Title: Bolt and nut assembling washer and screw type fastener
Inventor: IKETANI KEN
IPC: F16B43/00
Filed: 2000-10-17
Abstract: PROBLEM TO BE SOLVED: To solve the problem that the manufacturing cost of a conventional fitting formed by welding a bolt and a nut to a washer formed with spikes is expensive and that a use of the bolt and the nut is limited. SOLUTION: A washer 1 formed with a bolt insertion hole 3 is formed with three turn stopper claws 7 by cutting and standing them, and formed with spikes 5 projected backward. A distance from the turn stopper claws 7 to the center of the bolt insertion hole 3 is a little larger than a half of a double- surface width B of a bolt head 13 and a nut 17. When seating the bolt head 13, for example, in a front surface 1a of this washer 1, the turn stopper claws 7 come close to a flat side surface 13a or lightly brought in contact with the side wall surface 13a. The spikes 5 work as a turn stopper for the washer 1 itself, and the turn stopper claws 7 of the washer 1 work as a turn stopper for a bolt 11. Since this washer 1 is not integrally formed with a bolt and a nut, manufacturing cost is suppressed, and a use of a bolt and a nut is not limited.

Title: Method and equipment for optical communication
Inventor: YOKOGAWA SEIICHI
IPC: H04B10/516
Filed: 2000-10-30
Abstract: PROBLEM TO BE SOLVED: To reduce the influence of a certain type of optical communication to the other types of optical communications. SOLUTION: When the optical communication is carried out by using a subcarrier to the infrared rays, the direct current light is additionally emitted in a time T1 when no subcarrier exists. The electric power that drives a light emitting element to emit the direct current light is set equal to the electric power that drives the light emitting element in a time T0 when a subcarrier exists. Since the light emitting element is driven, even if the subcarrier does not exist, by the same electric power as that available when the subcarrier exists and can emit the direct current light, a base band spectrum of low frequency that is not needed for the data communication can be reduced.  Furthermore, the unnecessary spectra spreading over and under a subcarrier and the unnecessary spectrum of a higher harmonic can be reduced by dulling the changing point of the direct current light that is additionally emitted or changing the subcarrier into a dull waveform or a sine wave.
