摘要:
This specification discloses an original urging device for enabling an original to be well placed and supported on the original supporting carriage of a copying machine, a printing machine or the like. The supporting member for the original urging plate of the device has one end thereof pivotally supported. A point for taking the resilient force of a resilient member is provided at a point on the supporting member. During replacement of the original, the original urging plate may be made stationary within a predetermined range of angles facilitating the handling of the urging plate, in accordance with the rotated position of the supporting member and by the relationship between the moment produced by the gravity force acting to the supporting member and urging plate and the moment produced by the resilient force of the resilient member.
摘要:
This invention relates to a magnetic recording substance comprising a support and a magnetic layer containing a ferromagnetic metal powder of liquid phase reduction type in a binder, the ferromagnetic metal powder being obtained by mixing an aqueous slurry containing the ferromagnetic metal powder with an organic solvent capable of forming a minimum boiling azeotropic mixture with water and subjecting the mixture to distillation to remove the water.
摘要:
A temperature control method is used for controlling a temperature of an electric storage device 5 mounted on a vehicle 1 at the time when the vehicle 1 runs on a track 2. In the method, when a minimum voltage value Vmin corresponding to an internal resistance R of the electric storage device 5 reaches a first predetermined voltage value Vp near a minimum allowable voltage value VL of the electric storage device 5, the electric storage device 5 is controlled such that the electric storage device 5 has a temperature at which the minimum voltage value Vmin is maintained at the first predetermined voltage value Vp.
