IPC: H01H25/00
Filed: 2002-04-12
Abstract: <P>PROBLEM TO BE SOLVED: To provide a cover member for a lighted push-button switch, which is inexpensive and has high luminance.  <P>SOLUTION: In this cover member for the lighted push-button switch, a display 17 is arranged in a resin key-top 12, and emits the light from the inside while receiving the light from an inner light source 14b which is arranged in a lower position. The resin key-top 12 is joined to a key-sheet 13. The key-sheet 13 is made of thermoplastic elastomer as a lightproof material, and a light transmitting opening part 13f is arranged in the key-sheet 13 so that bottom side of the resin key-top 12 is exposed to the inner light source 14b. Consequently, there is no light leakage from the key-sheet 13, and additionally, the light from the inner light source 14b does not pass through the key-sheet 13 and can directly reach the bottom side of the resin key-top part 12 without dimming the light. Hence the display 17 of the resin key-top part 12 can be illuminated with high luminance.  <P>COPYRIGHT: (C)2003,JPO

Title: Rotor of motor
Inventor: SHIBATA YOSHIYUKI
IPC: H02K1/27
Filed: 2002-04-15
Abstract: <P>PROBLEM TO BE SOLVED: To efficiently and easily form a strong magnetic flux distribution around a rotor.  <P>SOLUTION: The thickness of a ring magnet 2 is about 2 mm, and the diameter of a shaft 1 is about 50 mm. The thickness of an epoxy bond 3 is about 15 μm (1/6 or less of conventional value). Both are bonded together, resulting in the magnetic resistance at the bonding part being 1/6 or below of conventional value. A slit 4 is provided at an intermediate point between an N-pole magnetized part and an S-pole magnetized part, with the slit 4 being almost V-shape. Thanks to this shape, a stress is effectively concentrated on a point directly under the tip of V-shape. Almost no magnetic flux leaks at the point on the outer periphery of the ring magnet where a magnetic flux density is almost zero even if a crack occurs, with little effect on the magnetic flux distribution. So, if the slit is provided to such part as the magnetic flux density is almost zero, the part that can cause cracking is limited to the slit position, and no output torque is dropped nor cogging torque is increased even when a cracking occurs.  <P>COPYRIGHT: (C)2004,JPO

Filed: 2002-04-23
Abstract: <P>PROBLEM TO BE SOLVED: To efficiently apply a stable magnetic field to a recording medium even when a magnetic head slider is inclined.  <P>SOLUTION: A coil is formed to be wound from the outer periphery to the inner periphery in the counter-clock-wise direction. An opening is formed in the middle of the coil. The line width of the coil is set to be large on the flow-in side of air and to be small on the flow-out side of air. Namely, the line width on the side of an air flow-out end is smallest when it is watched from the middle of the opening, and the line width on the side of an air flow-in end is largest when it is watched from the middle of the opening. The line width of a lateral portion located between the air flow-in end side and the air flow-out end side is set to be medium between the line width on the air flow-in end side and the line width on the air flow-out end side. Such a coil is arranged near the air flow-out end of the magnetic head slider. Thus, a distance between the air flow-out end of the magnetic head slider and a peak position of a generated magnetic field is reduced.  <P>COPYRIGHT: (C)2004,JPO
