摘要:
A vehicle light can simultaneously form a light distribution pattern for a tail/stop lamp in one direction and another light distribution pattern for a side marker lamp in another direction without use of a dedicated light source(s). The vehicle light can include: a cover lens having a lens portion and a wraparound lens portion extending from the lens portion to the vehicle side face; a first LED light source configured to form first and second light distribution patterns; and a first reflector configured to reflect a first part of light from the first LED light source so as to form the second light distribution pattern. The first LED light source can be disposed so that a second part of the light from the first LED light source passes through the wraparound lens portion to form the first light distribution pattern. The first reflector can be disposed between the first LED light source and the wraparound lens portion so that the first reflector does not block the second part of the light.

In a radially anisotropic sintered magnet of annular shape, the remanence in a radial direction of the annulus increases and decreases at intervals of 90° in a circumferential direction of the annulus, and the remanence in a radial direction over the entire circumference of the annulus has a maximum of 0.95-1.60 T and a minimum equal to 50-95% of the maximum. In a permanent magnet motor comprising a plurality of stator teeth, the radially anisotropic annular sintered magnet is incorporated after it is magnetized in 4n poles (wherein n is an integer of 1 to 20) so that the boundary between N and S poles is located within the range that is centered at the radial direction where the remanence exhibits the minimum and extends ±10° therefrom in a circumferential direction. The radially anisotropic annular sintered magnet undergoes neither fracture nor cracking during the sintering and aging/cooling steps even when it is shaped to a low inner/outer diameter ratio and has satisfactory magnetic properties. A permanent magnet motor comprising the radially anisotropic annular sintered magnet is inexpensive and of high performance.

An optical apparatus is disclosed which includes an integrally-formed rack that can be manufactured easily even when a tooth portion of the rack has a drawing angle with respect to a lead screw. The apparatus includes a holding member holding an optical member, a rack attached to the holding member, and an actuator rotating the lead screw. The rack is integrally formed and includes an attachment portion for being attached to the holding member, first and second tooth portions engaging with the lead screw so as to sandwich the lead screw therebetween, and an elastic connecting portion connecting the attachment portion and the second tooth portion. The second tooth portion is formed to have a gap from the first tooth portion such that the gap is narrowed with distance from the attachment portion. The connecting portion is provided with a protrusion protruding toward the first tooth portion.

A mobile phone of the present invention, which is capable of reproducing a broadcast program supplied through a broadcast wave and stored programs stored in a program data storage, is provided with (i) a program ID extraction section that obtains a broadcast program ID for identifying a supplied broadcast program and a stored program ID for identifying a stored program, and (ii) a program reproduction control section that selects, as a reproduced program, at least one of a broadcast program and stored programs. On this account, a suitable program is selected and reproduced even if a broadcast program is broadcasted in a one-to-many manner. As a result, a suitable reproduced program is selected at suitable timing, in accordance with a supplied broadcast program and stored programs, and hence diversified needs of the users are satisfied.

A method involves the steps of using a mold having a core made of a ferromagnetic material, charging a mold cavity with a magnet powder, compacting the magnet powder while applying an orienting magnetic field according to the vertical compacting in horizontal magnetic field process, and sintering the compact, thereby producing a radially anisotropic annular sintered magnet in which the remanence in a radial direction of the annulus increases and decreases at intervals of 90° in a circumferential direction of the annulus, and the remanence in a radial direction over the entire circumference of the annulus has a maximum of 0.95-1.60 T and a minimum equal to 50-95% of the maximum. A method for preparing an annular multi-pole magnet for a permanent magnet motor involves magnetizing the magnet so that the boundary between N and S poles is located within the range that is centered at the radial direction where the remanence exhibits the minimum and extends ±10° therefrom in a circumferential direction.

The present invention provides a solder ball that has solved the problem of micro-adhesion and, moreover, has solved both of the problems of micro-adhesion and wetting properties, and a method for preventing the micro-adhesion of solder balls. That is, the present invention provides a solder ball obtained by solidification and spheroidization in a gas phase and having metal soap molecules, preferably a metal soap molecules film of 3 nm or less in thickness, adsorbed on its surface. As the metal soap, there can be used, for example, calcium stearate, magnesium stearate or barium stearate. The present invention is preferably applied to solder balls with a diameter of 400 μm or less. The present invention also provides a method for preventing the micro-adhesion of solder balls which comprises immersing solder balls obtained by solidification and spheroidization in a gas phase, in a solution containing a metal soap dispersed therein, preferably, a solution containing a metal soap dispersed therein to a concentration of less than 5 ppm; taking out the solder balls from the solution; vaporizing the solvent on the surfaces of the solder balls; and then drying the surfaces. The drying is preferably conducted in an atmosphere having a relative humidity RH≦40%.
