Title: Vertical synchronism detector circuit
Inventor: KITAZAWA KEIO
IPC: H04N5/10
Filed: 1978-10-23
Abstract: PURPOSE: To obtain a vertical synchronism detector circuit which is suited for formation into the integrated circuit and can obtain the pulse of the steady phase.  
     CONSTITUTION: The composite synchronous pulse isolated by synchronous isolator circuit 22 is applied to up-down counter 23. And counter 23 is switched to the up-counting when the synchronous pulse exists and to the down-counting when no synchronous pulse exists. Up-counting clock pulse generator circuit 31 is provided along with down-counting clock pulse generator circuit 32, and the both circuits generate the clock pulses of different frequencies to each other. Then the output of counter 23 is supplied to comparator 35 to be compared with the data determined previously. Comparator 35 delivers the rise pulse when the output given from counter 23 becomes larger than the set data. Thus counter 36 is driven to lead out the vertical synchronous pulse to output terminal 37.

Filed: 1987-05-27
Abstract: PURPOSE:To maintain always the good contrast of an outside world image and symbol image superposed on a combiner independently of the brightness of the outside world by providing an outside world light shutter which changes the transmittance of the outside world light in accordance with a luminance detection signal. CONSTITUTION:This device has a display device 10 which emits the symbol light A corresponding to the symbol image 70 superposed on the outside world image and the combiner which is disposed in front of an observer's position and superposes the outside world light B corresponding to the outside world image 50 transmitted from the rear face on the symbol light A. The device has a luminance detector 30 which detects the luminance around the image 50 and outputs the same as the luminance detection signal and the outside world light shutter 40 which changes the transmittance of the light B in accordance with the luminance detection signal. The transmittance of the light B transmitted through the combiner 20, therefore, changes according to the luminance around the image 50. The contrast of the outside world image 50 and symbol image 70 superposed by the combiner 20 is thereby maintained always in the desired state independently of the brightness of the outside world.

When the gate scanning voltage Vg goes to a low level, the transferred data signal is held in a voltage holding capacity 105, The extent of voltage shift is reduced by increasing the value of the voltage holding capacity 105. An amplifier input voltage Va is held till the gate scanning voltage Vg goes to the high level again in the next field period and a transistor (Qn) 103 is selected. The analog amplifier circuit 104 outputs an analog gradation voltage corresponding to the amplifier input voltage Va held till the change of the amplifier input voltage.

IPC: C08B3/00
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To efficiently obtain a cellulose derivative which is soluble in water and excellent in water absorption properties, etc., by effecting a reaction for introducing a substituent to cellulose in a mixed solvent comprising tetraethylammonium chloride and a sulfoxide compound. SOLUTION: Cellulose (for example, wood pulp) is dissolved in a mixed solvent comprising tetraethylammonium chloride and a sulfoxide compound (for example, dimethyl sulfoxide). Further, another organic solvent such as triethylamine or acetonitrile may be additionally used. Subsequently, in the resultant homogeneous reaction system, a reaction for introducing a substituent to cellulose is carried out, to obtain a cellulose derivative. For instance, in order to introduce a sulfonyl group to cellulose, a sulfur trioxide complex is added to the above-mentioned homogeneous reaction system and, the resultant mixture is allowed to react at a temp. of about 0 to 50 deg.C for about 5min to 20hr, to thereby obtain a cellulose sulfate.  By using this method, a cellulose derivative which has a high degree of substitution can be produced without causing a decrease of the molecular weight of the starting cellulose or a lowering of quality such as discoloration.
