Abstract:
In a method of manufacturing a brake disc having an outer peripheral shape of projections-recesses repetition in which a radial projection and a radial recess are alternately repeated in the circumferential direction of the brake disc, there is provided a method in which a curved face portion can be formed uniformly over the entire outer peripheral edge portion of the disc main body so as to eliminate the step of chamfering for removing burrs and which is superior in productivity. A disc main body whose outer peripheral shape is projections-recesses repetition is half-blanked from one of plate thickness directions of a sheet material. Thereafter, the disc main body is blanked from the other of the plate thickness directions of the sheet material W. At an outer peripheral edge portion of each surface in said one and the other of the plate thickness directions of the disc main body manufactured by this method, there is formed a curved face portion, due to sagging, on the disc main body 1 in a manner to be in continuation of the sheared portions on an outer peripheral surface of the disc main body. The inner diameter R11 of the die to be used in the half-blanking step is configured to be slightly smaller than the outer diameter R12 of the punch.
Abstract:
A rotary electric machine includes a rotor core, a stator, a field yoke, and a field winding. The rotor core is fixed to a rotary shaft, which includes a magnetic body for forming a magnetic path, and magnetic salient poles. The stator has teeth and a stator winding wound around the teeth by concentrated winding. A slot is formed between adjacent ones of the teeth in a circumferential direction. The field yoke magnetically connects the stator and the magnetic body. The field winding is located in proximity to at least one of the winding ends of the stator winding in an axial direction of the rotary shaft. The field winding generates a magnetic pole on the magnetic salient poles when energized.
Abstract:
An object of the present invention is to provide a three-dimensional image recording medium in which three-dimensional information of a recorded material is recorded precisely and observed more naturally. The linear images of plural parallel-projection images from different directions A to E divided into rectangles are recorded sequentially to divisional recording units of the linear image recording units M1 to M8 and in addition, the linear images of divided parallel-projection images from the same direction are recorded sequentially to each divisional recording unit arranged in the same position relative to a lens width direction of each lenticular lens unit L1 to L8 corresponding to each linear image recording unit M1 to M8 to thereby reproduce a three-dimensional image by combining the linear images of plural parallel-projection images.

Abstract:
A ceramic-metal assembly including: a ceramic base; an electrode pad provided on a surface of the ceramic base; a connection terminal for external electrical connection; and a joining portion which joins the connection terminal to the electrode pad. The electrode pad has a first layer which is in contact with the ceramic base and a second layer which is in contact with the joining portion. The first layer contains 20 to 50 vol % of a ceramic component, and the second layer contains a component of the joining portion.
Abstract:
In an evaluation device and an evaluation system, the level of base power is set higher than that in an optimal recording condition at a set room temperature and lower than the level of bias power. In particular, the level of the base power is set so that the jitter value of a recording mark and a blank, which is formed in a required high temperature environment, during reproduction in the high temperature environment becomes minimum. By evaluating the recording characteristic of a recording mark and a blank formed by irradiation of recording laser light in the form of a pulse train, the recording characteristic of an optical recording medium in high-speed recording in high temperature environment is evaluated.
Abstract:
A door assembly allows one to easily and freely change a hinged side and an opening direction of a door when or after a resident moves into a house. Detachable inner frames having doorstop portions, flat portions, and locking nails are mounted to locking grooves in left and right vertical outer frames around spacers and a door main body is mounted to a heelpost side flat portion through hinges. By dividing a doorframe into the vertical outer frames and the inner frames, in order to change a hinged side of the door, the inner frames are pulled out from the vertical outer frames and inserted into the locking grooves in the vertical outer frames after changing orientation of the inner frames according to the hinged side or exchanging the inner frames for the inner frames suitable for the hinged side and the opening direction to thereby easily change the hinged side of the door main body.

A computer program product for causing a computer of an information processing device to execute processing for generating a sound that is generated by a mobile object with a plurality of tires, which moves on a predetermined surface within a virtual three-dimensional space, the computer being caused to execute the steps of: controlling the movement of the mobile object; calculating a load applied to at least one of the tires of the mobile object; controlling, on the basis of the load, a volume and a pitch of a squealing sound generated from the tires; and outputting the squealing sound. The computer is further caused to execute the steps of calculating a slip angle of at least one of the tires of the mobile object, and changing the tone of the squealing sound on the basis of the slip angle.
Abstract:
A rewritable phase-change optical recording medium is provided, which includes a substrate, a first information layer, a spacer layer, a second information layer, and a cover layer. The second information layer includes a recording film containing Sb as a main component and V or V and In as second components. When an amorphous mark formed in the recording film is irradiated with a reproduction beam, crystallization of the amorphous mark occurs only in a central portion in the width direction of the amorphous mark. The width direction is orthogonal to the scanning direction of the laser beam. The recording film is formed of a material that exhibits a change in degree of modulation of 5% or less when recorded information is repeatedly reproduced. The change in degree of modulation is a change from when the number of times of reproduction is 100,000 to when it is 400,000.
