Title: Graphic editing device
Inventor: HASEGAWA TAKETO
IPC: G06T11/80
Filed: 1986-09-30
Abstract: PURPOSE:To improve operability in the edition of a graphic by storing the information of one graphic displayed by an instruction means, moving a thinning out pattern formed correspondingly to the graphic by a thinning out pattern forming means by a moving means and plotting by a plotting means based on the graphic information by the storing means after the completion of the movement. CONSTITUTION:At the time of a parallel movement, when the graphic (thick line) is instructed by a pointing device 7, not thickness information but the pattern itself is stored in a memory 8. In order to the number of picture elements, the pattern is plotted at a prescribed interval. In this case, since the pattern constituting the thick line is 5X5 dots, it is desired to have an interval between the central picture elements of four dots or less. During the movement, the movement is displayed with the thinning out pattern, after the movement position is defined, the pattern stored in the memory 8 is reset to a final position and displayed. In such a way, when the thick line is moved, a moving segment is set as indicated in the drawing and the number of the picture elements to be plotted is reduced (thinned out), thereby, a processing speed can be enhanced.

Title: Liquid crystal display device
Inventor: IVAN GEORGE COLGAN
IPC: G02F1/133
Filed: 1999-08-17
Abstract: PROBLEM TO BE SOLVED: To obtain a structure which is suitable for the measurement of the position of contact between a substrate and a human body and integrated in the substrate of an LCD by providing at least one resistor which is integrated between a signal layer and a circuit, arranged integrally on the substrate, and is formed together with the signal layer. SOLUTION: Resistors Ri are symmetrically in the center of a screen and Ri=Rn+1-i. When the screen is linearly correctly, equal potentials are horizontal lines and at equal intervals from the top to the bottom. Specially, the whole upper edge part has a corner part potential +Vm and the lower edge part has -Vm. The current density is proportional to an electric field, which is proportional to the gradient of the potential distribution. Therefore, when the equal potentials are straight lines having equal intervals, the current density is constant crossing the screen and flows vertically from the top to the bottom. Potential variation along a long-side resistor Re accurately matches potential variation in the screen.  This condition is met only when the long-side resistor Re has constant resistance per unit length and the potential at the junction between a corner part resistor Rc and the long-side resistor Re is equal to the corner part voltage Vm.

Title: Method for pickling stainless steel
Inventor: SHIMOMURA TADASHI
IPC: C23G1/08
Filed: 1999-08-17
Abstract: PROBLEM TO BE SOLVED: To increase the life of the treating capability of a pickling soln. by keeping the concentration of the nitride ion not greater than a specified value and to efficiently execute pickling by the reduction of the amt. of acid to be used and the frequency of exchanging a treating soln., in the case stainless steel is pickled with a pickling soln. composed of nitric acid and hydrofluoric acid. SOLUTION: In this pickling method for stainless steel, the concn. of the nitrite ion in a pickling soln. is held to <=0.9 g/L. When the stainless steel is treated with mixed acid of nitric acid and hydrofluoric acid, nitrous acid is produced by the dissolution of the steel. Part of the produced nitrous acid is released to the outside of the system as gaseous NOx such as NO and NO2, and part accumulates in the pickling soln. to hinder the pickling. For reducing the concn. of the nitrite ion, the addition of a compd. which reacts with nitrous acid and the nitrite ion without hindering the pickling or contaminating the pickling bath is an easy way. As the concrete method, the addition of the oxidizer such as hydrogen peroxide, potassium permanganate, ozone, oxygen or air can be given.

Title: Polishing machine
Inventor: KISHI YASUO
IPC: B24B47/10
Filed: 1982-12-22
Abstract: PURPOSE:To enable high efficient polishing to be performed by easy operation, by enabling a polishing machine of metal mold or the like to be selectively operated performing compound action of rotary and horizontal shuttle motions or one of the motions of a polishing tool. CONSTITUTION:If clutches 6, 17 are both engaged, a rotary side driven shaft 10 is rotated to turn a polishing tool 15 on the polished surface W of a work through a main spindle 14, performing rotary polishing motion. While a shuttle slide block 12 performs reciprocating motion in the range of a stroke (b) through a crank 18 and a connecting rod 20 by rotating a shuttle side driven shaft 5, and this causes the polishing tool 15 to perform shuttle movement on the polished surface W while being rotated, thus performing shuttle grinding action. Further by connecting only one of the clutches 6, 17, either one of the polishing works by rotary motion or shuttle motion can be alternatively executed. Accordingly, a polishing machine can both make a contribution to the stabilization of quality of a finished surface such as surface roughness, brilliance, etc. and reduce labor or a polishing time.

Title: Holding device for rod-shaped parts with head
Inventor: SHIMADA TAKAHIKO
IPC: B23P19/06
Filed: 1988-09-14
Abstract: PURPOSE:To enhance the reliability of a holding device by actuating a stopper so as not a jaw to open with a slope piece when a rod-shaped piece of parts with a head is held by the jaw, and releasing the stopper when an attracting pipe attracts the rod-shaped piece of parts. CONSTITUTION:A jaw stopper 8 having a U-shaped groove is fixed to a slope piece 4, and a restriction is made in the condition in which the axis of the outlet from this slope piece 4 with a jaw 5 is identical so that it intrudes into the groove in the jaw stopper 8 not to cause opening. When the slope piece 4 is pressed by an attracting pipe advancing within a Y-pipe 6 and rotated while overwhelming the force of a spring 9, the jaw 5 is released from the U-groove in the jaw stopper 8 and there is no more restriction of opening. This allows weakening of the spring force, which eliminates such inconvenience as wear of the sliding parts of the slope piece 4 with a vacuum pipe to attract rod-shaped parts with head and their hitching, etc.
