A disk brake comprises a caliper including a claw portion, a pair of pads including back plates, a pin slidably supporting the pads, and a clip for preventing removal of the pin from the disk brake. The claw portion includes at its side end a first extension. One of the back plates includes at its side end a second extension. The clip is provided between the first and second extensions. The first and second extensions are of such a size as to cover the clip. The first extension includes a projecting portion for covering the upper side of the clip. The first and second extensions and the projecting portion cover the clip so that locating the clip from the outside of the disk brake is difficult, thus preventing removal of the clip.

A urethane prepolymer composition useful as sealant is disclosed. The composition comprises a reaction product of an organic polyisocyanate and a polyether polyol mixture at an NCO/OH equivalent ratio from 1.6 to 2.5. The polyether polyol mixture contains (a) from 75 to 95 % by weight of the mixture of a polyoxyalkylenediol having an average MW from 400 to 1,000 and an oxyethlene unit content greater than 50 % by weight, and (b) the balance of the mixture of a polyoxyalkylenetriol having an average MW from 5,000 to 10,000 and an oxyethylene unit content greater than 50 % by weight. An equivalent composition is produced by reacting the polyoxyalkylenediol and polyoxyalkylenetriol with the organic polyisocyanate separately and mixing together after the reaction.

A multi-player type video game playing system permits a plurality of players to play and enjoy a game within the common game space. The video game has a cylinder-shaped screen; a plurality of projectors arranged and allocated to project a game scene continuously extending around the entire circumference of the cylindrical screen; a plurality of players' operating sections arranged radially toward the screen; and an image processor for computing a game scene to be projected onto the screen in accordance with input signals from the players' operating sections and a predetermined game program. The image signals representative of the computed game scene are supplied to the projectors to form the game scene continuously extending around the entire circumference of the screen, whereby any one of the players can face and observe a transversely widened game scene covering the entire field of view for that player such that all the players can enjoy the game with increased reality.

According to an embodiment, two or more sets of knead forging are performed where one set is cold forging processes in directions parallel to and perpendicular to a thickness direction of a columnar titanium material. The titanium material is heated to a temperature of 700° C. or more to induce recrystallization, and thereafter, two or more sets of knead forging are performed where one set is the cold forging processes in the directions parallel to and perpendicular to the thickness direction. Further, the titanium material is cold rolled, and is heat-treated to a temperature of 300° C. or more.

A motion detection portion of a video encoding apparatus conducts motion detection on each of frame macroblocks and field macroblocks to calculate motion vectors and respective detection cost. A motion vector evaluation value calculation portion calculates an evaluation value of the size of motion vectors. A motion vector threshold determination portion compares the evaluation value of the size of motion vectors to a predetermined threshold to determine whether the target area is a moving area or a still area. If the target area is a moving area, it is determined whether frame or field macroblock mode is to be used by comparing the detection costs. If the target area is a still area, it is determined whether frame or field macroblock mode is to be used in accordance with the size of the sum of absolute values of differences between neighboring pixels in a vertical direction regarding the frame macroblock and field macroblock.
摘要:
A valve-integrated transponder includes an air valve and a casing that are integrated with each other, and is disposed within a tire. The casing houses a substrate having a detecting element mounted thereon, an inverse F antenna element, and a supporting member. The antenna element has a substantially line symmetrical shape where a pair of radiation conductors extend away from each other. A longitudinal direction of the substrate is substantially perpendicular to an axial direction of the air valve, and a lateral direction of the substrate is inclined relative to a well of a wheel rim. The two radiation conductors of the antenna element disposed on the substrate are inclined at a predetermined angle with respect to the substrate, so as to be disposed substantially in parallel to the well that extends at the inner side of the transponder as viewed in the radial direction of the tire.
