is calculated and, if the calculated time interval is out of a required time interval range, the operation of the brushless motor is discontinued. CONSTITUTION: Every time when the position of the rotor 4a of a brushless motor 4 is detected in accordance with the terminal voltages R, S and T of the windings of the brushless motor 4, a control circuit 10 calculates a position detection time interval by using the present position detection time and the previous position detection time. It is judged whether the calculated time interval is within a required time interval range or not. If the calculated time interval is out of the required time interval range, it is judged that there is the abnormality in a position detection system and, further, the operation of the brushless motor 4 is discontinued.  For instance, if a position detection unit 5 is failed, connection lines between the terminal voltages R, S and T of the brushless motor 4 are open or there is an erroneous connection in the wirings, the calculated time interval will be out of the required range. With this constitution, for instance, damages of an inverter circuit 3 and the brushless motor 4 can be avoided.

Abstract: PURPOSE: To classify laver sheets repidly according to the quality, by passing the dried laver sheets through a gap between the upper array of light sources and the lower array of light receptors each disposed at regular intervals, and detecting the number of the light receptors to which the light from the light source is transmitted.

The arrays are disposed in parallel, and the light sources, etc. are arranged at regular intervals in the array. The light beams 6 and 6' emitted from the adjacent light sources 4 intercross each other at the path of the laver sheet. When the laver sheet passing through the gap 3 is free of light-transmitting hole, the light receptor circuit is opened, and the detector circuit 11, the operating circuit 12 and the signal circuit 13 are inactivated to accumulate the laver sheet 2 in a box for high-quality laver sheet. When the laver sheet has a hole larger than the interval (t), the light receptors 5 detect the light beams 6 and 6', activate the circuits 9, 11, 12 and 13, count the number of the light beams 6, 6', and determine the grade of the laver sheet 2.

Abstract: PURPOSE:To increase the number of combinations between signals I and Q to 55 from conventional 27, by providing a means to eliminate in steps the 3rd and 2nd higher harmonic waves of the signals I and Q which have a single frequency respectively. CONSTITUTION:An input video signal (x) is led to a superposing circuit 1 which superposes the signals I and Q and at the same time applied to a synchronism detector 3 in a generating circuit 2 for signals I and Q. The circuit 2 forms 11 types of combinations of single frequency signals (produced from a generator 6 for an IQ signal) based on the detected synchronizing signal. Then the output of combination is supplied to a low pass filter 13 which eliminates the 3rd higher harmonic wave. The output of the filter 13 is fed to band pass filters 16-18 for extraction of the 2nd higher harmonic wave within a higher harmonic detecting/eliminating circuit 14 and then applied to a higher harmonic eliminating circuit 19 after the phase control (21-23) and the level control (25-27). In such way, an IQ signal (i) is obtained. The 2nd higher harmonic wave is excluded from the signal (i). The signal (i) is superposed on the signal (x) by a superposing device 11 to obtain a program transmitting signal (y).

Abstract: PURPOSE: To measure the signal level of the reproduction output, by supplying the change of magnetization of the servo track to the counting means and then converting the count value into the output level value through a converting circuit for display.  
     CONSTITUTION: The servo track signal recorded to the cartridge tape medium is converted into the electric signal through the reproudction head 201 and then supplied to the counter circuit 205 via the full-wave rectifying circuit 203 and the slicing circuit 204. Then the number of the output signals of the circuit 204 is counted, and the count value is converted into the output level value through the converting circuit 206 to be displayed on the output display circuit 207. Thus the output level value is measured while the servo track is normal, and then record state can be presumed based on the output level value. In this way, the record state of the servo track and the reproduction output level can be known just by adding a simple circuit.
