Title: Liquid crystal element
Inventor: TSUBOYAMA AKIRA
IPC: G02F1/1368
Filed: 1998-12-17
Abstract: PROBLEM TO BE SOLVED: To shorten a time, or to lower a voltage, required for a bend alignment treatment in an OCB(Optically Compensated Bend) mode liquid crystal element. SOLUTION: In a nematic liquid crystal layer alumina particles with their diameter smaller than the liquid crystal layer thickness are incorporated. Thereby in the case a voltage to bend is applied to the liquid crystal layer in splay alignment, probability of nucleus generation in a bend alignment region increases so as to convert the element as a whole into the bend alignment region within a short time. Furthermore, as the volume resistivity of the liquid crystal layer increases by incorporating the alumina particles so as to substantially increase the efficient voltage applied to the liquid crystal layer, an equal effect is obtained with a lower voltage to bend.

Title: Driving device and robot device
Inventor: YAMAGISHI KEN
IPC: B25J19/00
Filed: 1996-12-29
Abstract: PROBLEM TO BE SOLVED: To attain size reduction and weight reduction in a driving device by arranging a rotary member which converts driving force imparted to a driving object member into torque by rotating the driving object member in the direction according to the driving force and transmits the torque to a connecting part of a part. SOLUTION: When a plate member 28 is driven in the lengthwise direction of a belt 25 by elliptic motion generated on the tips of projecting parts 26D and 26E of an elastic member 26A, pulleys 21 and 23 rotate the belt 25 in the lengthwise direction of the belt 25. Therefore, the elliptic motion transmitted to the plate member 28 is converted into rotary motion, and a thigh part unit 11A can be relatively rotated to a neck part unit 11B by the rotary motion. Rotating speed and torque are adjusted only by changing a diameter of the pulleys 21 and 23 without using a speed reduction mechanism in a leg part 11.

IPC: B41J2/455
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of stably forming a dot by preventing occurrence of vertical stripes in an image even when optical quantity distributions of LED elements are varied or focal depths of lens arrays are varied. SOLUTION: In this image forming apparatus, a lens array 13 is provided at a defocus position with respect to an LED array 12 and an image forming face on a photosensitive body 10. In this condition, the optical quantity distribution is likely expanded compared to a condition that the lens array is provided to a focus position. However, as the degree of the variation in the optical quantity distribution due to variation in focal depth of the lens array 13 becomes small, the optical quantity distribution of each LED element tends to be extended, but the variation therein is reduced as a whole and occurrence of vertical stripes in the image is prevented.

Filed: 1992-12-28
Abstract: PURPOSE:To form a film having excellent adhesion to an org. coating layer by impressing a square wave potential to a stainless steel immersed into an electrolytic bath. CONSTITUTION:The square wave potential having the amplitude between a base potential range EL from a natural potential E1 of Cr to a passivation initiation potential E2 of the Cr and a noble potential range EH from a passivation initiation potential E3 of Fe to a potential E4 at which the overpassivation dissolution current of the Cr is increases drastically is pressed to the stainless steel immersed into the electrolytic bath to form a film contg. chromium hydroxide on the surface of the stainless steel; thereafter, the passivation is subjected to a coating type chromate treatment. As a result, the metal ions eluted from the stainless steel by the electrolysis in the noble potential range EH are deposited on the surface of the stainless steel by the electrolysis in the base potential range E1, by which the film is formed. The Cr contained in the stainless steel migrates as the hydroxide to the film in the process of such elution-precipitation. The surface layer having high affinity to rubber, resin, coating material, etc., is thus obtd.
