Title: Wiring board and illuminator
Inventor: KOBAYASHI KATSUYUKI
IPC: H05B41/00
Filed: 2000-04-28
Abstract: PROBLEM TO BE SOLVED: To provide a wiring board with reduced noise. SOLUTION: High-frequency noise generated at an inverter circuit 30 is prevented from returning to a power supply line, by grounding leaked part of noise generated at the inverter 30 to the illuminator main body by a noise absorbing pattern 14. High-frequency noise at a high-frequency output terminal 36 is also prevented from returning to the power supply line by grounding to the illuminator main body by the noise absorbing pattern 14.  As high-frequency noise is already removed at a filter part 20, by connecting from an opening 15 of the noise absorbing pattern 14 to a power input terminal 13 through insertion, the part between the filter part 20 and the power input terminal 13 does not intersects the noise absorbing pattern 14, therefore, while preventing high-frequency noise from leaking into the power input terminal 13 and a power supply line 2, the insulation treatment between the noise absorbing pattern become unnecessary.

Filed: 2000-04-28
Abstract: PROBLEM TO BE SOLVED: To easily keep a position at an arbitrary angle in the opening and closing of a lid member with approximately constant frictional force by determining a surface hardness of a rotary shaft of a shaft member within a range above a specific value. SOLUTION: A shaft member 10 is provided with surface hardness Hv (Vickers hardness) of above 800 by being made out of an age-hardening type SUS material, a high Si aluminium alloy and the like. When the surface hardness Hv of the shaft member 10 is low, the entanglement in an initial period of its rotation is increased, and the stick-slip is increased, and when the surface hardness Hv is high, the engaglement in the initial period of its rotation and the stick-slip can be decreased. In an experimental view, as a point of inflection having a maximum value, is found in a zone of the surface hardness Hv of 700-750, a friction hinge device 1 can exercise the superior function in the practical use when it has the surface hardness Hv not less than 800.
