Title: Isothermal forging process
Inventor: CORTI C
IPC: B21J3/00
Filed: 1978-10-26
Granted: 1981-09-28
Abstract: A tool surface is lubricated by high pressure blast spraying a powder lubricant comprising B nitride of particle size 0.6-1.5μ at a spray pressure of 4-5 bar, onto the tool surface.  This produces a high temperature compacted coherent lubricant film on the surface while smoothing, strengthening and compressively stressing the tool surface.  Preferably the powder lubricant comprises 95-5 wt. % B nitride and 5-95 wt. % boric acid or borosilicate glass.  This process gives good wear resistance and good lubricity.

Title: Method of automatically controlling an electrostatic precipitator
Inventor: LEUSSLER WILHELM
IPC: B03C3/68
Filed: 1986-07-25
Granted: 1993-10-09
Abstract: Disclosed is a method for the operation of an electrostatic precipitator so as to provide a pure gas having a predetermined dust content with a minimum consumption of energy. Characteristics for the operation with an unpulsed voltage are recorded for different dust resistivities. Each characteristic has then associated with it that k value with which a pure gas having a predetermined dust can be achieved with a minimum energy consumption. During operation, the actual characteristic is compared with the recorded characteristics and that k value is selected which is associated with the recorded characteristic which coincides with the actual characteristic or is next below the actual characteristic. The actual characteristic is determined in predetermined intervals, the duration of which is determined in dependence on the speed with which the operating conditions may be expected to change.

Abstract: A first I type GaAs layer (23) is formed  on  GaAs  substrate (21) as buffer layer for MESFET (Metal Semiconductor Field  Effect Transistor) and δ-FET (Delta doped  FET)  in  the  preparation  of chemical compound semiconductor element. N- type GaAs  layer  (29) is formed on the surface region (M) of (23) as  active  layer  for MESFET, while delta doped layer (25) and  a  second  I  type  GaAs layer (27) is formed on the region (N). Delta  doped  layer  (25), which is composed of Si, is used as potential well for  generating two-dimensional electron gas. N+ GaAs layer (31) is formed on (29) and (27) as capping layer for MESFET and δ-FET. Source  and  drain electrodes (35,37,39,41) are formed with ohmic contact on (27) and (29).
