Title: Vibration control device for vehicle
Inventor: HAGINO YUKIHIKO
IPC: B60K5/12
Filed: 1985-03-27
Abstract: PURPOSE:To effectively reduce the vibration of a vehicle body, by driving an actuator in accordance with an output waveform which is obtained in accordance with the rotational speed of an engine 1 to apply damping force to the vehicle body, and by comparing the actually measured value of vibration of the vehicle body with a desired value to compensate the output waveform. CONSTITUTION:Waveforms having the same amplitude as that of vibration predicted from the rotational speed of an engine 1 and a phase reverse to that of the vibration are previously stored in a waveform memory means 13. A waveform corresponding to an engine rotational speed obtained from an engine rotational speed detecting device 8 is taken out from the waveform memory means 13, and is issued from a waveform generating means 14. This waveform is amplified by a power amplifier device 10 and then is delivered to an actuator 6 which applies damping force to the vehicle body when it is driven. Further, a desired value for reducing vibration is previously stored in a vibration desired value memory means 12. When an actually measured value of vibration of the vehicle body obtained by a vehicle body vibration detector 5 exceeds this desired value, a stored waveform rewrite means 15 rewrites the content of the waveform memory means 13.

IPC: C22C9/04
Filed: 1984-04-04
Abstract: PURPOSE:To obtain an alloy for a meltable conductor suitable for use as a fusible link by adding a specified amount of tin to 4-6 brass. CONSTITUTION:To 4-6 brass used generally as a material for a casting, a plate, a rod, etc. is added 0.5-3wt% tin. The preferred amount of tin is 0.8-1.5wt% with respect to fusing characteristics and workability. When the amount of tin added is <0.5wt%, the m.p. of 4-6 brass is slightly dropped and sharp fusing characteristics are not attained. When the amount of tin exceeds 3wt%, the mechanical strength of 4-6 brass is reduced and the brass is hardly put into practical use in the field of a traveling car, etc. which are exposed to vibration.

IPC: G03G15/20
Filed: 1988-03-18
Abstract: PURPOSE:To prevent the disturbance of a toner image on a cut sheet in a fixing mechanism section by deformation of a press-contact roller by rotating a heating roller and the press-contact roller to a nip width or above at a specified time interval while the rollers are in a static state. CONSTITUTION:The heat fixing roller 2 and the press-contact roller 3 are rotated to the nip width or above at the specified time interval while the heat fixing roller 2 and the press-contact roller 3 are in the stop state except in a printing state. The contact of the heat fixing roller 2 and the press-contact roller 3 at the same point is thereby obviated and the deformation of the press-contact roller 2 is prevented even if the rollers are held stopped for a long period of time. The load fluctuation of the heat fixing roller 2 and the press-contact roller 3 by the rotation thereof in the printing state is thus suppressed and the disturbance of the toner image on the cut sheet in the fixing mechanism section is prevented.
