Title: Automatic carrier and control method for the carrier
Inventor: TAKENAKA SHINICHI
IPC: G05D1/02
Filed: 1991-03-15
Abstract: PURPOSE:To improve efficiency for carriage by detecting whether an object to be an obstacle exists in the advancing direction of the own carrier or not and detecting the moving direction and moving speed of the object to be the obstacle. CONSTITUTION:Based on a detection signal from a sensor directed to the front advancing direction of the own carrier, an obstacle detection processing 8 decides whether the object exists in the front advancing direction or not. When it is decided in this obstacle detection processing 8 that the obstacle exists in the front advancing direction, a speed and distance detection processing 9 measures the speed and the distance from the own carrier and a calculation processing 10 calculates a relative space between the own carrier and the object after the lapse of fixed time. Thus, the change amount of a current relative position is calculated from the respective predictive positions of arrival and the speed of the own carrier is controlled so as to be accelerated in an acceleration processing 12 in the case of enlarging the change amount or to be decelerated in a deceleration processing 13 in the case of reducing it.

Title: Operating procedure for screw compressor
Inventor: SHINODA YUUJIROU
IPC: F04B49/00
Filed: 1980-06-05
Abstract: PURPOSE: To improve power efficiency and reduce drastically power consumption by setting an operation of a pole converter of a motor having a simple and low cost constitution and a position of a slide valve responding to the operation of the converter and by performing volume control.  
     CONSTITUTION: When performing volume control, a compressor is operated by a slide valve 4, if it remains in a voluminous operating region, under the control of a fluid pressure valve of a slide valve drive unit 5 operated by pulses emitted from an indicator provided with a compressor. When the operation comes to a specified operating range of small volume, a pole converter of a motor shifts poles and reduces the number of revolution and sets the slide valve 4 to meet the above performance and controls the volume by the slide valve 4. Application of this simple and low cost construction makes its possible to perform extensive volume control with ease. The volume control then prevents a rapid increase in power as well as worsening of power efficiency.
