A 3D model deformation program is provided capable of performing deformation processing of a 3D model using clusters in each drawing period in a video game. A CPU 21 finds for each cluster with which a vertex is associated the product of a weighting matrix expressing weightings representing the degree of association of a vertex in any desired frame with a cluster with which this vertex is associated, a co-ordinate transformation matrix for transforming the local co-ordinate system of the vertex in this frame to a world co-ordinate system, and an inverse transformation matrix which is the transformation matrix of the co-ordinate transformation matrix for transforming the local co-ordinate system of the vertex in the specified frame to the world co-ordinate system and finds an addition matrix by adding these products.

A spark plug includes: a metal shell defining a front side having an outer periphery formed with a screw section which has a nominal size smaller than or equal to M12; a center electrode; a conductive seal layer; a terminal metal fitting fixed to the center electrode via the conductive seal layer; and an insulator formed with a through hole. The terminal metal fitting has a Vickers hardness in a range from 150-300 Hv. The terminal metal fitting includes: a front end section having an outer diameter, and embedded in the conductive seal layer, and a small diameter section disposed on a rear side of the front end section and having an outer diameter which is smaller than the outer diameter of the front end section. The through hole has an inner diameter different from the outer diameter of the small diameter section in a range from 1.0-1.4 mm.

In a semi-creeping discharge type spark plug, a cylindrical metal shell and an insulator are provided, the latter of which has an axial bore and placed within the metal shell so that a front end of the insulator extends beyond the metal shell. A center electrode is placed within the axial bore of the insulator so that a front end surface edge of the center electrode retracts by 0.1˜0.6 mm behind from a front end surface of the insulator. A ground electrode, one end of which is connected to a front end of the metal shell, and the other end of which is bent to oppose an outer surface of the insulator so as to form an air-gap therebetween while permitting creeping spark discharges running along said front end surface of said insulator. A foward edge portion of a front end surface of the ground electrode extends by 0.0˜1.0 mm forward from the front end surface of the insulator.

A spark plug having a center electrode, a ground electrode, and an insulator. The ground electrode has a firing surface formed in a tip end side, and the firing surface is opposed to a side face of the center electrode. The insulator covers the outside of the center electrode and is placed such that a tip end portion is between the side face of the center electrode and the firing surface of the ground electrode. A discharge high voltage is applied across the center electrode and the ground electrode such that a polarity of the center electrode is positive and that of the ground electrode is negative. The high voltage causes a spark discharge to be generated between the firing surface of the ground electrode and a tip end portion of the center electrode.

An antenna that comprises a rod, a movable coil, and a holding section which holds the movable coil in a manner that allows the movable coil to slide in and out of the holding section. When the movable coil is drawn into the holding section, the holding section tunes to a particular desired frequencies in the upper portion of the VHF band and the UHF band; for example, 144 MHz and 430 MHz. When the movable coil is out of the holding section, the holding section, the rod, and the portion of the movable coil outside the holding section form antenna element of a center-loading type that tunes to frequencies in the HF band and the lower portion of the VHF band; for example, frequencies in the range of 3MHz to 50MHz. The tuning frequency is varied by sliding the position of the coil.

A hydraulic power transmission unit includes a casing connected to an engine, a pump member fixed to the interior of the casing and a turbine mounted within the casing and connected to an output shaft, whereby the output torque of the engine is transmitted to the output shaft through fluid in the casing. A damper mechanism includes damper springs mounted directly on the inner face of the casing at its outer circumference. A damper disc serves to transmit the power of the engine to the output shaft through the damper springs. A lock-up clutch mechanism is also housed within the casing and includes a frictional engagement element arranged between the damper disc and the output shaft. The lock-up clutch mechanism is operated, i.e. frictional engagement element selectively applied and released, by a clutch piston slidably mounted within a cylinder defined by the damper disc.
摘要:
A salt waste composed mainly of chlorides, which is generated from the step of a molten salt electrolytic purification in dry reprocessing of a spent metallic nuclear fuel, is reacted with boric acid at high temperature to convert the chlorides in the salt waste into oxides. The resulting oxides of the salt waste are easily vitrifiable, and a vitrification product is obtained by adding a vitrifying additive to the oxides, heat-melting the mixture to form a molten mixture and cooling the molten mixture.

A polyester is provided that comprises as main monomer components thereof a dicarboxylic acid and a diol, including a p-quaterphenyl derivative of specific formula. The use of appropriate kinds of dicarboxylic acid for the polyester makes it possible to obtain a thermoplastic elastomer or an engineering plastic material (i.e., liquid-crystal polymer).

Rolling element bores are provided in the outer circumferential portion of a disk-like main body. Each rolling element bore has an arcuate outer rim. Rollers each have a groove formed on the peripheral edge and extending along the entire circumference of the roller. The outer rim of each rolling element bore engages with the groove of the associated roller so that the roller is loosely fitted in the rolling element bore. Shafts are respectively formed on both sides of each roller. The shafts project from the center of the roller. An elastic ring is mounted on each shaft. Annular guide plates are respectively mounted on both sides of the disk-like main body so that the shafts of the rollers are supported by the guide plates.
