Title: Toner for development of electrostatic image
Inventor: TAMURA KISHIOMI
IPC: G03G9/08
Filed: 1990-11-29
Abstract: PURPOSE:To prevent blocking and also prevent drop of fluidity and electrostatic charging characteristic due to excessive embedment of inorganic particulates containing Si by specifying the value of toner specific surface area reduction rate within a certain range. CONSTITUTION:The value of toner specific surface area reduction rate Rs as defined by Eq. I shall range from 0.75 to 0.94. The value lying within this range will ensure favorable degree of embedment of Si-containing inorganic particulates in colored resin particles, and therefore it is not likely that the particulates separate off, and further the dropping of the particulate adding effect likely to be caused by embedment will be retarded very much. In Eq. I, Sp is BET specific surface area of toner in m<2>/g, ST is BET specific surface area of colored resin particle before attachment of Si-containing a inorganic particulate in m<2>/g, Ss is BET specific surface area of Si-containing inorganic particulate in m<2>/g, and Xs is share of Si-containing inorganic particulate in the toner in wt.%. This prevents filming over the surface of photo-sensitive body, and it is not likely that toner blocking is generated.

Title: Pallet for arranging parts
Inventor: KAMATANI RYOICHI
IPC: B65G47/14
Filed: 1992-12-08
Abstract: PURPOSE:To permit a pallet to sufficiently cope with a small article part having a long leg part by increasing the arrangement rate of parts by forming a guide groove which extends in the nearly equal width to a part arrangement hole in the direction crossing with the horizontal vibration direction of a plate. CONSTITUTION:On the upper surface of a pallet body 1, a guide groove 3 extending in the nearly equal width to a part arrangement hole 2 is formed in the direction crossing with the horizontal vibration direction of a pallet body 1 from the upper surface opened port of the part arrangement hole 2, and the guide groove 3 is formed deeper toward the part arrangement hole 2 side. Accordingly, a small article part as arrangement objective article which is shifted in reciprocation on the pallet 1 by the horizontal vibration can be easily caught by a leg part. Further, since the center-of-gravity tends to be set close to the part arrangement hole 2 in comparison with the outer edge of the guide groove 3, the arrangement rate can be increased drastically, and the pallet can sufficiently cope with the small article part having the long leg part, different from the conventional method.
