Patent number: 10504694Abstract: A scanning electron microscope comprises three objective lenses, including a distant objective lens and a close objective lens, which are of conventional type, and an immersion objective lens of the immersion type below the distant objective lens and the close objective lens. These three objective lenses can be controlled independently, therefor different combinations of active objective lenses can be achieved. The scanning electron microscope therefore offers various imaging modes. There is a possibility to switch between these imaging modes and therefore, choose the most suitable way of imaging for given application.Type: GrantFiled: May 22, 2017Date of Patent: December 10, 2019Assignee: TESCAN Brno, s.r.o.Inventors: Jaroslav Jiruse, Filip Lopour, Milos Havelka, Jan Polster, Josef Rysavka, Martin Zadrazil

Publication number: 20150209841Abstract: A method for the treatment of inner surfaces of vacuum components and the device for carrying it out which enables the reduction of undesirable organic and inorganic contamination of vacuum systems not only in those that are being produced, but also enables the reduction of contamination in systems that are already in use, such as SEM, TEM, SEM-FIB, XPS, MALDI, SIMS and other analytical and inspection techniques. The proposed method for contaminant treatment derives benefit from a photocatalytic process, which is actually a chemical decomposition of contaminants using a photocatalytic material and electromagnetic radiation, the photocatalytic material being cooled simultaneously to a low temperature. The photocatalytic material is applied to the walls of the vacuum system or vacuum units, which are included in the system, in the form of a layer.Type: ApplicationFiled: January 29, 2015Publication date: July 30, 2015Inventors: Pavel STAHEL, Mirko CERNAK, Zdenek NAVRATIL, Jaroslav JIRUSE, Jiri FIALA, Martin HANICINEC

Patent number: 4786043Abstract: Feeding device for feeding paper sheets from a pile, particularly in offset printing machines. The device has a driving mechanism, the operation of which is controlled by three sets of two cams in precise intervals according to the program of operation of the printing machine. All control mechanisms have their operation motions designed separately in such manner, that each mechanism is controlled by one set of two cams. The advantage of the said feeding device consists in that the control mechanism perform precise operations in accordance with the program of operation even at high printing speeds, because they are controlled bilaterally by the set of two cams and double rollers without employing spring elements to cause cam followers to remain in contact with cam surfaces.Type: GrantFiled: October 10, 1986Date of Patent: November 22, 1988Assignee: ZVS - Adamovsky strojirny koncernovy podnik AdamovInventors: Jaroslav Jiruse, Milan Konecny, Vladimir Drlik

Patent number: 4736938Abstract: An improved suction feeder, particularly for printing machines is disclosed, wherein higher feeding and printing speeds are made possible.The main features of the invention is that in the body of the suction feeder is a small conduit channel and an air filling small channel which connect an inleading small channel for the bringing of pressurized air into an empty space over a small piston. In the said small conduit channel is formed a pressure spring in the upper part of said small conduit channel, and a seat in which a small ball is placed on the other end. The above described suction feeder works on the principle of the difference of air pressure above and below the small piston. While individual paper sheets are being lifted from a pile of sheets, the pressurized air is led into the empty space over the small piston, by which it instantaneously neutralizes the remaining depressurized air, leading to an instantaneous loosening of the paper sheets.Type: GrantFiled: November 7, 1985Date of Patent: April 12, 1988Assignee: ZVS Adamovske strojirny, koncernovy podnikInventors: Jaroslav Jiruse, Milan Konecny, Vladimir Drlik

A single mechanism controls the single functions of the printing mechanism, such as the bringing into pressure engagement and the disengagement of the printing cylinders, the control of the inking unit, the control of the numbering device, and also possibly of other mechanisms. Around the circumference of a double-cam, there are arranged a plurality of two-arm levers. A first two-arm lever, which is pivotally arranged on a fixed, pivot pin is connected by means of a first pull rod with the mechanism of the inker unit. A second two-arm lever is journalled on a second fixed pivot, the second two-arm lever being connected by means of a second pull rod with a mechanism for imposing printing pressure and releasing such printing pressure.Type: GrantFiled: November 8, 1984Date of Patent: September 3, 1985Assignee: ZVS Adamovske strojirny, koncernovy podnikInventors: Vaclav Sedlak, Jaroslav Jiruse

Patent number: 4488484Abstract: Control device for the offset cylinder of an offset printing machine, said control device selectively governing the movement of the offset cylinder into printing engagement with the plate and impression cylinders of the printing machine and the movement of the offset cylinder away from said plate and impression cylinders to relieve them of printing pressure. The control device mounts the offset cylinder sufficiently stiffly in the frame of the printing machine so as to avoid faults in the printing as, for example, the formation of strips on the printed paper sheets. The offset cylinder is rotatably mounted on an eccentric shaft which is mounted in first adjustable bearings which are arranged in eccentric bushings. On said eccentric bushings there are mounted second adjustable bearings which are arranged in bearing flanges which are adjustably fastened in the side walls of the printing machine.Type: GrantFiled: June 1, 1983Date of Patent: December 18, 1984Assignee: ZVS Adamovske strojirny koncernovy podnikInventors: Jaroslav Jiruse, Zbynek Liska
