IPC: G03H1/08
Filed: 1990-03-15
Abstract: PURPOSE:To allow the control of the refractive index of each picture element by the voltages which switching elements impress to a liquid crystal layer by forming a 1st oriented film and a 2nd oriented film in such a manner that the respective orientation directions are approximately paralleled with each other. CONSTITUTION:The voltages are impressed to the liquid crystal layer 208 by plural pieces of the switching elements 202 formed on a substrate 201, by which the refractive index of the liquid crystal molecules of each picture element is controlled and, therefore, the number of the picture elements constituting the liquid crystal 208 is effectively utilized. Since this element is of a reflection type, the phases of the incident light are modulated by double paths and, therefore, the modulation of the phases is larger than a transmission type and the phase modulation with the good efficiency of light utilization is executed. The phases of the incident light are modulated by controlling the refractive index of the liquid crystals of each picture element in such a manner and, therefore, the phase modulation with the good utilization efficiency of the picture elements is executed.

IPC: G01N17/00
Filed: 1978-05-31
Abstract: PURPOSE: To non-destructively inspect the corrosion resistance of iron-nickel-chromium base alloys by measuring the change in eddy current value.  
     CONSTITUTION: Corrosion resistant alloys of Ni-Fe-Cr base, Ni-Cr-Fe base, FeNi-Cr Base, etc. are sensitized by heating hysteresis at 500 to 700°C resulting in decreased corrosion resistance. Further the sensitization is restored by long-term heating hysteresis of 500 to 800°C, resulting in the restored corrosion resistance. In correspondence to the abovementioned phenomena, the eddy current measuring value of the sample becomes small at the sensitizing phenomenon and becomes larger at the sensitization restoration time. Corrosion resistance test is performed by using these. Namely, a solution heat treated material, a sensitizing material and a sensitization restoring material are made by the material of the same quality and shape as those of the target material to provide standard materials. The values of corrosion amount by Heuy test, etc. and the current values by eddy current measurement are beforehand obtained with these and the eddy curent value obtained with the target material is compared with the abovementioned standard materials, whereby the corrosion resistance of the target material is evaluated.

Abstract: PURPOSE: To correct a movable ram always at balance and improve the accuracy of press working by controlling selector valves in accordance with the deformations during working of the movable ram.  
     CONSTITUTION: When a moable ram 7 ascends with upward inclination on the left side on account of occurrence of a difference in the resistances on the right and left sides in its ascending stroke, a torsion bar 25 tries to turn around the pin 29a of a link member 31a and a link member 31b around a pin 29b, but since the left side of the bar 25 is held pulled upward, the bar cannot rotate, and the link member 31b on the left side is pulled upward around the pin 29a of a bracket 37b. Thereupon, a push rod 55b is also pulled up, and this changes over the spool 53a of the 1st selector valve 53 to open the communicating path with a tank 59, thereby stopping the ascending of the fluid pressure operating device 13b on the left side or lowering its speed. On the other hand, the device 13a on the right side continues to ascend and continues to make correction operation until the ram 7 becomes parallel.

Abstract: PURPOSE:To ensure that when a film rewound is to be switched to an advanced position by the normal rotation of a motor, the switching can be achieved by providing an idle coupling to which a motor drive force is not immediately transmitted. CONSTITUTION:An idle gear 95 is disposed in such a manner as to rotate freely and coaxially with a first planetary gear 75 and is meshed with a reel gear 77. A driving pin 75a is placed upright on the first planetary gear 75, a C-shaped groove 95a is cut in the idle gear 95, and the driving pin 75a is inserted into the groove 95a. As a result, while the film is being advanced a first sun gear 66 rotates, and even if the first planetary gear 75, i.e., the driving pin 75a is rotated in the direction of the arrow, the idle gear 95 is not rotated before the driving pin 75a completes approximately one turn and abuts the side wall 95b of the idle gear 95. Therefore, after a rewind mode has been switched to an advance mode and at the initial stages in the advance mode where the meshing of a third planetary gear with the spool gear is not undone, no driving force is transmitted to the reel gear 77, i.e., a reel.

Abstract: PURPOSE:To omit the crosstalk countermeasure which is small-sized, light, at a low cost and between lines by providing a feeding control part and an active low-pass filter which turn ON and OFF the connection of a line voltage detecting resistance and a feeding line. CONSTITUTION:When the pulse of an on/off signal is inputted through a feeding control part 13 to an active low-pass filter part 12, a harmful click component out of the respective even number higher harmonic components is removed from the basic wave to constitute the pulse of an on/off signal.

Further, by a feeding circuit part 11, the electric current of the same waveform as the waveform is supplied to the line. By constitution also the electric power source noise so as to make the output of the filter 12 into the constant electric current control voltage of the circuit part 11, the genaration is prevented. Thus, the crosstalk counter measure is unnecesary which is small-sized, light, at a low cost and between lines.
