Title: Platinum alloy for accessory
Inventor: TAMEMASA HIROSHI
IPC: C22F1/14
Filed: 1981-03-03
Abstract: PURPOSE: To obtain a Pt alloy for an accessory with superior mechanical  strength and workability by preparing an alloy consisting of specified amounts  of Pt and Sn.  
     CONSTITUTION: The composition of a Pt alloy for an accessory is composed of 90W98w/o Pt and 2W10w/o Sn. The reason for the addition of Sn is that Sn shows remarkable age hardenability by aging at a suitable temp. after soln. heat treatment by heating to the solid soln. range and quenching, yet <2w/o Sn improves hardly the hardness, and >10w/o Sn increases the amount of intermetallic Pt-Sn compound and deteriorates the workability.

Abstract: PURPOSE:To shorten the copying time of an electrophotographic copying machine which measures original density at intervals of a specific number of sheets and controls copy density, by omitting measurement when the remaining number of copies to be taken is smaller than a specific value. CONSTITUTION:The potential of an electrostatic latent image obtained by projecting an image of an original 109 upon a photosensitive drum 114 is detected by a sensor 123 before the 1st copy is taken, and the value is integrated while the photosensitive surface is passed by the length of the original. A value on which the mean original density is reflected is digitized and a corresponding lamp illumination value is read out of the table in a control circuit 121 to control a lighting circuit 124 by an image exposing circuit 122, thus adjusting the brightness of a lamp. A measurement of the original density is taken repeatedly every time 20 copies are taken, and constant illuminance is held during the period. When the remaining number of copies to be taken is >=20, the measurement is not performed repeatedly and copying operation is carried on with the illuminance based upon the last measured value.
