Title: Method and equipment for measuring the flow rate, particularly in connection with control of the spray pattern of farm sprayers
IPC: G05D7/00
Filed: 1988-01-27
Abstract: This invention concerns, in brief, means of and devices for measuring the flow rate of liquids, as well as equipment for controlling the spray patterns of farm sprayers in which measurements of flow rate according to the invention are included. The liquid to be measured is led into a measuring cylinder (8) whereby the level of the liquid in the measuring cylinder provides a measure of the flow rate. By keeping the level (9) constant by means of level sensors (10) and a control unit (12), together with a pump (12) governed by the control unit, the liquid is pumped through a flow meter (14) which, without losses, gives a rapid and reliable measurement of the flow rate. This method of measuring the flow rate is utilized in equipment consisting of a trolley, which runs on a track and which collects in a collection channel the spray emitted from nozzles. The part of the spray liquid which is caught by the collection channel is measured with regard to flow rate and these measurements are done either stepwise or continuously along the nozzle boom, whereby a total picture of the sprayer's condition is obtained.

Title: Method of testing conductor film quality
IPC: G01R31/26
Filed: 1989-04-18
Abstract: A method of testing the quality of a conductor 
film laminated onto a surface of a substrate, is carried 
out by the steps of mounting a testing stand (8) having 
a T-shaped cross section on the surface of the substrate 
(1), the testing stand (8) being provided with an undercut 
portion (9) around the entire periphery thereof, 
laminating a conductor film (10b) having a predetermined 
thickness on the surface of the substrate (1), and forming 
on the top surface of the testing stand (8) a wiring 
pattern (4) formed with a conductor film (10a) insulated 
from the first mentioned conductor film (10b) laminated 
onto the substrate (1). An electric current is then 
applied to the wiring pattern (4). Characteristics 
testing of the conductor film can therefore be performed 
immediately after the laminating of the conductor film 
to significantly reduce the testing time.

Title: Stand-by mode setting/releasing device for video cassette recorder
IPC: G11B15/665
Filed: 1989-04-27
Abstract: When the attachment of the video cassette to a VCR is 
terminated, a microcomputer drives a cylinder motor 
immediately to execute tape loading. In the stop state, 
with the tape loading completed, cylinder rotation is 
continued for 5 minutes without tensioning the tape and 
cylinder rotation is terminated after lapse of the 5 
minutes. In this manner, other modes in the stop mode can 
be set quickly, while power consumption is also avoided. 
When there is no necessity of maintaining channel 
selection at the VCR tuner, tape loading and power 
turn-off may be executed after lapse of the five-minute 
period to further reduce the power consumption.

Title: Apparatus and methods for optical emission spectroscopy
IPC: H03K3/57
Filed: 1990-04-23
Abstract: A spark generator suitable for use in an optical 
emission spectrometer, and capable of generating a spark in 
a spark gap formed between an electrode and a sample to be 
analysed, comprises means for generating a current of 
programmable amplitude in the spark gap in each of a series 
of discrete time intervals.  
     The spark generator according to the invention is 
advantageous when compared with conventional spark 
generators in that it enables a higher degree of choice and 
control in the form of the spark. In particular, it 
enables the amplitudes of various portions of the spark to 
be independently varied, thus permitting the shape of the 
spark to be tailored to the particular analysis being 
performed.  
     Also described are methods of optical emission 
spectroscopy which make use of the advantageous properties 
of the spark generator.
