Title: Production of silver powder
Inventor: KONISHI NOBORU
IPC: B22F9/24
Filed: 1994-09-28
Abstract: PURPOSE: To produce a monodisperse silver powder narrowed in particle size distribution and having a specified average particle diameter by adding a silver nitrate soln. to the mixed soln. of ammonium sulfite, aq. ammonia and hydroquinone to bring about a reaction at a specified temp. CONSTITUTION: The mixed soln. of ammonium sulfite, aq. ammonia and hydroquinone is used as a reducing agent soln., a silver nitrate soln. is used as a soln. contg. silver ion, and the soln. contg. silver ion is added to the reducing agent soln. so that the reaction temp. is controlled to <=50 deg.C. In thus case, 0.2-1mol of hydroquinone per mol of silver, 1-12mols of ammonium sulfite and 0.1-1 mol of aq. ammonia, expressed in terms of ammonia, are preferably used.

Title: Apparatus for measuring charge quantity distribution of one-component type toner
Inventor: TAKAGI SEIICHI
IPC: G01R29/24
Filed: 1990-09-05
Abstract: PURPOSE:To efficiently measure the charge quantity distribution of charged toner particles with high accuracy by collecting said toner particles by applying an alternating electric fields having different duty ratios across a toner particle support member thinly coated with one-component toner and an opposed electrode. CONSTITUTION:A toner particle support member 2 has one-component type toner particles 1 and a conductive member and a prescribing member 4 is formed by thinly coating the member 2 with the particles 1. When alternating electric fields having different duty ratios are applied, the particles 1 are peeled from the member 2. In this case, since the particles 1 have either one of positive and negative polarities, when only a DC electric field is set to a separation electric field, only the particles 1 offset to one polarity can be collected and the aggregations of the particles are hard to separate and, therefore, by the use of the alternating electric fields having different duty ratios, tribo-electric quantity is increased and aggregations are made easy to loosen with respect to the particles 1 of both positive and negative polarities and efficient and highly accurate measurement can be carried out regardless of the offset of the chargeability of the particles 1 and the form and operation of the members 2.
