Title: Magnetic toner process cartridge and image forming method
Inventor: KATADA MASAICHIRO
IPC: G03G9/083
Filed: 1998-12-08
Abstract: A magnetic toner is formed from a binder resin and silicon-containing magnetic iron oxide particles. The magnetic toner has a weight-average particle size of at most 13.5  mu m, and the magnetic toner has a particle size distribution such that magnetic toner particles having a particle size of at least 12.7  mu m are contained in an amount of at most 50 wt. %. The magnetic iron oxide particles have a silicon content of 0.4 - 2.0 wt. % based on iron, and the magnetic iron oxide particles have an Fe/Si atomic ratio of 1.2 - 4.0 at the utmost surfaces thereof. Because of the use of such magnetic iron oxide particles having a specifically controlled overall and surface Si contents, the magnetic toner can show stable performances even after standing in a high humidity environment. <IMAGE>

Abstract: PCT No. PCT/CH97/00055 Sec. 371 Date Oct. 5, 1998 Sec. 102(e) Date Oct. 5, 1998 PCT Filed Feb. 18, 1997 PCT Pub. No. WO97/37922 PCT Pub. Date Oct. 16, 1997The invention concerns a control system for a plurality of groups of lifts (G1-G5), according to which system the passenger can input his destination at any destination call input device (TE) without having to know which group of lifts (G1-G5) serves the desired storey. In this way, in large buildings in which, for structural reasons, the ranges of storeys served by individual groups of lifts (G1-G5) are disposed adjacent one another in a confused manner, the passenger's search for the appropriate lift is facilitated. The multiple groups control system always selects the most favorable lift from all the available lifts and, when the storey ranges served by a plurality of groups of lifts (G4-G5) overlap, the selection is made from all the possible lifts. If the passenger has to change lifts, the connecting lift is shown on a display.

Title: Method of making road vehicles wider
Inventor: MLAKAR EMIL
IPC: B62D65/00
Filed: 1995-06-23
Abstract: A procedure for the construction, making and remaking of road vehicles in accordance with the invention makes it possible to increase the width of road vehicles, in particular standard-make road vehicles. The procedure in accordance with the invention is based on an asymmetrical extension whereby all vital parts of the driver's surroundings (steering, control assemblies and the parts of the driver's position) are kept unchanged, and need not be altered or remade. In this way the design, making and remaking are facilitated and an extension of the useful space is obtained. The procedure for the construction, making and remaking of extended road vehicles in accordance with the invention consists in keeping the vital assemblies (the driving and control assemblies) and the driver's working surroundings in their original dimensions and installation, while carrying out the extension by introducing, symmetrically or asymmetrically, or by a combination of both, an insert into the longitudinally extended vehicle. Such a construction, making and remaking keeps, essentially, all the vital parts of the original road vehicle (the control and driving parts remain unchanged). The steering wheel, the driver's surroundings with the seat and the distance between the wheels or the clamping of the front wheel remains, in any case, in the same relationship as in a series-produced, non-extended vehicle, regardless of the right- or left-hand installation of the steering wheel, or of the right- or left-hand installation of the engine.
