Title: Backpost mounting structure for grand piano and method for assembling the same
Inventor: ARIMORI MANABU
IPC: G10C3/06
Filed: 2000-02-14
Abstract: PROBLEM TO BE SOLVED: To prevent the distortion of a backpost even during the transportation, etc., of a piano. SOLUTION: The backpost 12 of the grand piano is fitted into a mortise groove 16 formed at an inner rim 11. An angle parts 16a of the mortise groove 16 are formed into a prescribed radius of curvature. The angle parts 12a of the backpost 12 are also finished by a round cutter, so as to have the radius of curvature as the radius of curvature at the angle parts 16a of the mortise groove 16. Then, when the backpost 12 is fitted into the mortise groove 16, the mortise groove 16 and the backpost 12 come into contact with each other with no clearances. Even if a grand piano body 10 is therefore erected by removing legs, when transporting the piano such a situation that the backpost 12 is distorted like heretofore will not occur and the effect of eliminating the possibility that a deviation arises in the tension of the strings acting on the backpost 12 is obtained.

Title: Liquid crystal display device
Inventor: FUJIKAWA YOSUKE
IPC: G02F1/1365
Filed: 2000-02-15
Abstract: PROBLEM TO BE SOLVED: To arrange dummy pixels for protecting MIM(metal insulator metal) elements of display pixels from the dielectric breakdown due to static electricity generated during a processing without impairing the appearance. SOLUTION: Dummy pixels 10' are provided in a part, which is in the non- display region outside of a display region and which is at a distance from the terminal of the non-display region. In this case, a two-terminal nonlinear element for dummy which is to be formed with one dummy pixel is divided plurally by dividing the electrode which is formed between an insulating film and a first substrate between one pair of electrodes constituting the two-terminal nonlinear element. Thus, since respective dummy pixels 10' are driven separately by two-terminal nonlinear elements 11' for dummy which are to be dielectrically broken down more easily than two-terminal nonlinear elements 4 for display, when they receive static electricity, the two-terminal nonlinear elements 11' for dummy are broken down dielectrically with priority than the two-terminal nonlinear elements 4 for display.

Title: Pneumatic radial tire
Inventor: KOBAYASHI HISANOBU
IPC: B60C9/22
Filed: 2000-02-22
Abstract: PROBLEM TO BE SOLVED: To provide a pneumatic radial tire capable of securing designated residual cornering force while intending for lightening its weight. SOLUTION: In this pneumatic radial tire 10, an inclined belt layer 20A comprising a steel cord and a circumferential belt layer 20B comprising an organic fiber cord are laminated. In the circumferential belt layer 218, a distance L2 from an equatorial plane CL to its left end in the width direction of the tire is larger than a distance R2 to its right end, that is, since it is asymmetrically disposed right and left, rigidity of the tire gets asymmetrical right and left while sandwiching the equatorial plane, and therefore, residual force is produced. Accordingly, a designated residual cornering force can be secured even with a pneumatic radial tire having the circumferential belt layer placed on the furthest outside layer, in order to lighten the tire and therefore, residual cornering force is produced.
