Title: Method of controlling the relative humidity in soil environment
Inventor: DRNSTEIN LEONARD
IPC: A01G25/00
Filed: 1979-06-16
Granted: 1983-09-12
Abstract: A method of controlling water supply for each plant or many plants is described.  In gardening, controlling the quantity of water supply is required according to the plant type, growth rate, air flow rate around the plant, relative humidity, and drainage.  When relative humidity in soil is to be permanent wilting potential state, plants will be perished lack of water, and down to -10-5 bar.  For the maximal plant growth and minimal pressure, metric potential of soil water must be maintained<-0.3 bar, and soil must not be sunken and keep up >-6 bar.  Thus, this system control the relative humidity in soil by perceiving osmotic pressure automatically.

Title: Ac motor speed control system
Inventor: KURAKAKKE MITSUO
IPC: H02P29/00
Filed: 1982-06-07
Granted: 1988-08-24
Abstract: The speed of an induction motor is controlled by an AC voltage based on a speed command signal (VCMD) in the form of an analog voltage. The actual value of the rotational speed (TSA) is fed back to the input side of the control network.  The VCMD and TSA signals feed into an adder subtractor to produce an error signal ER indicative of the difference and representing the motor slip.  The error signal ER is applied to a proportional integrating circuit, a polarity discriminating circuit and also applied to an absolute value circuit with the output going to a voltage-to-frequency converter producing a pulse train in which the frequency is proportional to the error signal magnitude.

Abstract: The present invention relates to a method of and an apparatus for manufacturing biaxially oriented film. A tubular original film which has been extruded by an extruding die is biaxially oriented by heat and air injected to the inside portion thereof being conveyed to nip rolls each having an individual circumferential speed. The temperature of heat to be applied to the film is controlled on the basis of the detected film thickness for the purpose of obtaining a uniform film thickness distribution. Furthermore, the film can be made uniform by adjusting the outer diameter of the bubble-shaped oriented film by adjusting the distance between two sets of nip rolls on the basis of the measured width of the film. In addition, when the thus-oriented film is subjected to a heat treatment, temperature of heat is arranged to be a predetermined temperature as to prevent adhesion of the films.
