Title: Method and device for sputtering of films
Inventor: KADLEC STANISLAV
IPC: C23C14/34
Filed: 1990-08-13
Abstract: Method and device for layer sputtering Solution relates to sphere of thin layer sputtering, especial-ly titanium-nitride-type hard, abrasion-proof layers.  Ionise-tion current on substrates, especially in greater distances from cathode, is in well-known sputtering  methods weak or non-homogeneous.  The new solution increases density and homo-geneity of both ionization and electron current on substrates and enables ionic cladding during layer sputtering and with floating potential of substrates.  Substrates are placed in holding space defined by lines of force of magnetic multipo-lar field that includes closed tunnel of magnetron-type lines of force above sputtered cathode and whose direction on boun-dary of holding space changes by turns from positive polarity to negative one and vice versa.  Interaction of glow discharge with magnetic multipolar field forms in holding space homoge-neous plasma whose particles bombard substrates.  Degree of plas-ma's holding is controlled by form of magnetic field or by vol-tage on auxiliary cathode that passes through holding space. Device includes sources of magnetic field placed around hol-ding space with alternating orientation.  In order to control degree of plasma's holding the device includes electromagnets or sliding anode extension piece or auxiliary electrode.

Title: Ventilating equipment for railway rolling stock and operating method thereof
Inventor: ISHIKAWA SHINICHIROU
IPC: B61D27/00
Filed: 1991-03-19
Abstract: ABSTRACT OF THE DISCLOSURE      The present invention relates to ventilating equipment for railway rolling stock and an operating method thereof. This ventilating equipment includes a low-pressure supply air blower, a high-pressure supply air blower, a low-pressure exhaust air blower, and a high-pressure exhaust air blower. This ventilating equipment ventilates a car interior during the travel of a train outside of tunnels by means of the low-pressure supply air blower and the low-pressure exhaust air blower.  The car is ventilated during travel in tunnels by means of the high-pressure supply air blower and the high-pressure exhaust air blower.  The high-pressure supply air blower and the high-pressure exhaust air blower produce a higher discharge pressure than a changing external pressure during high-speed travel in tunnels, thereby preventing the propagation of an influence of the changing external pressure into the car interior.  The ventilating equipment is capable of preventing an increase in power consumption of the entire ventilating equipment by interlocking, or changing over, between the high-pressure supply air blower and the high-pressure exhaust air blower and the low-pressure supply air blower and the low-pressure exhaust air blower.

Title: Log skidding vehicle
Inventor: DOYLE JAMES R
IPC: A01G23/00
Filed: 1991-05-31
Abstract: ABSTRACT         A  vehicle  is  provided  for  skidding  timber. Conventional skidders are generally large tracked or rubber tired vehicles having a fixed frame to which a towing cable is attached.   The cable load applied to such skidders is rearward of the rear wheels tending to reduce the load on the front wheels and increase the load on the rear wheels.  A vehicle in accordance with the invention includes a frame pivotally mounted upon the vehicle's chassis.  A cable sheave is mounted upon the outer end of the frame and a towing cable reeved over the sheave with a cable winch attached to the forward end of the cable.  Attachment means secure logs to the end of the cable.  Abutment means connected to the outer end of the frame engage the attachment means as the cable and log are drawn forwardly by the winch.  When the attachment and abutment means engage further winching in of the cable rotates the frame from a rearward position to a forward position.   In the rearward position, the cable sheave is rearward of the vehicle's rear wheels.   In the forward position, the cable sheave is forward of the vehicle's rear wheels.  The load applied by the cable to the vehicle in the forward position is more evenly distributed between the forward and rearward wheels thereby  improving vehicular traction,  reducing rutting of roadways and lessening the tendency of the front wheels to lift from the roadway. Therefore the method and vehicle ensure that the forest may be renewed in perpetuity providing parkland, wildlife habitat and other benefits of nature while also providing employment and forest products in an economically viable quantity.
